So a few days ago I felt pretty h*ckin professional.

I'm an intern and my job was to get the last 2003 server off the racks (It's a government job, so it's a wonder we only have one 2003 server left). The problem being that the service running on that server cannot just be placed on a new OS. It's some custom engineering document server that was built in 2003 on a 1995 tech stack and it had been abandoned for so long that it was apparently lost to time with no hope of recovery.

"Please redesign the system. Use a modern tech stack. Have at it, she's your project, do as you wish."

Music to my ears.

First challenge is getting the data off the old server. It's a 1995 .mdb file, so the most recent version of Access that would be able to open it is 2010.

Option two: There's an "export" button that literally just vomits all 16,644 records into a tab-delimited text file. Since this option didn't require scavenging up an old version of Access, I wrote a Python script to just read the export file.

And something like 30% of the records were invalid. Why? Well, one of the fields allowed for newline characters. This was an issue because records were separated by newline. So any record with a field containing newline became invalid.

Although, this did not stop me. Not even close. I figured it out and fixed it in about 10 minutes. All records read into the program without issue.

Next for designing the database. My stack is MySQL and NodeJS, which my supervisors approved of. There was a lot of data that looked like it would fit into an integer, but one or two odd records would have something like "1050b" which mean that just a few items prevented me from having as slick of a database design as I wanted. I designed the tables, about 18 columns per record, mostly varchar(64).

Next challenge was putting the exported data into the database. At first I thought of doing it record by record from my python script. Connect to the MySQL server and just iterate over all the data I had. But what I ended up actually doing was generating a .sql file and running that on the server. This took a few tries thanks to a lot of inconsistencies in the data, but eventually, I got all 16k records in the new database and I had never been so happy.

The next two hours were very productive, designing a front end which was very clean. I had just enough time to design a rough prototype that works totally off ajax requests. I want to keep it that way so that other services can contact this data, as it may be useful to have an engineering data API.

Anyways, that was my win story of the week. I was handed a challenge; an old, decaying server full of important data, and despite the hitches one might expect from archaic data, I was able to rescue every byte. I will probably be presenting my prototype to the higher ups in Engineering sometime this week.

Happy Algo!

Yesterday I managed to optimize a query...
Went from 43 seconds to 0.0702 seconds.

For some reason mysql decided to copy the data of 4 huge tables into a temp table and do its operations there... (the copying to temp tale took 42/43 seconds)

Two composite indexes later and I saved the company hours of time over the course of a few months.

Feels good.

I remember some years ago when a professor asked -
"What is the difference between SQL and MySQL?"

And one of the students answered -
Uh... I don't know... SQL is more like a general SQL and MySQL is a personal SQL...

:|

[Interviewer] : How would you use MySQL?

[Student] : your SQL? Can I get mine so that I can use it?

[Interviewer] * confused what to say *

I worked in the same building as another division in my organization, and they found out I had created a website for my group. They said, “We have this database that was never finished. Do you think you could fix it?”

I asked, “What was it developed in?”
He replied, “Well what do you know?”
I said, “LAMP stack: PHP, MySQL, etc.” [this was over a decade ago]

He excitedly exclaimed, “Yeah, that’s it! It’s that S-Q-L stuff.”

I’m a little nervous at this point but I was younger than 20 with no degree, entirely self-taught from a book, and figured I’d check it out - no actual job offer here yet or anything.

They logged me on to a Windows 2000 Server and I become aware it’s a web application written in VB / ASP.NET 2.0 with a SQL Server backend. But most of the fixes they wanted were aesthetic (spelling errors in aspx pages, etc.) so I proceeded to fix those. They hired me on the spot and asked when I could start. I was a wizard to them and most of what they needed was quite simple (at first). I kept my mouth shut and immediately went to a bookstore after work that day and bought an ASP.NET book.

I worked there several years and ended up rewriting that app in C# and upgrading the server and ASP.NET framework, etc. It stored passwords in plaintext when I started and much more horrific stuff. It was in much better shape when I left.

That job was pivotal in my career and set the stage for me to be where I am today. I got the job because I used the word “SQL” in a sentence.

FML. An overreaching supergenius "architect" and a database team:

A: "We have decided that apps should use mysql. Install a MySQL so we match cloud"
DBA: "we don't have an image or experience with MySQL. We have mssql and Oracle "
A: "ok, use mssql in data center and mysql in production cloud"
DBA: "that's... not going to work well"
A: "just do it!"

...

Me, reading this shit, sends email: "ignoring the fact that we have more than 500 queries in this application which will need to be checked and most likely rewritten, how are we supposed to test the mysql queries without production access?"
A: "just use mssql local and MySQL in cloud"
M: "... Just to make sure I understand, you want us to write queries for mssql, test them locally, and then write separate queries, with a separate SQL connection abstraction that deploys to production? Again, how are we going to test this?"
A: "no, use same queries, should be fine"
M: "they really won't, they're different dialects"
A: "do the needful, make work!"

If karma were a thing, this person would have long since exploded into a cloud of atomized blood.

Lol this guy literally asked me to use My OWN sql

Project manager : I want you to do the job by tomorrow.
Me : I can't, there's some problem with MySQL.
PM : Then use somebody else's SQL, but I want the job done by tomorrow!
Me : *weeps in silence*

..Sure, I..I can try that.

Just looked at the anonymous analytics I collect on the security/privacy blog.

No SQL Injection attacks yet (would be useless anyways as I don't use MySQL/MariaDB for the databasing.

Directory Traversal attacks. Really? 🤣

Nice try, guys.

How to deal with mysql errors :

Option 1 : Write better queries
Option 2 : ALTER TABLE

Select * from World where "someone" like '%you%';

No result!

Damn...

Who can lend me his/her SQL? MySQL is showing an error 😂 😂

Today, for fun, I wrote prime number generation upto 1000 using pure single MySQL query.

No already created tables, no procedures, no variables. Just pure SQL using derived tables.

So does this mean that pure SQL statements do not have the halting problem?

Putting an EXPLAIN over the query I could see how MySQL guessed that the total number of calculations would be 1000*1000 even before executing the query in itself and this is amazing ♥️

I have attached a screenshot of the query and if you are curious, I have also left below the plain text.

PS this was a SQL problem in Hackerrank.

MySQL query:

select group_concat(primeNumber SEPARATOR '&') from
(select numberTable.number as primeNumber from

(select cast((concat(tens, units, hundreds)+1) as UNSIGNED) as number from

(select 0 as units union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) unitsTable,
(select 0 as tens union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) tensTable,
(select 0 as hundreds union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) hundredsTable order by number) numberTable

inner join

(select cast((concat(tens, units, hundreds)+1) as UNSIGNED) as divisor from

(select 0 as units union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) unitsTable,
(select 0 as tens union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) tensTable,
(select 0 as hundreds union select 1 union select 2 union select 3 union select 4 union select 5 union select 6 union select 7 union select 8 union select 9) hundredsTable order by divisor) divisorTable

on (divisorTable.divisor<=numberTable.number and divisorTable.divisor!=1)
where numberTable.number%divisorTable.divisor=0
group by numberTable.number having count(*)<=1 order by numberTable.number) resultTable;

I once had to literally hack a Joomla 1.5.x site for a client, because they did not find the passwords (hosting, cms, ftp, mysql). After 5 minutes and a SQL injection I was in like flynn.
The site was already full of hidden links to viagra sellers and stuff... 😂

So we have this long term contractor that EVERY FUCKING TIME says MySQL meaning SQL Server... Like wtf dude? Shut the fuck up...

This happend to me around 2 weeks ago. For some reason, I decied to post this now.

I won the lottery, yey! I mean, bot really, but I am <19yo student, "less than junior dev" in my office, but sonce I am the only one who is capable of working with hardware, I was working month back as a sysadmin for a few days. Our last sysadmin was really good working but really, really toxic guy, so he got fired on a spot after argument with some manager or whatever, no big deal, we could have another guy hired in a week. But, our backup server literally was on fire, all data probably dead because bad capacitor or whatever. This was our only backup of everything at the time. Everyone in full fucking panic mode, we had literally no other working HW we could use for backup, but then comes me, intern employed on his first dev job for 3 months. That day I bought some HW for my own personal server at home (Intel NUC with some Celeron, 4GB DDR4 RAM and two 240GB SSDs for RAID 1. My manager asked everyone in the office for sollution how to survive next 4 days before new server arrives. People there had no idea what tk do and no knowedgle about HW, I just came from a break and offered my components for a week, since there was noone else who can work with HW, servers and stuff like this, manager offered me $500+HW cost if I, random intern, can make it work. I installed Debian on that little PC, created RAID1 from both SSDs, installed MySQL server and mirrored GIT server from our last standing server (we had two before one of them went lit 🔥), made simple Python script to copy all data on that RAID, with some help of our database guy copied whole DB from production to this little computer and edited some PHP so every SQL request made on our server will run on that NUC too. Everything after ±2 hours worked perfectly. Untill a fucking PSU burned in our server and took RAID controller with him in sillicon heaven next night, so we could not access any data unltill we got a new one. Thanks to every god out there, I was able to create software RAID from survived HDDs on our production server and copy all data from that NUC on the servers software RAID and make it working at 3 AM in the night before an exam 😂. Without this, we would be next ±40 hours without aerver running and we might loose soke of our data and customers. So my little skill with Linux, Python, MySQL and most importantly my NUC hardware I got that day running as a backup server saved maybe whole company 😂.
Btw, guess who is now employee of the year with $2500 bonus? 😀
Sorry for bragging and log post, but I was so lucky an so happy when everything worked out, good luck to all sysadmins out there! 👍

TL:DR: Random intern saved company and made some money 😂

Apparently `= NULL` is not a thing in mysql, instead you have to use `IS NULL`... Took me a while to figure out why the fuck my query wasn't returning any results.

>> this === rant
<< true

At beginning of this year, I only knew HTML, JS, and CSS so I just applied for offers like "Jr Apprentice Dev in Front-End"
In a interview call, the woman told me that they will send me a test asking about my JS and HTML5 knowledge.
When I look in my inbox, the mail subject says "Back-end Test".

Then I call the woman:

Me: "Hello, I have received the test mail, but maybe it's wrong. I applied for a Front-End position and the test is about backend! "

She: "Do you have skills in JS and HTML5?"

Me: "Yes!, and CSS3"

She: "Well, the test is about that. JS, jQuery, and HTML5"

Me: "..."

Me: "Sorry, that languages are Front-End. In the subject say 'Back-End' and Back-End is PHP, SQL, MySQL, Java, .Net... I don't know nothing about that. I only know HTML, JS, CSS."

She: "It's the same"

Me: "I sorry but it's not the same. Fron-End is client-side, what users sees. Animation, colors, FXs, buttons, forms... And Back-End is server-side, what users doesn't see."

She: "Well, JS, HTML, and CSS is backend for us. We call it that way too"

Me: "Sorry but that is wrong. I invite you to read some basic info. Now I am confused"

Of course that I am not confused. That idi0t was wrong.
Perhaps recruiters should take some info about areas where they are recruiting... (:T)

Not a rant about anything in particular. Just a summary of some feelings stored in the hateful part of my heart.

Developing for Android: Add this third-party library to your Gradle build. Use (this) built-in Android class to make the thing work.

What? Those three sentences didn't explain it enough? Well, maybe you aren't cut out for this type of thing.

JavaScript: you know how it is.

SQL: You expect a decent-quality answer from stack overflow but you always get an outdated and hacky response and it's using syntax from Microsoft SQL. You need MySQL.

C#: A surprising number of Microsoft forum results ranking high on Google. You click on one in hopes that it will be of any sort of quality. You quickly close the tab and wonder why you ever even had hope.

Literally any REST API: Is it "query" or "q"? "UserID" or "user_id"? Oh, fuck, where's the docs again?

You thought you escaped JavaScript, but it was a trick!: Some bullshit library you downloaded to make your other library work redefined one of the global variables in the project you inherited. Now you get 347 "<x> is not a function" errors in your console. Good luck, asshole.

FontAwesome/ Material fonts/ Any icon font pack: You search "Close" for a close button icon. No results. You search "Simplified railroad crossing sign without the railroad". You get a close icon.

I think that's all of my pent up rage. Each of them were too small for an individual rant so I had to do this essay.

YAY a JOIN query (MySQL) just ran successfully at the first try for the first time of my life!! I never understood joins but slowly getting there I guess :)

I hate that, not only did this error happen, but they weren’t smart enough to hide the MySQL stack trace

I always cringe when I hear people pronounce MySQL as "MySequal" 😂

MySQL has the absolute worst error messages.

"You have an error in your SQL syntax; check the manual that corresponds blah blah near '(some random code line)'".

How vague can you be? It doesn't help that I always find the error in a completely different place to where the message says it is.

I messed up carelessly in production. Learnt how SQL queries bite you in the ass when it knows you are under pressure.

Was hosting an online quiz kinda thing during my college techfest. Tens of thousands of people participating.

Using MySQL as database and thousands of queries were being executed. Everyone were pretty excited as the event just opened up.

None of the teams could solve one particular level. Turns out the solution was wrong and was asked by the organisers to change the solution for that particular level. Usual stuff, right?

Was too lazy to open up the web UI for the back office and so, straight ahead logged in to the MySQL server and ran the UPDATE query on the table consisting of the solutions.

It had been a couple of hours and the organisers came to me with a weird problem. There were no changes in the scoreboard for the last two hours. Everyone were stuck wherever they were. Weird, right?

I then realized.

Fk.

In that dreaded query, I had only run

UPDATE 'qa' SET answer = 'something'

leaving out the where clause, specifying the question to update, like

WHERE qno=13

As a result, solutions to all the questions were updated to the same answer. After hastily fixing everything back, I had the dreaded conversation.

Org: What was the problem?

Me: It was the cache.

Org: Damn thing. Always messes up.

Me: *sheepishly* yeah

Probably the most embarrassing moment in my life, wrt coding 😑

Screw MySQL/MariaDB. Who the fuck thought not to document that utf8 is only 3 bytes and not unicode capable. You have to use utf8mb4 for it to work. Fuck those idiots that don't want to admit they made a mistake and put this info in a footnote on a pricy documentation piece.

i understand some developers like to write wrapper functions to handle tedious things, I even understand how to write dynamic SQL queries, but for the love of fucking god and sanity, NEVER FUCKING DO THIS!!!!

Yes its PHP, but its not even bad PHP, its a fucking abomination from hell of PHP.

MySQL almost gave me a fright 😂😂😂

Hosting a PHP/MySQL application for a really wealthy NGO that must have paid thousands of dollars for the app, and everything works fine but no sanitised inputs and direct SQL statement execution. Just waiting for little Bobby Tables so I can charge them a fortune for recovery 😊

Oh man where to start:

Not wanting to use LINQ because he did not wanted to "download external dependencies"

Not wanting to use prepared statements on their php sql code, and refusing to use pdo because they will "always use mysql"(moved to postgreSQL shortly after I left)

For some reason including a php file that only had ?>......thats it....only ?>

Use c++ but refused to learn oop and use structs for everything, importing stdio.h and printf everything.....like really?

Maybe just nitpicking, but refusing to use the recyclerview pattern on am android app. The implementation was faster after I made the change.

Importing a library for promises instead of using the ones already in the language(JS)

Changing the style of aaaaall p tags instead of using classes as well as refusing to use divs in place of p tags...well...fuck

Hired a new BI developer. She tested reasonably ok in SQL, and certainly showed good strengths in visualising data, plus had a good attitude in the interview. We hired her. She broke her laptop the first day. We got her another then she complained the camera didn't work but didn't realise the lever in front of the camera was to move the privacy shutter off and on.

Assigned her some work of taking queries that are used in a BI tool that targets the transactional database directly, and re-jigging them for Snowflake which we're using as a data warehouse now, aggregating all our data into one place. Yet, she's struggling to understand why the SQL query she's pasted in doesn't work as-is.

I go over it again; the source schemas and tables are this, but in Snowflake we've named them this. She then bemoans how much work that is to change them all - I say use find and replace. She then struggles with Snowflake syntax errors and asks for a guide on T-SQL to Snowflake. I show her Google and say "this is what I did when I hit these problems - search for 'Snowflake equivalent to T-SQL getdate()' or 'how to get current date in Snowflake' but she still doesn't understand. I ask if she's every had to work between T-SQL and MySQL or MySQL and PostgreSQL or Oracle and so on and she says yes. I say the syntax isn't the same, is it? And she goes oh, now I understand.

She scored reasonably in her SQL test but I'm now concerned there's something fundamental missing in her grasp of SQL. I gave her a detailed demo of the tools, I explained in the interview and on her start about our move to a data warehouse for all our apps, and put her through some training plus gave her time to work through our Confluence pages - not expecting she'll remember everything, but more to ensure she recalls they exist and what the general contents are.

Anyhow, that's my rant.

I had spent the last year working on a online store power by woocommerce with over 100k products from various suppliers. This online store utilized a custom API that would take the various formats that suppliers offer their inventory in and made them consistent. Now everything was going swimmingly initially, but then I began adding more and more products using a plug-in called WP all import. I reached around 100k products and the site would take up to an entire minute to load sometimes timing out. I got desperate so I installed several caching plugins, but to no avail this did not help me. The site was originally only supposed to take three to four months but ended up taking an entire year. Then, just yesterday I found out what went wrong and why this woocommerce website with all of these optimizations was still taking anywhere from 60 to 90 seconds to load, or just timing out entirely. I had initially thought that I needed a beefier server so I moved it to a high CPU digitalocean VM. While this did help a little bit, the site was still very slow and now I had very high CPU usage RAM usage and high disk IO. I was seriously stumped the Apache process was using a high amount of CPU and IO along with MYSQL as well. It wasn't until I started digging deeper into the database that I actually found out what the issue was. As I was loading the site I would run 'show process list' in the SQL terminal, I began to notice a very significant load time for one of the tables, so I went to go and check it out. What I did was I ran a select all query on that particular table just to see how full it was and SQL returned a error saying that I had exceeded the maximum packet size. So I was like okay what the fuck...
So I exited my SQL and re-entered it this time with a higher packet size. I ran a query that would count how many rows were in this particular table and the number came out to being in the millions. I was surprised, and what's worse is that this table belong to a plugin that I had attempted to use early in the development process to cache the site. The plugin was deactivated but apparently it had left PHP files within the wp content directory outside of the actual plugin directory, so it's still executing scripts even though the plugin itself was disabled. Basically every time I would change anything on the site, it would recache the whole thing, and it didn't delete any old records. So 100k+ products caching on saves with no garbage collection... You do the math, it's gonna be a heavy ass database. Not only that but it was serialized data, so when it did pull this metric shit ton of spaghetti from the database, PHP then had to deserialize it. Hence the high ass CPU load. I had caching enabled on the MySQL end of things so that ate the ram. I was really desperate to get this thing running.
Honest to God the main reason why this website took so long was because the load times made it miserable to work on. I just thought that the hardware that I had the site on was inadequate. I had initially started the development on a small Linux VM which apparently wasn't enough, which is why I moved it to digitalocean which also seemed to not be enough, so from there I moved to a dedicated server which still didn't seem to be enough. I was probably a few more 60-second wait times or timeouts from recommending a server cluster to my client who I know would not be willing to purchase it. The client who I promised this site to have completed in 3 months and has waited a year. Seriously, I would tell people the struggles that I would go through with this particular site and they would just tell me to just drop the site; just take the money, just take the loss. I refused to, this was really the only thing that was kicking my ass. I present myself as this high-and-mighty developer like I'm just really good at what I do but then I have this WordPress site that's just beating the shit out of me for a year. It was a very big learning experience and it was also very humbling as well, it made me realize that I really don't know as much as I think I might. It was evidence that there is still so much more to learn out there, I did learn a lot from that experience especially about optimizing websites the different types of methods to do that particular lonely on the server side and I'll be able to utilize this knowledge in the future.
I guess the moral of the story is, never really give up. Ultimately things might get so bad that you're running on hopes and dreams. Those experiences are generally the most humbling. Now I can finally present the site that I am basically a year late on to the client who will be so happy that I did not give up on the project entirely. I'll have experienced this feeling of pure euphoria, and help the small business significantly grow their revenue. Helping others is very fulfilling for me, even at my own expense.

Anyways, gonna stop ranting. Running out of characters. If you're still here... Ty for reading :')

I don't know if I'm being pranked or not, but I work with my boss and he has the strangest way of doing things.
- Only use PHP
- Keep error_reporting off (for development), Site cannot function if they are on.
- 20,000 lines of functions in a single file, 50% of which was unused, mostly repeated code that could have been reduced massively.
- Zero Code Comments
- Inconsistent variable names, function names, file names -- I was literally project searching for months to find things.
- There is nothing close to a normalized SQL Database, column ID names can't even stay consistent.
- Every query is done with a mysqli wrapper to use legacy mysql functions.
- Most used function is to escape stirngs
- Type-hinting is too strict for the code.
- Most files packed with Inline CSS, JavaScript and PHP - we don't want to use an external file otherwise we'd have to open two of them.
- Do not use a package manger composer because he doesn't have it installed.. Though I told him it's easy on any platform and I'll explain it.
- He downloads a few composer packages he likes and drag/drop them into random folder.
- Uses $_GET to set values and pass them around like a message contianer.
- One file is 6000 lines which is a giant if statement with somewhere close to 7 levels deep of recursion.
- Never removes his old code that bloats things.
- Has functions from a decade ago he would like to save to use some day. Just regular, plain old, PHP functions.
- Always wants to build things from scratch, and re-using a lot of his code that is honestly a weird way of doing almost everything.
- Using CodeIntel, Mess Detectors, Error Detectors is not good or useful.
- Would not deploy to production through any tool I setup, though I was told to. Instead he wrote bash scripts that still make me nervous.
- Often tells me to make something modern/great (reinventing a wheel) and then ends up saying, "I think I'd do it this way... Referes to his code 5 years ago".
- Using isset() breaks things.
- Tens of thousands of undefined variables exist because arrays are creates like $this[][][] = 5;
- Understanding the naming of functions required me to write several documents.
- I had to use #region tags to find places in the code quicker since a router was about 2000 lines of if else statements.
- I used Todo Bookmark extensions in VSCode to mark and flag everything that's a bug.
- Gets upset if I add anything to .gitignore; I tried to tell him it ignores files we don't want, he is though it deleted them for a while.
- He would rather explain every line of code in a mammoth project that follows no human known patterns, includes files that overwrite global scope variables and wants has me do the documentation.
- Open to ideas but when I bring them up such as - This is what most standards suggest, here's a literal example of exactly what you want but easier - He will passively decide against it and end up working on tedious things not very necessary for project release dates.
- On another project I try to write code but he wants to go over every single nook and cranny and stay on the phone the entire day as I watch his screen and Im trying to code.

I would like us all to do well but I do not consider him a programmer but a script-whippersnapper. I find myself trying to to debate the most basic of things (you shouldnt 777 every file), and I need all kinds of evidence before he will do something about it. We need "security" and all kinds of buzz words but I'm scared to death of this code. After several months its a nice place to work but I am convinced I'm being pranked or my boss has very little idea what he's doing. I've worked in a lot of disasters but nothing like this.

We are building an API, I could use something open source to help with anything from validations, routing, ACL but he ends up reinventing the wheel. I have never worked so slow, hindered and baffled at how I am supposed to build anything - nothing is stable, tested, and rarely logical. I suggested many things but he would rather have small talk and reason his way into using things he made.

I could fhave this project 50% done i a Node API i two weeks, pretty fast in a PHP or Python one, but we for reasons I have no idea would rather go slow and literally "build a framework". Two knuckleheads are going to build a PHP REST framework and compete with tested, tried and true open source tools by tens of millions?

I just wanted to rant because this drives me crazy. I have so much stress my neck and shoulder seems like a nerve is pinched. I don't understand what any of this means. I've never met someone who was wrong about so many things but believed they were right. I just don't know what to say so often on call I just say, 'uhh..'. It's like nothing anyone or any authority says matters, I don't know why he asks anything he's going to do things one way, a hard way, only that he can decipher. He's an owner, he's not worried about job security.

Twenty five goddamn minutes finding an incorrect quote mark in a bloody massive query of mySQL, I need a beer.

Depends. No one took for the job. VSCode is really good for web and Python. I use Visual Studio for c#, c++ and c. Jetbrains for Java stuff, including Android studio.

When writing SQL I usually use vendor-provided editors like MySQL Workbench. They're the tool made for the job.

Visual Studio Code is my generic editor thanks to it's easy-access terminal. Makes running anything a breeze.

It doesn't feel as snappy as other editors though and installing plugins just for intellisense to work can be annoying, which is why I use other tools for other workflows.

Generally, I avoid things like vim. Sorry, but I have a mouse AND a keyboard. Paid for em both, and I intend to use em. Sometimes I wanna find a setting in a menu and not fuck around with config files after googling what the right setting is called.

I used Sublime for a while, but never really got too into it. It's okay.

Hmm I wonder why

Oh hell yeah. I just spent a good few hours optimizing an ok mySQL query and made it so much better and faster. Inner join ftw!!

I started to hate programming.
I started with a lot of enthusiasm 11 years ago up to become in 2 years a full stack dev, a sysadmin and had also my fair share of technical assistance on every device plus hardware experience mounting hardware like cctvs, routers, extenders, industrial printers and so on. At the time you actually had the tools to solve problems and had to crack your head and pull hairs to solve stuff and people actually was developing solution and frameworks that solved stuff.

Today I can't stand anything.

Every midschooler feels entitled to release a framework that is announed as the next cure for cancer. Web dev once was thin and simplistic, now simplicity is considered a bug and not a feature.
I'm working on an angular project for the nth time and the whole environment is a clusterfuck of problems held togheter with kids glue.
Someone did a tool/framework for everything but most of it is barely well tested or mature.

Just to start this project we had to know, beside html/css/js techs like Angular, Kafka, Kubernetes, Docker, git, Lit, npm/node, mysql/sql server, webpack/grunt and the hell that it brings, C#/Asp.NET/MVC/WebAPI, and so on, the list is long.

DAMN. Making a simple page which shows a tabbed view with some grids requires you to know a whole damn stack of technologies that need to cooperate togheter.
It's 10x more complex and I actually find it much less productive than ever.

But what bugs me most, is that 90% of that stuff is bug ridden, has some niche use case or hidden pitfall and stuff because with this whole crap of "hey we put on github you open a ticket" they just release spaghetti code and wait for people to do the debug for them.

Angular puts out a version every 2 days and create destructive updates.

I am so tired that I spend most of my 8hrs binging youtube vids in despair to procrastinate work.
I liked to do this once....

When you want only 10 rows of query result.
Mysql: Select top 10 * from foo.... 😁
Sql server: select top 10 * from foo.. 😁
PostgreSQL: select * from foo limit 10.. 😁

Oracle: select * from foo FETCH NEXT/FIRST 10 ROWS ONLY. 🌚

Oracle, are you trying to be more expressive/verbose because if that's the case then your understanding of verbosity is fucked up just like your understanding of clean-coding, user experience, open source, productivity...
Etc.

During a design meeting, our boss tells me that Vertx's MySQL drivers don't have prepared statements, and that in the past, he's used a library or his own functions to do all the escaping.

"Are you kidding me? Are you insane?"

I insisted that surely he must be wrong; that no one would release a database library without built in support for query arguments. Escaping things by hand is just asinine and a security risk. You should always use the tools in the database drivers, as new security vulnerabilities in SQL drivers can be found and fixed so long as you keep your dependencies up to date.

He told me escaping wasn't as tricky as I made it out to be, that there were some good libraries for it, and insisted Vertx didn't have any built in support for "prepared statements." He also tried to tell us that prepared statements had performance issues.

He searched specifically for "prepared statements" and I was like, "You know they don't have to be called that. They have different names in different frameworks."

Sure enough, a short search and we discovered a function in the Vertx base database classes to allow SQL queries with parameters.

You want oracle database ? Load OCI.dll
You want microsoft SQl ? Load sqlsrv.dll et dotnet.dll
You want mysql ? Its already install

xD why the project have 3 different database :O with less then 2 table each !!! Ffuuuuukkkkkk

This is a true story. We had this subject, called “Web Design” (really, “design”), where we studied HTML, CSS, JavaScript, PHP and MySQL (confusing, right?). And when we get the PHP (e-)book, it was this old PDF (probably downloaded illegally) teaching the legacy 4.0 version of PHP. Anyway, when we had to develop the final project, the sane professor allowed us to use a newer version of PHP — 5.2, released on 2008. I had to follow the rules, so I developed probably the less secure web application I will ever develop. That means no protection from SQL injection, XSS vulnerable and a bunch of other security holes… And that’s how they liked it developed!

I feel ridiculous. While learning SQL databases I ran a query that was supposed to fill up the database with test data for me to play with. The actual result?

8 GB and 330,000+ rows.

Keep in mind this database is on a remote server, so trying to delete it times out after thirty minutes. I’m submitting a ticket right now.

SELECT REPLACE(@COMPANY, @SQL_DEVTEAM, SQL_DEVTEAM_NEW)

So I'm coming out of one that has a focus on this stack (JS [JQuery after weeks of Vanilla JS drilling in our heads, React], Java, MySQL, Python [Django, Bottle], HTML/CSS, and a few web security concepts (XSS, SQL injections).

The whole course has been 4 months learning, 3 weeks working on a final project. Next week is the presentation, so I think I can safely comment on the course.

We moved fast, but that's to be expected. Lecture in the mornings, exercises in the afternoons, assignments due at the beginning of each week. Constantly working towards it and improving. I have been working pretty hard. We were given some help, but had to get a lot of answers online (based God StackOverflow), but that's part of it.

We touched on some concepts like inheritance in JS, Python and Java, OOP and to be open to concepts we don't know so we should be thirsty for that knowledge.

In my off time, I've begun texting myself Node and really trying to double down on React because it seems useful. I realized I was more drawn to the backend, but I was comfortable in front end as well. (Just don't ask me to design anything, my eye for aesthetics/CSS sorcery is terrible.)

The overall experience has been pretty mixed, but we were mostly unsatisfied. We weren't given then help we were promised. The explanations weren't exactly crystal clear, so we would have to teach ourselves and each other quite a bit. We worked together a lot. Some people really fell behind, some caught up, some flew ahead and thrived. (I'm somewhere between caught up and thrived, I recognize where I stand.)

I'm happy I did a bootcamp, they aren't miracle programs, but they at least kick you into place that you are learning and need to continue to learn. (Just kinda wish I had done a different one.)

Feel free to ask about anything concerning it!

My friend is learning PHP and I told him to install xampp but that fucker went nuts and installed MySQL too which didn't allow the xampp's SQL and ended in conflict.
Oh man that's so funny when non programmers don't do what we say.

I had once an sql error that took me two days to resolve it.
The error message was a syntax error but I was using an ORM to write my queries (doctrine with php) .I didn't have too much to debug as the code was pretty simple and clear so I got to the point that I convinced myself that this a bug and I'm gonna try to mess around it to avoid it.

Second day late night, something popped up in my mind '' hey what about those reserved words? Could it be the reason? '' aaaaand BINGO the key '' option '' is a fucking reserved word for mysql.

Tip : always check that list before writing your data models (specially if you're a noob like me)

Beware: Here lies a cautionary tale about shared hosting, backups, and -goes without saying- WordPress.

1. Got a call from a client saying their site presented an issue with a third-party add-on. The vendor asked us to grant him access to our staging copy.

2. Their staging copy, apparently, never got duplicated correctly because, for security reasons, their in-house dev changed the name of the wp-content folder. That broke their staging algo. So no staging site.

3. In order to recreate the staging site, we had to reset everything back to WP defaults. Including, for some reason, absolute paths inside the database. A huge fucking database. Because WordPress.

4. Made the changes directly in a downloaded sql file. Shared hosting, obviously, had an upload limit smaller to the actual database.

5. Spent half an hour trying to upload table by table to no avail.

6. In-house uploads a new, fixed database with the help of the shared hosting provider.

7. Database has the wrong path. Again.

8. In-house performs massive Find and Replace through phpMyAdmin on the production server.

9. Obviously, MySQL crashes instantly and the site gets blocked for over 3 hours for exceeding shared hosting limits.

10. Hosting provider refuses to accept this was caused by such a stupid act and says site needs to be checked because queries are too slow.

11. We are gouging our eyeballs as we see an in-house vs. hosting fight unfold. So we decide to watch a whole Netflix documentary in between.

12. Finally, the hosting folds and enables access to the site, which is obvi not working because, you know, wrong paths.

13. Documentary finishes. We log in again, click restore from backup. Go to bed. Client phones to bless us. Client’s in-house dev probably looking for a cardboard box to pack his stuff first thing in the morning. \_(ツ)_/¯

I run update without where on mysql console on production database Today.

CLASSIC

Just because I needed to fix database after bug fix on the backend of the application.
I thought I wrote good sql statement after executing it on my local machine and then everything got bad.

Luckily it was only one column with some cached statistics data and I checked that it was not important data before I actually started fixing stuff but still ...
Almost got hard attack afterwards.
Made a script to fix this column and it took me only 15 minutes but still...

Bug was caused in part I got no unit tests and application grow after 3 years of development from simple one for one customer and volumes of documents around 50k to over 40 customers and volumes over 2mil per month, don’t know how many pages each, just in one year after we completed all needed features.

I have daily backups and logs of every api operation but still.
I think this got to far for one backend developer.

I got scared that I will loose money cause I am contractor and the only backend developer working on it.
I am so tired of this right now I think I need a break from work.

Responsibility is killing me so hard right now.
It will take a week to get back to normal.

Today,
I tried setting up XAMPP for running my friends code.. it took 5hrs and faced atleast one issue in every step from installation to running.

First
1) XAMPP Did not download itself, found that internet was down.

2) downloaded finally, installation phase went till 98% fatal error, windows collecting info for diagnosis

5)after 3 tries , suddenly it installed successfully

6)Apache force shut, every time I started it

7)1.5 hours later found VM had occupied the port 80, making it shut.
Changed the port

8)PHPmyadmin was recent ,that SQL 5.1 support was not There.

9)Now after setting up new instance of MySql 5.6 , created conflict.
Project referred one instance and PHPmyadmin referred other

10) Changed port numbers and added service entry in windows to make it work

At last the struggle ended up with happy ending.

My installation story precisely

Iam new to PHP development and XAMPP.

# Retrospective as Backend engineer

Once upon a time, I was rejected by a startup who tries to snag me from another company that I was working with.
They are looking for Senior / Supervisor level backend engineer and my profile looks like a fit for them.
So they contacted me, arranged a technical test, system design test, and interview with their lead backend engineer who also happens to be co-founder of the startup.

## The Interview

As usual, they asked me what are my contribution to previous workplace.
I answered them with achievements that I think are the best for each company that I worked with, and how to technologically achieve them.

One of it includes designing and implementing a `CQRS+ES` system in the backend.
With complete capability of what I `brag` as `Time Machine` through replaying event.

## The Rejection

And of course I was rejected by the startup, maybe specifically by the co-founder. As I asked around on the reason of rejection from an insider.

They insisted I am a guy who overengineer thing that are not needed, by doing `CQRS+ES`, and only suitable for RND, non-production stuffs.

Nobody needs that kind of `Time Machine`.

## Ironically

After switching jobs (to another company), becoming fullstack developer, learning about react and redux.
I can reflect back on this past experience and say this:

The same company that says `CQRS+ES` is an over engineering, also uses `React+Redux`.
Never did they realize the concept behind `React+Redux` is very similar to `CQRS+ES`.

- Separation of concern
- CQRS: `Command` is separated from `Query`
- Redux: Side effect / `Action` in `Thunk` separated from the presentation
- Managing State of Application
- ES: Through sequence of `Event` produced by `Command`
- Redux: Through action data produced / dispatched by `Action`
- Replayability
- ES: Through replaying `Event` into the `Applier`
- Redux: Through replay `Action` which trigger dispatch to `Reducer`

---

The same company that says `CQRS` is an over engineering also uses `ElasticSearch+MySQL`.
Never did they realize they are separating `WRITE` database into `MySQL` as their `Single Source Of Truth`, and `READ` database into `ElasticSearch` is also inline with `CQRS` principle.

## Value as Backend Engineer

It's a sad days as Backend Engineer these days. At least in the country I live in.
Seems like being a backend engineer is often under-appreciated.
Company (or people) seems to think of backend engineer is the guy who ONLY makes `CRUD` API endpoint to database.

- I've heard from Fullstack engineer who comes from React background complains about Backend engineers have it easy by only doing CRUD without having to worry about application.
- The same guy fails when given task in Backend to make a simple round-robin ticketing system.
- I've seen company who only hires Fullstack engineer with strong Frontend experience, fails to have basic understanding of how SQL Transaction and Connection Pool works.
- I've seen company Fullstack engineer relies on ORM to do super complex query instead of writing proper SQL, and prefer to translate SQL into ORM query language.
- I've seen company Fullstack engineer with strong React background brags about Uncle Bob clean code but fail to know on how to do basic dependency injection.
- I've heard company who made webapp criticize my way of handling `session` through http secure cookie. Saying it's a bad practice and better to use local storage. Despite my argument of `secure` in the cookie and ability to control cookie via backend.

Since my first post was a success, here's another shameless hack-- in this case, ripping a "closed" database I don't usually have access to and making a copy in MySQL for productivity purposes. That was at a former job as an IT guy at a hardware store, think Lowes/Rona.

We had an old SCO Unix server hosting Informix SQL (curious, anyone here touched iSQL?), which has terminal only forms for the users to handle data, and has keybindings that are strangely vi based (ESC does commit changes. Mindfsck for the users!). To add new price changes to our products, this results to a lengthy procedure inside a terminal form (with ascii borders!) with a few required fields, which makes this rather long. Sadly, only I and a colleague had access to price changes.

Introducing a manager who asks a price change for a brand- not a single product, but the whole product line of a brand we sell. Oh and, those price changes ends later after the weekend (twice the work, back at regular price!)

The usual process is that they send me a price change request Excel document with all the item codes along with the new prices. However, being non technical, those managers write EVERYTHING at hand, cell by cell (code, product name, cost, new price, etc), sometimes just copy pasted from a terminal window

So when the manager asked me to change all those prices, I thought "That's the last time I manually enter all of this sh!t- and so does he". Since I already have a MySQL copy of the items & actual (live) price tables, I wrote a PHP backend to provide a basic API to be consumed to a now VBA enhanced Excel sheet.

This VBA Excel sheet had additional options like calculating a new price based on user provided choices ("Lower price by x $ or x %, but stay above cost by x $ or x %"), so the user could simply write back to back every item codes and the VBA Excel sheet will fetch & display automatically all relevant infos, and calculate a new price if it's a 20% price cut for example.

So when the managers started using that VBA sheet, I had also hidden a button which simply generate all SQL inserts for the prices written in the form, including a "back to regular price" if the user specified an end date, etc.

No more manual form entry for me, no more keyboard pecking for the managers with new prices calculated for them. It was a win/win :)

It's been a while DevRant!

Straight back into it with a rant that no doubt many of us have experienced.

I've been in my current job for a year and a half & accepted the role on lower pay than I normally would as it's in my home town, and jobs in development are scarce.

My background is in Full Stack Development & have a wealth of AWS experience, secure SaaS stacks etc.

My current role is a PHP Systems Developer, a step down from a senior role I was in, but a much bigger company, closer to home, with seemingly a lot more career progression.

My job role/descriptions states the following as desired:

PHP, T-SQL, MySQL, HTML, CSS, JavaScript, Jquery, XML

I am also well versed in various JS frameworks, PHP Frameworks, JAVA, C# as well as other things such as:

Xamarin, Unity3D, Vue, React, Ionic, S3, Cognito, ECS, EBS, EC2, RDS, DynamoDB etc etc.

A couple of months in, I took on all of the external web sites/apps, which historically sit with our Marketing department.

This was all over the place, and I brought it into some sort of control. The previous marketing developer hadn't left and AWS access key, so our GitLabs instance was buggered... that's one example of many many many that I had to work out and piece together, above and beyond my job role.

Done with a smile.

Did a handover to the new Marketing Dev, who still avoid certain work, meaning it gets put onto me. I have had a many a conversation with my line manager about how this is above and beyond what I was hired for and he agrees.

For the last 9 months, I have been working on a JAVA application with ML on the back end, completely separate from what the colleagues in my team do daily (tickets, reports, BI, MI etc.) and in a multi-threaded languages doing much more complicated work.

This is a prototype, been in development for 2 years before I go my hands on it. I needed to redo the entire UI, as well as add in soo many new features it was untrue (in 2 years there was no proper requirements gathering).

I was tasked initially with optimising the original code which utilised a single model & controller :o then after the first discussion with the product owner, it was clear they wanted a lot more features adding in, and that no requirement gathering had every been done effectively.

Throughout the last 9 month, arbitrary deadlines have been set, and I have pulled out all the stops, often doing work in my own time without compensation to meet deadlines set by our director (who is under the C-Suite, CEO, CTO etc.)

During this time, it became apparent that they want to take this product to market, and make it as a SaaS solution, so, given my experience, I was excited for this, and have developed quite a robust but high level view of the infrastructure we need, the Lambda / serverless functions/services we would want to set up, how we would use an API gateway and Cognito with custom claims etc etc etc.

Tomorrow, I go to London to speak with a major cloud company (one of the big ones) to discuss potential approaches & ways to stream the data we require etc.

I love this type of work, however, it is 100% so far above my current job role, and the current level (junior/mid level PHP dev at best) of pay we are given is no where near suitable for what I am doing, and have been doing for all this time, proven, consistent work.

Every conversation I have had with my line manager he tells me how I'm his best employee and how he doesn't want to lose me, and how I am worth the pay rise, (carrot dangling maybe?).

Generally I do believe him, as I too have lived in the culture of this company and there is ALOT of technical debt. Especially so with our Director who has no technical background at all.

Appraisal/review time comes around, I put in a request for a pay rise, along with market rates, lots of details, rates sources from multiple places.

As well that, I also had a job offer, and I rejected it despite it being on a lot more money for the same role as my job description (I rejected due to certain things that didn't sit well with me during the interview).

I used this in my review, and stated I had already rejected it as this is where I want to be, but wanted to use this offer as part of my research for market rates for the role I am employed to do, not the one I am doing.

My pay rise, which was only a small one really (5k, we bring in millions) to bring me in line with what is more suitable for my skills in the job I was employed to do alone.

This was rejected due to a period of sickness, despite, having made up ALL that time without compensation as mentioned.

I'm now unsure what to do, as this was rejected by my director, after my line manager agreed it, before it got to the COO etc.

Even though he sits behind me, sees all the work I put in, creates the arbitrary deadlines that I do work without compensation for, because I was sick, I'm not allowed a pay rise (doctors notes etc supplied).

What would you do in this situation?

Imagine you tell your manager that MySQL is down and he tell you to get someone's else SQL.

So... I've been messing arround with my first VPS (with little knowledge of Linux).
First installed lxde to learn how to do it, then back to the terminal. then I started with Apache, watching online tuts ...
Then I changed for nginx... Looks way better.
Installed my sql, php and got stuck. Dropped it for a few days.
Today I restarted, deleted Apache, mysql, reinstalled nginx, my php (with lots of problems because of old instalations). Everything is working now except php.
After going round and arround I changed my focus to relax a bit, and remembered I still have Apache on the firewall...
OK Apache and other stuff that I installed.
Delete everything
New rules only for nginx and reset.
Cant ssh to the server... What?
Oh... Forgot to add rules to OpenSSH...
No matter, I can access the terminal directly on the website....
And it loads to ldxe, with no user set...
Fuckkkk.
Oh BTW I'm in a trial free period with no support...

Hello devs, I need help from database devs.

The company where I'm interning is a non IT company, so they planned to migrate to a SQL Database from their older MS Access Database.

Since I'm the only IT intern, I'm up against the major devs and hot shots from where my company outsources IT solutions.
They suggested SQL Express.

I have a meeting tomorrow with them, please help me so that I can get better results for my company.
Basically I have to question them about how their decision works better for our firm and why didn't we go for MySQL Enterprise Edition or anything which is much better and cheaper and such critical questions.
Please help me.

The Database would be used to store information about the products manufactured and their parts' history so that in future if there's a problem with the product, it can be looked up in the database so that there can be further replacement or repair processes.

If you don't know how to do it the proper way, just throw something together. :D
Might not be pretty, but it works... (only took about 3 hours)

One day at the office at whoever built Laravel

Dev: sir, most of devs use php, we can use good old php expressi...
Boss: no, dump all of them, we'll create our own functions that do same job
Dev: ok... So our devs will use mysql, we can use sql quer...
Boss: dump them all too, again, we will make our own functions that dont look anything like that
Dev: we can also use standard...
Boss: NO STANDARDS! Creare every single php method or sql query in another method that does the same job...

I really hate PHP frameworks.

I also often write my own frameworks but propriety. I have two decades experience doing without frameworks, writing frameworks and using frameworks.

Virtually every PHP framework I've ever used has causes more headaches than if I had simply written the code.

Let me give you an example. I want a tinyint in my database.

> Unknown column type "tinyint" requested.

Oh, doctrine doesn't support it and wont fix. Doctrine is a library that takes a perfectly good feature rich powerful enough database system and nerfs it to the capabilities of mysql 1.0.0 for portability and because the devs don't actually have the time to create a full ORM library. Sadly it's also the defacto for certain filthy disgusting frameworks whose name I shan't speak.

So I add my own type class. Annoying but what can you do.

I have to try to use it and to do so I have to register it in two places like this (pseudo)...

Types::add(Tinyint::class);
Doctrine::add(Tinyint::class);

Seems simply enough so I run it and see...

> Type tinyint already exists.

So I assume it's doing some magic loading it based on the directory and commend out the Type::add line to see.

> Type to be overwritten tinyint does not exist.

Are you fucking kidding me?

At this point I figure out it must be running twice. It's booting twice. Do I get a stack trace by default from a CLI command? Of course not because who would ever need that?

I take a quick look at parent::boot(). HttpKernel is the standard for Cli Commands?

I notice it has state, uses a protected booted property but I'm curious why it tries to boot so many times. I assume it's user error.

After some fiddling around I get a stack trace but only one boot. How is it possible?

It's not user error, the program flow of the framework is just sub par and it just calls boot all over the place.

I use the state variable and I have to do it in a weird way...

> $booted = $this->booted;parent::boot();if (!$booted) {doStuffOnceThatDependsOnParentBootage();}

A bit awkward but not life and death. I could probably just return but believe or not the parent is doing some crap if already booted. A common ugly practice but one that works is to usually call doSomething and have something only work around the state.

The thing is, doctrine does use TINYINT for bool and it gets all super confused now running commands like updates. It keeps trying to push changes when nothing changed. I'm building my own schema differential system for another project and it doesn't have these problems out of the box. It's not clever enough to handle ambiguous reverse mappings when single types are defined and it should be possible to match the right one or heck both are fine in this case. I'd expect ambiguity to be a problem with reverse engineer, not compare schema to an exact schema.

This is numpty country. Changing TINYINT UNSIGNED to TINYINT UNSIGNED. IT can't even compare two before and after strings.

There's a few other boots I could use but who cares. The internet seems to want to use that boot function. There's also init stages missing. Believe it or not there's a shutdown and reboot for the kernel. It might not be obvious but the Type::add line wants to go not in the boot method but in the top level scope along with the class definition. The top level scope is run only once.

I think people using OOP frameworks forget that there's a scope outside of the object in PHP. It's not ideal but does the trick given the functionality is confined to static only. The register command appears to have it's own check and noop or simply overwrite if the command is issued twice making things more confusing as it was working with register type before to merely alias a type to an existing type so that it could detect it from SQL when reverse engineering.

I start to wonder if I should just use columnDefinition.

It's this. Constantly on a daily basis using these pretentious stuck up frameworks and libraries.

It's not just the palava which in this case is relatively mild compared to some of the headaches that arise. It's that if you use a framework you expect basic things out of the box like oh I don't know support for the byte/char/tinyint/int8 type and a differential command that's able to compare two strings to see if they're different.

Some people might say you're using it wrong. There is such a thing as a learning curve and this one goes down, learning all the things it can't do. It's cripplesauce.

Sometimes lack of confidence in one area reveals oversight cockyness in stronger areas:

Set up a simple login system from Unity engine to php to mysql db, using android device ID as the login id. Set up database column to accept 32 length varchar for MD5 hashed strings, as I knew the method I was getting the android device ID was automatically being hashed that way and more or less was what I wanted anyway.

Spend 2 days wondering why it would insert the logins with 0 issue, but could never retrieve them. Due to lack of web development and PHP skills, I assumed I was screwing up the handling of mysqli_num_rows() (to check whether I was inserting or selecting in the query) or simply screwing up my SQL queries.

Rewrite the code a few times, even went back to a method I had used in the past.

Today it dawned on me that my testing machines deviceID had been getting trimmed to the 32 character limit. Turns out I didn't account for my workstations device ID to be automatically hashed like the android device id is.

For 2 days I was obtaining and sending a 40 character string to a 32 character limit varchar and blaming my lack of PHP skills........

Back to my niche I go!

Got one right now, no idea if it’s the “most” unrealistic, because I’ve been doing this for a while now.

Until recently, I was rewriting a very old, very brittle legacy codebase - we’re talking garbage code from two generations of complete dumbfucks, and hands down the most awful codebase I’ve ever seen. The code itself is quite difficult to describe without seeing it for yourself, but it was written over a period of about a decade by a certifiably insane person, and then maintained and arguably made much worse by a try-hard moron whose only success was making things exponentially harder for his successor to comprehend and maintain. No documentation whatsoever either. One small example of just how fucking stupid these guys were - every function is wrapped in a try catch with an empty catch, variables are declared and redeclared ten times, but never used. Hard coded credentials, hard coded widths and sizes, weird shit like the entire application 500ing if you move a button to another part of the page, or change its width by a pixel, unsanitized inputs, you name it, if it’s a textbook fuck up, it’s in there, and then some.

Because the code is so damn old as well (MySQL 8.0, C#4, and ASP.NET 3), and utterly eschews the vaguest tenets of structured, organized programming - I decided after a month of a disproportionate effort:success ratio, to just extract the SQL queries, sanitize them, and create a new back end and front end that would jointly get things where they need to be, and most importantly, make the application secure, stable, and maintainable. I’m the only developer, but one of the senior employees wrote most of the SQL queries, so I asked for his help in extracting them, to save time. He basically refused, and then told me to make my peace with God if I missed that deadline. Very helpful.

I was making really good time on it too, nearly complete after 60 days of working on it, along with supporting and maintaining the dumpster fire that is the legacy application. Suddenly my phone rings, and I’m told that management wants me to implement a payment processing feature on the site, and because I’ve been so effective at fixing problems thus far, they want to see it inside of a week. I am surprised, because I’ve been regularly communicating my progress and immediate focus to management, so I explain that I might be able to ship the feature by end of Q1, because rather than shoehorn the processor onto the decrepit piece of shit legacy app, it would be far better to just include it in the replacement. I add that PCI compliance is another matter that we must account for, and so there’s not a great chance of shipping this in a week. They tell me that I have a month to do it…and then the Marketing person asks to see my progress and ends up bitching about everything, despite the front end being a pixel perfect reproduction. Despite my making everything mobile responsive, iframe free, secure and encrypted, fast, and void of unpredictable behaviors. I tell her that this is what I was asked to do, and that there should have been no surprises at all, especially since I’ve been sending out weekly updates via email. I guess it needed more suck? But either way, fuck me and my two months of hard work. I mean really, no ego, I made a true enterprise grade app for them.

Short version, I stopped working on the rebuild, and I’m nearly done writing the payment processor as a microservice that I’ll just embed as an iframe, since the legacy build is full of those anyway, and I’m being asked to make bricks without straw. I’m probably glossing over a lot of finer points here too, just because it’s been such an epic of disappointment. The deadline is coming up, and I’m definitely going to make it, now that I have accordingly reduced the scope of work, but this whole thing has just totally pissed me off, and left a bad taste about the organization.

I am a Technical Lead in the department in my company that writes code for our clients that have money but doesn't have the technical expertise to handle the complexities of our own software.

Part of my tasks involve taking care of a few projects written by employees that have left after using third-party tools rather than using our own software. No one else in this department knows these third-party tools, they only know our own, and my *still limited* web development experience means I get dumped these things in my lap.

And I'm SO pissed at these projects and their authors and the manager that let these ex-employees write these things. There is this one project that was managed by two different "developers" (I don't know they deserve this title) at two different times, and it is so riddled with different technologies it makes me want to throw up almost daily.

Don't believe me? Here is a complete list of the dependencies listed in the package.json of this project: babel-polyfill, body-parser, cookie-parser, debug, edge, edge-sql, excel-to-json, exceljs, express, html-inline, jade, morgan, mssql, mysql, pug, ramda, request, rotating-file-stream, serve-favicon, webpack, xlsx, xml2js

What this doesn't even show, is that one part of this project (literally one page) is made using react, react-dom, react-redux, and jade. The other part (again literally one page) is made using Angular and Pug. In case you missed it while picking up your jaw, there's also mssql, mysql, edge and edge-sql. excel-to-json, exceljs, xlsx.

Oh you want *more* juicy details? This project takes the entire data object used by the front-end, stringifies it into JSON, and shoves it into the database *as a single field*. And instead of doing WHERE clauses in the SQL queries, it grabs the entire table, loops, parses the json, and does a condition on it. If even one of those JSON entries gets corrupted, the entire solution breaks because these "developers" don't know what try/catch is.

The client asked for a very simple change in their app, which was to add a button that queries the back-end for a URL, shows it in a modal dialog, after which a button is clicked to verify the link by doing a second query to the back-end before modifying a couple of fields in the page.

This. Took. Me. Two. Months*. Save me. Please, save me.

*between constant context switches between this and other projects that were continuously failing because of their mistakes.

Working at a local seo sweat-shop as "whatever the lead dev does't feel like doing" guy.

Inherit their linux "server".
- Over 500 security updates
- Everything in /var/www is chmod to 777
- Everything in /var/www is owned by a random user that isn't apache
- Every single database is owned by root sql user
- Password for sudo user and mysql root user same as wifi password given to everyone at company.
- Custom spaghetti code dashboard with over 400 files in one directory, db/ api logins spread throughout these files, passwords in plain text.
- Dashboard doesn't have passwords, just usernames to login
- Dashboard database has all customer information including credit card stored in plain text
- Company wifi is shared by other businesses in the area

I suggest that I should try to fix some of these things.

When it comes to choosing a database,  What is the best for a Java project?

1.SQL - MySQL
2.NoSQL- MongoDB

What’s a really expensive MySQL Query? I need to add it to a CMS application for “research purposes”.

FUCK! I've done this a fucking God fucking damn million fucking God fucking damn times fucking before! FUCK! FUUUUCK! FUUUUUUUUUCK!

The best part is that someone is going be paying me once it works............................... FUUUUU K!

tl:dr
i fucking hate that professor for whom i have to work on laboratory project right now.

reason#1
the project is using a stack full with java. JavaScript. react and some weird facebook api of which i have no clue about. not to mention the server side of this application which uses tomcat (ok its java after all) and sql.

well that wouldn't be not so bad if...

reason#2
we wouldn't have to fucking debug his mistakes he put into the fucking prepared code AND his fucking useless instructions how to set up the project for eclipse the first time. not to mention his fucking requirements which make no sense

oh yeah im a student. i can always go and ask him for help if i need any...

reason#3
i have another 70% mandatory course at the same time and that fucker refuses to upload hos sheets in moodle and answer even one fucking question via mail. not to mention no support if I am there unless i have eclipse setup. even through the projects should be build using gradle...

reason#4
oh. and have i mentioned that this course is only about design patterns? uts not like we could see several of them in a java only application. no we literally have to learn java itself. gradle. nodejs JavaScript Extended for react which i have no clue about at the moment... and yes i especially mentioned gradle and nodejs beccause we have to set shit up and not only use a script.

reason#5
and all that wont even give us a grade. no ita simply a pass or fail part of the module which the course is part of.

have i also mentioned that the whole shit should be done in 20 hours according to the schedule

I've alway pronounced it sequel but everyone I know swears it's SQL, so I say that now to fit in.

I feel like a spy, lying to my closest friends everyday...

Fucking MySQL workbench won't even tell me what's wrong with my PL/SQL script. It has no output whatsoever. I click the run button and its like "y'all say sum?"

Why are all tools for SQL development so shit. All the time.

Okay so this question is directed towards anyone with SQL experience. Is MySQL bad to start and bad for beginners? It seems intimidating if Im being honest. and Im confused on how to set everything up and get started and working with SQL and Databases in general

When you have to stay awake until 4:30am uploading and importing 134 .sql files split up from a larger single exported file because for some stupid reason MySQL can only handle importing the data at this insane level of incremental push.

Does anyone know a good book for learning PHP? I want to know more about back-end development and would like some recommendations. I've been programming mostly in Java before and also have experience with SQL, HTML and CSS.

If anyone could suggest a book or any kind of advice I would really appreciate it. I've found some interesting ones online like "PHP & MySQL Web Development – by Luke Welling & Laura Thompson", but would like to hear out first people who know more about this programming language.

I remember back then when we were building an E-commerce website. To maintain good performance the boss insisted using flat table. This was also applied to other projects like GPS. That was already 2013 when NoSQL databases like MongoDB was around already. His concern is he didn't like to risk on new technologies and it would cost money for training instead of using the existing "MySQL" and Microsoft SQL Server.
Everything I learned from that guy was just poop.

so if i get this correctly :

1. mongodb( community server) is going to create some files in my system which will be called "databases/collections/document bullshit via its own special process called mongod (similar to mysql , but ok)

2. my python flask app is going to connect to it via its official driver pymongo (which could be used directly)
3. mongoengine is a library (more of a wrapper on pymongo) providing "easy ways for connecting mongodb via pymongo" (which again could be used directly)

4. flask-mongoengine is library (more of a wrapper on mongoengine providing "easy ways for connecting mongodb via mongoengine via pymongo" (which again could be used directly)

5. flask-pymongo is some another bullshit library/wrapper that took away 6hours of mine which again is "A FUCKING WRAPPER PROVIDING EASY WAYS FOR CONNECTING TO MONGODB VIA PYMONGO"

seriously, fuck web development. Why can't the original driver (i.e pymongo from mongodb devs) could have simpler wrappers? and why does my fucking tutorial instructor had to use the most fucking rarely used flask-mongoengine (which i accidently read as flask-pymongo and got f**ked) to teach newbies? fucking day wasted trying to understand this crap.

I don't like monnopolies, but its somewhat good that the mobile environment is still in the hands of nononsense players like google and oracle(java) . atleast we don't have people releasing wrapper over wrapper over wrapper and then fighting about which wrapper is better to use.
Like , even when devs started cmplaining that android dbs are too difficult to understand, google themselves created an actively supported wrapper that shutted down the fight over which wrapper to use(sqldelight, realm,sql bright etc)

I use mySQL workbench on a daily basis, but I've been having issues with the dark GTK theme not working well with Linux. Should I do a workaround to get workbench to use a light GTK theme, learn to use SQL from the CLI, or go with a third option?

I was reading a few interesting postgreSQL solutions to constrain polymorphic tables (anti-pattern, I know) when something caught my eye.
Some solutions were looked down upon (or looked favorably upon) based on their portability to other rdbms like MySQL.
Is that really so important? I get it, if somehow you decide to change from one to the other for some god-forsaken reason it will make the switch easier. But really, how often will that happen?
I feel there is a tendency to just avoid using SQL beyond the basics.

The company I work in had to build a software that establishes a connection to a MySQL database running on an external server. It doesn't work for the client company because the firewall is very restrictive and only lets through connections on port 80, so we had to build a fucking http server that forwards SQL queries to the MySQL server and returns the result. This is so horrible!
(Running MySQL on port 80 isn't an option as any other connection type than http is blocked by the firewall)

Do you feel that good too when you find the perfect (any)SQL query?
I feel sooo satisfied!

Without a doubt it has to be the internal company search engine/file finding tool @thewamz and I wrote.

The company has a wide UNC network with files scattered all over the place and they need a way to keep track of where the files get moved to (they can and do get moved). The original tool was written in Java/Tomcat and didn't use any frameworks or utilities beyond custom written ones, no orms, and the SQL was just raw strings. The program didn't take into account that files might be moved or deleted so it never removed anything from the database, it just kept adding files and never removing them.

It however never stores files itself, just links to files elsewhere on the UNC network.

It took six months to get it into what might be a stable beta or release candidate state. The user interface is good, very simple and intuitive, the whole thing was rewritten in python/django, there were issues with utf 8 (and mysql not fully supporting utf 8 in its own utf 8 mode), we added a regex search mode (which was sorely lacking), the search used to take up to fifteen minutes however we sped it up to less than a minute (worst case when a user simply puts "^$" as the regex search). It has a multi threaded design which does some checks to ensure it doesn't spawn too many threads and get stuck in constant Gil switching. Still some bugs to fix, like moving the processing of results returned by the server in a web worker so that the content widget doesn't lock up processing millions of search results and moving the back end to use asynchronous python might gain a performance boost. But on the whole I think the system is ready to replace the older system that all the users are frustrated with and constantly complain about.

However the annoying bit is... How to actually get the new system online, while I am responsible for the development of tools and their maintenance, I am not responsible for their initial deployment and that means I have no idea when (or even if) my new tool will even ever be released :/

Mf php and mf mysql database. Fuck you for being such a cunt.wasted my whole fucking day to configure the shit i didnt even broke. All i wanted from your ass was a storage for users but no you piece of shit. And a fucking special mention for php bcz that shit is a stinky piece of work.

All this aside i need a db which can store some data and is easy to use and not an sql one for my very small cllge project. Anything that i can use from my java app.

This is more of an essay than a rant. TLDR at the end. I simply can't choose from all the shitty lecturers I've had, so I'm going to have to go through them one by one. But of background. I'm currently in 7th year of college, I did a multimedia degree in 2 years, a intro course to Software Dev and I'm currently in my final year of my Software Dev degree. So let's start.

Intro Software Course
- we had a database module, which was thought by, I shit you not, the head of the psychology course in the college, she attempted to teach us Databases using access. And not even using SQL, using access GUI components and it's query builder. Need I say more?

1st year software dev
- We had a networking module, the guy that taught the labs, he literally didn't say more than 12 words the entire 12 week semester, his answer to any question you asked him was a grunt and "research it"

- We had a psychology module, I have no fucking idea why, but instead of learning something useful we were told to read this and get in touch with your feelings...

- database module. Yes we actually did SQL here, 12 weeks of select statements and normal form, talked about by a guy in a monotone voice, who sounded like he was contemplating bringing in an assault riffle some day. Also instead of using MySQL he decided to use Ingres. Why I will never know.

2nd Year Software Dev
- We had a module called Algorithms and Data Structures. The lecturer gave us problems she couldn't solve. Simple problems. She was also crazy. Absolutely nuts.

- Object Orientated Programming. I had this lecturer for 3 semesters up until 3rd year. This guy did COBOLT in college, graduated in the 70s or something and went straight into teaching, he taught us Java for nearly 2 years. He literally copied and pasted texts from PDFs and read through them in class. He told myself and another guy at one stage he really didn't care, and was just counting down the days to his retirement.

- Databases again, different lecturer from 1st year, taught us for 2 semesters (24 weeks) and somehow managed to teach us nothing.

3rd Year Software Dev
- software engineering.. This is where the biggest cunt I've ever met was introduced. He arrives into class 15 minutes late every time without fail, talks shit about stuff that has no relevancy to the topic at all, tries to turn everything into a rugby metaphor and every time you ask a question he somehow dodges it and swiftly changes topic. This cunts past profession? A Project Manager. Fucking typical. This dickhead has also thought me 2 other modules.

4th yr Software Dev
- El cunto mentioned above for 2 more modules. Need I say more.
- real time systems, this module took the piss, the module was written by the lecturer which is what earns his space here. Assignments given to us, which required more time to do than we had in labs so we had to work at home, the problem we that is we were using an obscure RTOS called OS9 which would only work on the college computers. When brought to the lecturers attention he just said "figure it out"

Internet of Things - There was 2 lecturers, each lecturer seemingly working off a different plan, one week you'd have one lecturer, the next would be the other one going on about something completely different and unrelated to anything else we'd done.

Some lecturers didn't even make this list as I couldn't be bothered trying to think back about how shit other ones were. These were the ones that always stood out in my mind.

My main take away point from this is that you go to college for the paper which says you have a degree. Learning things that are going to benefit you in a career is up to yourself.

TLDR; 90% of my college lectures were shit. You need to learn useful stuff yourself.

There have been a few :)

If say it's a videos utter project I initially though was good. Apart from loading a view the controllers didn't do anything - my initial thought was some magic was happening behind the scenes.

However, when I opened up the view things changed.

ALL the business logic happened in the view. Everything. Form processing, consuming an app, file uploads, validation, crud ... You name it, it happened in view. The developer created a raw MySQL connection and build his queries by concatenation g strings, the whole system was wide open to sql injection.

Even more annoying was the "source control" he invented. Every file had several copies. I.e. "User(working).php", "user_v3.php" and even "user(working_no_profile_fields_1.php". It wasn't even like there was any consistency in what file was actually used either. A complete mess. The system had around 69 screens too. No idea how the developer got that gig.

What the fuck is this trend of pricing cloud services by the minute? I mean It's fucking great and all that I buy 2 minutes with a sql db but who the fuck actually does that?

After another night working on a server I (strongly) suggest we move our shit to a cloud service. It's cool providing I promise the costs don't rape us blind folded. Seems easy enough, right? Nope it's not.

6 hours later, halfway to becoming a fucking network engineer and I'm more lost than ever.

Seriously can't the fuck AWS and google cloud show a monthly price - even an estimate for generic shit like $x for the average crappy wp blog!

If anyone has some helpful info / experience on the true cost of hosting generic web apps - the retardedly simple app I'm trying to price is:
1 php web application with 150 domains, 3gb mysql db and 30gb ssd.

I gets has 45000 sessions with 250000 page views.

Your help would be greatly appreciated. Currently I'm leaning towards deploying a clone sending 250 000 random requests and praying my $300 cloud platform credit will cover the bill.

Created a CRM for the business which integrated every database in the network, SQL Server, Postgres, Firebird and MySql types. Evolved to writing a series of procedures which replaced a staff members full job though..

Is MongoDB worth learning? I already use MySQL/SQLite but I was thinking of learning it. How is it any different aside from having no SQL

The project my company agreed to work with 1 year ago is totally shitty.

We basically use Python 2, Tornado, MySQL and driver for it from 2005, custom made "ORM" where you have to write SQL in strings in Python, custom asynchronous service that runs jobs and all such...

The rest of the team writes code really badly and only after a year of fucking with this shit we made them do pull requests.

I became totally neurotic because of the shit I have to go through daily at work. I do not develop myself, no new things I have learned in the past year or so. What do I do, devrant? What is your advice?

how to describe the feeling when you started using sql and you had to get the first element from a table via jdbc...
you, obviously, think "oh, the first index is 0, every languages start at 0, so let's take the content at 0!!!" but the ide returns you "0 < 1"
so you don't understand, you stare the code for 20 mins, you start crying, and then you realize sql starts counting from 1 because it pretends to be cool BUT IT DOESN'T

I hate you, sql.

How do you restore partial data from a mysql backup? Don't worry, nothing is wrong, I'm just thinking about how would I restore something if shit hits the fan.

Our current strategy for database backups is to just run mysqldump during the night, using a cronjob (feel freue to suggest a better way ;))

1) Restoring the full db: just read that sql file into the mysql command.

2) Restoring just one (or some) tables: open the file in an IDE, just select the lines you're after, copy them to a new file, read that one (possible issues: let's say we have a table B to which entries of table A are related and we just want to restore table A. We can't nuke table B too, as also table C is refering to it, so we have to do some orphant removal in B afterwards)

3) Restoring selected entries in specific tables: setup a new db, read the full backup in there, dump these entries to a new file and read that into the real db

How do you so it? Any better aproaches/tools?

Was just fucking around with MyBB in order to figure out how it works on the control panel - whatever, right? Install a crap ton of plugins, and quite a lot of them wouldn't install due to an SQL statement being wrong. I check them, and either:

- the plugin ID is specified (it's auto-increment, it really shouldn't be specified at all)
- the database expected an integer and instead got a word

like for fucks sake, it's either 1 or 0 for being default, yet a lot of developers PUT YES OR NO?? HOW IS THAT EVEN REMOTELY AN INTEGER WHAT THE FUCK

So that was my past hour, running through plugin files, finding SQL statements and altering them. Safe to say that for what I got out of the plugins, it really wasn't worth it.

Need advice. I run all my development on a desktop that I have been happy with for years. Now it keep crashing (probably due to forti client which I need for a contract).

I am frozen in looking for a replacement. Will a laptop give me the freedom I want but not enough power and USB options? Will I be wasting 1000k buying one?

I do all sorts of dev: visual studio, eclipse, PHP, c#, Apache, IIS, SQL server, MySQL.

I pretty much have to be prepared for anything.

But I keep thinking a laptop will give me this mobility that I may never use.

I probably should stick with a desktop.

Ok, this question is related to mysql and php.,
Let me state the current situation
I have a db, say "gd".
That db has several tables all with same columns.(i.e same fields for different manufacturers such as product name, cost , stock etc.)
Now i want to know how many tables have the product 'a' in them and what's the cost of 'a' in each of those table.(tables are generated dynamically so I'll never now how many tables are there, well ofcourse i can refer information schema, but just wanted to highlight this fact). So is there a way to achieve this?.. excluding "dump the whole data and then search it" solution.
Plz help, .. sorry for my bad English, .

MySQL has no outer join. Why isn't this fact all over the internet? Why does EVERY FUCKING TUTORIAL list outer join as if it's just as standard as left join?

Worked the whole day on a pretty complex sql query works perfect. Run it on the production server and the hole thing hangs. It's literally the same version of MySQL en a exact clone of the data but still it managed to hang the hole server.

I am in need of a good web host for my personal website... the one I use now is free and therefore sucks. I can't even get external access to the MySQL database and their SQL client sucks.

I never set foreign keys in development in case I need to wipe or truncate stuff. Fuck you sql

When did we decide managing Users through Cloud REST architecture was more secure than having them in an underlying DB?

Because I can't put my finger on exactly why... but I don't like it and I think it's probably less secure... and just spawned from the need to be able to make user management a subscription based service like fucking everything? When a simple MySQL or postgres and some bcrypt somewhere would be both more secure and infinitely cheaper?

I'm more used to consuming REST API's than writing them. Can any you REST peeps help me understand how a REST API could be made as secure as a SQL DB connection for user management?

What do you think the attack vectors are for a REST API User Management? Like... what's the SQL injection of REST API? Pack some extra JSON somewhere or something?

At least if I can have faith my shit's not gonna get hacked because I have to use a 3rd party REST service for User Management of Users to my own fucking app I can maybe sleep tonight.

I absolutely hate it when people pronounce MySQL as MySequel but I have no problems with people pronouncing SQL server as Sequel Server. It's a weird world.

MySQL or SQL Server?

Another question for Database-Gurus:

Is a MySQL table with 4 columns and about 42000+ rows considered 'big' or should the table be split in smaller pieces?

Fuck encoding and fuck PHP!!!
I'm programming a little vocab trainer to get used to php and MySQL. From an old VB vocab trainer I had ca. 2000 txt-files with words and converted them to sql-queries with a simple python script. When SELECTING words with special characters they become encoded properly. But if I UPDATE words their encoding is just fucked up... The table is utf-8 encoded all the columns are utf-8 encoded. The php mysqli connection is utf-8 encoded. My HTML header is utf-8... WTF?

Need some assistance with Drupal and Dreamfactory.

Dreamfactory is an amazing piece of software that basically turns any database into a REST API. I mean any DB from SQL Server to MySQL and all kinds of others. For a connection to the API it uses JWT (JSON Web Tokens) which expire momentarily.

On Drupal, there's wsdata and rest client modules. Restclient is a module where you configure a connection via OAuth or HybridAuth to a rest server. The problem is that the rest server for dreamfactory uses JWT and i'm not sure how to get Drupal and restclient to connect that way.

What’s the appeal of Microsoft SQL Server 2019 over something free like PostgreSQL or MariaDB?

Question for database gurus:

I need to save the openig hours of my clients in a database. Each day should have different opening hours and also the possibility for 2 breaks during the opening hours. There should also be an option for different local holidays for each client.

How to I acomplish this in a clean/performant/scalable way? Thank you for your answers!

TO BE CONTINUED...

It is sometimes shocking to see 10+ developers working on a fairly big project (online quiz). Missing data binding operations here and there, as a result, bunch of sql injections, which successfully led to the entire db full of questions and answers sitting on my desktop.

Vulnerabilities have been reported, took them 2 weeks to understand what happened and fix them.

Pretty sad :/

! rant, I hope😗

To anybody with MySQL/Mariadb experience, how different are these two as I need to pick one for a database application I'm building.

Also, and God will I sound like an amature for asking, is it best practice to debug and deploy the SQL database on an actual hosted server or to just do it on the client PC? I have both and I want to work with whichever one will give me less of a headache.😣

Any feedback would be helpful! The server is Debian and the client is Arch Linux.

Guys, i really need to Specialise in Software engineering, for now i can complete a desktop app with java language and mysql or sql server , what i need to learn or what should i do in general ??

The guy was trying to upload MySQL into a PaaS SQL for last 1 week.

Me: Its SQL not MySQL

Guy: Yeah its PaaS, it works with both.

What if, the newly added JSON datatype in mysql is a way to provide mysql with no-sql-like capabilities.
I mean, some would prefer no-sql cuz they beleive that the tables schema will evolve a lot.
An extra column in mysql table with json datatype called "custom_fields" would do the trick.
What do u think ?

How exactly can you protect your website from sql injections and ddos? The website used php and a mysql database.

Back in school! Happy to say i'm taking classes i genuinely like, which are useful and challenge my brain.

Classes include (but aren't limited to)
SQL (and MS SQL Server, no MySQL sadly)
HTML/CSS/JS
Java

What's your favorite way to expose a SQL database? Or interface with it?

Using mysql workbench right now and it's a bit much for my users.

Is there any version control system for database..

Ofcourse we can keep sql file for mysql db along with our code. Other than that .....

"I mean i want my db backup,
I do not want to do it myself every time,
It should work like pulling code"

Hey so I'm guessing embedding mysql is probably pretty much just creating a custom install under a subdirectory and starting it with a special config file with a custom port etc.

but is it possible with a single package and command line or is mssql possible to embed as well ?

that last interests me more. I prefer t-sql.

[Prestashop question / rant]

Yes, it's not StackOverflow here, neither is it prestashop support forum - but I trust u people most :)

Proper solution for working with big(?) import of products from XML (2,5MB, ~8600 items) to MySQL(InnoDB) within prestashop backoffice module (OR standalone cronjob)

"solutions" I read about so far:
- Up php's max execution time/max memory limit to infinity and hope it's enough
- Run import as a cronjob
- Use MySQL XML parsing procedure and just supply raw xml file to it
- Convert to CSV and use prestashop import functionality (most unreliable so far)
- Instead of using ObjectModel, assemble raw sql queries for chunks of items
- Buy a pre-made module to just handle import (meh)

Maybe an expert on the topic could recommend something?

My family got our first computer when I was in the 1st grade and I really liked it a lot.

After some years I saw someone code and I was like "What's that?". After they explained me what they were doing I was totally hyped and started searching tutorial videos on how to do simple stuff on VB (this was in my 7th grade, I believe).

By the end of my 8th grade I was introduced to a Computer Engineer that lent me a RoR book and tried to teach me the basics.
(Fun fact: around this time I was doing a Habbo clone server with a friend of mine so that we could play with our friends without all the other people poking around).

In high school I took a Computer Technician course where I learnt stuff like VB, C#, PHP, MySQL, some basic CSS/HTML plus some hardware fundamentals.

After that course I tried to enter college and I failed on my first try, so I took a gap year were I worked as a dev for my family's computer repair shop. It was really a good experience to have time for myself while working on what I loved.

Now I'm on the 2nd year of a Bachelor in Computer Engineering (It's more about software than hardware actually), currently working with Java, C, IA-32 Assembly and PL/SQL. My goal is to get a Masters in Software Engineering after it.

No matter how many times I educate them, my colleagues still end up confused between writing conditions in join statement and in where statement.

They think they're both same :'(

How (generally) do offer different persistence layers for an app?

So, I have used lots of apps (sorry, I'm talking a proper software system such as a Web based service (e.g. The Open Source XMPP server 'Openfire') in which you can choose what persistence back end you want (MySql or inbuilt H2/SQL light for example).

Within your code, how do you go about achieving this? Would you delegate the persistence to a separate class, and within that class figure out what the systems settings are and use the right connection string?

I'm currently using Java, Hibernate and would like to offer back ends of MySql, H2 and Redis, but the question is more conceptual than specific.

Many thanks.

So, I am in the last stages of development of a really big project and I need to figure out a way to package future patches and updates for the client in order for them to manually update the project on prod server.

For reasons I cannot specify here, they will not use any automated process, and we need to provide regular patches and updates for the next year.

So I was thinking of using git archive to package changed files from our repo for every new commit, or series of commits, and just give them that, along with any database schema updates as sql files (again, no automation can be used).

We are talking about a large PHP + MySQL app, and cannot use automated deployment strategies.

I feel there must be a better way to do this, but this is the best I could come up with so far.

What do you people think?

Any ideeas?

Being new to NodeJS, I wanted to use the framework for a small script that involved connecting to a MySQL database and updating 1500+ records.

With NodeJS's preference towards functional programming over sequential, I wanted to do things the NodeJS way with callback functions instead how I'm used to doing it, using loops (and all the MySQL functions were async).

I couldn't update all the rows at once, so I wrote a callback function that calls back itself after the SQL statement is executed. A recursive callback function... am I doing this right?
