I don't want to come off as a linux-elitist but it's simply amazing how much easier my job is on linux. A good example recently was setting up some libraries for a C++ program I was writing to show to my class. Most of them were using Windows and visual studio, took about 15 minutes to download all the headers and libs, and show them how to configure a VS solution to link them. Not too big a deal but on linux, it only took about 30 seconds to pacman and gcc -l the lib. Little things like that keep me interested in linux as a dev tool.undefined plz dont hate linux no comment on mac ive never worked on one windows is kind of ok too tags are useful tags13

I really enjoy my old Kindle Touch rather than reading long pdf's on a tablet or desktop. The Kindle is much easier on my eyes plus some of my pdf's are critical documents needed to recover business processes and systems. During a power outage a tablet might only last a couple of days even with backup power supplies, whereas my Kindle is good for at least 2 weeks of strong use.
Ok, to get a pdf on a Kindle is simple - just email the document to your Kindle email address listed in your Amazon –Settings – Digital Content – Devices - Email. It will be <<something>>@kindle.com.
But there is a major usability problem reading pdf's on a Kindle. The font size is super tiny and you do not have font control as you do with a .MOBI (Kindle) file. You can enlarge the document but the formatting will be off the small Kindle screen. Many people just advise to not read pdf's on a Kindle. devRanters never give up and fortunately there are some really cool solutions to make pdf's verrrrry readable and enjoyable on a Kindle
There are a few cloud pdf- to-.MOBI conversion solutions but I had no intention of using a third party site my security sensitive business content. Also, in my testing of sample pdf's the formatting of the .MOBI file was good but certainly not great.
So here are a couple option I discovered that I find useful:
Solution 1) Very easy. Simply email the pdf file to your Kindle and put 'convert' in the subject line. Amazon will convert the pdf to .MOBI and queue it up to synch the next time you are on wireless. The final e-book .MOBI version of the pdf is readable and has all of the .MOBI options available to you including the ability for you to resize fonts and maintain document flow to properly fit the Kindle screen. Unfortunately, for my requirements it did not measure-up to Solution 2 below which I found much more powerful.
Solution 2) Very Powerful. This solution takes under a minute to convert a pdf to .MOBI and the small effort provides incredible benefits to fine tune the final .MOBI book. You can even brand it with your company information and add custom search tags. In addition, it can be used for many additional input and output files including ePub which is used by many other e-reader devices including The Nook.
The free product I use is Calibre. Lots of options and fine control over documents. I download it from calibre-ebook.com. Nice UI. Very easy to import various types of documents and output to many other types of formats such as .MOBI, ePub, DocX, RTF, Zip and many more. It is a very powerful program. I played with various Calibre options and emailed the formatted .MOBI files to my Kindle. The new files automatically synched to the Kindle when I was wireless in seconds. Calibre did a great job!!
The formatting was 99.5% perfect for the great majority of pdf’s I converted and now happily read on my Kindle. Calibre even has a built-in heuristic option you can try that enables it to figure out how to improve the formatting of the raw pdf. By default it is not enabled. A few of the wider tables in my business continuity plans I have to scroll on the limited Kindle screen but I was able to minimize that by sizing the fonts and controlling the source document parameters.
Now any pdf or other types of documents can be enjoyed on a light, cheap, super power efficient e-reader. Let me know if this info helped you in any way.4 -
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.13 -
You wrote a little simple and clean mvc framework to work faster on some new projects. It can "compile" tags as {% var %} or {% array.key %} in the html code with support of {% for arrayOfHash in hash %} foreach construct and nice features, it can call api's callback in a smart way as ghost methods of a class, he can make routes with the route provider. You tested it and made a little example, after you went in the bathroom you read the index code and you started staring at the beauty and elegance of it. You go to bed happy and sleep. The day after you wake up and realize that it's unuseful because there's a lot of mvc framework that surely are better and ready to use, so you lost useful time. Have you ever feel this way?

As I already said on devrant, I'm a freelance web developer and I also often sell my services for teaching, loving that. Currently I'm teaching PHP with 30 students and it's going very well.
But yesterday, I received an offer for giving another course next month, this time on HTML and CSS, for a company I don't know yet. Almost every line of this email is wrong, outdated by 20 years, or just basically meaningless...
So I thought I could do my best to translate this as close as possible to the original, preserving the wrong formulations too, just for you devranters fellas.
"Hello,
I have an offer for a 2 days course for 5 people (level 1+ and/or 2), on HTML5 and CSS3. Below, the program :
1. XHTML AND CSS2 INTRODUCTION
Advantages and benefits of change
Understanding compatibility for different versions of browsers
HTML, XHTML, CSS edition tools : presentation of the different tools
The CSS language : different types of selectors : class of selector, identifier of selector, contextual selectors, grouped selectors
Blocks of text, boxes of text
The CSS1, CSSP, CSS2 properties
Relative and absolute measures units
2. LAYOUT TECHNIQUES
Full CSS, XHTML websites demo
Positioning with the position property, positioning with the float property
Columns creation
Layout for forms
Layout for data tables
Layout for menus
3. INTRODUCTION TO SVG (SCALABLE VECTOR GRAPHICS)
Role and importance of SVG
Using SVG on client side : basic shapes
SVG structure of document, tags examples
Using CSS styles with SVG
Different integration methods for SVG in a XHTML document
4. OPTIMISATION OF JAVASCRIPT CODE
Introduction to DOM and Javascript
Access to document objects : different access techniques, using this keyword, create elements dynamically
Positioning elements with the help of Javascript : positionning elements relatively to the mouse, move elements
Show/hide elements for creating hierarchical menus
Code optimisation techniques : using objects, objects litterals, loops optimisation
Can you please give me your availability ?"
Seriously...
CSS-fucking-1 ! Is it a course for dinosaurs ?
...And if only my rant was just about the program...
It's totally impossible to cover all these subjects in only 2 days with people of different levels and experience.
The guy exactly said to me : "don't worry about the program, it's an old text but they agreed to it anyway. They just want to learn HTML and CSS, some of them already know it but want to learn more, and the others are total beginers.".
And here is the meaning for the "(level 1+ and/or 2)" part in the email.
So... Surprizingly, I accepted the offer, but asked for at least a 3rd day. I'm waiting for their answer, but I'll do it anyway, adapting the course content to the actual students knowledge. I need the money, after all.
Wish me luck...
It's just sad that these formation companies are selling bullshit to clients that just want to learn something useful. It's too often like that, they sell shitty/useless programs and we have to catch up in real time with students that don't understand why they don't learn what was told to them.3 -
The Zen Of Ripping Off Airtable:
(patterned after The Zen Of Python. For all those shamelessly copying airtables basic functionality)
*Columns can be *reordered* for visual priority and ease of use.
* Rows are purely presentational, and mostly for grouping and formatting.
* Data cells are objects in their own right, so they can control their own rendering, and formatting.
* Columns (as objects) are where linkages and other column specific data are stored.
* Rows (as objects) are where row specific data (full-row formatting) are stored.
* Rows are views or references *into* columns which hold references to the actual data cells
* Tables are meant for managing and structuring *small* amounts of data (less than 10k rows) per table.
* Just as you might do "=A1:A5" to reference a cell range in google or excel, you might do "opt(table1:columnN)" in a column header to create a 'type' for the cells in that column.
* An enumeration is a table with a single column, useful for doing the equivalent of airtables options and tags. You will never be able to decide if it should be stored on a specific column, on a specific table for ease of reuse, or separately where it and its brothers will visually clutter your list of tables. Take a shot if you are here.
* Typing or linking a column should be accomplishable first through a command-driven type language, held in column headers and cells as text.
* Take a shot if you somehow ended up creating any of the following: an FSM, a custom regex parser, a new programming language.
* A good structuring system gives us options or tags (multiple select), selections (single select), and many other datatypes and should be first, programmatically available through a simple command-driven language like how commands are done in datacells in excel or google sheets.
* Columns are a means to organize data cells, and set constraints and formatting on an entire range.
* Row height, can be overridden by the settings of a cell. If a cell overrides the row and column render/graphics settings, then it must be drawn last--drawing over the default grid.
* The header of a column is itself a datacell.
* Columns have no order among themselves. Order is purely presentational, and stored on the table itself.
* The last statement is because this allows us to pluck individual columns out of tables for specialized views.
*Very* fast scrolling on large datasets, with row and cell height variability is complicated. Thinking about it makes me want to drink. You should drink too before you embark on implementing it.
* Wherever possible, don't use a database.
If you're thinking about using a database, see the previous koan.
* If you use a database, expect to pick and choose among column-oriented stores, and json, while factoring for platform support, api support, whether you want your front-end users to be forced to install and setup a full database,
and if not, what file-based .so or .dll database engine is out there that also supports video, audio, images, and custom types.
* For each time you ignore one of these nuggets of wisdom, take a shot, question your sanity, quit halfway, and then write another koan about what you learned.
* If you do not have liquor on hand, for each time you would take a shot, spank yourself on the ass. For those who think this is a reward, for each time you would spank yourself on the ass, instead *don't* spank yourself on the ass.
* Take a sip if you *definitely* wildly misused terms from OOP, MVP, and spreadsheets.5 -
Tech Twitter is a fucking joke, unless you're a somewhat accomplished programmer, wrote something interesting / useful, or at the least have contributed anything meaningful that isn't just a repository with Markdown documents in then I don't want to see your fucking stupid inspirational quotes or words of encouragement with thousands of damn retweets. The circle jerk is frankly just unbearable.
There are plenty of developers that you can learn a lot from and that's great, and I don't want to put new developers down, but you're really not in any position to be giving advice or motivational monologues, you're still new, or worse yet, you've literally just started. Behave yourself.
I'm convinced they're all just LARPers who jerk each other off and shut people down when they have "naughty" opinions. They spend more time writing articles about HTML tags or some aspect of JavaScript you can just get from MDN and get a million fucking applause for it. Maybe you'd be a better programmer if you actually did some programming.
Okay I'm done8 -
I have a platform idea, I need feedback
Problem statement: it’s hard to find researchers of specific area, which discourages students to even start looking for research opportunities. The reason for that is because people often look into their own academic circle, and the resource available is simply not enough.
Solution: by scraping Google scholar, generate detailed tag of sub areas for each professors, make a search system for that which will display the most important works of a researcher and what they are working on recently. If possible, invite the researchers to use the platform to add tags of traits they are looking for in students.
I have quite polarized feedback right now, one is the subarea tagging is really useful and academic circle is a problem, other is this is completely useless.
Please let me know what you think.3 -
(tldr: are foriegn keys good/bad? Can you give a simple example of a situation where foriegn keys were the only and/or best solution?)
i have been recently trying to make some apps and their databases , so i decided to give a deeper look to sql and its queries.
I am a little confused and wanted to know more about foreign keys , joins and this particular db designing technique i use.
Can anyone explain me about them in a simpler way?
Firstly i wanted to show you this not much unheard tecnique of making relations that i find very useful( i guess its called toxi technique) :
In this , we use an extra table for joining 2 tables . For eg, if we have a table of questions and we have a table of tags then we should also have a table of relation called relation which will be mapping the the tags with questions through their primary IDs this way we can search all the questions by using tag name and we can also show multiple tags for a question just like stackoverflow does.
Now am not sure which could be a possibile situation when i need a foriegn key. In this particular example, both questions and tags are joined via what i say as "soft link" and this makes it very scalable and both easy to add both questions and new tags.
From what i learned about foriegn keys, it marks a mandatory one directional relation between 2 tables (or as i say "hard a to b" link)
Firstly i don't understand how i could use foriegn key to map multiple tags with a question. Does that mean it will always going to make a 1to1 relationship between 2 tables( i have yet to understand what 11 1mant or many many relations arr, not sure if my terminology is correct)
Secondly it poses super difficulty and differences in logics for adding either a tag or question, don't you think?
Like one table (say question) is having a foreign key of tags ID then the the questions table is completely independent of tag entries.
Its insertion/updation/deletion/creation of entries doesn't affect the tags table. but for tag table we cannot modify a particular tag or delete a tag without making without causing harm to its associated question entries.
if we have to delete a particular tag then we have to delete all its associated questions with that this means this is rather a bad thing to use for making tables isn't it?
I m just so confused regarding foriegn keys , joins and this toxi approach. Maybe my example of stack overflow tag/questions is wrong wrt to foreign key. But then i would like to know an example where it is useful5
