Call comes down from the CEO and through his "Yes Man" that some investors are coming by to visit and he want to show off the data center and test servers. There are four full racks of storage servers filled with HDDs and each server has 4 to 16 HDDs a piece.
I got told to "make all of the lights blink", which can be epic seeing it in action but my test cycles rarely aligned that way.
All morning I was striping RAID arrays and building short mixed I/O tests to maximize "LED blinking" for the boss's henchman.
Investors apparently live/die by blinking light progress and it was all on me to get everything working.21 -
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.18 -
--- GitHub 24-hour outage post mortem ---
As many of you will remember; Github fell over earlier this month and cracked its head on the counter top on the way down. For more or less a full 24 hours the repo-wrangling behemoth had inconsistent data being presented to users, slow response times and failing requests during common user actions such as reporting issues and questioning your career choice in code reviews.
It's been revealed in a post-mortem of the incident (link at the end of the article) that DB replication was the root cause of the chaos after a failing 100G network link was being replaced during routine maintenance. I don't pretend to be a rockstar-ninja-wizard DBA but after speaking with colleagues who went a shade whiter when the term "replication" was used - It's hard to predict where a design decision will bite back and leave you untanging the web of lies and misinformation reported by the databases for weeks if not months after everything's gone a tad sideways.
When the link was yanked out of the east coast DC undergoing maintenance - Github's "Orchestrator" software did exactly what it was meant to do; It hit the "ohshi" button and failed over to another DC that wasn't reporting any issues. The hitch in the master plan was that when connectivity came back up at the east coast DC, Orchestrator was unable to (un)fail-over back to the east coast DC due to each cluster containing data the other didn't have.
At this point it's reasonable to assume that pants were turning funny colours - Monitoring systems across the board started squealing, firing off messages to engineers demanding they rouse from the land of nod and snap back to reality, that was a bit more "on-fire" than usual. A quick call to Orchestrator's API returned a result set that only contained database servers from the west coast - none of the east coast servers had responded.
Come 11pm UTC (about 10 minutes after the initial pant re-colouring) engineers realised they were well and truly backed into a corner, the site was flipped into "Yellow" status and internal mechanisms for deployments were locked out. 5 minutes later an Incident Co-ordinator was dragged from their lair by the status change and almost immediately flipped the site into "Red" status, a move i can only hope was accompanied by all the lights going red and klaxons sounding.
Even more engineers were roused from their slumber to help with the recovery effort, By this point hair was turning grey in real time - The fail-over DB cluster had been processing user data for nearly 40 minutes, every second that passed made the inevitable untangling process exponentially more difficult. Not long after this Github made the call to pause webhooks and Github Pages builds in an attempt to prevent further data loss, causing disruption to those of us using Github as a way of kicking off our deployment processes (myself included, I had to SSH in and run a git pull myself like some kind of savage).
Glossing over several more "And then things were still broken" sections of the post mortem; Clever engineers with their heads screwed on the right way successfully executed what i can only imagine was a large, complex and risky plan to untangle the mess and restore functionality. Github was picked up off the kitchen floor and promptly placed in a comfy chair with a sweet tea to recover. The enormous backlog of webhooks and Pages builds was caught up with and everything was more or less back to normal.
It goes to show that even the best laid plan rarely survives first contact with the enemy, In this case a failing 100G network link somewhere inside an east coast data center.

So my friend was in a hurry when she was setting up the passocde for her phone and later she forgot the code.
So she takes it to the service center.
SC guy: Ma'am we have to do bla bla bla. And you will lose your data. It will cost you around $10.
She just came back and later gave me the phone.
*unlocks bootloader *
*flashes a custom recovery*
*delete passcode file*
Phone is now unlocked with all the data intact.
PS: I got a small treat at McDonald's. 😋6 -
So probably about a decade ago at this point I was working for free for a friend's start-up hosting company. He had rented out a high-end server in some data center and sold out virtualized chunks to clients.
This is back when you had only a few options for running virtual servers, but the market was taking off like a bat out of hell. In our case, we used User-Mode Linux (UML).
UML is essentially a kernel hack that lets you run the kernel in user space. That alone helps keep things separate or jailed. I'm pretty sure some of you can shed more light on it, but that's as I understood it at the time and I wasn't too shabby at hacking the kernel when we'd have driver issues.
Anyway, one of the ways my friend would on-board someone was to generate a new disk image file, mount it, and then chroot to that mount path. He'd basically use a stock image to do this and then wipe it out before putting it live.
I'm not sure exactly what he was doing at the time, but I got a panicked message on New Years Day saying that he had deleted everything. By everything, he had done an rm -fr /home as root on what he had thought was the root of a drive image.
It wasn't an image. It was the host server.
In the stoke of a single command, all user data was lost. We were pretty much screwed, but I have a knack for not giving up - so I spent a ton of time investigating linux file recovery.
Fun fact about UML - since the kernel runs in user space as a regular ol' process, anything it opens is attached to that process. I had noticed that while the files were "gone", I could still see disk usage. I ended up finding the images attached to their file pointers associated with each running kernel - and thankfully all customers were running at the time.
The next part was crazy, and I still think is crazy. I don't remember the command, but I had to essentially copy the image from the referenced path into a new image file, then shutdown the kernel and power it back on from the new image. We had configs all set aside, so that was easy. When it finally worked I was floored.
Rinse and repeat, I managed to drag every last missing bit out of /proc - with the only side effect being that all MySQL databases needed to be cleaned up.3 -
"Ad targeters are pulling data from your browser’s password manager"
---
Well, fuck.
"It won't be easy to fix, but it's worth doing"
Just check for visibility or like other password managers handle it iirc: assign a unique identifier based on form content and fill that identifier only.
---
"Nearly every web browser now comes with a password manager tool, a lightweight version of the same service offered by plugins like LastPass and 1Password. But according to new research from Princeton's Center for Information Technology Policy, those same managers are being exploited as a way to track users from site to site.
The researchers examined two different scripts — AdThink and OnAudience — both of are designed to get identifiable information out of browser-based password managers. The scripts work by injecting invisible login forms in the background of the webpage and scooping up whatever the browsers autofill into the available slots. That information can then be used as a persistent ID to track users from page to page, a potentially valuable tool in targeting advertising."

I was part of a on-call rotation. We had ~800 microsites with decent traffic on this one box, because that's a good idea...
One day the box was experiencing kernel panics and causing core dumps. After exhausting every possiblity I decided it was time to restart the box:
sudo shutdown now
Missed the -r and the box was not accessible remotely. Had to wait for someone at the data center to terminal in.
Downtime was ~2 hours.
This was caused by a crontab that automatically ran apt-get update & apt-get upgrade... Also made by me... None of this should have worked or allowed to be done! -
I fucking swear the servers in the data center know when the fuck I'm going on vacation.
YOU CHOOSE TO DIE NOW YOU PIECE OF SHIT!?
It's okay. It is no longer a critical box, but gah dammit.2 -

Should’ve posted this after it happened, but it requires a bit of background anyway.
There’s this guy that oversees our OpenStack environment. My team often make jokes and groan about him in private because he’s so overbearing. A few months back, he had to take us to our data center to show us our new racks, and he kept saying stupid stuff like “you break this and it costs me $30,000” as if he owns everything. He’s just... one of THOSE people. Always speaks in such a condescending way. We make jokes that he is our “best friend”.
Our company is shifting most of our products to the cloud in response to the coronavirus (trying to make it an opportunity for “innovation”). This has involved some structural and responsibility changes in our department, and long story short, I’m now heading the OpenStack environment alongside other projects.
This means going through grueling 1-on-1 meetings with our “best friend”. It’s not too bad, I can be pretty patient with people, so I didn’t mind too much at first. Then a few things happened.
1. He sent a shared folder that he owned containing info related to the environments. Several documents were outdated and incomplete, so I downloaded them, corrected them, and then uploaded the documents to my teams file share, as I was supposed to since we now own the projects.
2. Several files were missing, and when I asked about them, he said “Oh, did you refresh the browser?”. I told him no, that I downloaded them locally and republished them to my teams server, because he was supposed to hand everything off to us at once. He says “Well, silly, how are you going to get updates if you’re looking at them locally?” and kind of chuckles at me like I’m stupid.
3. He insists on training me how to remote into one of the servers to check on cluster space, which in itself is fine. I understand others wanting to make sure things will be done right by the people who come after them. But he tells me to download SuperPutty. I tell him, “oh no, that’s alright. I don’t need putty”. He says “oh cool, what tool do you use for ssh?”. I answer him “Just Git. If I want to I can use a CentOs bash terminal too, because we have WSL installed”. He responds “You can’t ssh through Git”.
I was actually a little shocked. I didn’t know if he was serious or not so I was silent for a few seconds before hesitantly saying “yes you can”. He says “this is news to me” and I so I tell him “every single one of our build jobs fetches code from Git with ssh” and he seemed genuinely shocked and surprised by that.... so then it occurs to me to show him that you can ssh in Powershell and that REALLY blew his mind. He would not shut up about it for several minutes. I was amused until it just got annoying.
Needless to say, my team had been previously teasing me about having to work with him, so they found it hilarious when I told them afterwards.8 -
I have this project I've inherited, yea I seem to do that a lot, but this damn thing, has to run in php5.4, has deprecated functions for php7 everywhere and a lot of them and there's no classes anywhere beyond some libraries.
Everything is procedural with random scripts being injected left right and center.
I kid you not,
$thisThing = true;
If(x==y)
require "path/to/some/script.php";
else
require "path/to/a/slightly/different/script.php";
If($thisThing === false){
// well it was modified in that small block about 10 different times
}
Those injected scripts then accept data from the parent scope so, looking at file X, you need to have open file A,B, E, and M to understand where variables have been initialised and what there current state could potentially be.
Basically this thing was bandaid after bandaid for feature requests with 0 refactoring.
Here I am trying to implement some basic functionality (should only take an hour or so + a bit of manual testing) but no, I'm literally at the point of hitting the delete button on the entire project and starting again.rant why you no work what did i do to deserve this alcohol is your friend commented out blocks everywhere even with git there was no deleted code kill me now where the hell did that thing come from cocaine may help is this v2 file the right one don't do drugs18 -

Imagine yourself being a CTO back then.
Brand new Acura NSX. No MacBooks, ThinkPads are hot. Your company has its own skyscraper. CASE tools are just introduced and they’re hotter than blockchain now. You do software architecture in IBM Rational Rose, typing on your Model M and thinking really hard about Java OOP which is very hot right now.
You have Erlang servers at your own data center. You laugh at people writing in COBOL. You excited about aspect-oriented programming.
What a wonderful time.3 -
tldr; Windows security sucks. You as a org-admin cant do anything about it. Encrypt your device. Disable USB Live boot in the bios and protect it with a STRONG password.
First of i just want to say that i DO NOT want to start the good ol' Linux VS Windows debate. I'm just ranting about Windows Security here...
Second, here's why i did all of this. I did all of this mainly becuase i wanted to install some programs on my laptop but also to prove that you can't lock down a Windows pc. I don't recomend doing this since this is against the contract i signed.
So when i got my Laptop from my school i wanted to install some programs on it, sush as VS Code and Spotify. They were not avalible in the 'Software Center' so i had to find another way. Since this was when we still used Windows 7 it was quite easy to turn sticky keys in to a command prompt. I did it this way (https://github.com/olback/...). I decided to write a tutorial while i was at it becuase i didn't find any online using this exact method. I couldn't boot from a USB cause it's disabled in the bios wich is protected by a password. Okey, Sticky keys are now CMD. So let's spam SHIFT 5 times before i log in? Yeah, thanks for the command promt. Running 'whoami' returned 'NT SYSTEM'. Apparantly NT System has domain administator rights wich allowed me to make me an Administrator on the machine. So i installed Everything i wanted, Everything was fine untill it was time to migrate to a new domain. It failed of course. So i handed my Laptop to the IT retards (No offense to people working in IT and managing orgs) and got it back the day after, With Windows 10. Windows 10 is not really a problem, i don't mind it. The thing is, i can't use any of the usual Sticky keys to CMD methods since they're all fixed in W10. So what did i do? Moved the Laptop disk to my main PC and copied cmd.exe to sethc.exe. And there we go again. CMD running as NT System on Windows 10. Made myself admin again, installed Everything i needed. Then i wanted to change my wallpaper and lockscreen, had to turn to PowerShell for this since ALL settings are managed by my School. After some messing arround everything is as i want it now.
'Oh this isnt a problem bla bla bla'. Yes, this is a problem. If someone gets physical access your PC/Laptop they can gain access to Everything on it. They can change your password on it since the command promt is running as NT SYSTEM. So please, protect your data and other private information you have on your pc. Encypt your machine and disable USB Live boot.
Have a good wekend!

Damn maintenance windows. I mean, I get that the SaaS product my boyfriend works on can't go out in the middle of the day. But he just spent weeks on a business trip, with an absolutely mad sleep schedule because he's redesigning their data center (or something. Don't ask me, it's a hardware problem...) and now he's finally coming home today and I'm super excited but all he's going to want to do this weekend is sleep. Even though I'd love to spend Sunday going to this yearly event, or finally getting another round of DnD in (everyone else in the group is available). But nope. Bloody all-hours work is taking away his (and thus my) weekend too.2

So I just started a part time job in a hospital research center - because the processing is long I got a temporary user name and password (that belong to the main HR secretary) so I can start work straight away (mainly data analytics)

Administrator privileges.
I can access edit create or delete everything in the entire fucking database. On my first God damn day.
In the 2nd largest hospital in the fucking country.
Agh. How do systems survive with so many dumb security breaches?4 -
Got to know about OSMC/Kodi last week. Took out my Raspberry Pi. Setup OSMC over the weekend, did all the cable setup for 4 external hard drives and connected to TV via HDMI. After few configurations, I'm all setup. I'm astonished by all the features it provides. Fetching data from TMDb (I had actually created a javaFX app to do this for my local library just last month), remote control from Android as well Web Browser. Enabled UPnP and now I have my complete media center floating around my house network. It is one of the best open source project I have laid my eyes upon. Wish I could attach more pics.6

Never buy crappy, consumer-grade SSDs for use in production servers/RAIDs. This might sound obvious but at the company I used to work for, through a series of bad decisions by management and cheapness, we ended up with the cheapest consumer SSDs you can imagine powering all of our storage.
This turned into a nightmare spanning years of failed hard drives and a continues cycle of ridiculousness. Drive failed after a few days, gets taken out, sent back to manufacturer and then replaced with another equally crappy drive destined to fail within days/weeks.
Our ops people were going to the data center multiple times per week to replace failed drives. Lesson I learned: cheaping out on system-critical hardware and software can have long standing consequences and in the end usually doesn't end up actually saving money when you account for time employees have to spend dealing with issues that result from it. -
Pull-to-refresh in mobile web browsers is useless and annoying.
In mid-2019, the #disable-pull-to-refresh-effect option was removed from chrome://flags on Chrome for Android (version 76) for no apparent reason. The top answer in the Google product forum was to beg for this option to be reinstated through the browser's feedback form ( http://web.archive.org/web/... ). Needless to say, that has been futile.
Why is that a problem? The pull-to-refresh gesture not only is unnecessary due to the quickly accessible refresh button in the menu right next to the URL bar, but also causes unsolicited refreshes when quickly scrolling to the top of the page. This drains both the battery and the mobile data plan, in addition to adding an annoying delay.
I would like to use my web browser like a web browser, not a social media app. Besides, the Twitter web app has its own pull-to-refresh implementation in the notification feed.
Without pull-to-refresh, the user has the freedom to scroll up quickly without risking inadvertently reloading the page. If media was playing while an unwanted pull-to-refresh occurs, the user needs to seek for the last playing position, which could take upwards of a minute if the last position is unknown.
Imagine a desktop/laptop web browser reloading because you scroll against the top. Imagine you reach the top of the page but you have not stopped turning the scroll wheel yet, and then a white circle with a blue spinning refresh icon appears at the center top of the window and the page, and then you have to wait for the page to finish loading, and you also need to seek the last playing position of a video or audio track. Wouldn't that be ridiculous?
Any web browser vendor that enforces pull-to-refresh on its users basically begs users to seek an alternative.7 -

I think I have multiple but this guy stands out.
He was a fellow student at my software development study. Used primarily FOSS systems/software, not because he cared about ethics as much but because that way he could tinker with the software as much as he wanted.
He was always searching for new things to tweak, write, explore and so on. And he shared as much as he could with fellow students.
A few examples of what he did:
- wanted to change something about how Linux worked at its core (he mainly used debian based systems) so he learned how to write kernel modules and wrote his solution.
- wanted to be able to monitor his gas/power usage so he hacked an arduino thing into the power/gas meter and got it to send updates to a messenger at command.
- setup and automated mini data center because fuck it, fun to do.
His thinking was always very creative and to this day I still appreciate what he taught me on that!4 -

What is it with networking guys refusing to do any kind of fault finding? Pretty much everywhere I've worked they seem to be overpaid address hogs who occasionally want everyone to be proud of them for installing a new switch.
Currently seeing a production issue that's clearly due to spikes in packet loss on a certain part of the network - but oh no, it's always "our tests are fine", "we can establish a route no problem", "this is an application level issue", etc.
No you morons, when a dozen unrelated applications hosted on different cloud services fail because none of them can contact anything in your particular subnet in your data center at the same time, it's a damn networking issue. Sort it out.14 -

Can someone help me understand?
I subscribed to a nifty IT-releated magazine, and on its back, there's an ad for "Dedicated root server hosting", nothing unusual at a first glance, but after I read the issue, I decided to humor them and see what it is that they offered, and... It just... Doesn't make sense to me!
An ad for "Dedicated Root Server" - What is a dedicated root server first of all? Root servers of any infrastructure sound pretty important.
But, the ad also boasts "High speed performance with the new Intel Core i9-9900K octa-core processor", that's the first weird thing.
Why would anyone responsible enough want to put an i9 into a highly-reliable root server, when the thing doesn't even support ECC? Also, come on, octa-core isn't much, I deal with servers that have anywhere between 2 and 24 cores. 8 isn't exactly a win, even if it has a higher per-core clock.
Oh, also, further down the ad has a list of, seeming, advantages/specs of the servers, they proclaim that the CPU "incl. Hyper-Threading-Technology"... Isn't that... Standard when it comes to servers? I have never seen a server without hyperthreading so far at my job.
"64 GBs of DDR4 RAM" - Fair enough, 64 gigs is a good amount, but... Again, its not ECC, something I would never put into a server.
"2 x 8 TB SATA Enterprise Hard Drive 7200 rpm" - Heh, "enterprise hard drive", another cheap marketing word, would impress me more if they mentioned an actual brand/model, but I'll bite, and say that at least the 7200 rpm is better than I expected.
"100 GBs of Backup Space" - That's... Really, really little. I've dealt with clients who's single database backup is larger than that. Especially with 2x8 TB HDD (Even accounting for software raids on top)
This one cracks me up - "Traffic unlimited"
Whaaaat?! You are not gonna give me a limit to the total transferred traffic to the internet for my server in your data center? Oh, how generous of you, only, the other case would make the server just an expensive paperweight! I thought this ad was for semi-professionals at least, so why mention traffic, and not bandwidth, the thing that matters much more when it comes to servers? How big of a bandwidth do I get? Don't tell me you use dialup for your "Dedicated Root Server"s!
"Location Germany or Finland" - Fair enough, geolocation can matter when it comes to latency.
"No minimum contract" - Oooh, how kiiiind of you, again, you are not gonna charge me extra for using the server only as long as I pay? How nice!
"Setup Fee £60" - I guess, fair enough, the server is not gonna set itself up, only...
The whole ad is for "monthly from £55.50", that's quite the large fee for setup.
Oh, and a cherry on top, the tiny print on the bottom mentions: "All prices exclude VAT and are a subject to..." blah blah blah.
Really? I thought that this sort of almost customer deceipt is present only in the common people's sphere!
I must say, there's being unimpressed, and then... There's this. Why, just... Why? Anyone understands this? Because I don't...12 -
A couple of years ago, we decide to migrate our customer's data from one data center to another, this is the story of how it goes well.
The product was a Facebook canvas and mobile game with 200M users, that represent approximately 500Gibi of data to move stored in MySQL and Redis. The source was stored in Dallas, and the target was New York.
Because downtime is responsible for preventing users to spend their money on our "free" game, we decide to avoid it as much as possible.
In our MySQL main table (manually sharded 100 tables) , we had a modification TIMESTAMP column. We decide to use it to check if a user needs to be copied on the new database. The rest of the data consist of a savegame stored as gzipped JSON in a LONGBLOB column.
A program in Go has been developed to continuously track if a user's data needs to be copied again everytime progress has been made on its savegame. The process goes like this: First the JSON was unzipped to detect bot users with no progress that we simply drop, then data was exported in a custom binary file with fast compressed data to reduce the size of the file. Next, the exported file was copied using rsync to the new servers, and a second Go program do the import on the new MySQL instances.
The 1st loop takes 1 week to copy; the 2nd takes 1 day; a couple of hours for the 3rd, and so on. At the end, copying the latest versions of all the savegame takes roughly a couple of minutes.
On the Redis side, some data were cache that we knew can be dropped without impacting the user's experience. Others were big bunch of data and we simply SCAN each Redis instances and produces the same kind of custom binary files. The process was fast enough to launch it once during migration. It takes 15 minutes because we were able to parallelise across the 22 instances.
It takes 6 months of meticulous preparation. The D day, the process goes smoothly, but we shutdowns our service for one long hour because of a typo on a domain name.1 -
This is the third part of my ongoing series "The Ballad of the Six Witchers and the Undocumented Java Tool".
In this part, we have the massive Battle of Sparks and Storms.
The first part is here: https://devrant.com/rants/5009817/...
The second part is here: https://devrant.com/rants/5054467/...
Over the last couple sprints and then some, The Witcher Who Writes and the Butchers of Jarfile had studied the decompiled guts of the Undocumented Java Beast and finally derived (most of) the process by which the data was transformed. They even built a model to replicate the results in small scale.
But when such process was presented to the Priests of Accounting at the Temple of Cash-Flow, chaos ensued.
This cannot be! - cried the priests - You must be wrong!
Wrong, the Witchers were not. In every single test case the Priests of Accounting threw at the Witchers, their model predicted perfectly what would be registered by the Undocumented Java Tool at the very end.
It was not the Witchers. The process was corrupted at its essence.
The Witchers reconvened at their fortress of Sprint. In the dark room of Standup, the leader of their order, wise beyond his years (and there were plenty of those), in a deep and solemn voice, there declared:
"Guys, we must not fuck this up." (actual quote)
For the leader of the witchers had just returned from a war council at the capitol of the province. There, heading a table boarding the Archpriest of Accounting, the Augur of Economics, the Marketing Spymaster and Admiral of the Fleet, was the Ciefoh Seat himself.
They had heard rumors about the Order of the Witchers' battles and operations. They wanted to know more.
It was quiet that night in the flat and cloudy plains of Cluster of Sparks and Storms. The Ciefoh Seat had ordered the thunder to stay silent, so that the forces of whole cluster would be available for the Witchers.
The cluster had solid ground for Hive and Parquet turf, and extended from the Connection River to farther than the horizon.
The Witcher Who Writes, seated high atop his war-elephant, looked at the massive battle formations behind.
The frontline were all war-elephants of Hadoop, their mahouts the Witchers themselves.
For the right flank, the Red Port of Redis had sent their best connectors - currency conversions would happen by the hundreds, instantly and always updated.
The left flank had the first and second army of Coroutine Jugglers, trained by the Witchers. Their swift catapults would be able to move data to and from the JIRA cities. No data point will be left behind.
At the center were thousands of Sparks mounting their RDD warhorses. Organized in formations designed by the Witchers and the Priestesses of Accounting, those armoured and strong units were native to this cloudy landscape. This was their home, and they were ready to defend it.
For the enemy could be seen in the horizon.
There were terabytes of data crossing the Stony Event Bridge. Hundreds of millions of datapoints, eager to flood the memory of every system and devour the processing time of every node on sight.
For the Ciefoh Seat, in his fury about the wrong calculations of the processes of the past, had ruled that the Witchers would not simply reshape the data from now on.
The Witchers were to process the entire historical ledger of transactions. And be done before the end of the month.
The metrics rumbled under the weight of terabytes of data crossing the Event Bridge. With fire in their eyes, the war-elephants in the frontline advanced.
Hundreds of data points would be impaled by their tusks and trampled by their feet, pressed into the parquet and hive grounds. But hundreds more would take their place. There were too many data points for the Hadoop war-elephants alone.
But the dawn will come.
When the night seemed darker, the Witchers heard a thunder, and the skies turned red. The Sparks were on the move.
Riding into the parquet and hive turf, impaling scores of data points with their long SIMD lances and chopping data off with their Scala swords, the Sparks burned through the enemy like fire.
The second line of the sparks would pick data off to be sent by the Coroutine Jugglers to JIRA. That would provoke even more data to cross the Event Bridge, but the third line of Sparks were ready for it - those data would be pierced by the rounds provided by the Red Port of Redis, and sent back to JIRA - for good.
They fought for six days and six nights, taking turns so that the battles would not stop. And then, silence. The day was won, all the data crushed into hive and parquet.
Short-lived was the relief. The Witchers knew that the enemy in combat is but a shadow of the troubles that approach. Politics and greed and grudge are all next in line. Are the Witchers heroes or marauders? The aftermath is to come, and I will keep you posted.4 -

At 5:35 Gilfoyle says: "In order to hold that much data we would have to go RAID 0. [...] If we lose even one platter, we lose Melcher's data. Permanently."
But my question is: Why use RAID at all? Just storing the data without RAID would reduce the complexity, and if one disk fails, only the data on that one disk is lost. Also, I doubt speed is a priority at that point, since the whole thing is running on a home broadband connection, which something like a WD Gold data-center-harddrive (200+ MB/s) can easily max out.
Also, wouldn't it be easier to pay the broadband bill out of their own pocket, instead of moving tons of server equipment to Stanford?4 -
When the client wants to deploy a patch to their app that is hosted on the cloud, but wants to do it onsite.
Oh well, might as well visit the data center of the cloud provider -
You all know that these AI dev tools are reading your code right?
It is sending it back to a data center and doing evaluations on the code. This is like handing your code to an unknown entity with no guarantees for privacy or copyright protection.
This concept bothers me and I would have to consult with my employer to even determine if we wanted to take that risk. I think it is just a matter of time before a bad actor takes advantage of this and rips off a company somewhere.8 -
I swear my co worker said we were meeting at the data center at 10pm all week! I call him and he says 10:30. Wtf?!!! Well guess I got some time to read more rants.2

About slightly more than a year ago I started volunteering at the local general students committee. They desperately searched for someone playing the role of both political head of division as well as the system administrator, for around half a year before I took the job.
When I started the data center was mostly abandoned with most of the computational power and resources just laying around unused. They already ran some kvm-hosts with around 6 virtual machines, including a cloud service, internally used shared storage, a user directory and also 10 workstations and a WiFi-Network. Everything except one virtual machine ran on GNU/Linux-systems and was built on open source technology. The administration was done through shared passwords, bash-scripts and instructions in an extensive MediaWiki instance.
My introduction into this whole eco-system was basically this:
"Ever did something with linux before? Here you have the logins - have fun. Oh, and please don't break stuff. Thank you!"
Since I had only managed a small personal server before and learned stuff about networking, it-sec and administration only from courses in university I quickly shaped a small team eager to build great things which would bring in the knowledge necessary to create something awesome. We had a lot of fun diving into modern technologies, discussing the future of this infrastructure and simply try out and fail hard while implementing those ideas.
Today, a year and a half later, we look at around 40 virtual machines spiced with a lot of magic. We host several internal and external services like cloud, chat, ticket-system, websites, blog, notepad, DNS, DHCP, VPN, firewall, confluence, freifunk (free network mesh), ubuntu mirror etc. Everything is managed through a central puppet-configuration infrastructure. Changes in configuration are deployed in minutes across all servers. We utilize docker for application deployment and gitlab for code management. We provide incremental, distributed backups, a central database and a distributed network across the campus. We created a desktop workstation environment based on Ubuntu Server for deployment on bare-metal machines through the foreman project. Almost everything free and open source.
The whole system now is easily configurable, allows updating, maintenance and deployment of old and new services. We reached our main goal for this year which was the creation of a documented environment which is maintainable by one administrator.
Although we did this in our free-time without any payment it was a great year with a lot of experience which pays off now. -
its day 4 of updating documentation and consolidating data.
The webclient has broken on average 4 times a day.
The database took 20+ seconds on updating a password entry.
I explained to my boss the real cost of interrupting my attention with these pauses. I figure it's caused my productivity to go from record high last week to being literally losing about 4 hours a day lost, plus extra time in having to go back through and verify things worked.
The technicians and developers who are working on fixing the database system are apparently quitting left right and center; their company acquired it awhile back, so they don't actually have native developers on it. Yet they still are pushing out new integration features rather than fixing anything.
Yesterday, one of the other people on the documentation project lost half a days work due to the angular updating the local cache, but it never reaching the backend. He came back from lunch, reopened his browser, and all his work was gone. (at least thats what we think happened). So we are hard resetting the program every 10 minutes or so just to make sure it is updating the backend.
The good news is that when it is done, we theoretically will be able to use this to cut back onboarding time and update times by about half, and it'll mean our new nano-server deployment project should be able to spin out with standards that can be referenced properly by everyone, not just the guy with the powershell script that he tinkered with for a particular project and never told anyone else what he did.
Theoretically. -
New twist on an old favorite.
Background:
- TeamA provides a service internal to the company.
- That service is made accessible to a cloud environment, also has a requirement to be made available to machines on the local network so you can develop against it.
- Company is too cheap/stupid to get a s2s vpn to their cloud provider.
- Company also only hosts production in the cloud, so all other dev is done locally, or on production non-similar infra, local dev is podman.
- They accomplish service connectivity by use of an inordinately complicated edge gateway/router/firewall/message translator/ouija board/julienne fry maker, also controlled by said service team.
Scenario:
Me: "Hey, we're cool with signing requests using an x509 cert. That said, doing so requires different code than connecting to an unsecured endpoint. Please make this service accessible to developer machines and lower environments on the internal network so we can, you know, develop."
TeamA: "The service should be accessible to [cloud ip range]"
Me: "Yes, that's a production range. We need to be able to test the signing code without testing in production"
TeamA: "Can you mock the data?"
Me: "The code we are testing is relating to auth, not business logic"
TeamA: "What are you trying to do?"
Me: "We are trying to test the code that uses the x509 you provide to connect to the service"
TeamA: "Can you deploy to the cloud"
Me: "Again, no, the cloud is only production per policy, all lower environments are in the local data center"
TeamA: "can you try connecting to the gateway?"
Me: "Yes, we have, it's not accessible, it only has public DNS, and only allows [cloud ip range]"
TeamA: "it work when we try it"
Me: "Can you please supply repro steps so we can adjust our process"
TeamA: "Yes, log into the gateway and try issuing the call from there"
Me: (╯°□°)╯︵ ┻━┻
tl;dr: Works on my server -
How are Coding Bootcamps and what are they like?
A little background:
I’ve been going to a University (have a year left for a CS degree) and I am so EXTREMELY frustrated. I thought I would get an education but it’s so underwhelming. 95% of it doesn’t involve programming and the classes that do are so elementary that I know more than the professors. By the end of my web design course we had been taught to center text, insert images, insert links, and how to use tables with a single day on CSS using colors.
The OOP courses are all the same, learn variables, types, conditionals, loops, classes, functions, and so forth. Python, C++, and Java. I taught all this to myself when I was 15, I’m 29 now.
I’ve recently gotten extremely interested into full stack web development. .NET Core, React, Typescript. I’m also working with Electron. I’m basically 100% self taught and spend almost every waking moment trying to learn more and apply it.
There’s only one person at my school who has the same passion as me and he’s the president at the coding club but is going into machine learning and big data (I’m the Secretary) and I just wish I could interact with more people who have the same passion. I would love to be challenged. I feel as if I spend more time trying to learn and diagnose problems then applying my knowledge because web development is so complicated when it comes to connecting everything together and I’m still relatively new to it (started like 4 months ago). I’m an extremely fast learner and extremely dedicated so I’m not worried about that being an issue.
I just really want to be a part of a community where I have people who can answer my questions and I don’t have to spend hours or days on google finding a solution to integrating Webpack or using typescript with react, and more. I want to feel challenged.
Can I get this from a boot camp? I recently listened to a podcast from Syntax and it really excited me but I don’t want to be let down again. Either way I’m finishing my degree to get that bullshit $60000 piece of paper but I wouldn’t mind taking a couple months off for something like this if it’s worth it.
I live in CO so if you have any Bootcamps in CO that you recommend, I’d love to hear it and take a trip to check it out in person.
Thanks a bunch!10 -
On the week I went on holiday there was a fire alarm in our data center and the Halon fire suppression system was deployed.
I always miss the excitement.
Apparently our servers rolled over perfectly and we had less than 5 min downtime though, even with 4 killed drives in our SAN. So that's a win.
Kudos to our system administration team, especially the poor bastard who was sat in the data center with his toddler at fuck-my-life-o'clock in the morning.1 -
I'm so glad that I got a CS degree learning Data Structures, Algorithms, Operating systems, Databases, Linear Algebra, Software Engineering, Networking and many more...
How else would I have been able to center a div with CSS or change the Background color?2 -
Windows 10 Action Center yesterday alerted me to set a PIN for my laptop.
Turned on PC this morning and typed in my regular password then realized it wanted the PIN.
Thinking how this feature came to be....
1. Windows wants you to link your login to your Microsoft/Hotmail Account and it makes it a pain in the ass to set a seperate one (Windows 8)
2. 2018 arrived an logins are a pain, everything is autologin or PIN/code based (aka short 'unsecure' passwords)
3. MS backtracks and realizes email logins are too long so they make a partial fix which basically reverts back to the pre-Win8 days of a seperate system login.. except now its called a new feature!
I realized now under enter a PIN the reason for the checkbox that says: Allow symbols and letters. It's a nice way of saying: please type in your old password again.
**Also rant #2: cuz i dont feel like waiting 1hr**
I felt great yesterday when my boss told me apparantly I have like an Expert designation at the company.
Feel like crap today cuz some user is complaining about some report:
- they asked us to create months ago
- now complaining its all wrong but never gave any formal requirements and actually did sign off on it during testing
- FIXED ASAP
HELLO!!!!!!!!!!! STOP MAKING IT SOUND LIKE IT'S MY FAULT U CAN'T BE BOTHERED TO PROVIDE CLEAR REQUIREMENTS AND THEN TAKING FOREVER TO COME BACK WITH UR PROBLEMS AND NOW NEED IT FIXED ASAP BY USING A NEW DATA SOURCE THAT I HAVE NO IDEA WHAT THE FUCK IS SINCE U USED A RANDOM ABBREVIATION LIKE I CAN MIND READ.
IF I COULD MINDREAD, ID BE WORKING ON A PLAN TO GET UR ASS FIRED.....
Happy friday and long weekend... Got 3 days to relax before i need to deal with this shit again...2 -
Last night was dreadful- at 11 pm Dev on my team makes a change to a form with 2 million plus records without informing me and leaves to go out without confirming the change was successful. I get call from the data center at midnight because the app is down. Didn't get done till midnight and now data center boss is blaming me.5

Can you help me to come up with a company name?
I want to provide dev services (mainly mobile apps) but I also want to have couple projects of my own, so I can't go with a name which indicates only mobile apps. This is the keyword list that I have at the moment:
dev
optimal
baltic
digital
digital
app
cyber
data
vision
systems
projects
solutions
apps
systems
tech
development
software
strategy
byte
builder
services
industries
house
Factory
incubator
media
dev
projects
net
tools
system
center
tech
pro
loft
devs
and these are my current ideas:
appswat.com
appdevhouse.com
balticdevs.com
devbaltic.com
balticincubator.com
appdecision.com
balticstrategy.com
appmobservice.com
appmobservices.com
appmobileservice.com
appbaltic.com
devbaltic.com
mobilebaltic.com
databaltic.com
balticcyber.com
solutionmob.com
mobiledevmedia.com
balticmobilevision.com
balticmobilesoftware.com
mobilemediasystem.com
probaltictech.com
But none of them seem good enough :/
What do you think about appbaltic.com or devbaltic.com ? Does this name makes sense for you native speakers?
Baltic because it will be an eastern european company located next to Baltic sea. We will provide dev services and have couple projects of our own.14 -
First day at my job and once I got home I immediately crashed into my bed and woke up at 3 AM.
For some reason I still feel physically tired. Even though I woke up by myself (no distractions from my environment).
+ I feel like having worked out even though I did not. I can feel the muscles aching everywhere in my body.
Anyway back to how it went...
I got there (company) and met a young people like me who are also working in this company for the first time.
Once I saw them + the chief and the leaders, my anxiety kicked in, but I made sure not to show it.
We took photos and saw the cubes (data center cubes) and it felt like I was in a hacking scene from Mr Robot or Watch Dogs lol. It was so cool.
After that we were assigned to our temporary work places and mine was at a place where you get packages from the delivery trucks, cut them, sort them, put etiquettes on them and register them in the system.
Another boy (let's call him Daniel) and me were assigned to this place. He is going to be a sys admin.
The people at this workplace were very chill, cool and mature.
You can joke with them and they will not get offended (looking at you, Twitter) lol.
Daniel however is the opposite.
He is so god damn extroverted that he literally won't stop talking.
At some point he asked me if I was even listening and I admitted that the unconcious side of the brain of mine built a filter over the years that only let's valuable information flow through. When there is no valuable information, I do not process them in my conciousness.
Poor guy got a bit sad, but me whatever. Not my problem. He gave me an headache by talking nonstop nonsense.
Today, when my shift begins, I will learn to do drive a forklift and I'm excited about this.
I do not even need a license for it which you normally need in other companies :D1 -
The networking group at my day job, hooooooolly crap I have some unprintable words. But keeping it professional:
* Days to turn around simple firewall whitelisting requests
* Expecting other teams to know the network layout despite not sharing that information anywhere and going out of their way to not share it
* Adding bureaucracy in the form of separate Word doc forms despite having a ticketing system - for no justifiable reason
* Breaking production systems multiple times per month
* Calling in with problems that are clearly network related, being told it’s our systems, and then the problems magically go away even though they swear they didn’t touch anything
* Outright verifiable lies or vague non-answers when they’re not talking to someone at the director level or a vendor from an outside company on conference calls
* Worse packet loss and throughput on our LAN than my home ISP
Doing anything with these clowns is my single biggest source of stress right now. I can’t wait until we get a full SDN stack set up and then we won’t have to deal with them for day-to-day needs any longer.
My boss swears it’s better that we’re not managing the network directly, but I’m pretty sure my friend’s dog could be loosed into the data center to chew on fiber, and eventually the pairs would be connected in such a way as to improve performance.1 -
Is it normal that no one from the management has even a minimal idea of what is going on? I mean, 90% of the team is completely incompetent, and 100% of the management as well. They know basically nothing about the system we are trying to keep alive.
I hate the corporate way that the manager is more a politician than a professional...
I hate that I have constantly to teach everyone and there is no one who can show me nothing, btw for the same salary... I don't even like this job. We have no access to half of the system we have to maintain, and 50% of the time I'm standing there with 3 managers around me asking how long will it take, while I have no access. I mean... c'mon.
My only hope is the data center they're building nearby, so maybe I can get a job there, or maybe I have to give a try to some junior web dev or network tech position in Amsterdam.
It's such a nice place to cry out my frustrations...4 -
My key ring :)
An old friend (remember the guy who had a miniature Red hat?), gave me an old RAM from a work machine (he worked in data center team).
We had many spare ones so, I picked one and been using it since then.

I have fucking HATED Windows 10 from day one. Now I'm hearing there are new vacillations of this genius programming train wreck that I think is designed to force monetize Microsoft's business model.
After a short while I managed to get to a point where I can maintain W 7. In fact, I'm using my old computer right now. Because I could not get this rant to load onto Devrant website. If you are reading this we know that it is because 10 sucks consistently.
I save my files onto a backup hard drive so I can find 'paper file' type solution for whatever random crap might block me at the keyboard. In fact, I still use paper and file cabinets so "technology" doesn't bring me to a screeching halt every time something like "no record of that account" or "wrong password".
Why the hell does my PASSWORD work from W7 but not from W10?! And it's getting WORSE by the day! I'm about to take a fucking hammer to my new fucking computer. And to that guy who smarmy says something to the effect of 'don't be such a pussy... just fix it and you will be happy.' Well. Fuck you too!
Now. That being said. Anybody have a suggestion on what to try next? And don't say something like, 'take your computer to Micro Center or Geek Squad'. I've done those guys twice each. And for a small phenomenal fee they have each time made things slightly worse plus lost parts of my saved data each time.
Oh. And "reset to previous" doesn't work either.
Suggestions?
Probably better at this point to attempt to solve my own problems wrong for free at this point. Maybe I'll learn to program in Linux or some such thing.

German public service digitization. Websites celebrating the new "digital functionality" of the federal ID card, but if you need to prolong the actual card, you have to visit a public administration center in person, no way to prove your existing valid ID in a zoom meeting although that's de-facto standard accepted even when opening a bank account, plus they have all of my data so they should know I have a valid ID and they could just send the new one to my postal address.
So I have to appear in person at their offices, so I need an appointment, but in times of covid pandemic, appointments are rare and only offered on a day-to-day basis in my hometown, that's why I have to visit their online appointment web app at 7 a.m. in the morning to grab one of the few appointments when they are released.
Don't tempt me to write a script that squats all the other appointment slots to resell at the highest prices...
Situation reminds of the times when it was even harder to get a vaccination against covid, and the media kept reporting about the minority that refused to get vaxxed, so they didn't have to admit there wasn't enough vaccine anyway.
This rant is not about politics, it's about the failure of bureaucracy, but if it was about politics, I would just quote Rezo that it shows who had governed this state for sixteen years.
When I rant about German internet connectivity, people usually reply that the web is much better in Taipeh, Bangalore or Guadalajara, so I can still have some hope that it's not all of the world that's totally lost.
So give me some hope, folks.6 -
I am really having a hard time keeping an "open" mindset with my team...
So when I email you, the junior at your first job and an almost 6 months work experience, with a set of instructions, I do not want inline comments and feedback to the tune of "Yes, I agree. I think we should go ahead" or debates on why, in your opinion.. xyz, because you tested it yourself..
WHERE THE FUCK DID YOU SETUP AND TEST BILLIONS OF ROWS OF DATA ON YOUR MANY MANY MULTI BOX CLUSTER? You live in a data center? Oh, and say "Serverless" one more fucking time....
And so begins the painful process of performance managing you out the door. (You cant fire anybody in South Africa for being a prick. Or useless.)
I am sure there once was a time where you could beat guys like this to within an inch of his life with his own keyboard. If it wasn't wireless I could have strangled him with the cord. Ah, I miss model M's....9 -

Random opinion question:
I'm working on a thing where the user provides a big CSV and we process it and put it in the database, or update existing records.
This data impacts other things, but the data isn't front and center as a group of n the application for them to notice / see again (well they can query for it).
I'm thinking of taking the CSV and then presenting them with a table showing how we processed that data giving them a chance to review it before they commit it to the database...
I like this idea for two reasons:
1. If something goes sideways there's a chance someone will see it and I'm not sure I can do enough validation on a big ass CSV from god knows where to be sure we're going to process it right... (I'm going to do some validation but just can't cover it all)
2. It takes some of the mystery out of what happened / is happening for the user for.
Anyone try this in the past? Seems reasonable, but lots of things do before they go sideways.7 -
Story of my first successful project
Being part of a great team, I've shared in a lot of successes, one I am particularly proud of is my first attempt to use agile methodologies in a deeply waterfall-managment culture.
Time was June/July-ish and we applied for a national quality award where one key element in the application stated how well we handled customer complaint resolution.
While somewhat true (our customer service is the top-shelf good stuff), we did not have a systematic process in resolving customer complaints. Long story short,
the VP lied on her section of the application. Then came the 'emergency', borderline panic meeting (several VPs, managers, etc) to develop a process to better manage
complaints before the in-house inspection in December.
As most top priority projects go, the dev manager allocated 3 developers, 2 DBAs, and any/all network admins we would need (plus all the bureaucratic management that wanted their thumb in the pie).
Fast forward to August, after many, many planning meetings, lost interest, new shiny bouncing balls, I was the only one left on the project. The VP runs into the dev manager in the hallway and asks "Is my program done yet? If its not ready before December with report-able data, we will not win the award."
The <bleep> hit the fan...dev manager comes by...
Frank: "How the application coming along? Almost done?"
Me:"No, haven't really started coding. You moved Jake and Tom over to James's team, Tina quit, and you've had me sidetracked helping other teams because the DBAs are too busy."
Frank: "So, it's excuses. You really think the national quality award auditors care about your excuses? The specification design document has been done for months. This is unacceptable."
Me: "The VP finished up her section yesterday and according to the process, we can't start coding until the document is signed off."
Frank: "Holy f<bleep>ing sh<bleep>t! No one told you *you* couldn't start. You know how to create tables and write code."
Me: "There is no specification to write to. The design document is all about how they plan on reporting the data, not how call agents will be using the application to serve customers."
Frank: "The f<bleep> it isn't. F<bleep>ing monkeys could code against that specification, I helped write it! NO MORE F<bleep>ING EXCUSES! This is your top priority from now on!"
I was 'cleared' to work directly with the call center manager and the VP to develop a fully integrated customer complaint management system before December (by-passing any of the waterfall processes that would get in the way).
I had heard about this 'agile' stuff, attended a few conference tracks on the subject, read the manifesto, and thought "I could do this.".
Over the next month, I had my own 'sprints' and 'scrums' with the manager (at the time, 'agile' was a dirty word so I had to be careful of my words and what info I shared) and by the 2nd iteration had a working prototype.
Feature here, feature there (documenting the 'whys' and 'whats' along the way), and by October, had a full deployed application.
Not thinking I would get a parade or anything, the dev manager came back from a meeting where the VP was showing off the new app to the other VPs (and how she didn't really 'lie' on the application)
Frank: "Everyone is pleased how well the project turned out, except one thing. Erin said you bothered him too much with too many questions."
Me: "Bothered? Did he really say that?"
Frank: "No, not directly, but he said you would stop by his office every day to show him your progress and if he needed you to change anything. You shouldn't have done that."
Me: "Erin really seemed to like the continuous feedback. What we have now is very different than what we started with."
Frank: "Yes, probably because you kept bothering him and not following the specification document. That is why we spend so much time up front in design is so we don't waste management's time, which is exactly what you did."
Me: "We beat the deadline by two months, so I don't think I wasted anyone's time. In fact, this is kind of a big win for us, right?"
Frank: "Not really. There was breakdown in the process. We need better focus on the process, not in these one-hit-wonders."
End the end, the company won the award (mgmt team got to meet the vice president, yes the #2 guy). I know I played a very small, somewhat insignificant role in that victory, I was extremely proud to be part of the team. -
I really wanna get a keg of rum and start sailing across the globe...
Just to spank some devs / managers arses.
The last years were... very demanding regarding security and upgrades.
It hasn't gotten better.
Microsoft leaked it's security key thx to internal debugging and the tool to secure the debugging process so secure data gets filtered was buggy...
I'd guess I already have carpal tunnel after Redmond.
But the really really sad story is: This has become the gold standard.

It took me a month to self taught web dev with jQuery
- made 3 sites for school projects
Took me more than a month to learn the MEAN stack.
- taught it to students as a TA in software engineering class for 3rd year while I was at 4th year.
Took me 3 months approx to learn RoR and Clojurescript at my current work.
- year later I am one of the main devs, and pushed the company towards big Data while implementing scrum and pushing for devtasks priority.
Learned React but I am still struggling to figure out how to start a new project.
And I am still fighting Eleverytime I need to center in CSS.
Am I a bad dev mommy?5 -
I just installed the interior IM app developed by my company's IT center, the way it uses to sync messages is almost common, downloads data from server and adds those conversation to client's window, and I am sure the guys who wrote this stupid thing invoked a same function like pushing message or something else, 'cause my cellphone vibrated like a Morse code machine w/ tons of Adrenaline injected when I press "Open", for almost fucking 1 minute.

I'm quite confused about job market here in germany. Beside studies I'm working in a data center and have already some practical knowledge about programming stuff and managing applications. Although many companies I apply for say I need more experience. How the hell should I collect it if I don't get the chance to do so. Do you have seen this in other countries as well?5

Today I started my first machine in a data center after configuring it :) It feels awesome to contribute in an awesome place like this! Lots of projects ahead of us during Long Shutdown 2, including OS transitioning, hardware upgrades, updating config managers to newer version and so on! I've learned a lot in a week and my confidence is slowly but steadily building :)

Co-workers conversation about the new Google Pixel... "I won't get it because they steal your soul, same reason why I don't have the iPhone with the finger print.. they want to have all your information... blah blah..."
I laugh, because they device doesn't matter... your info gets stolen in transit... so all your snap chat, IG DMs, and all of communication potentially at risk to be "stolen".
Example, Gov't splicing into underwater fiber optic cables and redirecting traffic to a data center...
Understand the tech.. please.2 -

<long post>
To start of I'm a student in the Netherlands, I have just finished finished a support management study and I'm currently starting with a IT Management study on MBO 4 lvl.
At the moment I'm in conflict scout doing the IT Management study or doing a application development study as I just don't know what to do. I kind of want do development as I do it in my free time and I like it but I also want to do data center engineering as I also like to work with the hardware.
Should I take a month break of my study and try to get in contact with company's to work there to finalize my decision or should I just drop in the towel and do this study without knowing if I'm going to like it in the end.
And if you work at a company in the Netherlands do you think i can do some orientation internship at your company or do you guys know some places to look at.

I knew programming was for me, MUCH later in life.
I loved playing with computers growing up but it wasn't until college that I tried programming ... and failed...
At the college I was at the first class you took was a class about C. It was taught by someone who 'just gets it', read from a old dusty book about C, that assumes you already know C... programming concepts and a ton more. It was horrible. He read from the book, then gave you your assignment and off you went.
This was before the age when the internet had a lot of good data available on programming. And it didn't help that I was a terrible student. I wasn't mature enough, I had no attention span.
So I decide programming is not for me and i drop out of school and through some lucky events I went on to make a good career in the tech world in networking. Good income and working with good people and all that.
Then after age 40... I'm at a company who is acquired (approved by the Trump administration ... who said there would be lots of great jobs) and they laid most people off.
I wasn't too sad about the layoffs that we knew were comming, it was a good career but I was tiring on the network / tech support world. If you think tech debt is bad, try working in networking land where every protocols shortcomings are 40+ years in the making and they can't be fixed ... without another layer of 20 year old bad ideas... and there's just no way out.
It was also an area where at most companies even where those staff are valued, eventually they decide you're just 'maintenance'.
I had worked really closely with the developers at this company, and I found they got along with me, and I got along with them to the point that they asked some issues be assigned to me. I could spot patterns in bugs and provide engineering data they wanted (accurate / logical troubleshooting, clear documentation, no guessing, tell them "i don't know" when I really don't ... surprising how few people do that).
We had such a good relationship that the directors in my department couldn't get a hold of engineering resources when they wanted ... but engineering would always answer my "Bro, you're going to want to be ready for this one, here's the details..." calls.
I hadn't seen their code ever (it was closely guarded) ... but I felt like I 'knew' it.
But no matter how valuable I was to the engineering teams I was in support... not engineering and thus I was expendable / our department was seen / treated as a cost center.
So as layoff time drew near I knew I liked working with the engineering team and I wondered what to do and I thought maybe I'd take a shot at programming while I had time at work. I read a bunch on the internet and played with some JavaScript as it was super accessible and ... found a whole community that was a hell of a lot more helpful than in my college years and all sorts of info on the internet.
So I do a bunch of stuff online and I'm enjoying it, but I also want a classroom experience to get questions answered and etc.
Unfortunately, as far as in person options are it felt like me it was:
- Go back to college for years ---- un no I've got fam and kids.
- Bootcamps, who have pretty mixed (i'm being nice) reputations.
So layoff time comes, I was really fortunate to get a good severance so I've got time ... but not go back to college time.
So I sign up for the canned bootcamp at my local university.
I could go on for ages about how everyone who hates boot camps is wrong ... and right about them. But I'll skip that for now and say that ... I actually had a great time.
I (and the handful of capable folks in the class) found that while we weren't great students in the past ... we were suddenly super excited about going to class every day and having someone drop knowledge on us each day was ultra motivating.
After that I picked up my first job and it has been fun since then. I like fixing stuff, I like making it 'better' and easier to use (for me, coworkers, and the customer) and it's fun learning / trying new things all the time. -
I am having an introspective moment as a junior dev.
I am working in my 3rd company now and have spent the avg amount of time i would spent in a company ( 1- 1.5 years)
I find myself in similar problems and trajectories:
1. The companies i worked for were startups of various scales : an edtech platform, an insurance company (branch of an mnc) and a b2b analytics company
2. These people hire developers based on domain knowledge and not innovative thinking , and expect them to build anything that the PMs deem as growth/engagement worthy ( For eg, i am bad at those memory time optimising programming/ ds/algo, but i can make any kind of android screen/component, so me and people like me get hired here)
3. These people hire new PMs based on expertise in revenue generation and again , not on the basis of innovative thinking, coz most of the time these folks make tickets to experiment with buttons and text colors to increase engagement/growth
4. The system goes into chaos mode soon since their are so many cross operating teams and the PMs running around trying to boss every dev , qa and designer to add their changes in the app.
5. meanwhile due to multiple different teams working on different aspects, their is no common data center with up to date info of all flows, products and features. the product soon becomes a Frankenstein monster.
6. Thus these companies require more and more devs and QAs which are cogs in the system then innovative thinkers . the cogs in the system will simply come, dimwittingly add whatever feature is needed and goto home.
7. the cogs in system which also start taking the pain of tracking the changes and learning about the product itself becomes "load bearing cogs" : i.e the devs with so much knowledge of the product that they can be helpful in every aspect of feature lifecycle .
8. such devs find themselves in no need for proving themselves , in no need for doing innovative work and are simply promoted based on their domain knowledge and impact.
My question is simply this : are we as a dev just destined to be load bearing cogs?
we are doing the work which ideally a manager should be doing, ie maintaining confluence docs with end to end technical as well as business logic info of every feature/flow.
So is that the only definition of a Software Engineer in a technical product?
then how come innovations happen in companies like meta Microsoft google open ai etc?
if i have to guess as a far observer, i would say their diversity in different fields helps them mix and match stuff and lead to innovative stuff.
For eg, the android os team in google has helped add many innovative things in google cloud product and vice versa.
same is with azure and windows . windows is now optomissed to run in cloud machines when at one point it was just a horrible memory hogging and slow pc OS
for small companies, 1 ideology/product/domain is their hero ideology/product/domain .
an insurance company tries to experiment with stuff related to insurances,health,vehicles,and the best innovations they come up with is "lets give user a discount in premium if they do 5000 steps a day for an year".
edtech would say "lets do live streaming for children apart from static videos"
but Android team at google said , "since ai team is doing so well, lets include ai in various system apps and support device level models" ~ a much larger innovation as 2 domains combined to make a product
The small companies are not aiming to be an innovative product, they are just aiming to be a monopoly product. and this is kinda sad2 -
The NPC has stated that the personal data of atleast 2000 people was leaked after the attacks on the websites of the philippinian goverment on april 1, the data contains; names,adresses,passwords and school data.
Over 7 administrators of schools, universities and other goverment structures have been called out for not reporting on the leakage of personal info on public facebook groups and violaton of the NPC in under 72 hours.
The representatives of the next structures stood before the comission on the 23 and 24 of april
- Taguig City University
- Department of Education offices in Bacoor City and Calamba City
- the Province of Bulacan
- Philippine Carabao Center
- Republic Central Colleges in Angeles City
- Laguna State Polytechnic University
The agency has reported that none of the organisations had notified about the personal info leakage yet.
This is a good reminder that you should inform about security/personal info breaches everyone that might be related to it as soon as possible, even if it seems unecessary. -
Having to debug a program on a batch of 5000 punched cards and needing days to get them to the data center per mail.
Then you wait days to get the result just to see that it threw an error so you begin to debug what basically means that you change something in your 5000 cards, send them back, wait days, get an error again, make a change... send them back and so on...2 -
My most cutting edge story would be working on Huawei fusionsphere cloud for some big firm.
They needed some scripts to setup servers for their newly built data center which will handle the live feed from traffic cameras from all over the country.
It was during college but I think it still holds the top place except for the new one that I'm working on right now. -
Ok just wanna share things that got me stuck for hours on my recent project and their solution. I hope it’s gonna help someone.
To start with, when I was implementing svg to png, i set an image object’s source with a data url. Normally this is going to trigger the onload hook. However for some fucked up reason it never triggered. The solution is to use setAttribute function and then the hook will be triggered.
Second, you can get rounded triangle by setting stroke width and set stroke linejoin and line cap as round. But remember, if stroke width is 6, then it’s 3 inside and 3 outside.
Third, if you have a rotation of svg element, and later on you want to manually compute the rotated point’s position, it’s most likely some vanilla code is not going to work. You see, when you rotate for x degree, it is actually rotating -x degree. I’m not sure if it’s a bug of my code, but it’s there.
And now the worst thing: if you look up how transform on svg is performed, stackoverflow is going to tell you it’s by order. But that’s somehow not true for my project. If I do set transform to do translation then rotation, the order it was applied is actually reversed. It’s rotation first then translation, like ffs why? Who the fuck said it was in order? It’s clearly in reverse fucking order.
Ok last thing, you can scale svg around it’s center, but absolutely don’t do that because it’s gonna fuck up tanslation and rotation applied to this svg. If you need to scale, translate it first then scale it will be better.
Anyway just some things i encountered. I’m gonna stay away from svg for at least two months now1 -
What the hell am I!? I wonder if you guys can help me...
I've been programming most of my life but I've never actually been a developer by title or job role. I thought maybe if I list what I do and have done someone here could help? I'm sure there are more of you in a similar boat.
- C# and VB dev for some quick DBMS projects to help me understand and mine databases and create a nice simple view for project teams to show findings from the data to help make certain decisions.
- Automating a lot of my colleagues work with Python and if very restricted then just VBA macros in Excel and MSP. This did also include creating tools to gather data during workshops and converting the data for input into other systems.
- Brought Linux to the office with most team members now moving over to Linux with the peace of mind to know that though they do need to try solve their own problems, I can help if need be.
- Had to learn AWS and then implement an autoscaling and load balanced data center installation of a few Atlassian toolsets.
- Creating the architecture diagrams documentation needed for things like the above point.
- Having said that, also have ended up setting up all the Jira/Confluence etc. servers we use and have implemented so far whether cloud (Azure/AWS) or on prem and set up scripts to automate where possible.
- Implemented an automated workflow view in SharePoint based on SP list data and though in an ASPX page, primarily built in JS.
- Building test systems in PHP/JS with Laravel and Angular to help manage integration between systems. Having quite a time right looking into how to build middleware to connect between SOAP and REST API's, the trouble caused more by the systems and their reliance on frameworks we're trying to cut out of the picture.
- Working on BI and MI and training a team to help on the report creation so that I can do the fun creative stuff and then set them to work on the detail :)
Actually it seems safe to say that it seems that though I've finally moved into a dev office (beforehand being the only developer around) I seem to be the one they go to when a strategic solution is needed ASAP and the normal processes can't be followed (fun for someone with a CompSci degree and a number of project management courses under the belt... though I honestly do enjoy the challenges)
But I always end up Jack of all but master of, well hopefully some at least. let's not even get started on the tech related hobbies from circuit design and IoT to Andoid / iOS and game dev and enjoying a bit of pen testing to make sure we're all safe at work and at home.
As much as I don't like boxes, I'm interested to know if there is in fact a box for me? By the way, the above is just a snapshot of my last two years minus the project management work...2 -
Im working 6days, than I'm free 4 days. So 2-3 days from those 4, I would like to do some internship, traineeship or call whatever you want, at isp, data center or enterprise, to kick some real life network engineer experience. Basically I have 0 real life experience even I'm preparing to ccnp. Guys, I can't even find unpaid internship... When they hear that I have finished bachelor like 6 years ago, they just don't want to hear from me. I am deeply disappointed. Sometimes I feel that I won't have an it support job even with ccie... I mean I already feel more skilled than the complete IT crowd at the company where I'm working but no one cares. If you have some advice like where to go, please share with me...1

2019. I found a guy, CTO of our client. 50+ age. He teaches a lot to us. In development, I enjoy this year, because this year has more learning then last year.
I start work on 3 more languages, see more possiblities in IT, Avionics Softwares, Aviation systems.
This year, I also learn a lot about data center power distribution.
So this year was full of learning and new things in development and IT.2
