Yesterday the web site started logging an exception “A task was canceled” when making a http call using the .Net HTTPClient class (site calling a REST service).
Emails back n’ forth ..blaming the database…blaming the network..then a senior web developer blamed the logging (the system I’m responsible for).
Under the hood, the logger is sending the exception data to another REST service (which sends emails, generates reports etc.) which I had to quickly re-direct the discussion because if we’re seeing the exception email, the logging didn’t cause the exception, it’s just reporting it. Felt a little sad having to explain it to other IT professionals, but everyone seemed to agree and focused on the server resources.
Last night I get a call about the exceptions occurring again in much larger numbers (from 100 to over 5,000 within a few minutes). I log in, add myself to the large skype group chat going on just to catch the same senior web developer say …
“Here is the APM data that shows logging is causing the http tasks to get canceled.”
FRACK!
Me: “No, that data just shows the logging http traffic of the exception. The exception is occurring before any logging is executed. The task is either being canceled due to a network time out or IIS is running out of threads. The web site is failing to execute the http call to the REST service.”
Several other devs, DBAs, and network admins agree.
The errors only lasted a couple of minutes (exactly 2 minutes, which seemed odd), so everyone agrees to dig into the data further in the morning.
This morning I login to my computer to discover the error(s) occurred again at 6:20AM and an email from the senior web developer saying we (my mgr, her mgr, network admins, DBAs, etc) need to discuss changes to the logging system to prevent this problem from negatively affecting the customer experience...blah blah blah.
FRACKing female dog!
Good news is we never had the meeting. When the senior web dev manager came in, he cancelled the meeting.
Turned out to be a hiccup in a domain controller causing the servers to lose their connection to each other for 2 minutes (1-minute timeout, 1 minute to fully re-sync). The exact two-minute burst of errors explained (and proven via wireshark).
People and their petty office politics piss me off.2 -
Our web department was deploying a fairly large sales campaign (equivalent to a ‘Black Friday’ for us), and the day before, at 4:00PM, one of the devs emails us and asks “Hey, just a heads up, the main sales page takes almost 30 seconds to load. Any chance you could find out why? Thanks!”
We click the URL they sent, and sure enough, 30 seconds on the dot.
Our department manager almost fell out of his chair (a few ‘F’ bombs were thrown).
DBAs sit next door, so he shouts…
Mgr: ”Hey, did you know the new sales page is taking 30 seconds to open!?”
DBA: “Yea, but it’s not the database. Are you just now hearing about this? They have had performance problems for over week now. Our traces show it’s something on their end.”
Mgr: “-bleep- no!”
Mgr tries to get a hold of anyone …no one is answering the phone..so he leaves to find someone…anyone with authority.
4:15 he comes back..
Mgr: “-beep- All the web managers were in a meeting. I had to interrupt and ask if they knew about the performance problem.”
Me: “Oh crap. I assume they didn’t know or they wouldn’t be in a meeting.”
Mgr: “-bleep- no! No one knew. Apparently the only ones who knew were the 3 developers and the DBA!”
Me: “Uh…what exactly do they want us to do?”
Mgr: “The –bleep- if I know!”
Me: “Are there any load tests we could use for the staging servers? Maybe it’s only the developer servers.”
DBA: “No, just those 3 developers testing. They could reproduce the slowness on staging, so no need for the load tests.”
Mgr: “Oh my –bleep-ing God!”
4:30 ..one of the vice presidents comes into our area…
VP: “So, do we know what the problem is? John tells me you guys are fixing the problem.”
Mgr: “No, we just heard about the problem half hour ago. DBAs said the database side is fine and the traces look like the bottleneck is on web side of things.”
VP: “Hmm, no, John said the problem is the caching. Aren’t you responsible for that?”
Mgr: “Uh…um…yea, but I don’t think anyone knows what the problem is yet.”
VP: “Well, get the caching problem fixed as soon as possible. Our sales numbers this year hinge on the deployment tomorrow.”
- VP leaves -
Me: “I looked at the cache, it’s fine. Their traffic is barely a blip. How much do you want to bet they have a bug or a mistyped url in their javascript? A consistent 30 second load time is suspiciously indicative of a timeout somewhere.”
Mgr: “I was thinking the same thing. I’ll have networking run a trace.”
4:45 Networking run their trace, and sure enough, there was some relative path of ‘something’ pointing to a local resource not on development, it was waiting/timing out after 30 seconds. Fixed the path and page loaded instantaneously. Network admin walks over..
NetworkAdmin: “We had no idea they were having problems. If they told us last week, we could have identified the issue. Did anyone else think 30 second load time was a bit suspicious?”
4:50 VP walks in (“John” is the web team manager)..
VP: “John said the caching issue is fixed. Great job everyone.”
Mgr: “It wasn’t the caching, it was a mistyped resource or something in a javascript file.”
VP: “But the caching is fixed? Right? John said it was caching. Anyway, great job everyone. We’re going to have a great day tomorrow!”
VP leaves
NetworkAdmin: “Ouch…you feel that?”
Me: “Feel what?”
NetworkAdmin: “That bus John just threw us under.”
Mgr: “Yea, but I think John just saved 3 jobs. Remember that.”4 -
It fucking staggers me how many backend/devops-y people don't understand what a client side "request timeout" is, versus a server side one.
What does it mean:
The client was fed up with the servers bullshit, and decided to piss off and not wait around for the server to take forever to respond, because life's too short.
How not to solve/debug this issue:
- "I've checked the API request in tool xyz, and it works fine for me"
Congratulations, you've figured out how to call an API once, in isolation to the rest of the application, and without any excessive load. And using a different client to me, with a different configuration. Lets get back to actually looking at the issue shall we?
- "I only see HTTP 200's in the logs"
Yep, you probably will in most circumstances, because its the client complaining about it taking too long, not the server. If the server was telepathetic and knew what the client was thinking/doing at all times, we wouldn't have half of the errors we do.
- "Ah ok, I understand ... so how do I solve this?"
Your asking me? I don't fucking know, I didn't build the server! Put better logging in place and figure out why sometimes it takes forever.
Jesus fucking christ14 -
Alright, so the "big e-commerce" site have ranted about a few times decided to move their site to google, because the developers blame our server to be the issue.
Well, I wish I had a couple of beer to drink while I am enjoying the downtime, servercrashes, and timeout on the site now. I hope the devs eat their own shit, because they are. -
thought I'd check why I'm getting connection timeout on my app
I think the problem is me and not the code

Was in a middle of competitive coding trying to do some operation on a nxn matrix. Wrote this code.
for(i = 0; i < n; i++){
for(j = 0; j < n; i++){
.......
.......
}
}
Was waiting for the output, only to wait long enough for the coding platform to throw a timeout at my face and make me doubt my skills.2 -
Okay, Google. I can see why you want me to check those boxes with cars. And I'm also fine with you telling me to do it on a different picture if the first one didnt had any, just to check. But WHAT I AM FUCKING NOT OKAY WITH, IS ME SOLVING CAPTCHAS FOR 10 FUCKING MINUTES REPETEDLY SAYING PLEASE TRY AGAIN AND THEN TELLING ME THAT I AM NOT EVEN ABLE TO TRY AGAIN BECAUSE OF AN DETECTED ATTEMPT OF BOTTING? WHO ARE YOU? AN AI QUESTONING MY HUMAN IDENTITY? JUST BECAUSE IM USING LINUX YOU DECIDE TO GIVE ME ANOTHER NOTHERFUCKING BATCH OF STREET SIGNS? YOU CAN STICK THOSE STREET SIGNS UP YOUR ASS! FUCK OFF!
tl;dr: i got banned from solving recaptchas the second time this week. lets hope its just *another* timeout.8 -
Fuck strict corporate software policies, just let me WORK (╯°□°）╯︵ ┻━┻
When I came to this new workplace I was given a Windows laptop. And it came with a bunch of pre-installed corporate stuff and policies like automatic mandatory frequent driver and windows updates. Although I prefer linux, I thought, maybe I'll switch later, first let's see how everything works here, since on Windows I had all VPNs, certificates and other corpo stuff pre-configured out of the box. But imagine missing a standup, because of windows update in the morning. Or missing audio, because of drivers update in the middle of the meeting. And make it every week or so. Also, I couldn't not install my portable DAC drivers, because limited access, blah blah fuck me. And many other small things that I vaguely remember by now.
Later corpo decided to add a tracking plugin into a browser and that was it for me. Gladly, corpo policy allows using Linux (they have their own modified Ubuntu version), which has MUCH less of this crap. I mean, it's still somewhat managed by corpo (like I can't get rid of duplicated PPA, lol.. and sometimes I need to wait like 1-2 mins to login to my laptop because of login server timeout), but that's still better...
Linux, home, sweet home, I missed you <3
Also, I dodged the bullet. Win11 upgrade was a funny shit show to watch :D1 -

Our team was having a problem with very slow response times from a 3rd party web service they were contacting to get some device stats. No issues on the other end, but it had already been weeks. They ask me to take a look at it.
I take a few days, do a couple of benchmarks and tests and I isolate the section of code responsible. Turns out, the method they were calling would timeout if the device was offline. We ask the vendor, and they confirm this. They tell us to call methodX to check if it was up.
After having done that, lookup now only took seconds. They were annoyed that it wasn't documented but was just glad it was fixed.2 -
I've tried multithreading with php, wrote a simple script which checks a series of ip addresses and tries to ftp into them.
I've noticed that the script is running very slow, i checked everything, tested the db, tested my code, i've started to doubt, that my compilation of php was fucked up (btw i did that for the first time).
Then i've started to mesure the time of each db request, but the numbers didn't add up. Then it fucking hit me...
I fucking set the timeout for ftp_connect to 5 seconds, and that was causing the slowdown. I wasted two fucking coding sessions on finding that out.
What a fucking blind moron can I be, holy shit.4 -
I sometimes forget to close the tab to my bank's website. I flip back to it, hours, or even days later. As soon as the tab becomes active the "You'll be logged out in 60 second" timer starts ticking. Literally, days after I logged in, I can click "Stay logged in" and it works!
Their session timeout logic is all fucking Javascript based!? Don't they log out the session server-side at some point? How the fuck is my session still valid 2 days after initial login?5 -
I really wanna share this with you guys.
We have a couple of physical servers (yeah, I know) provided by a company owned by a friend of my boss. One of them, which I'll refer to as S1, hosted a couple of websites based on Drupal 7... Long story short, every php file got compromised after someone used a vulnerability within D7's core to inject malicious code. Whatver, wasn't a project of mine, and no one bothered to do anything about it... The client was even happy about not doing anything about it. We did stop making backups of such websites however, to avoid spreading the damage (right?). So, no one cared about this for months!
But last monday? The physical server was offline. I powered it on again via its web management interface... Dead after less than an hour. No backups. Oh well, I guess I couls keep powering it on to check what's wrong with it and attempt to fix it...
That's when I've learned how the web management interface works: power on/reboot requests prompted actual workers to reach the physical server and press the power on/reboot buttons.
That took a while to sink in. I mean, ok, theu are physical servers... But aren't they managed anyhow? They are just... Whatever. Rebooting over and over wasn't the solution, so I asked if they could move the HDD to another of our servers... The answer was it required to buy a "server installation" package. In short, we'd have had to buy a new physical server, or renew the subscription of one we already owned for 6 months.
So... I've literally spent the rest of the day bothering their emoloyeea to reboot S1, until I've reached the "daily reboot reauests limit" (which amounts to 3 reauests. seriously), whicj magically opened a support ticket where a random guy advised to stop using VNC as "the server was responsive" and offeres to help me with the command line.
Fiiine, I sort of appreciate it. My next message has been a kernel log which shows how the OS dying out was due to physical components becoming unavailable after a while, and how S1 lacked a VNC server, being accessible only via ssh. So, the daily reboot limit was removes for S1. Yay.
...What to do though? S1 was down, we had no backups, and asking for manual rebooting every time was slow as Hell. ....Then I went insane. I asked for 1 more reboot. su. crontab -e. */15 * * * * /sbin/shutdown -r +5. while true; do; rsync --timeout=20 --append S1:/stuff .; sleep 60; done.
It worked. We have now again access to 4 hacked, shitty Drupal 7 websites. My boss stopped shouting. I can get back to my own projects.
Apparently, those D7 websites got back online too, still with malicious php code within them. Well, not my problem (for now).
Meanwhile, S1 is still rebooting.3 -
Found this gem of a comment in a code base written 4 years back.
/*
Invoke <Service Base URL>/asset/v2/details/<SN> to get asset details
Feeling very bad to include this call, but we really need to use this !!!
This call is gonna take ~20s to respond. I've even increased the overall timeout of this module, just for this call !!!
So, if you are looking to debug any performance issue, I wish you jump directly here,
remove this call and just use master data management (MDM)
P.S: It is not that simple, as MDM and this asset DB (both asset masters) has differences in how the asset is defined :(
*/
Still trying to understand how to remove this costly time-consuming call and replace with an efficient one !!
And, of-course, the original author left 2 years back :(3 -
My company decided to reinvent the wheel by writing its own queue system instead of using the existing message queue service.
And it uses plain PHP with exec() to run the workers.
Where do we store the job? We use mongoDB which is already used in our existing projects. We can query the collection/table each time the queue service start, execute the jobs, and let it exit if there's no job anymore. Don't worry, systemd will start the queue service again once it exits.
How to monitor the workers? Yep, we use ps and grep to check if the worker's PID still exists in the OS.
What about error stack traces? Nice question, we redirect the stdout and stderr when exec()-ing into a file.
What about timeout? We don't need it, let's just assume no one is going to write while(true).
It works flawlessly! /s8 -
Problems with redis... timeout everywhere...
30k READs per minute.
Me : Ok, How much ram are we actually using in redis ?
Metrics : Average : 30 MB
Me ; 30 MB, sure ? not 30 GB ?
Metrics : Nop, 30 MB
Me : fuck you redis then, hey memory cache, are you there ?
Memory cache : Yep, but only for one instance.
Me ok. So from now on you Memory cache is used, and you redis, you just publish messages when key should be delete. Works for you two ?
Memeory cache and redis : Yep, but nothing out of box exists
Me : Fine... I'll code it my selkf witj blackjack and hookers.
Redis : Why do I exist ?2 -
Still dealing with the web department and their finger pointing after several thousand errors logged.
SeniorWebDev: “Looks like there were 250 database timeout errors at 11:02AM. DBAs might want to take a look.”
I look at the actual exceptions being logged (bulk of the over 1,600 logged errors)..
“Object reference not set to an instance of an object.”
Then I looked the email timestamp…11:00AM. We received the email notification *before* the database timeout errors occurred.
I gather some facts…when the exceptions started, when they ended, and used the stack trace to find the code not checking for null (maybe 10 minutes of junior dev detective work). Send the data to the ‘powers that be’ and carried on with my daily tasks.
I attached what I found (not the actual code, it was changed to protect the innocent)
Couple of hours later another WebDev replied…
WebDev: “These errors look like a database connectivity issue between the web site and the saleitem data service. Appears the logging framework doesn’t allow us to log any information about the database connection.”
FRACK!!...that Fracking lying piece of frack! Our team is responsible for the logging framework. I was typing up my response (having to calm down) then about a minute later the head DBA replies …
DBA: “Do you have any evidence of this? Our logs show no connectivity issues. The logging framework does have the ability to log an extensive amount of data regarding the database transaction. Database name, server, login, command text, and parameter values. Everything we need to troubleshoot. This is the link to the documentation …. If you implement the one line of code to gather the data, it will go a long way in helping us debug performance and connectivity issue. Thank you.”
DBA sends me a skype message “You’re welcome :)”
Ahh..nice to see someone else fed up with their lying bull...stuff.

Want to make someone's life a misery? Here's how.
Don't base your tech stack on any prior knowledge or what's relevant to the problem.
Instead design it around all the latest trends and badges you want to put on your resume because they're frequent key words on job postings.
Once your data goes in, you'll never get it out again. At best you'll be teased with little crumbs of data but never the whole.
I know, here's a genius idea, instead of putting data into a normal data base then using a cache, lets put it all into the cache and by the way it's a volatile cache.
Here's an idea. For something as simple as a single log lets make it use a queue that goes into a queue that goes into another queue that goes into another queue all of which are black boxes. No rhyme of reason, queues are all the rage.
Have you tried: Lets use a new fangled tangle, trust me it's safe, INSERT BIG NAME HERE uses it.
Finally it all gets flushed down into this subterranean cunt of a sewerage system and good luck getting it all out again. It's like hell except it's all shitty instead of all fiery.
All I want is to export one table, a simple log table with a few GB to CSV or heck whatever generic format it supports, that's it.
So I run the export table to file command and off it goes only less than a minute later for timeout commands to start piling up until it aborts. WTF. So then I set the most obvious timeout setting in the client, no change, then another timeout setting on the client, no change, then i try to put it in the client configuration file, no change, then I set the timeout on the export query, no change, then finally I bump the timeouts in the server config, no change, then I find someone has downloaded it from both tucows and apt, but they're using the tucows version so its real config is in /dev/database.xml (don't even ask). I increase that from seconds to a minute, it's still timing out after a minute.
In the end I have to make my own and this involves working out how to parse non-standard binary formatted data structures. It's the umpteenth time I have had to do this.
These aren't some no name solutions and it really terrifies me. All this is doing is taking some access logs, store them in one place then index by timestamp. These things are all meant to be blazing fast but grep is often faster. How the hell is such a trivial thing turned into a series of one nightmare after another? Things that should take a few minutes take days of screwing around. I don't have access logs any more because I can't access them anymore.
The terror of this isn't that it's so awful, it's that all the little kiddies doing all this jazz for the first time and using all these shit wipe buzzword driven approaches have no fucking clue it's not meant to be this difficult. I'm replacing entire tens of thousands to million line enterprise systems with a few hundred lines of code that's faster, more reliable and better in virtually every measurable way time and time again.
This is constant. It's not one offender, it's not one project, it's not one company, it's not one developer, it's the industry standard. It's all over open source software and all over dev shops. Everything is exponentially becoming more bloated and difficult than it needs to be. I'm seeing people pull up a hundred cloud instances for things that'll be happy at home with a few minutes to a week's optimisation efforts. Queries that are N*N and only take a few minutes to turn to LOG(N) but instead people renting out a fucking off huge ass SQL cluster instead that not only costs gobs of money but takes a ton of time maintaining and configuring which isn't going to be done right either.
I think most people are bullshitting when they say they have impostor syndrome but when the trend in technology is to make every fucking little trivial thing a thousand times more complex than it has to be I can see how they'd feel that way. There's so bloody much you need to do that you don't need to do these days that you either can't get anything done right or the smallest thing takes an age.
I have no idea why some people put up with some of these appliances. If you bought a dish washer that made washing dishes even harder than it was before you'd return it to the store.
Every time I see the terms enterprise, fast, big data, scalable, cloud or anything of the like I bang my head on the table. One of these days I'm going to lose my fucking tits.10 -
In fact I'm a sinful dev, so that I can't easily decide which one is worst. From indenting with tabs, or using nano instead of vim/emacs, to hardcoding database credentials on server, to many hacks and workarounds I use as actual "fixes" when the deadline is upon me and I've tried all I could. But it always led only to my own regret. For instance, my latest sin was that I prefered Debian over Arch and used proprietary graphic drivers to speed up my new setup. But ended up with a curse from St. Ignucius. (check my last rant)
But my worst sin probably goes to when I was "printf-debugging" some issue for a GSM controller on a raspberry pi. I forgot to remove one little print line and deployed the new "fixed" version. I didn't follow that project after that for like a month or so, when the client posted back the device and said that "it just doesn't work anymore". It seemed that raspbian didn't boot beacause the sd card was curroptted. I dd'ed through the card and I noticed that there are billions of lines of "DEBUG:: reading stream from 192.some.shitty.ip", took almost all over the 32G sdcard. Just as I suddenly remembered the cursed line I just added a month ago, I declared the sd card dead with no hesitation, dunce-commented the line (so the history would remember), implemented a time out for the thread containing it, setup a journald unit for my service and removed the redirection of process output to a log file, found a new sd card and installed everything again, and finally posted back the new "fix" to the client.
Moral: Never comfort yourself for the sins you have commited in the past kids, they certainly will come back to you. And also not to do any io especially write to a file on an SD card with ext fs, in a potentially infinite loop with no timeout.
P.S: I'd posted my last rant just before the new week rant last nigh. I really liked the St. Ignucius meme so decided to create a new one. He's very adorable :)

Had an internet/network outage and the web site started logging thousands of errors and I see they purposely created a custom exception class just to avoid/get around our standard logging+data gathering (on SqlExceptions, we gather+log all the necessary details to Splunk so our DBAs can troubleshoot the problem).
If we didn't already know what the problem was, WTF would anyone do with 'There was a SQL exception, Query'? OK, what was the exception? A timeout? A syntax error? Value out of range? What was the target server? Which database? Our web developers live in a different world. I don't understand em.

this fucking shit xamarin. I wish the ass who programed the xamarin vs2017 integration to go fuck off.
srsly, I just want to fucking code this fucking fucker VS2017 keep shitting all around me
first I was gonna install it. didn't install because no memory left. fair enough, my fault there.
cleaned 35 gbs.
finish installing VS, with xamarin. FIRST GOD DAMN TIME I create fucking project, 2 fucking errors and 3 warnings. I DIDN'T EVEN TYPE A COMMA.
ok, tried fucking it. it seems to be conflict between version of Android and xamarin forms. fucker you it shouldn't be like this. anyway.
tried downloading the updated Android version.
it failed at 80%! what error you ask? missing fucking space ok, fuck that thing is huge, ok, my fault again. uninstalled all programs I was not using, all projects I'm not current working on. more fucking 30GB free. tried again. ANDROID IS TOO FUVKING HUGE CAN'T INSTALL IN 30GB!!!
Ok. instead of updating android, gonna downgrade xamarin, can't downgrade. ok gonna remove and install an early version.
unistalled. CAN'T FIND XAMARIN DLLS.
I was like, fuck this project, gonna start a new one. ok, all seems fine, for some weird reason. Except no. I try adding a new page, ops, APPARENTLY VS2017 CAN'T LOAD A GODDAMN .XAML
Ok, I can create a .cs page. done, except now I get a fucking timeout error. fuck.
I search the internet for a workaround, see a guy saying I could manually add a .xaml + .cs by creating this files and then adding them to the proj file.
did it. I go again, everything seems fine. but now I can't freaking reference the damn page.
I'm fucking losing my mind here.
In the mean time I have to turn in this project at the end of the week AND I CAN'T FUCKING OPEN THE GOD DAMN FREKING PROJECT PROPERLY!
FUCK. MY. LIFE.
FUCK XAMARIM AS WELL
FUCK VISUAL STUDIO
FUCK MICROSOFT
FUCK THAT DAMN SSD
FUCK THAT BOSS WHO THINK THAT A 128GB SSD IS ENOUGH
FUCK IT ALL...15 -
>Be client
>Have an issue with incredibly slow webpage load time
>Blame memcache issues
So... I look into the problem. Yes, the page either loads up fast, or times out. So, into the logs I go. Webserver is fine (except the timeout), PHP though... Error log is fine (just notices), but slow log shows the issue is the database (of course... its always the database... ugh)
So, checking the database, there is one ugly query that seems to be an issue. 5 joins and a huge where condition.
So I run EXPLAIN on the query and... Proceed to bang my head against the wall.
OF COURSE ITS SLOW YOU FU******, NONE OF YOUR TABLES HAVE ANY INDEXES.
What do they expect when the database has to always go down the whole table and do everything in memory, until it runs out and has to dump it all on disk and work with it there.
Ugh... Some clients... -

The more I work with performance, the less I like generated queries (incl. ORM-driven generators).
Like this other team came to me complaining that some query takes >3minutes to execute (an OLTP qry) and the HTTP timeout is 60 seconds, so.... there's a problem.
Sure, a simple explain analyze suggests that some UIDPK index is queried repeatedly for ~1M times (the qry plan was generated for 300k expected invocations), each Index Scan lasts for 0.15ms. So there you go.. Ofc I'd really like to see more decimal zeroes, rather than just 0.15, but still..
Rewriting the query with a CTE cut down the execution time to pathetic 0.04sec (40ms) w/o any loops in the plan.
I suggest that change to the team and I am responded a big fat NO - they cannot make any query changes since they don't have any control on their queries
....
*sigh*
....
*sigh*
but down to 0.04sec from 3+ minutes....
*sigh*
alright, let's try to VACUUM ANALYZE, although I doubt this will be of any help. IDK what I'll do if that doesn't change the execution plan :/ Prolly suggest finding a DBA (which they won't, as the client has no € for a DBA).
All this because developers, the very people sho should have COMPLETE control over the product's code, have no control over the SQLs.
This sucks!27 -

Can someone please write a plugin that automatically translates bug tickets into startup-ese? It would make it very easy to present the most common offenders to higher management on quarterly reviews.
Example:
-
$< "screen A is all messed up"
$> "We are disrupting the establishment in screen A"
-
$< "API B is not responding, giving timeout errors"
$> "We are facing logistical challenges in API B"4 -
A time I (almost) screamed at co-worker?
Too many times to keep up with.
Majority of time its code like ..
try
{
using (var connection = new SqlConnection(connectionString))
{
// data access code that does stuff
}
catch (Exception e)
{
// Various ways of dealing with the error such as ..
Console.WriteLine("Here");
ShowMessage("An error occured.");
return false;
// or do nothing.
}
}
Range of excuses
- Users can't do anything about the error, so why do or show them anything?
- I'll fix the errors later
- Handling the errors were not in the end-user specification. If you want it, you'll have to perform a cost/benefit analysis, get the changes approved by the board in writing, placed in the project priority queue ...etc..etc
- I don't know.
- Users were tired of seeing database timeout errors, deadlocks, primary key violations, etc, so I fixed the problem.
On my tip of my tongue are rages of ..
"I'm going to trade you for a donkey, and shoot the donkey!"
or
"You are about as useful as a sack full of possum heads."
I haven't cast those stones (yet). I'll eventually run across my code that looks exactly like that.1 -
Why would anyone use CPU ticks for connection timeouts? Everytime that software is used in a new CPU it gets messed up. Why not just milliseconds?

So we have a web page which is really poorly written and times out after 100 seconds, so I suggest this is costing us money and is a really poor user experience. It needs some refactoring.

typeof rant === "Encouragement"
Never let your self down, try to be your own const in life that know his scope and traits well enough to construct a peacefull life without any uncatched exceptions. Also try to return something to the public, keeping your magic pointers to your private makes it hard to review your glorious source of thoughts. And if it is getting hard try to REST a bit and git some timeout.

Well, being the only one in the house who can really solve computer problems:
We have a home nas in our network for filestorage and since a few weeks, we couldn't acces the device through windows explorer, so today I went on a exploration... First I tried the nas in a seperate different network, and it worked immediatly! oke great, try it in our main network again. And 'ofcours' it's not visible. So I go to the router webpage, and the page of our router just really sucks! So it was quite hard to find out if the NAS was attached or not, ad if so, under which IP. Finally found that, tried to connect to the webpage of the NAS, but got a timeout, ping would timeout too! I thought that that might have someting to do with that the NAS would connect via static IP. So I changed that to a dynamic IP, and I could atleast get to the website. After that I could try all the services and all of them worked perfectly, except for samba... And samba is the only service we actually use, so after that I thought that the device not showing up in network view in explorer had something to do with that the nas wouldn't show me a hostname in the router. So I tried to fix that, after an hour of trying to get the hostname to showup in the router, I just thought that I might try to connect to the nas via the IP. So I found via SO that I could just use //192.168.0.104 and I got into the samba server. So I guess that it was actually working all along 😒. After that I didn't want to bother to work with the hostnames, so I just gave the NAS a fixed IP, made a few shortcuts for my housemates and now it all works again.. For now at least...3 -
Auto tuning for Azure SQL databases is cool but :
DON’T allow it to automatically drop indexes ! (My bad, I should’ve tested that before)
It dropped one of the most used indexes in the DB. Yep, just like that. 150+ timeout exceptions and customers going crazy4 -
I once accidentally pranked myself with a simple batch file that opened explorer windows on .25 second intervals.
The best part is that I was testing the timeout function and thought opening an explorer window would be the best way to gauge its success.1 -

my 4TB Seagate HDD is failing in a very strange way:
I noticed an issue where my PC would just outright hang for a minute or two occasionally when swapping to the 4TB HDD. When I look at logs, when it hangs, the 4TB HDD times out but then on a retry IMMEDIATELY reads whatever sector just fine. In fact, it reads fine constantly for a few days until the same sector has an issue. So, the timeout is a remap, then? No, as the spare sector and bad sector counts in the SMART info don't change. It doesn't even change how many read errors or anything it's had. Strange, but let's test it with Seatools to be sure.
Tests go as follows:
- Short: pass
- Short: pass
- Long: seatools immediately crashes. Reopening seatools, it pulled a serial of all zeroes... okay....?
- Long: seatools immediately crashes. Seatools gets the right serial on reopen.
- Long: pass
- Long: fail
- Long: pass
- Long: seatools immediately crashes. All zero serial again.
i have no idea what's happening14 -

So I was setting up ELK (Elasticsearch, Logstash and Kibana) all in one EC2 on AWS today for demo purposes. I had everything prepared. Elastic IP, correct security group rules, etc.
I figured I would just do quick test before writing filters and templates if I can access Kibana. So I started service for it and tried to open it with Chrome.
Timeout.
Checked config file. Compared it to documentation. Seemed good but changed some things just for sake of change. Restarted service.
Timeout.
Reverted changes I've made in config. Restarted service. Curl on localhost. It work... OK. 😐
It took me half an hour but finally I figured it out after I took my phone and opened it from there. It was working from the beginning. Stupid company network was for some reason blocking this connection. Fuck! 😡And I was restarting that poor service like crazy trying to fix something that wasn't broken. -
The moment you realize that you have successfully beaten reality with your unit-tests...
There are unit-tests for ...
... the api returning a 408 Http StatusCode when an internal request times out.
... the react app take this status-code and fires an action to display a specific error message for the user.
Every bit of code runs just fine.
Deploy this hell of an app on the server. Dandy Doodle.
Do a smoketest of the new feature.
FAIL!
Chrome starts to crumble during runtime. The api Request freezes.
Firefox takes the 408 api response but fails to interpret it in react app.
So I began to wonder, what the hell is going on.
Actually I recognized that I had the glorious idea to return a clientside error code in a serverside api response.
Glorious stupidity :/
Finally I fixed the whole thingy by returning an 504 (Gateway timeout) instead of 408 (Clientside timeout)
Cheers!2 -
I would like to call out the moron who decided to control docker through HTTP when the maximum time the server can take to finish the task is longer than the HTTP timeout.
If you expect things might time out, you don't use a HTTP request. You use a resource and poll it, or Websockets, or possibly SSE.
Shoehorning your API into a frame that obviously doesn't fit doesn't help anyone. Just admit that you don't know what HTTP is and use a regular TCP socket with regular pings.2 -
I don't know why I'm doing this but when I go to websites that aren't mine and found that there's a bug in their site or system, I kinda happily report these bugs and issues to their email with screenshots, findings and steps to reproduce the bug.
Just recently, I just went to a site and found a peculiar timeout error, eventhough it was less than a second to respond back. Only to find that there was an undefined JavaScript variable in their code.
Is there a bug bounty for fixing code?6 -

Trying to setup a ltsp server for fun. Neve done server things before.
The server and the thin client are in VMs. So I start, install openssh, and them when I try to ssh... WHY CAN’T I FUCKING CONNECT, I CHECKED THE IP WITH IFCONFIG, oh shit, forgot to configure the vm network... so ssh works! Then I setup dhcp (I really don’t know what I’m doing, just following the tutorial), the ltsp configs thing, build the client image and then, I HAVE NO FUCKING INTERNET CONNECTION. Continues, boot up the thin client... WHY CAN’T YPU FUCKING FIND THE SERVER!! Then I realise the vm is not an ubuntu one, so delete it and make a new one... WHY DOES IT STILL DOESN’T WORK!!!!!! Oh wait forgot to connect to the network! Goes to put the network adaptor, and: wait! I don’t need NAT! So I replace the NAT by the correct network, and: Wait it lets me choose the weird thingy intel/pce thingy, oh I remember now! It said we needed the “...III FAST...”! Activate it and... IT WORKS ! !!!! CONNECTS TO THE SERVER!!! GOT THE DHCP!!! WAIT!!!!! What is THAT 🤬 TFTP LOADING THING!!!:

I think another intriguing job asides programming is engineering (*for some*). A week has past and I've been on the hike assisting my beloved brother on his contracted engineering job while I am less occupied. The job is based on 🗼Tower analysis and It's quite risky as you'd have to climb up to 56 meters high just to take readings of antennas, and fix some other stuffs. The only thing I find intriguing about this job is his love for it, funny enough he also thinks I love the job too and I guess I'm guilty for his thoughts (*Sorry bro, I love the job for you not me*).
With my little experience so far on my *new brotherly job* I noticed the most hectic task isn't going up and down the tower taking readings but at the end of all operations, he'll have to gather the values and snapshots he took while on the tower to prepare reports on msword & excel for the other buttwags at the office (or home I guess)
then archive and sends via mail. Seeing this lengthy process I was forced to ask why he wasn't using any reporting tool like Jotforms or any other equivalent and I was willing to look up some recommendations for him, his reply was: "I'm already used to this form of reporting, its what I was trained with and what the company provided, nevertheless a friend of mine suggested something of such weeks back but I would have to pay monthly fee for its usage which is quite on the high side and I don't think I'd prefer that."
Sounds convincing but not enough, okay here is another deal: You use an android phone right? and at my office we work on system automation (*basically does not know what I do for a living probably thinks I'm a hacker the illegal one*), how about i design you an android app for you to capture the tower data and a PC software for you to auto generate the msword & excel reports, I can get this ready for you in less than 5 nights (*I've got less task on my desk, and was willing to take the timeout to prepare the solution that he needed, all I needed to hear for a kick start was an "Okay" just to be sure he wants it*) I suggested and re-assured but up to this point he still declined my offer and is willing to stick with his current reporting pattern (*Me died*).1 -
FUCK APPLICATION LEVEL FIREWALLS!
So i cam online today, thought already lets open the shitty outlook webmail client. Holy crap .... thats way to much mails. Many of them are missed teams messages. So i open up teams and holy crap. Like every third dev in my company send me a message screaming "gitab is not working!!!".
Yesterday i updated it so imediately get in panic mode - what the shitty hack have i done?!
So yeah gitlab seems to be working just fine, everything is speedy and responsive, so i call one of my fellow devs and ask him whats wrong? And he is like oh yeah there comes a ldap error saying timeout or something.
I try to login with active directory. Works like a charm. Try another account, same problem?!
Google the problem, search gitlab tickets. Nope there is no open bug or sth. like this.
So alright lets call the network guy. "Yo, can you check if there is something ldap-like getting blocked to the gitlab server?" - He is like oh yeah damn like almost every damn request is getting blocked. Ah wait, there was an firewall update yesterday too. Yeah ldap is no longer ldap. BLOCK THAT SHIT!
After 10 minutes of figuring out what shitty type is detected by the firewall and what needs to be whitelisted to make it fucking work again it seems to work.
But ha no, there is another update rolling on, so same shit like 15 minutes later.
Now it seems to work and i have to inform every damn fcking developer that it works again. And yeah alright you sent a mail, but fuck it, i will call you though! So yeah just answering calls, mails and chat messages. Like why the fuck cant you read your mails like a damn normal person?!1 -

Nice. I have now wasted about 8 hours or so debugging to find out why my (fully functional) program wouldn't receive messages (from an FTP server through a socket). It just received an timeout from the server after 300 seconds. Then I discovered that my messages didn't include '\r\n' in the end.

Spent about 5 hours trying to figure out why php-fpm 7.2 was sending a timeout to nginx inside a CentOS 7 container. In the end I couldn't figure it out, downgraded to PHP 7.1 and then everything start working fine.

Hopefully I can move away from using CentOS for containers soon since the base image is also quite fat.

Should i push some common sense to some people in the company ????
Both our QA, customer QA, our project manager and their project manager agreed to set a timeout of 400 ms after press interaction to buttons, images or list items, just to show the ripple and fade effects to the user.
I am implementing it, and the application obviously has become much sluggish. They will blame me when they actually see this, because 75 or 100 ms is pretty enough to show any effect and make the app fast enough.
They will want me to change it afterwards, i am completely sure. I wish i was there to emit some common sense to those homo not sapiens.3 -

I hate the elasticsearch backup api.
From beginning to end it's an painful experience.
I try to explain it, but I don't think I will be able to cover it all.
The core concept is:
- repository (storage for snapshots)
- snapshots (actual backup)
The first design flaw is that every backup in an repository is incremental. ES creates an incremental filesystem tree.
Some reasons why this is a bad idea:
- deletion of (older) backups is slow, as newer backups need to be checked for integrity
- you simply have to trust ES that it does the right thing (given the bugs it has... It seems like a very bad idea TM)
- you have no possibility of verification of snapshots
Workaround... Create many repositories as each new repository forces an full backup.........
The second thing: ES scales. Many nodes / es instances form a cluster.
Usually backup APIs incorporate these in their design. ES does not.
If an index spans 12 nodes and u use an network storage, yes: a maximum of 12 nodes will open an eg NFS connection and start backuping.
It might sound not so bad with 12 nodes and one index...
But it get's pretty bad with 100s of indexes and several dozen nodes...
And there is no real limiting in ES. You can plug a few holes, but all in all, when you don't plan carefully your backups, you'll get a pretty f*cked up network congestion.
So traffic shaping must be manually added. Yay...
The last thing is the API itself.
It's a... very fragile thing.
Especially in older ES releases, the documentation is like handing you a flex instead of toilet paper for a wipe.
Documentation != API != Reality.
Especially the fault handling left me more than once speechless...
Eg:
/_snapshot/storage/backup
gives you a state PARTIAL
/_snapshot/storage/backup/_status
gives you a state SUCCESS
Why? The first one is blocking and refers to the backup status itself. The second one shouldn't be blocking and refers to the backup operation.
And yes. The backup operation state is SUCCESS, while the backup state might be PARTIAL (hence no full backup was made, there were errors).
So we have now an additional API that we query that then wraps the API of elasticsearch. With all these shiny scary workarounds like polling, since some APIs are blocking which might lead to a gateway timeout...
Gateway timeout? Yes. Since some operations can run a LONG (multiple hours) time and you don't want to have a ton of open connections hogging resources... You let the loadbalancer kill it. Most operations simply run in ES in the background, while the connection was killed.
So much joy and fun, isn't it?
Now add the latest SMR scandal and a few faulty (as in SMR instead of CMD) hdds in a hundred terabyte ZFS pool and you'll get my frustration level.
PS: The cluster has several dozen terabyte and a lot od nodes. If you have good advice, you're welcome - but please think carefully about this fact.
I might have accidentially vaporized people sending me links with solutions that don't work on large scale TM.2 -
I've been working with Node and Typescript for a while now, and I wrote a wide array of very general utility functions. Examples include:
- Array.filter but you also get the residue array, it can also leave holes in both arrays if you want to join them later
- Array zipping and unzipping to and from tuples (especially valuable when you're manipulating the prop set with Object.entries() in a HOC
- Array maximum selection, with an optional mapper
- Cancelable promises, lazy promises, a promise that resolves when a given function on an object is called (excellent for DOM events), a timeout promise.
- A typed event with both immediate and microtask listeners depending on whether you need state guarantees (this idea I took from a Github gist and upgraded it)
I want to put them on NPM so I don't have to write them and their tests again, and so that if I ever think of an improvement it's easier to propagate it. Do you think I should release them as tiny individual packages which would be nice from a versioning standpoint, or should I make them into a compilation which would be a lot less work for me (and therefore would probably result in better documentation and more tests)?4 -
A CASE AGAINST BLUE PRISM
Let's review one of the worst weeks I had with Blue Prism
Monday: Yay! Solved one of the problems we've been carrying around for a week before.
One of the robots suddenly became slow. Like, REAL slow. A process that would take 3 minutes per record now takes 45, and that broke apart all the following schedule.
There were no updates on the application server, the production machine, the robot, it just became slow. And not always slow; a process manually run from console room would work, a process in debug room would work, it's just the scheduled part that caused problems.
It turned out, BP didn't seem to like that particular combination of schedulation + process + machine. Moving the process to a different machine seemingly fixed that. IDK why.
Tuesday: One of our processes waits for a code to appear in the page, and when that happens, it memorizes this code. However, now it is always returning blank. Worked for months, now it breaks every single time.
After half a day of debugging a bug which DIDN'T HAPPEN IN DEBUG MODE YET AGAIN, at 11pm I decided to just place a nonsensical timeout in page before reading and call it a day.
WEDNESDAY: a scheduled process didn't start. "No sessions created". Thanks Blue Prism, very cool.
THURSTAY: This time, schedulation did start, but the process is "waiting". As in: it's 9:30 am, the process has been stuck in the same step since 6:00 am. Turns out, it blocked during a navigate stage; you need to send a string to clipboard using the standard BP action for that, then paste and click "enter", but for some reason the standard BP object sent "ORRCO" instead of "ORRICO" to clipboard, which obviously returned no results and then... the process just didn't feel like doing things anymore. No errors, no logs, nothing: just sitting on its ass. Because fuck you that's why.
Friday: another process uses a very moderate amount of scripts to work. Nothing really fancy, just a couple of lines of code to place in page some IDs and selector to help BP do its thing, otherwise selecting these elements would be a nightmare.
But
Failed while invoking javascript method:Exception from HRESULT: 0x80020101-> at mshtml.HTMLWindow2Class.IHTMLWindow2_execScript(String code, String language)
The same script -it's not dynamically generated-worked yesterday, the day before and the day after. But sometimes it will not. Why? The answer, my friend, is blowin'' in the wind -
Trying to delete a bunch of posts from my FB timeline. Why the fuck is there a 50 post limit? and why the hell do they have a 30s timeout, if their API is too slow to do it in sufficient time?5

Wanted to try a new alerting based on a new Prometheus metric we added. To trigger an alert we killed the dev stage db of the service. Alert didn't get triggered. The reason was that the metrics endpoint suddenly needs exactly 60s for a response if the db is killed and prometheus timeout is 20s.
And to top it off, this behavior happens for each service we developed (that has a db) .
Well at least the new alerting already helped find a bug.2 -
Within some real time communications app, my colleague, puts breakpoints to inspect. While inspecting the other party of comms goes into timeout. I advised to use print-breakpoints (vs 2015). So he stops the program and looks for the variable of interest then hit Run as fast as he can.

PHP dev help/advice needed!
We have problems with mysql. Still stuck with mariaDB, I'm using indexes (correct ones) and we have problems with scaling. we have a few tables with over 100mil rows, 1 of them is being read every morning with a subselect that counts unique rows, and fails every time because of timeout/lock, the temp table size was increased and helped for a little while but as time goes on the table grows and the problem reappears. I'm reading from a slave server that was purposely created for read only, yet we still have problems. We're using managed dedicated servers for out hosting and they aren't willing to optimise the database configs for our needs. What are the easiest options for scaling at this point? Going fully dedicated server and perconaDB? NOsql? Sharding the server? Anyone got any good blogposts or something to read about this? your own experience?11 -
Could somebody please help me understand why the fucking hell does JS (I am talking about node.js, so backend) use 32bit integers in setTimeout and setInterval? I mean, I understand most of the choices regarding the language (I have chosen programming languages design and principles for my studies) and I am happily using it for almost 4 years. But I came across an occasion that I had to use big numbers in those functions and it took me a lot of time to figure out why the fuck my code was not working as it was supposed to.
If anyone has a good reason please elaborate. In the meantime I'll go punch some shit to calm down.10 -
So I'm in a situation where I have to send a big set of data (from a numerous set of profile), but I can't because the framework used has been thought for sending few data (from an only profile) and then get a timeout.
I should take it as a challenge, a hard one but a challenge. Gonna be funny (and tiring too I guess)1 -
Third day of working on my recruitment task, and I'm starting to get pissed. I'm applying for Junior JS developer (suprised that they even picked me, I had 1 JS project in my resume, rest was Java). The task seemed simple, create website with autocomplete field which gets 10 cities with most polluted air from given country and get cities deacription from Wikipedia. But hell no. First, the air quality API that they told me to use sucks horse dick. Like seriousy, you can get a fucking timeout while fetching data, because as author explained, someone decided to make 2 fucking queries per request, one to count all possible results, and then the second one for actual data. Like, WTF, why would you do that. After I got that shit to work from time to time, it was time to Wikipedia API. And the shitshow starts again. Because it turns out that you can't filter the results based on the category. Which means that if the city has the same name as river or some fucking guy doing sports, I won't get the fucking description, because it will simply return info, that there are more more that 1 result. At this point, I'm so fucking pissed, I am barely keeping it together. I want to work at this company, because the pay is great, there are a lot of opportunities and shot, but god dammit, if I finish this task, I'm getting drunk for 3 days straight.
EDIT: even author of the air quality API says that it is not a good fit for given task...4 -
On https://reactjs.org/docs/... it is declared that useEffect runs after render is done.
However... if you put into useEffect an expensive calculation or operation e.g. "add +1 to x billion times", it will get stuck after updating the data, but before the re-render is done.
This leads to inconsistency between the DOM and the state which I believe is a foundational point of react. Moreover, the statement that "useEffect runs after render" is false.
See also: https://stackoverflow.com/questions...
The solution is to add a timeout to that expensive operation, e.g. 50 ms so the re-render can finish itself.
The integrity of my belief in react has received a shrapnel today. Argh :D Guys, how this can be? It seems that useEffect is not being run after re-render.13 -

I'm planning to go up the One World Observatory tmr morning but not sure which ticket to buy, particularly the IPAD option with streaming video. It says you can watch them later although it also expires apparently. So I'm wondering it worth it... (I'm also thinking since it's streaming and I can share it with anyone, it means I can probably download it too... the techie way).
Also can I bring a USB charger? My plan is to sorta just sit up there in the morning. Then head to Timeout Market for lunch-dinner.3 -

This had just happened, I was trying to increase the default timeout of an nginx running in a container for a proxy pass and always got a 504-gateway timeout response. I was setting proxy_connect_timeout, proxy_send_timeout, proxy_read_timeout, send_timeout, keepalive_timeout, etc. and nothing worked, after two hours of adding and removing lines of configuration (and waiting 1 minute for every time I tried a request), then I realized I have a local nginx for redirect server names to local ports (the container), that nginx was the one that actually responds with the 504 error, after that I tried a request with the port of the container ALL WORKED!!!!

TL;DR I have to bump a Redis cluster from t3.medium to m6g.large just to get enough network bandwidth even though I have no need of the extra memory.
Debugged an interesting issue today.
I am adding Elasticache to a project to reduce strain on the single node postgres DB.
Deployed a Redis replication group with 2 shards, with multi-AZ replication for resilience.
Everything was going well. We arent caching that much atm so was barely using 100Mb of memory.
Suddenly, when our US region comes online, latency skyrockets and the logs are full of Jedis timeout errors.
Still no issue with memory or node CPU.
The cause? Arbitrary network bandwidth throttling by AWS. The app currently processes about 3,000 requests per second so we were exceeding Amazons random ass allowances which arent documented anywhere.1 -
Exhausting all other options is a precondition for making a timeout heavily dependent on the system setup configurable according to the VSCode team. They advised us to not use NVM, to buy faster computers, to move time-consuming processes from .bashrc into .profile, before allowing us to manually make VSCode wait a bit longer. Microsoft attitude

I got situation here,
I am getting 524 error from cloud fare. I sent some data using AJAX, process it and then return the result. Since the data is large and have some SQL manipulation on it so it take a lot of time. I put the process in back end. But still even for 10k records it took 4-5 minutes to process, Issue is everything works fine but since cloud fare response time is 1-2 minute so it through 524 error (as it does not getting any response within its time frame). How I am suppose to tackle this. May be using job scheduler now ? My client simply refuse to send small data. My Friend is suggesting don't use ajax, simply reload the page. But again data is too much so page loading will also through 524 error. Kindaa stuck here. Any idea/suggestion how I can proceed.
Language I am using PHP. Database, MySQL and SQL.
Hmm Here is some more explanation

Pff today I start 400 threads in python initialized in a for loop, one thread per record, each record initialize a heavy process, Memory Limit Exceeded, I'm frustrated with this shit!
How to run 400 records doing a heavy task preventing the CPU to close the task executed by timeout limit exceeded, or how to run multiple threads to end before reach timeout limit each task without exceeding the memory limit.

Storytime - The Prometheus tales - Part III (I think..).
Updated the node definitions on the old node today, just to keep it up to date. nothing fancy.
I went to the new node and and checked the setup again. I already had roughly 120 node definitions onboard for testing purposes.
so all firewalls should have been configured the right way, so that the wee one might celebrate the marriage with the rest of the gang finally.. and then went with "puppet YOLO" on the new node. added every fkn node definition to the new setup.
every node turned out just to be fine.
except for 137 little InstanceDown alerts (out of 600+).
it's a good thing, that the little fella can send mails to me, myself and I only for the time being.
so debugging. again. but at least it's not a problem related to prometheus itself, because the connections end with a timeout on the related nodes. should be more like a firewall fubar.
we will see.5 -
Is there a goddamn way of making a setTimeOut() call in nodejs work like a manualresetevent with a timeout in c# ?

Dude ist sysadmin at server Pool hosting our app for the client.
Client: something minor is not working.
Dude: Let me just restart app, works at my windows laptop everytime or whatever.
*restarts app, hangs on entrypoint*
Dude: Dear client it's brocken.
Clients: *calls us in panic.*
Horus: Dear dude, when it hangs on startup consider to download an update because we fixed some issues with in theis area recently. Also maybe enlarge the docker compose timeout.
Dude: Still does not start up.
Horus: ok just call me on this Zoom link, then we can debug together.
Dude:...
Dude:...
Dude:...
Dude: oh i just saw it did startup mean while, it just took some time.
Fuck you dude, and your impatience!1 -

Play PUBG in different way.
Automate (WASD) with codes and timeOut.
or
Play it with Neurosky headband.
or
play it in virtual box in another virtual box
or even better
play it in Android Emulator.

- Have the app running perfectly on heroku.
- App does some serious calculations which, depending on amount of data, takes a long time to process
- Heroku timesout after request takes longer than 30 secs...
- Need to move from heroku to aws... No devops experience...
- Damn... 🙃
Any suggestions? The procedure cannot be put into a worker queue so thats out of the equation.2 -
The application I work on starts throwing timeout errors for about every third user. Lead developer cannot figure out what happened. DBA is out of town and cannot be reached. I do a quick Google search and run the stored procedure sp_updatestats. Timeouts stop and there is a big performance boost on the application. Everyone congratulates me on fixing the problem, and now I'm reading up on MS SQL Server Statistics and wondering about what other magical tools everyone else knows about that me and my team are clueless on...
