Developer (master's degree, -bleeping- smart guy, no kidding) was bragging on how he made a piece of code 3x faster (with the usual pinch that the original dev was incompetent) and spent nearly 6 weeks working on it (wrote his own parallel-foreach library because Microsoft's parallel library was "too slow").
I was the original dev and he didn't know I had my own performance counters where I broke down each stack (database access, network I/O, and the code logic).
Average time was around 5ms (yes milliseconds) and worst case was around 10 seconds. His '3x improvement' was based on the worst test case, which improved by about a second. Showed our boss my graph (laughed out loud, said 'WTF', other curse words) and the dev hasn't spoken to me in weeks (I say 'hi' in the hall and he keeps walking)
Take that master's degree and high IQ and shove it.

"Oh, he is asking that much money for this website? I will create that for only $250 with WordPress. He is just trying to use you"

You fucking wanker. What you don't understand is that you are pushing the companies to a fucking black hole that they won't be able to recover from.

He shows an example of a website which takes 30 sec to load. It's full of hundreds of dreadful plugins. He chose the shittiest stock pictures to make it look "pretty".

When I point out his fucking shite website takes this long to load, he says if the company wants to make the website fast, they will need buy the premium plan of CloudFlare. WHAT THE FUCK are you even talking about?

Not only that, the example website, doesn't even have any SSL. He is saying that the other company didn't want to pay for the SSL. Ever heard of fucking StartSSL or LetsEncrypt?

It's people like you who is responsible for making half of the web an insecure, slow, low-performance space which is prone to hacking.

WordPress was made for blogging. KEEP IT THAT WAY. Stop trying to make your high-performance CMS or eCommerce website with this shite.

@Devintrix , congrats and happy lifes with your wife. this joke is for you :)

Dear Tech Support:

Last year I upgraded from Girlfriend 7.0 to Wife 1.0 and noticed that the new program began running unexpected child processing that took up a lot of space and valuable resources.

In addition, Wife 1.0 installs itself into all other programs and launches during system initialization, where it monitors all other system activity. Applications such as PokerNight 10.3, Drunken Boys Night 2.5 and Monday Night football 5.0 no longer run, crashing the system whenever selected.

I cannot seem to keep Wife 1.0 in the background while attempting to run some of my other favorite applications. I am thinking about going back to Girlfriend 7.0, but un-install does not work on this program.

Can you help me please?

Thanks,

Joe

Dear Joe:

This is a very common problem men complain about but is mostly due to a primary misconception. Many people upgrade from Girlfriend 7.0 to Wife 1.0 with the idea that Wife 1.0 is merely a “UTILITIES & ENTERTAINMENT” program. Wife 1.0 is an OPERATING SYSTEM and designed by its creator to run everything.

It is unlikely you would be able to purge Wife 1.0 and still convert back to Girlfriend 7.0. Hidden operating files within your system would cause Girlfriend 7.0 to emulate Wife 1.0 so nothing is gained.

It is impossible to un-install, delete, or purge the program files from the system once installed. You cannot go back to Girlfriend 7.0 because Wife 1.0 is not designed to do this. Some have tried to install Girlfriend 8.0 or Wife 2.0 but end up with more problems than the original system.

I recommend you keep Wife 1.0 and just deal with the situation. Having Wife 1.0 installed myself, I might also suggest you read the entire section regarding General Partnership Faults (GPFs). You must assume all responsibility for faults and problems that might occur, regardless of their cause. The best course of action will be to enter the command C:\APOLOGIZE. The system will run smoothly as long as you take the blame for all the GPFs.

Wife 1.0 is a great program, but very high maintenance. Consider buying additional software to improve the performance of Wife 1.0. I recommend Flowers 2.1, Jewelry 2.2, and Chocolates 5.0.

Do not, under any circumstances, install Secretary With Short Skirt 3.3. This is not a supported application for Wife 1.0 and is likely to cause irreversible damage to the operating system.

Best of luck,
Tech Support

Recipe for a Great Programmer:

Ingredients:
-Books for a computer science curriculum from a top university
-Computer
-Headphones
-Internet
-Stress ball
-Pillow
-Lighter fluid
-Food

Directions:

1. Cover computer science books with lighter fluid
2. Light books on fire
3. Use flames to cook an energy-rich meal for the thousands of hours ahead
4. Pick an IDE
5. Choose a project beyond current capabilities. Good ways to push boundaries:
- Unfamiliar domain (e.g. large scale data processing, UI programming, high performance computing, games)
- Exotic programming language
- Larger in scope than any project before
6. Shut up about your IDE
7. Attempt to build
8. Stop procrastinating on Hacker News
9. Re-attempt to build
10. Squeeze stress ball and scream into pillow as necessary to keep sanity
When stuck:
- Paste stack traces into Google
- Find appropriate mailing list to get guidance
- Realize that real learning happens when you are stuck, uncomfortable, and/or frustrated
- Seek out books, classes, or other resources AFTER you have a good understanding of your deficiencies
11. Repeat #4 to #10 for at least 10 years
12. Results guaranteed! (to the same extent static types guarantee bug-free programs)

Dev: Hey, do we have a Google cloud machine running?
Me: No we have AWS remember?

Dev: Okay..
Me: Why do you want a gCloud?

Dev: I had this large stack of files and want to put them somewhere, off of my laptop. I just feel comfortable using Google than AWS.
Me: Umm.. there is Dropbox for that sort of stuff. Not high performance servers running our services.

Dev: ...
Dev: (After a moment) Yeah, why didn't I think of that? :/

Me: Seriously???

I think he forgot to have breakfast today.

Someone at work trying to impress me: I recently got a really nice PC! It runs Microsoft 10 and has an i5 graphics card and a high performance case!

Me:

Sooo, in my 5 years of high school, I had 5 different IT teachers...
Now, in Italy Highschool goes from 14 to 19 years old, I started programming some days after becoming 13, and "programming" classes begin on the third year, so I had quite a headstart on my classmates...

Now, for the third year, I had an awesome teacher, he noticed I was ahead and... Bored, so he gave me some extra stuff to study, he's the only teacher I've learnt anything from, it was awesome, very stingy with grades, but getting a perfect score with him was so satisfying.

Fourth year, the new guy was old, very old, at least 70, his lessons were just him talking about how programming was when he was young.

But then... During the second half of the fourth year I changed class due to bullying under a teacher's advice, and HE happened...

My new IT teacher, one of the most ignorant, awful people I ever met...
He's literally the reason I only went back to that school once, because another teacher needed help with a course...
One day I made the HUGE mistake to say that his "while(i <10000000000000);" wasn't very efficient for making a delay, because it didn't free the CPU, and since then:
- I never got more than 7 out of 10 at his tests
- He insulted me in front of the whole class
- He sabotaged the oral part of my final exam, shouting that he hated D'Annunzio when he saw he was in the literature part of my thesis (needed him to connect to WW2, and the Memex, that then allowed me to start talking about PCs and programming, my thesis was about the influence of lisp on modern programming languages), loudly chatting with other teachers when I was trying to keep calm (a teacher who knows me quite well, and was there to see my "performance" thought I was going to snap at some point), distracting the english teacher when I was exposing the english part of my thesis and pressuring the commission to give me 99 instead of 100 out of 100

So yeah, he almost made me hate the only thing I'm good at, undervaluing my work and my skills, undervaluing and humiliating me as a person, and I think that if I meet him again I might spit on his face...

So yeah, my biggest "programmer enemy" was a person that then did everything in his power to make my last year and a half of highschool hell

Now I can gladly say that with the help of my tutoring, some of my university colleagues are starting to appreciate programming, and my engineer friends ask for my help when they need advices about their code, and it's giving me motivation to keep doing it and becoming a better programmer to keep up with their expectations

I have a laptop which I bought for the sole purpose of gaming and I bought a hell lot of games off steam to startup.

But the problem here is I have to run those games on Windows (nvidia graphics card) and I only have a primary hdd and no ssd. Even though the ram and processor is up to speed due to high I/O on disk, I am not able to get a good performance out of it. To top it off random Windows processes hogging hdd in the background.

Any suggestions on what to do?

Been reviewing ALOT of client code and supplier’s lately. I just want to sit in the corner and cry.

Somewhere along the line the education system has failed a generation of software engineers.

I am an embedded c programmer, so I’m pretty low level but I have worked up and down and across the abstractions in the industry. The high level guys I think don’t make these same mistakes due to the stuff they learn in CS courses regarding OOD.. in reference how to properly architect software in a modular way.

I think it may be that too often the embedded software is written by EEs and not CEs, and due to their curriculum they lack good software architecture design.

Too often I will see huge functions with large blocks of copy pasted code with only difference being a variable name. All stuff that can be turned into tables and iterated thru so the function can be less than 20 lines long in the end which is like a 200% improvement when the function started out as 2000 lines because they decided to hard code everything and not let the code and processor do what it’s good at.

Arguments of performance are moot at this point, I’m well aware of constraints and this is not one of them that is affected.

The problem I have is the trying to take their code in and understand what’s its trying todo, and todo that you must scan up and down HUGE sections of the code, even 10k+ of line in one file because their design was not to even use multiple files!

Does their code function yes .. does it work? Yes.. the problem is readability, maintainability. Completely non existent.

I see it soo often I almost begin to second guess my self and think .. am I the crazy one here? No. And it’s not their fault, it’s the education system. They weren’t taught it so they think this is just what programmers do.. hugely mundane copy paste of words and change a little things here and there and done. NO actual software engineers architecture systems and write code in a way so they do it in the most laziest, way possible. Not how these folks do it.. it’s like all they know are if statements and switch statements and everything else is unneeded.. fuck structures and shit just hard code it all... explicitly write everything let’s not be smart about anything.

I know I’ve said it before but with covid and winning so much more buisness did to competition going under I never got around to doing my YouTube channel and web series of how I believe software should be taught across the board.. it’s more than just syntax it’s a way of thinking.. a specific way of architecting any software embedded or high level.

Anyway rant off had to get that off my chest, literally want to sit in the corner and cry this weekend at the horrible code I’m reviewing and it just constantly keeps happening. Over and over and over. The more people I bring on or acquire projects it’s like fuck me wtf is this shit!!! Take some pride in the code you write!

Team quarterly capacity planning:

- Confluence document created with a big table (+100 rows) by product / business. Each row is something that needs to be worked on for the coming quarter.

- Row 1 could be an Epic with 15 tickets attached. Row 2 could be adding a single log to our analytics. No consistency.

- For each row, we create a separate confluence document with the "technical details". 75% of the time these remain blank. 1% of the time there is something useful, the rest its a slightly longer version of the description from the bigger document.

- Each row gets a high level estimate by the leads. 50% of the time without sufficient background info to actually do get it accurate.

- These are then copied into the teams excel spreadsheet, where it will calculate if we are over/under capacity.

- We will go backwards and forwards between confluence and excel until we are "close enough" to under capacity without being too much.

- Once done, we then need to copy them into the org/division's excel spreadsheet. This document is huge, has every team on it and massive 50pt text saying "Do not put a filter on this document".

- Jira tickets + Epics will now be created for each one, with all the data be copied over by hand, bit by bit, by product. Often missing something.

- Last week, at the end of this process for Q2 (2 weeks late), 6 of the leads were asked to attend a 30 minute meeting to discuss how to group the line items together because we had too many for the bigger excel spreadsheet.

- This morning I was told business weren't happy with one of our decisions to delay one line item. Although they were all top priority (P0), one of them was actually higher than that again (P-1?) and we need to work it back in.

... so back to step 1

- Mid way through Q2, a new document will be created for Q3. Work items that didn't make the cut will be manually copied from one to the other. 50/50 whether anything that didn't get done on time in Q2 will make its way to the Q3 doc.

- "Tech excellence" / "Tech debt" items (unit/UI tests, documentation, logging, performance, stability etc) will never be copied over. Because product doesn't understand them and assumes therefore that they are unimportant.

==================

PS: I'd like to say this was a rare event for Q2, but no. Q4 and Q1 were so bad, we were made assurances from the director of engineering that he would fix this process for Q2. This is the new and improved process (I shit you not) that has resulted in nothing tangible.

"Sleep" is the last frontier in high performance computing. Is your code still slow? Just Sleep™, and you'll have your results instantly*.

* Speed benefits apply only to the sleeper. Sleep is not a solution for immediate deadlines.

I've optimised so many things in my time I can't remember most of them.

Most recently, something had to be the equivalent off `"literal" LIKE column` with a million rows to compare. It would take around a second average each literal to lookup for a service that needs to be high load and low latency. This isn't an easy case to optimise, many people would consider it impossible.

It took my a couple of hours to reverse engineer the data and implement a few hundred line implementation that would look it up in 1ms average with the worst possible case being very rare and not too distant from this.

In another case there was a lookup of arbitrary time spans that most people would not bother to cache because the input parameters are too short lived and variable to make a difference. I replaced the 50000+ line application acting as a middle man between the application and database with 500 lines of code that did the look up faster and was able to implement a reasonable caching strategy. This dropped resource consumption by a minimum of factor of ten at least. Misses were cheaper and it was able to cache most cases. It also involved modifying the client library in C to stop it unnecessarily wrapping primitives in objects to the high level language which was causing it to consume excessive amounts of memory when processing huge data streams.

Another system would download a huge data set for every point of sale constantly, then parse and apply it. It had to reflect changes quickly but would download the whole dataset each time containing hundreds of thousands of rows. I whipped up a system so that a single server (barring redundancy) would download it in a loop, parse it using C which was much faster than the traditional interpreted language, then use a custom data differential format, TCP data streaming protocol, binary serialisation and LZMA compression to pipe it down to points of sale. This protocol also used versioning for catchup and differential combination for additional reduction in size. It went from being 30 seconds to a few minutes behind to using able to keep up to with in a second of changes. It was also using so much bandwidth that it would reach the limit on ADSL connections then get throttled. I looked at the traffic stats after and it dropped from dozens of terabytes a month to around a gigabyte or so a month for several hundred machines. The drop in the graphs you'd think all the machines had been turned off as that's what it looked like. It could now happily run over GPRS or 56K.

I was working on a project with a lot of data and noticed these huge tables and horrible queries. The tables were all the results of queries. Someone wrote terrible SQL then to optimise it ran it in the background with all possible variable values then store the results of joins and aggregates into new tables. On top of those tables they wrote more SQL. I wrote some new queries and query generation that wiped out thousands of lines of code immediately and operated on the original tables taking things down from 30GB and rapidly climbing to a couple GB.

Another time a piece of mathematics had to generate all possible permutations and the existing solution was factorial. I worked out how to optimise it to run n*n which believe it or not made the world of difference. Went from hardly handling anything to handling anything thrown at it. It was nice trying to get people to "freeze the system now".

I build my own frontend systems (admittedly rushed) that do what angular/react/vue aim for but with higher (maximum) performance including an in memory data base to back the UI that had layered event driven indexes and could handle referential integrity (overlay on the database only revealing items with valid integrity) or reordering and reposition events very rapidly using a custom AVL tree. You could layer indexes over it (data inheritance) that could be partial and dynamic.

So many times have I optimised things on automatic just cleaning up code normally. Hundreds, thousands of optimisations. It's what makes my clock tick.

Fuck startups.

Back when I was an wee lad I interviewed for an startup, not knowing that startups are not real companies. The scumbag interviewer, who was also the owner of the outfit, asked me what I was looking in a company. I said "fair wages, a non-antagonic environment and projects with real roadmaps".
He asked me to elaborate. I said, "You know, if today your product is a sales platform, I do not want to come into work next week and discover it is now an air travel tickets marketplace, or come back the very next day and discover it is now an automated pizza factory, or in the next day and it is now a crypto exchange..."

The scumbag looked PISSED. "Sorry, but we are looking for someone who likes the challenges of a dynamic environment (read: we do not have a business model and we hate the very idea of trying to make money out of our company), and you do not fit the profile"

Startups are not real companies, i.e. they do not systematically charge money in exchange for goods or services in amounts that exceed the cost of providing said goods or services. Most startups are just tax fronts for money laundering schemes. The rest are just playthings for rich assholes who can't get a real output-producing job. Those two categories are not mutually exclusive.

Take Facebook, for example. The poster child of startups. The Zucker that owns it just announced they are setting impossible performance targets on purpose, not even attempting to hide the fact that it is just a way to lay off large quantities of employees without using the words "massive lay offs". Companies, real thin-margin, lots-of-regulation profit-driven companies do not do that. They are not some sort of "capitalist woke", real CEOs just know that if their companies largely miss performance targets on their tenure, purposely or not, next it will be their neck on the chopping block. Because they can be fired if the KPI charts say they suck. But the Zucker cannot be fired, not even after commanding their beanbag and tap beer offices to be heated exclusively by burning hundred dollar bills.
So the Zucker is not interested in performance. Not even in lay offs as expense cutting measures - investors are an infinite source of free money for startups. The Zucker just wants to project power, especially now that engineers are not so confident in the stability of they high-paying jobs.

So are irrelevant 500-souls-or-less self-aggrandizing startups. Their owners are there because it is in vogue to have a startup or ten. And will have that startup pivot to whatever sounds fancy that season. After all, only poor people care about things like EBITDA and profit margins repeatability - A.K.A. "getting more money".

Fuck startups.

Oh dear, a scaling problem I solved was replacing some Regex matching with simpler string functions. While I'm a huge fan of Regex, it's unreal how much performance they can suck out of some high-n loops...
I got about 120x out of some critical code thus making a CPU upgrade unnecessary.

So, I found this :

Dear Tech Support:
Last year I upgraded from Girlfriend 7.0 to Wife 1.0. I soon noticed that the new program began unexpected child processing that took up a lot of space and resources. In addition, Wife 1.0 installed itself into all other programs and now monitors all other system activity. Applications such as Poker Night 10.3, Football 5.0, HuntingAndFishing 7.5, and Racing 3.6. I can't seem to keep Wife 1.0 in the background while attempting to run my favorite applications. I'm thinking about going back to Girlfriend 7.0, but the uninstall doesn't work on Wife 1.0. Please help!

Dear Troubled User:
This is a very common problem. Many people upgrade from Girlfriend 7.0 to Wife 1.0, thinking that it is just a Utilities and Entertainment program. Wife 1.0 is an OPERATING SYSTEM and is designed by its Creator to run EVERYTHING!!! It is also impossible to delete Wife 1.0 and to return to Girlfriend 7.0. It is impossible to uninstall, or purge the program files from the system once installed. You cannot go back to Girlfriend 7.0 because Wife 1.0 is designed not to allow this. Look in your Wife 1.0 manual under Warnings-Alimony-Child Support. I recommend that you keep Wife 1.0 installed and work on improving the configuration. I suggest installing the background application YesDear 99.0 to alleviate software augmentation.

The best course of action is to enter the command C:\APOLOGIZE because ultimately you will have to do this before the system will return to normal anyway.

Wife 1.0 is a great program, but it tends to be very high maintenance. Wife 1.0 comes with several support programs, such as CleanAndSweep 3.0, CookIt 1.5 and DoBills 4.2. However, be very careful how you use these programs. Improper use will cause the system to launch the program NagNag 9.5. Once this happens, the only way to improve the performance of Wife 1.0 is to purchase additional software. I recommend Flowers 2.1 and Diamonds 5.0, but beware because sometimes these applications can be expensive.

WARNING!!! DO NOT, under any circumstances, install SecretaryWithShortSkirt 3.3. This application is not supported by Wife 1.0 and will cause irreversible damage to the operating system. 

WARNING!!! Attempting to install NewGirlFriend 8.8 along with Wife 1.0 will crash the system.

(see Wife 1.0 manual, Apologize, High Maintenance & Secretary with Short Skirt)

Bethesda is full of shit. Starfield somehow needs a super new PC because it alledgedly uses modern SW tech.

Strange point: while a high-end PC with 7800X3D and 4090 makes the performance bearable (though not great), the graphics don't look spectacular. In fact, they look outdated.

No Bethesda, you don't use modern tech. You require modern HW tech to make up somewhat for your shitty engine and incompetent devs.

life as devs in tough companies, high expectation and shit.

I've never used Windows in my day-to-day life. No kidding.
When I got my father's first computer, I used an old distribution called BBC Linux. I didn't have any computer knowledge, it was my first contact with a computer, so I went to a friend's house and asked for a CD to install on my computer. I don't know if this friend ended up making a "gotcha" and thought I'd give up, but I just read the manuals and fell in love. That was year 2000.
Then I used Conectiva Linux, then I went to Red Hat 9, then Slackware, then in 2007 I started using Solaris. And I stayed on Solaris (Solaris 10, Solaris Nevada and OpenSolaris) until 2011.
In 2011 I bought a Mac. I stayed at Apple until 2020, when I couldn't stand Apple forcing me to buy new computers (I still don't understand how a 2011 iMac, i5 (4 Hyper Thread cores) with 16GB of RAM, 1TB SSD only runs up to High Sierra).
Then I bought a Dell. It came with Windows 10, the first thing I did was install WSL2. I could not stand it, the system is bad, sorry. I installed OpenSuse and have been using it for two years.

It's just that every day someone tells me "how can you use this"? "There is no alternative to Windows, do you want to be different?"

I know that my story was the reverse of the "mainstream", so I'm going to talk about my vision of Windows, that in my brain it is actually the "alternative".

- Having a file explorer without "tabs" in 2022 is unthinkable for me.
- I love terminal. And the Windows terminal is very limited. "ps ... | awk ... | xargs ..." is a must for me. "find ./ -name '...' -exec ..."... these things on Windows are totally "different" and have the "powershell way" while all other operating systems keep the same form. And cygwin is not an option. As Wine for serious work is also not.
- Dragging a file into the terminal, and having it write its path, is so natural, that when Windows didn't do it, I was dismayed.
- I've always used StarOffice, OpenOffice and now LibreOffice. All the people in my story received my documents and reports as a PDF and no one complained. Until a coworker saw me editing in LibreOffice and said "oh I want it in word format". As long as he didn't know, everything was fine, right?
- Windows is paid. And is there advertising? I don't understand. And I refuse. If you want to display advertising, then excuse me. I have no problem paying, I'm not an opensource shiite. It's just that paying and not working bothers me much more than an opensource that I can fix or expect a fix knowing the good will of the people involved.
- Hyper-V is a joke. QEMU/KVM is better, and Bhyve on FreeBSD which is a very young project, is already a million times better than Hyper-V.
- Developing in C/C++ for Windows is only possible in two ways: Either you've always lived in Windows and your brain is conditioned, or you compile with MSYS2 (CLang or GCC).
- There is no significant evolution of the windows desktop since 95.
- Multiple workspace support with multiple monitors, not ready. It's another joke.
- REGEDIT does not need any comment.
- The system loses performance over time. I still don't know how Windows achieves this.
- I've seen people complain about desktop fragmentation on Unix and Linux. Many DEs end up leaving applications with different themes (like running a Qt application in Gnome and GTK in KDE), but to be quite honest, the lack of Windows standard bothered me much more. Even Microsoft's own software is completely different: Control Panel, Calculator, Paint and Office, To-Do, and Settings, have horrible style differences and look-and-feel fragmentation.
- Dark mode has not been implemented. It's another joke. Many applications are white while everything else is dark. Sorry, even on Linux which is a mess, this has been resolved. And well resolved.
- NTFS? Serious?
- C:, D:.. It doesn't convince me since DOS.
- Bloatware.
- News "biased" in the search bar is a lack of respect for those who use the computer to work.

And that. For me, Windows is the alternative operating system. I can't take Windows seriously, for me it's an experimental one like Haiku or ReactOS. It's good to play.

About market share, it doesn't convince me to use it. But convinces me to sell. I've always developed applications to run on Windows. And when I need it, I turn on a VM to compile the project. But in everyday life? Impractical.

I can't get the wifi generation. I love cables (except when they are in front of the tv), their performance, their plug-n-play without conflicts, that high level of nerdy childish porn of 80's in all the magnificence. It's just me? *snowflake feelings*

There was a sales manager who was raked with overseeing me and another dev finish a last minute request project. He said at one point to the other dev that he was mad at developers because we understood something that he would never understand.

This same manager would often sit in on estimation meetings and constantly say that we were estimating too high and needed to come up with faster solutions. When we would offer him with caveats of possible technical debt or unintended side-effects/performance issues, he'd want us to go with that solution. He would then complain that we were always wanting to work on technical debt and that our application was slow. He would also ask for very high level estimates for large, unscoped features/apps without any meaningful level of detail, then hold us to the high-level estimated date even after revealing additional features previously unmentioned.

We learned to never compromise on the right solution and to push back hard on dates without proper scoping. They didn't learn, so I and most of the good devs left.

a client today wanted a specialized high performance, extremely stable, stock management software for pharmaceutical products, he also wants the software distributed, cross platform, and expect the delivery to be in a week or so, oh and did i mention that he also wants it to have an extremely good looking ui,
he got offended that i said you can only have one or two of those things not all of them,
for context, I'm just a freelancer not a big company and doing what he wants is impossible for me, also it was a billion ages since i worked on anything desktop related, web is all I'm diving into lately

Somehow my brain assumes that code is high performance code when its all written in lowercase... :D

Me working in High Performance Computing :
CPU/GPU in full throttle ... go brrrr...

Me working on an app:
Should put sleep() in the while loop so as not to overwork the CPU

😑😑

This will definitely trigger many but the truth regardless of how you feel is the greatest programmers are those who understand both the hardware level and software .. only then are you more than a dev or programmer.. you are an engineer...

I challenge the devs who dis believe to go out and learn to build circuits, write optimized, efficient bare metal code.: no sdk.. no api... no drivers ..remove the unneeded abstraction layers that have blinded you...build it yourself, expand your potential and understanding..

Not only will you become more valuable overall, but you will write better code as you are more conscious of performance and space and physics of the physical layer.

I’m not talking about Arduino or raspie

Those who stand strong that high level abstraction languages and use of third party apis is a sufficient sustainable platform of development are blind to reality.. the more people who only know those levels, the less people pushing the industry of the low level.., which is the foundation of everything in the industry.. without that low level software the high level abstractions and systems cannot run

Why did we have huge technology advancements from 70s to early 2000s.... because more people in our industry understood the hardware layer..: wrote the software at the less abstracted layers..

Yeah it takes longer todo things at that low level abstraction.. but good robust products that change the world and industry don’t take a few week or months to build.....

Take this with what you will... I’m just trying to open the eyes of the blind developers to the true nature and reality of our industry

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...

It's 2:49AM

my fucking brain starts working in high performance mode right now and sleeps not exist anymore :/

Is your code green?

I've been thinking a lot about this for the past year. There was recently an article on this on slashdot.

I like optimising things to a reasonable degree and avoid bloat. What are some signs of code that isn't green?

* Use of technology that says its fast without real expert review and measurement. Lots of tech out their claims to be fast but actually isn't or is doing so by saturation resources while being inefficient.
* It uses caching. Many might find that counter intuitive. In technology it is surprisingly common to see people scale or cache rather than directly fixing the thing that's watt expensive which is compounded when the cache has weak coverage.
* It uses scaling. Originally scaling was a last resort. The reason is simple, it introduces excessive complexity. Today it's common to see people scale things rather than make them efficient. You end up needing ten instances when a bit of skill could bring you down to one which could scale as well but likely wont need to.
* It uses a non-trivial framework. Frameworks are rarely fast. Most will fall in the range of ten to a thousand times slower in terms of CPU usage. Memory bloat may also force the need for more instances. Frameworks written on already slow high level languages may be especially bad.
* Lacks optimisations for obvious bottlenecks.
* It runs slowly.
* It lacks even basic resource usage measurement.

Unfortunately smells are not enough on their own but are a start. Real measurement and expert review is always the only way to get an idea of if your code is reasonably green.

I find it not uncommon to see things require tens to hundreds to thousands of resources than needed if not more.

In terms of cycles that can be the difference between needing a single core and a thousand cores.

This is common in the industry but it's not because people didn't write everything in assembly. It's usually leaning toward the extreme opposite.

Optimisations are often easy and don't require writing code in binary. In fact the resulting code is often simpler. Excess complexity and inefficient code tend to go hand in hand. Sometimes a code cleaning service is all you need to enhance your green.

I once rewrote a data parsing library that had to parse a hundred MB and was a performance hotspot into C from an interpreted language. I measured it and the results were good. It had been optimised as much as possible in the interpreted version but way still 50 times faster minimum in C.

I recently stumbled upon someone's attempt to do the same and I was able to optimise the interpreted version in five minutes to be twice as fast as the C++ version.

I see opportunity to optimise everywhere in software. A billion KG CO2 could be saved easy if a few green code shops popped up. It's also often a net win. Faster software, lower costs, lower management burden... I'm thinking of starting a consultancy.

The problem is after witnessing the likes of Greta Thunberg then if that's what the next generation has in store then as far as I'm concerned the world can fucking burn and her generation along with it.

A better, lightweight cloud through golang's high performance and low footprint

I'm struggling at work. I hate senior mgmt at this company so much it's actually affecting my ability to produce work.

Fuckers high up have been delaying performance reviews for like a year, but they get their fucking bonuses with no delay. I can't afford not to have a job, so I'm trying to work, but it's hard. I try to keep things in perspective that they're still paying me so I should just do my job.. but how do you do it if you hate those cunts at the top so much. I became so toxic because of all the resentment too.

I just realized one of today's emails is asking to review again that spaghetti program and this time figure out how to optimize performance because it is getting flagged for high cpu and database usage. A Niagra of If-statements and nobody-cares-for-comments-and-technical-documentation.

*bleep* *bleep* *bleep* previous programmer.

I'll deal with this torture on Monday.

I've been a Macbook user for over a decade, after the initial disappointment of the 2016 MacBook Pro release I decided to move to a PC, against my better judgement I decided to buy a new Dell XPS 15, after reading all the reviews praising it's build quality and performance + it seems to have good hardware for Linux compatibility.
Soo much regret, I couldn't be more disappointed, it's such a piece of shit, I admit I probably got a bad egg, but dealing with Dell support is like pulling hairs from my testicle sack. If I have to pay an extra $500-$1000 on my next laptop for an "Apple Tax" to get a product that has been through proper quality control and has awsome customer service so be it, last time I try something new.
BTW I'm not a PC hater, I just wish more companies made high quality products.

python machine learning tutorials:
- import preprocessed dataset in perfect format specially crafted to match the model instead of reading from file like an actual real life would work
- use images data for recurrent neural network and see no problem
- use Conv1D for 2d input data like images
- use two letter variable names that only tutorial creator knows what they mean.
- do 10 data transformation in 1 line with no explanation of what is going on
- just enter these magic words
- okey guys thanks for watching make sure to hit that subscribe button

ehh, the machine learning ecosystem is burning pile of shit let me give you some examples:

- thanks to years of object oriented programming research and most wonderful abstractions we have "loss.backward()" which have no apparent connection to model but it affects the model, good to know
- cannot install the python packages because python must be >= 3.9 and at the same time < 3.9
- runtime error with bullshit cryptic message
- python having no data types but pytorch forces you to specify float32
- lets throw away the module name of a function with these simple tricks:
"import torch.nn.functional as F"
"import torch_geometric.transforms as T"
- tensor.detach().cpu().numpy() ???
- class NeuralNetwork(torch.nn.Module):
def __init__(self):
super(NeuralNetwork, self).__init__() ????
- lets call a function that switches on the tracking of math operations on tensors "model.train()" instead of something more indicative of the function actual effect like "model.set_mode_to_train()"
- what the fuck is ".iloc" ?
- solving environment -/- brings back memories when you could make a breakfast while the computer was turning on
- hey lets choose the slowest, most sloppy and inconsistent language ever created for high performance computing task called "data sCieNcE". but.. but. you can use numpy! I DONT GIVE A SHIT about numpy why don't you motherfuckers create a language that is inherently performant instead of calling some convoluted c++ library that requires 10s of dependencies? Why don't you create a package management system that works without me having to try random bullshit for 3 hours???
- lets set as industry standard a jupyter notebook which is not git compatible and have either 2 second latency of tab completion, no tab completion, no documentation on hover or useless documentation on hover, no way to easily redo the changes, no autosave, no error highlighting and possibility to use variable defined in a cell below in the cell above it
- lets use inconsistent variable names like "read_csv" and "isfile"
- lets pass a boolean variable as a string "true"
- lets contribute to tech enabled authoritarianism and create a face recognition and object detection models that china uses to destroy uyghur minority
- lets create a license plate computer vision system that will help government surveillance everyone, guys what a great idea

I don't want to deal with this bullshit language, bullshit ecosystem and bullshit unethical tech anymore.

We use at our company one of the largest Python ORM and dont code ourselfs on it, event tough I can code. Its some special contract which our General Manager made, before we as Devs where in the Project and everything is provided from the external Company as Service. The Servers are in our own Datacenter, but we dont have access.

We have our Consultants (Project Manager) as payd hires and they got their own Devs.

Im in lead of Code Reviews and Interfaces. Also Im in the "Run" Team, which observes, debuggs and keeps the System alive as 3rd-Level (Application Managers).

What Im trying to achieve is going away from legacy .csv/sftp connections to RestAPI and on large Datasets GraphQL. Before I was on the Project, they build really crappy Interfaces.

Before I joined the Project in my Company, I was a Dev for a couple of Finance Applications and Webservices, where I also did coding on Business critical Applications with high demand Scaling.

So forth, I was moved by my Boss over to the Project because it wasn't doing so well and they needed our own Devs on it.

Alot of Issues/Mistakes I identified in the Software:
- Lots of Code Bugs
- Missing Process Logic
- No Lifecycle
- Very fast growing Database
- A lot of Bad Practices

Since my switch I fixed alot of bugs, was the man of the hour for fixing major Incidents and so on so forth. A lot of improvements have been made. Also the Team Spirit of 15+ People inside the Project became better, because they could consult me for solutions/problems.

But damn I hate our Consultants. We pay them and I need to sketch the concepts, they are to dumb for it. They dont understand Rest or APIs in general, I need to teach them alot about Best Practices and how to Code an API. Then they question everything and bring out a crooked flawed prototype back to me.

WE F* PAY THEM FOR BULLCRAP! THEY DONT EVEN WRITE DOCUMENTATION, THEY ARE SO LAZY!

I even had a Meeting with the main Consultant about Performance Problems and how we should approach it from a technical side and Process side. The Software is Core Business relevant and its running over 3 Years. He just argumented around the Problem and didnt provide solutions.

I confronted our General Manager a couple of times with this, but since 3 Years its going on and on.

Im happy with my Team and Boss, they have my back and I love my Job, but dealing with these Nutjobs of Consultants is draining my nerves/energy.

Im really am at my wits end how to deal with this anymore? Been pulling trough since 1 year. I wanna stay at my company because everything else besides the Nutjob Consultants is great.

I told my Boss about it a couple of times and she agrees with me, but the General Manager doesnt let go of these Consultants.

Even when they fuck up hard and crash production, they fucking Bill us... It's their fault :(

Alright, I'll try writing about my recent experience without getting too emotional.

A few months ago, I started a tech job in London and immigrated here for that job. I was glad this company wanted to sponsor a visa, as that was a requirement for me to live here.

Unfortunately, after only a few months in, I learned that the company I joined wasn't quite as nice as I thought it would be. Bullying seemed to be part of the culture. On occasion, I saw coworkers crying. One of my close coworkers was dangerously close to burnout and then "left with mutual agreement". The environment felt like a high school cafeteria. People were drinking heavily early in the afternoon and people were leaving almost at the speed of a revolving door.

I recognized very early on that this was not a healthy environment for me, but as I just signed a rental agreement for a year, and spent a large amount to move here, I was kind of trapped.

Very early on, I was told that the two people before me in the same role were let go right before their probation ended. That scared me off, for reaching out to management or HR. I didn't have the financial needs to lose my job, and due to visa restrictions, therefore would have to leave the country.

When my probation was about to end, and I learned that my performance was good, I decided to provide feedback to my manager. I only mentioned a few things, but still enough. The manager seemed receptive, but it did not seem like he was actually willing to approach the problem itself.

Sometime later, I spoke to HR, explaining some of the issues, and explained my intent to resign. The rep pretended to care, but it did not seem sincere. At the same time, I reached an agreement with my landlord, so I believed I had enough money to safely move out of the country.

A few days after I resigned, the HR rep told me that I owed the company a large amount of money. A part of it was in the contract, which I accounted for. Another part, she was claiming, but was not properly defined in the contract. It said something, but it was confusing. I got a checked later with a legal advisor, and from what I understood, the company would never be able to make me pay that extra amount. This simply because of the contract being so vague.

I told the rep multiple times in the initial meeting about the flaws in the contract, but she ignored everything I said. I then made a counteroffer trying to get her to back off. She then put that in writing, but manipulated my words and kept out all the arguments I made about contract flaws, and my departure being the company's fault.

I didn't receive a reply to my counteroffer for days. It was stressing me out as this could mean I would run out of money soon. Only a few days passed before I got a medical emergency at work just because of the stress all of this caused me.

I saw a doctor and immediately got 2 weeks of sick leave. When I contacted the company again, I was able to terminate my contract, without returning to the office. However, they still didn't want to waive the extra amount of money.

The HR rep pointed out in written communication to my lawyer, something in the trend of "if something wasn't clear in the contract, he should've just asked for details". In that same correspondence, it also stated that they were offering 'as a favor to me' to reduce the extra amount to only a third of it.

Since I never actually wanted to go to court anyway, I decided to settle with that. Now I'm packing to move out of the country, without a job and soon to be completely broke. If I would've stayed where I were and never moved to London, and never worked a day for the past 7 months, I would've had more money on my savings account than I have at this point in time.

I hope I at least learned something from this. I don't think I will move somewhere with a company-sponsored visa again anywhere soon...

Thanks for listening. Ranting does make you feel better :)

So I was rejected by the management today for promotion to Senior 2 although I have done several major feature developments + infra design and basically end to end ownership.

Reason for no promotion? That's the best fucking part, according to the feedback, the work I performed on the service I created is well-designed,
and the code quality is commendable. However, they pointed out a notable difference in code quality between the micro-service
I built and the rest of the project developed by others. This, apparently, suggests that I lack a strong sense of ownership over the broader product.

First of all, we have super tight deadlines (almost 996), and I burned midnight oil to make sure the service I am in-charge of is designed really well.
Also, how in the flying fuck the other how the inability of others to maintain good code quality elsewhere in the product is being used as evidence against my sense of ownership
and initiative in ensuring high engineering quality for the repository I wasn't even working on

What a delusional management, the entire feedback feels like just an excuse to fuck off, we are not promoting you...
May be instead of doing actual engineering work, I should have just do minimal work and write more design docs / technical artifacts

It is very demoralizing after I worked hard for so many months, product went out really well.. yet when performance review comes, rejected with a petty reason

It is approximately 42 degrees C outside. And guess whose fucking compressor just went to shit? Mine. Fucking piece of shit. I absolutely fucking hate this shit. Finding the time to go to the shop is pointless when I can fix it myself, but IN the fucking event that the compressor is actually faulty and needs to be replaced then I would have to struggle to wait for the fucking part to get here. If my luck permits and this is an issue that is fixable through a simple relay change then fucking hooray.

But I know how fucking shitty my fucking luck is and its going to fuck me in the ass probably. I will troop through the heat, no problem, but I am the one that carries my 2 year old daughter everywhere and I am not about to put her through that bullshit.

So I call my wife and explain to her the situation, I don't need for her to do fucking anything, I can take care of it myself, but I tell her NOT to have me go out on random bullshit with the girl while the car is like that, I did it to make her understand beforehand because every day is an additional 1 and a half hours of driving around the city to take her do bullshit. I told her that in the event of me needing to go pick something up then it would have to be after the fucking sun goes out(which in this fucking bullshit ass town it happens after fucking 7 or 7:30pm) and she would have to stay home with the girl. What does she do? she gets upset. Of course she got fucking upset. Like if I need that fucking bs right now. OH and my fucking main Linux machine is apparently having battery issues.

OAN my manager gave me my performance review yesterday. The she made are outstanding and my score is perfect. The board is going to give a raise to everyone of us that got an high enough score so that got me in a good mood. I am holding on to that feeling before I lose my shit. Every single fucking time some bs puts me in this mood I am constantly wishing that a motherfucker would.

Fucking bullshit man. Can't have a FUCKING break anyfuckingwere.

This just in on an episode of Murphy's fucking law.

Question;
I have heard about Apache Hadoop for a while but never bothered to learn anything about it.
What can it be used for? Can I use it for hosting thousands of websites powered by php/hhvm?
I am starting to have a need for a really HA and High Performance solution that is futureproof too. My current solution is doing great also when it comes to performance and HA, but it is always nice to try out new things...

So the question is, can Hadoop be used in a hostingsolution?

Had a manager that, during performance reviews, would say things like:
"You need to work harder on managing our clients' warm fuzzies."
"I can't give you a hard number to strive for on this metric here because you'll just do the minimum"

Needless to say, the turnover in that group was insanely high.

So, I produce a monthly report for our customer service department each month, and this report includes various statistics related to our company's support performance. Two of the included statistics are the "Average Speed of Answer" (ASA for short) and the "Abandoned Call percentage" (ABD % for short) that are derived from client calls to support.

The formulae for these values are:
- ASA = time in seconds all calls that were answered spent waiting to be answered divided by the number of answered calls - displayed as hh:mm:ss

- ABD % = number of abandoned calls minus those that were abandoned in under 10 seconds (referred to as "short abandoned") divided by the sum of total calls that were offered minus the sum of short abandons & transfers

These statistics are also included in a daily version of the same report that all Customer Service leadership personnel have access to.

Now, every single fucking month the same Sr. Manager always has some kind of "discrepancy" with the monthly report that ALWAYS boils down to his dumbass trying to average shit on the daily Excel reports for that month and it being different than what the monthly report is showing. Now, these reports ONLY display the calculated value for any calculated fields mind you - not the raw values of the DB fields used in said calculations.

This month I have to tell this shit-for-brains that you can't just take an average of ASA & ABD % from the Daily's and compare them to the Monthly numbers because their calculated fucking fields!!!

Come to think of it, this has been his issue for like the past 5 months, and I seriously can't fix stupid!

Sometimes I just wanna reply to his snarky ass, corporate bullshit emails like, "BRUH!, The only motherfucking discrepancy I can locate is your IQ and your fucking title - that shit don't correlate homie! Need to take that ass back to High School statistics or something!"

But I digress...

TL;DR
I have to deal with a Sr. Manager who doesn't fucking realize you can't average a calculated field from a daily report and think it's gonna match up with the monthly report. I believe he is borderline retarded, and I often wonder how he got the "Sr." In his title let alone "Manager".

Oh wait, this is corporate America - you just gotta kiss the most ass... never mind.

The next step for improving large language models (if not diffusion) is hot-encoding.

The idea is pretty straightforward:
Generate many prompts, or take many prompts as a training and validation set. Do partial inference, and find the intersection of best overall performance with least computation.

Then save the state of the network during partial inference, and use that for all subsequent inferences. Sort of like LoRa, but for inference, instead of fine-tuning.

Inference, after-all, is what matters. And there has to be some subset of prompt-based initializations of a network, that perform, regardless of the prompt, (generally) as well as a full inference step.

Likewise with diffusion, there likely exists some priors (based on the training data) that speed up reconstruction or lower the network loss, allowing us to substitute a 'snapshot' that has the correct distribution, without necessarily performing a full generation.

Another idea I had was 'semantic centering' instead of regional image labelling. The idea is to find some patch of an object within an image, and ask, for all such patches that belong to an object, what best describes the object? if it were a dog, what patch of the image is "most dog-like" etc. I could see it as being much closer to how the human brain quickly identifies objects by short-cuts. The size of such patches could be adjusted to minimize the cross-entropy of classification relative to the tested size of each patch (pixel-sized patches for example might lead to too high a training loss). Of course it might allow us to do a scattershot 'at a glance' type lookup of potential image contents, even if you get multiple categories for a single pixel, it greatly narrows the total span of categories you need to do subsequent searches for.

In other news I'm starting a new ML blackbook for various ideas. Old one is mostly outdated now, and I think I scanned it (and since buried it somewhere amongst my ten thousand other files like a digital hoarder) and lost it.

I have some other 'low-hanging fruit' type ideas for improving existing and emerging models but I'll save those for another time.

High performance Java.

Tryna decide what I want my next job to be, I currently span some performance stuff, some data stuff. I'm torn between going hardcore c++ high performance compute or pure data science.

Why on Earth would a Performance Testing application such as JMeter have such a low Java heap space by default.. i mean wouldnt it make sence to set this as high as possible for a Performance Testing tool ? 😞

More high-level stuff, sweet libs, awesome frameworks and the next generation of devs complaining about bad performance and too much abstraction.

Coming from NodeJS, writing APIs with Express, I now do my first steps writing APIs in golang with gin.

Now I know, Express is not the fastest solution out there, but I mean - a good 30ms is alright for non-high-performance backends. And I always thought that's on the faster end of HTTP handling..

..but then I used gin. A GET request doing a MongoDB-write and returning some json. 3ms response time. THREE MILISECONDS. holy fuck. By it's debug logs the actual handling took 540 MICROSECONDS. holy fuck I'm in love.

Here is a weird fact I have been thinking about this evening:

Helio X20 was the only mainstream ARM processor that had 10 CPU cores. It was first introduced in 2015, however no more ARM processors with high core count were used since then..

Nowadays smartphone processors have `8` cores max 🤔🧐

I guess 8 cores the reasonable limit for smartphones. Must have something to do with cost-to-performance factor

!rant/story:

Aaayoo issya boi the OG rapper straight outta Compton, wassup?!

Nah, for real, though.: How are y'all doing? It has been a long time. I hope y'all are having a great time (can sense some peoples' incoming negative comments due to corona).

I built my completely new first gaming rig like a few weeks ago after my school laptop stopped showing any signals.

The specifications are the following.:
- Mobo: MSI B450 TOMAHAWK MAX
- CPU: AMD Ryzen 5 3600 (no iGPU)
- dGPU: KFA2 RTX 2070 SUPER OC
- 2nd dGPU: GTX 550 TI (this one gets a new rant/post)
- RAM: 2x G.SKILL Ripjaws V 8 GB 3600 MHz
- PSU: Be quiet 650 W (It was the platinum edition afaik. I originally bought the 600 Watt Gold edition, but somehow they sent me the 650 Watt for no additional charge... which is great for me haha)
- HDD: 2x 4TB NAS HDD in RAID1 configuration (to load all of my games around 2 TB right now. Got the two HDDs for 110 Euro including the SATA Data cables)
- SSD: One Intenso 240 GB SSD and a reused Samsung 256 GB SSD from my old broken Lenovo laptop
- Case: Be quiet Pure Base 500 black with a glass panel on the side

While building my first PC, it was one hell of a challenge. I knew how it all was working in theory, but to put it all together, practically, was a bit of a challenge, but it was a nice challenge. I learned a lot and have a performance gain I could only ever dream of.

I used to play my games first on a Toshiba satellite l750d laptop (around 40 fps in cs:go with the lowest gfx settings) and then on a Lenovo e51-80 laptop (around 30 fps max minecraft with no shaders and texture packs).

Now I play cs:go on Kubuntu with 400 fps at peak with ultra high graphics. It is unbelievable.

I couldn't trust the system when I turned on the fps display the first time I saw it.

Low performance because of shitty attention span and high procrastination
Don't get higher salary because low performance
With low salary I can't go to a professional to get a medication prescription and couldn't afford medication anyway

I just wanted to have a life and live it, be able to afford to go on dates or just do things, afford a car so I can go anywhere, I had this little online romance where I couldn't afford to go see the girl, she ended up just ghosting me and it fucking destroyed me

To get this low-paying job, I was forced to open a company to work as a contractor in order to circumvent labor laws (common practice in my country, encouraged by shitty labor laws and unstable local currency); I end up having to pay to get paid

To top it all, the government just wants more and more taxes and my pay is worth less and less

My mom wasted all her money and now needs my help

I should just find a way to kill myself

A very long rant.. but I'm looking to share some experiences, maybe a different perspective.. huge changes at the company.

So my company is starting our microservices journey (we have a 359 retail websites at this moment)

First question was: What to build first?

The first thing we had to do was to decide what we wanted to build as our first microservice. We went looking for a microservice that can be used read only, consumers could easily implement without overhauling production software and is isolated from other processes.

We’ve ended up with building a catalog service as our first microservice. That catalog service provides consumers of the microservice information of our catalog and its most essential information about items in the catalog.

By starting with building the catalog service the team could focus on building the microservice without any time pressure. The initial functionalities of the catalog service were being created to replace existing functionality which were working fine.

Because we choose such an isolated functionality we were able to introduce the new catalog service into production step by step. Instead of replacing the search functionality of the webshops using a big-bang approach, we choose A/B split testing to measure our changes and gradually increase the load of the microservice.

Next step: Choosing a datastore

The search engine that was in production when we started this project was making user of Solr. Due to the use of Lucene it was performing very well as a search engine, but from engineering perspective it lacked some functionalities. It came short if you wanted to run it in a cluster environment, configuring it was hard and not user friendly and last but not least, development of Solr seemed to be grinded to a halt.

Elasticsearch started entering the scene as a competitor for Solr and brought interesting features. Still using Lucene, which we were happy with, it was build with clustering in mind and being provided out of the box. Managing Elasticsearch was easy since there are REST APIs for configuration and as a fallback there are YAML configurations available.

We decided to use Elasticsearch since it provides us the strengths and capabilities of Lucene with the added joy of easy configuration, clustering and a lively community driving the project.

Even bigger challenge? Which programming language will we use

The team responsible for developing this first microservice consists out of a group web developers. So when looking for a programming language for the microservice, we went searching for a language close to their hearts and expertise. At that time a typical web developer at least had knowledge of PHP and Javascript.

What we’ve noticed during researching various languages is that almost all actions done by the catalog service will boil down to the following paradigm:

- Execute a HTTP call to fetch some JSON

- Transform JSON to a desired output

- Respond with the transformed JSON

Actions that easily can be done in a parallel and asynchronous manner and mainly consists out of transforming JSON from the source to a desired output. The programming language used for the catalog service should hold strong qualifications for those kind of actions.

Another thing to notice is that some functionalities that will be built using the catalog service will result into a high level of concurrent requests. For example the type-ahead functionality will trigger several requests to the catalog service per usage of a user.

To us, PHP and .NET at that time weren’t sufficient enough to us for building the catalog service based on the requirements we’ve set. Eventually we’ve decided to use Node.js which is better suited for the things we are looking for as described earlier. Node.js provides a non-blocking I/O model and being event driven helps us developing a high performance microservice.

The leap to start programming Node.js is relatively small since it basically is Javascript. A language that is familiar for the developers around that time. While Node.js is displaying some new concepts it is relatively easy for a developer to start using it.

The beauty of microservices and the isolation it provides, is that you can choose the best tool for that particular microservice. Not all microservices will be developed using Node.js and Elasticsearch. All kinds of combinations might arise and this is what makes the microservices architecture so flexible.

Even when Node.js or Elasticsearch turns out to be a bad choice for the catalog service it is relatively easy to switch that choice for magic ‘X’ or component ‘Z’. By focussing on creating a solid API the components that are driving that API don’t matter that much. It should do what you ask of it and when it is lacking you just replace it.

Many more headaches to come later this year ;)

Initialize a collection, store values in it and then filter values out of it and none of your code may be inefficient, such as having O(n)² performance. Your code must also pass the predefined Test Suite. You have 15 minutes.

This sounds simple but it's not.

This was for a Google-type company that has high standards.

What’s your favorite high performance video card for PC gaming for between $250-$300?

These fucking deepshet, spoiled retards
they expert me to build software not from the ground but from the fucking foundation up to release date all by myself
they also expert me to do all required research
also expert me to do the fucking marketing
they expert me to bring new fucking business
They expert me to work at High performance
They expert me to do stock inventory as well

They fucking sit me in shity meetings
WHAT THA FUCK IS THIS SHIT

When you hear “Haskell performance”, what comes to your mind? I was never really interested in Haskell since I had Clojure, and I thought Haskell might be slow.

Haskell with GHC is actually as fast as C or even faster. Haskell runs right on your hardware, no VM or interpreter.

When a program is small, the performance is comparable to C. Sometimes it’s quicker, sometimes not. But when a program is large, Haskell implementation would be faster if you’re not a robot that generates perfect C code.

It’s both very high-order AND very fast. You don’t need math to code in Haskell.

Too bad there are no kewl libraries.

When you have high performance set, yet your lame CPU won't get above 0.75Ghz, so you have to constantly reboot to hit the 3.50Ghz jackpot

My department just installed a new high performance GPU, so :
1. Good bye, my old laptop GPU!
2. Let's play around and break the shiny thing! 😎

(more likely I will be the one who break down due to frustration though 😬)

I wrote a tiny Windows app that switches to High Performance energy profile when plugged into AC and switches to Balanced when on battery. It sits on the tray and you can override settings manually. I made it back when I used Windows 10, but it's also handy on other Windows versions

Is it worth publishing?

They dont mention it in any reviews but dell has cooling problems. Yesterday I bought a brand new g5 from a shop and fans were not spinning until 80c from which it started spinning at 4900rpm like a vacuum. Note that I have latest bios so its not temperature table problem in bios.

I found out that there is a driver for thermal power which you can install and for most people it does the work (runs 2200 rpm silent cooling for most of time and 4900 rpm when cpu gpu temp goes above around 60c which is annoying)

So I had to spend entire day on figuring out how to control cooling fans myself. And even then dell limited available speeds in bios at 0, 2200 and 4900 rpm.

Anyways now my cooling fans run at 2200 rpm until 70c and 4900 after. So i get some nice silent performance for 90% of what I do and as for gaming, full fans after 75c is fine. I ran DOOM from steam and max temps Ive got were around 85-90c which is pretty high, so Im thinking of doing a repaste event though im afraid of voiding the warranty.

So, I just (few hours ago)made a new variable that's either brilliant or innately flawed... not sure yet. It's an oddly unique var...

__bs__

So far I only made it in python and windows env (i script like the methodology of css).

I bet you're wondering how I've defined __bs__ and the practicality of it.
__bs__ is derived from a calculated level of bullshit that annoys me to tolerate, maintain, etc. as well as things that tend to throw nonsensical errors, py crap like changing my strings to ints at seemingly random times/events/cosmic alignments/etc or other things that have a history of pulling some bs, for known or unknown reasons.

How/why did this come about now?

Well I was updating some symlinks and scripts(ps1 and bat) cuz my hdd is so close to death I'm wondering if hdd ghosts exist as it's somehow still working (even ostream could tell it should be dead, by the sound alone).

A nonsense bug with powershell allowing itself to start/run custom ps1scripts with the originating command coming from a specific batch script, which worked fine before and nothing directly connected to it has changed.

I got annoyed so took an ironic break from it to work on python crap. Python has an innately high level of bs so i did need to add some extra calculations when defining if a py script or function is actually __bs__ or just py.

The current flavour of py bs was the datetime* module... making all of my scripts using datetime have matching import statements to avoid more bs.

I've kept a log of general bs per project/use case. It's more like a warning list... like when ive spent hours debugging something by it's traceback, meticulous... to eventually find out it had absolutely nothing to do with the exception listed. Also logged aliases i created, things that break or go boom if used in certain ways, packages that ive edited, etc.

The issue with my previous logging is that it's a log... id need to read it before doing anything, no matter how quick/simple it should be, or im bound to get annoyed with... bs.

So far i have it set to alert if __bs__ is above a certain int when i open something to edit. I can also check __bs__ fot what's causing the bs. I plan to turn it into a warning and recording system for how much bs i deal with and have historical data of personal performance vs bs tolerance. There's a few other applications i think ill want to use it for, assume it's not bs itself.

*in case you prefer sanity and haven't dealt with py and datetime enough, here's the jist:
If you were to search any major forum like StackOverflow for datetime use in py, youd find things like datetime.datetime.now() and datetime.now() both used, to get the same returned value. You'll also find tons of posts for help and trying to report 'bugs', way more than average. This is because the datetime package has a name conflict... with itself. It may have been a bug several years ago, but it beeb explicitly defined as intentional since.

I am building a synth program for producing waveforms such as binaural. The programs I have used in the past have been mediocre.

In that project I am working on a realtime scope to visualize the waveforms. It is fun to learn how to streamline moving data between parts of the application. Right now it has a lot of unnecessary data copying going on, and resizing of vectors. So I am reading some books on high performance C++ to learn how to do this better. As part of this I am thinking about building a circular buffer so the vector is never resized and is always in contiguous memory.

Just plain fun!

Once a React aficionado, twice the frustration we endure,
In the realm of libraries, React's problems seem impure.
With Svelte's elegance and grace in our sight,
Let's vent about React, as day turns into night.

Boilerplate Overload, a monotonous affair,
Classes, constructors, lifecycle steps we declare.
In Svelte's simplicity, we find a breath of fresh air,
Just markup and magic – a coder's love affair.

Complex State Management, React's Achilles' heel,
Redux, Mobx, and their massive code appeal.
Svelte's state handling is a cinch, for real,
No more tangled webs of logic to conceal.

Unnecessary Re-Renders, React's performance woe,
Countless updates, like a never-ending show.
Svelte updates what's needed, like a pro,
Efficiency and speed, in its radiant glow.

Verbose Syntax, JSX's verbosity on display,
HTML in JavaScript, causing dismay.
Svelte's concise template syntax lights our way,
No more endless tags, just code that's here to stay.

Lack of Truly Reactive Behavior, React's hurdle high,
Hooks to wrangle, state to satisfy.
Svelte's reactivity, no need to question why,
It just works, oh my, oh my.

Ecosystem Complexity, React's sprawling sprawl,
Choices galore, making us bawl.
In Svelte's world, simplicity is the call,
A coherent ecosystem, it has it all.

Learning Curve, React's mountain to climb,
Classes, hooks, context, a hill of time.
Svelte's gentle curve feels sublime,
A smoother path to code, so fine.

Tooling Overkill, React's complex array,
Build tools, linters, configs in disarray.
Svelte's streamlined setup leads the way,
No more intergalactic code buffet.

Debugging Headaches, React's mysterious realm,
Complex state, intricate components overwhelm.
Svelte's predictable model, a soothing helm,
Debugging becomes a peaceful realm.

In the end, React, a complex labyrinth we explore,
Svelte's elegance and simplicity we adore.
If only React could learn, its problems to deplore,
A brighter future, for React we'd implore.

I ngl miss the thrill of high-performance computing. Or more precise would be where the program's running was directly affected by what I did.
Ever since career took the applications/apps/backend route, i try to optimise but ik it's useless.

The c#/.net would anyway make its own changes, Im not allowed to write direct SQL queries and index-powered joins coz "EF will handle it". Any JS/TS is recreated by Node

Thats how work be but kinda saddening

One of our dev team had the task to do a bulk operation for thousands of objects.
So time passes by and they implemented it. But in acceptance testing they found out that this operation takes 4 minutes for 50 objects. This is not what we call high performant when we talk about 20000 objects per bulk operation 🤔

Well, their PO asked them to solve that performance issue. And guess what, they decided on their own that the issue can be solved to reduce the bulk to 20 items so that it only takes 2 mins to run!

Really guys, is that the best you can come up with?! 😲🤬

I'm currently evaluating the best way to have both a linux distro for work and study and windows for gaming on my PC.
I need as little virtualization as possible on both systems (need to do some high performance computing and access hardware counters for uni and that sweet Ultra Raytracing 144 fps for games) and as mich flexibility in quickly switching between both systems (so dual boot isnt ideal too)
I tried WSL2 but had some issues and am currently trying out a Lubuntu VM on my windows host, but maybe someone knows the secret super cool project that magically makes this unrealistic wish work.

Design in Motion: Real-Time Rendering's Impact on Architecture

Architecture, a discipline that once relied heavily on blueprints, models, and lengthy render times, has undergone a revolutionary transformation in recent years. The advent of real-time rendering technology has fundamentally altered the way architects visualize, present, and interact with their designs. This paradigm shift has not only enhanced the creative process but has also empowered architects to make more informed decisions and create immersive experiences for clients and stakeholders.

Real-time rendering, a technological marvel that harnesses the power of high-performance graphics hardware and advanced software algorithms, allows architects to generate photorealistic visualizations of their designs in a matter of milliseconds. Gone are the days of waiting hours or even days for a single rendering to complete. This acceleration in rendering time has not only expedited the design process but has also encouraged architects to explore multiple design iterations rapidly.

One of the most significant impacts of real-time rendering on architecture is the ability to visualize a design in various lighting conditions and environmental settings. Architects can now instantly switch between daytime and nighttime lighting scenarios, experiment with different materials, and observe how their designs respond to different seasons or weather conditions. This level of dynamic visualization offers insights into how a building's appearance and functionality evolve throughout the day, contributing to more holistic and thoughtful design solutions.

Moreover, real-time rendering has transformed client presentations. Architectural concepts can now be communicated with unprecedented clarity and realism. Clients can virtually walk through spaces, observing intricate details, exploring different angles, and even experiencing the play of light and shadow in real-time. This immersive experience fosters a deeper understanding of the design intent, enabling clients to provide more targeted feedback and make informed decisions.

The impact of real-time rendering on collaboration within architectural teams cannot be overstated. Traditionally, architects and designers would need to wait for a rendering to complete before discussing design changes or improvements. With real-time rendering, team members can make adjustments on the fly, observing the immediate effects of their decisions. This seamless collaboration not only enhances efficiency but also encourages interdisciplinary collaboration as architects, engineers, and other stakeholders can work together in real-time to refine designs.

The integration of virtual reality (VR) and augmented reality (AR) into the architectural workflow is another transformative aspect of real-time rendering. Architects can now create VR environments that allow clients to step inside their designs and explore every nook and cranny. This not only enhances client engagement but also enables architects to identify potential design flaws or spatial issues that might not be apparent in 2D drawings. AR, on the other hand, overlays digital information onto the physical world, facilitating on-site decision-making and construction supervision.

Real-time rendering's impact extends beyond the design phase. It has proven to be a valuable tool for public engagement and community involvement in architectural projects. By creating virtual walkthroughs of proposed structures, architects can offer the public an opportunity to experience the design before construction begins. This transparency fosters a sense of ownership and allows for constructive feedback, contributing to the development of designs that resonate with the community's needs and aspirations.

The environmental implications of real-time rendering are also noteworthy. The ability to visualize designs in various environmental contexts contributes to more sustainable architecture. Architects can assess how natural light interacts with interior spaces, optimizing energy efficiency and reducing the need for artificial lighting during the day.

In conclusion, real-time rendering has ushered in a new era of architectural design, propelling the industry into a realm of dynamic visualization, immersive experiences, and enhanced collaboration. The ability to witness designs in motion, explore different lighting conditions, and interact with virtual environments has redefined how architects approach their craft. From facilitating client presentations to fostering sustainable design solutions, real-time rendering's impact on architecture is profound and multifaceted. As the technology continues to evolve, architects have an unprecedented opportunity to push the boundaries of creativity, efficiency, and sustainability in the built environment.

So... I've been thinking, I tend to default to LVM when trying to create easy-to-manage disk partitions, or when I want to backup a database without long lockings during a dump... Though, now... I got thinking.

What do you guys think, which is better in terms of functionality: BtrFS or LVM?

I know BtrFS offers such thing like full snapshots that allow to easily transfer just the increment over the snapshot origin off to a remote server for archival, but I never fully grew to trust btrfs as a server filesystem... Its...

Younger, and not as widespread, not to mention I don't know any performance statistics to recommend its use for this or that case (Like... Would a high-load database engine stutter flushing all those changes on disk while reading / writing temp tables and such)

Crafting Clarity: How Writing Services Improve Nursing Documentation
Effective communication is a cornerstone of quality healthcare, and nowhere is this more critical than in nursing documentation. Accurate, clear, and comprehensive documentation ensures continuity of care, supports clinical decision-making, and meets legal and regulatory requirements. However, the demands on nurses’ time and the complexity of medical information can make high-quality documentation challenging. Professional writing services offer valuable support in this area, helping nurses produce precise and reliable documentation that enhances patient care and operational efficiency.
The Importance of High-Quality Nursing Documentation
Accurate documentation provides a complete and ongoing record of a patient’s condition, treatments, and responses. This information is crucial for ensuring that all healthcare providers involved in a patient's care have the necessary details to make informed decisions. Detailed and precise documentation is a legal requirement and can be pivotal in legal cases. Proper documentation can protect nurses and healthcare institutions from liability and ensure compliance with healthcare regulations and standards.
The Role of Professional Writing Services
Professional writing services employ experts in medical writing who understand the nuances of healthcare documentation. nurse writing services ensure that records are clear, concise, and accurate, reducing the risk of misinterpretation. For instance, they can help nurses use precise medical terminology and avoid ambiguous language, ensuring that the documentation is easily understood by all healthcare providers.
Addressing Concerns and Ensuring Ethical Use
While the benefits of professional writing services are clear, some concerns must be addressed:
Confidentiality: Ensuring patient confidentiality is paramount. Reputable writing services adhere to strict privacy policies and use secure methods for handling patient information. It's essential for healthcare providers to choose writing services that prioritize confidentiality and comply with HIPAA and other relevant regulations.
Academic Integrity: For nursing students, using professional writing services ethically is important. cheap nursing writing services should be used to support learning and skill development, not to complete assignments on behalf of students. By using writing services responsibly, students can enhance their writing skills and academic performance while maintaining integrity.

No judgment regardling the "H" word here. But right now, which would you rate the best Hybrid app SDK?
Flutter, React Native, Xamarin? Other? and why?
I started using Flutter in 2020 and I'm loving the results. The learning curve is really high but the performance is nice. But coding via widgets...just feels a bit messy.
