Today, I dropped my 5900x while cleaning the computer. It's dead. pins got bent and one pin got loose.

I feel like crying... please send prayers and thoughts.

R.I.P AMD Ryzen 9 5900X 5900x 12 Cores 24 Threads 70 MB Cache 3.7 GHz up to 4.8 GHz. You will be missed.

I get a call from a client at 7 PM:
- Client: We have a business partner that just visited the website you just made for us and he said it was absolutely terrible, things are not showing up, layout is all messed up... *sends photo*. This is a VERY important new business partner and this will affect our relationship and image. Fix it NOW!
- Me: ok? I will check ... *proceed to check on several browsers and versions*
- Me: I checked on all modern browsers, cleaned cache, tried from multiple devices, it seems to be fine. What browser is your partner visiting the site from?
- Client: Idk, let me ask ...
- Client: Internet Explorer
- Me: ... that browser is not even supported anymore wth?!
- Client: We need it fixed!
- Me: ... *proceeds and hacks for IE website until 6 AM*

Well, for starters there was a cron to restart the webserver every morning.

The product was 10+ years old and written in PHP 5.3 at the time.

Another cron was running every 15 minutes, to "correct" data in the DB. Just regular data, not from an import or something.
Gotta have one of those self-healing systems I guess.

Yet another cron (there where lots) did run everyday from 02:00 to 4ish to generate the newest xlsx report. Almost took out the entire thing every time. MySQL 100%. CPU? Yes. RAM? You bet.

Lucky I wasn't too much involved at the time. But man, that thing was the definition of legacy.

Fun fact: every request was performed twice! First request gave the already logged-in client an unique access-token. Second request then processed the request with the (just issued) access-token; which was then discarded. Security I guess.

I don't know why it was build this way. It just was. I didn't ask. I didn't wanted to know. Some things are better left undisturbed. Just don't anger the machine. I became superstitious for a while. I think, in the end, it help a bit: It feels like communicating with an alien monster but all you have is a trumpet and chewing gum. Gentle does it.

Oh and "Sencha Extjs 3" almost gave me PTSD lol (it's an ancient JS framework). Followed by SOAPs WSDL cache. And a million other things.

What did the CPU Pipeline say to the System Memory?
Sorry, we only take cache.

Someone needs to take 5 minutes of their time to explain to testers what the actual fuck a "cache" is, the next time I'm receive these "urgent calls" fixable by pressing F5 I'm joining ISIS.

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 ?

The MS Teams SDK is bullshit. It's so half baked and comes with instructions like "you'll probably want a better implementation for production, good luck cause you'll have to write it yourself."

Oh and don't forget to cache your installations in a file called "notifications.json"

Deploying will create 2 app registrations (OIDC) and about 6 resources in Azure... But "you'll probably want to log to app insights in production"... So I hope you're very familiar with Bicep cause you'll have to figure out how to add that to your template properly and there are about 7 Bicep files to decipher and it doesn't create an app insights out of the box.

Probably written by an intern.

I guess crying is the equivalent of removing cache from browser, a pain relief for both of you, the computer and the human being

Hey, we need a service to resize some images. Oh, it’ll also need a globally diverse cache, with cache purging capabilities, only cache certain images in the United States, support auto scaling, handle half a petabyte of data , but we don’t know when it’ll be needed, so just plan on all of it being needed at once. It has to support a robust security profile using only basic HTTP auth, be written in Java, hosted on-prem, and be fully protected from ddos attacks. It must be backwards compatible with the previous API we use, but that’s poorly documented, you’ll figure it out. Also, it must support being rolled out 20% of the way so we can test it, and forget about it, and leave two copies of our app in production.

You can re-use the code we already have for image thumbnails even though it’s written in Python, caches nothing and is hosted in the cloud. It should be easy. This guy can show you how it all works.

WHY DOES GOOGLE CHROME CACHE THIS SHIT AND WON'T LOAD IT AGAIN. I THOUGHT I DIDN'T FIX THE BUG BUT GOOGLE CHROME IS THE BUG. THIS FLYING FUCK

CMAKE, YOU PILE OF SCRIPTING SHIT!

WHY THE FUCK CAN I NOT CHANGE MY BUILD DIRECTORY? I HAVE WASTED AN HOUR ON THIS UNBEARABLE SHITWEASEL OF AN EXCUSE FOR A BUILD SYSTEM!!!!

STOP SHITTING YOUR STUPID CACHE FILES INTO MY SOURCE FOLDER!!! AAAAAHHH!

Upscaling a prod database which was running on an 8 year old Dell desktop used as server. It had about 2MB of RAM and an Intel Core 2 processor...

This was the day I've learned a lot about querying the database as efficient as humanly possible.

The two hardest things in software are naming things, cache invalidation, and avoiding off-by-one errors.

This was originally a reply to a rant about the excessive complexity of webdev.

The complexity in webdev is mostly necessary to deal with Javascript and the browser APIs, coupled with the general difficulty of the task at hand, namely to let the user interact with amounts of data far beyond network capacity. The solution isn't to reject progress but to pick your libraries wisely and manage your complexity with tools like type safe languages, unit tests and good architecture.

When webdev was simple, it was normal to have the user redownload the whole page everytime you wanted to change something. It was also normal to have the server query the database everytime a new user requested the same page even though nothing could have changed. It was an inefficient sloppy mess that only passed because we had nothing better and because most webpages were built by amateurs.

Today webpages are built like actual programs, with executables downloaded from a static file server and variable data obtained through an API that's preferably stateless by design and has a clever stateful cache. Client side caches are programmable and invalidations can be delivered through any of three widely supported server-client message protocols. It's not to look smart, it's engineering. Although 5G gets a lot of media coverage, most mobile traffic still flows through slow and expensive connections to devices with tiny batteries, and the only reason our ever increasing traffic doesn't break everything is the insanely sophisticated infrastructure we designed to make things as efficient as humanly possible.

Powershell. Using classes. Can't create class libraries using regular .ps1 files (this way this **sort** of work). Using modules then. Can't easily refresh modules cache after any change to a class. Need restarting powrshell each time. Looking for more information. The issue is open since 2016 (just after the release of PS 5 that introduced classes). Once again, a Microsoft product turns out to be shiny at the beginning, but rusty when you go beyond the surface. Classes seem to be second class citizens in powershell. I feel frustrated and I would like to put pressure on microsoft but nobody seems to care. I'm stuck.

[Rust]
I have a bunch of computational steps in a Rust program, all very expensive. They all depend on each other, forming a cycle-free and rather small graph of dependencies which is not a tree. The results of each of them for a given input are likely used tens of times by the others, so I would like to cache the subresults dynamically.

How would I go about doing this, considering that caching (rightfully) requires mutable access to the cache and multiple operations often refer to the same subresult?

I can't ask SO because they'd just tell me to use another language or recalculate everything every time, fully convinced that difficult questions can only emerge from design mistakes.

It's 2022 and Firefox still doesn't allow deactivating video caching to disk.

When playing videos from some sites like the Internet Archive, it writes several hundreds of megabytes to the disk, which causes wear on flash storage in the long term. This is the same reason cited for the use of jsonlz4 instead of plain JSON. The caching of videos to disk even happens when deactivating the normal browsing cache (about:config property "browser.cache.disk.enable").

I get the benefit of media caching, but I'd prefer Firefox not to write gigabytes to my SSD each time I watch a somewhat long video. There is actually the about:config property "browser.privatebrowsing.forceMediaMemoryCache", but as the name implies, it is only for private browsing. The RAM is much more suitable for this purpose, and modern computers have, unlike computers from a decade ago, RAM in abundance, which is intended precisely for such a purpose.

The caching of video (and audio) to disk is completely unnecessary as of 2022. It was useful over a decade ago, back when an average computer had 4 GB of RAM and a spinning hard disk (HDD). Now, computers commonly have 16 GB RAM and a solid-state drive (SSD), which makes media caching on disk obsolete, and even detrimental due to weardown. HDDs do not wear down much from writing, since it just alters magnetic fields. HDDs just wear down from the spinning and random access, whereas SSDs do wear down from writing. Since media caching mostly invovles sequential access, HDDs don't mind being used for that. But it is detrimental to the life span of flash memory, and especially hurts live USB drives (USB drives with an operating system) due to their smaller size.

If I watch a one-hour HD video, I do not wish 5 GB to be written to my SSD for nothing. The nonstandard LZ4 format "mozLZ4" for storing sessions was also introduced with the argument of reducing disk writes to flash memory, but video caching causes multiple times as much writing as that.

The property "media.cache_size" in about:config does not help much. Setting it to zero or a low value causes stuttering playback. Setting it to any higher value does not reduce writes to disk, since it apparently just rotates caching within that space, and a lower value means that it just rotates writing more often in a smaller space. Setting a lower value should not cause more wear due to wear levelling, but also does not reduce wear compared to a higher value, since still roughly the same amount of data is written to disk.

Media caching also applies to audio, but that is far less in size than video. Still, deactivating it without having to use private browsing should not be denied to the user.

The fact that this can not be deactivated is a shame for Firefox.

Don’t you feel like development with Android Studio is 50% figuring out why the f*ck is not building, or running, resetting cache, clean build, rebuild… etc, and 50% coding? Or is it my lack of experience?

Sharing a first look at a prototype Web Components library I am working on for "fun"

TL;DR left side is pivot (grouped) table, right side is declarative code for it (Everything except the custom formatting is done declaratively, but has the option to be imperative as well).

====

TL;DR (Too long, did read):

I'm challenging myself to be creative with the cool new things that browsers offer us. Lani so far has a focus on extreme extensibility, abstraction from dependencies, and optional declarative style.

It's also going to be a micro CSS framework, but that's taking the back-seat.

I wanted to highlight my design here with this table, and the code that is written to produce this result.

First, you can see that the <lani-table> element is reading template, data, and layout information from its child elements. Besides the custom highlighting code (Yellow background in the "Tags" column, and green gradient in the "Score" column), everything can be done without opening even a single script tag.

The <lani-data-source> element is rather special. It's an abstraction of any data source, and you, as a developer can add custom data sources and hook up the handlers to your whim (the element itself uses the "type" attribute to choose a handler. In this case, the handler is "download" which simply sends a fetch request to the server once and downloads the result to memory).

Templates are stored in an html file, not string literals (Which I think really fucks the code) and loaded async, then cached into an object (so that the network tab doesn't get crowded, even if we can count on the HTTP cache). This also has the benefit of allowing me to parse the HTML templates once and then caching the parsed result in memory, so templates are never re-parsed from string no matter how many custom elements are created.

Everything is "compiled" into a single, minified .js file that you include on your page.

I know it's nothing extraordinary, but for something that doesn't need to be compiled, transpiled, packaged, shipped, and kissed goodnight, I think it's a really nice design and I hope to continue work on it and improve it over time

devranton stopit get some help

Lessions I learned so far from my first big node/npm project with tons of users:
1) If you didn't build something for a while, expect 3 hours of resolving version conflicts for every two weeks since the last build.
2) Even if the tests pass, run the containers on your own machine and make sure that the app doesn't randomly crash before deploying
3) Even if the app seemed to work on your own machine, run the tests again in an environment mimicking prod at most 15 minutes before replacing the running containers.
4) Even if all else indicates that the app will work, only ever deploy if you expect to be available within the 4 hours following a deployment.
5) Don't use shrinkwrap for anything other than locking every version down completely. A partial shrinkwrap will produce bugs that are dependent on the exact hour you built the app _and_ the shrinkwrap file, and therefore no one will ever have seen them other than you.
6) Avoid gyp, and generally try not to interface too much with anything that doesn't run on node. If parts of your solution use very different toolchains, your problems will be approximately proportional to the amount of code. And you'd be surprised just how much code you're running. (otherwise it's more logarithmic because the more code the less likely a new assumption is unique)
7) Do not update webpack or its plugins or anything they might call unless you absolutely need to
8) Containers are cool but the alpine ones are pretty much useless if you have even just one gyp module.
9) There's always another cache. To save yourself a lot of pain, include the build time in every file or its name that the browser can download, and compare these to a fresh build while debugging to assert that the bug is still present in the code you're reading
+1) Although it may look like it, SQLite is far from a simple solution because the code and the bindings aren't maintained. In fact, it'll probably be more time consuming than using a proper database.

People : We have cache problems, nothing works !

Me looking at 2 GB cache : Well, ok here you go : (Screen)

Play Store's $25 registration fee - for getting PWA listed in their shitty catalogue? Who in the right mind would even jump in this clusterfuck of store to find a *web* app? For all you know, Google, there is such thing as QR codes - and customers can just scan the code (or type in that sweet address). Voila! Boom!!! Ching-ching!

Hello-hello, monopolistic cashgrabage! I came to inform you that your TWA bullshit is unneeded in ETHICAL space. The only ones who would benefit from this thing are permission-hungry publishers. And I'm already sick of this culture where people are put into store bubbles. You can't hide the fact that this data and features you provide, with "native" layer, may be misused in a jiffy - and by big players, no less. Of course, as a vile dumpster that you are, you don't mind it.

Don't even bring up a battery consumption that comes with PWA and browser. This doesn't matter if you use an app for some 2 minutes to tick your mental checkboxes! I'm just sick of app stores and native apps that collect the data without normal warning, and dare to take more than 1 second to fucking load the cached data. Take a lesson or two from PWAs that collect (probably useful) cache, instead of my specs, and load almost instantly.

Any recommended free Mac App Uninstaller which uninstalls the app completly including any preferences and cache?

How to Fix Sidebar Below Content Error in WordPress?

Fixing The Sidebar Below The Content Error in WordPress
Undo recent changes to your WordPress theme.
Rule out WordPress plugins.
Find the HTML breaking the layout.
Find the CSS moving the sidebar below the content.
Clear WordPress cache.

Disconnect from everything that you're thinking of for a moment. Step away from your computer, and dump all of your thoughts out for about five minutes.
In better terms: clear your cache. Your devices need it, and you need it too. Bonus points if you give your eyes a stretch and look outside your window.

I have two laravel apps. Both sharing one redis db. One has App/Post one has App/Models/Blog/Post. When I unserialize models from redis cache saved by the other app I get issues because it cannot find the right model to hydrate.

How would you build a custom map to get the right model?

Who asked for RedDatabase and RedXpert? You guessed it - nobody 😑 It's a buggy Firebird and DBeaver domestic knock-off!

My student was assigned with making Flask app by "simple" requirements. But guess what? We can't figure out hecking RedDatabase?! Figures out that they sent incompatible *.fdb database file, on which we wasted entire 3 hours troubleshooting obscure error, while clean database doesn't cause any trouble.

Last error that completely drained us is following:
"""
Reason: unsupported on-disk structure for file /var/rdb/test.fdb; found 12.3, support 12.2; IProvider::attachDatabase failed when loading mapping cache [SQLState:HY000, ISC error code:335544379]
"""

So now, he basically recreates database by scheme on image. What also shady seems to me is that application also has to deployed on virtual OS which he can bring on USB stick or by cloud later.

Here's a daft thing: a lot of browsers, typically on phones and Macs, won't re-download a file if it's been downloaded before. I can understand caching pages, images and CSS, that's good, but caching downloaded files? Meaning that when a user clicks to download a Word doc or a PDF, the browser will decide that they don't need to! Even though they think they do! I'm now having to add ?v=time() to PDFs, Excel files and similar, which feels really hacky. Some browsers will ask if the user wants to re-download, which is fine, but taking people to old and obsolete versions of documents when they want the current version is just stoooooopid.

I hate group project so much.

I yet again successfully stirred up a big drama in my project group. For project, I proposed a CDN cache system for a post only database server. Super simple. I wanted to see what ideas other people come up with. So I said I am not good at the content and the idea is dumb. Oh man, what a horrible mistake. One group member wants to build a chat app with distributed storage. We implemented get/put for a terribly designed key value store and now they want to build a freaking chat app on top of a more stupid kV store using golang standard lib. I don't think any of those fools understand the challenges that comes with the distributed storage.

I sent a video explaining part of crdt. "That's way too complicated. Why are you making everything complicated."

Those fools leave too much details for course stuff's interpretation and says

"course stuff will only grade the project according to the proposal. It's in the project description".

I asked why don't they just take baby steps and just go with their underlying terribly designed kV store.

"Messaging app is more interesting and designing kV store with generic API is just as difficult"

😂 Fucking egos

Then I successfully pissed off all group members with relatively respectful words then pissed off myself and joined another group.

#Suphle Rant 3: Road to PHP8, Flow travails

Some primer: Flows is a feature that causes the framework to bypass handling the request now but read it from cache. This cache entry is meant to be populated without warming, based on the preceding request. It's sort of like prefetching but done on the back end

While building Suphle, I made some notes on some chapters about caveats and gotchas I may forget while documenting. One such note was that when users make the Flow request, the framework will attempt to determine who user is, using authentication mechanism defined on the first module (of the modular monolith)

Now, I got to this point during documentation and started wondering whether it's impossible for the originating request to have used a different authentication mechanism, which would result in an empty entry for returning user. I *think* it's possible cuz I've got something else called "route mirroring", where web based routes can be converted to API routes. They'll then return JSON, get served under defined API path, use JWT, all automatically. But I just couldn't connect the dots for the life of me, regarding how any of this could impact authentication on the Flow request

While trying to figure out how to write the test for this or whether it was even necessary (since I had no use case), it struck me that since Flow requests are not triggered by an actual user, any code attempting to read authenticated user will see nothing!

I HATE it when I realize there's ambiguity or an oversight, after the amount of attention and suffering devoted. This, along with a chain of personal troubles set off despondency for a couple of days. No appetite for food or talk. Grudgingly refactored in this update over some days. Wrote some tests, not all passed. More pain. May have to convert them to unit tests

For clarity, my expectation is, I built this. Nothing should be impossible for me

Surprisingly, I caught a somewhat lucky break –an ex colleague referred me to the 1st gig I'm getting in 1+ year. It's about writing a plugin for some obscure forum software. I'm not too excited cuz it's poorly documented and I'll have to do a lot of groping, they use arrays instead of objects etc. There's no guarantee I'll find how to implement all client's requirements

While brooding last night, surfing the PHP subreddit, stumbled on a post about using Rector to downgrade a codebase. I've always been interested in the reverse but didn't have any incentive to fret over it. Randomly googled and saw a post promising a codebase can be upgraded with 3 commands in 5 minutes to PHP 8. Piqued my interest around 12:something AM. Stayed up all night upgrading it, replacing PHPSTAN with Psalm, initializing the guy's project, merging Flow auth with master etc. I think it may have taken 5 minutes without the challenge of getting local dev environment to PHP 8

My mood is much lighter than it was, although the battle is not won yet –image tests are failing. For some weird reason, PHP8 can't read generated test images. Hope I can ride on that newfound lease on life to study the forum and get the features working

I have some other rant but this is already a lot to digest in one sitting. See you in rant #4

I'm building a script parser to make mods for a game I like. The first step is to write an importer.

The documentation is nonexistent and I'm delving into byte manipulation, which I'm not familiar with - at all. I'm porting existing code from Java to C#, and everything is similar but different enough that I can't always just to a 1:1 transfer.

I get everything working, cleaned up and split into classes so I can write the exporter.

I do an import and the file won't parse. I try all previously know working files and still no good. I clean, rebuild, clean rebuild, run, debug, restart my computer, clear my cache, clean, rebuild. No good.

IT WAS WORKING 5 MINUTES AGO

Proceed to revert to every version from the last hour. No dice.

I was in the wrong folder the whole time.

Navigate to the proper folder, open the filename I know to be good and bingo, works like a charm.

The same project caused me headaches because I had a "== -1", when it should have been "== 1". Between my inexperience with byte manipulation and my untreated astigmatism, I was nearly sent to the shadow realm fixing that.

On my imac when i open youtube video it loads for the first 10-17 seconds fine and then freezes. When I try to fast forward it freezes. The pages break and crash. Comments wont load at all. I tried clearing cache reinstalling Google chrome browser restarting pc etc and nothing worked. It plays fine in incognito mode but not in regular chrome mode. WTF??? Please help!!!

I'm the only one here who cares little about hardware?
I hear people (even non IT ones) spending months in comparing computers and reading any technical spec (cache size, RAM frequency...) before buying one while I just give a glance to the main specs (CPU, RAM, GPU) and if they're decent enough and I like the price I buy, once I even bought a laptop while half drunk and I haven't regretted the purchase.

Question about cache (Redis or other distribuated cache).
So I would like to find a solution with “Partioning”. But without code it my self (ofc)
Ok, example :
In the application you have clients, each client has users, each user has role.
So right now it’s in the cache with the keu “User:<userId>” = role
Sometimes, when you change client settings, all entries should be removed.
So what I would love to have :
Client_Id/UsersRoles/UserId as a key
And I would love to be able tp delete “all keys after /” :
Basiclly delete client_id/ would delete everything in cache for this client
Delete client_id/UserRoles will clean up all saved roles.
I’m pretty new working with redis, but it doesn’t seem possible out of the box.
Any reading material I could read ?
