Client comes to me after a year to publish an update to his app.

I accept, start looking for my release key.... Found it.

Fuuuuuuucccck what's the password? I can't remember

Googled what to do if forgot password of keystore: Nope can't do shit other than brute Force. You've to forget your app and publish as a new app. Nice.

I must have written it somewhere... I'm sure. Check my password manager: Nope.

Start brute forcing:
Default pass: android. Nope
Name of app? Nope

After 10 mins of brute forcing:
Why would I not store the password in my password manager? The only reason I can think is the password is too stupid to be stored.

Try "password". App signed successfully.

I'm ashamed of 1 year older me xD

My first AI program in the 1985 on Apple IIe (64kb ram computer) was answering simple questions with yes and no. Everyone were shocked with precision of about 100% when I was typing and 70-80% when others were typing. My parents were scared and skeptical. How it works? Store the time between the first key pressure and the following, when it is larger than 1 second the answer is yes, otherwise no. They say the question, you know the answer and type accordingly. When they want to write the question themselves, you try to force their typing speed if possible. I was 12 years old and it was very funny.

My first Windows rant.

I use Spotify heavily. (After all, I am paying for it every fucking month.) In fact, it's safe to say I use it upwards of 12+ hours a day.

My birthday was a few weeks ago. I got a new mechanical keyboard using some money i received as a gift. This keyboard has a function key to launch your media player. Odd function in my opinion. But I figured I would try it out for a week or so.

My problem is: the default media center is that god forsaken piece of shit groove music (not only is it shit, I also have 0 mp3 files on my computer).

No problem, I'll just change the default media center. Fucking Windows doesn't let me change it to Spotify. Odd. Well, I did download it from Spotify's website. Let's try downloading it from the Windows store.

I download Spotify from the Windows store. It still cannot be set to the default media center.

For fuck sake, if Google can let me set Spotify as my default over their shitty YouTube Music that I know damn well they're trying to make as the default for all Android, then you can let me change it Windows.

Yes, I know Spotfiy isn't exactly a media center, but it's basically the same fucking thing.

The solution for this one isn't nearly as amusing as the journey.

I was working for one of the largest retailers in NA as an architect. Said retailer had over a thousand big box stores, IT maintenance budget of $200M/year. The kind of place that just reeks of waste and mismanagement at every level.

They had installed a system to distribute training and instructional videos to every store, as well as recorded daily broadcasts to all store employees as a way of reducing management time spend with employees in the morning. This system had cost a cool 400M USD, not including labor and upgrades for round 1. Round 2 was another 100M to add a storage buffer to each store because they'd failed to account for the fact that their internet connections at the store and the outbound pipe from the DC wasn't capable of running the public facing e-commerce and streaming all the video data to every store in realtime. Typical massive enterprise clusterfuck.

Then security gets involved. Each device at stores had a different address on a private megawan. The stores didn't generally phone home, home phoned them as an access control measure; stores calling the DC was verboten. This presented an obvious problem for the video system because it needed to pull updates.

The brilliant Infosys resources had a bright idea to solve this problem:

- Treat each device IP as an access key for that device (avg 15 per store per store).
- Verify the request ip, then issue a redirect with ANOTHER ip unique to that device that the firewall would ingress only to the video subnet
- Do it all with the F5

A few months later, the networking team comes back and announces that after months of work and 10s of people years they can't implement the solution because iRules have a size limit and they would need more than 60,000 lines or 15,000 rules to implement it. Sad trombones all around.

Then, a wild DBA appears, steps up to the plate and says he can solve the problem with the power of ORACLE! Few months later he comes back with some absolutely batshit solution that stored the individual octets of an IPV4, multiple nested queries to the same table to emulate subnet masking through some temp table spanning voodoo. Time to complete: 2-4 minutes per request. He too eventually gives up the fight, sort of, in that backhanded way DBAs tend to do everything. I wish I would have paid more attention to that abortion because the rationale and its mechanics were just staggeringly rube goldberg and should have been documented for posterity.

So I catch wind of this sitting in a CAB meeting. I hear them talking about how there's "no way to solve this problem, it's too complex, we're going to need a lot more databases to handle this." I tune in and gather all it really needs to do, since the ingress firewall is handling the origin IP checks, is convert the request IP to video ingress IP, 302 and call it a day.

While they're all grandstanding and pontificating, I fire up visual studio and:

- write a method that encodes the incoming request IP into a single uint32
- write an http module that keeps an in-memory dictionary of uint32,string for the request, response, converts the request ip and 302s the call with blackhole support
- convert all the mappings in the spreadsheet attached to the meetings into a csv, dump to disk
- write a wpf application to allow for easily managing the IP database in the short term
- deploy the solution one of our stage boxes
- add a TODO to eventually move this to a database

All this took about 5 minutes. I interrupt their conversation to ask them to retarget their test to the port I exposed on the stage box. Then watch them stare in stunned silence as the crow grows cold.

According to a friend who still works there, that code is still running in production on a single node to this day. And still running on the same static file database.

Today I learned the hard way that losing your app's key store means no more updating , bug fixing , performance boosting , features adding ...
The app had like 5k downloads on the play store ..
Lost the key when one of my hard drives burned ..
Lesson of the day : keep your keys safe .
*trying to stay strong*

So I Bought this bio metric pad lock for my daughter. She excitedly tried to set it up without following the directions( they actually have good directions on line) first thing you do is set the "master print" she buggered that up setting her print. So when I got home I was thinking, no problem I'll just do a reset and then we cant start again.

NOPE !!! you only have one chance to set the master print! after that if you want to reset the thing you need to use the master print along with a physical key that comes with it.

What sort if Moron designs hardware / software that is unable to be reset. Imagine how much fun it would be if once you set your router admin password it was permanent unless you can long back in to change it. Yea nobody has ever forgotten a password.

Well they are about to learn a valuable financial lesson about how user friendly design will influence your bottom line. people (me) will just return the lock to the store where they bought it, and it will have to be shipped back to the factory and will be very expensive for them paying for all of the shipping to and from and resetting and repackaging of the locks and finally shipping again to another store. Meanwhile I'll keep getting new locks until at no cost until she gets it right.

poor design

At an auto parts store and was taking a look at the UI.

I FOUND A DINOSAUR!

More realistically I saw F20 as a shortcut key. How I know it wasn’t a typo? There was also F16. Wow. Even their keyboard stop at F12.

Talk about legacy program.

I grew up on a farm in western KS. My parents bought PCs when I was in grade school. First was a trs80 , then an Epson Equity 1+, where I built a spare key for it, and built levels in willy for my brother to beat. Then a 486 and pentium which I broke often. I ended up working at the same store in college for extra cash. While I'm an adverage developer, I do on and make decent $$. I still help them out with keeping their PCs running, for moms sewing, and dads Linux box. I figure I owe them for their investment in me. They gave me the tools to figure out what I want to do with my career and my life.

Want to make someone's life a misery? Here's how.

Don't base your tech stack on any prior knowledge or what's relevant to the problem.

Instead design it around all the latest trends and badges you want to put on your resume because they're frequent key words on job postings.

Once your data goes in, you'll never get it out again. At best you'll be teased with little crumbs of data but never the whole.

I know, here's a genius idea, instead of putting data into a normal data base then using a cache, lets put it all into the cache and by the way it's a volatile cache.

Here's an idea. For something as simple as a single log lets make it use a queue that goes into a queue that goes into another queue that goes into another queue all of which are black boxes. No rhyme of reason, queues are all the rage.

Have you tried: Lets use a new fangled tangle, trust me it's safe, INSERT BIG NAME HERE uses it.

Finally it all gets flushed down into this subterranean cunt of a sewerage system and good luck getting it all out again. It's like hell except it's all shitty instead of all fiery.

All I want is to export one table, a simple log table with a few GB to CSV or heck whatever generic format it supports, that's it.

So I run the export table to file command and off it goes only less than a minute later for timeout commands to start piling up until it aborts. WTF. So then I set the most obvious timeout setting in the client, no change, then another timeout setting on the client, no change, then i try to put it in the client configuration file, no change, then I set the timeout on the export query, no change, then finally I bump the timeouts in the server config, no change, then I find someone has downloaded it from both tucows and apt, but they're using the tucows version so its real config is in /dev/database.xml (don't even ask). I increase that from seconds to a minute, it's still timing out after a minute.

In the end I have to make my own and this involves working out how to parse non-standard binary formatted data structures. It's the umpteenth time I have had to do this.

These aren't some no name solutions and it really terrifies me. All this is doing is taking some access logs, store them in one place then index by timestamp. These things are all meant to be blazing fast but grep is often faster. How the hell is such a trivial thing turned into a series of one nightmare after another? Things that should take a few minutes take days of screwing around. I don't have access logs any more because I can't access them anymore.

The terror of this isn't that it's so awful, it's that all the little kiddies doing all this jazz for the first time and using all these shit wipe buzzword driven approaches have no fucking clue it's not meant to be this difficult. I'm replacing entire tens of thousands to million line enterprise systems with a few hundred lines of code that's faster, more reliable and better in virtually every measurable way time and time again.

This is constant. It's not one offender, it's not one project, it's not one company, it's not one developer, it's the industry standard. It's all over open source software and all over dev shops. Everything is exponentially becoming more bloated and difficult than it needs to be. I'm seeing people pull up a hundred cloud instances for things that'll be happy at home with a few minutes to a week's optimisation efforts. Queries that are N*N and only take a few minutes to turn to LOG(N) but instead people renting out a fucking off huge ass SQL cluster instead that not only costs gobs of money but takes a ton of time maintaining and configuring which isn't going to be done right either.

I think most people are bullshitting when they say they have impostor syndrome but when the trend in technology is to make every fucking little trivial thing a thousand times more complex than it has to be I can see how they'd feel that way. There's so bloody much you need to do that you don't need to do these days that you either can't get anything done right or the smallest thing takes an age.

I have no idea why some people put up with some of these appliances. If you bought a dish washer that made washing dishes even harder than it was before you'd return it to the store.

Every time I see the terms enterprise, fast, big data, scalable, cloud or anything of the like I bang my head on the table. One of these days I'm going to lose my fucking tits.

XCode you fucking piece of shit...

So I just wanted to process my ios app to the app store and start the archive process. All of the sudden:
Command CodeSign failed with a nonzero exit code

What? So there is an error and you cannot tell me the error code? All information you give me that it isn't zero!? Wow... Amazing... What a great user experience. Maybe it cannot resolve the error? Maybe it is some external tool Apple has no access to and that is the only valid error they can throw at us?

Oh hell no! It has something to do with the keychain access! But why tell the user? That wouldn't be as much fun as just tell it is a nonzero error, isn't it apple?!

In the end locking and unlocking my key chain solved the problem... Thanks for nothing XCode!

Dear theme designers, unless you are designing an app specifically with OLED in mind... Do not use black as a main background colour.

It just looks horrible IMO, key example on good dark theme is the windows store and a example of horrible dark theming is the settings app.

And mini rant over.

There's very little good use cases for mongo, change my mind.

Prototyping maybe? Rails can prototype, create/update/destroy db schemas really quickly anyways.

If you're doing a web app, there's tons of libs that let you have a store in your app, even a fake mongo on the browser.

Are the reads fast? When I need that, use with redis.

Can it be an actual replacement for an app's db? No. Safety mechanisms that relational dbs have are pretty much must haves for a production level app.
Data type checks, null checks, foreign key checks, query checks.
All this robustness, this safety is something critical to maintain the data of an app sane.

Screw ups in the app layer affecting the data are a lot less visible and don't get noticed immediately (things like this can happen with relational dbs but are a lot less likely)

Let's not even get into mutating structures. Once you pick a structure with mongo, you're pretty much set.
Redoing a structure is manual, and you better have checks afterwards.

But at the same time, this is kind of a pro for mongo, since if there's variable data, as in some fields that are not always present, you don't need to create column for them, they just go into the data.

But you can have json columns in postgres too!

Is it easier to migrate than relational dbs? yes, but docker makes everything easy also.

# NEED SUGGESTIONS

I am working on a secure end to end encrypted note taking web application. I am the sole developer and working on weekends and will make it open source.

The contents you save will be end to end encrypted, and server won't save the key, so even I can't read or NSA or CIA.

So I wanted to know if the idea is good? There are lot of traditional note sharing apps like Google Keep and Evernote. But they store your stuff in plaintext. So as a user will u switch to this secure solution?

I just got my third 128GB MicroSD card off Amazon, this time SanDisk. Yet again, trying to do anything not involving the OEM full-disk exFAT partition staying intact (which, fuck that, all that uses that is Windows and Linux, i'm looking for splitting this thicc bih up) shifts EVERYTHING, including MBR+PT/GPT down the disk by 16MB exactly inserting data from... the atmosphere? whatever's using it? ...do SD cards have that secure key/DRM store space thing still?

(EDIT: I do verify that they ARE genuinely the right size after purchasing before reformatting or repartitioning, by the way.)

First it was a Silicon Power card, then a Samsung card, now a SanDisk.

(Also, why all S?)

Luckily, this time it wasn't a pain in the ass to get it to read as anything but "Bad Card" or a 0-byte/empty/non-existent device in Windows/Linux (respectively) so I was able to see that it was indeed the same issue without taking 3 days to jump through device hoops to finally get it to do it again but in such a way that it shifts out and back in all zeroes.

I had a booth at a small event to represent my business. I had prepared a web-based game for people to play to win a prize. I had it running on a PC mirrored on a TV so I could do my work on my Mac separately between visitors.

During a speaker’s presentation, someone bored with it came up to my booth and I introduced her to the game. She started playing it but the sound was up too loud and drew attention to her. I quickly used volume key on the top row, but nothing happened. So I thought the fn key needed to be pressed and held to change the volume. Nope. Then I thought I’ll just use the volume control in the dock. But the browser was full screen, and when I tried to quickly change that, some other unknown thing happened and some other stupid MS configuration screen filled the screen. She gave up trying to play at that point and I felt super stupid.

When did it become so hard to use Windows machines and software? I’ve been on a Mac for about 8 years now and using this Windows laptop just feels ridiculous to me. Like some broken toy that came from a bargain bin at a dollar store. The whole thing feels cheap and like it’ll break in half if I twist it accidentally. Other Windows laptops I look at in the stores occasionally just don’t measure up in build quality. Like the companies know you’ll get max 2 years useful life and throw it away.

StackOverflow locked my account. I'm hoping someone here might be kind enough to help me with a bash script I'm "bashing" my head with. Actually, it's zsh on MacOS if it makes any difference.

I have an input file. Four lines. No blank lines. Each of the four lines has two strings of text delimited by a tab. Each string on either side of the tab is either one word with no spaces or a bunch of words with spaces. Like this (using <tab> as a placeholder here on Devrant for where the tab actually is)

ABC<tab>DEF
GHI<tab>jkl mno pq
RST<tab>UV
wx<tab>Yz

I need to open and read the file, separate them into key-value pairs, and put them into an array for processing. I have this script to do that:

# Get input arguments
search_string_file="$1"
file_path="$2"

# Read search strings and corresponding names from the file and store in arrays
search_strings=()
search_names=()

# Read search strings and corresponding names from the file and store in arrays
while IFS= read -r line || [[ -n "$line" ]]; do
echo "Line: $line"
search_string=$(echo "$line" | awk -F'\t' '{print $1}')
name=$(echo "$line" | awk -F'\t' '{print $2}')
search_strings+=("$search_string")
search_names+=("$name")
done < "$search_string_file"

# Debug: Print the entire array of search strings
echo "Search strings array:"
for (( i=0; i<${#search_strings[@]}; i++ )); do
echo "[$i] ${search_strings[$i]} -- ${search_names[$i]}"
done

However, in the output, I get the following:

Line: ABC<tab>DEF
Line: GHI<tab>jkl mno pq
Line: RST<tab>UV
Line: wx<tab>Yz
Search strings array:
[0] --
[1] ABC -- DEF
[2] GHI -- jkl mno pq
[3] RST -- UV

That's it. I seem to be off by one because that last line...

Line: wx<tab>Yz

never gets added to the array. What I need it to be is:

[0] ABC -- DEF
[1] GHI -- jkl mno pq
[2] RST -- UV
[3] wx -- Yz

What am I doing wrong here?

Thanks.

So just now I had to focus on a VM running in virt-manager.. common stuff, yeah. It uses a click of le mouse button to focus in, and Ctrl-Alt-L to release focus. Once focused, the VM is all there is. So focus, unfocus, important!

Except Mate also uses Ctrl-L to lock the screen. Now I actually don't know the password to my laptop. Autologin in lightdm and my management host can access both my account and the root account (while my other laptop uses fingerprint authentication to log in, but this one doesn't have it). Conveniently my laptop can also access the management host, provided a key from my password manager.. it makes more sense when you have a lot of laptops, servers and other such nuggets around. The workstations enter a centralized environment and have access to everything else on the network from there.

Point is, I don't know my password and currently this laptop is the only nugget that can actually get this password out of the password store.. but it was locked. You motherfucker for a lock screen! I ain't gonna restart lightdm, make it autologin again and lose all my work! No no no, we can do better. So I took my phone which can also access the management host, logged in as root on my laptop and just killed mate-screensaver instead. I knew that it was just an overlay after all, providing little "real" security. And I got back in!

Now this shows an important security problem. Lock screens obviously have it.. crash the lock screen somehow, you're in. Because behind that (quite literally) is your account, still logged in. Display managers have it too to some extent, since they run as root and can do autologin because root can switch user to anyone else on the system without authentication. You're not elevating privileges by logging in, you're actually dropping them. Just something to think about.. where are we just adding cosmetic layers and where are we actually solving security problems? But hey, at least it helped this time. Just kill the overlay and bingo bango, we're in!

So... I’ve recently started a new role, and luckily I’ve established myself as someone that knows his shit (more or less) TM.

I’m leading the charge on tech debt, and raising issues about it, first on my radar is the monstrosity of their approach to app config.

It’s a web app, and they store config in a key-value table in the database.

Get this. The key is the {type}.{property} path and this is fetched from the database and injected *at construction* via reflection.

Some of these objects get instantiated dozens of times per-request. Eurgh.

Can anyone help me with this theory about microprocessor, cpu and computers in general?

( I used to love programming when during school days when it was just basic searching/sorting and oop. Even in college , when it advanced to language details , compilers and data structures, i was fine. But subjects like coa and microprocessors, which kind of explains the working of hardware behind the brain that is a computer is so difficult to understand for me 😭😭😭)

How a computer works? All i knew was that when a bulb gets connected to a battery via wires, some metal inside it starts glowing and we see light. No magics involved till now.

Then came the von Neumann architecture which says a computer consists of 4 things : i/o devices, system bus ,memory and cpu. I/0 and memory interact with system bus, which is controlled by cpu . Thus cpu controls everything and that's how computer works.

Wait, what?
Let's take an easy example of calc. i pressed 1+2= on keyboard, it showed me '1+2=' and then '3'. How the hell that hapenned ?

Then some video told me this : every key in your keyboard is connected to a multiplexer which gives a special "code" to the processer regarding the key press.
The "control unit" of cpu commands the ram to store every character until '=' is pressed (which is a kind of interrupt telling the cpu to start processing) . RAM is simply a bunch of storage circuits (which can store some 1s) along with another bunch of circuits which can retrieve these data.

Up till now, the control unit knows that memory has (for eg):
Value 1 stored as 0001 at some address 34A
Value + stored as 11001101 at some address 34B
Value 2 stored as 0010 at some Address 23B

On recieving code for '=' press, the "control unit" commands the "alu" unit of cpu to fectch data from memory , understand it and calculate the result(i e the "fetch, decode and execute" cycle)

Alu fetches the "codes" from the memory, which translates to ADD 34A,23B i.e add the data stored at addresses 34a , 23b. The alu retrieves values present at given addresses, passes them through its adder circuit and puts the result at some new address 21H.

The control unit then fetches this result from new address and via, system busses, sends this new value to display's memory loaded at some memory port 4044.
The display picks it up and instantly shows it.

My problems:
1. Is this all correct? Does this only happens?

2. Please expand this more.
How is this system bus, alu, cpu , working?
What are the registers, accumulators , flip flops in the memory?
What are the machine cycles?
What are instructions cycles , opcodes, instruction codes ?
Where does assembly language comes in?
How does cpu manipulates memory?
This data bus , control bus, what are they?
I have come across so many weird words i dont understand dma, interrupts , memory mapped i/o devices, etc. Somebody please explain.

Ps : am learning about the fucking 8085 microprocessor in class and i can't even relate to basic computer architecture. I had flunked the coa paper which i now realise why, coz its so confusing. :'''(

The importance of not using static salt / IVs.

I've been working on a project that encrypts files using a user-provided password as key. This is done on the local machine which presents some challenges which aren't present on a hosted environment. I can't generate random salt / IVs and store them securely in my database. There's no secure way to store them - they would always end up on the client machine in plain text.

A naive approach would be to use static data as salt and IV. This is horrendously harmful to your security for the reason of rainbow tables.

If your encryption system is deterministic in the sense that encrypting / hashing the same string results in the same output each time, you can just compile a massive data set of input -> output and search it in no time flat, making it trivial to reverse engineer whatever password the user input so long as it's in the table.

For this reason, the IVs and salt are paramount. Because even if you generate and store the IVs and salt on the user's computer in plaintext, it doesn't reveal your key, but *does* make sure that your hashing / encryption isn't able to be looked up in a table

Noob question

I’m trying to deploy my front end web app (my personal website) to GitHub pages.

In my app, I used react environment variables to store a api key I need in my app.

When I deploy my app with GitHub pages, will the app still be able to access the react env variables?

Let me know if that doesn’t make sense. Thanks!

Opinions please.

I want to share a small model in my iOS app. Now on android I'd do with with ViewModelProviders, but on iOS I'm going with SharedDataContainer which is basically a singleton class that store key value data.

Is there any better approach? Data will not be bigger than 10 list items with guid (key) and int (value)

However; when I have big data I do cache on disk or hello OOM exceptions (or whatever they call that bitch on iOS)

Chinese remainder theorem

So the idea is that a partial or zero knowledge proof is used for not just encryption but also for a sort of distributed ledger or proof-of-membership, in addition to being used to add new members where additional layers of distributive proofs are at it, so that rollbacks can be performed on a network to remove members or revoke content.

Data is NOT automatically distributed throughout a network, rather sharing is the equivalent of replicating and syncing data to your instance.
Therefore if you don't like something on a network or think it's a liability (hate speech for the left, violent content for the right for example), the degree to which it is not shared is the degree to which it is censored.

By automatically not showing images posted by people you're subscribed to or following, infiltrators or state level actors who post things like calls to terrorism or csam to open platforms in order to justify shutting down platforms they don't control, are cut off at the knees. Their may also be a case for tools built on AI that automatically determine if something like a thumbnail should be censored or give the user an NSFW warning before clicking a link that may appear innocuous but is actually malicious.

Server nodes may be virtual in that they are merely a graph of people connected in a group by each person in the group having a piece of a shared key.
Because Chinese remainder theorem only requires a subset of all the info in the original key it also Acts as a voting mechanism to decide whether a piece of content is allowed to be synced to an entire group or remain permanently.

Data that hasn't been verified yet may go into a case for a given cluster of users who are mutually subscribed or following in a small world graph, but at the same time it doesn't get shared out of that subgraph in may expire if enough users don't hit a like button or a retain button or a share or "verify" button.

The algorithm here then is no algorithm at all but merely the natural association process between people and their likes and dislikes directly affecting the outcome of what they see via that process of association to begin with.

We can even go so far as to dog food content that's already been synced to a graph into evolutions of the existing key such that the retention of new generations of key, dependent on the previous key, also act as a store of the data that's been synced to the members of the node.

Therefore remember that continually post content that doesn't get verified slowly falls out of the node such that eventually their content becomes merely temporary in the cases or index of the node members, driving index and node subgraph membership in an organic and natural process based purely on affiliation and identification.

Here I've sort of butchered the idea of the Chinese remainder theorem in shoehorned it into the idea of zero knowledge proofs but you can see where I'm going with this if you squint at the idea mentally and look at it at just the right angle.

The big idea was to remove the influence of centralized algorithms to begin with, and implement mechanisms such that third-party organizations that exist to discredit or shut down small platforms are hindered by the design of the platform itself.

I think if you look over the ideas here you'll see that's what the general design thrust achieves or could achieve if implemented into a platform.

The addition of indexes in a node or "server" or "room" (being a set of users mutually subscribed to a particular tag or topic or each other), where the index is an index of text audio videos and other media including user posts that are available on the given node, in the index being titled but blind links (no pictures/media, or media verified as safe through an automatic tool) would also be useful.

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.

Had that moment where I thought to myself I need some sleep.
Working on Android app, using shared preferences (for a lay person, a key value store for settings)
Kept storing data in store and checked repeatedly from different parts of the app for the data. No clue where it went when storing (did store correctly)

Found out I was storing in a store labelled X _Y and was reading from store called XY.

I identified the need for a product akin to an ORM that maps an algebraic type system such as that of Rust to a key-value database (my situation dictates lmdb but I'd like to abstract away the store). Can you recommend prior art for me to research?

PrestaShop irony:
* Theirs modules have >3500 lines per class (eg. blocklayered.php)
* Theirs controllers have > 5000 lines and contains a LOT of html code inside

AND when I tried to add own module to theirs addons store they declined it because:
* I had unused $key var in foreach and this is "bad practice" as I was told

* In one hook I was returning 1 line of html code (i had to add global Js var) and they told me that I should put it into separate template file

-.-'

What is the reason behind Git Access Tokens being viewable only once after generation on platforms like GitHub? I'm struggling to comprehend this approach as it compels me to store the key in an insecure manner.

Why are USB passkeys so expensive? I was under the impression that you 1) create a key pair, upload the public key to your google account and 2) store the private key on an old USB drive. But nooo, then you could copy the key I guess. Good luck convincing the average Joe to spend more than $10 on a fido/yubi/whatever key...

Have been searching on this topic alot lately, but I cant find any good solution, in my opinion.

I have a system where I want to encrypt some data in the database, so it isn't in plain text, but how would you do it properly?
It has to be decrypted to view the data in the system, but how to manage it?

How can I store the keys in the right way? In my current trial, I have a encryption key and an iv, but wouldn't it be wrong to store the encryption key in the config file?

Can't really see how to grasp this the right way and in the same way have it as secure as possible.
Is it just stupid in general?

I have to deal with the hardest part of programming: naming things! i fucking hate it, being so incredible uncreative finding a name for a side project..
So heres my idea: I want to build a little cli tool (and probably in the future an app or a web interface) with a rest api on my server for simple storing text snippets. I will be a simple key value store, but my goal is experimenting with new languages and software ;)
I can't imagine a cool name for that thing, do you have an idea? :)

What are the parts of the CNC Wire Bending Machine?

A CNC wire bending machine is a complex piece of equipment used to bend the wire into various shapes and configurations with precision.
