In my second year,
I told my teacher I can code in in C#(c-sharp).
She replied : C-sharp ? Oh you mean C-hash !

The moment an other team couldn't deliver for a deadline. CEO came to me, gave me 50 bucks told me to get a pizza and some hash and just work the night and deliver the damn app. So I did. Got a week holiday for free in return. One of the best guys I worked for.42

Me: how's your password security?
Them: of course we value security very highly, our passwords are all hashed before being stored.
Me: what hashing algorithm?
Them: oh we hash it with sha and then place that in a table indexed by the password.
Indexed. By. The fucking. Password.16 -
I found out recently that Facebook is embedding tracking data in the form of IPTC metadata in images that you upload. This way the images can be tracked even after you download them.
Because I'm an anarchist and just want to watch the world burn a little, I made a tiny server to replace the id hash that they embed with a random one, just to see if I can't fuck with their algorithm a little bit.
You can check out the project here https://github.com/watzon/fbmdob15 -

Project Manager: You used a hash/salt to encrypt the password in our customer database?
Me: Yes.
Project Manager: That's mean we will not be able to see the password?
Me: That's the whole point. Why would you want to see what password customer is choosing?
Project Manager: Change it. Use random encryption method.9 -

Most hated language features?
PL/SQL:
• it exists
XSLT:
• it also exists
PHP:
• it still exists.
VB:
• Significant parentheses: `subName` calls the subroutine, and `subName()` calls the subroutine and gets a return value. If you use the wrong invocation, it yells at you. Why!?
• For reasons unknown, you can only have `sleep` appear once per codebase. (So put it in a function!)
Ruby:
• It’s bloody easy to write code with absolute shit performance, and it kind of feels encouraged because of just how easy Ruby makes everything. Less critical thinking means worse performance, and Ruby’s blissful elegance encourages mental laziness.
• Minor: You cannot pass a hash as the first method parameter without enclosing it in parentheses, ex:`method({key: value})`. This is due to the ambiguous case between passing a hash argument and a (curly) block/proc (`method {|args| code}`). This could be remedied pretty easily with a little bit of look ahead.
• Minor: There is no `elsif` for `unless` (a negated if). Why? No reason given.
Python:
• no block endings, so nested code can be extremely difficult to follow.
Bash:
• The freaking syntax oh god why.
All languages:
• rand vs rand() vs Rand vs Rand() vs rnd vs RND vs random() vs random vs randInt() vs Math.random() vs Math.randInt() vs ...18 -

No, MD5 hash is not a safe way to store our users' passwords. I don't care if its been written in the past and still works. I've demonstrated how easy it is to reverse engineer and rainbow attack. I've told you your own password for the site! Now please let me fix it before someone else forces you to. We're too busy with other projects right now? Oh, ok then, I'll just be quiet and ignore our poor security. Whilst I'm busy getting on with my other work, could you figure out what we're gonna do with the tatters of our client's business (in which our company owns a stake) in the aftermath of the attack?7

worst interview was about 2 years ago. I found this job as on a famous website, I applied for a desktop dev. position...the job seemed really easy, after 10 minutes the so-called CTO asked me:" how much do you know C hash?" me:"what?" him:"C hash...the Microsoft programming language" I thanked him for his time and went home crying ( he meant c# )...after a month I found out the company had gone bankrupt...I think I know why..8

when your first try to learn a new programming language, for example c++ and you are still new to coding:
"Wtf does it behave this way. How dafuq do pointers work...argh"
and then years later, you come back to c++, do a little revision and it all starts to fall into place and make sense. Man. That feeling.3 -
I signed up for a 3 day course on c++ for revision purposes since I haven't used it in years, it was there, so why not.
So we get an email about having to install linux mint beforehand. Naturally, having ubuntu installed, i just ask if I can roll with that. And the answer is:
"Yes you just need to install the compiler, but then you won't get the credit point for the course, since you have not completed all tasks."
And an instruction was attached innthe general email on to how to create a bootable usb stick with windows and set up the partition (!) for a dualboot system for like 10 gigs of linux.
Bruh.
Da fuq.
I'm coming for the c++ not the linux. Also how do you think I've got ubuntu running in the first place? I get it the course is for beginners probably but still.
Also, after reading the instructions and knowing Windows 10 i can see bootloader issues incoming...
Was looking forward to that course now I'm not so sure. 🤔

I bought flowers for my date. Online.
When I registered, the website send me via email my 30 character long password.

So I try "forgot password". The genius website sent me, guess what, my 30 character long password...

I'm afraid these people will probably get hacked soon (murphy law).

A friend of mine bought a new laptop with an ssd and called me over since it behaved weirdly. All the icons on the desktop would turn to white squares and slowly reload their images. Also the laptop was pretty slow.
She said she had brought it to the store to show that behaviour and the only advice they would give was to reinstall windows...
So I started checking on what processes are running...
The thing was constantly running an "optimization" tool... which, you guessed it, was constantly defragmentating... the ssd... are you fkn serious who set up that shit this way... -

Remember my rant about having to write a newsletter which works with MS Outlook?
Remember that rant by @EclipseMain about teachers teaching how to build a website in MS word?
Well. The two just became united. I had finished the fking newsletter and was waiting for approval. They kept on introducing last minute changes, a commata here and there and whatnot. I literally was waiting for 2 weeks to send that shit out.
My boss gets the glorious idea that if I complain so much about Outlook and Microsoft, lets have the secretary design the newsletter from scratch, literally copying my design, in ms word... argument: one can send an html email out from word.
...
Then they ask me which one should be send out. I say I can apply the design suggestions to my newsletter but if we sent theirs, with all the weird fonts and being even less responsive then my suggestion, it would be even worse.
What the fuck.
Also: they let me waste a lot of time on this thing to tell me later oh we have money left lets hire a designer. Why not do that from the start? Ffs... <.<5 -

In ESnext, private properties are marked with `#`.
Who thought that was a good idea? No really, who thought that was a good idea?
Why not just -- I don't know -- introduce keywords like ... let me think ... public, protected and private!?
Why this:
class MyClass {
a = 1; // .a is public
#b = 2; // .#b is private
static #c = 3;// .#c is private and static
incB() {
this.#b++;
}
}
If this becomes part of the language, no JavaScript developer may joke about php usage of `$` anymore.32 -

Expert: "The core problem with passwords is that they reside on a server."
I suppose that's true, but only if you're a complete moron. Store a hash of a password, and users can authenticate against it with a password that doesn't get logged. This is technology that's been around for over fifty years. If you're storing passwords on a server, you deserve whatever trouble you get.6 -

Hmmm, this feature that I added seems to make the whole process 50% longer. I need to optimize something. Let's see now...
Yeah, make that a shared resource and parallelize IO to leverage the multi-core architecture. Hash map for this, binary tree for that. This thing that gets called a million times can be written easily without a regexp. That thing can be rewritten in Rust as it's too demanding.
There! Works! And it's also a lot cleaner. Nice!
How's the performance doing? 70% longer.

*me quering a knowledge system for a pose and quaternion*
System: here is the quaternion in w x y z format
me: but for using it I need it in x y z w
System: not my problem
me: ok, fine. here is a function that flips this, np.
*months later*
me: wtf why does grasping don't work anymore? The poses look reasonable.
*after hours of trying to debug it*
*remembers hearing someone say something about finally using one standard for quaternions across the systems*
me: wait... could this be... *comments out flip function*
me: yep... that's it.

Overall, this is an improvement. But I lost several nerves and hours yesterday night wondering why my grasping doesn't work anymore. Feeling embarrassed, that I didn't finish my stuff in time because of this bug.

My business partner who claim to be the best Wall Street programmer, probably 160 years ago, decided to improve our core system written in Go.
He dragged a *shortcut* of *whole* local github folder into Vendor(sort of node_modules), Manually changed commit hash in Gopkg.lock, etc,
Next morning I woke up to 24 failed builds on Master; all protobuf redone with his unknown gogo version, database trigger function with changed logics added parameters, and a text message “has anyone experienced build corruption? Works on my mac”
My other business partners said “it’s okay, He’s going through tough divorce needs some distraction”

Just had a talk with my manager who wanted to know why I removed a feature from an application we had. This removal had been discussed WITH THE MANAGER several months prior, but apparently they hadn't written a little note or anything down about it.
I told them we had discussed it earlier. They didn't believe me. They checked the project technical specifications that said it _should still be there_. I told them we talked about it previously. They told me to prove it, so I go looking through the commit history.
Lo and behold:
- Commit <hash> authored 4 months ago.
- Update to specifications, asked for by <manager>
Eat it.2 -

OpenSSH 8.2 is out. This release removes support for the ssh-rsa key algorithm. The better alternatives include:
1. RSA SHA-2 signature algorithms rsa-sha2-256/512. These algorithms have the advantage of using the same key type as "ssh-rsa" but use the safe SHA-2 hash algorithms (now used by default if the client and server support them).
2. The ssh-ed25519 signature algorithm.
3. ECDSA algorithms: ecdsa-sha2-nistp256/384/521.
In this release, support for FIDO/U2F hardware tokens. Also noteworthy, a future release of OpenSSH will enable UpdateHostKeys by default to allow the client to automatically migrate to better algorithms.19 -

Spent 5 hours working on a solution for a hash difficulty comparison/scaling algorithm. after a bunch of different iterations and approaches, I find that my problem can be solved by the attached equation. Its such a simple answer but no way in hell would you be able to discern the amount of time and brainpower that was put into it. The git commit is literally 10 lines of code total, but I guess its not about the amount of code, but the time spent thinking about it thay counts?

Core library was giving serious blow out of execution speed as data file size increased.
Traced it back to a GetHashCode implementation that was giving too many collisions for unequal objects, so when used as the key in a hash table it was causing the lookup to fall back to checking Equals (much slower).
Improved the GetHashCode implementation, and also precalculated it on construction (they were immutable objects), and run time went to warp speed! Was very happy with that.
Obviously put in a thread sleep to help manage expectations with the boss/clients going forwards. Can’t give those sort of gains away in one go. Sets a dangerous precedent.1 -

Install 18.04 they said. It will be fine they said...
Well.
Apperently it hates my intel graphics card. It was giving me artifacts already during installation. It didnt boot after installation and got stuck on a purple screen with the mouse on it.
Got past that with recovery mode. Googled the solution snd they said "move mouse while booting" yeah that doesn't help.
It also didn't recognize the other monitors connected to it and since it comes without unity now everything was not where I'm used to look for it.
3 hours of grub mangleing, driver installing and a unity installation later, it finally works.
Installed terminator and oh, look, one of the most used short cuts is overwritten by some emoji pick bs.

Multi-Screen problem: So I need to run a VR headset with a laptop, and the laptop has only one hdmi connection. I don't have any extra hdmi adapters, so I cannot connect my second screen while working with the headset, which sucks...
but...
then it hit me...
there is an app called spacedesk which allows you to use your phone as an additional screen. I have a docking station for my phone so I can connect hmdi to it. On the first try the resolution was shit since it uses the default phone resolution. But the phone has Samsung Dex, which allows you to run everything full screen on your connected screen, so I can run the app within Samsung Dex and therefore will get full resolution.
And this works. It's kinda stupid and maybe a bit complicated, but it works. God, I love technology :D:D:D

Whenever I have to ask about how certain code of someone else works, I feel bad. I feel like I should be able to figure it out on my own.
On the other hand, if people ask me to implement something within their code, that I am not familiar with, I kinda expect more info? Like if you don't have any tutorials or documentation on your tool, be prepared to answer some stupid questions about how to set it up and whatnot. How else am I gonna know how to start with? Having to read the entire source code is a massive waste of time, no?
tl;dr: if you don't provide documentation or tutorials, be ready to answer stupid questions.8 -

when you have to use one language inside of another, and you basically have to call functions allowing you to call the other's language function within it, and you get the hell confused, since it gets harder and harder to see what is what and who can call who and how, and the compiler ofc. won't say anything about it since it only cares about the main language you are in and not the nesting of the other...
I just have no idea what I'm doing right now, or if my thought process and understanding of this is even close to where it is supposed to be.

I've finally got a monitor at work that works with Samsung Dex.
Positive things:
- new super cool monitor
- can remove windows now from the dual boot of the laptop since everything I needed it for can be now done on Dex.
Negative things:

Unreal Engine fun continues...
so I need to set limits to rotations within a skeletal mesh. So in other programms, like blender, you can specify a limit per axis, setting max and min angle. Makes sense, right?
Unreal Engine:
1. Let's call rotations sometimes xyz, sometimes roll pitch yaw, and sometimes swing1 swing2 and twist so that nobody knows what it is anymore.
2. IK node 1: limits? what are limits?
3. IK node 2: ok, you can set angular limits but they are all symmetrical to god knows what and to all axis apperently.
4. Physics: yeah you can define joint constraints but we give you only symmetrical constraints also
....
WHY. Were does this make any sense? One node is not like the other, and they talk rotations but use 100 different terms for them, since, hey, why the f not. And let's limit everything symmetricly so you can only set one value or have to fiddle with offsets to achive the range of movement you want.

I was just on my way to work back from the University cafeteria when a guy in a black car - who I thought was moving the car out of a parking lot - stopped the car and asked if I had a second.
Naive me, thinking he might need directions or something decided to listen to him.
He looked older, around 60ish, with sunglasses on ( making it harder for me to read him).
He said that he had a stroke (or something) a few years ago and got damage to his brain, so that sometimes it can happen that he would faint. Therefore, he cannot go swimming unsupervised, and was asking if I would have the time to accompany him to the university lake, so that he could swim for an hour or so. He offered to pay me 40 bucks.
Me, being paranoid af, declined politely, saying I have to go to work ( which was actually true).
He goes on to say how he was a teacher, how he worked at the university before, how I look trustworthy, how I am the first person he asks today, and asked if he could have my number, so that he could call me sometime to supervise the swimming. I would just need to look out for him not to drown and if anything looks weird I should alarm the people working at the lake ( lookouts? not sure what they are called).
I kept declining politely and he backed off, letting me go without any fuzz.
Previously he also mentioned how some students are rich, others are poor, and how he would have done anything for 20 bucks back in the day. But also said that he accepts a no and won't bother me further.
He also mentioned he wouldn't lay a hand on me, that he is not a creep, since I could see his car and license plate, and if I gave him my number, I would also have his. That I shouldn't worry about anything, if I later decided to say no he would delete my number, and that he is not big on the technology and Internet so nothing would happen.
Uhh... well if he was genuine I'm sorry for him, but then you can just ask authorities at the beach to pay more attention to you, no?
Mentioning "all my worries" raised a red flag for me sort of.
Also, if you keep on fainting occasionally, even if you haven't fainted in 2 years, how are you allowed to drive? Or actually, why do you even drive then?
I don't know. The more I think about it, the more I think I should have taken a picture of the car or license plate.
And there are literal services for this kind of thing. Pretty sure you can get one of these if you are willing to pay even.
Jeez now I'm worried for the entire population of my university...9 -

What container data structures do all of you actually use?
For me, I'd say: dynamically sized array, hashtable, and hash set. (And string if you count that.)
In the past 8 months, I've used another container type maybe once?
Meanwhile, I remember in school, we had all these classes on all these fancy data structures, I havent seen most of them since.19 -
This semester, we have a lecture called IT Security by a guy, who absolutely know his subject.
Nevertheless, he wanted to show us that sha256 is broken by an existing collision. (Google that, fellow ranters!)
There are two pdf files by google researchers, that show the caption „SHAttered“ both on different backgrounds, although they give the same SHA-hash.
He then tried to share us these two files by moodle and wondered, why he uploaded the same file twice.
Guess what happened? The moodle backend checks new uploaded files for their ... hash ... and then decides, weather to upload or the file is already existing. So, it did just a new symlink to the old file.
Ironic, that an exercise, that should show us sha collision failures on sha collision 😃5 -
Unreal Engine + third party library adventures part2:

The Dependencies are broken and incomplete as always and the tutorial is not up to date. Big suprise. I get it, it's a lot of work to keep these things up to date. But please if they are this broken and incomplete why are they released in the first place.

Unreal engine adventures part 3:
Code compiles. Everything is fine. Close engine and open it up again since I'm coding a anim graph node and it does not update it unless you restart it.
Unreal crashes...

I discovered a commit message from one of my (senior) colleagues today. It made me shudder. It read, 'Just adding some changes made outside of source control and deployed (over last 12 months)'.

VirusTotal's API could do with a make over.
Though it is quite nice actually, you're able to provide them with a hash of a file and (provided they've scanned it) VT is able to tell you what up to 60 different virus scanners thinks about the file (and how many scanners that has an opinion about it). Now if there's an error, like the file not having been scanned or the hash being incomplete, it give you some JSON back where there will be an error message that tells you the error and an error code of 0.. wait wh
Although since it's an API they also need give us plebs whose only got access to an API key that limits us to 4 requests pr minutes. Naturally when you try to do another request within a minute of your limit the response you get is absolutely nothing what so ever. "" Naturally.
And of course the same response should be given when the API key you provide isn't valid. Who needs errors amiright?
No wonder JSON.parse kept throwing exceptions

I forgot my password to my mindfactory account, one of Germany's biggest online vendor for computer components. So I go through the resetting process, which is:
- apply for password reset
- get a mail
- confirm the mail
(So far, so good)
- get a mail with a new CLEAR TEXT PASSWORD
Is this the stone age!?
You never send an email containing the cleartext! You never even store the password as is!
You, as the provider, should never be able to know what the actual password was.
All you are supposed to do is to generate a random salt, and hash the user's password with the salt, and then you only store the salt and the hash. And whenever a user inputs their password, all you do is to check if the you can recreate the hash with the help of the salt and your hash algorithm. (There are libraries for that!)
If a user wants to reset their password? Send them to a mail with link on where they can assign a new password.
At no point should the password ever be stored or transmitted in any other medium.5 -

If I were to change all my passwords into hashes (so take a random word and hash it, ex 'table') and then use those on various websites, would people ever guess that my password is _an actual hash_ rather than a password in hashed form if they were to see it?

So, I need to search for a new job again. The thing killed my project.
15 years of Java experience in my resume, I look a like a sterotypical 35 years old programmer, I’m applying for expert roles. But every remote technical interview starts with:
- what is the difference between ArrayList and LinkedList?
- what is a hash map?
The hardest part is to keep smiling to the camera, pretending I don’t have the answer memorized by repeating it for the last 15 years of interviewing, and not rolling my eyes.
And before you ask, I do know what garbage collector is.5 -
whenever I think I am almost done with coding something, and go like "yeah, I can totally finish this the next day within just a few hours. Just add 1-2 functions and done" - it ends up being the opposite. I either realize how many things I didn't think and implement through and end up adding lots of things or I come up with a different approach to things which seems better and have to rework half my stuff...
I guess this will get fixed with experience.
Until then, I guess I'll keep trolling myself. -
I had joined a new company and got access to their codebase. They were updating password on MD5 hash of user name and their email in get request. No password validation, no token based authentication, nothing.

That's it, you get change user password. -
I took Database System Class and Courses in University, and told to store the password using its hash and don't store it in plain text; it is at least a standard.
today i just resetting my gmail password since i forgot the password. and i wonder by how google forgot password mechanism work.
for example i register the password with:
'xxxfalconxxx'
and then change it to:
'youarebaboon123'
sometimes later i forgot both password, and google asked for the last password i remember; and i only remember part of it so i entered:
'falcon'
and this is right, so i can continue the forgot password mechanism. how could you check the hashed text of 'falcon' is the subset of hash text 'xxxfalconxxx' ?2 -
I'm going through a KhanAcademy course learning about cryptography. I learn better by doing, so I wrote a script.

Ended up with 16.04 and 18.04 ubuntu in dual boot. (see last rant).
Fixed graphics issues on 18.04. The fix envolved setting stuff in grub. Ok.
Now we apparently need 16.04 again and can kich the 18.04.
np. Let me just boot my 16.04
oh look who has graphics issues now!
It boiled down to the grub settings. so Depending on if I need 18.04 or 16.04 I need to fiddle with grub. great.
And now we don't neet 18.04 at all. So I tried to do something not in the last minute once, and it backfired completly. Wasted 5h on this shit this week. Fk this.2 -
when you think you're done coding and can finally start writing...
So you guys have seen my Unreal Engine adventures. I have to use a plugin for it, on top of everything, to extract some data. I've been using this plugin since ages on another pc, but now I had to set it up from scratch since this is a new project, new models, etc.
There is a new version. If I use the new one, it will break the chain which is to follow.
The old version is so legacy that the guy who wrote it does not remember how to set it up.
After hours, and tons of hacks and outcommenting stuff (there is physics involved with which I do nothing), it finally starts doing something. Finally!
Although I'm slowly loosing my sanity in the process....
Even if it now records the data, I cannot say if this is good enough or if the poses are all wonky now.
And that is my masters thesis. Submission deadline is on monday. Ha.
Ironically, since the start of this thesis, I felt like this will either make me or break me. ;D So much fun... FK2 -

Just found the most embarrassing security hole. Basically a skelleton key to millions of user data. Names, email addresses, zip codes, orders. If the email indicates a birthdate, even more shit if you chain another vector. Basically an order id / hash pair that should allow users to enter data AND SHOULD ONLY AUTHORIZE THEM TO THE SITE FOR ENTRING DATA. Well, what happend was that a non mathing hash/id pair will not provide an aith token bit it will create a session linked to that order.
Long story short, call url 1 enter the foreign ID, get an error, access order overview site, profit. Obviously a big fucking problem and I still had to run directly to our CEO to get it prioritized because product management thought a style update would be more important.
Oh, and of course the IDs are counted upwards. Making them random would be too unfair towards the poor black hats out there.1 -
Fun fact: If you ever want to see the password you are typing or view the contents of a password field in a form, just pull up the web inspector. You can change the input type from "password" to "text" with no ill effects upon submission.
The lesson? When populating password fields, put junk values in there instead. Will present the right appearance, and doesn't risk exposing something that should be stored as a salted hash anyway.3 -

So Igot that Samsung DeX thing a while ago. So far, it was just a nice gadget to have at hand, but I didn't get to use it properly since my laptop was always the better option sort of.
Now.
My power adapter for the laptop died last friday. I have a second one at home, but of course, I pack the wrong one for work.
Ended up working the entire day on the DeX. Thankfully, I just needed to do some web and office based stuff, and all the necessary documents are online anyway.
So that thing just saved my butt today, which is nice. Took a while to get used to, but it does it's job quite nicely.
To be honest: Iam suprised it works the way it does. Oh what a time to be alive...

I am trying to "invent" secure client-side authentication where all data are stored in browser encrypted and only accessible with the correct password. My question is, what is your opinion about my idea. If you think it is not secure or there is possible backdoor, let me know.
// INPUT:
- test string (hidden, random, random length)
- password
- password again
// THEN:
- hash test string with sha-512
- encrypt test string with password
- save hash of test string
// AUTH:
- decrypt test string
- hash decrypted string with sha-512
- compare hashes
- create password hash sha-512 (and delete password from memory, so you cannot get it somehow - possible hole here because hash is reversible with brute force)
// DATA PROCESSING
- encrypt/decrypt with password hash as secret (AES-256)
Thanks!
EDIT: Maybe some salt for test string would be nice8 -

So our project decided to create a newsletter. For some reason, I was tasked with writing it, includig layout, recepient database etc.
It is the first newsletter, it is urgent and it is supposed to be send to all the people who so far participated. Means: there was never a "sign up here for a newsletter" thingy on the website. Hence, there is also no "unsubscribe" button.
One could kind of "hotfix" this by making a field, like "enter your email adress here to unsubscribe" and then I get a notification and remove the people from the list. Fine by me. Not so many ppl atm so we got time to set it up properly then.
My boss decides it is my job now to implement the stupid unsubscribe button... I am not the website admin. I have nothing to do with the goddamn website. We have ppl in another city, being paid to manage the goddamn website and it would take them just a few minutes to set the stupid button up, since they know what they are doing and I am not.
I told them from the start: I don't do websites. I have nothing to do with them, I don't want to have anything to do with them. We have people for this.
Why the F is it my job now to implement that stupid button?!
And even when I tried to look into how the other formulas which do similar things are set up: oh you don't have permissions to access that. Lovely!

Not a rant but I kinda wanted to see if anyone else feels the same way and might have advice on how to overcome this:
So I work as a student in research. Meaning there is not much documentation and things are chaneging fast, some things are also fairly complicated.
I have a really good supervisor.
However. I am super scared of asking about how things work. Whenever we discuss things and she notices I'm insecure about how something works, she explains it to me patiently. No probs. But insead of asking I just try out random stuff for hours. Having no clue about how things work and what I'm doing. In the end she is able to explain the issue to me within a minute.
The thing is, I think that trying to figure stuff out on my own, is the right approach. Not daring to ask questions or express my theories is really bad. I get super anxcious. Most of the time my theories and assumptions are correct. I just never dare to voice them.
The irony is, that I'm perfectly fine whenever I talk about or hold presentations which are not CS related. But if I have to do that on a CS topic I just die. I freezze, stutter, everything.... T_T
Like come on. They can't do anything to me except correct me... jeez.2 -

You know how people want to avoid collisions with a hash map?? Well a buddy and I went to a hackathon about 2 years ago, and the idea we had was kinda cool, but to get a prototype working, we decided to defy the logic of a hash table and purposefully cause collisions with a hash map. I took a look at the project and it is soooo poorly implemented.

I've seen a lot of buzz around the EU's GDPR and since I don't live there I'm wondering if it applies only if you store personal data and should it count if it's hashed for example?🤔
Let's say you hash a client's IP, it's not technically his data you've irreversibly transformed it into something else, like a computation.
For example let's say he provides you with a number and you multiply it by another and store the result, let's say 2 x 2 = 4, Is the 4 his data or yours?

Now this cheap genius wants to be able to login as a seller and manipulate whatever products they've listed. So I told the client it's not possible to do that because passwords are stored as hashes. Now, can you Guess who's storing clear text passwords ?

Am I the only one who when studying for an exam has the urge to copy all the slides by hand? And I mean not typing, good old handwriting. Then scrible in them and add own notes, write a summary and then try to recall it all.
It doesn't seem very efficient but I do not feel complete or even remotely prepared if I haven't done this. Although I did pass exams in the past without doing all of this...2 -

My mum signed me up for a robotics workshop with Lego mindstorms... i kept going to these workshops, doing some of them multiple times. At some point we went from graphical programming to some other kids language, than we made a robocup junior team from the kids who were like me and kept on showing up at these workshops and used arduino and C. Had a break for a year or so from coding so I could finish school, then I went studying computer science at Uni. And the rest is history.

- cross-platform IMA/VFD/VHD/VHDX/qcow/VMDK/IMG/DSK/others image read/extract support that doesn't need admin/root privs (so no, can't use dd or mount)
- custom DB format (for speedups when indexing files and retrieving info based on hash) and converter from previous DB format
- GUI or actually good CLI
- massive speedups

So I start up the Windows Upgrade Assistant to upgrade my Windows 10 to the anniversary edition and it shows me that I'm running version 10240 and I can upgrade to the latest version 14xxx.
So I hit upgrade now, wait for 10 minutes for the update to be downloaded and another 10 minutes for the update to be installed. Then it does the customary reboot after update.
So now I assume that I'm running the anniversary edition of Windows 10 but it shows that I'm still running 10240.
WTF was the upgrade assistant doing in those 20 odd minutes. And now it does it in an infinite loop. Is Microsoft trying to explain me what an Infinite loop looks like practically.2 -
On page 19 of the ethereum yellow paper: http://gavwood.com/paper.pdf it defines the address of a wallet as: A(pr) = Β[96...255](KEC(ECDSAPUBKEY(Pr))), which is the right most 160-bits of the Keccak hash of the public key generated by the private key.
If I expose the public key to the network, do I allow people to impersonate me and sign transactions even though they don't have Tr, Ts, or Tw? My understanding is no, that without those values you can't hash the transaction.
Subsequently, this leads me to wonder if the purpose of the address (besides identifying users) to obscure the public key so that the private key is at a less risk of being reversed? Or can the public key of any address be captured?
If the public key of any address can be identified on the network or off network (without actually being the owner of that key), how do you do that? Are there any resources on how to perform this that are computationally easy?1 -

Crypto. I've seen some horrible RC4 thrown around and heard of 3DES also being used, but luckily didn't lay my eyes upon it.
Now to my current crypto adventure.
Rule no.1: Never roll your own crypto.
They said.
So let's encrypt a file for upload. OK, there doesn't seem to be a clear standard, but ya'know combine asymmetric cipher to crypt the key with a symmetric. Should be easy. Take RSA and whatnot from some libraries. But let's obfuscate it a bit so nobody can reuse it. - Until today I thought the crypto was alright, but then there was something off. On two layers there were added hashes, timestamps or length fields, which enlarges the data to encrypt. Now it doesn't add up any more: Through padding and hash verification RSA from OpenSSL throws an error, because the data is too long (about 240 bytes possible, but 264 pumped in). Probably the lib used just didn't notify, silently truncating stuff or resorting to other means. Still investigation needed. - but apart from that: why the fuck add own hash verification, with weak non-cryptographic hashes(!) if the chosen RSA variant already has that with SHA-256. Why this sick generation of key material with some md5 artistic stunts - is there no cryptographically safe random source on Windows? Why directly pump some structs (with no padding and magic numbers) into the file? Just so it's a bit more fucked up?
Thanks, that worked.3 -
I have several tasks in my job. Not all of them are straight up dev, some are also student related. Since my coworker left I was rediculously overbudened, simply because the tasks I have to do are sooo far appart from one anothet. After talking to my boss, we get to hire some people to help (big yay!) But now it is upon me to write the recruitment adds so to speak and also talk to the people and interview them.

So, we're preforming a re-write an application. It's on an application (actual mortgage application, not 'app') that has 4 different entry points. We have the most common entry point converted to our re-written application with plans to have the next couple done over the next several weeks. Yesterday, the old version broke. It was under the impression that it could grab any row that matched the borrower and then check against a hash of that data to see if it could proceed. It can't. You can't hash data set 1 and expect it to be the same as the hash for data set 2. Not a thing. When asked, the only answer we could give right away was "We'll fix it, give us a couple of minutes" and "Sorry, bad {{appName}} is bad. We don't know root cause yet. We'll let you know when we do." Was pulled aside by my manager and told my answer was unsatisfactory and I shouldn't give answers like that. I get it, "Bad {{appName}} is bad" isn't great, but it's not like we were going to give that and leave it! We needed some time!2

anyone else having a few hours of not being able to focus after lunch? Or is that just me?
It doesn't matter what I eat or what I do, after lunch I just can't focus on anything. Until 4-5 pm. then focus comes back again.
The only solution to this that I have is basically don't eat a full meal at lunch, but try to have healthy snacks instead.
I dunno.

I think today might be the day I'll bring ubuntu onto my big laptop. It had only windows for many years now and I did all my dev work on my smaller laptop that I carry around with me.

Fuck you Linux! I thought user password validation would be a piece of cake, like bash one liner. How wrong could I be!
Yeah, it's already ugly to grep hash and salt from /etc/shadow, but I could accept that. But then give me a friggin' tool to generate the hash. And of course the distro I chose has the wrong makepswd, OpenSSL is too old to have the new SHA-512 built in, as it should be a minimal installation I don't want to use perl or python...
And the stupid crypto function that would do me the job is even included in glibc. So it's only one line of C-code to give me all I want, but there is no package that would provide me this dull binary? Instead I will have to compile it myself and then again remove the compiler to keep image small?5 -
So I'm working on an assignment for my Computer Science class, and we have to basically compute strings into hash values and then modulo it by 1 million and put it into the hash table. But the value keeps overflowing and turning into negative values, anyone know how I can calculate the key?

Reading the source of a message queue system I'm planning on extending.
I don't see myself as a rockstar programmer or anything but the construction of arrays from hash tables, sorting those arrays and then a nested for loop to find matches really irks me. Luckily not on the critical message processing path but the stats collection thread. There are mutexes in play though that would probably delay processing a little bit when stats are collected. -

I wanted to know what is the worst mistake you make on database.
I have actually implements the logic of token access control on database and not on business logic layer.
The database have a login procedure which accept username and password. That login procedure actually hash the password and try to authenticate user.
If it is a correct user , it generate a token. In other to use other procedure on database , you must provide a token. By using that token , the procedure know who is it and what permission is granted to that user.4 -
My last promotion was/is my first Software Development job and a significant increase in pay.
I worked for this company for 12 years, quit for 2.5 years, got a job in a different industry in the mean time, and taught myself to write some code.
Due to some personal changes, I ended up coming back to this company.
After being in the engineering team for a year I applied for the corporate software dev gig. They liked I had floor experience and took initiative to teach myself.
I would consider myself entry level and it shows on my resume, so I was surprised they took a chance on me. The boss says I'm doing a great job, so that feels pretty good!1 -

Been wondering about something and can't figure out if I am a retard or a genius 😂.
If MD5 is so outdated and should not be used to store password hashes (let's say for whatever reason you cannot effectively switch to another algorithm) wouldn't it just be easier and more secure to just re-encrypt the hash again, so just MD5 the MD5 hash... in theory, wouldn't that make the hash virtually uncrackable because instead of trying to brute force actual real words, you now have a hash of essentially random characters which have no relation to the others, and even then, suppose you manage to crack the hash, you will get another hash to crack before getting to the password?5 -
Anyone learn about Bloom filters in school? I was watching a lecture and he mentioned using a Bloom filter with a few hash functions to create a cache you can use to avoid querying a table if there's no match, which is a neat idea.

I really cannot see why there still isn't an API in Java where I can get an hashing algorithm without having to catch a checked exception.
Granted, Bouncy castle is a top library. But of you just have a small application with a single method wanting to hash a few values... It's so nuts and unnecessary.
So what do you do in the catch block? Either throw a checked exception (because without that hash your app won't work), or calculate a replacement. But if it were that easy, I wouldn't have needed a hash on the first place.
I really wonder what the java developers had in mind.
Same with IO exception. I'm beginning to like python more and more.

My first year of a 2 year course our teacher had only taught us 2 theory topics of 6 and hadn't begun to teach us the other 2/3 of the course which was programming. The only reason he took so long was because he wanted everyone to understand the topic before he moved on which meant waiting for the people who shouldn't of been allowed to take the subject because they never paid attention and showed no interest in the subject. But he refused to move on without them.
To drag those 2 topics out more one of them was algorithms. At the time he had sprained his wrist shadow boxing and instead of preparing them before hand to give us some help he would type them out while we sat and watched wasting half the lesson. Then a month or so into our second year he left leaving the other teachers to make up for everything he failed to cover with us. -

I was hovering through some leetcode problems when I came across a hard question that is forcing me to use a hashmap with the key of the user-defined type. I made up my mind to make use of C++ for the coding interview. Now, the problem is C++ asks me to implement a hash function.
If in case, I'm asked a similar question like this in the interview, which of these two options will you suggest:
a) implement your own hash function
b) use pointers as key2 -
