tl;dr: Windows' MAX_PATH is the devil, and it basically does not allow you to copy files with paths that exceed this length. No matter what. Even with official fixes and workarounds.
Long story:
So, I haven't had actual gainful employ in quite awhile. I've been earning just enough to get behind on bills and go without all but basic groceries. Because of this, our electronics have been ... in need of upgrading for quite awhile. In particular, we've needed new drives. (We've been down a server for two years now because its drive died!)
Anyway, I originally bought my external drive just for backup, but due to the above, I eventually began using it for everyday things. including Steam. over USB. Terrible, right? So, I decided to mount it as an internal drive to lower the read/write times. Finding SATA cables was difficult, the motherboard's SATA plugs are in a terrible spot, and my tiny case (and 2yo) made everything soo much worse. It was a miserable experience, but I finally got it installed.
However! It turns out the Seagate external drives use some custom drive header, or custom driver to access the drive, so Windows couldn't read the bare drive. ffs. So, I took it out again (joy) and put it back in the enclosure, and began copying the files off.
The drive I'm copying it to is smaller, so I enabled compression to allow storing a bit more of the data, and excluded a couple of directories so I could copy those elsewhere. I (barely) managed to fit everything with some pretty tight shuffling.
but. that external drive is connected via USB, remember? and for some reason, even over USB3, I was only getting ~20mb/s transfer rate, so the process took 20some hours! In the interim, I worked on some projects, watched netflix, etc., then locked my computer, and went to bed. (I also made sure to turn my monitors and keyboard light off so it wouldn't be enticing to my 2yo.) Cue dramatic music ~
Come morning, I go to check on the progress... and find that the computer is off! What the hell! I turn it on and check the logs... and found that it lost power around 9:16am. aslkjdfhaslkjashdasfjhasd. My 2yo had apparently been playing with the power strip and its enticing glowing red on/off switch. So. It didn't finish copying.
aslkjdfhaslkjashdasfjhasd x2
Anyway, finding the missing files was easy, but what about any that didn't finish? Filesizes don't match, so writing a script to check doesn't work. and using a visual utility like windirstat won't work either because of the excluded folders. Friggin' hell.
Also -- and rather the point of this rant:
It turns out that some of the files (70 in total, as I eventually found out) have paths exceeding Windows' MAX_PATH length (260 chars). So I couldn't copy those.
After some research, I learned that there's a Microsoft hotfix that patches this specific issue! for my specific version! woo! It's like. totally perfect. So, I installed that, restarted as per its wishes... tried again (via both drag and `copy`)... and Lo! It did not work.
After installing the hotfix. to fix this specific issue. on my specific os. the issue remained. gg Microsoft?
Further research.
I then learned (well, learned more about) the unicode path prefix `\\?\`, which bypasses Windows kernel's path parsing, and passes the path directly to ntfslib, thereby indirectly allowing ~32k path lengths. I tried this with the native `copy` command; no luck. I tried this with `robocopy` and cygwin's `cp`; they likewise failed. I tried it with cygwin's `rsync`, but it sees `\\?\` as denoting a remote path, and therefore fails.
However, `dir \\?\C:\` works just fine?
So, apparently, Microsoft's own workaround for long pathnames doesn't work with its own utilities. unless the paths are shorter than MAX_PATH? gg Microsoft.
At this point, I was sorely tempted to write my own copy utility that calls the internal Windows APIs that support unicode paths. but as I lack a C compiler, and haven't coded in C in like 15 years, I figured I'd try a few last desperate ideas first.
For the hell of it, I tried making an archive of the offending files with winRAR. Unsurprisingly, it failed to access the files.
... and for completeness's sake -- mostly to say I tried it -- I did the same with 7zip. I took one of the offending files and made a 7z archive of it in the destination folder -- and, much to my surprise, it worked perfectly! I could even extract the file! Hell, I could even work with paths >340 characters!
So... I'm going through all of the 70 missing files and copying them. with 7zip. because it's the only bloody thing that works. ffs
Third-party utilities work better than Microsoft's official fixes. gg.
...
On a related note, I totally feel like that person from http://xkcd.com/763 right now ;;21 -
I'm sick of how much abuse PHP gets from other programming communities. PHP written well, using PHP 7 is comparatively quick. yes it has its quirks, just like JavaScript, but just because you can do stuff in multiple ways, and the language has a few inconsistencies doesn't make it a bad language. The recursive flag in bash applications changes case inconsistently (I.e. zip and cp) but that doesn't get bashed (lol) half as much....
I think I need to finish my coffee this morning29 -
Every. Commit. My Boss. Makes. Is 'cp'. I come in this morning to find 1882 insertions, 143 deletions to master, and this is the commit log for the entire weekend.
How. In the fuck. Am I supposed to effectively work on this project. If I can't keep up with changes.10 -
I got arrested multiple times under acts of cyber crimes...
Yeah, so what if I did? Why is it a problem that I take down CP sites? "Because it's partaking in cyber warfare." Well then the police and the Federal government should execute their job keeping such out of the web space. Now, whenever I find a job, I have to inform due to the judge's final document. And not just that now when I am required to talk to a police officer who has seen my record all they can reckon is to escalate it.
What fantastic horse crap! You get arrested for tracking down child molesters and taking them off the web exclusively...
Some say I'm a social justice warrior, only I don't think that I am. I reckon I am merely an over eccentric programmer who desires to see the real criminals get sent to jail.30 -
Me: Why dosn't cp return an error code when the file in the first argument doesn't exist?
Coworker: Well, you copied a file that doesn't exist to a destination that also doesn't exist, sounds like a successful copy to me.1 -

It took forever to get SSH access to our office network computers from outside. Me and other coworkers were often told to "just use teamviewer", but we finally managed to get our way.
But bloody incompetents! There is a machine with SSH listening on port 22, user & root login enabled via password on the personal office computer.
"I CBA to setup a private key. It's useless anyways, who's ever gonna hack this computer? Don't be paranoid, a password is enough!"

Just now I realized that for some reason I can't mount SMB shares to E: and H: anymore.. why, you might ask? I have no idea. And troubleshooting Windows.. oh boy, if only it was as simple as it is on Linux!!
So, bimonthly reinstall I guess? Because long live good quality software that lasts. In a post-meritocracy age, I guess that software quality is a thing of the past. At least there's an option to reset now, so that I don't have to keep a USB stick around to store an installation image for this crap.
And yes Windows fanbois, I fucking know that you don't have this issue and that therefore it doesn't exist as far as you're concerned. Obviously it's user error and crappy hardware, like it always is.
And yes Linux fanbois, I know that I should install Linux on it. If it's that important to you, go ahead and install it! I'll give you network access to the machine and you can do whatever you want to make it run Linux. But you can take my word on this - I've tried everything I could (including every other distro, custom kernels, customized installer images, ..), and it doesn't want to boot any Linux distribution, no matter what. And no I'm not disposing of or selling this machine either.
Bottom line I guess is this: the OS is made for a user that's just got a C: drive, doesn't rely on stuff on network drives, has one display rather than 2 (proper HDMI monitor recognition? What's that?), and God forbid that they have more than 26 drives. I mean sure in the age of DOS and its predecessor CP/M, sure nobody would use more than 26 drives. Network shares weren't even a thing back then. And yes it's possible to do volume mounts, but it's unwieldy. So one monitor, 1 or 2 local drives, and let's make them just use Facebook a little bit and have them power off the machine every time they're done using it. Because keeping the machine stable for more than a few days? Why on Earth would you possibly want to do that?!!
Microsoft Windows. The OS built for average users but God forbid you depart from the standard road of average user usage. Do anything advanced, either you can't do it at all, you can do it but it's extremely unintuitive and good luck finding manuals for it, or you can do it but Windows will behave weirdly. Because why not!!!12 -
Just in case nobody has mentioned this yet:
Yes Microsoft I do have a dualhead setup.
Yes Microsoft I do want to watch video on my left screen while having window focus on something on the right monitor.
No Microsoft this doesn't mean that I *lost* focus on the left window.
No Microsoft this doesn't mean that I want your Movies and TV application to suddenly minimize (and continue playing anyway) while I focus on some server monitoring window on my right display.
Microsoft, there exist people that use more than your average user with a single C: drive that play Candy Crush on Facebook all day. And the limitations that you currently impose might very well be what keeps the Microsoft UWP applications from getting adopted. Because you know what? SMPlayer, a default application in any of my Linux workstation machines, it does handle such window transitions just fine!
Microsoft, I love how you at least gave us the option to enable Ctrl-Shift-C and Ctrl-Shift-V in WSL and conhost in general over that abomination that is Right-click and Return (those are so random!) that are relics from CP/M. But seriously? At this rate, I'd definitely not call it usable for anyone but those with a single monitor yet.
So please _/\_13 -
After months of studying dynamic programming, I can finally say with confidence that I UNDERSTAND NOTHING.7

Personal project: I design and build single-board computers with old processors like Z80, 6502 etc when I'm not being too lazy. A few run CP/M. One that's been more interesting in terms of digging deeper has been an 80C188, for which I've written a BIOS (despite the chip's built-in peripherals and interrupts being at non-standard addresses) mostly in C, which it can use to boot DOS from an image file on an SD card (bit-banged off the UART chip with FatFs). (Yes it's slow, but so is a 5.25" floppy.)
Work: My first project at my current job. Not particularly exciting compared to some stuff on here, but it got me into making useful contributions to the open-source CRM we used at the time. Was building a basic extension to deal with duplicated organisation names. So learned CiviCRM fairly deeply, a bit of Drupal, a bit of PHP. It's a shame we don't use that system any more, the community was cool.7 -
I really despise solving competitive programming problems.
I truly believe it's okay to struggle with them and that people have different abilities. But these kind of problems are an easy way to make you hate yourself and think of yourself less.
I can't solve this problem --> I'm not a good programmer --> I'm not smart enough --> I'm not good enough like my peers who work at FA*G companies, ...
I know these interview problems are a filter and that recruiting is hard and the demand is always high and that they are nothing like the real work but, the reality is, you need to prepare if you want to get into one of the big companies with better perks and maybe better projects.3 -
This is a story of how I did a hard thing in bash:
I need to extract all files with extension .nco from a disk. I don't want to use the GUI (which only works on windows). And I don't want to install any new programs. NCO files are basically like zip files.
Problem 1: The file headers (or something) is broken and 7zip (7z) can only extract it if has .zip extension
Problem 2: find command gives me relative to the disk path and starts with . (a dot)
Solution: Use sed to delete dot. Use sed to convert to full path. Save to file. Load lines from file and for each one, cp to ~/Desktop/file.zip then && 7z e ~/Desktop/file.zip -oOutputDir (Extract file to OutputDir).
Problem 3: Most filenames contain a whitespace. cp doesn't work when given the path wrapped in quotes.
Patch: Use bash parameter substitution to change whitespace to \whitespace.
(Note: I found it easier to apply sed one after another than to put it all in one command)
Why the fuck would anyone compress 345 images into their own archive used by an uncommon windows-only paid back-up tool?
Little me (12 years old) knowing nothing about compression or backup or common software decided to use the already installed shitty program.
This is a big deal for me because it's really the first time I string so many cool commands to achieve desired results in bash (been using Ubuntu for half a year now). Funny thing is the images uncompressed are 4.7GB and the raw files are about 1.4GB so I would have been better off not doing anything at all.
Full command:
find -type f -name "*.nco" |
sed 's/\(^./\)/\1/' |
sed 's/.*/\/media\/mitiko\/2011-2014_1&/' > unescaped-paths.txt
cat unescaped-paths.txt | while read line; do echo "${line// /\\ }" >> escaped-paths.txt; done
rm unescaped-paths.txt
cat escaped-paths.txt | while read line; do (echo "$line" | grep -Eq .*[^db].nco) && echo "$line" >> paths.txt; done
rm escaped-paths.txt
cat paths.txt | while read line; do cp $line ~/Desktop/file.zip && 7z e ~/Desktop/file.zip -oImages >/dev/null; done3 -
Replaced a colleague's busted HDD and gave him the old one to copy over stuff.
When I came back, the guy was about to copy over the root folder of the old one over the new one .... And I mean 'drag and drop' not even 'cp -r' -
Today I learned:
In Java, you're supposed to compile a source file in its package one directory up, outside of its package. You can't compile the source file in its own package directory, for it will state "cannot find symbol" on files in the same package, even though they're in the correct package directory. That can be quite confusing at first.
Given the following directory structure:
|_
|_ \pkg
|_ _ Src1.java
|_ _ Src2.java (interface with static method)
and the following source:
package pkg;
public interface Src2 { static void doStuff() { ... }; } // assuming JDK8+, where static default methods are allowed
package pkg;
public class Src1 { public static void main(String[] args) { Src2.doStuff(); } }
..being inside the pkg/ directory in the console,
this won't work:
javac -cp . Src1.java
"cannot find symbol: Src2"
However, go one directory up and..
javac -cp pkg/*.java pkg/Src1.java
..it works!
Yeah, you truly start learning how the compiler works when you don't use the luxury of a IDE but rather a raw text editor and a console.1 -

How do you define a seniority in a corporate is beyond me.
This guy is supposed to be Tier3, literally "advanced technical support". Taking care of network boxes, which are more or less linux servers. The most knowledgable person on the topic, when Tier1 screws something and it's not BAU/Tier2 can't fix it.
In the past hour he:
- attempted to 'cd' to a file and wondered why he got an error
- has no idea how to spell 'md5sum'
- syntax for 'cp' command had to be spelled out to him letter by letter
- has only vague idea how SSH key setup works (can do it only if sombody prepares him the commands)
- was confused how to 'grep' a string from a logfile
This is not something new and fancy he had no time to learn yet. These things are the same past 20-30 years. I used to feel sorry for US guys getting fired due to their work being outsourced to us but that is no longer the case. Our average IT college drop-out could handle maintenance better than some of these people.11 -
So an update on my last health rant..
It's got off to a great start... not
My intentions were to go into NYC to walk around in Central Park.
I'm currently wandering around aimlessly in the park, taking a break..
On my way over though I passed a bubble tea festival that was happening...
Gotta get bubble tea now... *Bad* but easier it's so expensive.. They're price gouging!!!
*good? But more I want a drink... I have water but I want something tastier...*
**Sees Duane Reade, goes in no sole, too expensive**
** Sees McD...pass... sees sign saying any large drink for $1**
...
I'm now waking in CP while drinking a large Sprite.... and I want cake bc I'm already in NYC goddammit... might as well get some as it's in the way... And I won't get another chance until.... **Some far away date** ( I know is probably not true...)
Help?1 -
when you're in /etc/apache2/sites-available, you want to set up a second domain so you duplicate the config but you type mv instead of cp and discover it after you set up the 'second' domain

So i wasted last 24 hours trying to satisfy my ego over a shitty interview and revisiting my old job's codebase and realising that i still don't like that shit. just i am 25 and have no clue where am i heading at. i am just restless, my most of the decisions in 2023 have given very bad outcomes and i am just trying doing things to feel hopeful.
context for the interview story-----
my previous job was at a b2b marketing company whose sdk was used by various startups to send notifications to their users, track analytics etc. i understood most of it and don't find it to be any major engineering marvel, but that interviewer was very interested in asking me to design a system around it.
in my 1.2 years of job there, i found the codebase to be extremely and unnecessarily verbose ( java 7) with questionable fallbacks and resistance towards change from the managers. they were always like "we can't change it otherwise a lot of our client won't use our sdk". i still wrote a lot of testcases and tried to understand the working of major features.
BTW, before you guys go on a declare me an embarrassment of an engineer who doesn't know the product's code base, let me tell you that we are talking SDKs (plural) and a service based company here. their was just one SDK with interesting, heavy lifting stuff and 9 more SDKs which were mostly wrappers and less advanced libraries. i got tasks in all of them, and 70% of my time went into maintaining those and debugging client side bugs instead of exploring the "already-stable-dont-change" code base.
so based on my vague understanding and my even more vague memory from 1 year ago, i tried to explain an overall architecture to that interviewer guy. His face was screaming the word "pathetic" from his expressions, so i thought that today i will try to decode the codebase in 12-15 hours, publish a cool article and be proud of how much i know a so called martech system design. their codebase is open sourced, so it wasn't difficult to check it out once more.
but boy oh boy i got so bored. unnecessary clases , unnecessary callbacks static calls , oof. i tried to refactor a few classes, but even after removing 70% of codebase, i was still left with 100+ classes , most of them being 3000-4000 files long. and this is your plain old java library adding just 800kb to your project.
boring , boring stuff. i would probably need 2-3 more days to get an understanding of complete project, although by then i would be again questioning my life choices , that was this a good use of my 36 hours?
what IS a correct usage of my time? i am currently super dissatisfied with my job, so want to switch. i have been here for 6 months, so probably i wouldn't be going unless i get insane money or an irresistible company offer. For this i had devised a 2 part plan to either become good at modern hot buzz stuff in my domain( the one being currently popularized by dev influenzas) or become good at dsa/leetcode/cp. i suck bad at ds/algo stuff, nor am i much motivated. so went with that hot buzz stuff.
but then this interview expected me to be a mature dev with system design knowledge... agh fuck. its festive season going on and am unable to buy any cool shirts since i am so much limited with my money from my mediocre salary and loans. and mom wants to buy a home too... yeah kill me3 -
Decided to enter a programming context. Couldn't read the input for the first problem. Tried different language and reading the input looked even harder. Decided to go to sleep.1

Yesterday I bought a thumb drive for installing Windows 10. I've also tried booting the Windows 10 installation media from a partition with grub, and adding the storage drivers to the install.wim image, but the drivers don't install correctly and I don't get it to work. I'm on Arch Linux and a laptop.
I spent 4+ hours on that. uefi-ntfs.img, Windows 10, also tried Windows 7, gparted, cp, bla, bla, bla.
On attempt n12903813280, I open again gparted.
/dev/sdb: unrecognized disk label
Turns out somehow I damaged the thumb drive after so many writing. In just a few hours.
Dude I'm literally stuck on Linux. Get me out of here. I want to be normal and play Valorant.7 -
Sir i am a newbie student to CP. I have recently started CP and just know array , strings , loops , function and basic libraries along with logic.
Where and what roadmap shall i follow so that i can get rated nicely and quickly on codeforces?

I was thinking to read some books on algorithm and mathematics required in programming, especially for CP. After some searching I got across some books that are considered great in the field. Among the books, 'Introduction to Programming by CLRS', 'Algorithms Design Manual by Steven Skiena', 'Concrete Mathematics by Donald E. Knuth' and 'The Art of Programming by Donald E. Knuth', in which order should I read them? I've already started reading CLRS as it would be required in my college course too.5

This is an actual transcript...
Since it's way too long for the normal 5000 characters, hence splitting it up...
Infra Guy: mr Dev, could you please give some rational for update of jjb?
Dev: sparse checkout support is missing
Infra Guy: is this support mandatory to achive whatever you trying to do?
Dev: yes
Infra Guy: u trying to get set of specific folder for set of specific components?
Dev: yes
Infra Guy: bash script with cp or mv will not work for you?
Dev: no
Infra Guy: ?
Dev: when you have already present functionality why reinvent the wheel
Dev: jenkins has support for it
Dev: the jjb is the bottle neck
Infra Guy: getting this functionality onto our infra would have some implications
Dev: why should I write bash script if jenkins allows me to do that
Dev: what implications ??
Infra Guy: will you commit to solve all the issues caused by new jjb?
Dev: you show me the implications first
Infra Guy: like a year ago i have tried to get new jjb <commit_url>
Infra Guy: no, the implications is a grey area
Infra Guy: i cant show all of them and they may hit like in week or eve month
Dev: then why was it not tackled
Dev: and why was it kept like that
Infra Guy: few jobs got broken on something
Dev: it will crop up some time later
Dev: if jobs get broken because of syntax
Dev: then jobs can be fixed
Dev: is it not ???
Infra Guy: ofc
Infra Guy: its just a question who will fix them
Dev: follow the syntax and follow the guidelines
Dev: put up a test server and try and lets see
Dev: you have a dev server
Dev: why not try on that one and see what all jobs fails
Dev: and why they fail
Dev: rather than saying it will fail and who will fix
Dev: let them fail and then lets find why
Dev: I manually define a job
Dev: I get it done
Infra Guy: i dont think we have test server which have the same workload and same attention as our prod
Dev: unless you test how would you know ??
Dev: and just saying that it broke one with a version hence I wont do it
Infra Guy: and im not sure if thats fair for us to deal with implication of upgrading of the major components just cause bash script is not good enough for u
Dev: its pretty bad
Infra Guy: i do agree
Infra TL Guy: Dev, what Infra Guy is saying is that its not possible to upgrade without downtime
Infra Guy: no
Dev: how long a downtime are we looking at ??
Infra Guy: im saying that after this upgrade we will have deal with consequences for long time
Infra Guy-2: No this is not testing the upgrade is the huge effort as we dont have dev resources to handle each job to run
Dev: if your jjb compiles all the yaml without error
Dev: I am not sure what consequences are we talking of
Infra Guy: so you think there will be no consequences, right?
Dev: unless you take the plunge will you know ??
Dev: you have a dev server running at port 9000
Infra Guy: this servers runs nothing
Dev: that is good
Dev: there you can take the risk
Infra Guy: and the fack we have managed to put something onto api doesnt mean it works
Dev: what API ?
Infra Guy: jenkins api
Infra Guy: hmmm
Dev: what have you put on Jenkins API ??
Infra Guy: (
Dev: jjb is a CLI
Infra Guy: ((
Dev: is what I understand
Dev: not a Jenkins API
Infra Guy: (((
Dev: (((((
Infra Guy: jjb build xmls and push them onto api
Infra Guy: and its doent matter
Dev: so you mean to say upgrading a CLI is goig to upgrade your core jenkisn API
Dev: give me a break
Infra Guy: the matter is that even if have managed to build something and put it onto api
Infra Guy: doesnt mean it will work
Dev: the API consumes the xml file and creates a job
Infra Guy: right
Dev: if it confirms to the options which it understands
Dev: then everything will work
Dev: I am actually not getting your point Infra Guy
Infra Guy: i do agree mr Dev
Dev: we are beating around the bush
Infra Guy: just want to be sure that if this upgrade will break something
Infra Guy: we will have a person who will fix it
Dev: that is what CICD is supposed to let me know with valid reasons
Dev: why can't that upgrade be done
Infra Guy: it can be done
Infra Guy: i even have commit in place3 -
I tried to copy some files from a corrupted microsd... In windows the hole Explorer died and I had to restart the pc, then I startet the copy on linux, the corrupted files were shown and the working ones cp has success. Fuck Windows.

(first day at Command line)
cp /path/file
yes :) no destination..because Windows user algorithm
first ctrl+c then ctrl+v
took 2 hrs to figure out what's wrong -
Android didn't find it all that funny, that I was copying a 6 GiB file locally
Couldn't even load the settings app while `cp` did it's thing1 -
someone gets in my Discord server, asks "can anyone download a file for me? DM me" in the bot trap, and leaves.
Is it worth the effort of trying to track this guy down so I can get new malware or is it not worth the risk of CP?4 -
How will I get a better Dev job in 12 months, by making projects or by practicing competitive programming?8
-
why can't i ever have a successful make build even with all dependencies satisfied. took TWO weeks of faffing with libdvdcss becasue it couldn't find libc6. I think at one point i might have inadvertently deleted libc6 doing an ln -s in reverse order. I know i got kernel panics trying to cp it back before discovering apt -reinstall cause like fuck was i gonna purge and reinstall my whole system. ANYWAY couldn't find where the libc6 dependency was in the build script but did find a way to tell it to ignore missing deps. although copyright lawyers needed the guillotine so this would never have been an issue1

What you do ?
Competitive programming (CP) or Functional programming (FP)?
And if you FP then how much competitive programming you think you need in your job or whatever your current scenario is .14 -
Dear Lord, please stop people from enforcing standards and bypassing them themselves.
Take kubernetes for example. Since v1.24 CRI has been announced as the standard, and kubernetes is shifting to live by it.
But it's not.
Yes, it's got the CRI spec defined and the unix://cri.sock used for that standardised communication. What nobody's telling you, is that that socket MUST be on the same runtime as the kube. I.e. you can't simply spin up a dockerd/containerd/cri-o server and share its CRI socket via CIFS/NFS/etc. Because kube-cp will assume that contained is running on the same host as cp and will try to access its services via localhost.
So effectively you feed the container via a socket to another machine, it spins up the container and that container tries to
- bind to your local machine's IP (not the one's the container is running on)
- access its dependencies via localhost:port, while they are actually running on your local machine (not the CRI host)
I HOPE this will change some day. And we'll have a clear cut between dependencies and dependents, separated by a single communications channel - a single unix socket. That'd be a solution I'd really enjoy working with. NOT the ip-port-connect-bind spaghetti we have now.4 -
I like to look back at what I considered 'programming' back in high school compared to what I'm doing now as a almost CP college graduate
Still know absolutely nothing. But that's immensely more than what I did as the best student in my high school programming elective and the barely accomplishments i achieved as a high school intern at CMU
I still have a copy of some my old high school 'code' (more like data trash)on a flash drive just for memory's sake -
When you start doing cp / noob at it:
Thoughts in my mind
- spending hrs to solve the problem
- should I see the solution. No no how can I build the logic then?
- think try
- told my friend,
He: oh tell me the problem
(After seeing the problem stmt)
5-10 mins scribbling with code
He: There you go it's that simple
Me: really! This is easy. But why I was not able to solve then :|8 -
I am trying to decompose a 3D matrix using python library scikit-tensor. I managed to decompose my Tensor (with dimensions 100x50x5) into three matrices. My question is how can I compose the initial matrix again using the decomposed matrix produced with Tensor factorization? I want to check if the decomposition has any meaning. My code is the following:
import logging
from scipy.io.matlab import loadmat
from sktensor import dtensor, cp_als
import numpy as np
//Set logging to DEBUG to see CP-ALS information
logging.basicConfig(level=logging.DEBUG)
T = np.ones((400, 50))
T = dtensor(T)
P, fit, itr, exectimes = cp_als(T, 10, init='random')
// how can I re-compose the Matrix T? TA = np.dot(P.U[0], P.U[1].T)
I am using the canonical decomposition as provided from the scikit-tensor library function cp_als. Also what is the expected dimensionality of the decomposed matrices.1 -
I just wanted to share it with my fellow devs,
I'm peacefully retiring from COMPETITIVE CODING. After two years of rigorous effort on CP, I don't think I improved a lot, although I learned some new DS and Algos. My bad that I assumed CP holds more importance than just being a sport.
It feels to me that I kinda wasted my two years, I could've spent it on some development or ML.
Now, I've started to realize that I can't think faster as other coders do. I tried a lot, but it's all dumped now. Maybe I'm not made for CP or maybe I simply suck at it.
Any sorta advice will be highly appreciated...3 -
p4 add <new file>
cp <old file> <new file>
p4 delete <old file>
p4 submit
That how you tell someone “GO TO HELL!” in perforce commands.2 -
Since tar is apparently faster than cp
It’s making me wonder
Which is faster
Md5/sha with a comparison against the copied files
Or diff ?5 -
Best
- Started a blog, networking and public learning
- Got an Internship
Worst
- DSA and CP fcuked me hard and I started questioning my ability to write code
- Wasted first six months in academics and uni stuff
- Thought about quitting programming and start UI/UX at one point -
Which app can i use to run cp in Android??
In many apps i cant make the programs like enter a number for input and all☹5 -
teacher: You know CP?
student: yes
teacher: fix the bugs
student: (after checking all code) I know computer programming, not competitive -
