pm: our client wants a proprietary pdf compression app.
me: Okay gimme 3 days and some sample PDFs.
pm: they won't supply any sample PDFs because they contain confidential information.
me: okay fine, I'll download some from the interwebs.
** 3 days later **
me: here is the pdf compression app. all done and works with all of about 100 PDFs we tested with.
pm: okay great I'll have the client take a look.
** half and hour later **
pm: the client said that the compression app errors out.
me: okay I'll go look at the server logs to see what's up.
** 10 seconds later **
me: what the shit is a "foxit phantompdf" file.
pm: it's the proprietary pdf format that they are using.
me: oh joy. I'll go try to find some sample files and see if I can fix it.
** 1 hour later, no sample files found **
pm: got anything?

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 ;;22 -
Story about an obscure bug: https://twitter.com/mmalex/status/...
"We had a ‘fun’ one on LittleBigPlanet 1: 2 weeks to gold, a Japanese QA tester started reliably crashing the game by leaving it on over night. We could not repro. Like you, days of confirmation of identical environment, os, hardware, etc; each attempt took over 24h, plus time differences, and still no repro.
"Eventually we realised they had an eye toy plugged in, and set to record audio (that took 2 days of iterating) still no joy.
"Finally we noticed the crash was always around 4am. Why? What happened only in Japan at 4am? We begged to find out.
"Eventually the answer came: cleaners arrived. They were more thorough than our cleaners! One hour of vacuuming near the eye toy- white noise- caused the in game chat audio compression to leak a few bytes of memory (only with white noise). Long enough? Crash.
"Our final repro: radios tuned to noise, turned up, and we could reliably crash the game. Fix took 5 minutes after that. Oh, gamedev...."5 -

devRant on a HoloLens!
The HoloLens is really cool, I was allowed to use it after a short hackathon. I am still surprised, but it works great and the concept feels natural after a short moment - web browsing is not recommended as no website is optimized for mixed reality (yet?).
Sorry for the low quality photo (it is not the compression algorithm's fault this time).

Apple you drove of delusional suckers! When will your retarded fashion devices finally support WEBP?!
A gallery page with images, and thanks to WEBP, it's 408 kB. Because Google made WEBP and handed out a well documented CLI FOSS compression tool that even can convert the source PNGs to lossy WEBP with bloody transparency. Well done, Google!
Except that Apple's shitty management can't take it that Google actually made something nice, so no WEBP. Instead, JPEG-2000 that enjoys nearly no fucking tool support. The free tools that even can deal with that mostly don't support transparency, and the encoder sucks donkeys so that JPEG still fucks JPEG-2000 big time.
So it's JPEG with matching background for iOS. Fine, but since JPEG's blocky artifacts are much more visible, the compression can't be that high, and it's 769 kB. That's 88% more image data for Shittari than for non-retarded browsers and even Edge! EDGE!!
Oh and if the user changes light/dark system mode according to surrounding light conditions, guess what happens? Yep, since JPEG doesn't support transparency, now it's different JPEGs with dark background via the media query in the "picture" element, and it's another 754 kB download. Bloody 1523 kB instead of 408 kB, that's a factor of 3.7!
Fuck your ass Crapple, with an electric eel!19 -

*Hopefully devRant's compression of images doesn't ruin it.*
The center of the trackpad simply feels smooth because of the oil from my finger.
The keys are oily as well. Specifically the space bar and backspace.

My worst experience was at my job where they told me I have to move to a permanent position from 3 years of contracting without a specific offer.
Why is that bad? In my country it means approximatly 40% lower wage.
I came into the job with PHP knowledge when they were looking for Perl on a project one year behind schedule. I learned the language and finished working demo in 6 weeks.
After that, every project that was ever assigned to me was done within 5-15% of the allocated time. I'm not kidding here. My manager loved be, because I was reliable, fast and I even 'accidentaly' solved other problems, like for instance I developed simple syslog search tool and benchmarked zip algos for reading speed, and the fastest had 70% better compression than the algo used before (gzip into plzip on 1-2gb files). That solved anothet problem - syslog servers did not have enough disk space and they didn't have money to upgrade the server.
The number of projects I touched or developed was over 20.
I also lead and developed our team's most successful tool, that every customer was throwing money to buy, while cutting down costs everywhere.
And after three years of that, my manager says that there are no more money for contractors. And the only possibility is going for employment. Without any specific offer! Just 'we cant do this anymore'.
Which I understand, that can happen in corporation, but ffs after all I've done, I expected warmer attitude. Not like 'you may have to leave, since we do not really care'.
I liked the people there, even though the corporation environment was lacking in many respects, but I wanted to help our local branch with everything I could and they gave up on me like that.
So I started looking elsewhere and I found a startup which offered 6 times the money I had in my previous job and promises to relocate me to USA. Which is the best thing that has happened to me that year and second best in my whole life!3 -

TL;DR: Printers suck. MS-Word sucks.
Yesterday I wanted to print a few participation certificates for my blender project students.
*Turns on printer, runs downstairs, gets paper, runs upstairs, puts paper in*
So I tried to print in word. Nothing happened. Printer was online. I checked queue: Nothing.
*a couple of tries later*
Okay, fuck it! I export it as a pdf and open it in edge (8 times. 8 documents. Edge is a neat pdf-viewer, fight me). I press print on one. It works. I print the others and check: They look shit. The images look like 25% resolution and 50% jpg compression. I check word.
It by default exports in low quality. Yea, thanks for asking me. I export pdfs again and check "high quality". Open them, print. Done.
These were like 30 wasted minutes and print color. And paper.
Btw they look fucking neat. I can't show them right now but gradient text headline, project name is a rendered and edited 3D object :D4 -

Since I love playing music on my piano, and because I love programming, I created this:
A program which uses YIN (some kind of FFT algorithm) to create this audio spectrum. It can read from any audio source, be it microphone or the computers audio output. There are 3 lines in the graph at the bottom:
Both magenta lines, both are movable, allow you to just select a part of the audio spectrum to show, which is very useful if you just want to get the chords out of a song, or just the notes.
The cyan line can also be moved, it tells the program the lower limit to calculate the actual notes/chords from the frequency bars (which are calculated by the FFT algorithm).
In the top right of the spectrum is, in magenta color, one single note. It shows the currently loudest frequency as a note.
In the top right corner is a simple image of a one-octave piano. Every note over the cyan line will be shown on this piano. This is very useful for chords.
Since compression will fuck this image up, here is a link: https://i.gyazo.com/fbbee76faecbac3...
What do you think about it? I fucking love it.

There should be an open source, Linux based Printer operating system. Like OpenWRT for routers, also works with almost every device in the wild.
This would be such a relief for everyone. Come on, most printer firmwares are crap.
Remember Scannergate? Yep, the one about professional xerox scanners changing numbers in scanned document. Went unnoticed for 8 years and affected almost every workcenter even in the highest compression setting. Just because they wanted to save a few bytes by using pattern matching.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 -

In my last year of high school (for those familiar with the Indian education system, that's Class 12), for my final project I made an image compressor/decompressor in Turbo C++ that used a discrete Fourier transform (DCT, actually) to work on 8x8 px blocks of images. I based it off some stuff I found about how JPEG compression works. It worked even better than I'd hoped even though it was slow as molasses (I programmed a naive Fourier transform instead of using a FFT variant). I remember jumping with joy all around my room at 3 o'clock in the morning like an excited gas molecule in a box. Fun times.

Okay so after a few days of thinking I think I'm sure about what I'm about to write :
Best : Discovering how to use streams while making a service that should extract a tar.gz, extract the tar.gz within it, filter the extracted files and correct some of them, then compress each folder as tar.gz and compress all the archives as .zip. The amazing thing for me is that with streams I could do all the operations in just two passes, maybe one if I had more time, saving disk writing time.

Why are GIFs still a thing?!? I mean don't get me wrong, I don't have anything against short, audioless videos but why GIF?
GIF only provides a lossless per-frame compression so the performance sucks really bad. For example a 1 MB GIF converted to MP4 is only 100 KB.
So that's why they take longer to load and have so bad quality.3 -

The real web development is optimising the shitty front end code.
The task assigned to me is optimisation of dashboard page of website which was developed by freenlancers.(end of contract from their side)
The front end is mess. Individual js files (bootstrap, popper, jQuery, jQuery ui, loader and main) loading in production inside head tag of html file
No text compression.
Every template has random number of their own js files in any block of template. Nothing structured. There will be fantastic waste of time figuring out file dependencies.
Same with css files. Some are scss, some plain css. No compression. No proper modules.
Basically, I have to go through 25-30 html files. Then understand, which template is extending which one. Go through all js and css files in each html file and again understand dependencies between them
This is gonna be real fun.2 -
Ideas I've had over the years that could pan out and be useful:
SMS-DB: Stands for SMS-Data Burst. Used to allow those with low cell signal or no data plan to transfer data between a phone and some client via the standard SMS text space. Would be slow, but would act kinda like dial-up over SMS (as mobile lines are compressed on all service levels, even LTE, so traditional dial-up wouldn't work!) I have a general idea on how packets would be laid out, but that's about it so far...
everything2PNG: Allows one to transpose any file's data into a PNG with a 3 byte per pixel (full color RGB), which allows for a "compression" of sorts (about 91, 93% on preliminary tests) AND allowing further, more efficient compression of the resulting file. (Plus... it's just kinda cool to see files transposed as PNGs.) I actually have a simple transposer to go to PNG, but can't yet go back. Large files (around 600MB) use upwards of 4GB with efficient paging and other optimizations via NumPy so far, so it's not *viable* yet, but it's coming along nicely.
RPi-GPIO Interconnection Bus: A master/slave or round robin method to allow for Raspberry Pis to communicate using GPIO, which can help free up network bandwidth in RPi cloud computing clusters. At most, this'd allow for 4 bits used for pushing to the GPIO "bus", and 4 bits used for pulling from the "bus". 8 pins total are usually unused minimum, so either 3 or 4 pins for upload, 3 or 4 for download, and potentially 1 or 2 for commands, general non-data communication, etc. I made a version of this concept using Round Robin for a client, but it was horribly slow. (I also don't have distribution rights for the code, so i'm working from scratch.) Definitely doable. -

mkfs.btrfs ~/Imgs/myproject1.btfs
mount -o defaults,noatime,autodefrag,compress,compress-force,inode_cache ~/Imgs/myproject1.btfs ~/Development/Project1
Well ... little overhead, gzip compression, saved a lot of space ... but wait ... why do my btfs files consume more and more space?
Hmm ... time for a little bash and my beloved systemd timers.
for f in `find . -type f -name "*.btfs"`
do
project=${$f%.*}
btrfs balance start -v -dusage=100 ~/Development/$project
btrfs balance start -v -musage=100 ~/Development/$project
fstrim ~/Development/$project
fallocate -d -v $f

So when I started at my current company, I was the second developer in the company. My job is to handle the embedded development side of our product. The existing code base? Made in fucking China. All of the comments were in Chinese too. They had implemented Huffman compression incorrectly and AES CBC encryption incorrectly as well. It was seriously some of the worst code I've ever seen. I remember one gem I found:
Int header = *(*int) "MGIK";

Just switched from gzip to brotli compression and I have to say I am impressed! Google may suck in some regards but brotli is awesome ☺️2

>the human mind cannot process non-Euclidean laws of physics and space
Yes it can. Non-Euclidean terms don't phase me. I've played too many games like Antichamber, removing laws of physics/the universe doesn't phase me.
How do I do these fucking things???3 -
I have always wanted too work on lossless compression technology. I have just never had the time to go after it. Or do I really know where to start lol1

Oh yeah, I wanna rant... What is this awful image compression on DevRant?! A lot of time, images posted by ranters are illegible if they contains text. If we are lucky enough, the ranter will then post an Imgur, else... It would be really great to get an image quality equal to DevRant quality... Please!2

Idk if it's a weird compression issue or what but when I mod an apk using apktool and recompile it, sign it and use it, the app runs unusably slow. Is there any way to fix this?2

Guys!
Help me understand something.
I used this App on my phone to buy a few things. I ended up buying nothing but did search a bunch of stuff.
I removed that app
Now, I am using another app (for video compression) and its shows adds.
Here is the interesting bit: its showing add for that App/website and its showing all the items I searched for 😮
How does one app knows what i searched for in another app?3
