TCP vs UDP

wk87 is a dangerous topic for me, i've been through a lot. I apologise for what I am about to inflict on this network over the coming week.

Most incompetent co-worker, candidate 1, "T".

T was an embedded C developer who talked openly about how he's been writing code since he was 14, knew all the C system libraries and functions like the back of his hand. For the most part, he did ... but not how to actually use them, as (based on his shocking ... well everything) he was inflicted by some sort of brain disorder not yet fully understood by medical science. Some highlights:

- Myself and the CTO spent 4 days teaching him what a circle buffer was and how to build one.
- His final circle buffer implementation had about 3 times as much code as he actually needed.
- When the code was running too slowly on the device, we didn't try find any performance improvements, or debug anything to see if there was anything taking too long. No not with T, T immediately blamed TCP for being inefficient.
- After he left we found a file called "TCP-Light" in his projects folder.
- He accused the CTO of having "violent tendencies" because he was playing with a marker tossing it up in the air and catching it.
- He once managed to leave his bank statements, jumper and TROUSERS in the bathroom and didn't realise until a building wide email went out.
- He once .... no hang on, seriously his fucking trousers, how?
- He accused us all of being fascists because we gave out to him for not driving with his glasses, despite the fact his license says he needs to (blind as a bat).

... why were his trousers off in the first place? and how do you forget ... or miss the pile of clothes and letters in a small bathroom.

Moving on, eventually he was fired, but the most depressing thing of all about T, is that he might not even be top of my list.

Tune in later for more practiceSafeHex's most incompetent co-worker!!!

Every IT admin's wish

You see a web, I see:

CLIENT: TCP SYN
SERVER: TCP SYN ACK
CLIENT: HTTP Get
SERVER: HTTP Response
...
CLIENT: TCP FIN
SERVER: TCP FIN ACK

All I’m saying is that this spider has a clear understanding of Transfer Control Protocol.

The ability to slap people through tcp/ip.

I feel like a fucking abomination at the moment.

I have been working on an app that is almost like Wireshark. More so for practice than anything else.

I decided that today I would try it out on the network here at my house, so I started the packet sniffer and wanted to see what was going on. I was checking for unencypted text (like telnet and whatnot) and came across this odd address that I hadn't seen before.

I did something that I shouldn't have done, and I fucking clicked and did the equivalent of "follow TCP stream" on wireshark. I fucking went and looked what the text being sent over this fucking network was.

It was my girlfriend, using fuck knows what messenger, but it was unencrypted. I just found out that she is cheating on me. I don't want to go into what the texts exactly say, because it fucking hurts me deep down.

Why didn't she just use whatsapp or something, fuck man. I really don't need this in life at the moment. I am genuinely trying to get my shit in order, I have been coding my ass off at night for extra money to make it, I have been working overtime where I can - fuck I have even tried sucking up to management (I would never do this under normal circumstances) - and to top this off, the motherfucking tax man is giving me hell.

Fuck sakes.

If you want to cheat, fucking do it properly. Because I am in a state of pure sadness and hatred and the moment - and I don't know what the fuck to do.

So I decided to give Linux a try again.

Created live usb. Prepared myself to go through all the hassles at the beginning.

Booted in live USB. I can't see mouse cursor.

Searched in google, apparently a common problem with GTX 1070/1080 graphics cards.

Installed proprietary nvidia drivers with keyboard only. Took me about 20 minutes.

Finally managed to get the mouse cursor and install ubuntu. Time to boot and smell the fresh air of linux again.

Sound card doesn't work. Even the integrated mobo sound card doesn't work. Looked for a solution, found the bug in lunchpad but not solution yet. Everyone recommending to buy an external sound card.

I can't code without music. Decided to remove linux.

Booted back to Windows and removed linux partition. That fucked up my bootloader although I installed linux's efi loader completely separately.

Now I am sitting in front of my computer, with black grub screen, while trying to make a Windows 10 usb with my 7 years old broken laptop.

Next time I see a rant about Windows 10 that glorifies linux, I swear I'm gonna smack your face over standard TCP/IP

I'm pretty sure it was already posted in here, but I found it today

Did you get it?

Are you ready to get my up vote
Yes I'm ready to get your up vote

So this was a couple years ago now. Aside from doing software development, I also do nearly all the other IT related stuff for the company, as well as specialize in the installation and implementation of electrical data acquisition systems - primarily amperage and voltage meters. I also wrote the software that communicates with this equipment and monitors the incoming and outgoing voltage and current and alerts various people if there's a problem.

Anyway, all of this equipment is installed into a trailer that goes onto a semi-truck as it's a portable power distribution system.

One time, the computer in one of these systems (we'll call it system 5) had gotten fried and needed replaced. It was a very busy week for me, so I had pulled the fried computer out without immediately replacing it with a working system. A few days later, system 5 leaves to go work on one of our biggest shows of the year - the Academy Awards. We make well over a million dollars from just this one show.

Come the morning of show day, the CEO of the company is in system 5 (it was on a Sunday, my day off) and went to set up the data acquisition software to get the system ready to go, and finds there is no computer. I promptly get a phone call with lots of swearing and threats to my job. Let me tell you, I was sweating bullets.

After the phone call, I decided I needed to try and save my job. The CEO hadn't told me to do anything, but I went to work, grabbed an old Windows XP laptop that was gathering dust and installed my software on it. I then had to build the configuration file that is specific to system 5 from memory. Each meter speaks the ModBus over TCP/IP protocol, and thus each meter as a different bus id. Fortunately, I'm pretty anal about this and tend to follow a specific method of id numbering.

Once I got the configuration file done and tested the software to see if it would even run properly on Windows XP (it did!), I called the CEO back and told him I had a laptop ready to go for system 5. I drove out to Hollywood and the CFO (who was there with the CEO) had to walk about a mile out of the security zone to meet me and pick up the laptop.

I told her I put a fresh install of the data acquisition software on the laptop and it's already configured for system 5 - it *should* just work once you plug it in.

I didn't get any phone calls after dropping off the laptop, so I called the CFO once I got home and asked her if everything was working okay. She told me it worked flawlessly - it was Plug 'n Play so to speak. She even said she was impressed, she thought she'd have to call me to iron out one or two configuration issues to get it talking to the meters.

All in all, crisis averted! At work on Monday, my supervisor told me that my name was Mud that day (by the CEO), but I still work here!

Here's a picture of the inside of system 8 (similar to system 5 - same hardware)

A tcp packet walks in to a bar and says “I want a beer”, barman says “you want a beer?” and tcp packet says “yes, a beer” .

In high society, TCP is more welcome than UDP. At least it knows a proper handshake.

A bunch of TCP packets go into a bar, until it’s overcrowded. The next day, half as many go in.

A bunch of TCP packets walk into a bar. The bartender says, “Hang on just a second, I need to close the window.”

When I try to send SYNs to chicks, I don’t get any ACKs. Just FINs and RSTs.

IP packet with TTL=1 arrives at bar. Bartender: “Sorry, can’t let you leave…and you don’t get any beer either…” 

The worst part about token ring jokes is that if someone starts telling one while you are telling yours, all joking stops.

The great thing about TCP jokes is that you always get them.

The problem with TCP jokes is that people keep retelling them slower until you get them.

I would tell some UDP jokes too but I never know if anyone gets them

The best thing about UDP jokes is that I don’t care if you get them or not.

I had a funny UDP joke to tell, but I lost it somewhere...

The sad thing about IPv6 jokes is that almost no one understands them and no one is using them yet.

I tried to come up with an IPv4 joke, but the good ones were all already exhausted.

A DHCP packet walks into a bar and asks for a beer. Bartender says: “here, but I’ll need that back in an hour!

DHCP jokes only work when there is only one person telling them

The worst part of SSH jokes is that, even when they're not funny, you suck it up and just pretend they were anyway.

The problem with token ring jokes is you need to wait your turn to laugh

I’d make a joke about UDP, but I don’t know if anyone’s actually listening…

Me: Hey Dave, wanna hear a TCP joke?
Dave: Uhh, sure...
Me: OK I'll tell you a TCP joke..
Dave: Please don't.
Me: Are you ready to receive my TCP joke?
Dave:...
Me: OK I'm sending my TCP joke. It'll be 4 words long and 27 bits large.
Dave:... Screw this, I'm going home now.

You won’t get it. But I don't care.... :)

Hello, would you like to hear a TCP joke?

Yes, I'd like to hear a TCP joke.

OK, I'll tell you a TCP joke.

OK, I'll hear a TCP joke.

Are you ready to hear a TCP joke?

Yes, I am ready to hear a TCP joke.

OK, I'm about to send the TCP joke. It will last 10 seconds, it has two characters, it does not have a setting, it ends with a punchline.

OK, I'm ready to hear the TCP joke that will last 10 seconds, has two characters, does not have a setting and will end with a punchline.

I'm sorry, your connection has timed out... ...Hello, would you like to hear a TCP joke?

Hello, would you like to hear a TCP joke?

Would you like to hear a TCP joke?

Anyone looking for something interesting to do???

Step 1) understand how basic circuitry works on a bread board nothing too fancy. ( Implement NAND, AND, ADDER, SUBTRACTOR)

Step 2) learn about microprocessors and how OS works

Step 3) learn assembly

Step 4)write a basic assembler and understand how loaders and linkers works !

Step 5) write a kernel with very basic features like memory management and process management and some drivers for IO

Step 5) write an emulator for some simple systems .! ex chip-8.

Step 6) read about compiler theory and automata

Step 7) write a basic Python interpreter that compiles (not interpreter) to native assembly.

Step 8) implement TCP stack .

Step 9) learn as much as u can about complexity measurement ), data structures and algorithms using C or C++ it's very important ( familiarity with pointers and thus computer memory )

Step 10) learn any high level language of choice like Python or Ruby.

Step 11) stop debating over tabs vs spaces , emacs vs vim , angular vs vue, php vs Python , OOps vs procedular vs functional ( just know about all of them and when to use but don't fucking debate over which one is superior )..

Step 12) live happily and be healthy.

I spent a month tracking down "slow internet".

Everybody thought the users in that office were just stupid (mostly because they were) and such were ignored when lamenting "the internet is slower now that we have fiber!"

But dammit it *was* slow. Every time I had to download something in that office, it felt like it took twice the time it should.

Ping the router; it's fine. Ping 8.8.8.8: ~50ms no loss. Speedtest.net showed 100 up 100 down. Transfer files between PCs, no local network issues. Go back to my office and transfer files (over the WAN), it's slow!

So I pop open Wireshark. Mad packet loss. All my wat. Ping their router over WAN... no packet loss.

I went back and forth with these various tests for a couple weeks until I narrowed it down to one weird possibility:

The ONT is dropping *only* sequential TCP packets.

I spent the next two weeks convincing our ISP this was the case. Eventually they ripped out the equipment and replaced it. Apparently that whole business park had been suffering for a year.

So yeah. It was slower on fiber. WTF.

Eureka! The IBM 5150 is on the internet!

Prof: alright class our topic for the day is all about TCP. What's TCP?

Me: Our topic for the day.

"Hi, I'd like to hear a TCP joke."
"Hello, would you like to hear a TCP joke?"
"Yes, I'd like to hear a TCP joke."
"OK, I will tell you a TCP joke."
"Are you ready to hear a TCP joke?"
"Yes, I am ready to hear a TCP joke."
"OK, I am about to send the TCP joke. It will last 10 seconds, has 2 characters, it does not have a setting, it ends with a punchline."
"OK, I am ready to get the TCP joke that will last 10 seconds, has 2 characters, does not have a setting, and ends with a punchline."
"I'm sorry, your connection has been timed out."
"Hello, would you like to hear a TCP joke?"

When 500 ms have passed and you have not yet received the ACK

Python: "I'm platform independent"
Me: "Cool, can you set the TCP keep alive to 1 second"
Python: "Go ask the OS lol"

Ohhh tcp

That moment when you realise:
money != Happiness
Stickers === Happiness

Mother of god.

I spent hours and hours last week to try and get OpenVPN working. I mean, OpenVPN is working perfectly fine (on a VirtualBox (nope no vmware for me on servers) machine on a friends' dedicated server) but it wouldn't get through! As in, every forwarding/firewall rule just didn't work.

Was seriously about to lose my shit just now when I suddenly noticed the term 'TCP' in a forwarding rule.

Looked at the .ovpn file: proto udp

I added the exact same rule for UDP as a forward within VirtualBox.

It worked.

Well, there goes quite some hours 😐

And solely because I didn't realise that I setup a forwarding thingy for the wrong protocol.

I feel very stupid now :(

Too damn hilarious

I would like to tell you a UDP joke, but you might not get it..

Experience that made me feel like a dev badass?

Users requested the ability to 'send' information from one application to another. Couple of our senior devs started out saying it would be impossible (there is no way to pass objects across a machine's memory boundary), then entertained the idea of utilizing the various messaging frameworks such as Microsoft's ServiceBus and RabbitMQ, but came up with a plan to use 2 WebAPI services (one messenger, one receiver) along with a homegrown messaging API (the clients would 'poll' the services looking for message) because ServiceBus, RabbitMQ, etc might not be able to scale to our needs. Their initial estimates were about 6 months development for the two services, hardware requirement for two servers, MSSQL server licenses, and padded an additional 6 months for client modifications. Very...very proud of their detailed planning.

I thought ...hmmm...I've done memory maps and created simple TCP/IP hosts that could send messages back and forth between other apps (non-UI), WPF couldn't be that much different.

In an afternoon, I came up with this (see attached), and showed the boss. Guess which solution we're going with.

The two devs are still kinda pissed at me. One still likes say as I walk in the room "our hero returns"....frack him.

Me: Why is there such a delay between the app and the hardware device?

Colleague: Ah, same old same old, TCP is just an inefficient protocol. We should stop development and build our own replacement to TCP.

(PS. The actual problem was his code)

~TCP~
A: SYN
B: ACK/SYN
A: ACK

~The French~
A: Ça va ?
B: Ça va / Ça va ?
À: Ça va

Unambiguity scores:
TCP - 1
French - 0

TCP Jedi: Master, how are you?
UDP Jedi: Good i am.

Windows: aah nope.

"Oh God maybe the bloody HP thing overheated again"
*takes laptop from beneath the desk indent*

Well.. okay. Can I log in from my phone?

*fires up Termux*
*logs in just fine*

What the fuck... Literally just now I added the laptop's ECDSA key into the WSL known_hosts by trying to log into it, so it can't be blocked by that shitty firewall (come to think of it, did I disable that featureful piece of junk yet? A NAT router * takes care of that shit just fine Redmond certified mofos).. so what is it again.. yet another one of those fucking WanBLowS features?!!

condor@desktop $ nc -vz 192.168.10.30 22

ARE YOU FUCKING FOR REAL?!

Fucking Heisen-feature-infested piece of garbage!!! Good for gaming and that's fucking it!

Edit: (*) this assumes that your internal network doesn't have any untrusted hosts. Public networks or home networks from regular users that don't audit their hosts all the time might very well need a firewall to be present on the host itself as well.

When people finish their rants with Fin I feel like I need to comment FIN-ACK to complete the TCP session.

Oh shit.. I need keyboard and mouse for this :') fuck me I guess... Long live planning ahead. Does there exist a KVM over TCP/IP yet? 😅

IP in a bottle :D

So I've been playing some DnD with friends.
And we've been working with some lego characters, whiteboard markers and plastic sheets to draw on.

But that's always a mess:
The ink was old and did not come off again for the most part
The sides of the map curled up and and made the lego character fall over
The lego characters were too big
And more...

So I thought, why not make it digital?

And so I did.
I used UWP to make a master and a client, both using the Windows Ink api to be able to draw.
Some circles with an initial served as characters, and everything was synchronized using a TCP library I wrote half a year ago.

Yesterday we tried it out.
We all (including me) were sceptical if it would work well because the 'analog' clumsy way we did it before does have a certain charm.

But at the end we were all very enthousiastic about it and we'll be using it next time too!
It's awesome to be able to create programs for your own use :D
That's why being able to program is such a great thing!

Now I need to restructure everything, make it more efficient, add a turn order display, make the map zoom- and moveable and more and more....

UDP vs TCP

I have in my head parts of a game, I'd love to build. A top-down space colonization game. You control various spacecrafts and build spacestations etc. to expand your control.
The catch is that you have limited direct controls in-game. Most of the "gameplay" consists of having your own piece of software running somewhere, communicating with the API and controlling your colony.
Similar to Screeps, but I don't like the limitations of writing JavaScript and uploading it to the service. I'd love for the user to have free control of what language to use. They just need to be able to create a TCP socket and communicate with the API

Rant? I don't think so.

By heavens creating your own api server with the Go standard lib is so easy it should be fucking criminal.

Now....on to add authentication and a nice frontend stack(prob React) to make it all spiffy and show it to my manager and see if she lets me put this shit to use at work.

It will make it more interesting. It took me nearly 1 hour to get what I needed from the docs, build it using the net package first(das right babe, pure TCP) and just a couple of minutes more for net/http and boom. Ferching info and shit left and right

Man I love this shit. Wish I could do this for a living. Stuck fucking around with css, Java and php at work instead ;____;

I hate interviewing..

The first sentence of the candidate was, that he wanted to speak in english instead of german. Great start if you stated something else in the application.

And his english was even worse than mine.

And as expected from his tags in the application, he had a broad knowledge base. From IoT, LTE, node.js TCP, Java, Ruby, Python, to VLAN and firewalls.

Guess what, he had no in depth knowledge for the required job. Suprise!

It has been bugging the shit out of me lately... the sheer number of shit-tier "programmers" that have been climbing out of the woodwork the last few years.

I'm not trying to come across as elitist or "holier than thou", but it's getting ridiculous and annoying. Even on here, you have people who "only do frontend development" or some other lame ass shit-stain of an excuse.

When I first started learning programming (PHP was my first language), it wasn't because I wanted to be a programmer. I used to be a member (my account is still there, in fact) of "HackThisSite", back when I was about 12 years old. After hanging out long enough, I got the hint that the best hackers are, in essence, programmers.

Want to learn how to do SQL injection? Learn SQL - write a program that uses an SQL database, and ask yourself how you would exploit your own software.

Want to reverse engineer the network protocol of some proprietary software? Learn TCP/IP - write a TCP/IP packet filter.

Back then, a programmer and a hacker were very much one in the same. Nowadays, some kid can download Python, write a "hello, world" program and they're halfway to freelancing or whatever.

It's rare to find a programmer - a REAL programmer, one who knows how the systems he develops for better than the back of his hand.

These days, I find people want the instant gratification that these simpler languages provide. You don't need to understand how virtual memory works, hell many people don't even really understand C/C++ pointers - and that's BASIC SHIT right there.

Put another way, would you want to take your car to a brake mechanic that doesn't understand how brakes work? I sure as hell wouldn't.

Watching these "programmers" out there who don't have a fucking clue how the code they write does what it does, is like watching a grown man walk around with a kid's toolbox full or plastic toys calling himself a mechanic. (I like cars, ok?!)

*sigh*

Python, AngularJS, Bootstrap, etc. They're all tools and they have their merits. But god fucking dammit, they're not the ONLY damn tools that matter. Stop making excuses *not* to learn something, Mr."IOnlyDoFrontEnd".

Coding ain't Lego's, fuckers.

!rant

I built my first android app, it sends TCP packets to my computer

neat

Not mine, but thought it was funny

First lecture of computer networks. Let's shove all of these abbreviations with their meaning, and possibly a associated port number in one 1.5 hour lecture:

HTTP, HTTPS, FTP, FTPS, SFTP, TCP, IP, UDP, ISP, DSL, DNS, LAN, WLAN, WDM, P2P, TELNET, PGP, TLS, SSL, SSH, MIME, SMTP, POP3, IMAP, IANA, DHT, RTT, DHCP

I really feel sorry for students who didn't have previous knowledge about this stuff..

FUCK LINUX

now that I have your attention, and you’re probably angry, too, please, even if you don’t read this rant, never use code.org again. now, onto the rant…

god dammit, code.org sucks. I mean, anyone who created it or associates with it should, well, be considered a terrorist. they’re bombing students futures in computer science with false, useless, bullshit information. not to mention, their sponsors like bill gates, mark zuckerburg, and other rich asses, talk in a video about some boring ass shit that is hard to understand for anyone who doesn’t program, and not to mention, they use a fucking five dollar microphone. ear rape. even if you look at a textual version of it, then read the information on it, it’s practically useless because it's so terribly explained, and also useless. ironically enough, they focus on their animations more than their actual explinations, or their students for that matter. the fact that we had to encode a picture in binary, made me about 50% dumber, give or take a 0 or 1. then, we had to do it in hex, which wasn’t really much better, although more realistic I supposed. what's really the most depressing thing about this class is its application in the real world. I've learnt nothing whatsoever that will help me in the real world, or in computer science. I suppose there's two things that may be useful (that I already knew): hex, and that TCP doesn't lose packets. that's it. those two things. five seconds worth of knowledge from the first quarter of the year. the ideas just make me want to throw up. teaching the main ideas of computer science without actually teaching it? one of the teachers (probably a good one) enrolled her students in an online programming course just so they could understand, because the explanations are just so terrible. this is the only [high school] computer science course offered by code.org, and I signed up because it's an AP computer science class (tried to get into AP Java, the day I was supposed to take the test to get into an upper level class, I was told it didn't count as a tech credit). seriously, fuck code.org. it makes you dumber. their 'app lab' environment is pointless, just like everything else. the app lab is basically where you have a set of commands and have to make a dog bark() or a storm trooper miss() [and that's hell when they haven't introduced while loops yet]. the app lab is literally code.org going out of their way to make everything that their students are learning pointless in the real world. seriously, why can't we just use a <canvas> like an ACTUAL PROGRAMMER would do if they were to make a browser game, not use an app engine so slow it would be faster to update windows and android studio each time I run an 'app' in their 'environment'. their excuse is that the skills "transfer over" to the real world. BITCH! IF I DIDN'T KNOW JAVA, AND I WANTED TO MAKE A GAME IN JAVA, I'M NOT GOING TO LEARN PYTHON, THEN "TRANSFER" THE SKILLS I LEARNT, I'M GOING TO LEARN FUCKING JAVA. AND THAT GOES FOR EVER OTHER LANGUAGE, PROJECT, ETC.

I'm begging you code.org, stop, get help.

TCP vs UDP...

My tablet is lying on a table 2m away from me and I have to install a new app.. but I don't want to get out of my couch ffs! And I haven't configured dropbear in it yet, and neither do I have adb over TCP/IP. Well fuck it then. My desktop with BlueStacks.. hah, it's running fucking WanBLowS. No remote access there. Too much to ask of that certified pile of crap.

But the point is.. moar remotes, moar better 😋 anything to not have to stand up, taught by my ability to log into a server in Italy from the comfort of my couch. SSH and the sysadmin trade sure is nothing short of amazing ♥️

Wanna to hear some TCP joke?
Yes.
Connection timed out.

Anyone else's blood boil when TV shows abuse tech terminology? Like the 'hacker' saying "connecting the virtual TCP to the neural net."

My grandmother started dating soon after granddad's death.
Death of Grandpa: fuser -k 80/tcp
Announcement to all programs, port 80 is now free

I wonder whether this is a bug in Chrome, or if it's just Google drawing the conclusion from my northern geo-position, that we still haven't left the stage of building longships, raiding England and Scotland, burning monasteries and writing awesome poetry and literature in weird characters sets.

Well, I'm not Ragnarr f*cking Loðbrók or Egill Skallagrímsson, so I can't read electronic component data sheets the way those guys did.

I'll go grab my chisel, so I can carve a bug report into a suitably flat stone and shove it down the TCP/IP series of tubes leading to Google.

That's how it all started ..

As we're all going about our various Easter, Passover, et al., family celebrations, I have the perfect solution to help train your families to stop asking you for help with mundane computer stuff:
Every time someone asks you to do/fix something, give them a full talk about what is going on in their computer around that system.
Don't forget you can talk about lots of things too:
- concurrency
- TCP IP / socket networking
- multi-threaded programs vs. single threads
- RISC vs. CISC processors
- Why linux is better than Windows or Mac
- algorithms
- logarithmic runtime
- teach them how to convert between hex, binary, and base ten
Really pour it on too. Soon they'll either figure out that you are a highly-skilled individual who is not their personal geek squad, or they'll be too afraid of a big lecture to ask for help.
Works with my in-laws like a charm.

What does the year 2030 have in store for us?😂

I wrote an application to demo at a convention coming up. Which feeds tcp data from arduino devices to real time d3 maps via websockets.

Demoing today, and the owner starts talking about a project he saw that which lit up some lights to a device in the room via the internet. In this same meeting he casually mentions he wish he had developers who could do that type of stuff.

The disconnect is massive and soul breaking.

Was forced to do some work on Windows this week (CAD tools that runs only on Windows). I spent a few days just setting up the tools. There were quite a few things I realized I forgot about Windows (as compared to Linux).

1) Installation times are down right horrific. What exactly are the installer doing for 10 minutes?
2) .NET is a cluster fuck. Not even Microsofts repair tool can fix it, but rather just hangs. I ended up using another tool to nuke it and reinstall.
3) Windows binary installs are insanely huge, thus, takes forever to download.
4) The registry is a pointless database that must have been written in hell with the single intent of destroying users will to live. The sole existence of the registry is another proof that completely incompetent engineers designed Windows.
5) Rebooting is the only way to solve many problems. This is another sure sign of a fundamentally fucked up OS design.
6) What the heck is wrong with the GUIs designers? The control panel must be the worst design ever. There are so many levels to get to a particular setting I'm getting dizzy. Nothing gets better by the illogical organisation.
7) Windows networking. A perversion of the tcp/ip stack that makes it virtually impossible to understand a damn thing about the current network configuration. There are at least 3 different places that effects the settings.
8) Windows command prompt. Why did they even bother to leave it in? The interpreter is as intelligent as retarded donut. You can't do anything with it, except typing "exit" and Google for another solution.
8) Updates. Why does it takes hundreds of updates per month to keep that thing safe?
9) Despite all updates that is flying out of Redmond like confetti, it is still necessary to install antivirus to keep the damn thing safe. That cost extra money, and further cost you by degrading performance of your hardware.
10) Window performance. Software runs like it was swimming in molasses. The final stab in the back on your hardware investment, and pretty much sends performance on your hardware back a few hundred bucks more.
11) Closed source is evil. If something crash consistently, you might find a forum that address the issues you have. Otherwise you're out of luck. On the other hand, it might be for the better. I imagine reading the code for Windows can lead to severe depression.

I'm lucky to be a Linux dev, and should probably not complain too much... But really, Windows, go get yourself hit by a truck and die. I won't miss you.

When my first TCP program made contact with another computer.
That was glorious!

Wanna hear a TCP Joke? 😝

Network Security at it's best at my school.
So firstly our school has only one wifi AP in the whole building and you can only access Internet from there or their PCs which have just like the AP restricted internet with mc afee Webgateway even though they didn't even restrict shuting down computers remotely with shutdown -i.
The next stupid thing is cmd is disabled but powershell isn't and you can execute cmd commands with batch files.
But back to internet access: the proxy with Mcafee is permanently added in these PCs and you don't havs admin rights to change them.
Although this can be bypassed by basically everone because everyone knows one or two teacher accounts, its still restricted right.
So I thought I could try to get around. My first first few tries failed until I found out that they apparently have a mac adress wthitelist for their lan.
Then I just copied a mac adress of one of their ARM terminals pc and set up a raspberry pi with a mac change at startup.
Finally I got an Ip with normal DHCP and internet but port 80 was blocked in contrast to others like 443. So I set up an tcp openvpn server on port 443 elsewhere on a server to mimic ssl traffic.
Then I set up my raspberry pi to change mac, connect to this vpn at startup and provide a wifi ap with an own ip address range and internet over vpn.
As a little extra feature I also added a script for it to act as Spotify connect speaker.
So basically I now have a raspberry pi which I can plugin into power and Ethernet and an aux cable of the always-on-speakers in every room.
My own portable 10mbit/s unrestricted AP with spotify connect speaker.
Last but not least I learnt very many things about networks, vpns and so on while exploiting my schools security as a 16 year old.

Just talked to a guy who codes microcontrolers in assembler. He wants to use a raspberry pi as an interface device between TCP and Serial port. He asked me how fast that would run over internet and I told him that it depends on the connection an other things it takes at least some milli secs to transmit.
He is like:
What the fuck do you mean milli secs?
I poll data on my 20 mhz controler every like micro sec or so and that Pi got 1Ghz.

Me like: Yea go fucking code that shit on your own with ASM.

I was promised a three way and all I got was a TCP handshake. 😂

Would you like to hear a TCP joke?

This evening for curiosity i executed a nmap over my android phone expecting (like everyday) all port closed.
But i see
9080/tcp open glrpc
Wtf??
Let me check something....
--adb shell
$cat /etc/net/tcp

And the first line provied me the UID of the app that was running on 9080 port (2378 in hex)
So let me check which app is that
$dumpsys package | grep -A1 "userId=*UID*"

And the answer is com.netflix.mediaclient

Wtf??
Why netflix is running a http server on 9080/tcp on and android phone??

My school blocks all UDP traffic going outside their network. 1 - 65535. Which in turn means that I had to switch to TCP for my VPN to connect. Now my VPN is slow as shit. -.-

This morning... Five hours of theoretical lesson of informatics, systems and networks!! :)
Let's Go! 💪

CS Teacher today:
"Transport Layer provides Security and Encryption to the communication" (TCP/IP stack)

me: WTF? Encryption is provided on the *top* of the transport layer (aka Application) ( and below [Network Layer] there is IPsec)

Teacher: no, it's wrong.

me: so Wikipedia it's wrong, RFC 5246 is wrong, and you have right?

Teacher: Yes.

me: Ok. (aka fuck you!)

All sysadmins, PLEASE! For the love of God just block port 21 in any direction from anywhere, going anywhere.. FTP needs to die.. The f**king protocol predates tcp/ip for God's sake! We need to stop project managers using it, it's a nightmare!!

IoT device endpoint: public fixed IP, raw TCP socket, no auth at all

Ok, first rant, about my struggles getting reliable internet over the past 6 years. It's not too interesting of a topic, but here we go:

I'm living in a more rural part of Germany and internet here is shit. I pay more than 50 bucks a month for 700kb/s downstream (let's just not talk about upstream...), which is meh by itself but it gets worse. Before this I had roughly 230kb/s downstream using DSL. My provider came out with a new oh-so-fucking-fancy solution for giving people faster internet without upgrading their lame ass fucking backbone and POS infrastructure from 70 years ago: they sell you hybrid internet which combines your shit DSL and an LTE connection using TCP Multicast. Not only do I get only 6 of my promised (and payed for) 50 Mbit, no, It's also a fucking piece of nonworking shit!!!

Let me illustrate:
You constantly have problems with web content (or any remote content) not loading because the host server does not support TCP Multicast. It either refuses connection altogether or it takes about 30-50 seconds to establish a connection. Think about your live when it takes two or three fucking minutes to load 5 YouTube thumbnails or load new tweets at the bottom of the Twitter page! Also, you never know if you a) have an error in your implementation of a new API or if b) the remote host doesn't support TCPMC (there's never an error for that! Fuck you!), your SSH sessions ALWAYS drop in the most inopportune fucking moments because the LTE thing lost connection, you always have to turn on a VPN if you want to visit specific websites (for example your school's website) and so on....

Oh and also, my provider started throttling specific services again these days with Netflix and YouTube struggling to display 240p, fucking 240p video without buffering when I get 600kbit down on steam (ofc the steam download is paused when watching videos). When using a VPN, YouTube 720p and Netflix HD work like a charm again. Fucking Telekom bastards

Then there is the problem with VPNs. The good thing about them is that they solve all the TCP Multicast problems. Yay. Now for the bad things:
First of all, as soon as I use a VPN, access times to remote go up by like fucking 500%. A fucking DNS lookup takes 8-15 seconds!!! The bandwidth is there but it takes forever.. because reasons I guess. Then the speed drops to DSL speeds after a while because the router turns off my LTE connection when it is unused and it does not detect VPN traffic as traffic (again because... Reasons?) And also, the VPN just dies after an hour and you have to manually reconnect (with every VPN provider so far)

And as if that wasn't enough, now the lan is dying on me, too, with the router (the fucking expensive hybrid piece of shit, 230 bucks..) not providing DHCP service anymore or completely refusing all wifi connections or randomly dropping 5Ghz devices, or.....

You get the point.

The worst thing is, they recently layed down 400mbit fiber in my neighborhood. Guess where the FUCKING PIECE OF SHIT CABLE ENDS??? YEAH, RIGHT IN FRONT OF MY NEIGHBORS HOUSE. STREET NUMBER 19 IS SERVED WITH 400MBIT AND MY HOME, THE 20, IS NOT IN THEIR FUCKING SERVICE REGION. Even though there is a fucking cable with the cable companies name on it on my property, even leading up to my house! They still refuse to acknowledge it! FUCK YOU!!!!

Well anyways thanks for reading. Any of you got the same problems? :/

4 and a half years doing socket/network programming and I only just learnt my understanding of TCP was largely incorrect...

Well then... That's something...

UDP joke, I don't care if you get it.

So client wants an android app that implements some legacy Epson printer SDK, works on a chinese Windows device with an android Emulator on it, connects to local Webservice that had to be configurated and ran (local Network) , sends and tracks data, if Server down then handle it on the Client and reconnect as soon as Server up, running own TCP Server on Android device that listens for specific http requests, which make the android connect to an Epson printer to start printing. The stuff that is being printed? A png file that has to be converted to a Bitmap, a QR Code that has to be generated by the bugged base64 encrypted stuff coming via http in (webserver-> Android TCP server)
Dont forget the Software Design (MVP), documentation, research etc.. Im about to finish the app , its my 5th day on this Project, the 6th day was planned to be full testing. Client Calls me and ask me how far I am, I reply, he says ok. 30 minutes later he tells me he wont pay me next time that much because this work should take 3 days, or even 2. "A senior Android developer could do this in 2 days"... When i sent him my notices he called me a liar, his webdev has alot of experience and told him it should take 2-3 days...ffs

!rant seems that my raspberry pi serial idea is a little bit complex at the moment and may take a more serious turn later, but I have studied and found DOS based TCP/IP software that will allow me to use my 5150 with actual Ethernet. There are a few 8bit ISA Ethernet cards that will work in the 5150 and separate executables that will configure DHCP, DNS, and even allow me to use a terminal emulator and SSH to connect to *nix based computers over lan! I'll keep you all posted!

When some other team wants to blame us because they're getting a HTTP Status Code 0....

That's not even a valid status... IT MEANS YOU ABORTED THE REQUEST AND KILLED THE CONNECTION...

OH STILL OUR FAULT... WELL DO U KNOW ABOUT NETWORK ISSUES AND SERVER OVERLOADING WHEN U SPAM IT WITH TOO MANY REQUESTS?

OH YOU RETRIED? HOW DID YOU RETRY? BETTER NOT BE SPAMMING US WITH MORE REQUESTS...

EVER HEARD OF TCP/IP BACK OFF LOGIC....

I do some robotics stuff on the side. We built our robot around a Raspberry Pi last year. We had 2 Python scripts talking over TCP, one for the bot, one for the controller. Overflowed the buffer on the bot and it went berserk once the script crashed.

Old Days

Isn't Perl a beutiful language? Just check the beutiful screenshot of a function I just written...

Also this is so beutiful. Did you know that you can actually print directly from a perl script?:
$qp = new PostScript::Simple(papersize => "A4",direction => "RightDown",coordorigin => "LeftTop", colour => 0, eps => 0, units => "pt");
$qp->newpage;
$qp->setfont("Courier", 20);
$qp->text(20,20,"Hello Devrant");
$psock = IO::Socket::INET->new(PeerAddr => "192.168.1.40", PeerPort => "9100", Proto => "tcp");
if ($psock) {
$psock->autoflush(1);
print $psock $qp->get();
close($psock);
}

Ok... Now the fun stuff can begin :)

Tcp vs Udp

All good things come in small packages. Some TCP and some others IP.

Here's something I'm sick of seeing: server software documentation that doesn't fully list what ports they are using. Too often I've read things like this: "AcmeServe uses ports 400, 8001, and 8002". Great, but why are you making me guess if those are TCP or UDP?

And sometimes it's: "AcmeServe uses ports 400 (UDP), 8001 (TCP), and 8002 (TCP)". Soooo, which ones do I port forward? Are you really going to make me have to use netstat -a to find out?

I can't understand the mentality behind that. They obviously realise you need to setup firewalls, but they half-arse it by only telling you the port numbers but not the protocol and/or if they're inbound/outbound.

Please, list what protocol the port is and if it's listening or outbound. Oh, and consider also mentioning where the port numbers come from in your config files, so I don't have to go playing a guessing game with a bunch of XML files should someone have overridden the default port numbers.

It must be good to at least know computer networking?! I remember nothing about these TCP, UDP, whatever the fudge protocol shite. I don't remember these megabit and megabyte things. All I do is code from one end to another. Anyone else watched Eli The Computer Guy's series?

Some of my colleagues are dumb as fuck! I changed the text on a button and now they are not able to work with the program anymore! i wish i could implement "headnut over TCP/IP"... BAM, BAM!!!

Since my ISP doesn't allow port forwards on that port, does anyone want to open their port 445 (if not otherwise occupied by Microsoft-DS) and have netcat reply an empty string or so any request (such as an empty string) sent over TCP (or has anyone already done so)? It would help me out a lot with testing out some networks full port range (since portquiz.net's hoster blocks that port) and would take close to no bandwidth for you.

I know it's been said in a comic before but..

The power to punch people over standard TCP/IP

I just had to join in on this. First post. Hi everyone :>

I saw this today. That's one way of ensuring that you take the medicine

TCP Keepalive. That's all, keep me alive.

so remember how I said I was sending TCP packets? screw that

UDP is life

I never studied CS. This was probably around 2004 (I was 10), I just got my first own computer. I used to mess around with HTML and JS previously, like making obnoxious marquees and so forth, but then I met this guy on DC++ who taught me the basics of VB. Before that I'd always thought of people who could make compiled exes as magicians, and I suddenly became one of them. It was a very empowering moment. While others were playing, I coded apps such as a geometry calculator for school, a TCP chat program (not as cool as Zuckerberg's), and so on.

Ancestors of TCP 😂

For the few mullvad VPN users here: is it possible to use tcp instead of udp?

The most crazy issue I've fixed was caused by a TCP behavior which I didn't know, called the "half-closed connection".
There was a third-party application installed on a production server which called a LDAP server for retrieving users information. During the day we had several users using the application and all worked fine. During the night, when the application was not accessed, something happened and the first call to the application in the morning was stuck for about 5 minutes before returning a response. I tried to reproduce the issue in a testing environment without success. Then I discovered that the application and the LDAP server were located on two different networks, with a firewall between them. And firewalls sometimes drop old connections. For this reason network applications usually implement a keep-alive mechanism. Well, the default LDAP Java libraries don't set the keep-alive on their connections. So, I found a library called "libdontdie", which force the keep-alive on the connections. I installed the library on the server, loaded it at the startup and the weird stuck behavior in the morning disappeared.

Automate this!

I'm an aspiring coder working some chappy administrator job just to pay the bills for now. My boss found out that I may actually be more computer literate than I let on.

Boss: "I want you to make X happen automatically if I click here on this spreadsheet"

Me "X!? That means processing data from 4 different spreadsheets that aren't consistently named and scraping comparison info from the fronted of the Web cms we're using"

Boss: "if you say so.. Can you do it?"

Me: "maybe.. Can I install python?"

Boss: "No..."

Me: "what about node.js or ruby?"

Boss: "no.. I don't know what you're talking about but you're not installing anything, just get it done"

Me: "Errm Ok.."

So here I am now, way over my head loving the fact that I'm unofficially a Dev and coding my first something in Powershell and vb that will be used in business :)

Sucks that I still have to keep my regular work on target whilst doing this though!

Today I have created a server application on Python Tornado which can forward TCP Packets directly to HTTP request queue without any intermediate caching.

Our remote IOT devices (microcontrollers with sensors attached) send sensor reading over TCP Socket to our server and all the connected web applications can show the data instantly using long polling and the above mentioned technique.

Is there a better way communicating between php and java than tcp? Because this was my first idea but i try everything on localhost and the request takes up to 3 seconds...

That moment when full-stack web development suddenly includes troubleshooting the TCP connections on your new listener.

#rememberthatoneclassinundergrad

Keep going into application level timeouts and insufficient number of xml messages frames transmitted through tcp sockets.

Found that a "custom" C-written xml parser needs 10 seconds to find the core data within 2500 chars of that xml.

I knew that C is blazing fast but that's until it's used by some dick head.

Since tcp sockets cannot have custom headers and cannot contain post request values, is a vpn tunnel the only real secure way to set up websocket connections for 3rd party connections to my API ?

I know this is not StackOverflow but is there a way to send TCP packets using JavaScript? I can't find a pretty solution. Why I can't find an API like "sockets" from Python to JavaScript?
Telnet API will be fine too.

Thanks!

The beginning of the TCP/IP

Perfect! (Copyright : some Facebook page)

Tl;dr:
My stupid ass needs a break, also a good english lesson, sry for grammar errors.

# rant.start()
You may want to ask how it is to be kind of stressed. I'll tell ya.
I'm half way through my semester and all of my profs had the same idea: projects. Huge ass projects for everyone with the smallest possible time to finish them. Also i'm moving in a new flat in a few weeks. Shove your projects up your fucking bleached arsehole and put a huge cork right beneath it.
I started to wonder why my stupid tkinter application started freezing after implemeting a thread for a small tcp module.
Confusion.
Frustration.
Hate.
Chaos.
Crying for help.
Zergrush on SO.
Realizing i used thread.run() instead of thread.start() .
Fml, i need a summer break.

I have to take UDP and add packet ordering, filter in, and resend and some form of handshake, because client couldn't figure out how to change the port from UDP to TCP and refused any help

Made a root only app: enable/disable GPS, mobile data, airplane mode and etc. work on not rooted device(yes all these functions work too).

How: Desktop app which downloads cross-platform ADB drivers, unzips them, executes a few commands, deletes the drivers and voala.
P.S: I use local ADB TCP connection(yeah I ported a part of the drivers for java android) and write_secure_settings granted with 'pm grant'.
And everything is user-friendly with screenshots explaining how to enable ADB and how to click a 2 buttons.

I've always heard that developers and well engineers in general tend to have some unique dreams in times where their work presses them to limits. Sometimes it's stacking hypothetical boxes in specific orders or plugging and unplugging things. Well I've been playing with some complex tcp server concepts and theories lately and started running a really bad fever last night. My whole night consisted of falling asleep, consistently connecting websocket servers to clients, getting socket hang up errors from which I'd then wake up in cold sweat and fall back asleep only to find myself debugging again. My bosses response was f*** man take a vacation 😂😂, drink more, but ya we need this done in 2 weeks

Please God let someone finally implement TCP/IP over punchcard with mechanical routers.

We had C project in school about multi-process communication and syscalls. We worked in groups of three.
I made a "framework"(header file) with important prototypes and definitions of needed variable sizes.
One of group member decided to null his variable by bzero syscall (writes null bytes). He ignored my framework and typed literal "sizeof". Ofc nulled double the needed value and it nulled another variable with some TCP packet also.
Spend week trying to find what is wrong with it.
I hate group projects.

I don't know if many rememeber me but at one point this year I had to turn UDP basically into tcp, handshake, packet ordering, resend on failed, ACK response, and 4k bit aes encryption. Fucking done, it works, signed the last version and pushed to client, client loved it, just what he wanted, paid out contract then turned around and asked me to setup his server for one day with no further expectations and an extra 250, said sure don't mind, as I am setting shit up I decided to test if his business isp really blocks tcp, guess what? NOPE IT WORKS JUSY FUXKIJG FINE AND I COILD HAVE KUST RIPPED A PREMADE CORE AND GOT PAID AND SET IT UP AND HE WOULD NEVER know, but maybe theirs some weird circumstances that require the core to be made only with udp, so after I was done I asked why only udp if his line allowed tcp? Requirements maybe? NOPE HE JUST DOSENT UNDERSTAND TCP FUUUUUUUQQQQHDJDIOAJEJDICJDNXIKZMZJDJCU

Just wanted to do some scripted image resizing for school in school because the teacher asked me to help her with that.
So I thought: Let's just write a tiny script. Written the script in almost no time (just iterates over all jpg's and resizes them)

30sec.

Now I tried to run it. Didn't have my laptop so I had to somehow run it on their windows PCs. At least it's windows 10, unlike other schools that still run XP and stuff so I thought it might be doable. Well guess what, nope it wasn't.

First tried to install imagemagick, that didn't work as only teacher accounts have admin and the teacher was already pretty scarred once he saw me doing stuff in powershell so I thought I'd better not ask to do this via a teacher account and mess with stuff as admin.

Next method: Installing msys2. That worked at least (after taking forever to install and having to mess with the av software to get it to run).
And there comes the next problem: pacman doesn't connect via the proxy so I can't download any packages. There is free wifi but only for teachers, and students aren't going to get access until the school finally has a faster connection because they'd (understandably) cause this connection to be constantly overloaded. I just happen to have access to this wifi network, too, because at least the guys from the IT dept know how bad using proxies under linux is. So I connect via wifi and it works. At least I thought: After running the script it yields weird errors about unsupported arguments even though the command is exactly the same I have been using for years (already checked typos twice)

Then got the idea of simply installing imagemagick on termux on android and transferring the files onto my phone.
Too bad we aren't allowed to attach our own USBs to the pcs. Luckily I got a rooted phone so I simply activate adb over network and connect to it.
After downloading the platform-tools I can't run them because of AV software. Luckily there is an option to add an exception per executable so I do that. After doing that it works.... nope it doesn't. The wifi only allows 443/tcp and 80/tcp, even for internal network devices.

So that's it. I'm simply going to upload that stuff to my nextcloud and convert it at home.

Windows, I hate you!!!

I’ve got a really good TCP/UDP joke to tell you, but I don’t know if you’ll get it

I want to start learning to write a simple game server emulator in C#. The game works LAN but it gets LAN disconnected when internet drops so some sort of keepalive is implemented. I can copy the files to another device and it works online without a login etc so there is no online authentication but as soon as internet drops the LAN game goes down to so i need to emulate the online update server or something like that to prevent that from happening. (spotted with Wireshark etc)

I don't have much experience , just created a simple tcp client/server console app but in this case I ofcrs will only need a server one in combination with custom dns. Any tips on where to start? Does someone have an example game server emulator? or update server emulator?

Just these little things that can drive you insane: TCP should guarantee that the order of packages is preserved, but somehow through a splitting of the message I get them files mangled. OK, might be our own fault, but then I just do a simple grep on the log file, but it won't display anything if I escape the f** dot.
Google it. No I didn't do it wrong, try different quotes. Nothing. Why then does it display the thing if I delete the dot?
Beginning to question my sanity. Grep just. has. to. work.
And that very moment the blinds of the window automatically go up, so the blazing sun blinds us, which as management told us, is not a bug but a feature, protection from freezing bla bla - and the control of the blinds gives me static shocks but refuses to shut them down again.. *sigh*
Just these little things. - Don't know, but I am convinced at the right time, a little mispunctuation or a glitch in a UI could drive a programmer mad.

Fuck you sophos. Fuck you hard. I moved a server to a new datacenter and it worked like a charm. Thank you windows and hyper-v. BUT! BUUUUUUT my fucking sophos worked like shit. Blocking everything by default? Yeah fuck you. Reconfigured everything. Still blocked and why? Forward “all“ doesnt mean forward all. Had to apply rules from port tcp 1 - 65335 and udp 1-65335. Nice you piece of fuck.

Can some1 explain me this in detail, please? c:
