After over 20 years as a Software Engineer, Architect, and Manager, I want to pass along some unsolicited advice to junior developers either because I grew through it, or I've had to deal with developers who behaved poorly:
1) Your ego will hurt you FAR more than your junior coding skills. Nobody expects you to be the best early in your career, so don't act like you are.
2) Working independently is a must. It's okay to ask questions, but ask sparingly. Remember, mid and senior level guys need to focus just as much as you do, so before interrupting them, exhaust your resources (Google, Stack Overflow, books, etc..)
3) Working code != good code. You are an author. Write your code so that it can be read. Accept criticism that may seem trivial such as renaming a variable or method. If someone is suggesting it, it's because they didn't know what it did without further investigation.
4) Ask for peer reviews and LISTEN to the critique. Even after 20+ years, I send my code to more junior developers and often get good corrections sent back. (remember the ego thing from tip #1?) Even if they have no critiques for me, sometimes they will see a technique I used and learn from that. Peer reviews are win-win-win.
5) When in doubt, do NOT BS your way out. Refer to someone who knows, or offer to get back to them. Often times, persons other than engineers will take what you said as gospel. If that later turns out to be wrong, a bunch of people will have to get involved to clean up the expectations.
6) Slow down in order to speed up. Always start a task by thinking about the very high level use cases, then slowly work through your logic to achieve that. Rushing to complete, even for senior engineers, usually means less-than-ideal code that somebody will have to maintain.
7) Write documentation, always! Even if your company doesn't take documentation seriously, other engineers will remember how well documented your code is, and they will appreciate you for it/think of you next time that sweet job opens up.
8) Good code is important, but good impressions are better. I have code that is the most embarrassing crap ever still in production to this day. People don't think of me as "that shitty developer who wrote that ugly ass code that one time a decade ago," They think of me as "that developer who was fun to work with and busted his ass." Because of that, I've never been unemployed for more than a day. It's critical to have a good network and good references.
9) Don't shy away from the unknown. It's easy to hope somebody else picks up that task that you don't understand, but you wont learn it if they do. The daunting, unknown tasks are the most rewarding to complete (and trust me, other devs will notice.)
10) Learning is up to you. I can't tell you the number of engineers I passed on hiring because their answer to what they know about PHP7 was: "Nothing. I haven't learned it yet because my current company is still using PHP5." This is YOUR craft. It's not up to your employer to keep you relevant in the job market, it's up to YOU. You don't always need to be a pro at the latest and greatest, but at least read the changelog. Stay abreast of current technology, security threats, etc...
These are just a few quick tips from my experience. Others may chime in with theirs, and some may dispute mine. I wish you all fruitful careers!198
One comment from @Fast-Nop made me remember something I had promised myself not to. Specifically the USB thing.
So there I was, Lieutenant Jr at a warship (not the one my previous rants refer to), my main duties as navigation officer, and secondary (and unofficial) tech support and all-around "computer guy".
Those of you who don't know what horrors this demonic brand pertains to, I envy you. But I digress. In the ship, we had Ethernet cabling and switches, but no DHCP, no server, not a thing. My proposition was shot down by the CO within 2 minutes. Yet, we had a curious "network". As my fellow... colleagues had invented, we had something akin to token ring, but instead of tokens, we had low-rank personnel running around with USB sticks, and as for "rings", well, anyone could snatch up a USB-carrier and load his data and instructions to the "token". What on earth could go wrong with that system?
We got 1 USB infected with a malware from a nearby ship - I still don't know how. Said malware did the following observable actions(yes, I did some malware analysis - As I said before, I am not paid enough):
- Move the contents on any writeable media to a folder with empty (or space) name on that medium. Windows didn't show that folder, so it became "invisible" - linux/mac showed it just fine
- It created a shortcut on the root folder of said medium, right to the malware. Executing the shortcut executed the malware and opened a new window with the "hidden" folder.
Childishly simple, right? If only you knew. If only you knew the horrors, the loss of faith in humanity (which is really bad when you have access to munitions, explosives and heavy weaponry).
People executed the malware ON PURPOSE. Some actually DISABLED their AV to "access their files". I ran amok for an entire WEEK to try to keep this contained. But... I underestimated the USB-token-ring-whatever protocol's speed and the strength of a user's stupidity. PCs that I cleaned got infected AGAIN within HOURS.
I had to address the CO to order total shutdown, USB and PC turnover to me. I spent the most fun weekend cleaning 20-30 PCs and 9 USBs. What fun!
What fun, morons. Now I'll have nightmares of those days again.9
Never in my life I was scared as today.
I recently left a big company to work for a small one as the first internal developer.
Had a small issue in the production server. The fix was easy, just remove a single table entry. And... *drum roll*... I forgot to add a where clause. All orders were lost.
No idea if we had backups or anything, I quickly called the one other IT dude in the company.
He had no clue where are the backups and how to find them.
Having some experience with Nmap, I quickly scanned our network and found a Nas device.
There was a backup, whole VHD backup. 300GB of it, the download speed is around 512kb/s. No way I can fix it before management finds out, but then an idea came to mind. Old glorious 7zip. Managed to extract only the database files, sent them to the server and quickly swapped them. Everything was fine... The manager connected 5 minutes later. Scariest 45 minutes of my life...20
Sooooo me and the lead dev got placed in the wrong job classification at work.
Without sounding too mean, we are placed under the same descriptor and pay scale reserved for secretaries, janitors and the people that do maintenance at work(we work for a college as developers) whilst our cowormer who manages the cms got the correct classification.
The manager went apeshit because the guidelines state that:
Making software products
Administration of dbs
Server maintenance and troubleshooting
And a lot of shit is covered on the exemption list and it is things that we do by a wide fucking margin. The classification would technically prohibit us from developing software and the whole it dptmnt went apeshit over it since he(lead developer) refuses (rightfully so) to touch anything and do basically nothing other than generate reports.
Its a fun situation. While we both got a substantial raise in salary(go figure) we also got demoted at the same time.
There is a department in IT which deals with the databases for other major applications, their title is "programmers" yet for some reason me and the lead end up writing all the sql code that they ever need. They make waaaaay more money than me and the lead do, even in the correct classification.
Resolution: manager is working with the head of the department to correct this blasphemy WHILE asking for a higher pay than even the "programmers"
I love this woman. She has balls man. When the president of the school paraded around the office asking for an update on a high priority app she said that I am being gracious enough to work on it even though i am not supposed to. The fucking prick asked if i could speed it up to where she said that most of my work I do it on my off time, which by law is now something that I cannot do for the school and that she does not expect any of her devs to do jack shit unless shit gets fixed quick. With the correct pay.
Naturally, the president did not like such predicament and thus urged the HR department(which is globally hated now since they fucked up everyone's classification) to fix it.
Dunno if I will get above the pay that she requested. But seeing that royal ammount of LADY BALLS really means something to me. Which is why i would not trade that woman for a job at any of my dream workplaces.
Meanwhile, the level of stress placed my 12 years of service diabetic lead dev at the hospital. Fuck the hr department for real, fuck the vps of the school that fucked this up royally and fuck people in this city in general. I really care for my team, and the lead dev is one of my best friends and a good developer, this shit will not fucking go unnoticed and the HR department is now in low priority level for the software that we build for them
Still. I am amazed to have a manager that actually looks out for us instead of putting a nice face for the pricks that screwed us over.
I have been working since I was 16, went through the Army, am 27 now and it is the first time that I have seen such manager.
She can't read this, but she knows how much I appreciate her.3
Got laid off on Friday because of a workforce reduction. When I was in the office with my boss, someone went into my cubicle and confiscated my laptop. My badge was immediately revoked as was my access to network resources such as email and file storage. I then had to pack up my cubicle, which filled up the entire bed of my pickup truck, with a chaperone from Human Resources looking suspiciously over my shoulder the whole time. They promised to get me a thumb drive of my personal data. This all happens before the Holidays are over. I feel like I was speed-raped by the Flash and am only just now starting to feel less sick to the stomach. I wanted to stay with this company for the long haul, but I guess in the software engineering world, there is no such thing as job security and things are constantly shifting. Anyone have stories/tips to make me feel better? Perhaps how you have gotten through it? 😔😑😐14
Almost a decade ago (damn I'm getting old) I was working on a virtually dead project - i.e. it was the third, and final, iteration of a very failed project in a huge company with literally millions of Euros poured into it.
I came in as a junior SysAdmin/CM to substitute someone who was happily fucking off to another, better job. And alongside me a senior started as well to deal with the management/interaction between vendors and internal "teams" (6 peeps to deal with infrastructure requests from vendors - DBA, SysAdmin, Networking, Hardware commissioning, that sort of stuff).
Now, nothing against this senior - really cool dude - but he was objectively doing a poor management job. Partially due to some personal issues and a little bit of incompetence/disinterest.
So me, and the rest of these peeps that the vendors interacted with, were getting massacred with impossible requests/deadlines and blamed for almost everything wrong with this project.
Two weeks after we started, SeniorMan had to take a week off due to some personal issues so I was asked by higher management to take over his tasks as well until he's back.
The next day, I took all the peeps to get coffee and told them that from now on, regardless of what anyone tells them, unless it's from our direct manager (who pretty much didn't give a shit) every information/decision/deadlines negotiations goes through me and me alone. And they're not allowed to even consider anyone asking them for favours without talking to me first.
Now, this also came with the understanding that I would become the sole person to blame in case of fuck ups, and I gladly accepted because I would have quit anyway if things didn't change.
So everyone agreed.
And oh boy did we put the heat on those fucking vendors, because those two weeks that SeniorMan was busy drinking coffee with the upper management, I studied the entire project - I was familiar with every single network switch, VM, application and most importantly, all the agreements between vendors on which applications they would deliver and when.
They guys from my team also followed through with ignoring vendor requests that didn't come through me. They would literally hang up on them. CCed me on every single email. It was great.
A week later, we learned that SeniorMan would be gone another week, so upper management gave me a company phone because things were going well. SeniorMan would later quit because he pretty much wasn't needed by the time he came back.
With the phone and the blessings of the management I was pretty much the only entry point for vendors to deliver their applications. And I was strict as fuck. My negotiation policy was to multiply everything the peeps from my team told me by 3. If they didn't like it, well tough luck, give us more resources and wait 3 weeks to get them up to speed.
And within a month we became the highest performing team on that project. Outperforming the second best by as much as 6 to 1. All this with much less stress for everyone in the team.
Thanks to these changes, vendors actually had to do their job and deliver the promised services without blaming us. So we magically passed the first milestone, and suddenly went from failed project to the most promising project in the company.
Ah good times, good times...
I participated in a meeting, before hitting the second milestone, where the project lead from one of the vendors was trying to pin their incompetence on us being slow to deliver infrastructure requirements.
So I pulled out the Visio file that everyone in the room agreed to a few months prior, and one by one showed that not only everything was delivered on time but even earlier on some items. And that due to them being slow on testing their shitty software on our infrastructure everything is going to shit.
The CTO of the company was present in this meeting, and what followed can only be described as someone who had no idea what was going on, being hit in the face with some else's balls of steel. This CTO proceeded to yell out how much all the vendor contracts cost and that if these fucks didn't get their shit together he'll release the lawyers from the dungeon of debt.10
Here are the reasons why I don't like IPv6.
Now I'll be honest, I hate IPv6 with all my heart. So I'm not supporting it until inevitably it becomes the de facto standard of the internet. In home networks on the other hand.. huehue...
The main reason why I hate it is because it looks in every way overengineered. Or rather, poorly engineered. IPv4 has 32 bits worth, which translates to about 4 billion addresses. IPv6 on the other hand has 128 bits worth of addresses.. which translates to.. some obscenely huge number that I don't even want to start translating.
That's the problem. It's too big. Anyone who's worked on the internet for any amount of time knows that the internet on this planet will likely not exceed an amount of machines equal to about 1 or 2 extra bits (8.5B and 17.1B respectively). Now of course 33 or 34 bits in total is unwieldy, it doesn't go well with electronics. From 32 you essentially have to go up to 64 straight away. That's why 64-bit processors are.. well, 64 bits. The memory grew larger than the 4GB that a 32-bit processor could support, so that's what happened.
The internet could've grown that way too. Heck it probably could've become 64 bits in total of which 34 are assigned to the internet and the remaining bits are for whatever purposes large IP consumers would like to use the remainder for.
Whoever designed IPv6 however.. nope! Let's give everyone a /64 range, and give them quite literally an IP pool far, FAR larger than the entire current internet. What's the fucking point!?
The IPv6 standard is far larger than it should've been. It should've been 64 bits instead of 128, and it should've been separated differently. What were they thinking? A bazillion colonized planets' internetworks that would join the main internet as well? Yeah that's clearly something that the internet will develop into. The internet which is effectively just a big network that everyone leases and controls a little bit of. Just like a home network but scaled up. Imagine or even just look at the engineering challenges that interplanetary communications present. That is not going to be feasible for connecting multiple planets' internets. You can engineer however you want but you can't engineer around the hard limit of light speed. Besides, are our satellites internet-connected? Well yes but try using one. And those whizz only a couple of km above sea level. The latency involved makes it barely usable. Imagine communicating to the ISS, the moon or Mars. That is not going to happen at an internet scale. Not even close. And those are only the closest celestial objects out there.
So why was IPv6 engineered with hundreds of years of development and likely at least a stage 4 civilization in mind? No idea. Future-proofing or poor engineering? I honestly don't know. But as a stage 0 or maybe stage 1 person, I don't think that I or civilization for that matter is ready for a 128-bit internet. And we aren't even close to needing so many bits.
Going back to 64-bit processors and memory. We've passed 32 bit address width about a decade ago. But even now, we're only at about twice that size on average. We're not even close to saturating 64-bit address width, and that will likely take at least a few hundred years as well. I'd say that's more than sufficient. The internet should've really become a 64-bit internet too.37
Security rant ahead - you have been warned.
It never fails to amuse and irritate me that, despite being in the 2019 supposed information age, people still don't understand or care about their security.
I've travelled to a lot of ports and a lot of countries, but, at EVERY port, without fail, there will be at least one wifi that:
- Has default name/password that has been cracked already (Thomson/SpeedTouch/Netfaster etc)
- Has a phone number as password (reduces crack time to 15-30 mins)
- Someone, to this day, has plain old WEP
I am not talking about cafeteria/store wifi but home networks. WTF people?! I can check my email (through VPN, of course) but it still bugs me. I have relented to try and snoop around the network - I can get carried away, which is bad. Still...
The speed is great though :P9
1996, my colleagues trying to port Chorus microkernel on Cray supercomputer. System crashes every ~5 days with no apparent reason. After weeks of investigation someone notices one of the network cables slightly longer than others ... after ~5 days and speed of light the Cray would miss a clock tick and crashes. Replaced network cable and it works fine!
Don't mess with supercomputers ...2
I die, go to hell and my punishment is to write software for hell network that is having power problems due to light source disruptions and is running on Windows 95 on FAT32 without any service pack.
Network speed is trough 300bps dial up modem. Protocol is over IPX/SPX.
My task is to write interactive websites that are replacement of modern websites but in VBScript, ActiveX, IE 4.0.
I have 10 managers that tell me what to do and scream when I miss deadline that is set everyday without my knowledge at random times.
They send me an email and 5 minutes later they arrive at my desk to ask me about it.
I must work 16 hours a day before I can leave the place and if I won’t show up police beats me and escorts me to the office.
If I’m late a second I don’t get payment.
I can’t afford to rent a place so I sleep in the sleeping bag.
It doesn’t matter much cause as soon as I fall asleep phone rings until I wake up and my manager screams about the problems he have for about an hour.7
RIP servers of https://robinsonsmovieworld.com//
I guess he must've gotten fired. It requests for the system time from the server, gets a response, and then displays it on the page.7
Our internship and placement tests start from 30th and this is message we got from our coordinators.
(We do have WiFi on campus and in labs ,idk why they aren't letting us use that!!)
They are asking use to use the DONGLES ! who the hell has those, these days !
Uni's response to this : if you can't get your own internet source,then don't give the test. (Translation : we don't give a single flying fuck)
Got my self a Jiofi ,I hope it would work fine.
Often our phones catch no network in the labs ! And if they do,the internet speed is slow.
The tests will go GREAT ! 🙃25
Please send help.
My ADSL has been cut off and I am stuck without the internet until Friday, where I will be connected to the NBN(National Broadband Network<fibre>)
To make it worse, previous to my internet being cutoff(without knowledge) I resetted my PC, loseing all IDE. Therefore I can't even work on projects ;(((
I have 500MB of phone data for 2 days. I'm going to have to ration it out to survive. The world is grim and dark. On a side note I do get 10GB of Netflix only data from my carrier, so that's a positive.
For those interested in my new Internet, I was previously getting 12D1U Mbps (Download, upload) with the new roll out of fibre, well kind of. The government cheaped out and did FTTN(Fibre to the Node, like a mini exchange and using VDSL) relying on crappy copper instead of FTTP(Fibre to the premises) basically all fibre. The max theoretical speed is 100D40U, however I am 550 metres of the node and I've guestimated 70D30U but of course I'll have to pay the full price of the connection even though I will most likely get fucked in the end.
I hope you enjoyed reading my blob of random text.14
When I started my current job 6 years ago I was given a desk phone with a 100mb port. Speed didn't matter at the time as everyone was given laptops for our desks. I changed positions in the company where I'm going to be provisioning servers and whatnot over the network. Started using a desktop that didn't have a Wi-Fi adapter. I requested a new phone with a Gig switch port, if possible, so doing file transfers on the network wouldn't be limited. IT had a couple of questions...
IT-Have you noticed slowness when downloading/uploading?
Me-No, but its a 100mb port...so.
IT-Well I just did a speed test and we're getting 60up/5down. Your phone is over that.
(Working from home? Our fiber was way faster than that I thought.)
Me-That's fine, but this will be for internal network transfers. Not going out to the internet. We have gigabit switches on campus correct?
It-Yes but you shouldn't notice a speed difference.
Me, now lost-If you can't change out the phone that's fine. I'll figure our something.
IT-Now now, lets troubleshoot your issue. Can you plug your phone in?
Me-Yes I have it, but I'm remote today. There is no way for it to reach the call manager.
IT-Let's give it a try.
40 min of provisioning later he gave up and said maybe it is broke. Got a "working" one the next week.
PS first post, and writing on phone. Yay insomnia!
Working on some code which relies on a remote api. Then the network speed suddenly drops to 14kbs. FUCKING FUCK FML10
11 months ago I was tasked to audit 58 computer and 6 servers including network speed analysis. In the meeting with the client & stakeholders, they asked my boss how we will achieve this. He replied... "Pen and Paper. We have interns to capture all info into a spreadsheet ". GEEEEEEEZUS!!!4
!rant, but... It’s really nice to live in a country with decent LTE speeds... ;) It’s nice addition to my home 250Mbit DOCSIS connection...17
Microsoft servers just right now were the first servers giving me the full speed my connection can bear.
Downloading a Windows ISO in under a minute with a speed of up to 106MB per second, according to Firefox.
Microsoft, this is a first, but you gave me the biggest grin I had in a while.8
So recently I installed Windows 7 on my thiccpad to get Hyperdimension Neptunia to run (yes 50GB wasted just to run a game)... And boy did I love the experience.
ThinkPads are business hardware, remember that. And it's been booting Debian rock solid since.. pretty much forever. There are no hardware issues here. Just saying.
With that out of the way I flashed Windows 7 Ultimate on a USB stick and attempted to boot it... Oh yay, first hurdle to overcome. It can't boot in UEFI mode. Move on Debian, you too shall boot in BIOS mode now! But okay, whatever right. So I set it to BIOS mode and shuffled Debian's partitions around a bit to be left with 3 partitions where Windows could stick in one more.
Installed, it asks for activation. Now my ThinkPad comes with a Windows 7 Pro license key, so fuck it let's just use that and Windows will be able to disable the features that are only available for Ultimate users, right? How convenient would that be, to have one ISO for all the half a dozen editions that each Windows release has? And have the system just disable (or since we're in the installer anyway, not install them in the first place) features depending on what key you used? Haha no, this is Microsoft! Developers developers developers DEVELOPERS!!! Oh and Zune, if anyone remembers that clusterfuck. Crackhead Microsoft.
But okay whatever, no activation then and I'll just fetch Windows Loader from my webserver afterwards to keygen my way through. Too bad you didn't accept that key Microsoft! Wouldn't that have been nice.
So finally booted into the installed system now, and behold finally we find something nice! Apparently Windows 7 Enterprise and Ultimate offer a native NFS driver. That's awesome! That way I don't have to adjust my file server at all. Just some fuckery with registry keys to get the UID and GID correct, but I'll forgive it for that. It's not exactly "native" to Windows after all. The fact that it even has a built-in driver for it is something I found pretty neat already.
Fast-forward a few hours and it's time to Re Boot.. drivers from Lenovo that required reboots and whatnot. Fire the system back up, and low and behold the network drive doesn't mount anymore. I've read that this is apparently due to Windows (not always but often) mounting the network drive before the network comes up. Absolutely brilliant! Move out shitstaind, have you seen this beauty of an init Mr. Poet?
But fuck it we can mount that manually after every single boot.. you know, convenient like that. C O P E.
With it now manually mounted, let's watch a movie! I've recently seen Pyro's review on The Platform and I absolutely loved it. The movie itself is quite good too. Open the directory on my file server and.. oh. Windows.. you just put db.thumb on it and db.thumb:encryptable. I shit you not, with the colon and everything. I thought that file names couldn't contain colons Windows! I thought that was illegal in NTFS. Why you doing this in NFS mate? And "encryptable", am I already infected with ransomware??? If it wasn't for the fact that that could also be disabled with something as easy as a registry key, I would've thought I contracted ransomware!
Oh and sound to go with that video, let's pair up some Bluetooth headphones with that Bluetooth driver I installed earlier! Except.. haha nope. Apparently you don't get that either.
Right so let's just navigate the system in its Aero glory... Gonna need to flick the mouse for that. Except it's excruciatingly slow, even the fastest speed is slower than what I'm used to on Linux.. and it's jerky as hell (Linux doesn't have any of that at higher speed). But hey it can compensate for that! Except that slows down the mouse even more. And occasionally the mouse driver gets fucked up too. Wanna scroll on Telegram messages in a chat where you're admin? Well fuck you mate, let me select all these messages for you and auto scroll at supersonic speeds! And God forbid that you press delete with that admin access of yours. Oh maybe I'll do it for you, helpful OS I am!
And the most saddening part of it all? I'd argue that Windows 7 is the best operating system that Microsoft ever released. Yeah. That's the best they could come up with. But at least it plays le games!11
fuck wordpress... Got a request to improve wordpress site speed + pagespeed score. 20-30 plugins, 15 or more additional ones off. Improved the score and noticed that my adblocker is blocking a lot of urls. Sure enough theres a hidden iframe in the bottom with 10 ad network scripts and bidding get requests. Someone is making ad revenue from this shit.. wtf. I've only had problems with shitty wordpress sites being hacked for some reason. It's always a shitty experience. Any tips on fixing hacked wordpress sites?5
TIL how time-delay relays are used in circuits with a hell lot of power. For example to power and control the motor of a machine that lifts 20 people up to the sky and back to ground again.
FYI this is a simple circuit. We will hopefully start experimenting with SPS/Speicherprogrammierbare Steuerung (Programmable Logic Controllers). I cannot wait to make use of our predesigned circuits with complex logic gates with the new unit we will get to know.
Unfortunately, we will do practical networking (testing cables for the signal strength and speed, building a network of telephones and call each other - guess this is going to be the funniest part lol, etc.) before the SPS and LOGO software phase.
Btw. I am doing an all-nighter rn and repeating everything we did in our recent signal calculation lesson. We have another exam tomorrow.11
I started a short term contract job that requires access to company online resources. Only problem is the office I'm working in has really bad internet. The connection speed at best is comparable to dial up and at worse just non-existent. I tried tethering to my phone but this wasn't working either due to low signal. I mention this as an issue early on the week to the boss. Later in the week the boss asks how things are going at the same time that the network is down. I tell him the same problem. He then tells me his computer is fast and he has internet, so I show him the 2 computers I have access to and how they are too slow/no internet. He then tells me a bad workman blames his tools and he's not happy with me for having problems.
Don't even know what to say to that. I just told him this role wasn't working for me and clocked out.8
Finally gigabit speed in my new flat... If any of my laptops had more than a 100mbit network card, I'd use it :(6
I hope I did not make the wrong decision here:
Been working on a side project using React Js for a year now. After getting to know more about Vue, I just started rewriting it and moving it to Vue, to speed things up I'm using core JS classes for network stuff and validations ...etc just rewriting Redux to Vuex and React Components to Vue Templates
If I made the wrong decision I'd appreciate if anyone tell me about it before I go deeper in the rewrite process lol
It is not that I found speed difference both perform the same from what I've seen for my scenarios. But the output code of Vue is soooo much cleaner than what I found in React, either I failed to write a clean react code no matter how hard I try to optimize it, or Vue really takes the short way and keeps things clean.19
What I have learned from neutral networks for my life.
It's already a year that I'm familiar with NNs. I did not write anything serious and did not learn it that deep. But, actually, the basic knowledge gave me an interesting view to my life. I just want to share one fact with you.
There is a learning speed in NNs, which specifies how fast does the network learn. If it is too high, any new information will be accepted very easily but will wipe the past of the network's knowledge and if it is too low, the network will hardly accept new info but remember everything. When people born, they learn everything very fast and by the age they become more hard-learners Here, I've learned that you should not live in the past, and not for the current day. You just have to keep the balance.1
Q: How instantaneous are these jobs? *referring to a Jenkins job to upload database from local to an environment
A: Well that depends on your network speed. Here in the middle of nowhere, I have a donkey carries the package up the mountain, so that could take a while.2
Well, wasn't my mom, but once, i was in the house of the nanny of a girl i used to date..
I've told her that Im a developer and The nanny already got it like : "ok you know about cumputer and stuff related"..
So..the internet connection was shitty as fuck
She asked me to repair the internet,
I told her I didn´t know anything about network, but.. she insisted.
I said that she better call their internet company and they would explain what is the situation there..
She told me that It was unnecesary, and insisted again..
(We wera talking in the bedroom)
So i left the bedroom, then I went to fucking internet modem, unplug the power cable, then plugin it again..
The internet was still shitty, BUT, she had a placebo effect about the speed.. she was so happy with me and she started saying that I was smart.. (I wanted to kill myself)

My Windows 10 VM gloriously just shat itself so badly, it's now stuck in a BSOD bootloop (first time ever I managed to get a BSOD in a fucking virtual machine btw) and I need to reinstall it. So I need to download the newest Win10.iso.
But I'm also currently working on a university assignment that requires me to be connected to the university-network via a VPN that's slower than my 90s ADSL connection (~1Mbps) (see my previous rant). So to download the 4.7GB iso it'd take.... I'm bad at maths, so let's just say fucking AGES.
So I spin up another VM with a bridged network to download my Win10.iso with Gigabit speed to set up another VM.... wonders of modern technology
Had to use the pfsense's url in my Default Gateway which is 18.104.22.168 from our school.

Unfortunately the Network Admin found my IP and slowed down my download speed. I can search R-18 links but I don't want to be caught in his SquidProxy log. so I'm still lucky to browse my animu website.3
The year was 2006. During the first half of my career, I use to work in the NOC. This was before I made my transition to software engineer. I worked on the third shift for a bank services company. The company was on a down turn. Just years earlier they just went public, and secured a deal with a huge well known bank. Eventually they entered a really bad contract with the bank and was put into a deal they couldn't deliver on. The partnership collapse and their stock plummeted. The CEO was dismissed, and a new CEO came in who wanted to "clean things up".
Anyway I entered the company about a year after this whole thing went down. The NOC was a good stepping stone for my career. They let me work as many hours as I liked. And I took advantage of it, clocking in 80 hours a week on average. They gave me the nick name "Iron Man".
Things started to turn around for the company when we were able to secure a support contract with a huge bank in the Alabama area. As the NOC we were told to handle the migration and facilitate the onboarding.
The onboarding was a mess with terrible instructions that didn't work. A bunch of software packages that crashed. And the network engineers were tips off, as they tunnel between our network and the banks was too narrow, creating an unstable connection between us and them. Oh, and there were all sorts of database corruption issues.
There was also another bank that was using an old version of our software. The sells team had been trying to get them off our old software for over a year. They refuse to move. This bank was the last one using this version, and our organization wanted to completely cut support.
One of the issue we would have is that they had an overnight batch job that had an ETA to be done by 7 AM. The job would often get stuck because this version of the software didn't know how to fail when it was caught in an undesired state. So the job hung, and since the job didn't have logging, no one could tell if it failed unless the logs stopped moving for an hour. It was a heavily manually process that was annoying to deal with. So we would kill the JVM to "speed" the job up. One day I killed the JVM but the job was still late. They told me that they appreciated the effort, but that my job was only to report the problem and not fix it.
This got me caught up in a major scandal. Basically they wanted the job to always have issues everyday. Since this was critical for them, all we needed to do was keep reporting it, and then eventually this would cause the client to have to upgrade to our new software. It was our sales team trying to play dirty. It immediately made me a menace in the company.
For the next 6 months I was constantly harassed and bullied by management. My work was nitpicked. They asked me to come into work nearly everyday, and there was a point I worked 7 days with no off days. They were trying to run me so dry that I would quit. But I never did.
On my last day at the company, I was on a critical call with a customer, and my supervisor was also on the line. My supervisor made a request that made no sense, and was impossible. I told her it wasn't possible. She then scalded me on the call in front of customers. She said "I'm your supervisor, you're just a NOC technician, you do what I say and don't talk back". It was embarrassing to be reprimanded on a call with customers. I never quite recovered from that. I could fill myself steaming with anger. It was one of the first times in my adult life that I felt I really wanted to be violent towards someone. It was such a negative feeling I quit that day at the end of my shift with no job lined up.
I walked away from the job feeling very uncertain about my future, but VERY relieved. I paid the price, basically unable to find a job until a year and a half later. And even was forced to move back in with my mother. After I left, the company still gave my a severance. Probably because of the supervisor's unprofessional conduct in front of customers, and the company probably needed to save face. The 2008 crash kept me out of work until 2009. It did give me time to work on myself, and I swore to never let a job stress me out to that degree. That job was also my last NOC job and the last job where did shift work. My next few jobs was Application Support and I eventually moved into development full time, which is what I always wanted to do.
Anyway sorry if it's a bit long, but that's my burnout story.
Ever find something that's just faster than something else, but when you try to break it down and analyze it, you can't find out why?
I decided I'd test it with a typical discord bot-style workload (decoding a JSON theoretically from an API, checking if it contains stuff, format and then returning it). It was... 1.73x the speed of python.
(Though, granted, this code is more network dependent than anything else.)
Mean +- std dev: [kitsu-python] 62.4 us +- 2.7 us -> [kitsu-pypy] 36.1 us +- 9.2 us: 1.73x faster (-42%)
Me: Whoa, how?!
So, I proceed to write microbenches for every step. Except the JSON decoding, (1.7x faster was at least twice as slow (in one case, one hundred times slower) when tested individually.
The combination of them was faster. Huh.
By this point, I was all "sign me up!", but... asyncpg (the only sane PostgreSQL driver for python IMO, using prepared statements by default and such) has some of it's functionality written in C, for performance reasons. Not Cython, actual C that links to CPython. That means no PyPy support.
Everytime I see someone from Netherland complaining about their internet speeds I get angrier at IPSs. Amsterdam is the fucking biggest node on the fucking planet, if you can not get at least 25/10 in there, your IPS should just fucking die.1
So I just installed Elementary OS Loki on my older desktop and for that the wifi is incredibly slow, like 30 seconds to load googles home page. It also randomly stops working, and gives a no network connection. When this system was on windows I would average 50~ mb/s down speed, changing it to Linux I'm lucky to maintain 2mb/s. I've been googling for hours and nothing I try seems to work, any Linux pros here able to give me some suggestions. The network card in the PC is an Aetheros one, I it supports a,b,g,n and Bluetooth, I'm currently using the desktop with a Bluetooth mouse / kbd. (None of the hardware/setup has changed since using windows)2
Our ISP asked if I was satisfied with their service. I told them that it's okay, but some of our computers don't have enough powerful network card, and they can't use the internet on maximum speed, and they said that they could see it, too. WTF? I knew that the ISP's router is not the most secure thing, but it has a remote mode, which if of course OFF, and they still can see this, and maybe even more. Monitoring your traffic is a thing, but a home network should be private...2
Guys check out IOTA, get a light node wallet and buy some as long as it is still low. It is rising at a rising rate since some hours now.
IOTA is the solution to bitcoins speed and scalability problems. IOTA does not use the blockchain but instead a network called the tangle, which enables decentralized peer-to-peer transactions. There are no miners, no fees and the transaction validation speed depends on how many people are using the currency. One transaction requires your device to validate 2 other transactions through proof of work and therefore the system can never be overloaded by too many transaction requests.
Be warned though, the IOTA foundation is only currently building up the infrastructure, and people are just starting to trade since a few weeks so trasactions still may take a few hours.3
BSNL (Indian state run telco) offers 4GB data per day for 90 days at just INR 444 (around 7 USD). Sounds awesome right? But the catch is their network. It is so pathetic that you don't even get signal of you're inside a building. Even if you have full signal, data speed hardly reaches 0.5 Mbps.2
