Good Morning!, its time for practiseSafeHex's most incompetent co-worker!
Todays contestant is a very special one.
*sitcom audience: WHY?*
Glad you asked, you see if you were to look at his linkedin profile, you would see a job title unlike any you've seen before.
*sitcom audience oooooooohhhhhh*
were not talking software developer, engineer, tech lead, designer, CTO, CEO or anything like that, No No our new entrant "G" surpasses all of those with the title ..... "Software extraordinaire".
*sitcom audience laughs hysterically*
I KNOW!, wtf does that even mean! as a previous dev-ranter pointed out does this mean he IS quality code? I'd say he's more like a trash can ... where his code belongs
*ba dum tsssss*
Ok ok, lets get on with the show, heres some reasons why "G" is on the show:
One of G's tasks was to build an analytics gathering library for iOS, similar to google analytics where you track pages and events (we couldn't use google's). G was SO good at this job he implemented 2 features we didn't even ask for:
- If the library was unable to load its config file (for any reason) it would throw an uncatchable system integrity error, crashing the app.
- If anything was passed into any of the functions that wasn't expected (null, empty array etc.) it would crash the app as it was "more efficient" to not do any sanity checks inside the library.
This caused a lot of issues as some of the data needed to come from the clients server. The day we launched the app, within the first 3 hours we had over 40k crash logs and a VERY angry client.
Now, what makes this story important is not the bugs themselves, come on how many times have we all done something stupid? No the issue here was G defended all of this as the right thing to do!
.. and no he wasn't stoned or drunk!
G claimed if he couldn't get the right settings / params he wouldn't be able to track the event and then our CEO wouldn't have our usage data. To which I replied:
"So your solution was to not give the client an app instead? ... which also doesn't give the CEO his data".
He got very angry and asked me "what would you do then?". I offered a solution something like why not have a default tag for "error" or "unknown" where if theres an issue, we send up whatever we have, plus the file name and store it somewhere else. I was told I was being ridiculous as it wasn't built to track anything like that and that would never work ... his solution? ... pull the library out of the app and forget it.
... once again giving everyone no data.
G later moved onto another cross-platform style project. Backend team were particularly unhappy as they got no spec of what needed to be done. All they knew was it was a single endpoint dealing with very complex model. There was no Java classes, super classes, abstract classes or even interfaces, just this huge chunk of mocked data. So myself and the lead sat down with him, and asked where the interfaces for the backend where, or designs / architecture for them etc.
His response, to this day frightens me ... not makes me angry, not bewilders me ... scares the living shit out of me that people like this exist in the world and have successful careers.
G: "hhhmmm, I know how to build an interface, but i've never understood them ... Like lets say I have an interface, what now? how does that help me in any way? I can't physically use it, does it not just use up time building it for no reason?"
us: "... ... how are the backend team suppose to understand the model, its types, integrate it into the other systems?"
G: "Can I not just tell them and they can write it down?"
I'll just pause here for a moment, as you'll likely need to read that again out of sheer disbelief
I've never seen someone die inside the way the lead did. He started a syllable and his face just dropped, eyes glazed over and he instantly lost all the will to live. He replied:
" wel ............... it doesn't matter ... its not important ... I have to go, good luck with the project"
*killed the screen share and left the room*
now I know you are all dying in suspense to know what happened to that project, I can drop the shocking bombshell that it was in fact cancelled. Thankfully only ~350 man hours were spent on it
... yep, not a typo.
G's crowning achievement however will go down in history. VERY long story short, backend got deployed to the server and EVERYTHING broke. Lead investigated, found mistakes and config issues on every second line, load balancer wasn't even starting up. When asked had this been tested before it was deployed:
G: "Yeah I tested it on my machine, it worked fine"
lead: "... and on the server?"
G: "no, my machine will do the same thing"
lead: "do you have a load balancer and multiple VM's?"
G: "no, but Java is Java"
... and with that its time to end todays episode. Will G be our most incompetent? ... maybe.
Tune in later for more practiceSafeHex's most incompetent co-worker!!!33
I lost my sanity and googled ”FUCK YOU XCODE YOU FUCKING PIECE OF SHIT”...
That's how I found devRant.11
"4096 bit ~ 96 hours is what he said.
IDK why, but when he took the challenge, he posted that it'd take 36 hours"
As @cbsa wrote, and nitwhiz wrote "but the statement was that op's i3 did it in 11 hours. So there must be a result already, which can be verified?"
I added time because I was in the middle of a port involving ArbFloat so I could get arbitrary precision. I had a crude desmos graph doing projections on what I'd already factored in order to get an idea of how long it'd take to do larger
@p100sch speculated on the walked back time, and overstating the rig capabilities. Instead I spent a lot of time trying to get it 'just-so'.
Worse, because I had to resort to "Decimal" in python (and am currently experimenting with the same in Julia), both of which are immutable types, the GC was taking > 25% of the cpu time.
Performancewise, the numbers I cited in the actual thread, as of this time:
largest product factored was 32bit, 1855526741 * 2163967087, took 1116.111s in python.
Julia build used a slightly different method, & managed to factor a 27 bit number, 103147223 * 88789957 in 20.9s,
but this wasn't typical.
What surprised me was the variability. One bit length could take 100s or a couple thousand seconds even, and a product that was 1-2 bits longer could return a result in under a minute, sometimes in seconds.
This started cropping up, ironically, right after I posted the thread, whats a man to do?
So I started trying a bunch of things, some of which worked. Shameless as I am, I accepted the challenge. Things weren't perfect but it was going well enough. At that point I hadn't slept in 30~ hours so when I thought I had it I let it run and went to bed. 5 AM comes, I check the program. Still calculating, and way overshot. Fuuuuuuccc...
So here we are now and it's say to safe the worlds not gonna burn if I explain it seeing as it doesn't work, or at least only some of the time.
Others people, much smarter than me, mentioned it may be a means of finding more secure pairs, and maybe so, I'm not familiar enough to know.
For everyone that followed, commented, those who contributed, even the doubters who kept a sanity check on this without whom this would have been an even bigger embarassement, and the people with their pins and tactical dots, thanks.
So here it is.
A few assumptions first.
Assuming p = the product,
a = some prime,
b = another prime,
and r = a/b (where a is smaller than b)
w = 1/sqrt(p)
(also experimented with w = 1/sqrt(p)*2 but I kept overshooting my a very small margin)
x = a/p
y = b/p
1. for every two numbers, there is a ratio (r) that you can search for among the decimals, starting at 1.0, counting down. You can use this to find the original factors e.x. p*r=n, p/n=m (assuming the product has only two factors), instead of having to do a sieve.
2. You don't need the first number you find to be the precise value of a factor (we're doing floating point math), a large subset of decimal values for the value of a or b will naturally 'fall' into the value of a (or b) + some fractional number, which is lost. Some of you will object, "But if thats wrong, your result will be wrong!" but hear me out.
3. You round for the first factor 'found', and from there, you take the result and do p/a to get b. If 'a' is actually a factor of p, then mod(b, 1) == 0, and then naturally, a*b SHOULD equal p.
If not, you throw out both numbers, rinse and repeat.
Now I knew this this could be faster. Realized the finer the representation, the less important the fractional digits further right in the number were, it was just a matter of how much precision I could AFFORD to lose and still get an accurate result for r*p=a.
Fast forward, lot of experimentation, was hitting a lot of worst case time complexities, where the most significant digits had a bunch of zeroes in front of them so starting at 1.0 was a no go in many situations. Started looking and realized
I didn't NEED the ratio of a/b, I just needed the ratio of a to p.
Intuitively it made sense, but starting at 1.0 was blowing up the calculation time, and this made it so much worse.
I realized if I could start at r=1/sqrt(p) instead, and that because of certain properties, the fractional result of this, r, would ALWAYS be 1. close to one of the factors fractional value of n/p, and 2. it looked like it was guaranteed that r=1/sqrt(p) would ALWAYS be less than at least one of the primes, putting a bound on worst case.
The final result in executable pseudo code (python lol) looks something like the above variables plus
while w >= 0.0:
if (p / round(w*p)) % 1 == 0:
x = round(w*p)
y = p / round(w*p)
if x*y == p:
w = w + i
Still working but if anyone sees obvious problems I'd LOVE to hear about it.39
Me when I'm forced, at gunpoint, to work with a butchered Wordpress site with 116 activated plugins.8
“Web does not need reactive programming”
“Everybody use PHP now, we don’t need your fancy functional stuff here”
This and other hilarious things I’ve been told through my career, as well as the story of doctor who tried to teach other doctors to wash their hands but lost his sanity because they rejected him, are in my fresh article.
Ok, so when I inherit a Wordpress site I've really stopped expecting anything sane. Examples: evidence that the Wordpress "developer" (that term is used in the loosest sense possible) has thought about his/her code or even evidence that they're not complete idiots who wish to make my life hell going forwards.
Have a look at the screen shot below - this is from the theme footer, so loaded on every page. The screenshot only shows a small part of the file. IT LITERALLY HAS 3696 lines.
Firstly, lets excuse the frankly eye watering if statement to check for the post ID. That made me face palm myself immediately.
The insanity comes for the thousands of lines of JQuery code, duplicated to hell and back that changes the color of various dividers - that are scattered throughout the site.
To make things thousands of times worse, they are ALL HANDED CODED.
When a good developer notes repetition ways to abstract crap away is the first thought that comes to mind.
Hell, when I was first learning to code god knows how long ago I always used functions to avoid repetition.
In this case, with a few seconds though this "developer" could have created a single JQuery handler and use data attributes within the HTML. Hell, as bad as that is, it's better than the monstrosity I'm looking at now.
I'm aware Wordpress is associated with bad developers due to it's low barrier to entry, but this site is something else.
The scary thing is that I know the agency that produced this. They are very large, use Wordpress exclusively and have some stupidly huge clients that would be know nationally.
Wordpress truly does attract some of the most awful "developers" and deserves it's reputation.
If you're a good developer and use Wordpress I feel sorry for you, as you're in small numbers from my experience.
Rant over, have vented a bit and feel better. Thanks Devrant.6
I am so fucking lost.
I literally have zero expectations from life for now and future.
There was a time when I had so much clarity in my life. Rather, I was known for it.
Folks used to reach me out for guidance and my approaches even worked for others.
I was goal oriented and biased towards action. Failing and learning from it, I used to make things happen and with constant feedback kept progressing.
While none of that has changed, I still feel lost and numb. No, I am not depressed or suffering through any mental illness. I am physical active and able to feel the happiness.
But the recent incident with a narcissistic, left me emotionally handicap. I can no longer feel any kind of love or affection. I overcame the damage done and healed myself.
But now, I am done. Even if I engage with anyone for a relationship it would be mostly for sex. I can care for people around me and be affectionate towards them but when it comes to an intimate relationship, I feel it's not something I can do in this lifetime. I tried multiple times but failed.
These days, all I am doing is putting my heads down and working like crazy. Never in my life I worked more than 10 hours in an entire week. Now, I work 10+ hours everyday. During that time, I am highly productive.
And in my free time, I am busy housekeeping different life problems. Either paying bills, figuring out an insurance, planning some investment, or making some kind of life decision.
It's draining me. I feel as if I am losing sanity. But that's the only thing I am able to do.
Maybe it's the lockdown effect. Maybe some damage is yet to be healed.
But I got nothing better to do. I have some good ideas. Not those hipster-ish disruptive Million dollar ideas, but decent enough to solve a problem for a strong use case.
However, all of this is becoming overwhelming these days. Because decision making is complex and difficult task. It can make or break the future.
As of now I am confused how should I go about pursuing two of the important projects that I want to accomplish.
1. Migrating out of Google ecosystem. Is it even practically possible for my use case? What are the alternatives? Planning to opt in for a paid cloud storage so have to factor in that aspect as well.
I want to keep this new setup only for official use like bank and government stuff. Maybe family and close friends. Then have current ids for public logins and sharing it with retards whom I can block or ignore if they harass me. The research is overwhelming but having a structured setup gives insane amount of efficiency when life is spam free.
2. Migrating my Pihole and OpenVPN setup out of Digital Ocean to GCP. Primarily because $5 is a lot of amount for my computational requirements and Google has used my data enough, for me to use the free tier.
However, there isn't a simple script for a tech noob like me, to go ahead and setup something. I did find a Github repository but the documentation is kind of outdated so RTFM failed for me.
I don't know whether to pursue my start-up or let it go and focus on moving to Europe.
It's just so fucking stupid to even exist. And let's not forget taxes. Bloody taxes.30
It's been two months since I've left my previous job, after 1.5 years. I never had the feeling my boss trusted his dev team, since he was checking up on us regularly, even though we had planned out a sprint and work for us was "clear". I say "clear", because every single feature on this project was pretty much half-baked, since they were just ideas our boss/PO (same person) on the spot and were labeled as "the next big thing" without every properly writing them out as user stories. Every demo came with a bunch of criticism, because features weren't implemented "as he imagined", because what do you know, the user stories weren't properly described anyway. Bringing that up as counter-argument also made him angry every time, so that didn't help much either. The launch of the platform was also postponed every time because of vague reasons, so that didn't make the project any more interesting either.
It took a while before I got sick of this of this pretty hopeless situation and toxic environment. Mind you, it was my first job since I graduated, so I was a bit naive thinking the working environment would improve and aforementioned company issues would be resolved over time. Eventually, I ran out of patience and motivation, so I finally bit the bullet and handed in my resignation letter.
From that moment, I at least had an end in sight, since I was still obliged to do my four-week notice period, which felt like an eternity. The borderline childish and sociopathic behaviour of my boss didn't make it any better (e.g. checking up on me even more, more mistrust, randomly accusing me of ruining the working atmosphere because I shared a meme with a colleague of mine and didn't involve him, going lunching with all of my colleagues but explicitly asking me to stay at work, ...). Being forced to work from home the last 2 weeks as part of the country's lockdown measures at least helped my sanity a bit, since I had the comfort of my home office and not the frequent "looking over your shoulders to check if you're still working".
By the last day of my notice period, I was bitter, exhausted, lost confidence in my skills and had completely lost my joy of being a developer. I had to physically meet with my boss one more time to hand in the company laptop. He thanked me for my service and said that we'd keep in touch. I hope I won't keep that promise (he made a lot of false promises before, too), because I'd rather never encounter him ever again. It felt like a huge relief to finally close the door of this bad experience behind me for good.
Now, 2 months later, I've got a new job and rediscovered my joy for coding, mostly thanks to the complete opposite of a toxic environment here, management which actually has respect and faith in me and a challenging but fun project. My mental state has made a complete turnaround compared to two months ago. I have absolutely no regrets of switching jobs. If only I had made that decision sooner.4
Linux networking: A tragedy in three acts
Wherein the system administrator writes their /etc/network/interfaces file as is the custom.
Wherein the kafkaesque outputs of basic networking commands threaten basic sanity. Behold:
# ifup ens3:1
RTNETLINK answers: File exists
Failed to bring up ens3:1.
# ifdown ens3:1
ifdown: interface ens3:1 not configured
Wherein all sanity is lost:
The ridiculous and shameful story of how simply "installing Windows" saved my hard drive from the garbage.
(Also update on https://devrant.com/rants/3105365/)
It started with my root partition turning read-only all of a sudden. Some quick search suggested that I should check the sanity of my hard drive, by running a SMART test, which failed of course. I backed up my data using ddrescue and ran a badblocks over the whole thing, which found around 800 unreadable blocks in a row. I was ready to bid farewell to my drive, but as a last resort, instead of the trash, I brought it to this place where they claimed they can repair the damaged hard drives by "surgery".
To my surprise, they returned my drive the next week, saying it is all well now, and charged me 1/8 the price of a new drive, with a refund guarantee if there was a problem in two days. There was a problem right there: I ran another SMART test which failed again, and also the faulty blocks were still unreadable! So I stormed the place and called for my refund, showing the failed SMART report. The only answer I would get from the staff was "Have you tried installing Windows?".
I usually try to be patient in such situations; I really don't like to declare publicly that "not everyone uses that stinky piece of rotten software you call an OS", but their suggestion seemed totally irrelevant! I got all types of IO errors all over the damn thing and they told me to install Windows. Why? Because this was the only test they would rely on. At last I managed to meet the "technician" there and showed him the IO errors: tried to read the bad sectors with dd and failed. He first mumbled somethings like "Have you checked the connector?" or "Are these the same blocks?", but after he ran out of bullshit, he said "Why don't you just install Windows first and see if that helps?" and I was ready to explode in his face!
"You test drives by installing Windows, just because it will make a nasty NTFS partition and probably does an fsck? If you shut your mouth for a sec and open your eyes you'll see this is a shit load of IO errors we got here: You can't install Windows, you can't even make an NTFS here, because it will try to zero-the-fuck-out the damn partition and it will face the same fucking IO error that I'm showing you right now in almost one single fucking system call!"
"I don't know this kind of test you are using. We have our own tests and they've passed successfully. So all I can do is to give you a Windows CD if you want."
"I don't need a Windows CD. I will just try to make an NTFS partition on the error spot and I will fail."
"Ok. Then call me when your done."
I was angry, not only because I felt they're just trying to avoid a refund, but also because I knew I've lost my drive. But just with hope that I could get my money back, I made a small partition over the error spot and ran `mkfs.ntfs` on it. I was ready to show the failure to the guy, but I looked more precisely and saw that "the filesystem was created successfully!" I was sure something is nor write. I then successfully mounted the new partition, write over it and read it again. I even dd'ed the blocks again, and this time there was no IO error. All of a sudden everything was fine.
I didn't know what happened. Maybe it just needed a write, while I'd just tried to read from those blocks. But anyway, I didn't called the technician guy again. I just thanked one of the staff there and said that my problem was solved. I then ran a successful SMART test and then restored my backup. Ridiculous like that.
I'm still not sure if my drive will continue to live with no more problems. I also have no explanation for what happened. (I appreciate any help on this https://superuser.com/questions/...) But I really like to see the look on the poor guy's face when he finds out that trying to install Windows just saved my ass!11
Let's see what's on the menu today:
* Web Application Catastrophe Special *
Includes, but not limited to:
- Orphaned server processes in the configuration management cluster
- Microservice back-end architecture with no API documentation
- Poorly implemented cache microservice with no documentation
- Stale data causing everything to be shown as down in production, despite everything running fine
Cost: 1 developer's sanity
So as expected, due to the rush of the submission on Friday, the app was rejected.
I'm fairly certain they never got past the first screen or two.
We have some things to fix, and some things to tackle properly now, which is quite nice, however the current main issue numero uno is that an Apple developer account can take up to 10 days to be created, and Go Live is next Monday.
I wonder who will get the blame for not taking on the "Investigate the iTunes release process" ticket that was in Jira, assigned to someone for ~4 months.
I watched an episode of Brooklyn 99. Cop comedy show for those of you who don't know. They introduced me to the monty hall problem? My brain refuses to understand it and im rapidly losing my mind.
Has anyone here ever written a program that tests it? I can't read math theorems for shit. But I can read code. And I need my sanity back.2
So today I finally lost my sanity and public'ed by somewhat Chromium OS board overlay and built on top of that already...
