https://git.kernel.org/…/ke…/... sure some of you are working on the patches already, if you are then lets connect cause, I am an ardent researcher for the same as of now.
So here it goes:
As soon as kernel page table isolation(KPTI) bug will be out of embargo, Whatsapp and FB will be flooded with over-night kernel "shikhuritee" experts who will share shitty advices non-stop.
1. The bug under embargo is a side channel attack, which exploits the fact that Intel chips come with speculative execution without proper isolation between user pages and kernel pages. Therefore, with careful scheduling and timing attack will reveal some information from kernel pages, while the code is running in user mode.
In easy terms, if you have a VPS, another person with VPS on same physical server may read memory being used by your VPS, which will result in unwanted data leakage. To make the matter worse, a malicious JS from innocent looking webpage might be (might be, because JS does not provide language constructs for such fine grained control; atleast none that I know as of now) able to read kernel pages, and pawn you real hard, real bad.
2. The bug comes from too much reliance on Tomasulo's algorithm for out-of-order instruction scheduling. It is not yet clear whether the bug can be fixed with a microcode update (and if not, Intel has to fix this in silicon itself). As far as I can dig, there is nothing that hints that this bug is fixable in microcode, which makes the matter much worse. Also according to my understanding a microcode update will be too trivial to fix this kind of a hardware bug.
3. A software-only remedy is possible, and that is being implemented by all major OSs (including our lovely Linux) in kernel space. The patch forces Translation Lookaside Buffer to flush if a context switch happens during a syscall (this is what I understand as of now). The benchmarks are suggesting that slowdown will be somewhere between 5%(best case)-30%(worst case).
4. Regarding point 3, syscalls don't matter much. Only thing that matters is how many times syscalls are called. For example, if you are using read() or write() on 8MB buffers, you won't have too much slowdown; but if you are calling same syscalls once per byte, a heavy performance penalty is guaranteed. All processes are which are I/O heavy are going to suffer (hostings and databases are two common examples).
5. The patch can be disabled in Linux by passing argument to kernel during boot; however it is not advised for pretty much obvious reasons.
6. For gamers: this is not going to affect games (because those are not I/O heavy)
Meltdown: "Meltdown" targeted on desktop chips can read kernel memory from L1D cache, Intel is only affected with this variant. Works on only Intel.
Spectre: Spectre is a hardware vulnerability with implementations of branch prediction that affects modern microprocessors with speculative execution, by allowing malicious processes access to the contents of other programs mapped memory. Works on all chips including Intel/ARM/AMD.

I'm not enjoying my current experience with the web.
I feel sad, alone most of the time.
Let me disclaim first that I don't have like an apocalyptic view of the world, I actually think it's improving (in very broad terms).
I also understand that the web is a complex thing and everyone being happy with is going to be very unlikely, specially as more and more people use it, since the entropy will naturally increase.
I don't have solid evidence of what I'm saying next and I'm not even entirely what exactly I'm saying, but maybe I'm onto something.
I feel that when the internet first started, businessmen were like "meh, geek stuff".
But slowly, things changed, and every greedy person tried to just fucking unload his greed filled cum onto it
And now it feels like 1984. And I hate when people reeeee 1984. But it does feel like it.
The ads are like "ok, I know you like that other shit, but CHECK THIS SHIT OUT".
It's AI driven to maximize profits, with little care for people happiness.
I miss when youtube had related videos. The algorithm wasn't perfect but at least it was exactly that, related videos.
Now though, youtube likes to be smart. But not smart in a way that enriches your youtube experience.
It's smart in a way that maximizes ad revenue.
"what? did you think we were going to use AI to make you happier? that we were going to enrich your youtube experience?
NO MOTHER FUCKER! OF COURSE NOT. We're gonna use it to show you whatever shit that will make us richer faster."
Controls for customizing the recommended videos behaviour? Pff, no.
They're gonna decide for you what it is that you like
They're going to decide what you should be watching.
Everytime i turn on my samsung tv, the youtube app recomends me watching "BETTER THAN SEX EYE LINER". Jesus christ, what the shitcum, I'm the only motherfucker on the house that uses youtube, and I couldn't care less about this cunt's disguised ad video, let alone fucking eye liners.
Why youtube, why do you promote whatever porn video VEVO uploads?
Why do you ruin every youtube rewind?
Why do you pander to the lowest common denominator?
Why can't you be shining beacon, a moral company considering you're a cultural icon?
Fuck you youtube, and while we're at it, fuck you too samsung, I must have been drunk the day I bought this shitty closed source software piece of shit "smart".
And these are just 2 companies. The internet is FILLED with these greedy bastards. They have no passion for their products, for making people happy. They only have passion for the MUNNNEY.
Thanks a lot business schools, thanks a lot CEOs of the world, thanks for making the world a happier place.
Ok, now that I said that, I want to back up a bit.
Youtube may bot be perfect, but it's ad revenue system enables some youtubers I love to be able to make that their careers.
I appreciate that, so maybe youtube isn't that bad... so sorry for saying those horrible things man!8 -
Voting feels like shit.
Seriously. Why? Because I have to vote for parties and representatives that might have one interest in common with me but go against my points of view almost all of the time. "We'll introduce a freedom of information act and legalize weed for better drug policy and youth protection!" -- WOW Great I'll vote for yo .. " ...and we'll also come to your home kill your dog, rape your family and shit in your back yard." -- oh f*** WHY? why do I have to live in a system were I am constantly forced to trade shit for even worse shit? Why can't I vote for policies or at least some kind of 'single' - issue representative?
I know that solving this problem is not easy and I do not claim to have the magical solution. "Not voting is even worse" sure but I am getting so fucking tired of it. It doesn't feel like progression and it sure as hell does not feel like it matters because in the end of the day you are just voting for the party that's at least going to use lube when raping you. I hate these ad hominem politics where we don't discuss the ideas but the people who represent them. I honestly don't give a fuck about who you are, if you're gay, married, or are left-wing, right-wing, conservative or liberal, in the end its about finding a good solution for everyone and not about the people implementing it. I don't care about politicians private lifes or worldviews (in terms of ideals, morals, religion etc.) , I care about finding the solutions to problems and having a wide array of opinions in order to discuss ideas and to find a valid and good way to go forward. "you can't agree with that person at all, because he's evil", yeah you know what? I don't care. It's about the ideas, arguments, discussions and solutions, not about the people who discuss them.
"I made a discovery today. I found a computer. Wait a second, this is cool. It does what I want it to. If it makes a mistake, it's because I
screwed it up. Not because it doesn't like me...
Or feels threatened by me...
Or thinks I'm a smart ass...
Or doesn't like teaching and shouldn't be here...
Damn kid. All he does is play games. They're all alike."33 -
So... I've got a confession to make.
I'm no longer a Dev. After the disaster that was my last commercial gig, I went and got a sec Ops role... And I love it. It's just technical problem solving and explaining all the way.
Don't get me wrong, I still love to code. But that's exactly the thing. As a commercial developer employed by corporations, I spent close to 80 % of my time not coding, but in useless meetings, or trying to figure out just what my colleagues thought was "common sense", reverse engineering their work and documenting how to get it running, etc. Basically, fixing shit for braindead academics with next to no real world experience.
Now, when I code, I get to do it on my own terms, with my own stack and as much comments and docs as I want to have. I own my time, and the only ones that are allowed to interrupt me is the local fire department.
I can do what I'm fucking passionate about and leave the rest for the useless people.4 -
I propose that the study of Rust and therefore the application of said programming language and all of the technology that compromises it should be made because the language is actually really fucking good. Reading and studying how it manages to manipulate and otherwise use memory without a garbage collector is something to be admired, illuminating in its own accord.
BUT going for it because it is a "beTter C++" should not constitute a basis for it's study.
Let me expand through anecdotal evidence, which is really not to be taken seriously, but at the same time what I am using for my reasoning behind this, please feel free to correct me if I am wrong, for I am a software engineer yes, I do have academic training through a B.S in Computer Science yes, BUT my professional life has been solely dedicated to web development, which admittedly I do not go on about technical details of it with you all because: I am not allowed to(1) and (2)it is better for me to bitch and shit over other petty development related details.
Anecdotal and otherwise non statistically supported evidence: I have seen many motherfuckers doing shit in both C and C++ that ADMIT not covering their mistakes through the use of a debugger. Mostly because (A) using a debugger and proper IDE is for pendejos and debugging is for putos GDB is too hard and the VS IDE is waaaaaa "I onlLy NeeD Vim" and (B) "If an error would have registered then it would not have compiled no?", thus giving me the idea that the most common occurrences of issues through the use of the C father/son languages come from user error, non formal training in the language and a nice cusp of "fuck it it runs" while leaving all sorts of issues that come from manipulating the realm of the Gods "memory".
EVERY manual, book, coming all the way back to the K&C book talks about memory and the way in which developers of these 2 languages are able to manipulate and work on it. EVERY new standard of the ISO implementation of these languages deals, through community effort or standard documentation about the new items excised through features concerning MODERN (meaning, no, the shit you learned 20 years ago won't fucking cut it) will not cut it.
THUS if your ass is not constantly checking what the scalpel of electrical/circuitry/computational representation of algorithms CONDONES in what you are doing then YOU are the fucking problem.
Rust is thus no different from the original ideas of the developers behind Go when stating that their developers are not efficient enough to deal with X language, Rust protects you, because it knows that you are a fucking moron, so the compiler, advanced, and well made as it is, will give you warnings of your own idiotic tendencies, which would not have been required have you not been.....well....a fucking idiot.
Rust is a good language, but I feel one that came out from the necessity of people writing system level software as a bunch of fucking morons.
This speaks a lot more of our academic endeavors and current documentation than anything else. But to me DEALING with the idea of adapting Rust as a better C++ should come from a different point of view.
Do I agree with Linus's point of view of C++? fuck no, I do not, he is a kernel engineer, a damn good one at that regardless of what Dr. Tanenbaum believes(ed) but not everyone writes kernels, and sometimes that everyone requires OOP and additions to the language that they use. Else I would be a fucking moron for dabbling in the dictionary of languages that I use professionally.
BUT in terms of C++ being unsafe and unsecured and a horrible alternative to Rust I personaly do not believe so. I see it as a powerful white canvas, in which you are able to paint software to the best of your ability WHICH then requires thorough scrutiny from the entire team. NOT a quick replacement for something that protects your from your own stupidity BY impending the use of what are otherwise unknown "safe" features.
To be clear: I am not diminishing Rust as the powerhouse of a language that it is, myself I am quite invested in the language. But instead do not feel the reason/need before articles claiming it as the C++ killer.
I am currently heavily invested in C++ since I am trying a lot of different things for a lot of projects, and have been able to discern multiple pain points and unsafe features. Mainly the reason for this is documentation (your mother knows C++) and tooling, ide support, debugging operations, plethora of resources come from it and I have been able to push out to my secret project a lot of good dealings. WHICH I will eventually replicate with Rust to see the main differences.
Online articles stating that one will delimit or otherwise kill the other is well....wrong to me. And not the proper approach.
Anyways, I like big tits and small waists.14 -
Internships are fucking bullshit and if more senior developers were to take the role of an actual mentor to coach juniors properly then the state of software engineering would be better.
Some people can be let down easy in terms of "this is not for you bruh", others can be built. I know that social interactions are not common for a lot of the morons in here, but being polite and kind is relatively simple if you know what you are doing. Being a dickhead != "royal levels of expertise" and if we were to coach more people into proper development practices then software would not be in such a shitty state.
For an environment that thrives in cooperation I find it hard to believe that we are still subjecting new people to the field to what can be considered slavery with little to actual no monetary compensation.
I removed many of the requirements for the application to a software developer job where I am at (I am the boss, I get to do shit like that) and my fight with HR was "I would rather someone fresh from college that I can coach properly than some dickhead with years on the field that won't listen to anything else than their own words"
Sure it would be slow, sure it would be hard, nothing ever is that simple, but my idea is "train this mkfer, level the fuck out of him, let him be off to great shit rather than giving him to some dickhead that will treat him like shit on account of being a newbie"
And yes, I do know how and what can go bad, I am going to have someone desinging shit in basic html/js/css with some php here and there not giving them the keys to every server I control. Thank you for your fucking concerns, I know what I am doing.
the experiment fails? GOOD more data for me.
Plus, you learn more when you teach others.16 -
Despite common sense, I think technology is not making our lives easier. It's just build chaos on top of chaos.
Take server-side programming for instance.
First you have to find someone to host your thing, or a PaaS provider. Then you have to figure out how much RAM and storage you need, which OS you're going to use. And then there's Docker (which will run on top of a VM on AWS or GCP anyway, making even less sense). And then there's the server technology: nginx, Apache (and many many more; if, that is, you're using a server at all). And then there are firewalls, proxies, SSL. And then you go back to the start, because you have to check if your hosting provider will support the OS or Docker or your server. (I smell infinite recursion here.)
Each of these moving parts come with their own can of worms in terms of configuration and security. A whole bible to read if you want to have the slightest clue about what you're doing.
And then there's the programming language to use and its accompanying frameworks. Can they replace the server technology? Should you? Will they conflict with each other and open yet another backdoor into your system? Is it supported by your hosting provider? (Did I mention an infinite recursion somewhere?)
And then there's the database. Does it have a port to the language/framework of your choosing? Why does it expose an web interface? Is it supposed to replace your server? And why are its security features optional again? (Just so I have to test both the insecure and the secure environments?)
And you haven't written a single line of code yet, mind you.4 -
I’m developing a fairly sophisticated desktop app in Python with PyQt5 as the widget set. Because my partner insists that all the kids these days love Python.
Piss on Python. And that goes double for PyQt5.
I’m on the absolute hardest section of the app. It’s a fairly complex import of data from PDF reports. There are so many different parts that I decided to go with a wizard.
So, I built a QWizard in Qt Designer. It generates a C++ .ui file, but you just truck it over to the command line and run this pyuic5 command, and it converts to a handy dandy Python class. Woo. You can subclass it and consume it from your Python script.
Sounded SO MUCH EASIER than writing the wizard from scratch. But OH NO. I need to do custom validation on my custom text control at every stage to control when the Next and Finish buttons are enabled, which means I gotta overwrite some damn event.
But I can’t. Because I can’t subclass the individual pages. Because they’re part of the same damn file and the wizard offers no access to them.
I’m almost certain that I’m going to have to completely redesign the wizard so that it’s pages are in separate files, which means I have to recode the bitch as well.
The cherry on top is that there’s zero documentation for this specific thing. None. No QWizard documentation exists for PyQt5 (if there is, they’re doing a damn good job of hiding it), so I have to read the documentation for PyQt4. Not the same animal. Close, but different. Even with the differences aside, this documentation is minimal and useless. “We’re going to tell you in very general terms what you should do, but we’ll give you zero idea how to do it. And we know the very common code method you’ll want to try first won’t work.”
And getting at this stuff when you do it in Qt Designer is WAY different. And all that documentation is in C++. Because apparently you HAVE to speak C++ if you want any real info about PyQt. Because that’s perfectly reasonable, right?
So, now I’ve lowered myself and posted a question on Stack. Because, hey, once you get past the power-tripping, mouth-breathing, basement-dwelling, neck-bearded high school punching bags picking apart your question rather than, I dunno..., BEING HELPFUL, sometimes you can get good info there. Sometimes. They seriously saved my ass at least one time.
But yeah. Fuck Python. Fuck everything Qt.17 -
Why are some seniors just so full of themselves? I mean... Yeah I know that they know more than me (junior) but common, you don't have to rub it in my face! Tho I'd rather have it that they rub it in my face than them explain it with the most difficult terms / hardest words they could find in the dictionary!!
I also don't need them to complain that I'm on a different platform than them (while they help me)4 -
Is your code green?
I've been thinking a lot about this for the past year. There was recently an article on this on slashdot.
I like optimising things to a reasonable degree and avoid bloat. What are some signs of code that isn't green?
* Use of technology that says its fast without real expert review and measurement. Lots of tech out their claims to be fast but actually isn't or is doing so by saturation resources while being inefficient.
* It uses caching. Many might find that counter intuitive. In technology it is surprisingly common to see people scale or cache rather than directly fixing the thing that's watt expensive which is compounded when the cache has weak coverage.
* It uses scaling. Originally scaling was a last resort. The reason is simple, it introduces excessive complexity. Today it's common to see people scale things rather than make them efficient. You end up needing ten instances when a bit of skill could bring you down to one which could scale as well but likely wont need to.
* It uses a non-trivial framework. Frameworks are rarely fast. Most will fall in the range of ten to a thousand times slower in terms of CPU usage. Memory bloat may also force the need for more instances. Frameworks written on already slow high level languages may be especially bad.
* Lacks optimisations for obvious bottlenecks.
* It runs slowly.
* It lacks even basic resource usage measurement.
Unfortunately smells are not enough on their own but are a start. Real measurement and expert review is always the only way to get an idea of if your code is reasonably green.
I find it not uncommon to see things require tens to hundreds to thousands of resources than needed if not more.
In terms of cycles that can be the difference between needing a single core and a thousand cores.
This is common in the industry but it's not because people didn't write everything in assembly. It's usually leaning toward the extreme opposite.
Optimisations are often easy and don't require writing code in binary. In fact the resulting code is often simpler. Excess complexity and inefficient code tend to go hand in hand. Sometimes a code cleaning service is all you need to enhance your green.
I once rewrote a data parsing library that had to parse a hundred MB and was a performance hotspot into C from an interpreted language. I measured it and the results were good. It had been optimised as much as possible in the interpreted version but way still 50 times faster minimum in C.
I recently stumbled upon someone's attempt to do the same and I was able to optimise the interpreted version in five minutes to be twice as fast as the C++ version.
I see opportunity to optimise everywhere in software. A billion KG CO2 could be saved easy if a few green code shops popped up. It's also often a net win. Faster software, lower costs, lower management burden... I'm thinking of starting a consultancy.
The problem is after witnessing the likes of Greta Thunberg then if that's what the next generation has in store then as far as I'm concerned the world can fucking burn and her generation along with it.6 -
I just felt like Google is the best player out there in terms of Companies.
Seriously, Well played Google.
This is not a negative opinion, I am just awe-struck at its tactics.
See, Google is currently the biggest name in terms of development in Android, ML and multi-platform software but no one can say it being a monopoly due to its dedication to open source community.
Recently Android emerged out to be One of the Biggest , most advanced, trusted and loved Technology . It saw great achievements, and up till 2016-17, it was at its peek. BUT when the market started shifting towards multi-platform boons and Ai, it got its hands into that too with its flutter and kotlin environment
One could have a negative opinion about this, But i can't seem to engulf the vast amounts of positive situations i see in this:
1) this IO18 (and many months before that) saw ML/AI being incorporated in Android (also the arcore, proje tango and many more attempts in the past) meaning that Android will not officially "die". It will just become an extremely encouraged platform( not just limited to mobiles) and a beginning of the robot -human reality ( a mobile is handling everything of your everyday life: chats, music apps sxhedules, alarms, and with an actively interacting ML, it won't be long when Android comes installed in a green bug lime droid robot serving you tea xD). Meanwhile the market of Windows games may shift to mobiles or typically " Android games" (remember, Android won't be limited to mobiles)
2)java may or may not die. The animations and smooth flow it seems to provide is always appreciated but kotlin seems to do so too. As for the hard-core apps, they are usually written in c++ .So java is in the red zone
3) kotlin-native and Flutter will be the weapons of future , for sure. they will be developing multi-platform softwares and will be dividing the market of softwares into platform specific softwares(having better ml/ai interactions,animations) and platform independent apps(access and use anywhere softwares).
And where does google stand?Its the lord varys of game of thrones which just supports and enhances the people in the realm. So it benefits the most . That's a company for you, ladies and gentlemen! If seen from common eyes they seem to be the best company ever and our 1 true king but it can also be a very thick fur cloak hiding their negetive policies and tactics , if any.
Well played, Google.16 -
Back when I was still in school for comp sci we had an advanced software engineering and design class with c++. At this time, everyone was expected to be proficient enough with cpp to go ahead and properly work with whatever the instructor would throw at us. And pretty much everyone was since past classes included a lot of c++ development. Of course, efficient at least related to academic studies rather than actual real world development.
Our teacher would mix in a lot pf phyisics and mathematics into what we were doing, something that I greatly enjoyed, while at the same time putting real world value concerning cpp best practices to avoid common pitfalls in the development of said language. Since most bugs seemed to be memory based he would be particularly strict about that.
One classmate, good friend and an actual proper developer now a days would ALWAYS forget to free his resources...ALWAYS for whatever fucking reason he would just ignore that shit, regardless of how much the instructor would make a point on it.
At one point during class on a virtual lecture the dude literally addressed a couple of students but when he got to my boy in particular he said: "you are the reason why people are praying to Mozilla and Hoare to release Rust as fast as possible into a suitable alternative to high performant code in C++, WHY won't you pay attention to how you deal with memory management?"
And it stuck with me. I merely a recreational cpp dev, most of my profesional work is done on web development, so I cannot attest to all the additional unsafe code that people encounter in the wild when dealing with cpp on a professional level.
But in terms of them common criticisms of C and C++ for which memory is so important to work with, wouldn't you guys say that it comes more from the side of people just not knowing what they are doing rather than a fault on the language itself?
I see the merits and beauty of Rust, I truly do, it is a fantastic language, with a standardized build system and a lot of good design put into it. But I can't really fathom it being the cpp killer, if anything, the real cpp killers are bad devs that just don't know what they are doing or miss shit.
What do y'all ninjas think?8 -
Udemy is full of crap.
I got some course that had been "discounted" from $200 (I already mentioned it is an ugly trick) and it was over in like 20 minutes. The fuck?!
All the info they gave was either common sense or something you could find on the first paragraph of the Wikipedia article on the given topic (it was a soft skills course, not a technical one).
Just junk.
Maybe there are some gems out there, but I'm not sure I would risk it again.
Udemy feels like the Booking.com of courses in terms of deceitful UX, but it's not nearly as useful.
Maybe you guys have found something good there that you could say is a bargain? If so, please let me know.10 -
I continue to internally read and study about Smalltalk in an effort to see where we might have FUCKED UP and went backwards in terms of software engineering since I do not believe that complex source code based languages are the solution.
So I have Pharo. Nothin to complex really, everything is an object, yet, you do have room for building DSL's inside of it over a simple object model with no issue, the system browser can be opened across multiple screens (morph windows inside of a smalltalk system) for which you can edit you code in composable blocks with no issues. Blocks being a particular part of the language (think Ruby in more modern features) give ample room for functional programming. Thus far we have FP and OO (the original mind you) styles out in the open for development.
Your main code can be executed and instantly ALTER the live environment of a program as it is running, if what you are trying to do is stupid it won't affect the live instance, live programming is ahead of its time, and impressive, considering how old Smalltalk is. GUI applications can be given headless (this is also old in terms of how this shit was first distributed) So I can go ahead and package the virtual machine with the entire application into a folder, and distribute it agains't an organization "but why!!!! that package is 80+ mbs!") yeah cuz it carries the entire virtual machine, but go ahead and give it to the Mac user, or the Linux user, it will run, natively once it is clicked.
Server side applications run in similar fashion to php, in terms of lifecycles of request and how session storage is handled, this to me is interesting, no additional runtimes, drop it on a server, configure it properly and off you go, but this is common on other languages so really not that much of a point.
BUT if over a network a user is using your application and you change it and send that change over the network then the the change is damn near instant and fault tolerant due to the nature of the language.
Honestly, I don't know what went wrong or why we are not bringing this shit to the masses, the language was built for fucking kids, it was the first "y'all too stupid to get it, so here is simple" engine and we still said "nah fuck it, unlimited file system based programs, horrible build engines and {}; all over the place"
I am now writing a large budget managing application in Pharo Smalltalk which I want to go ahead and put to test soon at my institution. I do not have any issues thus far, other than my documentation help is literally "read the source code of the package system" which is easy as shit since it is already included inside. My scripts are small, my class hierarchies cover on themselves AND testing is part of the system. I honestly see no faults other than "well....fuck you I like opening vim and editing 300000000 files"
And honestly that is fine, my questions are: why is a paradigm that fits procedural, functional and OBVIOUSLY OO while including an all encompassing IDE NOT more famous, SELECTION is fine and other languages are a better fit, but why is such environment not more famous?9 -
context: I'm sort of a self-deprecating guy and I really don't look for validation.
So, i decided to fuck it. I tried to provide the best decisions in terms of money-wise/biz-wise but apparently this guys rather choose what he believes is best for the code... (he knows shit of coding and that's coming from someone who is not a software engineer but rather a physicist who happens to code).
So, now i let him make all decisions. no opinion from me. a few things are going to shit because of him... fuck it. i had it. as long as I get paid. fuck him.
this is probably common... sorry for the rant.7 -
Last week I wired up my home network (including custom modem and routers) myself, because the stuff my ISP wanted me to use was garbage.
Luckily Germany has "router-freedom" so ISPs are not allowed to force us to use their device to dial into the network.
I did everything myself, because the 'technicians' they kept sending me were just idiots who didn't know anything, considering the highly paid job they are doing. Usually they told me, to get the device from my ISP, because my "Router" (actually a business grade, standalone Modem by Cisco, to feed my Router) didn't even have WiFi ( lol ). Also all Technicians didn't arrive at the agreed date but at some other time. I wasn't able to wait any longer.
So I did it myself.
Consider me something more like a student of theoretical computer science. Not actually supposed to be experienced with hardware stuff.
The ISP is serving me with a DOCSIS 3.0 Network based on the television cable network in my city. For some reason they are providing the internet-access to only one socket in the apartment, which has a rather uncommon "WICLIC" connector. After having trouble getting an adapter for WICLIC to common coaxial F-Connectors (used by every DOCSIS-Modem), I made one myself.
After setting up everything (not that hard, once the connectors fit) my modem told me, that, while I'm perfectly connected to the ISPs internal Network, I still can't access the internet.
So I called the ISP...
After getting ranted at, about that what I'm doing is illegal and only certified employees are allowed to do this and I will break more, than actually do good and that I can't just connect my own "Router" (again I needed to correct her: Modem) I hang up the phone.
Also she accused me of hacking their devices because I'm not supposed to see my IP address... (My Modem told me on its web interface. I didn't even need telnet for that.)
I went to the ISPs head office, told the first desk as many technical terms as I could remember and got forwarded to something like the main technician.
He was a really nice guy. The only sane and qualified person I dealt with at this company. He asked me for my Address and Device Model, I told him my MAC and last internal IP, I had seen and he activated my internet access within a minute.
We talked a while about the stupid connector that ISP is using in the homes and he gifted me some nicer adapters to connect my modem to the wall.
Why do ISPs hate their customers that much?2 -

For all of youse that ever wanted to try out Common Lisp and do not know where to start (but are interested in getting some knowledge of Common Lisp) I recommend two things:
As an introductory tutorial:
https://lisperati.com/casting.html/
And as your dev environment:
https://portacle.github.io/
Notice that the dev environment in question is Emacs, regardless of how you might feel about it as a text editor, i can recommend just going through the portacle help that gives you some basic starting points regarding editing. Learn about splitting buffers, evaluating the code you are typing in order for it to appear in the Common Lisp REPL (this one comes with an environment known as SLIME which is very popular in the Lisp world) as well as saving and editing your files.
Portacle is self contained inside of one single directory, so if you by any chance already have an Emacs environment then do not worry, Portacle will not touch any of that. I will admit that as far as I am concerned, Emacs will probably be the biggest hurdle for most people not used to it.
Can I use VS Code? Yes, yes you can, but I am not familiar with setting up a VSCode dev environment for Emacs, or any other environment hat comes close to the live environment that emacs provides for this?
Why the fuck should I try Common Lisp or any Lisp for that matter? You do not have to, I happen to like it a lot and have built applications at work with a different dialect of Lisp known as Clojure which runs in the JVM, do I recommend it? Yeah I do, I love functional programming, Clojure is pretty pure on that (not haskell level imo though, but I am not using Haskell for anything other than academic purposes) and with clojure you get the entire repertoire of Java libraries at your disposal. Moving to Clojure was cake coming from Common Lisp.
Why Common Lisp then if you used Clojure in prod? Mostly historical reasons, I want to just let people know that ANSI Common Lisp has a lot of good things going for it, I selected Clojure since I already knew what I needed from the JVM, and parallelism and concurrency are baked into Clojure, which was a priority. While I could have done the same thing in Common Lisp, I wanted to turn in a deliverable as quickly as possible rather than building the entire thing by myself which would have taken longer (had one week)
Am I getting something out of learning Common Lisp? Depends on you, I am not bringing about the whole "it opens your mind" deal with Lisp dialects as most other people do inside of the community, although I did experience new perspectives as to what programming and a programming language could do, and had fun doing it, maybe you will as well.
Does Lisp stands for Lots of Irritating Superfluous Parentheses or Los in stupid parentheses? Yes, also for Lost of Insidious Silly Parentheses and Lisp is Perfect, use paredit (comes with Portacle) also, Lisp stands for Lisp Is Perfect. None of that List Processing bs, any other definition will do.
Are there any other books? Yes, the famous online text Practical Common Lisp can be easily read online for free, I would recommend the Lisperati tutorial first to get a feel for it since PCL demands more tedious study. There is also Common Lisp a gentle introduction. If you want to go the Clojure route try Clojure for the brave and true.
What about Scheme and the Structure and Interpretation of Computer Programs? Too academic for my taste, and if in Common Lisp you have to do a lot of things on your own, Scheme is a whole other beast. Simple and beautiful really, but I go for practical in terms of Lisp, thus I prefer Common Lisp.
how did you start with Lisp?
I was stupid and thought I should start with it after a failed attempt at learning C++, then Java, and then Javascript when I started programming years ago. I was overwhelmed, but I continued. Then I moved to other things. But always kept Common Lisp close to heart. I am also heavy into A.I, Lisp has a history there and it is used in a lot of new and sort of unknown projects dealing with Knowledge Reasoning and representation. It is also Alien tech that contains many things that just seem super interesting to me such as treating code as data and data as code (back-quoting, macros etc)
I need some inspiration man......show me something? Sure, look for a game called Kandria in youtube, the creator, Shimera (Nicolas Hafner) is an absolute genius in the world of Lisp and a true inspiration. He coded the game in Common Lisp, he is also the person behind portacle. If that were not enough, he might very well also be Shirakumo, another prominent member of the Common Lisp Community.
Ok, you got me, what is the first thing in common lisp that I should try after I install the portacle environment? go to the repl and evaluate this:
(+ 0.1 0.2)
Watch in awe at what you get.
In the truest and original sense of the phrase (MIT based) "happy hacking!"9 -
The world of SSO (Single sign on) it's a real shit.
At start I tought its a pretty common feature that lots of people want, so there should be a lot of open source options for making a server and client libraries.
So far I've only found to libraries, written in java with a fucking big book instead of a simple documentation with billions of options and features but without a fucking guide to get it running and connect with a database.
It's that hard to write an easy manual with the steps to get it running instead a giant book with million's of technical terms and architectural details?1 -
!rant just a question. Sorry in advance for the long post.
I've been working in IT in Windows infrastructure and networking side of things for my entire career (5years) and recently was hired for a role working with AWS.
We use Macs and we use *nix distros for days. I've only ever dabbled for 'funsies' before with Linux because every previous job I held was a Windows house and f*** all else.
I'm just wondering if anyone here might have some insights as to a great way to learn the Linux environment and to learn it the right way. I'm not the best Windows admin ever and will never claim to be, but I have seen stuff that other people have done that makes me want to swing a brick at someone's head. And I feel that with all of the setup wizards and the "We'll just do it for you." approach that Windows has used since forever it allowed enough wiggle room for people that didn't know what they were doing to f*** sh*t up royally. I'm not familiar enough with Linux to know if this is also a common problem. I know that having literal full-access to every file in your OS can cause a n00b like myself to mess up royal, thus the question about learning Linux the right way.
I vaguely understand the organization of the folders and file structure within Linux, and I know some very basic commands.
sudo rm -rf /*
Just kidding
But All of my co-workers at my new job are like mighty oaks of knowledge while I'm a tiny sapling. And at times I've been intimidated by how little I know, but equally motivated to try and play catch-up.
In addition to all of this, I really want to start learning how to program. I've tried learning multiple times from places like codecademy.com, YouTube tutorials, and codeschool.com but I feel like I'm missing the lesson that explains why to use a certain operation instead of another. Example: if/else in lieu of a switch.
I'm also failing to get the concept of syntax in certain languages I've tried before. Java comes to mind real fast.
The first language I tried teaching myself was C++ from YouTube. I ended up having a fever dream that night about coding and woke up in a cold sweat. Literally, like brain overload or something. I was watching tutorials for like 9 hours straight.
Does anyone know of a training resource that will explain, in terms a 5 year old would understand, what the code is doing and why? I really want to learn but I'm starting to lose steam cause I'm just not getting it.
Thank you in advance for any tips guys and gals. I really appreciate it. Sorry for the ridiculously long questions.5 -
So in my org, as far as I can see, senior engineers and normal engineers do about the same amount of work, and the senior engineer is useful at PBRs for bringing up tech points that other engineers might not know about due to lack of experience. Is this a common thing across the whole software business? In terms of responsibilities, I’m seeing pretty much the same amount, don’t wanna sound arrogant here but we never task work etc based on seniority which I like but just want to know if it’s common6

I'm working in a company as fullstack developer where we use Angular for frontend, and C# for backend, lots of cool things to learn, for instance, we need a way to dynamically load forms controlled from backend, not something that is common but interesting to solve.
However, I feel sometimes I don't belong here, not because the things we do is not fun, it's just that most of the developers have very little experience with building web apps. And this means I don't develop as much as I wanted towards the web path.
I was informed before starting here, that 3 web devs would be hired including me, and they have experience with Angular. After I was hired, one guy decided to jump off (skilled web dev), and it was only me and the other guy left. The other guy has little experience with the web in general, but extremely good in terms of architecture and programming patterns in C#.
The salary is fine, but it's just I don't feel the growth I was expecting. Most of the things I learn on my own, which I've done in the past years.
I'm thinking that if I work in a place with skilled web devs, I'll learn lots of great things which I don't have to search all the time.3 -
I have a question, but first some background. When I got my first job, it wasn't clear cut what I would do, but I ended up doing frontend. I really liked doing frontend, so I continued doing so and I still do to this day. I even work alongside designers in a design studio, so I feel very much like a frontend developer.
Obviously, the term "frontend" these days implies someone, in some ways, writing a web, mobile or desktop app using javascript. For me, frontend is also about stuff like accessibility, design, code delivery, and understanding the end-users and the designers that may have prototyped something for you.
I have not been active in any other dev communities than this place, but it seems to me like a frontend developer is pretty much the lowest common denominator ( I guess in terms of skills). If I am right, I do not know why, which is why I'm hoping someone could explain.9 -
Over the last few years, i explored the DMZ between dev's world and customer's world. It is a DMZ where both are in contact, ones trying to convince the others to invest on them, and i was just shocked !
People are so stupid and Elitist, they think that an ultimate great godly dev exist !
It is totally fake for sure, they image that a good have to know absolutely everything about all the damn languages (while everyone googles every single comment received, even the most "advanced" dev)
I am shocked to see how people apply their everyday life metrics to the dev's world, i mean, there are a lot of devs around, everyone coding his way to self-improvement, we are all different, we have trends, and we can definitly define groups of developers and types of developers, but people think that a good dev have to come from silicon valley ! Does it means that a dev coming from Vladivostok is less worth ? even he is more dynamic in his approach ? even if he yields more results in terms of solutions ? (SV devs tends to be too much technical, while russians tends to be in the heart of action directly).
Common people shouldn't mess with what they know nothing about, and stay at their "Consumer" position. -
Random thoughts on more out of the box tools/environments.
Subject: Pharo
Some time ago I had shown one of my coworkers about Pharo and he quickly got the main idea behind it but mentioned how he didn't like the idea of leaving behind his text editor to deal with source code.
Some time last week I showed the dude some cool 3d animations you can do with Pharo while simultaneously manipulating the code to change them in real time. Now that caught his attention particularly and he decided he wanted to know more about the language but in particular the benefits of fucking around with an image based environment rather than a file based.
Both of us reached the conclusion that image based makes file based dev enviroments seem quaint in comparison, but estimated that it was nothing more than a sentiment rather than a fact.
We then considered what could be the advantage/disadvantages of such environments but I couldn't come up with anything other than the system not having something like Vim or VS Code or whatever which people love, but that it makes up for it with some of the craziest IDE tools I had ever seen. Plugins in this case act like source code repos that you can download and activate into your workflow in what feels something similar to VS Code being extended via plugins written in JS, and since the GUI is maleable as it is(because everything is basically just subsets of morp h windows) then extending functionality becomes so intuitive that its funny
Whereas with Emacs(for example) you have to really grind your gears with Elisp or Vimscript in Vim etc etc, with Pharo your plugin system is basicall you just adding classes that will convert your OS looking IDE into something else.
Because of how light the vm machine is, portability is a non issue, and passing pharo programs arround is not like installing Java in which you need the JVM.
Source code versioning, very important, already integrated into every live environment and can be extended to do pushes through simple key bindings with no hassle.
I dunno, I just feel that the tool is too good to be true. I keep trying to push limits into it but thus far I have found: data visualization and image modeling to work fine, web development with Teapot to be a cakewalk and work fine, therr are even packages for Arduino development.
I think its biggest con would be the image based system, but would really need to look into how this is bad by any reason other than "aww man I want vim!" since apparently some psychos already made Emacs and VS code packages for interfacing with Pharo source trees.
Embedded is certainly out of the question for any real project since its garbage collected and not the most performant cookie in the jar.
For Data science I can see some future, seems just as intuitive and interesting as a Jupyter Notebook actually, but the process can't and will not be the same since I still don't know of a way to save playground snippets unless you literally create classes for it, in which case every model you build gets saved inside of an object, sounds possible but, strange since it is not a the most common workflow in jupyter.
Some of the environment is sometimes glitchy, but it does have continuos development and have not found many hassles.
There is a biased factor from my side: I seem to be wired to understand the syntax and simple object model better than in other languages. To me this feels natural as if I was just writing ideas rather than code, mostly because I feel that there really ain't much in terms of syntax, the language gets out of my way and the IDE feels like the most intuitive environment in the world to me. I can see why some people would find it REALLY weird of counterintuitive tho.
Guess I really am a simple dude. -
Is it just me or are books on algorithms split between being too simplistic and being too detailed to be practical. I read Donald Knuth's book "The Art of Computer Programming Vol.1" read about 10% of it , which is like 3 chapters. I really enjoyed those chapters, Knuth's is such a genius but then the rest of the book was so complicated that the introduction and definition of terms was longer than some whole chapters in the same book. I decided to look for another, found a really good one, but it was analyzing algorithms in Java, sigh, I hardly code in Java so it was exactly easy for me to follow when he keeps mentioning the "comparable" attribute on sorting algorithms. I then got another really followed it till the keep on referencing indicator variables, I had read 3 books now and had not had of these indicator variables. Am sure they are not that common in the Computer Science literature so I was left wondering why I had to learn to analyze code with indicator variables though it was not a standardized in the "Computer Culture" would I be the only one who does this?.. I hence gave up on learning algorithms till I got that book that was just right for me5

Online investment schemes have become increasingly popular, promising high returns with minimal effort. However, it is crucial to be aware of the significant risks associated with these schemes. Many online investment platforms, particularly those in the cryptocurrency space, operate with limited regulation and oversight, which makes them fertile ground for scams and fraudulent activities. Recent personal experiences have underscored these risks, highlighting the importance of vigilance and due diligence when engaging in online investments. My unfortunate journey began with a company called "CryptoTX," which presented itself as a legitimate crypt0currency trading platform. Initially, I was drawn in by the promise of lucrative returns and was reassured by my assigned account manager, Sarah Malone. She portrayed CryptoTX as a reputable firm with a track record of success. During our interactions, I mentioned my previous experience with another online trading platform, "Click’s Dealer." I had encountered significant issues with Click’s Dealer, and Sarah Malone assured me that it was a scam, further reinforcing my trust in CryptoTX. I started with an initial investment of $1,000, which, at first, seemed promising. I saw some trades yielding returns and even experienced what appeared to be substantial profits. Encouraged by these early successes, I decided to invest more, eventually committing a total of $180,000. However, this initial optimism soon turned into a nightmare. The tipping point came when I began to notice inconsistencies in the information provided by Sarah Malone. Each time I was contacted, I was urged to invest more money to cover "bad trades" or to capitalize on supposed new opportunities. Despite my growing concerns, I continued to follow their advice, largely due to the pressure exerted by the account manager and the desire to recover my previous losses. It became clear that CryptoTX promises were unfounded. My investments, which had initially shown some potential for profit, quickly dwindled. I found myself losing all of my hard-earned savings, amounting to a staggering $180,000. This sum represented my life savings, intended to secure my financial future and support me in retirement. The financial loss was devastating, not only due to the amount but also because of the emotional and psychological toll it took on me. In the aftermath of this experience, I realized that the terms and conditions I had agreed to likely included clauses that absolve CryptoTX of responsibility for investment losses. Many online investment schemes use such disclaimers to shield themselves from liability, arguing that investment inherently involves risk and that they cannot guarantee returns. This legal shield makes it challenging to hold them accountable, despite their misleading practices. Determined to recover my lost funds, I explored various avenues for redress. During my search, I discovered GRAYWARE TECH SERVICES, a consultancy and recovery firm that specializes in helping victims of online investment fraud. The firm had received positive reviews for its success in assisting individuals who had been defrauded by unregulated brokers. Deciding to give them a chance, I contacted GRAYWARE TECH SERVICES. Engaging with GRAYWARE TECH SERVICES turned out to be one of the best decisions I made. Their team provided expert guidance and support, working tirelessly to investigate my case and facilitate the recovery of my funds. Through their dedicated efforts, I was able to retrieve a significant portion of my losses, which was a tremendous relief. This experience has underscored the importance of exercising caution when dealing with online investment schemes. Many of these platforms operate with minimal regulation and oversight, making them ripe for exploitation. It is crucial to conduct thorough research before committing funds, be wary of platforms that promise guaranteed returns, and understand the terms and conditions associated with any investment. while the online investment landscape can offer lucrative opportunities, it is fraught with risks and potential pitfalls. Scammers and fraudulent schemes are prevalent, and it is essential to be proactive in protecting oneself from such threats. Educate yourself about common warning signs of fraud, seek professional advice if needed, and remain vigilant to safeguard your financial well-being.
