I want a ThinQ G7 and for some reason it is $200 cheaper to buy stock than from the T-mobile store. Other than swapping SIM cards would I need to do anything else to make it work?

Is this a good value/dollar phone? I can afford a more expensive one but I don't do much other than google maps, meetup and bumble

Did any of you programmers learn how to program from a trade/vocational school? If you didn't, but managed to be hired (for your programming skills) anyways, what exactly was your method of learning? Don't answer if you're gonna say college, that's an easy answer. If you didn't go to trade school nor college then I'd assume you learned using programming books. Go ahead and suggest some if you wish, but that isn't the primary concern at the moment. Did you keep a GitHub portfolio?

Another question, if I may; if you did go to a trade school, how exactly did you find it? I'm in the market for one, myself, but haven't actually found any, and google seems to confuse trade schools with community colleges and actual universities, which I want no part of.

I went he traditional route with a B.S. in Computer Science and Engineering. Most top tier jobs won't even consider you without one.

However if you're looking to just be a niche programmer, you can just learn on the job and with books. For books, I like the Pragmatic Programmer series.



I've been looking at some books recently, even considering buying one on paper. It bothers me a bit that some these books focus mainly on specific libraries (scikit-learn etc). What's the chance that these will still be useful in the way they were printed 2-3 years ago in the future?

I've been considering getting the 2nd edition of this one which is due to come out in may http://shop.oreilly.com/product/0636920033400.do




Why is it then that only a small fraction of US students are going into apprenticeships or tradeschools if it's apparently not looked down upon? In european (especially german speaking) countries the students going into vocational education outnumber those who go to university.



Because they fell for the idea that everyone needs a college degree to work at even McDonalds.



If you find it useful at any given time, it will likely have been worth it to buy and read. The area you're looking into is pretty stable too, so I wouldn't worry too much about the knowledge becoming obsolete.

For those who don't know, LynxChan is a new chan engine I have been developing for the past 4 years or so.

Today I started 2.2 beta. It's main feature is the comeback of archives. Not only threads can be archived manually, but also limits for replies can be set for threads to be archived automatically after these limits are passed and the thread is pruned.

On a smaller scale and a more technical aspect was the optimization of ram usage. It should have use 80% to 75% less ram. Boot times have been improved too. And the json api have been merged into the form api too, which should make for a more consolidated api.

What about no? Botnet captcha is only easy to solve, if you use botnet browser and you're logged in to botnet.

Also if the captcha is hard to solve even for a human, then it's a good captcha, because only a bot as good as a human will solve it. I fail about 1/10 captchas, so it's fine.



at least i can see that its a traffic light. here the letters are often covered by random lines and are mixed case so you cant know what the letter thats covered by the line actually is. the letter could be a l but it could also be a I

Why the fuck do retards want a desktop operating system on a shitty mobile touchscreen device? I'd rather have an OS that's specifically designed to be low CPU usage and otherwise designed for mobile usage in terms of energy efficiency and UI design.



>Why the fuck do retards want a desktop operating system on a shitty mobile touchscreen device?

Implying GNU/Linux can't do that. Implying there are no embedded distributions already. Are you using Windows or Ubuntu? Don't you know you can remove/replace a lot of unnecessary packages and that you're not forced to use a certain UI?

>I'd rather have an OS that's specifically designed to be low CPU usage and otherwise designed for mobile usage in terms of energy efficiency and UI design.

Name one. iOS is modified BSD - a desktop/server system, Android uses the Linux kernela desktop/server kernel/system, guess that's what you mean as an "operating system", Windows phone is probably a modified Windows system too.



gnome was designed for touch devices but they forgot that resource usage matters on such devices


>muh Linux smartphones

>Android phones already exist

This is what you open source cucks asked for. Linux with a pretty label backed by huge corporations who data mine everything you do. As for Librem and other "FOSS-friendly projects that are trans inclusive and cost $900 bucks in cash", you are getting ripped off and they will fail tragically. Prove me wrong.



many people buy very expensive phones these days. they just dont pay it at once so they dont understand how much they are actually paying. most would not even have the money that would be needed if you want to pay it fully immediately.

Can Linus be saved?

We don't know exactly what happened to him (although one could theorize it might have had something to do with his feminist daughter and the trannies at tech companies) and he hasn't appeared in any public space, conference or video after his cucked "temporary retreat to think about things" (has he? I didn't see anything so I don't know for sure). I don't know exactly where he stands on now other than him saying he's not going to go on his classic rants anymore.

The rants were important. He was stern and determined, and his rudeness was necessary to impose something approaching quality to kernel development. He had strong stances against breaking user space, and specially on blaming someone else for your bad code. Sure, he could still make a "softer" rant about it now, but will it have the same impact as before? Will he even make another rant anymore?

I wish we could at least know what the hell happened to him that made him do what he did, and allow that one Coraline tranny to infect the kernel with his smelly CoC


Found a video, interviewed by a Pajeet. I think this is it.



Linus is ready to retire. He's ready to hand over Linux leadership to his most trusted subordinates.



He's grown tired.

Humans have a short lifespan, and at some point, if they don't have a direct, trustworthy heir, then everything they have built is sent to ruin and they are too tired and old and exhausted from the fight of life to prevent it from happening.

Given how fervent linuxers have been since the beginning, one would think they would rabidly destroy any outside element that is attempting to subvert the masterwork.



>Can Linus be saved?

Yes he must only tell people publicly, that Linux is just a kernel and GNU/Linux is the system.


doesnt he just accept things to the git and screech on the mailing lists now or does he actually still contribute code?

Honestly just adding more philosophers and neuroscientists and cognitive scientists into AI research would be way more practical. That's the actual issue at hand, providing inspiration to where programmers and mathematicians should focus on algorithm development to capture more elements of cognition. The only diversity that's relevant is diversity of ideas spanning from a range of fields relating to intelligence itself.

On another note, most of the recognition problems fix themselves if an AI is given the capacity to self-regulate visual perception by context for learning. That means the ability to focus attention on certain types of abstract data, while filtering out all the rest for learning/executing sub tasks contextually. Then with that data, it can be used to meta-learn how to compare and relate abstract groups of sub-tasks into concepts. The result is that it'll eventually learn to recognize all faces by figuring out which sub-tasks are useful for facial recognition and how common abstract concepts are present in all human faces.

You'd think it would be more useful to figure out how an AI can deal with limited data, and reason for itself to recognize similar things instead. That's what really pisses me off about the article, it offers absolutely nothing useful to address their own concerns and poses a serious threat to AI research if taken seriously.


these people are hell bent on making sure that any AI they develop is completely useless

lmao China is gonna win the AI wars so hard



>lmao China is gonna win the AI wars so hard

The problem with AI and machine learning algorithms are that they tend to break when you have to censor them as shown in this threads example. China is a lot more strict then the USA when it comes to censorship so how dare I ask are they going to win if they can't actually apply it outside of maybe military applications which the USA is already ahead of them regardless.



>chinese AI maybe limited about muh democracy and muh tiananmen square

>western AI not even allowed to recognize people by race or gender



Won't matter how either one develops it, as it gets more towards general intelligence it'll always have the ability to discriminate no matter what. It's hard-wired into intelligence itself.

After all it won't be able to rapidly learn in real-time if it cannot discriminate on what information it should focus on at a given moment (serving as a basis for meta-learning). It becomes more apparent when it's learning how to combine knowledge to solve more complex problems as it experiences them.

Current AI applications suffer dearly because outside the bounds of training they're absolutely useless. Eventually they would be forced to overcome that problem if they want to expand real-world applications of AI.

I'm going to be doing a product design paper next semester, in which I have the lion's share of 6 months to make a half decent prototype then demonstrate it at the end. I have the knowledge and resources (CnC machines, 3D printer, CAD experience, etc) to make a decent variety of things. The problem is coming up with something that isn't shit.

Ideas I trashed are:

Supercapacitor powered toy car - Can charge fast as all heck then romp around for maybe a minute or two, could be a good toy for kids since it wouldn't need to spend ages charging.

Problems - Every man and his dog are making supercapacitor powered toys on Youtube, and this would have fairly limited scope for design process write-ups and design refinement, if I really wanted to this could be done in a week or two.


Problems - No real advantages compared to a firearm, probably won't be allowed to make a bootleg weapon, horrible idea.

HUD Diving Mask - A diving mask with depth, gas pressure, etc displayed in a HUD for the user, a few of these have being produced commercially but none have really been successful for various reasons.

Problems - OLED technology isn't quite there in regards to embedding a screen in the lens, furthermore even if it was my place of study lacks the tools for me to embed an OLED screen in a lens and embed other circuitry in silicone (for a half decent prototype I'd basically need to manufacture a diving mask as well).

In short I'm looking for a half decent idea that isn't pathetic/useless or way too ambitious for a 6 month project with relatively limited tools at my disposal.

Feel free to use this thread if you're in the same boat or just want to do a project for fun.


Make a website where you can combine multiple rss feeds into one.



Asset tracking for a warehouse:

Have little battery powered RF transmitters that you can attach like a paper clip to the top flaps of boxes. Have the transmitters send a uuid occasionally. Have a few beacons in known positions to receive the signal and triangulate the position for each tag. Display.

You could do write-ups about battery power/update frequency trade offs, distance/signal frequency/battery power trade offs (consider environment, large metal shelves + the content of the boxes might block the signal), all sorts of shit.

I've been meaning to make this for a while now, but I've always gotten busy with other less-important shit. We should have occasional "idea garage sale" threads like >>>/agdg/ does.


build a 1000 wat infrared laser to burn down buildings in minecraft



This isn't half bad, not really my area of interest but I could see it being a fairly enjoyable project. I'll keep it in mind.

>canvas fingerprinting

This shit is a privacy nightmare. Every website you visit can generate a hash which is unique to your device. Yet, spoofing it makes you even more unique.

How do we defeat this sort of tracking ? Tor browser has a feature which sends a blank canvas, but it's not a sufficient solution for everyday browsing

Last time I used that plugin it gave you popups when it blocked canvases and required you to manually type addresses into a whitelist file. The screenshots on the current page look different though so maybe it's changed.



>whats a canvas and why would you ever need/want that?

That's a shit on which you can draw with webgl, etc.




It lets you draw things onto an image and use hardware acceleration, you can even make 3D games with it. Besides browser games, the only valid usage I know of is displaying rotateable 3D models/data on the webpage.



Useless bloat. Firefox has an about:config option to spoof/hide canvas.



privacy.resistFingerprinting = true




so its nothing that i use. last time i played a game in a browser was over 10 years ago and it used flash player. i really use the browser for accessing text and normal pictures so security & bug fixes are the only reason to ever update

Is taking steps to stay anonymous online ultimately futile?

Running open source browsers with anti ad and tracking features at least guarantee big corporations can't as easily gather data on you but this is about where the ease ends.

For example, lets say your next step is downloading software to further configure your computer for privacy, like email clients, torrent clients, virtual machines, misc productivity tools, etc. You download these through Tor but your ISP still knows you're connecting to Tor, so how the fuck am I supposed to download software to evade prying eyes when those prying eyes will, by my download activity, be able to determine I am trying to evade them and probably take steps to do le sneaky shit. Obviously, you'd use a tustworthy and transparent VPN along with Tor, but YOU CAN'T GET THE FUCKING VPN COMPLETELY ANONYMOUSLY EITHER. You can pay with crypto but the steps you take to buy crypto will be known so they know you; 1. are into crypto 2. used it to purchase a VPN. Yeah, maybe you're off the grid after these two steps by this time you've probably done so much internet research on this they've got a nice little log and can get a good idea of what you're trying to do and why. They know XYZ user purchased a VPN with crypto and will keep tabs on you.

Am I supposed to get a burner laptop and configure it somewhere else besides my own house, load all the installers onto an encrypted usb, and load it onto my desired computer? If I do that, who can still see what software I run on my computer? What the FUCK

I was pondering the shortcomings of some of the major resources to obtain information on the internet, and I think I have a solution. Here are the problems:

1. No financial incentive to share media

2. Copyright laws pose major risks to hosters so they have to jump through extreme leap holes like being hosted in russia

3. There is not a one stop shop for information. You can spend months trying to find one piece of material that interests you.

How do you solve this? Decentralization. How do you achieve that? Some sort of system that provides the anonymity of Tor with the shared computing resources afforded with BitTorrent. The best way to provide the financial incentive is through something similar to a crypto currency that provides small bounties for every file that you upload. The bounty must somehow be gauged for the value of your uploads in order to prevent spam and the associated problems. As far as the last problem is concerned, there should be some sort of scraper that matches files with the content therein. What are your thoughts? Is it too much of a pipe dream?



Perhaps Freenet is a better analogy than Tor. Tor is not decentralized in a lot of ways. Hosts can be nabbed simply because they hold the keys to the information. Whereas Freenet pushes the brunt of the risk onto the downloader. So how do you reconcile the downloader/uploader risk? Make it nearly impossible to track either one. Perhaps the data redundancy strategies of Freenet can be improved to create so much noise that it is completely impossible to trace either hosts or clients.

How come communists try to appropriate free software and open source philosophy when they are actually the opposite? Are they that clueless about what they defend or are they just trying to pull as many retards as possible on, even if by lies and deceit? I mean, of course (((the ones behind communism))) are trying to do just that so that they can rule over, but even the would be underclass retarded drone are sinking that low?
