Just ruined a clogged .2mm nozzle; Best way to unclog these?

3D printing news - 17 min 44 sec ago

Man, this has been a rough week for me on 3D printing. First I get a ball-o-plastic on my heating end from leaving a print alone for 9 hours, and then I end up with a clogged .2mm nozzle (my only one), and all my attempts to fix it failed and I ended up over-boring it with the tiny drill bit that came with my printer.

So, what is the best way to clean these without destroying them? I tried doing the atomic pull method, I tried heating the nozzle to very-high temperatures--no dice.

Any advice would be appreciated!

Book recommendation for algorithms

Learn Programming - 58 min 44 sec ago

Hi, I've been studying web programming on my own for a while and have been feeling a need to get to know more basics and lower level things about computers and computer science. So I started Harvards CS50 course. Now I've found a book called The algorithm design manual by Steven Skiena. Been reading it a few nights but I find it too hard to understand since I lack some mathematics background. My question is, could you recommend a book for algorithms and data structures and all that is easier to grasp, easier to get the basic ideas behind? Thanks!

edit: 'conputer'

Is Udacity worth it?

Learn Programming - 1 hour 45 min ago

I read that there's a lot of pushback against codecademy (that it doesn't really challenge you or teach you to think critically).

I just signed up for the Beginners Android course on Udacity. Considering how much it costs, is it worth it? Will I learn something beneficial?

I'm not expecting a job, but I'm hoping this is one of many correct steps towards that goal.

USA College Student - Cheapest laptop that can run Ableton Suite, just a decent laptop

  • Total budget and country of purchase: USA and total budget is around 350, but cheaper options are preferred, want to spend as little as possible.

  • Do you prefer a 2 in 1 form factor, good battery life or best specifications for the money? Pick or include any that apply. 2 in 1 is completely unnecessary. Decent battery life is preferred, but I mainly only use my laptop for presentations, writing, and music production.

  • How important is weight and thinness to you? Minimal importance. If it fits in a Jansport backpack I'm happy.

  • Which OS do you require? Windows, Mac, Chrome OS, Linux. I'm most comfortable with Windows.

  • Do you have a preferred screen size? If indifferent, put N/A. Average sized screen preferred. Tiny screens are off the table. I wear glasses.

  • Are you doing any CAD/video editing/photo editing/gaming? List which programs/games you desire to run. Ableton music production software. It doesn't need to run it 100% smoothly with the best crispest sounding features as I'm still a beginner with it and will eventually be upgrading my laptop.

  • If you're gaming, do you have certain games you want to play? At what settings and FPS do you want? N/A

  • Any specific requirements such as good keyboard, reliable build quality, touch-screen, finger-print reader, optical drive or good input devices (keyboard/touchpad)? I don't want it to break if it falls once, but not expecting military grade. If the sides get chips on them or scratches that's perfectly fine. I like clicky keyboards if that makes any sense. I loath Mac trackpads. Lenovo trackpads are alright if that makes any sense. Not sure what makes trackpads different but some work better than others. I dislike very large trackpads. Fingerprint reader would be awesome. I've gotten so used to them. Not necessary though if it will shave off some more cash. I'd like to be able to plug a mic and headphones into it.

  • Leave any finishing thoughts here that you may feel are necessary and beneficial to the discussion. This is mostly a transitional laptop. I'm using a loaned one currently and I'm in need of something that will let me keep up with my music production hobby but is decent for keeping me organized for when I get my first job out of college. I'll be saving up for a better laptop but if I can get something cheap that runs microsoft office and Ableton I'll be happy.

Query regarding seeds used during random number generation

For generating random (pseudo random) numbers such that every time the program is executed, the same random number is generated, we use seed.

Example (python code):

import random random.seed(123) print(random.randInt(0, 10)) print(random.randInt(0, 10)) print(random.randInt(0, 10))

This code will generate the same random number sequence everytime the program is executed.

My question is:

Can there exist two seed values which generate the same random number sequences?

Also, given 'n' sequentially generated random numbers, can we calculate the original seed?!

I found a website with an extremely high quality free catalog of Design patterns.

Learn Programming - 2 hours 44 min ago

It's called Refactoring Guru

It has detailed UML diagrams, explanations of use cases, implementation details, and best fits, and psuedocode with a nice interface that is mobile friendly. I have not tried the Refactoring course advertised and can't vouch for the quality of that, but so far this is the best resource I have found for learning design patterns.

* **Total budget and country of purchase:** $700-$800 US * **Do you prefer a 2 in 1 form factor, good battery life or best specifications for the money? Pick or include any that apply.** Ideally, I'm looking for a laptop that I can use a pen on. However, if a laptop isn't available within my price range with that feature, I'm okay without it and go with the best specifications. * **How important is weight and thinness to you?** Not important * **Which OS do you require? Windows, Mac, Chrome OS, Linux.** Windows * **Do you have a preferred screen size? If indifferent, put N/A.** N/A * **Are you doing any CAD/video editing/photo editing/gaming? List which programs/games you desire to run.** Need to be able to run Adobe Creative Cloud Suite, most importantly Photoshop, InDesign, and Illustrator. I rarely use Premiere Pro, but only because my current laptop isn't able to properly run it. I currently do very light gaming, not planning to play anything on it's highest settings. * **If you're gaming, do you have certain games you want to play? At what settings and FPS do you want?** Would want to casually play games at medium settings, but not a priority feature I need. * **Any specific requirements such as good keyboard, reliable build quality, touch-screen, finger-print reader, optical drive or good input devices (keyboard/touchpad)?** Would like a laptop with a good display that would allow me to best create graphic designs. * **Leave any finishing thoughts here that you may feel are necessary and beneficial to the discussion.** The major I'm studying at school requires me to do a lot of graphic design so I'm looking for something that will help me create those designs without having to worry about not being able to complete assignments and projects because my laptop can't handle the programs I'm using.

Looking for budget, portable, libre laptop

  • Total budget and country of purchase: $700 or less CAD (Canadian Dollars)

  • Do you prefer a 2 in 1 form factor, good battery life or best specifications for the money? Pick or include any that apply. I will need a decent battery life, at least 5 hours

  • How important is weight and thinness to you? Considering I will probably get recommendations for really old laptops, I am not expecting a super thin laptop. As long as it can fit in a bag and isn't too heavy, I can deal with it.

  • Which OS do you require? Windows, Mac, Chrome OS, Linux. It is very important that the laptop is compatible with Linux. I haven't decided what distribution I will use, but as of now Kubuntu is my favorite.

  • Do you have a preferred screen size? If indifferent, put N/A. As long as it's between 13.3" and 15.6" I will deal with it. 14" would definitely be preferred but considering the other requirements I want to try to be loose on everything else. I also want the screen resolution to be decent. I am not expecting to find a 1080p laptop, but its resolution must be above 720p.

  • Are you doing any CAD/video editing/photo editing/gaming? List which programs/games you desire to run. I will not be gaming or video editing on this computer. I plan to use it strictly for browsing and P2P related programs. It's also important the laptop can enter ad-hoc network mode, however I am unsure if this is a software thing or a hardware thing.

  • If you're gaming, do you have certain games you want to play? At what settings and FPS do you want? N/A

  • Any specific requirements such as good keyboard, reliable build quality, touch-screen, finger-print reader, optical drive or good input devices (keyboard/touchpad)? The laptop must have USB ports, and it is much preferred least 1 USB 3.0 port. However this may not be possible to find again because of other requirements I will list later, but again it is much preferred. Besides that it must have at least 2 USB ports in general. It also must have a resolution above 720p as mentioned before.

  • Leave any finishing thoughts here that you may feel are necessary and beneficial to the discussion. Here is where it gets tricky. Basically, I need a laptop that does not have Intel's Management Engine, Active Management Technology, or AMD's Platform Security Processor. This is because I plan to use Libreboot, and it goes without saying that the laptop needs to be compatible with Libreboot. From what I've heard, Intel and AMD added ME/AMT/PSP in 2009, so any laptop 2008 and before should be fine.

  • Overview

I added an overview just to make sure there isn't any confusion in what I'm looking for.

  • Screen size must range between 13.3 and 15.6 inches

  • Must be compatible with Linux

  • Screen resolution must be above 720p

  • Laptop must be compatible with Libreboot and must not have Intel ME, Intel AMT, or AMD PSP

  • Laptop must not be insanely thick or heavy, I will be carrying this around.

  • Must include at least two USB ports

  • Not a must but it is much preferred the laptop has at least one USB 3.0 port

All help is appreciated
