Looking for a general-use laptop that will last me the majority of university (5 years)

I am going off to university next year and I am in need of a laptop. As I have never owned a laptop before I don't really know where to start looking for a good one that will last me a few years if not longer so any advice will be appreciated.

  • Total budget and country of purchase: $NZD1600 ($USD1070), New Zealand

  • Do you prefer a 2 in 1 form factor, good battery life or best specifications for the money? Pick or include any that apply. Good battery life and decent specs.

  • How important is weight and thinness to you? Very important. I will be walking 2km uphill virtually every day to get to my classes and I don't want to have to be lugging around a heavy ass laptop with me. 4 pounds or less is a requirement. Also the laptop has to be able to fit into my bag so the screen can not be over 14".

  • Which OS do you require? Windows, Mac, Chrome OS, Linux. Windows preferably.

  • Do you have a preferred screen size? If indifferent, put N/A. Nothing over 14" but otherwise I don't really care.

  • Are you doing any CAD/video editing/photo editing/gaming? List which programs/games you desire to run. Adobe photoshop and illustrator.

  • If you're gaming, do you have certain games you want to play? At what settings and FPS do you want? Being able to handle gaming is not a requirement but if the laptop can handle me playing The Sims (3 and/or 4) every now and again that would be nice.

  • Any specific requirements such as good keyboard, reliable build quality, touch-screen, finger-print reader, optical drive or good input devices (keyboard/touchpad)? Good keyboard. Reliable build quality. Good speakers/sound quality. Good input devices. Multiple USB ports and preferably a HDMI port too.

  • Leave any finishing thoughts here that you may feel are necessary and beneficial to the discussion. My university degree will require me to do lots of research and typing/essay writing so the laptop will need to be able to handle extensive web browsing and have an easy-to-type-on keyboard. I would like this laptop to last me at least 3 years but if it could last me the whole of university (5 years) that would be great, so it has to be super durable.

How do you deal with feelings of failure?

Learn Programming - Thu, 09/20/2018 - 21:33

I don't know if this is the correct forum for this but I just want to know. I'm 19 and currently working for minimum wage at a restaurant while also pursing a A.S. in Computer Programming. While going to school full time I also work on freecodecamp because I want to start freelance web development while still in college. I have been doing it for 4 months but despite my college courses and freecodecamp sometimes I feel like I can't master programming. I also feel a immense wave of inadequacy where I feel I won't be able to get a job or work in this field of work. How do you deal with this feeling of failure or inadequacy while trying to gain the skills to land your jobs?

Also I sometimes question whether I am doing enough work, is there something else I should be doing as well? I'm learning java and cyber security in my A.S. Classes plus I'm learning front end web development in freecodecamp, are there some youtube channels or something else I should work on to help me in my past.

Thanks to all who answer in advance.

Generic Computer Science Question

Learn Programming - Thu, 09/20/2018 - 21:32

I know this is "r/learnprogramming" but I have a computer science question and this seemed like the best place to ask it. How would one go about making a program that does something. Wait! I mean, take Chrome for example I know there isn't some built in function .getWebsiteandLoad("google.com") and even if there was how would someone program that function? Other than math and outputing words on a console using python or C++ I am at a loss how somone would make a computer do something other than math and cout.

How to remember many langs/syntax/concepts?

Learn Programming - Thu, 09/20/2018 - 21:17

Hello all. Was wanting to know what techniques you all use to remember multiple language syntax and concepts. I've been coding in multiple langs across: web, desktop & mobile. Some that I understand better than rest: vb, c#, c, python, html, css, php, js, windows batch, linux bash. Have been doing netsec & webapp sec for long time too and remember most stuff because honestly they're easier to get into once we become good. Just have to be updated on latest exploits/tools/techniques going on.

Problem: Problem comes when switching the languages or trying to learn new things. Have notices that there is a point to which I can keep things in my brain. After certain limit, I remember the logic properly, but regaining complete syntax memory becomes harder as more and more concepts & designs are learned.

Example: After working with c, python, vb, c# for certain time, it's becoming harder to regain memory of complete oop syntax of php. Even after viewing and making the same things again as practice, not everything remains in mind. The memory in previous lang fades away as other things in different langs are learned.

My solution: 1) Idk if you all do this, but I've started depending heavily on internet for making bigger projects for faster coding. I do know the logic, so I don't see a problem, but morally feel the guilt of not knowing everything. 2) Internet helps most times, but with a bit of coffee, it becomes easier to recall stuff faster. Too much coffee makes jittery thoughts and mood/motivation crash, so I stick with 1 cup in morning. 3) Usually take 6-7hrs sleep to recover body & mind.

If any of you have a better method or trick to recall everything, it's much appreciated.

Best Laptop Screen (for Photo Editing/Viewing) under $1500?

  • $1500, USA
  • Convertible form factor & battery life: NOT important.
  • Weight/slimness of laptop: NOT important.
  • Windows 10
  • 15.6" or larger screen strongly preferred; 17" is better than 15", but not essential (bigger the better, basically)
  • Photo Editing is priority (Gaming NOT important)
  • Backlit keyboard and SDXC Card reader desired
  • Direct retail from Best Buy, Wal-Mart, OfficeMax, or other retailers with storefronts and a reputation for strong customer support strongly preferred (if online: Manufacturers themselves, Amazon, B&H, and Adorama are okay if directly from them, not third party merchants like Antonline, for example, and Newegg is strictly out)

If $1500 excises most of the ideal options, expand to $2000. Just specify. These have been my primary reference resources used:

  1. https://www.notebookcheck.net/The-Best-Notebook-Displays-As-Reviewed-By-Notebookcheck.120541.0.html
  2. https://www.laptopmag.com/benchmarks/color-gamut ; https://www.laptopmag.com/benchmarks/resolution

\note: unfortunately Laptopmag has the same charts up for Color Gamut and Resolution-- I sent them a message, but it remains unfixed*

So far the Dell XPS 15 9570 has been the top recommendation, and appears to be the top option, with the ideal variants running between $1500-$2000. Right now I'm focused keenly on learning which screens are actually the best. MacBooks are phenomenal, but I need Windows.

Emphasis in determining "best" screen quality is on photo editing metrics like resolution, color reproduction, contrast, brightness, etc. Qualities desirable to gamers like refresh rates, response times, and input/display lag are not a concern. I understand processing power, and don't need help with other specs. My focus is really on seeking input about which screens in this budget range are the best in terms of display quality for photo editors.

These are the lines/models my research has indicated are ideal. Hope I'm on the right track:

  • Dell XPS 15 9570
  • Lenovo Thinkpad P71/P51
  • Lenovo Thinkpad P72s
  • Lenovo Thinkpad Yoga 920
  • Lenovo Thinkpad X1 Carbon*
  • Dell Precision 7730/7720/7530/7520
  • HP Zbook Studio G4
  • HP Zbook 15 G4
  • HP Elitebook 840 w/SureView display*

\Only 14" displays*

How am I doing? Which of these is best?

cmder questions on Windows. Help a noob out

Command Line - Thu, 09/20/2018 - 21:12

Just installed cmder after being unimpressed with GitBash. I just got a new Windows laptop.

I normally used iterm2 on Mac and LOVED it. Just got a Windows machine. I use Vim and Git heavily and just have some stupid questions regarding cmder.

  1. iterm2 on Mac starts INSTANTLY when I click the shortcut for the terminal. Cmder seems to take about two seconds to open up and get to where I can type. Yeah, this isn't the biggest deal, but it's annoying. I like things to be snappy. Is there anything I can do, or is it this way for everybody?

  2. How in the world do I switch to a new tab in cmder using the keyboard. For iterm2 I would just use cmd + shift + [ or cmd + shift + ]. This was extremely fast and fluid. What is the windows shortcut?

  3. How do I split my window into two panes USING keyboard shortcuts? In iterm it's just cmd + d to split vertically. Then I can easily swap between them.

  4. How do I get lists to wrap around the current window dimensions? iterm2 would always do this so I wouldn't have to scroll up. For ex, on cmder I can press "ls" and there's a giant list of shit that goes outside of the dimensions of the currently opened window. How can I make things wrap?

  5. How do I show HIDDEN files doing an ls? I DO NOT want to have to do ls -a everytime, I just want everything to show doing ls.

x-post from /r/sysadmin:

I usually have more computers/laptops available for a thing like that, but I have recently shipped them all to where I will be retiring in a few months (Philippines). Thank goodness I kept my Raspberry Pi here. I post this comment by using that computer.

Plus, granted a keyboard, mouse, TV, and HDMI cable.

[C++]How can I some space between the answer and menu driven program?

Learn Programming - Thu, 09/20/2018 - 21:04

https://ideone.com/uEG0ng

The program works fine but when one of the statements finishes the menu driven program pops up again with the answer to the statement right above it. Is there any way to get some separation between the answer and the menu?

Best gaming laptop under $700 that has a 15 inch or higher screen and also well built

My sister just received a 700 dollar gift and she always wanted a good gaming laptop.

She really doesn't want to spend all of her gift on just a computer, she wants to get one as affordable as possible, but if impossible, then what laptop would you suggest for her?

As with everyone else I need a laptop

Need a laptop for going back to university. I am from the UK so need to be able to get it over here.

I am doing engineering and would like to to be able to do these things.

CAD, run basic programs, word, excel, matlab, streaming, general procrastination.

Now specs wise I sort of know what I would like, similar to the laptop I am borrowing now, or better, but correct me if you feel otherwise.

I am borrowing a laptop from a friend the specs are as follows:

CPU Intel i7-4910MQ

16GB RAM

4GB Graphics card

Must have, I want it to run windows 10.

Budget I'm working with is £1,500. Wouldn't want to spend more than that.

Brands I have looked at are Lenovo & Dell, would not mind one of their machines. But am open to others.

Screen size prefer 17 inch but negotiable and is battery life is not a defining factor for me, Bigger is better but as with screen size I will always be near a plug.

Thank you guys for your help. I hope we find something good, for my sake

Is this laptop worth $209?

Hello everyone and thank you in advanced.

Would this laptop be worth grabbing for $209? https://www.bestbuy.com/site/dell-inspiron-15-6-laptop-intel-pentium-4gb-memory-500gb-hard-drive-black/6239210.p?skuId=6239210

I just want the best value for my money. Is the i3 better then the intel Pentium or this laptop good?

Project Euler #7 (Not Posting Solution)

Learn Programming - Thu, 09/20/2018 - 20:48

Hello people, I've been trying to figure out the #7 project euler problem, I know that it's not allowed to post solutions outside because it kind of ruins the fun of it for some people.

I've been trying to figure it out for 3 days, on and off, between classes just sitting down and figuring out how to make it work and I came to the conclusion that I'm just missing a method or a concept to make it work (I'm a beginner at java)

Here is the code (pastebin) - I've written some comments - and uh, it's quite clear where I struggle.

If this is against the rules please tell me, I've read them and as far as I know, It's not.
