Thoughts on Acer Aspire 7 (i5 Version) For Unity Development

Wondering if anybody could help me out, looking to pick up a decent laptop for college, I will need it to run Unity and occasionally Photoshop. I have a desktop with specs I'm happy with so I just need a laptop for working on while away from my desktop.

Considering this:

Any thoughts/advice/insight would be much appreciated!

MSI GS65 vs Zephyrus S

So, I'm gonna be travelling soon for a couple months and bringing my desktop isn't an option. I'm looking to buy a gaming laptop and I have it down between the Zephyrus S and GS65. I don't know which one to get. Right now ASUS is cheaper but I really don't know how I'm gonna feel about that keyboard. Any advice would be greatly appreciated.

Budget Smaller Notebook for Basic Document Works

Hello all, I am going to work outside office soon and I am planning to get a laptop to do some light document works on WORD. I am planning to spend less than 300USD as this will only be my at-work-typing-laptop, and a screen possibly below 12 inch since I will have to take it everywhere, size and weight is a concern. Also, Since I would be outside office, there is a small chance I can charge it mid-day meaning I will need a least 8 hours battery life.

I have been looking at Lenovo Ideapad S130, and Samsung Chromebook 3.

To sum up, what I need is (1) Less than 300USD; (2) Smaller than 12 inch screen; (3) Over 7 hours battery Life.

Please advise which is better or give suggestions on other possible devices. Thank you in advance.

Magnets and Printed Parts Make Quick-Disconnect Terminals

Hack a Day - Thu, 11/15/2018 - 22:00

The Apple MagSafe power connector is long gone from their product line, but that doesn’t mean that magnetic connectors aren’t without their charms. It just takes the right application, and finding one might be easier with these homebrew magnetic connectors.

We’ll admit that the application that [Wesley Lee] found for his magnetic connectors is perhaps a little odd. He’s building something called Linobyte, a hybrid art and electronics project that pays homage to computing history with very high-style, interactive core memory modules. The connectors are for the sense wire that is weaved through the eight toroids on each module, to program it with a single byte. Each connector has a 3D-printed boot that holds a small, gold-plated neodymium magnet with the sense wire soldered to it. A socket holds another magnet to the underside of a PCB. The magnet in the boot sticks to the PCB and makes contact with pads, completing the circuit. We know what you’re thinking: heating a magnet past the Curie point is a great way to ruin it. [Wesley] admits that happens, but it just makes the connection a little weaker, which works for his application. The short video below shows how he puts them together.

We can think of a couple of ways these connectors would be useful, and we really like the look of the whole project. It’ll be interesting to see where it goes, but in the meantime, brushing up on how magnets work could be fun.

Getting a segfault from what I assume is the command line arguments

Learn Programming - Thu, 11/15/2018 - 21:52

Hello all, I am currently trying to run this; https://pastebin.com/2vGEYt6s But keep getting segfaults. I am almost positive it is because of my command line arguments. My input is supposed to be something like;
./a.out 75 4 1 5 10 25
then the first two variables are read in, then the following are read into an array. It is solving the coin change problem here;

How to replace <a href=""> value when switching to specifict media query.

Learn Programming - Thu, 11/15/2018 - 21:52

I have a media query for when my site goes mobile. I would like for the a href to go to the specific div id on the page when on mobile. But when on landscape/on desktop mode, I want it to go to the top of the page/remain there rather than it taking me to the specific div id.

IOW:

Go from this when screen width >= 450px:

<div> <a href="#myLink">Click Here</a> </div> <div id="myLink"> <p>Lorem50</p> </div>

To this when screen width <450px:

<div> <a href="#">Click Here</a> </div> <div id="myLink"> <p>Lorem50</p> </div>

Note: I don't much JS and am learning. I'm pretty sure it involves it.

Hi guys! I'm really new to programming. I'm trying to learn how to create a whole data base with an interface but I would like to know what source material you guys recommed. I like looking at step by step tutorials but there's a lot in youtube and I really find myself confused on what to choose.

Do you have a channel or web page you find useful to learn this from 0?

ps. I do know how to create tables and how to connect and oracle db to java.

Great 2-in-1 Laptop For Black Friday ($900 range)

* **Total budget and country of purchase:**

$900 (including potential Black Friday markdowns), U.S.A

* **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'm looking for a 2-in-1 laptop with great specs (a decent battery life is a plus!)

* **How important is weight and thinness to you?**

Semi-important, I'd rather my laptops be lighter than 4.5lbs for portability

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

Windows is preferred, but I can roll with other OS as well (except for Mac)

* **Do you have a preferred screen size? If indifferent, put N/A.**

Around 13" to 15" (no less)

* **Are you doing any CAD/video editing/photo editing/gaming? List which programs/games you desire to run.**

Light gaming & digital art. So nothing too crazy (like just Photoshop & SAI)

* **If you're gaming, do you have certain games you want to play? At what settings and FPS do you want?**

Not really, I'd like to have the ability to game just in case

* **Any specific requirements such as good keyboard, reliable build quality, touch-screen, finger-print reader, optical drive or good input devices (keyboard/touchpad)?**

Good touchscreen & pen are preferred. A reliable build quality is also needed (as my current laptop is plasticy and falling apart). A good keyboard is a plus, but not required.

* **Leave any finishing thoughts here that you may feel are necessary and beneficial to the discussion.**

I was debating on whether I should get the HP Spectre x360 13t or not, and I'd also like to know better laptops available in this price range!

Have you ever saw someone else's source code that improved your own coding practices?

Learn Programming - Thu, 11/15/2018 - 21:28

I know this is a very broad topic but I found that a lot of my current coding practices were from mimicking sample codes I've seen in other people's github repos. I was wondering if anyone has links to random repos that helped them develop their coding practices.

I think it would be helpful to have a discord or maybe even a slack for this subreddit. That way people can get answers to questions faster and there can be more general discussion.

Picking a new laptop for everything

Total budget and country of purchase:

Maximum $1500 or $1550 (although Black Friday is coming so I'm hoping for discounts)

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'd like a battery life > 5 hours, don't really care if it has touchscreen or a 2 in 1 feature (regular laptop is fine).

How important is weight and thinness to you?

Don't care about the weight but don't want anything too thick.

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

Anything but ChromeOS, currently using macOS but planning to switch to Windows

Do you have a preferred screen size? If indifferent, put N/A.

Anything between 13" to 15".

Are you doing any CAD/video editing/photo editing/gaming? List which programs/games you desire to run.

I'd like to run mostly software/web development tools (Jetbrains IDEs, text editors, not at the same time), and I would like it to run at least CS:GO.

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

If it can run CS:GO (above 30 FPS would be nice), it's good enough. Would be nice if it could run GTA V at lowest settings at above 30 FPS, but not required.

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, build quality, an SSD bigger than 128 GB (256 GB is fine), and a screen with a resolution higher than 1080p are important to me, I don't need a touchscreen or a fingerprint reader. I'd like it to look normal, the something premium feel of the Surfaces, XPS's, and MacBooks, and not like a gaming laptop.

Leave any finishing thoughts here that you may feel are necessary and beneficial to the discussion.

So far I have picked the Surface Book 2, 13", i5, 8 GB RAM, GTX 1050 for $2000 - I've been seeing a lot of discounts from a few companies, so if a laptop costs $2000 such as this one, I'm hoping I could find it somewhere on Black Friday with at least 25% discount for $1500. The Surface Book 2's seem reliable, not having many technical issues reported.

I was also thinking about the XPS 15 or 13 with 4k, but the XPS's apparently tend to have a lot of issues where it needs to be sent for repair - not as reliable as the Surface Book 2's.

I currently have a MacBook Pro retina mid-2014 with i5, 8 GB RAM, 128 GB, but the new MacBook Pros' keyboards tend to be unreliable and malfunction - also the typing experience isn't very good on the new ones.

I should also mention that I will be using this laptop all the time (as I have until this point), without having a powerful desktop.

Looking for a Laptop to Replace my Desktop

Hi there!

I'm looking for a laptop to replace my desktop: I've moved countries (US) and am living in a dorm and no longer have the space for a desktop and am also travelling a lot (every few months back home to NZ). I've looked around at the Clevo shells built by Origin Xotic etc. but they seem pretty bad for the price (then again I have no idea because I'm not well versed in laptops). I'll be using the computer mostly for heavy video editing (I shoot on a Blackmagic Cinema in its proprietary RAW and do some colour correcting, and a Canon 5D MKIV RAW) and gaming (not too fussed, mostly just play Dota and a few titles here and there. When I go back to NZ for holidays I'd be playing games all the time and won't be doing work on it). Here's what I'm looking for:

Budget: No real budget, so long as it's not ridiculous for what I'll be using it for. Would like not to spend over 5000 USD

Processor: I'd rather a desktop one than a mobile one, anything with power equal to or higher than a 7700k would be nice. The Xotic/ Clevo ones go up to 9900k and I'd be pretty happy with one of those too.

GPU: Preferably a 1080 or Quadro equivalent, I'm not sure if Quadros are worth the price especially in laptops though

Screen: Not too fussed as when I'm editing I should be connected to an external monitor, would like a 1080p screen 144hz as when I'm not using a monitor I'll

probably be playing Dota.

Storage: Again, not too fussed as most my stuff are on a disk array stored separately. A SSD to store my OS and a few select programs and games, nothing over 500GB, and a secondary HDD or SDD would be nice but not necessary.

Battery life: Don't care, doubt this configuration would have good battery life, plan to use it tethered 90% of the time anyway.

RAM: I'm under the impression from websites and IRL advice that I should go for 64Gb for my workload, but I'll take any into consideration any amount.

Size: Don't care at all :D

IO: Thunderbolt would be nice, the more connections the better. Not too fussed here.

Again, I'm very new to desktop replacements and have no idea what's a fair price. I tried to configure one on Xotic and Origin and there was a 700$ price difference even though parts seems similar... Any help would be appreciated!

Thanks so much <3

C Programming How would I create a matrix without asking for row and columns?

Learn Programming - Thu, 11/15/2018 - 21:14

Almost every matrix lesson Ive seen asks the user for the number of rows and columns. Is there a way to maybe create a matrix big enough just to hold a certain amount of numbers? Like if I had 10 numbers it would automatically create a 4x4 matrix.

Steps to improve and think during problem solving for programming programming

Learn Programming - Thu, 11/15/2018 - 21:11

I know it is essential to do lots of practice problems like on leetcode/hackerank. Also, projects will help a lot for problem solving but when you are doing those problems, what are the steps in order to solve a problem? I practiced a lot of coding questions but when it comes to questions that I haven't seen, my mind goes blank and can't think of ways to do it. Can you improve on problem solving and how? Thanks!
