Best products from r/computing

If all you are going to do is surf the internet and watch youtube videos, there are some really cheap netbooks (~$250). If you've never had a netbook before, head over to Best Buy or Fry's or someplace where you can try typing on them. It takes a bit to get used to the chicklet keyboards. If you want a full keyboard, you might want to get a 12" netbook or laptop. Also, decide if you like the glossy or matte screens.

Recently, I did a lot of research and decided to get an EeePC. The latest one is the 1015PN which is a 10.1" netbook that has the Nvidia Ion which allows it to play HD videos. The Ion also comes in handy when you want to play a few not-too graphics intensive games. There are drawbacks to this system in that it costs ~$415 dollars and only comes with Windows Starter 7 and 1 gb of ram. There is also a 12" version, the 1215pn with the same drawbacks. The battery life on these are pretty decent. If HD playback is important to you, I'd suggest either of these netbooks.

For myself, with a set budget of $400 dollars, I decided to go with the Asus EeePc 1015PEM. This has an awesome battery life (~8-9 hours of active use). With the money left over in the budget, I bought an extra gig of ram. I had a copy of Windows 7 Home from a previous laptop and did a fresh install. Now it's snappy and fully fun to use.

If you want a 12" screen, Lenovo also has a pretty decent 12" laptop I think. Although, I think it's a bit more than $400. They also have their own versions of a netbook. I think the popular one is the x200s. I might be mistaken.

Well it does depend on what you're working with as far as your power supply goes and how many connectors you've got for your card, since it's recycled you might not have enough for most cards out today. The good thing is though is that Portal 2 doesn't require a lot of graphical power to play.

Something like a GTX 730 or a R7 240 will be good and play Portal 2 really well.

You can also spend a little more and buy something like a used 5870 on eBay (if you're willing to buy used) for around £75 and will be a more "future proof" card for the system. The only issue would be making sure it's compatible with the power supply.

I have this acer. I bought it cause somebody here on reddit recommended it. The AMD fusion chip is great and can handle gaming pretty well. I used to play wow, terraria, minecraft, and even l4d2 on this little wonder.
Buy a 2 or 4 gb ram cause it only comes with 1 GB, and the difference once you upgrade is huge.

techexams.net has a pretty good community with a lot of great resources. I would start by going through their free stuff.

With that said, the Mike Meyers Network Plus guide is awesome. My wife used this guide as her sole study source and passed with a 884/900 with zero previous networking experience.

Yes as you said below, you really don't want a "mesh" network. That means something totally different.

You just want PoE access points that can do hand-of, which UniFI can do for sure. I use UniFI at my house and it's 100% worth it. Either of these will work:

https://www.amazon.com/Ubiquiti-Compact-802-11ac-Enterprise-UAP-NanoHD-US/dp/B07DWW3P6K/

https://www.amazon.com/Ubiquiti-Networks-UAP-AC-PRO-Access-Included/dp/B079DSW6XX/

but the first one (the NanoHD) is newer and supports 802.11ac wave2.

With unifi you really should go all-in with unifi equipment. That's when the system works best. I'd recommend this PoE switch:

https://www.amazon.com/Ubiquiti-Networks-Managed-Gigabit-US-8-150W/dp/B01DKXT4CI/

You get 8 ports of PoE ethernet and two SFP ports. You can turn the SFP ports into two more RJ45 gigabit ethernet ports (without PoE) with these:

https://www.amazon.com/gp/product/B01JUBXDPI/

Alternatively, if you need many more ports or want something rack-moutable, I'd use this switch:

https://www.amazon.com/Ubiquiti-Networks-US-16-150W-UniFi-Switch/dp/B01E46ATQ0/

You'll also need a computer that's always on somewhere in your house to run the UniFI controller software. The controller is how you configure and track everything. It's really light-weight, so it can just run in the background on a desktop or some old Mac or PC.

Alternatively you can just plug a "UniFI Cloud Key" controller into one of your PoE ports:

https://www.amazon.com/Ubiquiti-Secure-Controller-stand-Alone-Hardware/dp/B07BB4RGQD/

One caveat, if you use the cloud key make sure you back up your unifi database (on the controller) often. I've had them fail on me more than I like.

Finally, if you don't like any of those you can use a hosted instance of the cloud controller but it's $199 a year:

Unfortunately, what you're suggesting (DC storage to AC intermediate "wall socket" power to DC use by the device) is a bit impractical and inefficient. Many power inverters (a device for turning DC current into AC), can have efficiencies down to 50% when you use them in a trickle mode to "top off" a battery and near 90% when you use the full rated capacity of the inverter. As well, most digital electronics use DC power internally, this AC power you just generated will have to be converted back into DC power. This process will also loss some of the energy as heat as well.

Taken together, this means that you will probably need about two to three times the amount of battery (with associated weight) to run your "universal charger".

What I would suggest would be to have a DC power source you can tie directly into your portable device without having to convert between AC and DC twice.

First: Many small portable devices will charge off of USB. USB is already DC and they make dozens of battery packs (some rechargeable) that will supply power to anything that can draw current from a USB cable. http://www.google.com/search?q=usb+battery+pack

Secondly, if you need to supply power to a portable device which cannot charge off of USB (such as a laptop), your best solution would be to buy a specific external battery/spare battery for your laptop, that you can recharge from or swap to. Most modern OSes can save their current state to the harddrive (e.g.: hibernation mode), so you can power down, swap batteries and power up in seconds.

Edit: Would something like this be what you're looking for: http://www.amazon.com/Energizer-XP18000-Universal-External-Netbooks/dp/B002K8M9HC

Sipser's Introduction to the Theory of Computation is the standard textbook. The book is fairly small and quite well written, though it can be pretty dense at times. (Sipser is Dean of Science at MIT.)

You may need an introduction to discrete math before you get started. In my udergrad, I used Rosen's Discrete Mathematics and Its Applications. That book is very comprehensive, but that also means it's quite big.

Rosen is a great reference, while Sipser is more focused.

Keep in mind that card doesn’t have pass through so you won’t be able to view the game you are playing in your tv anymore so it will have to be through the laptop which can have latency. I would look at something like the Elgato HD60s here https://www.amazon.co.uk/dp/B01DRWCOGA/ref=cm_sw_r_cp_awdb_t1_SrhACbDEV3K9B
It costs more but pass through is a must.

As for a recommended laptop, you will definitely want a quad core or greater cpu and a graphics card. The recommended specs are on the page.

I just bought the $1,150 version (http://www.amazon.com/Samsung-NP700Z5A-S04US-15-6-Inch-Laptop-Silver/dp/B005KSQSGW/ref=cm_cr_pr_product_top) from the Microsoft Store.

They are running a promotion currently which is 25% off anything over $1,000. Great deal which brings this laptop down to $861.75 before tax. I went ahead and bought the 2 year accidental protection (it also came with a free copy of Microsoft office) for $150.

I'd return that watered down Best Buy version and try and get in on that Microsoft store deal if you can.

Well, I meant streaming from my computer via media server, to a PS3. I have a 2tb in my computer currently that my PS3 reads just fine, and it's formatted in NTFS. If it can read that via media server, I suppose it should do exFAT just fine too! if not, I suppose I could invest in something like this. I'm sure my wife wouldn't mind the nexflix/hulu/spotify hub right there at our TV/stereo. hm. exFAT it is! thanks reddit!

/r/techsupport would probably be a better sub-reddit for this. But, I'm not a sub-reddit nazi. We'd need a lot more info to help you though:

• Are you building this PC or buying to pre-built?
  
  
• If you are building your own PC what MoBo? If you are buying from an OEM, what make/model?
  
  
• Are you buying an all in one hybrid drive like these? or does your motherboard support using a msata SSD for caching? Something else?
  
  That'll get us started.

You do not need the exact same cooler. CPUs are built for specific "sockets". The one you linked is a 1150 socket cooler. So you can use this one: https://www.amazon.com/Intel-Cooler-LGA1150-1155-E97378-001/dp/B00BQ1C4SS

The cooler that I linked does not have pre-applied thermal paste(some do). So you would need to clean away the old paste and apply new paste such as: https://www.amazon.com/Arctic-Silver-AS5-3-5G-Thermal-Paste/dp/B0087X728K/

Their are quite a few video guides on how to replace the cooler for your computer if want to make sure your are not applying to little or to much paste. Im not sure i would be able to link any in your native language though.
