For those new to message boards please try to follow a few simple rules when posting your question.
Choose the correct forum for your message. Posting a VB.NET question in the C++ forum will end in tears.
Be specific! Don't ask "can someone send me the code to create an application that does 'X'. Pinpoint exactly what it is you need help with.
Keep the subject line brief, but descriptive. eg "File Serialization problem"
Keep the question as brief as possible. If you have to include code, include the smallest snippet of code you can.
Be careful when including code that you haven't made a typo. Typing mistakes can become the focal point instead of the actual question you asked.
Do not remove or empty a message if others have replied. Keep the thread intact and available for others to search and read. If your problem was answered then edit your message and add "[Solved]" to the subject line of the original post, and cast an approval vote to the one or several answers that really helped you.
If you are posting source code with your question, place it inside <pre></pre> tags. We advise you also check the "Encode "<" (and other HTML) characters when pasting" checkbox before pasting anything inside the PRE block, and make sure "Use HTML in this post" check box is checked.
Be courteous and DON'T SHOUT. Everyone here helps because they enjoy helping others, not because it's their job.
Please do not post links to your question into an unrelated forum such as the lounge. It will be deleted. Likewise, do not post the same question in more than one forum.
Do not be abusive, offensive, inappropriate or harass anyone on the boards. Doing so will get you kicked off and banned. Play nice.
If you have a school or university assignment, assume that your teacher or lecturer is also reading these forums.
No advertising or soliciting.
We reserve the right to move your posts to a more appropriate forum or to delete anything deemed inappropriate or illegal.
I hope this is the correct forum for such questions..
Is an adapter (the wrapper, that is) really needed in order to put a nano SIM into a micro SIM slot? I tried without one and there doesn't seem any problems. So, my question is, if I continue like this, apart from trivial "non-detection of the SIM card case", what is the worst that could happen? Agreed, those adapters are so cheap to buy, but just wondering...
Just a small hint: You might want to watch out for idle cooler noise if you plan to use it in your office. I once bought one where the description said nothing about it and even in idle it was many times louder than my PC

First of all always look for well known suppliers, that will give you better guarantee.
Then look for a true sinusoidal UPS, which means that the output is sinus shaped resembling the line waveform. The cheaper square-wave devices can create problems to switching power supplies of PC and other electronic devices. For more or less the same reason check the minimum allowed load power factor, this parameters directly deals with current phasing of inductive loads, but for electronic devices lower power factors means that the UPS can tolerate higher waveform distortion and the harmonics generated, again, by switching power supplies of electronic devices.
If you are looking for medium-high power UPS's looking at characteristics you'll find also an harmonic THD distortion, the lower the best.
About surge protection don't worry too much, an UPS device by default give surge protection: A surge is a fast transient overvoltage of power line (up to 200-250% of nominal value), because an UPS output is controlled and regulated you should be theoretically free from them.
Another important characteristic is the autonomy: how many minutes of power it can deliver at nominal power. This defines the dimensions of the battery pack. Choose the right time you need, the batteries are very expensive and are also delicate. Remember that batteries have a lifespan (that depends very much on ambient temperature, higher the temperature shorter the life), good quality batteries will guarantee a life of 18-24 months at 25°C +/-2°C.
I have always used VMWare on my laptop for studying purposes. The laptop runs an i5, 6GB RAM and standard HDD. It has performed pretty well overall for running 1-2 servers and a client over the last few years, but as you can imagine, it's at its limits!
I have picked out a new machine running an i7-4790, 32GB RAM, 256GB SSD with a 2TB HDD. It will be running Windows 8.1 Pro and as far as I can tell, the OS and spec support all the requirements to run Hyper-V.
I am aware there are only 8 threads on the i7, but this machine is only for study purposes so the machines won't be running anything too heavy and only running perhaps 3-4 VM's at once. How will the machine stack up? I know it will be a massive improvement in comparison to what I have now, but I don't want to spend out and then find there is a bottleneck holding me back!
PC power supplies require a minimal load to source output voltages inside the specification range. Some will check if a load is connected and switch off outputs with no load. So each of the 3.3, 5, and 12 V rails should be connected to some kind of load.
For the 5 and 12 V rails I would use an old drive (floppy, CD/DVD, or hard disk). The 3.3 V rail can be connected to a load resistor (e.g. 3.3 Ohm, 5 Watt). Finally you must connect the Power On signal (Pin 16/14 for ATX-24/-20) to GND.
It might be necessary to connect an additional load resistor to the 12 V rail because the load may be not enough when the motor of a conncted drive is not running.
Additional information can be found at the Wikipedia[^] page (see also the links at the bottom).
I've always just used an ink-jet all-in-one and called it good. I used to buy HP, but the materials seem flimsy now, so my current device is from Brother. There are some things that just aren't worth spending a lot of time thinking about. Go to a store that has a bunch on display and choose one.
Unless you foresee a change in line technology, I'd go for a combination. One less box to worry about. I have had a couple of ADSL modem + 4 port router + wifi boxes, and they do just fine. 3 wired ports in use and about 6 wireless devices. Whatever you get, make sure you lock down the admin access.

Go for the two in one option if oyu have a choice.
I don't have a choice as my ISP provides me with a fibre router(fibre cable in and one cat5 out) - I run a router/gateway off that.
My main computers then run off the gateway via Cat5 and I also have the wireless, on the gateway, switched on so that I can use mobile devices around the flat.
“That which can be asserted without evidence, can be dismissed without evidence.”
I look at the specs on various motherboards, and don't see anything about the number of monitors they will support.
A low-end motherboard will usually have onboard video capable of supporting one monitor. However, higher level motherboards will not have onboard video. For them, you must purchase and install one or more graphics cards.
The difficult we do right away...
...the impossible takes slightly longer.
Motherboards normally only support 1 or 2 monitors, one on VGA and the other on some digital. If you're going to run 3 monitors, seriously, forget on-board video. It usually sucks ass. You're going to get a separate video card.
You start with which CPU you're going to run, then you go to the motherboard and RAM. Which one you get depends on what you're going to do with the thing and whether or not you're going to tweak the chipset to eek out every bit of speed you can get.
On my rig, I have an Asus P8-P67 motherboad and run dual GTX770's, and (3) 24" monitors.
