An embedded system is a computer system with a dedicated function within a larger mechanical or electrical system, often with real-time computing constraints. Examples of properties typical of embedded computers when compared with general-purpose ones are low power consumption, small size, rugged operating ranges, and low per-unit cost. Modern embedded systems are often based on microcontrollers; the processor(s) used may be types ranging from general purpose to those specialised in certain class of computations, or even custom designed for the application at hand. A common standard class of dedicated processors is the digital signal processor (DSP).

Hello Experts,
How can I make sure my Dell T3610 has vPro technology?

Thank you,

I have a customer with a Dell PowerEdge 6800 whose experiencing back-to-back-to-back hard drive faults (either failure or predictive failure) in one particular SCSI slot - Slot3. RAID5 configuration.  
After the initial failure the drive was replaced - rebuild failed.
2nd drive replacement - predictive failure.  I then had the admin take the drive offline.
3rd drive replacement - rebuild failed.
All drives are refurbs and 1:0 - 1:3 are the same DP/N Y4707 - Seagate (ST3146854LC) drives.
The customer requests that we try DP/N FC958 - Fujitsu (MAX3147NC) drives, the same drives as in 1:4 - 1:11.
I'm thinking backplane or storage controller as the culprit.
Any thoughts?

Hello Experts,

I've heard different things about applying thermal paste and wanted to know what you think.  Some people say to use the pea/line method and some say to evenly apply a thin layer to entire CPU surface before installing the heat sink.

Not sure which one to go with; it seems that the full coating method will increase the total area of heat transfer and get better results, but wanted to hear your opinions on this.

I'm starting a project in which I will be using this panel pc (http://www.icop.com.tw/en/product/Panel-PC-PPC-090T/PPC-090T.html) to  show a basic interface screen and it will interact with a controller system using a serial port or usb.  

My experience is in developing windows desktop apps and most recently object oriented web development.  I've never worked on a platform like this (linux & native app) and I need some guidance.

First of all, which OS would be most suitable for a simple application like this.  Again the custom UI will be a nice looking dashboard style interface and will use a touch screen but the operator will never need OS access.  

Also, in terms of a development tools, if you were working on this project (in general) what would your dev toolset look like? For example, which  IDE would typically be used, programming language typically used for this kind of application, frameworks if any etc.

I'm using this panel pc for a custom application

The panel PC http://www.icop.com.tw/en/product/Panel-PC-PPC-090T/PPC-090T.html

I need to mount it vertically aka portrait mode.  It will be running a custom app constantly with no user access to the OS (ubuntu).  Do you think I'll be able to force the display to rotate so I can mount it vertically (portrait mode)?

I'm new to this and I'm not sure if it's a no brainer or impossible.

I recently had a custom computer built by a local computer store.  I told them the basics of what I wanted, which is to have a beefy PC that can handle music composition software (Cakewalk Sonar along with software synths, sampling software, and audio efx plugins), Video editing software (Sony Vegas 13 and special efx software/plugins), and finally 3D design software (3D Studio Max, Daz Studio, Vue,).  So I ended up with the following machine:

CPU: AMD FX-8320 3.50 GHz (8 Core Processor)
Motherboard: Gigabyte 990FXA-UD5
RAM: Corsair 16GB (2 x 8GB) DDR3 PC3-12800
GRAPHICS CARD: NVIDIA GeForce GTX 970 (4GB)
AUDIO: Focusrite Scarlet 2i2 (USB connection)
Rosewill Lightning-800W ATX Power Supply
Windows 8.1 64-bit
Two (2) Internal Hard drives, Seagate, C drive=500GB, D drive=1TB

They also installed a very large CPU fan/cooler (Not the one that was supplied by the CPU manufacturer, because they told me the stock fans are not recommended and don't do a great job of cooling the CPU).  I was okay with that except I discovered that the CPU fan blocks two of the four RAM Memory slots.  So I have two 8GB Modules in the first two slots, but in order to get DUAL CHANNEL RAM, the 2nd module would have to be placed in one of the blocked slots.

When I picked up the computer, the technician who built the computer did not make me aware of this.  It was only after I read the motherboard manual that I realized the module is in the wrong slot.

So my question is, even though

I am wondering if somebody who had built a few Arduino projects would be able to tell me whether it would be possible to do the following with Arduino - perhaps with two Arduinos. What I want is to have the following:

a virtual full Qwerty keyboard program in computer A

I type on this keyboard and the 'typing' is piped out of my computer via Ethernet preferably (though if this can only be done with another type of media/protocol I will be happy to go along)

at the other end of the Ethernet - (or other media) - the keystrokes I have typed in are accepted and processed as if they were of local origin

Example:

in the virtual keyboard on computer A I press F5
computer B responds just as if had press F5 on a local keyboard

(Note that I accept the possibility that F5 at the time I press it may mean nothing to the software running on computer B - the assumption is that it will mean something because I have software in computer 2 that will respond to F5 though it may not respond to F6. All that is a different issue - at this point I just want it to be that if F5 typed locally would have done something the redirected F5 from the remote computers virtual keyboard would accomplish the same end.)  

I understand that I may need 2 Arduinos for this - one at the sending end to prep the keystrokes for transmission via Ethernet/TCP IP and another at the other end to 'convert' to 'local keyboard input'.  

If in fact this has already been done/a prototype exists that …

My work Windows 8.1 Pro desktop PC is fairly basic.  It isn't the most powerful but I have plans to use it for years.  I am wondering if I can get a noticable boost in graphics performance with a graphics card.

Summary
I do NO gaming.  

I use Office programs, occasionally program in Access or MySQL, do research online a lot, stream videos, and a couple times a year edit movie clips with Movie Maker.  Not the most sophisticated graphics!

Here's the thing:  I built my PC with some new stuff:  motherboard, CPU, RAM.  I brought two SATA3 HDDs with me, as well as my wireless keyboard, mouse & 23" HD monitor.  I also installed an older PCIe 2.0 graphics card with 1 GB DDR2 RAM.

I looked at benchmarks for graphics at passmark.com and the integrated Intel HD 4400 was rated higher than the GeForce GT 220 card.

Details
Windows 8.1 Pro 64-bit
Intel Core i3-4150 CPU
Gigabyte GA-B85M-DS3H motherboard
(2) WD SATA3 HDDs, 1 TB each
Crucial Ballistix 2x4 GB PC3-10700 DDR3 RAM
Samsung Syncmaster 2233 1920x1080 monitor
Antec Earthwatts 500W PSU

Is there a decent graphics card for less than $100 to boost my performance?  Or would I be better off using the integrated graphics - and perhaps using less energy?

Note - at some point, I plan on installing an SSD at least big enough for Win8/10.  This has been a budget build, converting from a previous PC;  not going to break the bank on any components.

Hi,

I have a sugarcrm deployed in a Linux server.

I have a control Access hardware, and i want to know if it is possible to integrate it with sugarcrm. For instance i know asterisk VoIP can be integrated with SugarCRM but i don't know how.

I want the control Access instaled, and when ppl swipe the card sugar CRM knows who are entered, etc...

How can a hardware be integrated with the software? what special skills i need to do that? I think an API would be required, who can help me with that? a php programer?

I need some tips to do that, i don't know where to start.

Thx a lot

techs, I have constantly seen in the specs of Lenovo's laptop that it will take a max 8 gigs? Now my question is, if I have windows 7 and it has 2 slots, why cannot I add up to as much ram as will fit? Instead of 2 4 gig dims why not 2 8 gig dims or 2 whatever  to get past 8 gigs?

We have a SAMS POS system that just died.  We have decided we are going to switch to pcAmerica Cash Register Express but the demo is limited to 200 sales and it is the weekend currently as I write this so options are limited.

Any recommendations on what can be used in the interim?  We have our store inventory file with all UPC items, current pricing, and current inventory quantities to use.

Hello,

I want to purchase a network backup device. I have around 100 users in the network and need storage capacity of 16 TB with RAID mirror. My requirement is to have day & datewise backups from the user computers including the mail client as outlook express. Also require a software which can give the facility to configure which drive backup to be taken and which file type backups to be taken. Along with this also want to take the online backup of SQL database from the server.

Please advice few of the device which can give all such options and facility.

So, I'm trying to create a hello world old-school Windows CE program, but I don't have a device handy.  I downloaded Microsoft Embedded Visual C++, which I understand to be the Microsoft tool to create Windows CE programs, and which also seems to have an emulator (I want to develop on my desktop then move to the Win CE device).

So it installs fine, then I say File->New Project, WCE MFC Appwizard EXE.  I create the skeleton program, then try to build it.  The project type is "Win32 (WCE emulator) Debug" and "STANDARDSDK Emulator" seems to be the target.  It builds and then I get a progress dialog that says "Connecting to the device", "Starting Emulator Startup Server."  This progress dialog seems to take forever, then it goes away and in the Build dialog it says:

Test.exe - 0 error(s), 0 warning(s)
Downloading files
Timeout: Failed to connect to the device
Failed downloading

This is RIGHT out of the box, after MSEVC install, so I figure others must have run into this.  Is there something else I need to do to get the emulator running, and run a hello world program in it?

Thanks.

I have a dell workstation (Precision M6500) laptop that has been malfunctioned due to heat and now I wanna use its processor which is I7 but i'm not sure if it fits on desktop. I took the laptop parts and the processor looks like a desktop processor but i'm not sure if it fits or not.

how do I know for sure if it fits on desktop and what kind of motherboard would it support it? Is there anything I need to read on the processor?

I'd appreciate any thoughts

Is there a way to make a Raspberry Pi boot via PXE?  
Are there any similar devices that could boot PXE?

What are the complications as far as the image that would be downloaded by the PXE bootstrap?

Hi,
I recently purchase a new notebook Dell Latitude E7240. It comes with smart card reader slot and contactless smart card reader. I have no idea whether this built-in things really working or ready to work. I browse everywhere in my notebook, but there is no software installed except for the driver stated as follow:
Aladdin IFD/VR Handler
MS Usbccid Smartcard Reader WUDF
Rainbow ikey Enumerator
Rainbow ikey virtual reader


I am thinking of using it as authentication. Let say, I want to use it to authenticate a specific web page.
What software do I need ?

For a start, I would like to just read my smartcard and display whatever data stored inside it. Later once it done, then I can extend it to use the data as authentication to my webpage.

Ok, I'm stumped...

I recently purchased a Dell (Dell Inspiron 13 7000 Series i7347-50sLV 13-Inch Convertible Touchscreen Laptop (Intel Core i3 Processor, 4GB RAM) ).

As with most laptops, it shipped with Windows 8.1. I figured that with some diligent hunting, I could downgrade to Windows 7 Pro x64 and find the drivers online. After trying about 10 dead-ends drivers, I'm out of ideas.

The Hardware ID seems to suggest that it's an Intel Proset WLAN 7265 (at least that was the guess of a Dell tech support guy), but none of the drivers are working, even those slated for Windows 7.

I've attached a screen capture with the Hardware ID. Can someone help?

Thanks in advance.
