is there a reason  not to use a PS with a 12cm fan in a rack?
or can both 9 cm and 12 cm fan types been used  in racks?

Does anyone know of a company that would build a custom computer and ship it.

DELL & HP can't customize to the needs.

it's a very specific computer.
I have a new UPS 950VA BX950U-GR, just unboxed and plugged to line.
It's correct that no lights are on? If I turn on the ups I see green light flashing

My son has set up a Raspberry Pi in the home to display images. He enabled FTP and told me to connect via WinSCP. I have done this, and I see all the folders on the Raspberry Pi. However, I cannot upload images or do anymodifications on the raspberry pi due to a permissions problem.

Any ideas what could be the cause of this?

I am logging in with his username and password, which has full rights to the Pi.

Thank you.
I have HP z800 , 32Gb RAM, nvidia Quadro K2000, 2TB hd. In bios its showing every this is working but when ever i'm trying too boot a new window it restarts and crashes with that blue screen just before " Preparing Desktop  for 1st time ". I have no idea why this is happening.. I tried everything. check all slots, reinstalled every thing. but still same problem.
This whole thing was a sudden occurrence and not gradual. It started immediately after I pulled a stick of ram from my PC to install on another desktop I was working on. As soon as I replaced the ram that I removed back to my PC the problem started. I first thought that it was ram so I switched all the ram completely and the problem remained even with different ram. I then put my original ram back in and ran memtest and it found no errors and the problem still existed.  I have gone into task manager and slowly ended different processes to see if anything running in the background might be the culprit but that showed nothing. I've run malware and antivirus scans and eliminated all junk files,
I'm running Win 7 on a custom computer I built a few years ago with an 8 core AMD processor, an Asus M5A97 mother board and a 256 GB SSD with a couple of internal storage drives. (I don't overclock and I have made sure that the BIOS settings were set at "default".)
Does anyone have any ideas how to isolate the problem?
Any help would be appreciated. Thanks
Hi all

The UI for my react app has a main section (takes up most of the screen) and a left hand side pane.
I'm using 3 separate ag-grids:
-One as the main one on the main screen holding the important data.
-the other two are in the left hand side pane (the less important grids for assistance/statistic holding).

This left pane uses (two) tabs, i.e. click on one tab to see one ag-grid, click the other tab to see the other ag-grid

For the tab functionality, i used npm to install the NPM react-bootstrap-tabs node module.

Recently I managed to set up one of the left pain ag-grids to hold filtering information from the main grid.
This was quite a hassle since the grids were effectively grand-sibling components which needed to communicate. without touching AG-grid src code, I had to set up ag-grid callbacks to take note of the filtering data from the main ag-grid, send it up to the grandparent component of my app, and then send it back down to the other grand child ag-grid component.

It all works however I noticed a glitch. When initially loading the whole page, the first tab in the left pane is active by default. The left pane ag-grid that holds the filter information is in the second tab. What I want is to click on this second tab, and see filter data be populated automatically as i filter the main ag-grid. However when I have the second tab active and i filter the main ag-grid (i.e. adding filter …

Does anyone know where I can get a PCIe version of this PCI card?
Note: The USB ports on the above card are totally irrelevant.

I need to connect a new PC to a old KVM setup that uses PS/2 for the mouse and keyboard.
(The PC has one of those combo Purple+Green PS2 connectors which I can only get to work on a keyboard)

If such a PCIe card does not exist, have you any other suggestions?
Does anyone know how to have Windows Search look in SharePoint as a location? I have went into gpedit, Computer Config - Admin Temps - Windows Components - Search and Enabled "Add primary intranet search location". I added the SharePoint site to there, ran gpupdate /force, rebooted and still nothing.

Any ideas? Thanks
I am looking for testing strategy for Systems Integration Testing, speficially looking at documenting successful criteria.
ie components are all connecting, data tests \

Can anyone point me to a good article on this.

Hello all,
    What is a good UPS (battery backup) that has at least 5 outlets and network email notification? Does not have to be huge, just for 5 pieces of network equipment in a rack in our factory. Something like 1500va, but it needs to be able to email out, as there is no PC in that rack. If anyone can recommend anything, I would appreciate it.

I've built a flight simulator.  Now I want to put lights in it, plus console LED's, plus a bidirectional motor to extend/retract controls.  I'm a programmer by nature, and just starting in Arduino/electronics.  I'd like all of those components to be controlled via the PC via USB.  So, a few questions:

1. This is a lot of components drawing a lot of power, I have sufficient pins on an Arduino to control them all, but for power concerns do I need to make 3 separate devices (Lighting, Console LED's, and Motor) or can I run them all from a single Aruduino connected to the PC via USB (and AC power supply, if needed).

2. I know about the individual aspects needed for those, as in, I can light LED's, and I know I need an h-bridge for the motor to work in both directions, but can those be done on the same board? If so, can someone give me some sketches or designs on how to do it?

The Lighting LED's are RadioShack 39.3" (1m) Tricolor LED Strip for Arduino 2760339.  The console LED's would be somewhere between 5 and 10 multicolor single LED's I need to color from green, to yellow, to red.  The motor (and I could use some advice on this) needs to spin a threaded rod that will push/pull the drawer the controls are mounted on.  

If someone can either provide me with good drawings/sketches, or point me in the right direction, I'd appreciate it.  I'm an expert programmer, but just learning electronics, maybe halfway through the tutorials.
Hi, trying to access this drive:  model: RZ26L,   part number:  RZ26L-E  

Need to find cheap cable or adapter that will allow me to plug into this drive and extract data.
