I'm trying to figure out the best lower-budget home office development hardware setup. My laptop is aging.
My latest idea is that I would like a very powerful desktop paired with a less-powerful laptop. The idea being that the desktop would do the heavy lifting while the laptop would allow me to work untethered (but within range of the wireless network, of course.)
Is such a thing possible, or am I dreaming?
(I develop .Net applications - mostly Asp.Net)
Thanks for ideas!
You can do that with an RDP / Terminal Services client or VNC. You could also run multiple virtual machines on the beefy server (making it look like a poor man's datacentre / set of less powerful servers).
Another benefit is that you can do some testing with the laptop as the browser client and the desktop as server - this can sometimes show up issues that you won't see with testing on localhost (especially if your network goes down in the middle of it).
Yep, this makes sense and this will work. It's a similar model (but not the same) that's been used for unix workstations in the past (X window).
I would keep your aging laptop to use for testing thin client apps - who cares if it's aging how much power does it need to run Internet Explorer?
My dream development system at this moment in time would look something like this:
A couple of nice fast dual core processors
4 Gigs of memory
A couple of Intel X25-M 180Gb Solid State Hard Disks to run my apps off.
3 x 19+" high contrast ratio monitors, these 3 I have on my desk are wicked.
Ergonomic keyboard, I currently have the Ergonomic Keyboard 4000 which I quite like
Wireless Laser Mouse, I currently use the Logitech MX Revolution and I love it
A 2Tb SATA drive for extra storage space (just in case)
Of course, I don't have any of this at home, I have an aging laptop just like you. I have part of this setup on my desk at work and I keep drooling over the other bits and pieces.
You can use the desktop as some kind of a server and let both your desktop and your laptop compile.
It's like they render 3D CGI movies in studios, across a farm of computers.
This is exactly how my current setup is, and it works nicely. I'd still get a couple of 20"+ monitors, as the laptop can be a little restricting for long usage.

Ok so, my monitor is going black on random occasions. Mostly it is when i watch a video. It doesn't matter if it is on youtube, facebook, udemy or whatever other site.
I checked my cables they are all good. I also turned off the screen saver.
Any ideas what it could be?
there could be many reasons for this - bad drivers, bad cables, bad screen, GPU overheating and melting solder connections (I've experienced this).
the easiest thing to check is to see if the issue is in the computer itself. to do that, connect to a different monitor (using a different cable).
to check if it's a software issue, you could try running a LiveCD of a different OS on your computer (for example, Fedora or Ubuntu).
if the issue still happens even with a different OS, then it's likely a GPU problem - you'll need to either get that replaced, replace the mainboard (if GPU is integrated), or replace the computer...

Whanted to get a openvms dev enviroment, where could use it to learn the basic command's to get feel for it without worrying about breaking anything.
So whanted to know if its possible to install a openvms iso image in Virtual Box
In case its possible where could get a openvms image or needed first to get installation cds and from those generate the iso?
if the cds are needed is there some online store that can be bought or the price is only afordable for companies?
only making inqueries to see if its possible and feasible, other wise gona give up the ideia of having a development enviroment.
Well what do you know so far, and what do you have so far?
Do you know that OpenVMS has a 40+ year history, was originally written for the (32 bit) VAX platform, ported to 64-bit Alpha (30+ years ago), then ported to Itanium and X86 (64 bit).
That X86 port will boot natively and you may want to ue VMware, Virtualbox or similar - within the current constraints and offeringg - visit vmssoftware.com for details.
For initial learning I recommend to just to use an Alpha or VAX emulator.
Those could run on a virtual machine, but there is no good reason.
Just run as process on whatever laptop/server your have running Windows (and some Linux options I think).
There are are several emulators out there, both free and commercial - google is your friend.
I happen to like/use FreeAXP for Alpha running under 64 bit windows - just Google.
There is no Itanium emulator.
Do you have access to the software distribution somehow?
For starters, why even bother trying to get your own system?
Just timeshare to get a feel for it.
For example SSH to decuserve.org [184.168.131.241 - ooops: 104.207.199.162 ] - ask for an account - presto!
Other timeshare options are available - and very valid to learn the basics (file system, editors, compilers,...)
Good luck!
Hein.

There is WNS for Windows 8, Urban AirShip for Android and iOS devices but I can't seem to find an API for push notifications on Windows XP, Vista, or Windows 7.
Is there an API for these OS's?
If not, why isn't there? Is there a reason or is it just that no one want to invest in "hacky" technology for "old" operating systems?
I've never seen any natively supported push APIs for these operating systems, no. As Robert Harvey said there in a comment, the benefit likely simply does not outweigh the cost. People using those operating systems probably aren't overly invested in the next wave of technology, so nobody bothers putting in push notifications, which weren't really relevant on most desktop machines until Windows 8 was already released anyway. As for why they won't retroactively add it as an update, that's easy: money. If people want the new and exciting technologies of tomorrow, with push notifications and all, they have to buy Windows 8. Microsoft gains nothing by adding features like that into old operating systems.
But since I imagine you're asking this for a reason, I'm sure you could write a Windows Service with--ha--"relative ease" that would accept notifications (even, if you're feeling techy, through SignalR) and relay them out through the notification bar on those operating systems.
That could actually be a pretty cool piece of open source software to put out there: something that lets you set up push channels easily on those operating systems that will almost definitely never receive support from Microsoft for such behaviors.

has anyone having problem with latest release of arcgis 10?
my services running on ags 10 is very slower than 9.3.1.
And Arcgis Desktop is Really slow which cause me to downgrade back to 9.3.1.
Is it just me or anyone else having issues like this?
This "upgrade" from 9.3.1 to 10 is not worth it. I have a very new machine with fast processors and video cards and 10 runs much much slower. Just creating a simple buffer takes around 2 minutes where in 9.3.1 it would finish in about 10seconds. Unacceptable...
We just switched over to Arc 10 a couple of days before service pack 1 came out. We had some serious issues including speed problems with ArcGIS Server, Image Server and IMS. We applied the service pack and it took care of most of our issues on the servers.
We have not applied SP1 to the desktops or ArcSDE since we are limited by 3rd party tools that need to be tested first. But I am hoping that the problems we still see on the desktops hitting SDE will be resolved once we can apply SP1 there as well.
I have had arc 10 since September. Its been the worst experience of my professional career. Besides the crashes or lock ups 3 to 4 times per day, sometimes much more, it is the slowest program I have ever had the displeasure of dealing with. I have a brand new machine with up to date video card and 16 GB of memory and it still takes longer to do the simplest tasks that I don't see how they can stay in business if this is the norm. HORRIBLE HORRIBLE Exp. I would not recommend this to anyone. If there is another option besides arc I would definitely go with that.
I haven't had any problems with Arcgis 10. However please note that the system requirements for ArcGIS 10 are much higher than ArcGIS 9.3.1
What are your hardware & software specifications? Do they meet the minimum requirements?

I need to read the user's fingerprint from my application.
What I really want is a simple SDK that works with a lot of inexpensive fingerprint readers but I can deal with something that works only with one specific model if that model is cheap and available worldwide.
And it has to be royalty-free, I can pay for a development license but if I have to pay for each installation I just can't use it.
What I'm doing has no relation to login or encryption, so the software included with the reader will probably be useless to me.
There is no standard API for reading fingerprint data as far as I'm aware since it is a fairly new field and there's no standard way of doing it. Each manufacturer will provide their own API for reading the hardware. The API could just be IO specification to the hardware and there's no library whatsoever, which makes things a bit trickier. This is down to two factors. The first is that finger print readers are used in many applications - custom hardware, embedded systems through to PC authentication and beyond. Providing software for all those different systems would not be viable from the manufacturers point of view. Secondly, each manufacturer uses a different approach to reading and processing the captured images which would make a common API problematic.
It's an old question, but I bumped into it while researching the topic.
I did find a free library for Linux - libfprint
Digitalpersona has a free SDKs both for windows and linux.
http://www.digitalpersona.com/products/developer.php
I dont know if there are costs for deploying with their SDKs.
(Actually it appears they don't charge per machine/user licensing.)
Did you take a look at the BioAPI consortium site? There's a library for linux over at Google code.
There's also libchipcard, but it doesn't mention fingerprint readers, only smart cards.
Hope that helps.
Symbol has an api for their MC75 handheld devices:

Of course, it only works for their Windows Mobile 6 MC75 devices.
