may be better hardware threads support ? better support of the Atom chip sets ?
may be INTC wants it's own Android with 1000s existing clients ?
and may be INTC wants to get rid of WinCE ?
check http://gomyplace.com/ it is not fully implemented, but if you are interested i can bring the product to the production phase fairly quick and make it embeddable. integration with vxWorks is not a problem. Or just consider the idea.
hardware reboots - there are relays which can be controlled remotely, including HTTP interface. Again I could help you here - i can reverse engineer software for the existing hardware and put support you need, like SSL or SSH. Also you can consider developing of the hardware - this is not prohibitively expensive as many think. Such hardware can be sold as a separate and profitable product. The market of remotely controlled relays still is limited.
I got my first 6 figure check (annual) without any education at all. I just knew to write code and I probably did this better than many others and I was ready to work 80+ hours/week for the kind of money the company paid me. MIT sounds cool, but there are many other schools around where you can start to learn. And I suggest to look for a job constantly. I worked and studied in the same time ad I do it now for my BA degree.
I found my first job by visiting offices of startups (in the second office I was hired) and demonstrating an application which could plot 3D graphs of functions of two variables and contained a "calculator" which could do derivatives analytically, like you enter d(cos(x)-x)/dx=? and you get sin(x)-1. The most complex part was to remove from the result all (+0), (*1) and find all 2*x^2+3*x^2 and others like this and add them together. I am not sure that my future boss really appreciated the effort, but i got my first programming job. This was 10 years ago and now may be this is harder than then, but not impossible
...or on could use a dedicated search engine of resumes posted online like one in my i-am-still-going-to-do-but-i-do-not-have-time-pet-project http://www.cvfinder.org/
My really cool idea would allow to run a search engine on a single high end desktop and be able to parse and indexed 10s-100s of millions of CVs online.
but only after our loans are paid back with interest
... and this is where the problem starts. too many guys over there including the bank itself do not believe that loans the bank holds are going to be repaid. Check e-trade recent deals. According to some estimations ETrade got less than 0.25$ for every $1 of sold mortgage backed securities.
Every public phone has a box connected to 48V power line and is weatherproof. BT or ATT could provide unlimited VoIP service everywhere with close to 100% coverage. I can build a board with DSL and WiFi which can plag&play into a public phone. When I mentioned this idea to a couple of VC types they laughed. Am I stupid ? I found on the Net that there was at least one attempt to roll such network in NYC and London. Probably the attempt failed.
Just because our currency lost value against another country's doesn't mean we're now "poorer" than they are.
US actually imports vast majority of goods. Not only from Europe, of course. Mainly China. Latin America, Canada and Europe. Check also prices of gas - such things tend to make you poorer
yes, same here. You need that letters and faxes to send just to get an evaluation version for a period of month. Common - we are tired of this shit. I want to click and download the image and I do NOT want to send an e-mail and ask for the license key just to compile the image. and I do NOT want to look for the license file and I do NOT want my compiler to spend any CPU cycles for checking if my (floating) license is valid. And I DO want to be able to replace NIC in my server.... etc etc. This is ridiculous and annoying.
Guys, tell me that the installation is free and a simple download of TAR file and I will go to your WEB site. And, please, make the registration optional.
if the license language follows the one of WinCE (MS) I would not touch it.
WinCE will cost you $800 and You have to call a representative and prove that you are a major manufacturer or an university or something to get the source code.
If the licenses is not GPL or BSD or any other "free" open source license they did about nothing. Indeed ability to look into source code is interesting, but in reality the need arises rarely. I spent 10+ years in vxWorks world without access to any source code and applications I developed work just fine. The same with WinCE - I had an access to part of the code, but frankly I never looked there.
I can try to put a short list of reasons why You can ask for the OS source code
- you are a kernel developer porting the OS to new CPU or a board radically different from the existing and supported already
- you are a manufacturer who strips (or inflates) the OS to fit the marketing needs and discovers that kernel's API is not flexible enough for yet another 10 drivers.
- you need every microseconds of the CPU performance and literally count CPU cycles and you need patches in the scheduling scheme or TCP/IP or packet filter
- you work with relatively large and/or young and/or buggy and/or bad documented kernel and unstable (backward compatibility) kernel API (i love Linux btw, but the truth is... you know... )
The list above is not full, but probably covers some of the possible reasons. How QNX fits here ? I bet they provided source code to their large customers. These news is just another sign, that competition with Linux in embedded world heats up. IMHO QNX is may be 5 years late.
same here. A linux (Ubuntu) desktop for browsing and Windows laptop for watching TV, video streams. I explained to my mom that Internet is a dangerous place and that she should use Windows only for A, B, C (for example, access of the bank account, because bank WEB site does not with Firefox and for videos, because streams are DRMed). All required icons (in total under 5) are on the desktop.
Both machines are behind a router/NAT/firewall and both machines run their own firewalls. I am using no antivirus software.
Actually my mom is not even aware, that she works with to different products - Linux and Windows, and I suspect she does not know these two words either.
yes, if ISP really wants to block and is ready to invest money it can be done. the problem is false alarms. the system should be reliable. the backbone box will not be cheap. doable, of course, but increases costs per customer. bandwidth is cheaper (probably)
re: "you can easily get overwhelmed with misbehaving UDP clients endlessly sending layer-7 connection-request"
The same problem exists in the TCP network and called SYN flood attack. Usually downstream is wide enough to handle fairly large amount of connect requests unless this is a deliberate attack against a specific node.
There are many issues with UDP based protocols, but Gnutella proves that this is possible. I did a prototype (Rodi) by myself. Such network can work. UDP (or more precise packet based raw data) based protocol makes it easy to use ICMP/DNS or just any type of tunnel you can think of
DPI box is a "man in the middle" thing and sees the whole key exchange. I would say that even IPSec with dynamic keys is not secured enough. Static keys (you get a key on the flash disk by post, for example) are secured.
...according to Vyatta 1.5GHz CPU can fill 45% of 100Mbits/s link assuming packet size 64 bytes. It means that likely performance of this USB firewall is well under 20Mbits/s
the suggested scheme is problematic - will require queue of pending packets in the Windows driver and some additional tagging. It looks simpler just to run the packets via the dongle in and out.
Anyway I doubt they stand in 100 Mbits/s line rate when they decompress on the fly gziped streams and check the download by antivirus and run Layer 7 packet and above packet inspection (think about AJAX) and this is basically what they say in the product description.
Some enterprise boxes do similar tricks - full inspection of TCP/IP-to-HTML layers. Typically these are 3U boxes with lot of network processors and fair amount of proprietary logic.
400Mb/s theoretically speaking. I think that PXA270 has a 64 bytes incoming and outgoing buffers for USB, so they need interrupt every 2 micro to handle incoming packets. Bulk mode is low priority and just any device connected to the same hub will have higher priority or share that 400Mb/s.
Slashdot Mirror
Assembla.com and some others integrate everything (WEB cam, chat, wiki, git/svn, blokg) in one low cost WEB based application
wxWidgets emLib http://larytet.sourceforge.net/ are two options I used. emLib is available in LGPL - contact the author.
VLC (videoLAN) uses wxWidgest Multi-thread application which is fairly close to what embedded application looks like
Emlib is a thin wrapper. No sockets though. http://larytet.sourceforge.net/
One answer - go for Linux if you want to avoid single vendor point of failure. Go for commercial Linux like TimeSys if you insist to pay money.

it is pain, but i think it is possible. i tried 500 miles with only gas stops once. pain is all you feel, but it is possible.

traffic shaping is tough to fight with, but not impossible. DNS or ICMP tunneling can make the shaper work harder.
check this out http://larytet.sourceforge.net/howto.shtml
3 pages down look for "Ellacoya promise that the shaper is statefull is true..."
any UDP based protocol will solve the problem. For example ICMP tunnel or DNS tunnel are interesting options
