Submission + - Platform independent C++ OS Library?

Submitted by quench
quench writes: Hello! I have been away from Windows and Linux application software for 5 years or so, doingly mainly C-like embedded C++ programming.
Now, I am about to start a project emulating embedded hardware on Windows. Been there, doing #ifdef WIN32 and #ifdef LINUX stuff, don't really want to go there any more. What I actually need is a platform independent lib covering Windows and Linux variants to handle sockets, IPC and threads abstractions. And a rock solid but simple embedded database to emulate flash memory.
My reflex said, go for ACE (http://www.cs.wustl.edu/~schmidt/ACE-overview.html) and Berkley-DB (http://www.oracle.com/technology/products/berkeley-db/index.html).
Tell me, am I out of time? Am I missing something new and trendy, easier to use and better? Did time stand still?

Submission + - Mobile Wi-Fi Hot Spot

Submitted by bsharma
bsharma writes: What if you had a personal Wi-Fi bubble, a private hot spot, that followed you everywhere you go? Incredibly, there is such a thing. It's the Novatel MiFi 2200, available from Verizon starting in mid-May ($100 with two-year contract, after rebate). It's a little wisp of a thing, like a triple-thick credit card. It has one power button, one status light and a swappable battery that looks like the one in a cellphone. When you turn on your MiFi and wait 30 seconds, it provides a personal, portable, powerful, password-protected wireless hot spot. The MiFi gets its Internet signal the same way those cellular modems do — in this case, from Verizon's excellent 3G (high-speed) cellular data network. If you just want to do e-mail and the Web, you pay $40 a month for the service (250 megabytes of data transfer, 10 cents a megabyte above that). If you watch videos and shuttle a lot of big files, opt for the $60 plan (5 gigabytes). And if you don't travel incessantly, the best deal may be the one-day pass: $15 for 24 hours, only when you need it. In that case, the MiFi itself costs $270. In essence, the MiFi converts that cellular Internet signal into an umbrella of Wi-Fi coverage that up to five people can share. (The speed suffers if all five are doing heavy downloads at once, but that's a rarity.)... http://www.nytimes.com/2009/05/07/technology/personaltech/07pogue.html?_r=2&em

Submission + - Why Dell won't offer Linux on its PCs.

derrida writes: "Jack Schofield explains in his article why Dell won't offer Linux on its PCs. Quoting from there: "The most obvious is deciding which version of Linux to offer. There are more than 100 distros, and everybody seems to want a different one — or the same one with a different desktop, or whatever. It costs Dell a small fortune to offer an operating system (it involves thousands of driver compatibility, peripheral testing, certification, staff training, administration, advertising and support issues) so the lack of a standard is a real killer. The less obvious problem is the very high cost of Linux support, especially when selling cheap PCs to naïve users who don't RTFM (read the friendly manual) and wouldn't understand a Linux manual if they tried. And there's so much of it! Saying "Linux is just a kernel, so that's all we support" isn't going to work, but where in the great sprawling heap of GNU/Linux code do you draw the line?""
