Raspberry Pi's Eben Upton: How We're Turning Everyone Into DIY Hackers

psergiu Re:Eben Upton? (90 comments)

Nope.
But Eben himself is a good actor - you might have seen some of his movies, his screen name is Jason Statham.

Born To RUN: Dartmouth Throwing BASIC a 50th B-Day Party

psergiu Re:BASIC bad, ?? good (146 comments)

I recommend MMBasic on a Maximite

Quoting from http://mmbasic.com/ :

MMBasic is a free and open BASIC interpreter for 32 bit microcontrollers.

It includes floating point numbers, extensive string handling, multi dimensional arrays and structured programming features like do loops, multiline if statements, user defined subroutines and functions.

MMBasic is generally backwards compatible with Microsoft's MBASIC and implements much of the ANSI Standard for Full BASIC (X3.113-1987).

Born To RUN: Dartmouth Throwing BASIC a 50th B-Day Party

psergiu Re:Mixed blessing (146 comments)

Well ...
BASIC is still used in the micro-controller & embedded device, and is now structured as ever.

Check out MM Basic

Born To RUN: Dartmouth Throwing BASIC a 50th B-Day Party

psergiu Re:Celebrate (146 comments)

Get your kids a Maximite.

80Mhz, 128Kb RAM, 8 colour, Stereo Amiga-MOD playing, very hackable BASIC computer.

Just add a VGA monitor, PS/2 keyboard and SD card for storage.

Raspberry Pi Compute Module Release

psergiu Re:How about a backplane? (51 comments)

It depends.

How about a 1U rack-mounted box, with redundant PSUs, hosting around a hundred of Pi SODIMMs, with a USB-Ethernet chip for each slot, every X (7..24) ethernet lines connected to a switch chip with a gigabit uplink on the back of the enclosure.

Current RPi USB-Ethernet is slow because of the USB-HUB-and-Ethernet chip used. You won't have a USB hub in this configuration, and you can use a better USB-ETH chip.

Also you don't need a single, huge, expensive PCB. You can have multiple small PCBs side by side each one hosting just X (see above) cards.

Put a small switch next to each RPi DIMM slot on the board so you can power them off and replace-them online.

Need more local storage for each node ? - you can have a SD-Card slot next to each Pi slot - there are 46 GPIO available pins for those kind of extras (RTC, temperature, front panel leds & reset button for each RPi DIMM)

And Liz just let slip in the announcement comments that Broadcom might enable some extra functionality (ETH, SATA or other fast interconnect) on those extra pins.

Raspberry Pi Compute Module Release

psergiu Re:BUT, More RAM please sir... (51 comments)

The BMC chip can access 1GB of RAM, but unfortunatelly 512MB is the largest size currently produced in that form-factor (Chip-on-Chip BGA DDR1).
And the Raspberry Pi Foundations does not buy RAM chips in enough volume to justify to any vendor a custom made memory chip at that price.
So we're stuck with 512MB ... unless this new SODIMM form-factor is so succesful that they have enough volume to get that custom 1GB chip made for them at the same price as the current 512MB one.

Linus Torvalds Suspends Key Linux Developer

psergiu Re:systemd Architecture (641 comments)

As a sysadmin using RedHat in production environments, i will not recommend upgrading to RHEL7 if it uses systemd as it is now, with no backwards compatibility:

1) We have tons of old proprietary software which only knows about init.d startup scripts, cron & so on. That software will surely not get updated to be systemd-aware by the vendor and we cannot make "hacky" things for compatibility as we lose any vendor support.

2) journald does not support remote logging. When you have servers handling PCI data, you spend more on external hardware & software who make sure all PCI data is protected than you spend on the server itself. No remote logging = no go for systemd.

Also, on a production server, you really don't care if the OS startup scripts run in 1 minute or 15 seconds. You still have to wait 5+ minutes for the BIOS to finish the memory & hardware tests, the [proprietary] DB still takes a lot of time to start up.

Why Your Phone Gets OTA Updates But Your Car Doesn't

psergiu Toyota recall ? (305 comments)

I have a Toyota, it's traction control and all associated assists are acting crazy under certain circumstances (Check Engine light on due to stupid sensor in exhaust pipe + wet road) but i wasn't notified of any recall.
Could this be just for cars that are still under warranty ?
If that's the case, from where i can download the updated firmware and how do i install-it ?

Apple's Hiring Spree of Biosensor Experts Continues As iWatch Team Grows

If it can monitor blood sugar level non-invasively and continuously and can make a iPhone/iPad/Mac do something on set thresholds, i am buying one for my mom, no matter the cost.

I wish you all to never have to witness first-hand a loved one almost dying from an accidental insulin overdose.

Chromecast Now Open To Developers With the Google Cast SDK

psergiu New ChomeCast Device ? (104 comments)

Hope Google releases a better ChromeCast device - with an Ethernet port and support for accepting HDMI-CEC events from the TV so you can use the TV remote to Play/Pause/FF/RW.
The current one is sucky.
And if you are on a metered internet connection, beware: While plugged in, the current ChromeCast pulls lots of large photos to display as the screensaver slideshow. It would be nice if it could be pointed to a local network share to display a slideshow with your own photos.

Must be the SlashCode "asciifier" which removes all non-ASCII characters in summaries and posts, thus mangling a lot of names, locations and math formulas.

Intel Puts a PC Into an SD Card-Sized Casing

psergiu Re:Yo dawg I hurd U like computers... (219 comments)

Something like this is already implemented on HP's PA-RISC and (later Itanium) servers since last century. Go onto the system console, type Ctrl+B and you have access to a small computer completely separate from the main OS and CPU, running diagnostic software which has "probes" on all the hardware buses and components. On the newer servers you can use-it to power on and off various parts of the server, and to enable or disable various busses and connections, allowing you to electrically partition a single server in multiple ones (CPU board 0 + I/O board 0 = 1st server, CPU board 1 + I/O board 1 = 2nd one ...) power them on and access their consoles. Like some kind of VMWare implemented in hardware.

Apple Announces iPad Air

psergiu Re:4K display, anyone? (471 comments)

I am having some memory flashbacks to when people were saying about the same things about USB.

Thunderbolt *IS* PCI Express. Interfacing any PCI hardware with Thunderbolt is extremely simple from the manufacturer's p.o.v. - it's a single bridge chip. Then you use the same drivers you used for the internal PCI/PCIe card.

CherryPal's $99 netbook scam

psergiu psergiu writes  |  more than 4 years ago

psergiu (67614) writes "Hailed everywhere as revolutionary, Africa, the $99 netbook from CherryPal has failed to deliver. At all. Thousands of orders were made and nobody has received yet a unit or even their money back. Max Seybold, the CEO of CherryPal has even started to send threatening e-mails to the owners of blogs with unfavorable comments posted by the users. The only Africa netbook that was supposed to be delivered turned out to be a hoax too.
So, no $99 netbook for us yet."
