When will Google update kernel in Chromebooks

In the light or latest vulnerabilities found in Intel, AMD and some ARM processors found by Google researchers, everybody has summoned to create and install patches and fixes.

As an owner of one ARM Chromebook  currently running Linux Kernel Ver. 3.14.0 (Chrome OS after all updates installed) I am not sure whether it is subject of Meltdown and Spectre vulnerabilities, but according to Kroah-Hartman one of the main Linux kernel maintainers:

“If you rely on any other kernel tree other than 4.4, 4.9, or 4.14 right now, and you do not have a distribution supporting you, you are out of luck. The lack of patches to resolve the Meltdown problem is so minor compared to the hundreds of other known exploits and bugs that your kernel version currently contains. You need to worry about that more than anything else at this moment, and get your systems up to date first. Also, go yell at the people who forced you to run an obsoleted and insecure kernel version, they are the ones that need to learn that doing so is a totally reckless act.” read more

Switching to Raspberry Pi 3

As my server was running on A20-OLinuXino-LIME board, it started to freeze. I thought it is software issue and after some update it will be fixed, but that didn’t happen. When freezes even blinking LED stops blink.

So I decided to try Raspberry PI and installed Raspbian OS. No SSD disk as before, all running on micro SD card.

I am playing wit Pis for a long time (my first one is Rpi 1 Model B still running my weather station on the balcony).

Here I am – my blog on Pi, so far so good, will see. read more

My Accounting program

I’ve made a program for tracking my finances. It is not a big deal, but it does the job for me.

It is web based, works on top of LAMP stack (Linux, Apache, MySQL and Php).

You can try it – the code is available at: GitHub

The install:

1). Drop the source code in a folder at Apache’s document root:

git clone https://github.com/jet-/tinyacc

2). Create a database in MySQL (for example acc_usd), and change the conf.php file accordingly.

3). Tables creation – run: read more

Счетоводната ми програмка

Ransomware and Munich

In the lights of recent worldwide ransom-ware attacks- Wikipedia to computers in Windows world, I am wondering what happens to the process of migrating back from Linux (LiMux) to MS Windows in Munich City Government. As you probably know they managed to switch 15,000 desktop PCs from Windows to Linux and running fine for more than 10 years. Some local politician decided to go back after an offer from Microsoft to switch to Windows 10. Coincidentally Microsoft’s head quarter moved to Munich around the same time. read more

My new Chromebook

I bought an ASUS Chromebook Flip 10.1″ Touchscreen Laptop (Quad Core, 4GB, 16GB eMMC) – Aluminum Chassis. I know it is like a dumb terminal (browser), but as a Linux fan my intention is to install Linux on it. Boy that thing is thin – love it.

  • With 10-finger touchscreen, ASUS Chromebook C100 can be flipped over from 0 to 360 degree, using it as a Chromebook, or a tablet.
  • Quad-Core ARM 1.8GHz processor with 4GB RAM, Wireless 802.11 A/C
  • Built with aluminum chassis, 10.1″ HD IPS Display 1280 x 800. HD Webcam
  • Run android apps

When start it Chrome OS comes in no time. You have a browser and all Android apps in your disposal. read more

3.5 inch Touch Screen Display For Raspberry Pi 3

LinuxCon 2016

Tomorrow Linux will turn 25.

There is a LinuxCon event in Toronto and I decided to visit it and see Linus’ keynote. What a disappointment was as per schedule it suppose to be like 10 minutes long. On top of that they asked me to register and pay $100. I will pay… but some other time (never). I am not interested in corporate drones there and their containers (most of the topics of the conference). VMware, HP, IBM and surprise Microsoft and Citrix (WTF). MS even has a keynote. Some memberships are $1100 – good luck with that. I don’t make my living with Linux or containers. That explains why Linux desktop is going nowhere – there is no money in it (for FSF). read more

Measuring Temperature and Humidity with Raspberry Pi

After I played with OLED display with Raspberry PI, the next logical step is to display more useful information on it.


I bought a sensor DHT22_AM2302 which is a Digital Temperature Humidity Sensor with serial interface.

The device measures both temperature and humidity and you get the values in single poll.

Connected GND to Rpi’s GND,

Vcc to Rpi GPIO- pin 2 and finally

Data to GPIO pin 8 (GPIO 14)


Little bit of coding in Python and using nice libraries written by Tony DiCola for Adafruit Industries and here is the result. read more

Windows 7 updates stuck (or suck)

I did fresh install of Windows 7 on both bare metal PC and in Virtual machine. Install went ok, but no updates. Checked for updates – 4hrs and still “checking…” I interrupted it.

Found a tool on the MS site which suppose to fix the problem: http://go.microsoft.com/?linkid=9767096

10 hrs later this tool is still “Checking for updates”

Mind you that this is complete fresh install, without any 3rd party software installed, even no antivirus program.

Not sure if MS is crippling W7 to push everybody to W10 or is plain ignorance and incompetence. If there is a problem with connectivity or some server is unavailable – how hard is to check that and say so. Could be some system file locked by another part of the OS – I am speechless. read more
