MAID == Massive Array of Internet Disks

SAFE == Secure Access for Everyone

In ze Internets people have been watching this endeavour by the brave Scots very very carefully and keenly for a few years. If all goes well MaidSafe.net will make the current Internet the “Legacy Internet” rapidly by providing a shared digital commons wealth unseen before. https://forum.safenetwork.io is the community forum where you can catch the gist of how excited people are about MaidSafe Network and it’s significance to the future of population of Planet Earth.

Technically this endeavour is very bold and ambitious. The key people have donated all their patents, papers and code to the nonprofit MaidSafe Foundation though there is also a MaidSafe Ltd registered in Scotland to enable professional staff for the ongoing development and deployment effort. Funds were raised by selling off 10% of the ceiling of SafeCoin (cryptocash) amount (4-gigacoins) to an enthusiastic crowd. So you get the gist that these are highly creative individuals pushing the envelope onto the future.

Last week http://maidsafe.net/ published it’s first downloadables that allow people to discover the MaidSafe test network. Word of caution: The test network is wiped occasionally when required by devops.

MaidSafe Launcher 0.3.0 – This is for connecting to the network – The login consists of three things: a pin, a keyword and a password. I don’t fully know what is the purpose of the “keyword” and the test network is getting reset whenever necessary for development and the credentials stop working because the secret identity that allows you to access your public identity no longer is there in the testnet.

Choose Pin, Keyword and Password to make anonymous identity on the network that you can bind public ids and services to

After entering the credentials the Launcher will log on to the network to act as a gatekeeper to apps that want privileges to touch your public and private directories and files

Now start the MaidSafe App and it asks the Launcher to ask you for privileges.

MaidSafe Demo App 0.0.1 that enables

  • Creation of Public ID that allows people to reach your network attached public services / sites and also
  • uploading public site / service to the network ( requires the DNS hacks to be viewable outisde of the Demo App )
  • uploading and downloading private directories and files

…

TODO: Install the DNS hacks and try those out and report here

Laptop temperature problem solved by high pressure air into the heatsink and some learnings of factors of heat management

System monitoring and control software for [K]ubuntu / copyleft

Resource Monitor
Resource Monitor seen in 2x high panel height

Resource Monitor is a KDE5 Plasma Plasmoid Widget companion to the System Monitor. Install instructions in Muon Discoverer. One dependancy must be installed. It sits in your panel and reports CPU load and frequency, RAM and swap usage  with tiny letters and numbers and graphics. Here seen in 2x high panel height

Psensor Psensor-rational-readingis a copyleft program, specifically GPL licensed  installable from the ubuntu repositories with ‘sudo apt install psensor’

Cpufrequtils (ThinkWiki entry for cpufrequtils)are installable from the Ubuntu repositories by typing ‘sudo apt install cpufrequtils’ and contains 2 commands:

  • cpufreq-info for querying the state of the cores and
  • cpufreq-set for setting parameters.

Thinkpad Fan Control is a fan RPM control software written in C for the Thinkpad series of laptops. Apparently the normal controller has a ceiling at 4,500RPM but according to the internets the fan can be instructed to go 5,500RPM raising the noise pitch and volume slightly.

 

System monitoring software for WindowsCore Temp screenshot

Core Temp is a freeware Windows program and reports real time temp sensor data ( prlly algorithmically smoothed but much more stable ) and real time CPU frequency multiplier and frequency reading.

CPU-Z by CPUID is another good free-of-charge CPU-Z screenshotWindows program that will give you lot of information about your system also including the frequency multiplier used at each time

 

 

 

 

 

 

 

Synopsis of the original problem

Psensor displaying problem temperature
Not like this. Psensor showing temperatures where the user is susceptible to system shutting down because of a trigger temperature has been reached or exceeded

 

 

 

 

 

Had a machine with a weird temperature problem here… It’s a 2011 Lenovo ThinkPad X201 with a 1st generation i5 known as Arrandale. CPU temperature control, maybe voltage control, maybe amp control is not working correctly in #Kubuntu. (UPDATE: Sandy Bridge, Ivy Bridge and newer intel systems should use the Intel P-State governor. Installation instructions for [K]ubunu here)

Temperature seems to be mostly dependent on the frequency of the CPU with some correation to load. Reported CPU fan rotation speed is 4,000-4,500 RPM and does not adequately respond to the heat situation.

(UPDATE: Directing high pressure pressurised air into the cooling elements while machine unpowered seems to have remedied the problem.)

#GNU/#Linukka heat shutdowns causing system being unusable. Before anyone starts about the GNU/Linukka treating the system and therefore the user more badly then a Microsoft Windows I must say that air conducts have not been cleaned and silicon heat paste has not been changed to fresh, new. I gonna get supplies to do that when I run into shop.

In Kubuntu15.10 GNU/Linukka burns the chip at ~ 90C ~ 2.0-2.5Ghz operating speed causing emergency shutdown because of temperature because the readings viewed in Psensor may flux 15-20C somewhat interdependent of CPU load. Windows 7 keeps the CPU ~ 1.5-2.0GHz quite independent from the load and the temps are in the acceptable ~ 70C zone with only 2-4C variance in the readings reported by CoreTemp.

#Solution:

* Bought a pressure air can and blasted the visible from exterior heat sink
