Internet everywhere

Schon vor Jahren haben wir uns für ein Internet überall begeistert. Da fällt sofort das Internet in den Zügen der Deutschen Bahn ein, das Satelliten Internet Iridium, Mobilfunk und Wlan Hotspots.

Im folgenden besprechen wir die verschiedenen Technologien, sowie Vor – und Nachteile.

Mobilfunk ist spätestens seit dem es Flatrates für 4GB Daten gibt, sehr verbreitet. Diese Technologie hängt von der Verbindung zum Funkmast ab. Falls Bäume, Beton, Metall doer andere Materialien die “Sicht” zum Funkmast versperren funktioniert die Verbindung nur langsam oder gar nicht.

Wlan oder Drahtlose Netzwerke

Seit der Verbreitung von Smartphones sind Drahtlose Netzwerke, Hotspots und Wlan sehr verbreitet. In den meisten Bahnen, am Flughafen und in Restaurants kann man sich per Funk verbinden.

Übrigens war das erste Allroundsystem Blackberry, dann Nokia und erst dann Android von Google. Parallel hat sich iOS von Apple, aber nur auf Apple Geräten durchgesetzt.

Price of ext4 file recovery

This is an article which is valid for Germany and the people’s Republic of China

We charge according to the type of fault and the time and energy spent on recovery. Fault types are generally divided into logic fault and hardware fault.

Logic failure: deletion, formatting, partition loss, file opening, garbled code, etc. the same is true for ordinary office files. If there are no fragments, the price is two or three yuan. For files with special structures such as database files, the price is not only these. The file structure is different, the storage principle is different, and the difficulty is different. Database files are often edited, so many fragments will be generated, which need to be scanned, reorganized and repaired by special tools.

Hardware failure: hard disk circuit board is broken, bad track, head damage, firmware problems, etc. Generally speaking, firmware is equivalent to a computer operating system, which controls the work of the hard disk. For example, in the event of Seagate’s firmware door, some of the hard disk was damaged due to the design defects of the hard disk. Some of them were caused by the hard disk hitting the firmware area, and others were caused by bad roads. Charges vary according to the difficulty

Opening: 1. When opening the hard disk to replace the magnetic head, a magnetic head of the same model is required as a spare part. This is the cost. Now generally, the data is recovered and charged. If it fails, the merchant will lose a disk.

2. Technology: opening requires skilled operation. In a dust-free environment (many data recovery companies in China use a dust-free workbench) and many hard disks can come out without replacing the head data. Some firmware areas are damaged and the disk surface is scratched (I would like to remind you that when the hard disk is powered on, it makes a strange noise and cannot be powered on repeatedly), it requires more time, energy and spare parts.

3. Operating costs of the company: equipment, rent, engineer’s salary, promotion of a search engine, etc

All the above are common disks. The server disk array is generally charged according to the number of disks, operating system, RAID level and damage degree.

Specific problems are treated in a specific way. In many cases, the difficulty of failure is different, and the price will fluctuate

Arcam 850 has bad sound and picture

As my father is a fan of high fidelity audio equipment we change receivers and equipment every now and then. We first purchased an Arcam 600 from a dealer and as an upgrade bought Arcam 850 from Ebay classifieds.

With Arcam the sound was very bad and the display over HDMI on the projector was not colourful. That’s why we decided to do a software update.

The only problem with this update is that you have to have patience. using the standard update tool shows no signs of progress, although there are any. Here we used Serial Port monitor, the trial version.

Both pieces of software are below. Note: As the serial Port Monitor is not software for everyday usage, it is not included in our Capsis Installer.

Takes more than 10 min. for convenience use the software Serial Port Monitor

Serial Port Monitor download

A side note is that someone tried to cheat us selling the Arcam for a lot less than it is worth using a fake German id. We contacted the person and she told us that she reported the case to the police. To protect her and because I am not (yet) a forensic expert I will not publish any headers.

Our current Setup is Hewlett Packard+Dac 8 DSD + TA 3100 HV A + TA 3100 HV A + TA 3100 HV V

Education of Children

Our company has recently held a summercamp in the Luther Academy for children to learn English. We read a lot and did some funs stuff with IT, Computers and Raspberry Pi.

Every child was given a certificate depending on his or her ability. The software used to create the pictures was Painstshop Pro 9 because it is faster and smaller than Photoshop, besides it runs under vine with some hacking.

We chose Dr. Seuss to read. The books were quite new for the children back then, for our children it is a mixed experience. While some are excited, others think that the content is no match for our digital gaming/entertainment experience.
One of the common things I noticed is that Dr. Seuss, who is a Swiss Immigrant, uses rhymes, as Die Häschenschule.

A robot was created on basis of the Raspberry Pi B plus- Here you can use any model but be sure to have it with wifi on board or with a wifi dongle
Then a cheap clone of the Arduino board with a GPIO Header controlled the motor.

The result is a robot car, that can produce tones – Any midi will do like do re mi to brother John – can move in any direction you want it to with any speed you want it to and do some more fun stuff.

You access the robot via Wifi and SSH. After you are in the system, you can write and execute you own Python code. One of the common errors is that the “block is not indented”. One of the ways to solve this issue is using another editor. For instance use gedit on Linux and rewrite the code.
