Dissed by hashcat for using GTX 650 Ti

Not good enough?

For fun and my curiosity after installing an Nvidia GTX 650 Ti on my old totally outdated system (DELL Optiplex 780), I wanted to do something that would actually use this "GPU". I don't do 3D games at all and have never done it before. So gaming was out.

Then why not do some hacking (or cracking) using this GPU's computing power? I thought.

I installed Nvidia driver and CUDA toolkit on it (under Kali Linux) and following the instructions available on YouTube, I began brute-forcing my own router-modem (Huawei's old model).

Everything seemed to go well until I ran hashcat to brute-force the hashed file. The process almost immediately quit with some messages. WTF?

I read the messages and learned that I was not good enough. My Nvidia GTX 650 Ti was not good enough.

Basically it (hashcat) complained that the CUDA support level of mine was 3.0 and it expected at least 5.0 support.

So I can not even brute-force anything at all. Am I going to buy newer graphics card with newer GPU chip on it? No way!

The recent trend of mining boom for cryptocurrency has made the prices of graphics card rise and I won't be able to find any good prices for decent (and maybe used) ones at all. Forget it! Just forget it!

Just out of curiosity, I DuckDuckGo-searched recommended GPU chips for hashcat and learned that Nvidia GTX 1050 Ti was one of them. How much does one cost these days amid cryptocurrency mining fever of late? Whopping 500 euros more or less!

Garuda Linux and dash cams

Garuda Linux

It is like Ubuntu but based on Arch Linux distribution. Ubuntu is based on Debian distribution.

I have never used Arch Linux before.

As Ubuntu, Garuda Linux has many flavors, in other words, Garuda has many different looks using various desktop environment sets. Gnome, KDE, Xfce and others.

I took a look at its official site and understood that it would be easy to install Japanese Input Method (like mozc, I hope) because there was a screen shot where I saw "あ" (a Japanese letter -one of many phonetic letters that translates into "A" in most Western languages).

This distribution's suggested system requirments are a bit higher except for some of its variant where lightweight desktop envirnment sets are used, of course.

Its policy says the unused RAM is wasted RAM. It is true in a sense. Garuda Linux uses a bit extra RAM to cache more in the RAM to make the desktop operations snappier.

Should I give it a try in near future?

It is appealing but it is only my curiosity that I have never used any of Arch Linux distributions. Or is it because some of the desktop screen shots look so appealing? I have to remind myself that looks are deceiving.

Ding Ding Pai or DDPAI dash cams

Currently I am using VIOFO WR1 so some time. It has served me well and it really saved my life once when I successfully recorded a BMW 1 series model and its driver who hit my MX-5 and ran away. I went to the local (French Police where the accident took place) and filed a report and submitted the video. The recording did not actually include the incident as I had killed the engine before it happened as we were sitting in a total standstill where the roads were still closed after a stage (Tour de France). The recording showed the license plate as I had followed her car for a while before we both entered a roundabout where the traffic got to a total standstill.

I could not have caught her without the recording as I had never paid any attention to the license plate nor had I memorized it even if I wanted in a flash of moment when she attempted to flee.

I am currently looking for another one as a second backup camera or a rear view recording camera.

It has to be inexpensive to begin with. Eventually I found these dash cams from DDPAI.

First I thought I would opt for it basic "mini" but its prices (from various sellers) were a bit unstable (inexpensive seller's stock went out as expensive seller's price is more than other dash cams with more features). This model entered the market around 3 to 4 years ago as some of ther review videos on YouTube are as old.

Then I found DDPAI Mola N3 model. It must be relatively new (reason ditto). A GPS module is available. It is relatively small and the price is also not so high.

It does not have a LCD display built in so all the operations (like changing settings or viewing and managing the footage) are done on a smartphone or tablet with an dedicated app (iOS or Android) like my old VIOFO WR1.

The "mini" model was much smaller and one of its features (not many) that I liked was it ability to rotate its camera so that it can record front or rear without messing with the adhesive foot on the windshield.

The Mola N3 can not rotate but flip. The foot (which includes the GPS module) connects to the camera body with USB C style plug. As the USB C plug does not have sides, the camera body can flip (turn around).

I was thinking of installing one on the wind deflector which is located in the back of my right shoulder.

When the roof is covered on my Mazda MX-5, the rear view is really limited. When it rains, you can forget about recording the rear view through the glass pane as it does not have a wiper.

Currently the WR1 is neatly tucked behind the rear view mirror in my point of view. I don't see it in action. I wanted it that way. No obstruction, no distraction. I wonder the Mola N3 can be as discretely coy as WR1. If it is I may install Mola N3 in front.

VIOFO WR1 can be used on the wind deflector but it may require some kind modification as most dash cams are designed to stick to a windshield that has about 45 to 60 degrees of slant angle.

Parole media player or VLC

Parole or VLC
I am writing this in Kali Linux so I can not write in Japanese. Lately I am using Kali Linux more often than Ubuntu Studio because VLC on Ubuntu Studio won't play some (or many) mp4 files but Parole on Kali does a beautiful job of playing them back. I like watching movies while writing.

I don't know why VLC fails but it does. It did not when I was using 20.04 version of Ubuntu Studio but 20.10 changed the situation.

The Wolf of Snow Hollow 2020

I saw another Werewolf movie just recently "Wer (2013)".

This one was better than Wer in many respects.

This one has more suspense, more human drama and less supernatural stuff.

commercially not viable

In Saxophone world, I guess Selmer stands out of all other brand names.

Yamaha, Japanese musical instrument manufacturing giant (?) also makes them but as long as the production makes profit. This is typical of big company policy. In other words, they make only Soprano, Alto, Tenor and Baritone Saxophones who are used more frequently in bands.

Yanagisawa, Japanese artisanal company also makes them. They also make Sopranino, which is not so frequently used.

There are Taiwanese companies (or a company) and continental communistic Chinese companies who makes them in mass either in their own brand names and sell them under other's brand names (including the unsolicited way like branding them as Yamaha or Yanagisawa so that they sell more expensively).

There are Geman manufacturers. At Julius Keilwerth or Benedikt Eppelsheim. Julius Keilwerth they make usual 4 kinds whereas at Eppelsheim they specialize in ones that other commercial makers won't; Sopranissimo (Soprillo) Saxophones and bigger (lower in tones) Saxophones.

There could be other makers but I am not a specialist in this matter.

The one I acquired (still on my way to me) carries an Italian brand name but I am sure it was made in China (I don't know which, Taiwan or the other). It says Rosetti Series 5. I looked for Rosetti brand name on the Internet and found they are still operational in Italy but their current product line does not carry Sopranino. I think they dropped it as they were not making money on them (lack of demand).

I presume that Taiwanese companies have way better manufacturing skills and I hope mine was made there.

The UK seller (on eBay) says he had acquired it several years ago.

There are two distinct types of Sopranino Saxophones on the market. Two types of design. Let's say they are made after Selmer Mark VI and Selmer SA II. They look different. SA II models have more keys and "improved" table keys (left pinkie combination keys) .

Yanagisawa's Sopranino is anMark VI style model. Chinese models are made in both styles.

I find a lot of brand names seemingly made in China. Many people have made YouTube videos reviewing them. Some brands seem to be better than others.

The seller claims that his (or mine now) is beautifully preserved (the lacquer holds 100 %) and plays well from bottom to high end.

Mine is a Mark VI imitation model. I used to think that the SA II model looks aesthetically appealing but lately the simplicity and tacitness of Mark VI style is not too bad.

Snow fall in Luxembourg and grub

February 8 and 9, 2020

I knew Today (Feb. 9) would be cold as the weather forecast had told me the day before. It seems that the cold air from the west has come. This cold air seems to linger for about a week.

The previous week (or two weeks) was rather warm (around 10 degrees Celsius) and I had hoped that no more cold wave would arrive.

Naturally the moisture in the air had built up and had been trapped as the sky had been covered by grey murky clouds. So the cold air made the moisture fall in the form of ice, which we call snow. It is not like we had a steady snow fall but the moisture in the air fell. We had a thin layer of snowy ice on the ground.

I took a walk through the forest to a supermarket where I wanted to buy Hannah's food. I took a different path on my way back through the forest. People were jogging there.


# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.
# For full documentation of the options in this file, see:
# info -f grub -n 'Simple configuration'

GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`


This is the beginning of the original /etc/default/grub contents. There is a very important piece of information. From the console prompt you can get the idea of how to modify the file when you execute the command "info -f grub -n 'Simple Configuration'.

I modified two lines.


The first modification makes the hidden menu appear when the computer boots up. This is equivalent of hitting "SHIFT". GRUB menu appears and I can choose what to boot.

The second one makes the menu wait for 5 seconds before atutomatically booting the first option.

These should suffice.

VLC woe

The VLC (media player) on Ubuntu Studio 20.10 is having problem playing back some of the mp4 files. I looked up on the Internet (DuckDcukGo) and found a lot of people are asking the same questions on other versions of Linux or Windows and so forth. I tried some of the remedies suggested all in vain.

Now I am using Kali Linux and its media player (what's the name?) to play those movies. All right it is not a big issue.

CPU usage

I found out that one movie file (mp4 but not H265) uses the CPU around 40 %. It is not encoded in particularly a high resolution. This struck me as odd. A movie file encoded in much higher resolution normally uses only less than 10 % of the CPU power. Intel Core 2 Quad (Q9500) is an old dog but still decodes most of the movies with much ease. Why?

Sosumi and camera devices

Dell Optiplex 780 (No HDD / No Memory)

I am waiting for it to arrive. I have to buy SATA to 6 Pin adapter cable to accommodate a graphics card that requires an additional power source to operate.



I may have a shot at it when this Optiplex 780 is settled.

A camera device is wanted

iPhone 12?
