Why Ubuntu Linux read only awful crash

I am on my third crash with this . They say it is the not enough space, hard drive bad sector or bad installation. I will tell you Ubuntu Linux is horrible on the recovery. You can only use a live Ubuntu Live CD to recover for back up of filles. You always have to reinstall the operating system which blows. When you do searches on this topic, it appears this is quite common on Ubuntu. When you compare to Fedora, it is not so common. As a result, I am finally switching to from Ubuntu to Fedora since many high speed trading shops use it .

If this a constant problem like I have, you may want to use a new drive. I can onlu recommend Western Digital over Seagate if you will be running this 24 7 days which means never turning it off. Here are some of the reasons and solutions to fix this problem:

Also I choose this Western Digital drive since it s a NAS for 24/7 operational drive https://www.canadacomputers.com/product_info.php?cPath=15_1086_210_212&item_id=063680

Seagate Barracuda or WD red? from DataHoarder

As part of the diagnostics, I found certain drive/USB key/devices which were exluded from the BIOS. Press X to switch between excluded and included lists.

Ubuntu Linux desktop tour with 2 running crypto currency strategies movie

Ubuntu Linux desktop tour with 2 running crypto currency strategies movie

Here are notes types up

Hi there This is a SILENT video of this new Ubuntu desktop environment I have set up 10 days for 2 working strategies with respect to crypto currency

First is the winning strategy

Everything is developed in Python

First strategy resides in 2 terminal sessions within Terminator

The third terminal session to get current profit and loss of the current running session

Now the second strategy, this one resides in another terminal application called LilyTerm

See that I can have tabbed sessions in one windows of the terminal app. Same with Terminator but I use a different app to distinguish the different running sessions

Get it?

Both strategies also run with redis NOSQL

Both strategies connect into the same Redis-Server but different tables distinguish the strategies

Thee older (not newer successful strategy) tables all end in Old

This is the best way I came up with 2 have strategies work within the same system. There will be lots of other modifications but this is the basic set up I got right now.

As for the Redis client, I am still using Redis Desktop manager but it is true open source on Linux (this is running Ubuntu 18.04 which is the current version)

I also have the stand email client like Thunderbird with Firefox the browser. Nothing fancy but it works

Also, I use Filezilla a lot for FTP

Pretty simple description of how this whole thing works together. I could get a mic and audio setup but this is just the basic. As a result, no audio is on the sytsem so I just type like this which means it is silent. Sorry about the typos here but like you care.

That is all byue

Ubuntu Linux desktop everywhere

Ubuntu Linux desktop everywhere

Oh man this is becoming killer.

 
Eveything is ready to run on 3 or 4 dedicated Ubuntu Linux boxes. This includes a dedicted Redis NOSQl. All other run the various Python strategies which will be spanned across various boxes.
It is bye bye Windows and Mac OS eventually !

NAS will be help

5 hr C++ tutorial with Redis Hiredis Redis3m on Ubuntu Linux

Botched 5 hr C++ tutorial with Redis Hiredis Redis3m on Ubuntu Linux

Last week I spent about 7 hours trying to help a Quant Elite member set up his C++ environment properly.

 

Why did it take so long? Well, let me count the ways …

 

If you use Linux, it gets confusing as to which open source integrated development environment (IDE) you should use. And after many hours and bugs, we came to the conclusion we were going nowhere.

 

If you’re a newbie to all this, you’ll almost certainly get some value out of this video.

 

Check out the video here
