Painful Speed for USB Transfers? Dirty Bytes!

Since my upgrade to newer distros, I was suffering from really slow USB transfer speeds.  Copying a large file to a USB stick would take long minutes and, although the process was eventually completed, I needed a lot of patience.

Then, I started trying different solutions but none seemed to work until I found this one.  It was about a problem that was exactly like mine.

It is very simple.  You just need to find the etc/sysctl.conf file and add the following line:

vm.dirty_bytes = 15000000

That's it.  With that, copying a 1.2 Gb file took me about 4 minutes and the progress bar was showing the information fine.

Right, it's not the fastest speed, but at least it is way better than before.

To Everything Turn, Turn, Turn!

After a quick glance to Twine, I started looking for a way to make a book with a flipping page effect.  Some apps to do that are quite expensive!

Finally, I found one that is free and seems very flexible: Turn.

Turn is a small and powerful Javascript library that works with jQuery.

After some experimentation with it, I've managed to make something basic, but useful.

Let's see if I can learn how to use its many features.

In Search for a New CPU

How hard can it be to find a new barebones CPU?  In the past, one could go to several shops and get one.  Today, I  tried to find one and it has been impossible to get one without either Windows 7 or Windows 10 already installed.

The worst part is that they claim that "since Windows comes for free," buying a no-OS CPU would not cost me less.  Really?  Since when has Microsoft been giving away licenses of Windows 7?  Also, I thought that the "free Windows 10" offer was good for a year, only.

The only reason I want a new CPU is because my desktop is 32 bits and the software I must use to complete my taxes runs just on 64 bit computers.

Chromeboxes are not an option because the software does not run on them.

Well... there are still some shops I haven't checked out.  I hope one of them still offers a CPU with a clean hard drive.

If I am not lucky, I guess I'll have to buy the components separately and put together the computer on my own.

What about a Linux box?  I have to check that option out, too.

Ubuntu Listed by Itself on NetMarketshare?

Today I decided to check on NetMarketshare's stats from last month and noticed something that caught my eye:

If you see the last entry, it reads "Ubuntu: 0.63%."

The curious thing is that, 3 lines above, you read Linux at its never changing one point something market share, according to the site, that is. Although, compared to July, when Linux had 1.29%, August's 1.38% is quite a leap.

But why is Ubuntu listed separately?  The page is listing desktop operating systems, so I see no need to separate Ubuntu from all the other Linux desktop distros.

If Ubuntu's share were added to Linux, then the penguin's market share would be 2.01%.

Or am I missing something?  Is Ubuntu using a kernel different from the Linux kernel, for example, and became a totally separare OS?

I guess I have to check that out. 🤔

My Old Samsung Chromebook Is Still Alive!

Yesterday, I took out my old Samsung 500C chromebook from its resting place and turned it on, to see if it still worked.

Well, some keys are not responding, some of them the ones I need to open my session, but fortunately the virtual keyboard helped me with that.

I just want to see if the battery is still OK.  If so, I may use this old timer for one last job.  It is a quite important one, by the way.

It involves LibreOffice, running on Linux by means of crouton.  Fortunately, both crouton and Linux work fine.  LibreOffice is there, too.

Great!  Now, let's see how long the battery lasts...

Making a Cell that Increments Its Value +1 in LibreOffice

Today I learned how to increase the value of an active cell +1 by making a simple macro, thanks to oguillaume, who kindly offered this tutorial for OpenOffice.

This simple macro will add 1 to the value of the currently selected cell (known as the active cell).
This increment cell value macro is useful when associated with a keyboard shortcut for counting things rapidly.

Simply create a new Macro Sub :

  • In the menus, choose Macros > Organise Macros > OpenOffice Basic,
  • In the dialogue box unfold the following hierarchy "My Macros > Standard > Module 1"
  • Now that Module 1 is selected, click on button Edit
  • Copy and Paste the code below
  • Hit Save (Ctrl-S)    
Now all you have to do is Copy/Paste the code below in the editor that opened (the "ThisComponent... +1" is a SINGLE LINE).

Sub activecellplus1

ThisComponent.CurrentSelection.value = ThisComponent.CurrentSelection.value +1

End Sub

 Now to assign a keyboard shortcut:

  • In Menus, choose Tools > Customize ... ,
  • In Dialog, activate Tab called Keyboard
  • Look for an empty shortcut key in the list and select it
  • Now in the list called "Functions, Categories" scroll at the bottom of the list and look for '+ Open Office Macros'. (Click on the + to unfold) Now continue unfolding '+ User, + Standard, +Module1 '
  • Now in the list called Functions, you should see an entry called 'activecellplus1' . Select it
  • Now click the button called "Modify" and then OK at the bottom

Test it:

  • Choose an empty cell or put a value in a cell (e.g. 5).
  • Select the cell (click on it)
  • Now hit the shortcut you have created and see the value increment by 1
That was exactly what I needed!  Thanks!

Electronic Invoices...

I remember that some years ago, I went  into my country's official page to obtain the tools to fill in my taxes.  I was greatly displeased to see that everything was Windows-based.  Not even Mac users had an alternative.  That day, I wrote a suggestion concerning multi-platform solutions, but I did not think they were going to do anything about it.

This year, the government started pushing for electronic invoices.  Thus, I went into the corresponding page to learn about the tools... My first thought was "Windows might be a must."

However, I could not believe my eyes: they had the software for Windows, Mac, and Linux!

Well, Linux 64-bit only, and just Debian-based, but hey, that was great still!

My desktop and main computer is a 32 bit box, so it would not be useful. That did not worry much because I own a Linux laptop that is 64 bits.

Thus, I downloaded the software and tried it...

Success!  I could effectively create, sign and send my electronic invoices! 

I still don't know how this will work in terms of accounting, but I am glad free software users were not completely left behind this time.  

The world is changing!
