Backups are useful!

I decided to do a hardware upgrade and change the OS to Linux Mint 18.1 (with cinnamon). I wanted to add a 128GB SSD I’d purchased 4 months ago and put the new OS there. I’ve got a sata 1TB boot drive, /dev/sda and 250gb sata in /dev/sdb and a 1.5 TB usb drive for backups on /dev/sdc. The new ssd showed up as /dev/sdd – Now the tricky part: /dev/sda and /deb/sdb have LVM managed partitions.

When the install of Mint 18.1 was finished I saw that it wrote the grub boot stuff to /dev/sda –No No! But it did. I wanted to set the bios to boot from the SSD (dev/sdd) – not going happen my way. One other side effect – when booted into Mint (/dev/sdd) – it can’t see /dev/sda LLVM partitions which is everything important to me! I’m running in LVM group vg--mint and the other drive is group vg--ubuntu. I have yet to find the magic LVM commands to access that other group. But I have that usb backup and it’s current for all my user directories. Getting those backup directories copied properly took a fair amount of time, trial and error.

I can build Shoe3 (minlin) on Mint. It took a while to get Exim4 smarthost working so I can send email from cron or command line. I use the tt-rss newsreader many times each day and it is one diffcult install – apache2,php,mysql or postgres and tt-rss which has a lot status messages about what’s not working — kudos to the author/s

I don’t have the Oraclebox VM’s those are on the unmounted sda/sdb volumes and there are potentially viable setups on the backup drive. I’ve sure where the chroots are but It might be a good time to fix them – I only need one for x86_64 and It could be a more modern version of Debian – maybe only two years old instead of four+ years old. Probably a good thing but it does take time if you don’t remember much about the last time you did this.

Forgot to mention – that SSD is fast. Boot’s Linux minutes faster. Hardly any delay when launching apps – You want one. Maybe I should get a 250GB SSD and stuff it where /dev/sda lives? Maybe, probably not unless …

Shoes 3.3.4

Yup, another Shoes release. What’s New? systray. Moving and resizing windows. You can disable the image cache for the whole app or per image. Other than that there’s some bug fixes and some Shoes developer love. We also don’t support 32 bit linux anymore (it still builds if you really need it and are willing to do the work) We added FreesBSD 11.3 (64 bit) as a native port if you have the proper ports installed.

ChangeLog:

=== New with 3.3.4
  * Uses Ruby 2.3.4 (2.3.3 on Windows) and Rubygems 2.6.12+
    https://github.com/Shoes3/shoes3/issues/361 and
    https://github.com/Shoes3/shoes3/issues/270
  * New widget! - systray sends tiny status messages to the 
    host OS desktop.
    https://github.com/Shoes3/shoes3/issues/363
  * New platform - freebsd 11.1 (64). Can build, run, install and package for.
    https://github.com/Shoes3/shoes3/issues/365
  * Dead platform - 32 bit i686 (Linux intel) target is no longer supported
  * libcurl.dll/dylib/so and new gems are included with Shoes. require 'typhoeus'
    to use it. When net/http and open_uri is too confusing, arcane and limiting. 
    On Windows it's not faster (or slower) - just better in other ways. 
    see https://github.com/typhoeus/typhoeus
  * Method app.resize can programaticly expand the window.
    see https://github.com/Shoes3/shoes3/issues/370
  * Windows can be positioned 
    https://github.com/Shoes3/shoes3/issues/28
  * can enable/disable image cache
    https://github.com/Shoes3/shoes3/issues/323
    https://github.com/Shoes3/shoes3/issues/377
    See Advanced->appmethods in Manual.
    
=== Fixed with 3.3.4
  * When Shoes is installed on a system with existing rvm/rbenv it
    might use the wrong set of gems. 
  * Fixed some SSL issues for download and image (Windows).
    Ruby/Windows (net/http) ssl problems remain unfixed.
  * Improved Windows downloading speed - still sub-par but better than
    before. 
  * some downloaded images don't have an etag (cough, manual Image example)

=== Developer issues with 3.3.4
  * rake does a better job of dealing with changes in lib/shoes/*.rb, static/manual-en.txt
    and changes in samples/*/*.rb. You can change these without a full rebuild.
    https://github.com/Shoes3/shoes3/issues/362
  * new freebsd target (loose and tight shoes)

Other than that, nothing new. 🙂

3.3.4 beta – systray and

I’ve got a set of betas for 3.3.4 for windows, osx, pi and x86_64 linux. Here

You might notice that there is no 32 bit linux – why bother? It’s pain to support and nobody uses it. OSX Mavericks (10.9) is also likely to disowned in Shoes 3.3.4. It’s a real pain in the ass. That will not happen soon. But, it will happen.

What’s in Shoes 3.3.4 beta this month?

  • Systray
  • Typheous
  • A hack to get https urls working for Windows and OSX image and download methods.
  • Windows GUI speed improvements in general, most certainly for network things. Still too slow but a whole lot better that 3.3.3. Moves the meter from ‘really sucks’ to ‘almost doesn’t suck’

It’s highly likely that Typheous will be the recommended replacement for the use of net/http and open_uri when Shoes download is insufficient for networking needs. It’s a lot more understandable to programmers who need more than what Shoes download can do. See the README.md. Improvement? I think so.

The download performance and general friskiness of 3.3.4 on Windows is noteworthy. Sucks less and I think we could do better. There are SSL reasons and ruby-bugs why you don’t want to dig into net/http and open-uri

Quick look Shoes 3.3.4 – systray

Shoes 3.3.4 will probably have a systray pseudo widget. Beta for Windows for feedback. You can read the manual which has this test program

Shoes.app do
stack do
para "Press button and look in your systems notification area"
ctr = 0;
button "Notify" do
ctr += 1
icp = ''
if ctr % 3 != 0
icp = "#{DIR}/static/shoes-icon.png"
else
icp = "#{DIR}/static/shoes-icon-red.png"
end
systray title: "Notify Test", message: "message ##{ctr}", icon: icp
end
end
end

Closing in on 3.3.3

There are Shoes 3.3.3 beta’s to download from and the Change Log is here.

What you don’t know, behind the scenes. It was a lot of work from core contributers and myself. And then some core panties got twisted too tight to work together and now it’s just me working on the C side of Shoes. I miss them. I’ll work through their bugs reports and suggestions as best I can because they are good things to do.

Cleanup can be endless

After @backorder moved the Shoes C code into a more logical configuration and I changed the rakefile mess to leverage that – It’s quite developer friendly now if you are of the C persuasion. Most Shoes folk will never see those changes and that’s OK with me. It was something that just needed to be done.

Turns out there is another task that ‘just needs to be done’ – cleaning up my computers by removing all the useless junk I have gathered over many years. Some junk was shoes related and some were just grand ideas I got involed with Shoes. I have a soft spot in my heart for the Raspberri Pi so I ordered an SSD and that board didn’t work, I ordered some more parts to make the ssd work in the main box because good money needs more good money and and then some more parts and then some head scratching on making all these Chinese adapters work and I was pushing GB’s of data around which is kind of slow.

I’m not done yet but I can see the light at end of the tunnel. It just needed to be done.

Is Shoes weird?

More than you know! I get annoyed too, just like you do. Thinking about changing languages? I do. At a very recent Linux conference was this gem of a presentation about quirks in various languages. It’s about javascript behavior but she beats up all the popular kids along the way so that’s fun. 40 minutes of light hearted humor will be good for all of us. Recommended.

Free At Last! Shoes 3.3.2 has been released.

Yes, it took forever and it’s not perfect but we could wait forever for perfection. Shoes 3.3.2 has some fun new features and some bug fixes. Available via at the usual place.

    New with 3.3.2

  • Ruby is updated to 2.2.6 (windows still uses 2.2.4)
  • gems is updated to 2.6.8
  • Profiler with both a GUI and the more traditional text report.
    Written in Shoes and Ruby so you can modify it if you like.
    issue 232
    Wiki – how to use
  • Shoes.show_console is now Shoes.terminal with many options for size, and
    colors. It can handle some common escape sequences (colors and bolding)
    On Windows:
    Use Msys> cshoes.exe
    or install one of those ANSI dll things for your DOS era console.
    Rumor: Win 10 does support ansi escape sequences on it’s console.
    Sometimes Win7 does ok with some escape sequence.
    On OSX – scrollbars might not show up. page up/down keys and home/end
    and scroll wheel do work.
    Useful for running unit tests of Shoes and other terminal stuff like the
    profiler text report.
    Note: raspbian may have font issues for ‘monospace’ font.
    issue 236
    issue 256
  • exit should no longer be used. Please use Shoes.quit
    issue 263
  • plot widget (line,bar,scatter, pie charts and radar/spider)
    issue 288
    issue 264
    Wiki – how to use
    expect some confusion and bugs.
  • rename method ‘refresh_slot’ to ‘refresh’ before too many people
    use the old name. This could break some scripts.
    Fixed with 3.3.2

  • Radio buttons fix
    issue 274
  • A new launch script for OSX (cshoes) that works like Linux and Windows
    from the command line. Use Cobbler to create your osx cshoes script.
  • Windows: bug261 – fix font loading
    issue 261
  • debugging with byebug is much better.
    issue 263
    Wiki – how to use
  • fixed: click and release methods return the documented button. top, left
    values. Button numbers start with left button = 1 and increases from there.
    How many buttons and how they are numbered is not something Shoes can know
    about so it’s the user responsibility to be cross platform with buttons > 1.
    issue 240

State of the Shoes Address

You may have noticed that it’s been a while since Shoes 3.3.1 was released and 3.3.2 keeps getting pushed into the future. What’s going on?

Well, some of the new features are very difficult to write and time consuming to test. We’ve discovered some very difficult issues with packaging for Windows 10 and so far, there is no way to get around what Microsoft wants and what I’m willing to do to Shoes, or what your willing to do. It’s called “code signing” which requires the annual purchase of a certificate (and the price can be very high with some certificate authorities). I won’t pay for that and I don’t think you should either.

The ground shifted and all we can do is adapt. Don’t package your scripts in an exe! Just tell your Windows users to install Shoes first. Then run the .shy you created.

Ruby also shifts under our feet. As Ruby evolves, they change things. Some of those changes will involve a lot of work for the Shoes C code in the future. I just found another problem with Ruby 2.2.6 (can’t cross compile the fiddle gem for Windows) – that will slow down building and testing even more if it can’t be resolved. I also found a new dependency problem last night for Windows but that should not be too difficult.

And then there are the Shiny Things that may not work, but consume lots of time to discover if it’s a failure or a brilliant idea. Like ebook

Yetta Another Beta

This one might cause some problems because it fixes a problem where the code didn’t do what the documentation said for some click and release events. The docs say to deliver |btn, left, top| to the proc. They didn’t. From what I can tell, they never did.

We also accept/present more button numbers instead of is always “1”. Button numbers start at one and increase from there in some pattern only you and your mouse device know. Cross platform? No! Your problem to sort out if the wheel click on OSX is a different number on Linux. Most people will stick with not caring which button. Now you have options.

If you’ve worked around the lack of |btn,l,t| on click and release then you may want to test your scripts with this beta. In this case, the documentation says the right thing and the code was incorrect. Long time wrong. See here

The beta also include the latest, almost nearly OK, plot widget.
