.Net decompilers for linux

 May be you think is a command line tools and you are right. I only can add, it is possible to run GUI for some decompilers using wine. To do this you need to setup .NET 4.7 and .NET Core 3.1 in wine prefix with winetricks utility.

DisSharp works great, but do not forget to change fonts to available:

Kaliro have missed fonts setup from the box, but classes are listed:

Gallium is a remedy for my old Chromebook Lenovo x131e

I have Lenovo x131e for me, but I can not setup Chromebrew even with old version. Chrome Os is a pleasure but I need to update. So that, I spend time to disassemble my device and disable write protection with switch. The only way to change firmware on Lenovo x131e is instruction:

sudo mount -o remount,rw -io exec /home/chronos/user/ 

sudo ./flashrom -r x131e_chromeos_original.rom

flashrom v0.9.4  : bc6cab1 : Oct 30 2014 07:32:01 UTC on Linux 3.8.11 (x86_64), built with libpci 3.1.10, GCC 4.8.x-google 20140307 (prerelease), little endian
The Flash Descriptor Security Override Strap-Pin is set. Restrictions implied

That's all, you can prepare Galium USB stick and boot. But pay attention, F12 does not present and you need to remove SSD from device for first test run. Initial date is in distant future, so change it back to present to connect to Wi-Fi

This update dive me a chanse to run github.dev editor for my public repositories. I wish I can edit my code even from my old chromebook with Gallium and Chromium in the future. But for now it has error

Bigger and shrpener

 I can recommend two online tools I am using to obtain super resolution and remove blurry in images.

https://bigjpg.com/  - is for super resolution

 

this tool for restore photos in mouton also help with  sharpness:

.NET Upgrade Assistant

 This evening I have found win-image-crawler have no ability to write long path for a destination in Windows. But I need a test data for tomorrow morning. It could be possible with Linux, but original crawler tool have .Net Framework 4.5 project type. After MSDN answer I got new tool, saver of my day:

.NET Upgrade Assistant

The result Is excellent, the tool also port all packages with right .net core versions:

Of course, It ask me 10 questions (I answer with defaults for me),  and also it produced .NET 5.0 version, I need to change back to my Linux package 3.1. But it complete runnable project it 5 minutes. I think I need to spend additional half of hour tomorrow to migrate all my old pet projects too.

Here are steps current .NET Upgrade Assistant Preview ask:

The kind of old good console interaction, thank you, Microsoft!

The Deep Blue Knight

 

Here is a peak of critical thinking in protecting my life in ghettos. Walking through the night to stay against to thug and crackhead to carry the combinatorial magic of programming for a better world.

Fix TURN ON for Google Remote Desktop on Ubuntu 21.04

I use deb packets to setup access and after install sometimes I have no TURN ON button to enable my computer.

There is an answer:

mkdir ~/.config/chrome-remote-desktop

 It looks like some permissions missed to create configuration folder.

Count GitHub stars

I should  prepare my projects carefully to win additional stars. How to count them using starz packet:

C:\Users\epiro>npm install -g starz

C:\Users\epiro\AppData\Roaming\npm\starz -> C:\Users\epiro\AppData\Roaming\npm\node_modules\starz\starz.js

+ starz@0.0.2

added 5 packages from 3 contributors in 2.638s

C:\Users\epiro>starz arise-project -l 5

I can print checklists all the winter wit 18usd Epson.

I bought Epson LQ-100 and two cartridges and in free time I am investigating for does it work. I think cartridges capacity will be enough  to print work checklist all the winter. To spend less ink I moved to print directly with hardware fonts available. To do this on windows:

1. I setup printer from list provided by Microsoft.

 

2. Enable printer pooling from LPT1 to my virtual usb com port. This helped to use command line to direct print through LPT1, it is very fast and cheap.

3. Setup LPT1 in console to my printer.

net use lpt1 "\\localhost\EPSON LQ Series 1 (80)" /persistent:no

4. Print "Hello Word":

echo "Hello Word" > lpt1

Strings similarity according to longest subsequence

 My checklist sometimes  have been changed and when I set some attributes to steps, I need to properly merge new description with existing attributes. But  this is only a text and I want to recognize it is new step in check list or updates to existing. For example

Step1 instruction

Sterp2

I want to change to:

Step1 instruction details

Step2

Then, of course, Sterp1 details is replacement for Sterp1

Metric Longest Common Subsequence from java-string-similarity package helps determine text distance:

MetricLCS lcs = new MetricLCS();
double current = lcs.distance(
        "Step1 instruction",
        "Step1 instruction details");

current: 0.31999999999999995

How it looks integrated in bot core:

Its promising when my checklists  started to archive changes in working process automatically.

Setup Microsoft Bot Framework in Oracle Linux

 Here is a important good news for my ongoing project, I have Bot UI for it directly from Microsoft on my linux. And of course, thank you for this great setup post.

 

Prerequisites are:

sudo yum install libsecret-devel

npm install --save-dev electron-rebuild

sudo yum install openssl

sudo npm install -g yo generator-botbuilder 

Download emulator release

chmod 700 BotFramework-Emulator-4.10.0-linux-x86_64.AppImage  

Create bot:

mkdir myBot

cd myBot

yo botbuilder

cd ypbot/

npm start

Then my bot started:

Run emulator with command:

./BotFramework-Emulator-4.10.0-linux-x86_64.AppImage &

Open bot with url http://localhost:3978/api/messages 

Say hello to your bot

Categories and tags knowledge base for local files

 I had planned to write utility to store documents metadata, stumble upon an kb, a text-oriented minimalist command line knowledge base manager. Let's imagine you have a lot of text and graphics in your system, you need to classify to quick search on it. These documents are known as artifacts, because they all add hyper map to your knowledge then you can obtain it in time, because you know a category or even tag. In my experience, work knowledge base contain thousands of documents and searching with this type of invisible markers make data extraction possible and in many cases incredible fast. So that, how to install KB in Oracle linux:

curl "https://bootstrap.pypa.io/get-pip.py" -o "get-pip.py"
python3 get-pip.py
pip install kb-manager

On ubuntu 20.04

sudo apt install python3-pip

pip3 install kb-manager

Then, kb is located in ~/.local/bin

.NET Core debug, and UML diagrams on linux Visual Code

There is an important to debug .Net Core programs under linux. I thought it's should be different setup for linux OS, but no, thank you for Pluralsight article one sequence for every OS:

1. Add .NET Core Extension Pack.

2. Press Ctrl-Shift-P to open shortcuts to find .NET: Generate Assets for Build and Debug

3. Then use debug pane

I hope debug will help to finish program writing  quicker and then you want to writer documentation using UML diagrams. As for me it is hard to draw UML with vector primitives, it is better to utilize PlantUML

 Extensions to auto generate  uml class diagrams from project code:

1. CSharp to PlantUML - this help to generate all classes in separate .puml files, then you can copy it to your diagram instead of write from scratch

 

2. PlantUML - this extension helps with intelliSense and preview.

You need to install graphviz in your system too.

Its looks like we have ere of Visual Code for linux workspaces for most of languages!

Utils in Graphviz package

 There is a list of utils in graphviz:

acyclic - make directed graph acyclic
bcomps - biconnected components filter for graphs
ccomps - connected components filter for graphs
circo - filter for circular layout of graphs
cluster - find clusters in a graph and augment the graph with this information.
diffimg - Calculates intersection between two images
dijkstra - single-source distance filter
dot - filter for drawing directed graphs
gxl2gv,gv2gxl - GXL-GV converters
dotty - A Customizable Graph Editor
edgepaint - edge coloring to disambiguate crossing edges
fdp - filter for drawing undirected graphs
gc - count graph components
gml2gv,gv2gml - GML-DOT converters
graphml2gv - GRAPHML-DOT converter
gvcolor - flow colors through a ranked digraph
gvgen - generate graphs
gvmap - find clusters and create a geographical map highlighting clusters.
gvpack - merge and pack disjoint graphs
gvpr - graph pattern scanning and processing language
lefty - A Programmable Graphics Editor
lneato - A Customizable Graph Editor
mm2gv - Matrix Market-DOT converters
neato - filter for drawing undirected graphs
nop - pretty-print graph file
osage - filter for drawing clustered graphs
patchwork - filter for drawing clustered graphs as treemaps
prune - Prune directed graphs
sccmap - extract strongly connected components of directed graphs
sfdp - filter for drawing large undirected graphs
tred - transitive reduction filter for directed graphs
twopi - filter for radial layouts of graphs
unflatten - adjust directed graphs to improve layout aspect ratio
vimdot - Combined text editor and dot viewer 

I retrieved it with yum util repoquery:

yum -y install yum-utils
repoquery --list graphviz

Of course, I started with dot for me, but pretty look for all available capabilities in grapviz too.

Simple scenario is a image from dot file:

digraph {
    a -> b;
    b -> c;
    c -> d;
    d -> a;
}

I took this graph from examples. It is easy to generate such graph in C# code today. Then I want to convert it to image, I found this  command:

dot ./1.dot -Tpng > ./1.png

Grayscale view for Gnome in Oracle linux

 I think, a lot of us want to concentrate on their pc work and especially for me colors are distraction. It is easy do disable color filters on Windows, but it is also possible to disable it and make display graysacle in linux too. There are commands to add 'Desaturate all' to gnome shell.

yum install gnome-tweak-tool

git clone https://gitlab.com/JanMa/desaturate_all.git

mv ~/Downloads/desaturate_all "/home/eugene/.local/share/gnome-shell/extensions"

Alt + F2 then r to restart DE

Enable Desaturate all extension in Tweaks app.

Use small 'three circles' icon on the right top corner to enable grayscale.

What I stadied with one year O’Reilly Learning

 It is clear for me, all publishers take their tiers in education process. And O’Reilly is not a beginner in understanding of computer science subject. So that, I can recommend to use publishers as the stairs for unknown technologies or theory and final stair is  O’Reilly. In a year I read 20 books, participate in 2 online training and the learning path. The most important thing for me was to realize that there are people who think like me and these people are experts. I can learn logic and pragmatism from them.

This is my recap from Learning Path: Graph Algorithms, By Mark Needham

1. Using a special framework, such as spark, allows you to focus on selecting a method to solve the problem and quickly determine the correctness of the idea, instead of guessing the only correct approach.

2. The importance of linked data is difficult to override, because the collected relationships allow further use of very simple decision-making algorithms. This means that relationships are a step towards simplifying decisions.

3. Determined algorithms are characteristic of generalization, and they cannot always find solutions for small groups in a variety of settings, but they allow you to see the big picture. Probabilistic solutions can improve the overall picture.

4. The graphs above the graphs and the super category are the key to determine the initial solution path, and these structures can be distinguished from the data.

5. It is the iterative approach in determining the desired algorithm, rather than a single selected approach, that allows you to achieve a solution that will reliably solve the problem, thus experimenting and making conclusions, this is the key to creating reliable solutions, instead of a completely theoretical approach.

Thank you, O’Reilly Learning for this year with me.
