Friday evening often turns out to be an evening of memories, and not only about the past week, but about much earlier events. This Friday, I remembered one interesting program for MS DOS (as well as for Mac OS, UNIX and VAX /VMS) - Pascal interpreter and IDE Dr. Pascal. Detailed information about the features and reviews can be found on the archive manufacturer site Visible Software (USA), and I will confine myself to the most memorable ideas for me, and these ideas, in my opinion, even today have not lost their relevance. First of all, remember the picture:

3r3-31. On October 1? 201? our team released a new version of the React Native application. We are pleased and proud of it.
 
 
But what a horror: after a few hours, the number of crashes under Android suddenly increases.
 
 
 

1?000 crashes under Android

Our crash monitoring tool Sentry going crazy.

I mentioned the program on Habré several times. Check Point Security Academy : its essence is that the company Check Point in the summer, announced a competition in the Capture the Flag format, where the participant’s past experience is not important, but only his ability to unravel cyber puzzles is important. According to the results of this competition, the company recruited twenty participants for a three-month professional course on cyber security, and all participants from the very beginning of the course receive a full salary of a specialist in KB, under the obligation to work ...

From the translator: 3r3133. George Alan Heimel in his article 3-3r39. divided
own experience and talks about what should guide the developer in the debugging process.
 
 
Modern developer tools are quite extensive, so there are plenty to choose from - debugging tools. Many of them are automated, but, unfortunately, debugging will not work out of course - there is still a lot of manual work. Sometimes it seems that the problem simply should not be, it is impossible, everything should work. But does not work. In order not to waste extra nerve cells and time, I derived simple rules for debugging...

process. <{full}>
There is an opinion that the development takes about 10% of the time, and debugging - 90%. Perhaps this statement is exaggerated, but any developer agrees that debugging is an extremely resource-intensive process, especially in large multithreaded systems.
 
 
Thus, optimization and systematization of the debugging process can bring significant benefits in the form of saved man-hours, increasing the speed of problem solving and, in the end, increasing the loyalty of your users.

Kind time of the day, Habr!
 
 
A year ago my process of debugging code in PHP consisted of two lines:
 
var_dump ($ variable);
die ();
 
Periodically, of course, we had to use more "complex" designs:
 
console.log (data);

 
echo json_encode ($ variable, JSON_UNESCAPED_UNICODE);
exit ();
 
No, you! I knew - in our time it does not fit for a cultural programmer to deal with this
ancient craft [/b]
joke about another ancient craft
 
 
But, frankly, I was always afraid of what I do not understand. Including printers xDebug, in particular, how to set up this whole thing. One day ...

Recently, when writing a library to ESP-3? it became necessary to catch the deadlock, which sometimes arose because of my curvature, which led to the purchase of a debugger card with the JTAG interface. What came of it - read under the cut.
I ordered it on 3ee3r3344. for ??? rubles. together with the delivery of ePacket. The fee comes with unburned feet, which is only to our advantage, since we do not need them.
 
A set of wires, 6 pieces: one end to solder, the other - to ESP-32.
 
I highly recommend the USB extension cable, without it it will be tight

UFW (Uncomplicated Firewall) is an iptables interface designed to simplify the process of configuring the firewall. The iptables tool is reliable and flexible, but it will not be easy for a novice to configure it yourself. I'm just new to this business.
 
 
By default, iptables includes the ACCEPT policy and looks like this:
 
 
 
 
In our example, there are no restrictions. The default policy is ACCEPT.
 
 
INPUT - INCOMING CONNECTIONS.
 
OUTPUT - OUTPUT CONNECTIONS.
 
FORWARD - ROUTING (FOR EXAMPLE, YOU NEED TO PRINT THE ROUTE to the computer behind the gateway).
 
 
You can enable ufw with the command ...

 
 
Functional tests are a useful thing. At first they do not take much time, but the project is growing, and more and more tests are needed. We did not intend to endure the slowdown in the speed of delivery and, gathering strength, accelerated the functional tests three-fold. In the article you will find universal advice, however, you will notice a special effect on large projects.

It's a trick that I learned about recently from the Android Android Developer in my company, and now I feel unhappy, regretting the time I spent waiting for the Gradle build to check my changes when writing Android applications.
 
Here is a typical scenario that every Android developer could meet at least once during its development life cycle. You have a list of the items you want to show in
ListView
or
RecyclerView

Below is our beloved method onBindViewHolder , which connects your model to your view-components RecyclerView .
