Regex101 is an online regular expression editor and debugger. You can test your regular expressions against sample data, see if the expression worked, watch it matched, and so on. Having an explanation for each part of the regular expression dynamically generated, and a quick reference nearby is super handy too.
Update (November 7, 2018): Here’s another Regex Tester.
PHP Smart Analyzer (or PHPSA for short) is yet another item in a growing list of tools for PHP code static analysis. It’s in an early alpha state, but looking at the list of goals, it’s quite promising.
If that’s up your valley, have a look also at PHPQA and PHPStan, which I wrote about earlier.
Here are some exciting news from the BitBucket Pipelines blog: Bitbucket Pipelines now supports building Docker images, and service containers for database testing.
We developed Pipelines to enable teams to test and deploy software faster, using Docker containers to manage their build environment. Now we’re adding advanced Docker support – building Docker images, and Service containers for database testing.
Johannes Weber, a networking and security professional, has done something really cool while preparing for his CCNP SWITCH exam. He has built a lab with some networking equipment, configured it all, and captured network traffic, featuring a variety of level 2 and 3 protocols. He has published his setup, the captured traffic, and a variety of challenges, that helped him to prepare, and which can help others.
While preparing for my CCNP SWITCH exam I built a laboratory with 4 switches, 3 routers and 2 workstations in order to test almost all layer 2/3 protocols that are related to network management traffic. And because “PCAP or it didn’t happen” I captured 22 of these protocols to further investigate them with Wireshark. Oh oh, I remember the good old times where I merely used unmanaged layer 2 switches. 😉
In this blogpost I am publishing the captured pcap file with all of these 22 protocols. I am further listing 45 CHALLENGES as an exercise for the reader. Feel free to download the pcap and to test your protocol skills with Wireshark! Use the comment section below for posting your answers.
Of course I am running my lab fully dual-stacked, i.e., with IPv6 and legacy IP.
I think these are great for several reasons:
The lab setup includes the following:
- 1x Cisco Catalyst 2960, (C2960-LANBASEK9-M), Version 15.0(2)SE9
- 2x Cisco Catalyst 2950, (C2950-I6K2L2Q4-M), Version 12.1(22)EA14
- 1x Cisco Catalast 3560, (C3560-IPSERVICESK9-M), Version 12.2(55)SE10
- 3x Cisco Router 2811, (C2800NM-ADVENTERPRISEK9-M), Version 15.1(4)M9
- 2x old Notebooks, Dell or somewhat, running either Ubuntu or Knoppix Linux
Personally, I am not very involved with networks these days. But even for more me the above setup serves as a reminder of how complex underlying technology infrastructure has got in recent years – hardware, software, protocols, and all.
phpunit-snapshot-assertions – is an interesting addition to the PHPUnit assertions which allows testing against previously created snapshots. This is particularly useful for testing the outputs of API end-points, format conversion functions, and the like. Instead of testing the actual functionality, these assertions allow to compare the output of the current test run with the known good output of a previously created snapshot.
This works well for generic text, but even better for widely used formats like JSON and XML, where, in case of a failed assertion, a meaningful difference can be provided.
Here is a blog post providing some more details on philosophy and methodology.
