I work in technology sector. And I do round a clock, not only from 9 to 5. It is my bread and butter, it is my hobby, it is the fascination of my life. And with the current rate of change particular in information technology (IT), there is always something new to learn, to try, to talk about. I often post news, thoughts, and reviews. And when I do, this is the category I use.
BitBucket is celebrating an important milestone – 10 million registered users. With 28 million repositories and 3.5 million build minutes every week, BitBucket is a vital tool for many teams.
I am (and have been) a member of several teams and projects, which heavily rely on BitBucket (and BitBucket pipelines) for their day-to-day operation.
Happy 10 million milestone, BitBucket! Keep it the great work!
Currently, there are 3796 devices monitored by the Zabbix server, which in turn houses the MySQL database and the web front-end. This server is operated virtually with 8 CPUās and 32GB RAM supported by SAS storage system. 105818 items are queried by the Zabbix server from those devices, where 23820 triggers detect whether certain items deviate from their target state. This results in 298.48 NVPS with an average of approx. 7 people (actively) using the system concurrently. General overview: * Each device inside a tram/subway is treated as a host and is monitored for availability. * Each tram/subway is managed as a host group. * Host groups are nested and organized by the tram/subway lines (using the host group nesting feature introduced in Zabbix 3.2). * All devices depend on the connectivity of the MRCU (Mobile Radio Control Unit in subways) or LTE router (LTE G4 Connectivity in trams) * Maps are automatically created for each tram/subway (using the Zabbix API). * Maps use sub-maps to link to a specific tram/subway view.
There’s also a video from the Zabbix conference, presenting the case study.
This year’s results for StackOverflow Developer Survey are in. This is probably the largest survey of IT professionals, with nearly 90,000 participating this year.
As always, there are plenty of insightful findings and correlations in the results. But one that I was somewhat glad to see was the attitude towards Blockchain technology.
While the mainstream media continues to confuse Blockchain with cryptocurrencies, technical people do understand the difference. And the majority (29.2% + 26.2% = 55.4%) of the survey respondents think it is useful for a variety of things outside of the cryptocurrency.
And with all the hype around cryptocurrencies and Blockchain, the majority of the organizations are not working with the technology just yet. Furthermore, of those that do work with Blockchain, the majority is NOT using it for the cryptocurrency.
That is pretty close to my mental picture of what’s going on.
Recently, I had an issue with one of the servers, where a bunch of services were attaching to IPv6 ports instead of the IPv4 ones. Rather than editing the configuration of each of these services, I wanted to simply disabled IPv6 on the machine.
In the old good days, things like these were easily done via the sysctl. I surely tried that option too, but it wasn’t enough. Turns out, the proper way these days is to do this via Grub, as per this blog post:
Here are a couple of handy Google Chrome extensions that I came across the other day.
PHP Console
PHP Console can display PHP errors and var dumps in the Google Chrome Developer Console and notification popups. It can also execute PHP code remotely, with the help of this server side library.
JavaScript Errors Notifier
JavaScript Errors Notifier lets you know of any JavaScript errors either with an icon highlight, or with a popup window. This makes things a lot easier to notice.
