Three days ago, I created a resume. From the description, it is clear that there is not much real work experience, just some knowledge of Angular. No specifics. Nothing substantial. I created the resume and forgot about it… Number of views in the last 3 days: A new HR calls every 2 hours. They write in messengers. Conclusions IMHO Few people like to work on the front-end. Few are willing to work for 120k. […]

The goal of this post: to showcase debugging techniques in Debian/Ubuntu related to "finding the source" in the system configuration file. Test example: after long struggles with a tar.gz copy of the installed OS and after restoring it and installing updates, we receive the message: update-initramfs: Generating /boot/initrd.img-4.15.0-54-generic W: initramfs-tools configuration sets RESUME=/dev/mapper/U1563304817I0-swap W: but no matching swap device is available. I: The initramfs […]
Part 1. About CPU Part 2. About Memory Today, we will discuss the metrics of the disk subsystem in vSphere. Storage issues are the most common cause of slow virtual machine performance. While troubleshooting CPU and RAM issues usually ends at the hypervisor level, if there are disk problems, one may need to investigate the data transfer network and the storage system. I will cover this topic […]

Most attentive users have noticed a half-second appearance of 'vk.com/away.php' in the browser's address bar, but of course, they did not attach any significance to it. Background Once, a certain programmer finalized […]
Six vulnerabilities have been addressed in FreeBSD that allow for privilege escalation in the system or access to kernel data. The issues have been fixed in updates 12.0-RELEASE-p8, 11.2-RELEASE-p12, and 11.3-RELEASE-p1. CVE-2019-5606 is a flaw in the close call handler for file descriptors created through the posix_openpt system call, which may lead to writing to already freed areas of kernel memory (write-after-free). A local attacker may […]
I want to share my experience with the evolution of database systems usage in the GLASHA online language school. The school was founded in 2012, and at the beginning of its operations, it had only 12 students, so there were no problems with scheduling and payments. However, as it grew, developed, and new students appeared, the question of choosing a database system became pressing […]
