Hello, Habr! My name is Maxim Vasiliev, and I work as an analyst and project manager at FINCH. Today, I would like to share how we processed 15 million queries in 6 minutes using ElasticSearch and optimized the daily load on the website of one of our clients. Unfortunately, I have to skip names as we have an NDA, but we hope that […]
Information technology allows us to access incredibly cool educational resources with just one click. For free. I'm currently tackling the challenge of how to sift through a massive amount of vital content to figure out what should be tried first, how to 'mark up the data' so that the neural network of the younger generation learns more effectively. (ontol.org, 'Burnout', 'Remote Work', Telegram channel). I present to you a complete selection of all free courses from […]
I 'scanned' 560 posts on Habr and (preliminarily) highlighted the top 10 most useful materials on emotional/professional burnout for myself. Social architecture: 'Emotional Burnout of Open Source Contributors' Maxim Dorofeyev: 'The Principle of Thought Fuel Economy' Ilya Yakyamsev: 'Efficiency Doesn't Work' Sam Altman: 'Productivity. Experience from the Best Startups of Y Combinator' Aaron Harris(YC): 'Coping with Founder Depression' Jonathan Blow: 'Techniques for Dealing […]
'If you're not ashamed of the first version of your product, you've entered the market too late' Hello everyone, I’ve been dragging my feet for a long time, and now I've decided to share not even an MVP, but the idea I’m currently working on. It crystallized a year ago, following 7 years of writing on Habr. Many have heard of the pyramid 'data-information-knowledge-wisdom.' Interestingly, the number of projects about data […]
The subject of this article is connecting external devices to a Mac via SAS, Fibre Channel (FC), eSATA interfaces. Let's clarify right away that there is a healthy pathway to solve the problem of accessing such devices: assemble a cheap PC, plug a SAS or FC HBA controller card into it (for example, a basic LSI adapter), connect your devices to this controller, and install any […] on the PC.
From the Google Blog Editor: Have you ever wondered how Google Cloud Technical Solutions (TSE) engineers handle your support requests? TSE support engineers are responsible for identifying and resolving user-reported issues. Some of these issues are quite simple, but sometimes a request requires the attention of several engineers at once. In this article, one […]
We are increasingly receiving requests from clients to provide access to the Kubernetes cluster in order to interact with services inside the cluster: to connect directly to a database or service, or to connect a local application with applications inside the cluster… For example, there is a need to connect from one’s local machine to the service memcached.staging.svc.cluster.local. We provide this capability using […]
Previously, we noted that with the introduction of Check Point Maestro, the entry level (in monetary terms) for scalable platforms has significantly decreased. There is no longer a need to purchase chassis solutions. You take exactly as much as you need and add more as necessary without large initial costs (as with chassis solutions). You can see how this is done here. For a long time, orders […]
We won't open America if we claim that virtual machines on new processors are always more efficient than equipment on older generation processors. What's more interesting is that when analyzing systems that seem very similar in technical specifications, the results can be quite different. We confirmed this when we tested Intel processors in our cloud to see which ones provide the greatest […]
In this article, we will look at a number of optional yet useful settings: using additional names for the manager; connecting authentication via Active Directory; Multipathing; power management; replacing SSL certificates; archiving; host management interface (cockpit); VLANs; HPE-specific features. This article is a continuation, see oVirt in 2 hours Part 1 and part 2. Articles Introduction Installing the manager (ovirt-engine) and […]
Introduction The open source project oVirt is a free enterprise-level virtualization platform. Skimming through Habr, I found that oVirt is not covered here as widely as it deserves. oVirt is actually the upstream for the commercial system Red Hat Virtualization (RHV, previously RHEV), growing under the wing of Red Hat. To avoid confusion, this is not the same as CentOS vs RHEL, the model […]
This article is the next in the oVirt series, starting here. Articles Introduction Installing the manager (ovirt-engine) and hypervisors (hosts) — We are here Additional settings Now, let's look at the issues of the primary installation of the ovirt-engine and ovirt-host components. For more details, the installation processes can always be viewed in the documentation. Content Installing ovirt-engine Installing ovirt-host Adding a node to oVirtN Configuring the network interface Configuring FC […]
