Reversing and hacking external self-encrypting drives has been a long-time hobby of mine. In the past, I've worked with models like Zalman VE-400, Zalman ZM-SHE500, and Zalman ZM-VE500. Recently, a colleague brought me another specimen: Patriot (Aigo) SK8671, which features a typical design â an LCD indicator and a keypad for PIN entry. Here's what I came up with⊠1. Introduction […]
We previously wrote about how easily and simply the Zimbra Collaboration Suite Open-Source Edition can be scaled. New mail storages can be added without shutting down the infrastructure running Zimbra. This capability is highly valued by SaaS providers who offer access to the Zimbra Collaboration Suite on a commercial basis. However, this scaling process is not without […]
How to read this article: I apologize for the lengthy and chaotic text. To save your time, I start each chapter with an introduction titled "What I learned," where I outline the essence of the chapter in one or two sentences. "Just show me the solution!" If you only want to see what I have come to, skip to the chapter "Becoming more inventive," but […]
Hello, readers of Habr! The topic of this article will be the implementation of disaster recovery measures in AERODISK Engine storage systems. Initially, we intended to write about both methods in one article: replication and metrocluster, but unfortunately, the article became too large, so we split it into two parts. Letâs start with the basics. In this article, we will set up and test synchronous […]
Service Mesh is a well-known architectural pattern for integrating microservices and transitioning to cloud infrastructure. Today, it's quite difficult to manage without it in the cloud-container world. Several open-source implementations of service mesh are already available on the market, but their functionality, reliability, and security are often insufficient, especially when it comes to the requirements of large national financial companies. Therefore […]
hashget â tasuta, avatud lĂ€htekoodiga deduplikatsioonitööriist, mis on sarnane arhiiveriistaga ja vĂ”imaldab olulisel mÀÀral vĂ€hendada varukoopiate suurust ning korraldada inkrementaalsete ja diferentsiaalsete varukoopia skeeme ning mitte ainult. See on ĂŒlevaade, mis kirjeldab vĂ”imalusi. Hashget'i kasutamine (suhteliselt lihtne) on selgitatud projekti README-s ja wiki-dokumentatsioonis. VĂ”rdlemise osas, nagu ĆŸanr nĂ”uab, alustan kohe intrigeerivast vĂ”rdlusest […]
Umbes nii. See on osa ventilaatoritest, mis osutusid ĂŒleliigseks ja demonteeriti kahekĂŒmnest serverist testseisakus, mis asub DataPro andmekeskuses. Allpool â liiklus. Illustreeritud kirjeldus meie jahutussĂŒsteemist. Ja ootamatu pakkumine vĂ€ga sÀÀstlikele, kuid veidi kartmatutele serverite omanikele. Serverite jahutussĂŒsteemi, mis pĂ”hineb kontuursetel soojusputkedel, peetakse alternatiiviks vedelikjahutusele […]
KĂ€es on 2019. aasta ja me peame langetama otsuse seoses GIF-idega (ei, jutt ei ole sellest otsusest! Siin me kunagi ei lepi kokku! â jutt on ingliskeelsest hÀÀldusest, meie jaoks ei ole see oluline â toimetaja mĂ€rkus). GIF-id vĂ”tavad tohutult ruumi (tavaliselt mitu megabaiti!), mis, kui sa oled veebiarendaja, on tĂ€ielikus vastuolus sinu soovidega! Kuidas […]
Eelmises artiklis kirjeldasin toodete importimise protsessi Magento 2's tavalise meetodi kaudu - mudelite ja hoidlate kaudu. Tavaline meetod erineb vĂ€ga madala andmetöötluse kiirusest. Minu sĂŒlearvutis tuli umbes ĂŒks toode sekundis. KĂ€esolevas jĂ€tkusu artiklis kĂ€sitlen alternatiivset toodete importimise meetodit - otse kirjutamist andmebaasi, mööda Magento 2 standardmehhanisme […]
LinnatĂ€navatel seisvad raudkastid rahaga ei saa jĂ€tta tĂ€helepanuta kiiret kasumit jahtivaid inimesi. Kui varem kasutati ATMide tĂŒhjendamiseks puhtfĂŒĂŒsilisi meetodeid, siis now on mĂ€ngu astunud ĂŒha keerukamad arvutipettused. Praegu on kĂ”ige olulisem neist - âmust kastâ, milles on ĂŒhenplaadine mikroarvuti. Kuidas see […]
Magento on e-kaubanduse lahendus, st rohkem keskendunud toodete mĂŒĂŒmisele kui mĂŒĂŒgiga seotud laoseisu, logistikate ja finantseerimise haldamisele. MĂŒĂŒgiga seotud paremaks haldamiseks sobivad teised rakendused (nĂ€iteks ERP-sĂŒsteemid). SeetĂ”ttu tekib Magento kasutamise praktikas sageli vajadus integreerida pood nende teiste sĂŒsteemidega (nĂ€iteks 1C-ga). Ăldiselt vĂ”ib integreerimise kokku vĂ”tta andmete replikatsiooniks: […]
Kaasaegsed andmekeskused nĂ”uavad hoolikat lĂ€henemist elektritoitele. On vajalik samal ajal jĂ€lgida koormuste seisundit ja hallata seadmete ĂŒhendust. Seda saab teha, kasutades kabinette, mooduleid vĂ”i energiajaotuse blokaid. Milline tĂŒĂŒpi energiatootmine sobib konkreetsete olukordade jaoks kĂ”ige paremini, rÀÀgime meie postituses Delta lahenduste nĂ€idete pĂ”hjal. DĂŒstabeene areneva andmekeskuse energiatarnimine osutub tihti keeruliseks ĂŒlesandeks. […]
