  What's really cool is that users are tracking ahead of growth. Which indicates that people are finding the community, using it, and the growth is being driven healthily by a direct correlation to increased people - e.g. it's not coming from bots or automation, and not from huge changes in behaviour but from the site simply growing across the board.

  @Dashrender said in Why are Windows Management GUI Elements So Tiny?: @scottalanmiller said in [Why are Windows Management GUI Elements So Tiny?] I'm sure it rarely if ever actually starts there. As already said - it was legacy, and never updated. They are finally getting around to updating most of the control panel applets - but we're still frequently stuck dealing with the old style for things like the java security admin, etc. No one claimed it started there. That it might have started with incompetence is fine, that it isn't seen as a priority to fix something so simple, but so universally important, is where they get some actual financial benefit in making GUI users pay a higher price to encourage people to see the CLI agenda as more important than it would be if the GUI was done better.

  Software Management The YUM package manager is now based on the DNF technology and it provides support for modular content, increased performance, and a well-designed stable API for integration with tooling. Web servers, databases, dynamic languages Python 3.6 is the default Python implementation in RHEL 8; limited support for Python 2.7 is provided. No version of Python is installed by default. RHEL 8 provides the following database servers: MariaDB 10.3, MySQL 8.0, PostgreSQL 10, PostgreSQL 9.6, and Redis 4.0. Desktop GNOME Shell has been rebased to version 3.28. The Gnome Display Manager uses Wayland as the default display server. The X.Org server, which is the default display server in RHEL 7, is available as well. Installer and image creation The Anaconda installer can utilize LUKS2 disk encryption, and install the system on NVDIMM devices. The new Composer tool enables users to create customized system images in a variety of formats, including images prepared for deployment on clouds of various providers. Composer is available as a Technology Preview. Installation from a DVD using Hardware Management Console (HMC) and Support Element (SE) on IBM Z. File systems and storage The Stratis local storage manager has been introduced. Stratis enables you to easily perform complex storage tasks and manage your storage stack using a unified interface. The LUKS version 2 (LUKS2) format replaces the legacy LUKS (LUKS1) format. The dm-crypt subsystem and the cryptsetup tool now uses LUKS2 as the default format for encrypted volumes. Security System-wide cryptographic policies, which configures the core cryptographic subsystems, covering the TLS, IPSec, SSH, DNSSec, and Kerberos protocols, are applied by default. With the new update-crypto-policies command, the administrator can easily switch between modes: default, legacy, future, and fips. Support for smart cards and Hardware Security Modules (HSM) with PKCS #11 is now consistent across the system. Networking The nftables framework replaces iptables in the role of the default network packet filtering facility. The firewalld daemon now uses nftables as its default backend. Support for IPVLAN virtual network drivers that enable the network connectivity for multiple containers. Virtualization A more modern PCI Express-based machine type (Q35) is now supported and automatically configured in virtual machines created in RHEL 8. This provides a variety of improvements in features and compatibility of virtual devices. Virtual machines can now be created and managed using the Cockpit web interface. The QEMU emulator introduces the sandboxing feature, which provides configurable limitations to what systems calls QEMU can perform, and thus makes virtual machines more secure. Compilers and development tools The GCC compiler based on version 8.2 brings support for more recent C++ language standard versions, better optimizations, new code hardening techniques, improved warnings, and new hardware features. Support for the DWARF5 debugging information format across various tools for code generation, manipulation, and debugging. Kernel support for eBPF tracing, used in the SystemTap tool. The glibc library based on version 2.28 adds support for Unicode 11.0.0, several improvements in the DNS stub resolver, as well as higher performance. High availability and clusters The Pacemaker cluster resource manager has been upgraded to upstream version 2.0.0, which provides a number of bug fixes and enhancements. In RHEL 8, the pcs configuration system fully supports Corosync 3, knet, and node names.

  @dyasny said in Why Do Recruiters Never Get Involved in Forums Like This: @scottalanmiller said in Why Do Recruiters Never Get Involved in Forums Like This: Most recruiters sending me things don't even state where the job is. It's a weird thing I've found, like they think that there is only one market in the whole world and that I'll just know where they must mean. My first question is always "what country is this for"? Strange, I typically see them specifying the city or whether or not the job is remote from the very start. There was a bit of initial confusion when I moved countries several times, but it straightens out quite quickly Definitely many do specify, but an absurd number do not.

  @StorageNinja said in MongoDB Major Change to Licensing: @scottalanmiller said in MongoDB Major Change to Licensing: if you are a SaaS vendor looking at building software that uses MongoDB somewhere, you'd better get a lawyer looking over this license and how it applies to you. This is becoming a bigger issue as the biggest SaaS vendors hide behind this clause more and more with incredibly proprietary forks. They offer very little to no actual core development or contribution and it goes against the previous method of GPL code getting funding. It annoys me, as the legal headaches of contributing internal only use code back will block some companies from using OSS, but I see it both ways. The startups who are doing a lot of the core housekeeping of NOSQL platforms are learning they can't find a business model. This is getting messier and messier. Partially because there are just too any vendors involved. What's amazing, though, is that a move like this took a customer who was very into MongoDB and using it in projects and was literally working with MongoDB's own hosted product and now looking to avoid it like the plague. So at least in this one case, they are likely losing hosted product from this. And gaining nothing. I imagine a lot of customers going through this same process.

  @StorageNinja said in I am going to start an ISP: @NerdyDad said in I am going to start an ISP: @Reid-Cooper Tell that to rural America that is still on less than 1 Mbps speed DSL while cities like New York, Dallas, and LA are pushing towards 1 Gbps. Given, it is the peoples choice to live in rural America, but the phone companies also have no interest in upgrading their infrastructure because the ROI is crap. People who can't live without 50Mbps do not live live in non-rural area's. In theory, a WISP might open up housing markets for people like me who work remotely but the other inconveniences of rural life (no 1-2 hour delivery for groceries/Amazon, poor restaurant choice, crazy bad schools, long distance to airports, poor job opportunities for my spouse) stack the deck that the Total Addressable market is going to grow much except for area's JUST outside the city that a telco will eventually expand as they get denser. You have to hope for a large enough TAM to break even, but NOT too BIG of one that Comcast comes in and fucks up your monopoly. Welcome to being an ISP where your break-even can't get too good before someone ruins it. Also, your access to capital for refresh can dry up at any moment, regulations could 10x your operational costs. And people who need the speed, but also want to be rural, have often already moved to countries where doing so is even cheaper. This is one spot where the US really struggles. So many countries offer great Internet, and dirt cheap rural living, that allows for working from home while being completely remote.

  @scottalanmiller said in StarWind Success Story: Innotech Windows + Doors reduces IT costs by 80%: This kind of savings should always be stated as "in comparison to." So like solution X is a 50% savings versus solution Y. Because there is always a free option, which often involves doing nothing. "Savings" is a weird concept in general. Sounds good in a commercial, but rarely means anything. That marketing is so ingrained in people anymore.

It made me think of the Sha Na Na cover of the Little Anthony and the Imperials song Tears on my Pillow and now that is stuck in my head instead. This version sucks but it's the best I could find that's closest to what I'm talking about: Youtube Video

  @scottalanmiller said in Battery Backup with SSD raid: @pete-s said in Battery Backup with SSD raid: @scottalanmiller said in Battery Backup with SSD raid: @pete-s said in Battery Backup with SSD raid: @scottalanmiller said in Battery Backup with SSD raid: SSD NV protection is to allow the SSD's cache to flush safely should power be lost. RAID NV / battery protection is to allow the RAID's cache to flush safely should power be lost. Each is important on its own, neither covers for the other one. That's technically slightly incorrect. The non-volatile cache memory on the raid controller is to be preserve the data that has not yet been written to the drives, until power is restored again. On the SSD the capacitors hold enough charge so that the drive can write the remaining data in the cache memory to the actual flash memory after the power is gone. The cache is DRAM so it will loose it's contents after a few seconds. The only time details like this matter is if you remove the battery from a raid card, your data might be lost. I'm missing how that is different than what I said. What you said is correct, but I feel like you just reworded what I said, with the added detail that the RAID card flush is not until power is restored, which one hopes is obvious. Sorry Scott, you're right. I was just thrown off by you said "SSD NV protection" and because you worded both thing the same. Obviously both things are to protect from data loss at power failures. OIC, you are saying that the SSD is volatile, but has a battery in most cases? makes sense. Almost, let me explain. Below is a picture of an Samsung enterprise SSD, SM863. The SSD controller (yellow) is the brain. The flash memory (green cross) is non-volatile so it will not suffer data loss without power. There are also more flash memory on the backside. The cache memory however is the blue ring and it will lose it's memory as soon as the power is removed. It's the same type as the memory in your computer, DRAM. That would cause immediate data loss and that is not good and that is why enterprise drives have a lot of capacitors (red circles). The capacitors (red) act like small rechargeable batteries. When the drive loses it's external power these small capacitors will work as a reserve power for the entire drive. The controller (yellow) knows that it has lost external power so it will quickly write the data from the cache memory (blue) to the flash memory (green) before the reserve power from the capacitors (red) are empty. That way data loss is prevented. This will only take a couple of seconds at most.

  @gilberto said in raid partition 0: Excuse my ignorance. Now I was installing x2go. If I partition the hdd in raid 0 I also need to rebuild the operating system or just x2go. thank you. To reiterate: Any time you are reconfiguring an array, you lose everything on the array. If you want to keep the data, you must back the data up to a separate medium and restore it once you are done configuring the array.
