The National Institute of Standards and Technology (NIST), founded in 1901, is now part of the U.S. Department of Commerce. NIST develops industry-wide frameworks and guidelines, including a range of cybersecurity recommendations and resources. It advises against the use of knowledge-based authentication methods, such as personal questions, due to their susceptibility to being easily guessed. Instead, NIST recommends three simple principles for securing passwords, PINs, and passphrases: they should be long, complex, and random.
- Long -- 15 characters minimum
- Complex -- hard for computers to guess, easy for humans to remember
- Random -- if a human can create it a computer can guess it.
Ethernet switches aren’t exactly made for audio. And yet, they are the backbone of the IP audio networked facility. They have the power to make or break, literally, your broadcast operation. Here are a few things we’ve learned over the years in working with switches.
IP audio networks for broadcast are built on multicast, WheatNet IP audio included. Ethernet switches do not natively manage multicast traffic. They send multicast packets to every port on the switch, whether the devices connected to those ports requested streams or not. When more traffic arrives at the port than the device can handle, flooding occurs and that results in audio dropouts or complete loss of audio.
For this and other reasons, managed switches are best for broadcast. These Ethernet switches have control, security, and monitoring features that unmanaged switches lack. Among the most important are two key IGMP (Internet Group Management Protocol) features for managing audio packets: IGMP Snooping and an IGMP Querier.

The Russian Transport Ministry is blaming the Ukrainian military for the massive explosion that sent the 93,000-ton liquid natural gas tanker Arctic Metagaz to the bottom of the Mediterranean. The Arctic Metagaz, a sanctioned Russian-flagged LNG tanker, was en route from Tieshan, China, to Port Said, Egypt with a cargo of 61,000 tons of LNG. When she was about 150 miles off Sirte, Libya, she lit up the Mediterranean sky.
This calculator is used to size pumps. The calculator determines the total differential head of the pump and the absorbed power required. Frictional and static pressure drops in the suction and discharge lines are also calculated as well as the NPSH available.
Clone the item back to your individual vault by using the Options menu to select Clone. This can be done from the Admin Console or, if you are an Owner, Admin, or have Manage collection access to the collection the item is kept in, it can also be done from your Vaults view.
Delete the item from the organization vault by selecting Delete from the Options menu.
For Raspberry Pi clusters, ham radio
digital modes, logging infrastructure, or anything where precise
timestamping matters, it’s noise.
A Stratum 1 NTP server solves this permanently: GPS satellites carry atomic-clock-derived time. A GPS receiver with a pulse-per-second (PPS) signal gives you sub-microsecond accuracy. Your entire network syncs directly from that, with no upstream dependency, no internet requirement, no pool latency.
Here’s how to build one for under $20.
This guide covers the Bitwarden approach to onboarding and succession planning for members of your organization, starting with our approach to the relationship between members and organizations, then covering the simplest use-cases for onboarding and succession, and finally and moving on to the levers and options at your disposal to fit Bitwarden to your needs.
The "out of memory" pop-up says your'e running out of the limit on private committed memory—a type of virtual memory. Not that you're running out of RAM (physical memory). It doesn't matter how much available RAM you have. Having lots of Available RAM does not allow you to exceed the commit limit. The commit limit is the sum of your total RAM (whether in use or not!) plus your current pagefile size.
Conversely, what "uses up" commit limit (which is mostly the creation of process-private virtual address space) does not necessarily use any RAM! But the OS won't allow its creation unless it knows there is some place to store it if it ever needs to. So you can run into the commit limit without using all of your RAM, or even most of your RAM.
If you want to find out what's using committed memory you need to look at Task Manager's "Details" tab and enable the "Commit size" column.
Nor will the total of the "Commit size" columns add up to the "commit charge" (30.1 GB on your machine), because other things contribute to commit charge: Nonpaged and paged pool and some more "subtle" mechanisms like copy-on-write sections, pagefile-backed sections, AWE mappings... but these are usually small compared to process-private v.a.s.)
On that tab, the "Memory (Private working set)" column corresponds to what the "Processes" tab shows for "Memory". This is the RAM currently assigned to each process for its committed virtual address space. The remainder will be in the pagefile. But, again, processes have other types of address space, mostly of the sort called "mapped", and some fraction of that will be in RAM as well. There are other system-wide things created by the OS, not specific to any process, that use up RAM too.
The Google Authenticator app can generate one-time verification codes for sites and apps that support Authenticator app 2-Step Verification.
If you set up 2-Step Verification, you can use the Google Authenticator app to generate codes to sign in to your Google Account. You can still generate codes without an internet connection or mobile service.
Microsoft Authenticator is a mobile app that helps you sign in to all your accounts without using a password.
Notes:
Microsoft Authenticator is not available for PC or Mac as authenticator apps are typically designed for smartphones for security reasons. Learn more.
Microsoft no longer supports Authenticator versions that are more than one year old. Always keep your device up to date.
Bitwarden Authenticator is a standalone app that generates time-based one-time passwords (TOTPs) for logins that support authenticator app two-factor authentication (2FA). It generates 5-10 digit codes, by default using SHA-1 and rotating them every 30 seconds.

The original Allied powers united because of a web of bilateral treaties activated in the wake of Austrian Archduke Franz Ferdinand’s assassination by a Serbian nationalist on June 28, 1914. In a domino-like chain reaction, Austria-Hungary declared war on Serbia (July 28); Serbia’s protector, Russia, mobilized its forces to defend Serbia (July 30); and Austria-Hungary’s ally, Germany, declared war against Russia (August 1), which also necessitated declaring war against France (August 3). Germany’s plan for fighting France required it to first invade Belgium (August 3–4). Great Britain was obligated to defend Belgium, so it responded by declaring war against Germany (August 4). And as an ally of Great Britain, Japan declared war against Germany on August 23.
It works with all browsers and is not limited to just browser use. Use it to log into any device, application, or unlock encrypted drives.
Some sites support OTP codes; others support security keys. OnlyKey does it all and is the most universally supported 2FA key.
You can use your OnlyKey immediately for two-factor authentication and passwordless login (FIDO2) supported by major websites such as Microsoft, Google, Facebook,Dropbox, GitHub,Okta, AWS and more.
Keep your online accounts safe from hackers with the Security Key by Yubico. Trustworthy and easy-to-use, it's your key to a safer digital world.
Convenient and portable: The Security Key NFC fits easily on your keychain, making it convenient to carry and use wherever you go, ensuring secure access to your accounts at all times. Simply plug in via USB-A or tap on your NFC-enabled device to authenticate.
With the Nitrokey Passkey, you can reliably protect your accounts against phishing and password theft. The device allows super simple and secure passwordless login as well as two-factor authentication (2FA) using the modern WebAuthn or FIDO2 standard. This standard is supported by more and more websites and aims to replace traditional passwords. The device has a practical USB-A mini format and therefore fits on any key ring.
Store and sync passkeys in Bitwarden
