![]() The IETF studies operational and technical problems with the Internet, specifies protocols and architectural solutions, and makes recommendations to its steering committee, the Internet Engineering Steering Group ( IESG). The first IETF meeting held in Europe was in Amsterdam in July, 1993. The fourteenth meeting was hosted by Stanford University in July, 1989, and led the Internet Architecture Board to consolidate many task forces into the IETF and the IRTF. The seventh meeting was hosted by the MITRE corporation in McLean, Virginia, in July, 1987, and had more than 100 attendees. ![]() The first IETF meeting was held in January, 1986 in San Diego, and had 15 attendees. ![]() For example, their voting members are selected according to a random process to guarentee unbaised selections, as described in Publicly Verifiable Nominations Committee (NomCom) Random Selection, RFC 3797. The culture of the IETF has always been open and informal, an influence taken from its predecessor, the Network Working Group. It consists of Internet administrators, designers, vendors, researchers, and individuals interested in the evolution of the Internet architecture, and is responsible for improvement of the Internet technology protocols and standards. The Internet Engineering Task Force (IETF) was created in 1986 by the Internet Architecture Board. The Internet Engineering Task Force (IETF) is an open global community of network designers, operators, vendors, and researchers producing technical specifications for the evolution of the Internet architecture and the smooth operation of the Internet.

To use Ventoy, you need a USB drive (be it a USB stick, an external hard drive, a memory card, etc.) that is large enough to hold the ISO images you are going to use. For future reference, to write this text I use this version. The latest release (1.0.17) is just 4 days old, from July 25th. The first release of Ventoy (1.0.0) was made available on April 5th. Ventoy was very useful for me last week, when I installed Windows and Linux on my new SSD Kingston A400, which I received from warranty after the previous one suffered from the SATAFIRM S11 bug. I have been using it to test Linux Kamarada 15.2 Beta. I myself started using Ventoy on the recommendation of a friend. ![]() ![]() You can find Ventoy very handy if you work on formatting and repairing computers, or if you like to try out different Linux distros. You can also copy other files to drive, so you can continue to use it for other purposes. With Ventoy, you don’t need to format the drive again and again: you can copy and delete ISO images as you wish. Besides that, tools usually prevent the drive from being used for other purposes (it’s not possible to copy other files). That way, you need to reformat the drive every time you want to boot another ISO image. Ventoy supports legacy BIOS and UEFI (with and without secure boot), MBR and GPT partition tables, which makes it kind of universal.Ĭommonly, tools to create bootable USB drives extract the ISO image contents to the drive, allowing just one ISO image to be used at a time.

The oddest quirk of the find/Replace Regex is the use of curly brackets to denote a capturing group. Formatting results? Yes, the results in the result pane can quickly be turned into HTML or SQL Insertion code using a RegEx search and replace, though this is often easiest done in a more specialised programmers’ text editor. Although it is definitely possible to type RegEx strings directly into the Find Box and have them work perfectly, a library of RegEx strings can save a lot of time for routine tidying up of SQL code, or formatting the results. So is it any use?Įven though it is odd, and lacks some of the features one expects, it is still very handy, particularly if you have a few RegEx favourites squirreled away.

Where he discusses that a bastion host is a security-hardened server, which should be the strongest and the last checkpoint in a networkīefore the access is allowed to the internal network or internally hosted application. Ranum in his 1993 article on the topic "Thinking About Firewall," The term "bastion hosts" was initially used by Marcus J. Servers such as OpenSSH server or RDP gateway. Bastion hosts (Bastion 1.0)īastion hosts (also commonly called bastion servers) are typically configured with a bare minimum operating system with protocol-specific The concept of bastions can be applied to the real life fortification of a place or a building or a computer network.

Bastions are still the recommended solution to manage secure remote access to cloud infrastructures. On the other hand, since Lilith is the big bad and it may be that Rathma’s helping her, Necromancers might end up on the wrong side of this whole thing. So there’s no reason a class couldn’t appear in Resurrected and Immortal and not still appear in Diablo 4, and there’s a significant storytelling aspect of this game - the return of Lilith, the mother of Sanctuary as well as the direct mother of Linarian/Rathma, the inspiration for the Priests of Rathma that all Diablo Necromancers come from. ![]() But that doesn’t mean much - clearly the Druid will be in Resurrected as well, and the Barbarian’s in both Immortal and Resurrected, as well as having appeared in Diablo 3 - at this point the Barbarian is the class that’s appeared in the most Diablo games, with appearances in D2, D3, and Diablo Immortal as well as Diablo 4. Now, the Necromancer and Crusader both appear in Diablo Immortal, and the Paladin will be making their return in Diablo 2: Resurrected. Two possibilities come to mind for me: the summoning-minion approach of the Necromancer or Witch Doctor, and the divinely powered fury of the Paladin or Crusader. With the Rogue basically filling the roles that both Amazons and Assassins filled in Diablo 2 and the Monk and Demon Hunter roles from Diablo 3, what’s next? What have other Diablo games provided that this game doesn’t yet? What does the game need? What role isn’t being filled? The Barbarian and Druid provide tankiness, the Sorcerer/Sorceress has moves to escape and evade damage and keep their distance, and the Rogue is able to switch between the ranged and melee approaches and evade damage with a variety of tricks. Right now, we have a pure melee in the Barbarian, a shapeshifter ranged/melee hybrid in the Druid, a pure ranged magic class with the Sorceress, and a hybrid melee/ranged with the Rogue. What does Diablo 4 need from its next class? So it’s entirely possible that there’s already a road map for future content and expansions for the game, and we might indeed see more than five classes before it’s all said and done.īut if we assume that we’re getting five at launch, that still leaves us with the question: Which one is next? What will that fifth class for Diablo 4 be, and when will we find out about it?Ĭlearly I do not actually know. We’ve been told that the Greater and Lesser Evils - menaces like Ba’al, Mephisto, and Diablo himself - will not be showing themselves immediately when the game comes out, leaving center stage for Lilith and her plans for Sanctuary. Now, it’s true that currently on the official site there’s only one silhouette left around that campfire, indicating that we’ll probably only see five classes at launch.īut Diablo 4 aims to be a much larger, more sophisticated game with more open-world elements than its predecessors. But since hearing Game Director Luis Barriga and Art Director John Mueller say repeatedly during that video that “There’s always room at the campfire” when discussing the game - and that iconic point of light in the darkness that serves as the character class-selection pane for the game - I’ve been wondering. ![]() Before I saw the Diablo 4: What’s Next?video during BlizzConline, I was of the opinion - based on what was said at BlizzCon 2019 - that we would be getting five playable classes for Diablo 4 in total. ![]() These programs cover essential topics such as responsible alcohol service, identifying fake IDs, managing intoxicated customers, and understanding liquor laws. Completing the Alcohol Training ProgramĬompleting an alcohol training program is crucial in obtaining a bartending license. Even if the state does not have a requirement, many employers will want staff to have server training in responsible selling alcohol. If a jurisdiction has a list of approved providers, you can find them on the state’s alcoholic beverage control website.Īlso, while some states have no state laws on being certified, cities in their state may have requirements, for instance, Nevada and Las Vegas. These approved providers offer courses designed to equip aspiring bartenders with the necessary knowledge and skills required in the industry.

DO NOT pay a bartending school $1,200 for a “bartending license” just because they tell you that you need one! The license you just paid for may be worth absolutely nothing! So what is the takeaway? Learn the rules an regulations of the city/ state you live in and act accordingly. (Obviously this is not a “bartending license” because its for servers and managers too). The thing to understand is that this is required of ALL STAFF who handles alcohol: that includes servers, managers, hosts, etc. For example, in Florida, anyone handling or service alcohol must attend “Responsible Vendors” courses in which a instructor teaches and advises proper ways or ID-ing guests, cutting off intoxicated people, etc. That being said, most states do have requirements for people serving alcohol. It is not a state required “bartending license”. This “bartending license”, however, is merely a certification that they will provide you with once you have paid them their money and taken there course. Now let me explain: Many bartending schools will tell you that they will get you your “bartending license” if you sign on with them. The truth: NO STATES REQUIRE A SPECIFIC BARTENDING LICENSE. Many people think that, by law, depending on the state or city they live in, they NEED to get a license to step behind the bar. |
