== Licensing MS SQL Server ? ==

For many years I have had my own MS SQL Server. I got it through a MS program which was sort of training. You paid about 1,500 a year or so and MS would give you access to a bunch of software: servers, language compilers, etc. It was all raw, that is you had to build applications of your choosing. I used it to design a database in C# and SQL Server. They imposed limitations. You could not use that stuff commercially. I never did,

Well, now I have a need to really purchase a new SQL Server. I went to MS website and found that a standard edition will cost me 860 some dollars. This is not all. It turns out I need a license to run it. In order to purchase a license, I need to know how many cores my new SQL Server will have. I never had any ideas that SQL Server should have cores. Hardware, like a processor, yes, but the Server, no. Anyhow, a girl in service of MS quickly calculated that my SQL Server will cost me almost 6,000 dollars.

I used to like MS, not anymore. I have other complaints also, but let's focus on this. Why do they say in one place that I need to pay $860 and then hang a license on it? Is it a rip-off? I also do not understand the concept of cores when applied to software, not hardware. I need help.

Schedule a daily google search

Is there a way to schedule a google search to be done once every day on a few keywords, and notify me if it finds a page that matches those search terms? (I searched and didn't find anything, except scheduling Google Calendar events.) Bubba73 You talkin' to me? 04:11, 9 May 2023 (UTC)[reply]

Is there a way to detect that a news website is a "News" website?

Does the HTML source code of news websites include any special or distinctive HTML tag or HTML tag attribute that indicates something like "Hey there! This website is primarily about news and is part of the mass media!"?

Thanks. 2A10:8012:17:CDC6:D066:AC47:1958:9121 (talk) 20:16, 10 May 2023 (UTC)[reply]

They will typically have meta tags for description and keywords identifying themselves as news sources. For example, for The New York Times, their website www.nytimes.com has (slightly simplified), <meta name="description" content="Live news, investigations, opinion, photos and video by the journalists of The New York Times from more than 150 countries around the world. Subscribe for coverage of U.S. and international news, politics, business, technology, science, health, arts, sports and more."/>  and  <meta name="keywords" content="news, live updates, latest news, breaking news, local news, current events, top stories, livestream, live video, world news, us news"/>. For the BBC at www.bbc.com we find, more concisely, <meta name="description" content="Breaking news, sport, TV, radio and a whole lot more. The BBC informs, educates and entertains - wherever you are, whatever your age."/>  and  <meta name="keywords" content="BBC, bbc.co.uk, bbc.com, Search, British Broadcasting Corporation, BBC iPlayer, BBCi"/>. None of this is standardized, and nothing prevents Joe Shmoe from Podunk to set up a website advertizing itself as the go to place for in-depth reporting of the latest news from all over the world.  --Lambiam 12:01, 11 May 2023 (UTC)[reply]

Detecting whether a website is a "News" website based solely on the HTML source code can be challenging and not always reliable. While some news websites may include specific HTML tags or attributes indicating their nature, there is no standardized or universal tag that all news websites must use.
However, you can look for certain elements in the HTML source code that might suggest a website is focused on news. Here are a few common indicators:
Meta Tags: As you mentioned, news websites often include meta tags for description and keywords that identify themselves as news sources. These tags may contain keywords like "news," "breaking news," "current events," etc.
Structured Data Markup: Some news websites implement structured data markup, such as schema.org's NewsArticle markup, to provide structured information about their articles. This markup can include properties like headline, date published, author, and more.
RSS Feeds: Many news websites offer RSS feeds that allow users to subscribe to their content. Look for <link> tags with type="application/rss+xml" or type="application/atom+xml" attributes, which can indicate the presence of an RSS feed.
URL Structure: News websites often have URLs that reflect their news sections or categories. For example, a URL like "news.example.com" or "example.com/news" may suggest a news-oriented website.
Content Markup: News articles on reputable news websites often follow a specific content structure. Look for HTML tags commonly used in news articles, such as <h1>for headlines, <p> for paragraphs, <time> for publication dates, and <cite> for article sources.
It's important to note that these indicators are not foolproof and may vary from website to website. Additionally, some websites may not have clear indicators or may use generic tags that are not specific to news. Therefore, it's advisable to consider multiple factors, including the website's branding, content, and reputation, when determining if a website is a reliable news source.

Regex help requested

Wasn't sure whether to take this to Wikipedia:Request a query, Wikipedia:Help desk, or here. Landed here.

I'm tryna search wikipedia for articles containing Template:Infobox royalty where the clan_name parameter is non-empty. I used to speak regex twenty years ago, to the point where I once wrote my own parser, but my memory is failing me here. I know my search is supposed to start with hastemplate:"Infobox royalty" insource=/clan_name..., but my efforts to complete the regex in such a way that returns how I'm wanting have led only to results where clan_name is defined but null, and empty sets. Assistance would be appreciated. Shamefully, Folly Mox (talk) 16:38, 14 May 2023 (UTC)[reply]

I haven't use regex in a Wikipedia search. In basic regex, you want something like "clan_name\s*=\s*\w", which demands "clan_name" followed by zero or more spaces followed by "=" followed by zero or more spaces followed by a word character. But, without a reference to the interpreter, it is difficult to know if it uses \s for space and \w for word character. 97.82.165.112 (talk) 12:25, 15 May 2023 (UTC)[reply]
I don't know if \s and \w work in Wikipedia regexes either, but if they don't, you should be able to use something like
clan_name *= *[^ ]

solar panels free

which company in california offers the best free solar panels not with just no net cost but without hidden fees or other costs of not being able to sell the power back to the grid, which one can we do it with that connects everything from the roof and requires no cutting holes in the roof just connecting to our main electric line or smart meter any ideas my mom keeps seeing commercials about free solar systems for californias ive heard of solar richmond but do not know if they are the ones to go with anyone better out there 2600:1700:9758:7D90:C5BF:5F1C:A46C:C83A (talk) 21:18, 15 May 2023 (UTC)[reply]

Those companies have to make money somehow. So what they do is give a loan with no upfront cost. But then you have to pay them a regular repayment to pay back the loan, hopefully your electricity is included in the deal. It will depend on the kind of roof you have if holes have to be drilled. But the answer to your question is that NO company is just going to do it for no money. Graeme Bartlett (talk) 23:56, 15 May 2023 (UTC)[reply]

even with a government subsidy i keep seeing commericals on youtube for free solar programs — Preceding unsigned comment added by 2600:1700:9758:7D90:C5BF:5F1C:A46C:C83A (talk) 00:03, 16 May 2023 (UTC)[reply]

Depending on where you live, what you purchase, and who you purchase from, you can get a tax rebate of up to 30% the cost of the hardware. Do not expect to get 30%. Expect something far below, such as the average of 7% that I would get where I live. Further, it is not "free money." It is a tax rebate. On my tax return, I claim the cost of the hardware and I get to deduct that from my taxable income, which can lower the amount of tax that I owe the government. As for YouTube, you must understand how it works. Joe makes a YouTube video. If enough people watch the video, YouTube pays Joe. It doesn't matter if Joe's video is accurate or correct or ethical or makes sense in any way. All Joe wants is for people to click on the video so he makes money. He gets more clicks with a video that claims you can solar panels absolutely free than a video that says you might get up to a 30% tax rebate on the hardware. 12.116.29.106 (talk) 12:10, 16 May 2023 (UTC)[reply]

There are many programs that can be used to download and save the audio from a Youtube file. Which one you want is highly dependent on your operating system. 12.116.29.106 (talk) 12:23, 16 May 2023 (UTC)[reply]

Why 2FA such as Google Authenticator is safe? If I know someone's password, open a bunch of programs to submit all the codes generated in one minute to make a Brute-force attack, is it still safe? -Lemonaka‎ 07:55, 17 May 2023 (UTC)[reply]

Generally you cannot submit more than a few codes a minute (say 6 or so) and the code to use changes every 30 seconds. So theoretically you could get lucky, but your chances won't be very high. Not sure what the opening of a bunch of programs has to do with it.... —TheDJ (talkcontribs) 09:27, 17 May 2023 (UTC)[reply]
It appears that the suggestion is to open 10,000 instances of the login for some secured application and automate the process of logging in with a username and password and then have each of the 10,000 instances try every possible 2FA sequence from 0000 to 9999 all at the same time. One of them (technnically 2 to 4 of them) will get it correct. If the backend is developed by someone who doesn't know what they are doing, this could work. The backend should recognize that the same username/password is being used 10,000 times all at once and each of those is waiting for 2FA at the same time. So, even if you use the correct 2FA, it won't be allowed. But, security is only as good as the ability of the person implementing it. 97.82.165.112 (talk) 13:03, 17 May 2023 (UTC)[reply]
