Pictures for reuse

I'm doing a school project, and one of the criterion is that I need to have pictures that are high quality that I can reuse. I cannot find good pictures in Creative Commons because many of them are just pictures from a museum. I'm looking for pictures relating to seismology. To clarify, I am not asking for anyone to find these pictures for me, but I would appreciate some helpful sites since I am new to this. If it helps, I am using these pictures for noncommercial educational purposes. I am not entirely sure where this question should go, but computers sounds like it would most closely relate to finding pictures online. NerdyPerson (talk) 02:31, 7 April 2017 (UTC)[reply]

What's wrong with Google? It's non-commercial after all. Thanks ツ Jenova 20 ^(email) 11:32, 7 April 2017 (UTC)[reply]

@Jenova20: Copyright violations have become fashionable with the internet because of the ease with which they are made, but it does not make them any more legal. (Whether copyright laws that make everything copyrighted by default are sensible is another debate, but it is what it is.) Listening to music you downloaded off The Pirate Bay is if anything "less illegal" than copying pictures from the internet to put them in a project that other people will look at, commercial or not. Tigraan^{Click here to contact me} 11:54, 7 April 2017 (UTC)[reply]

It is not clear what exactly you want, but you can try on Wikimedia Commons. Everything there is under a free license. You will find diagrams such as commons:File:Love_wave.svg in .svg format, i.e. vector graphics with an infinitely good resolution, as well as photographs. Tigraan^{Click here to contact me} 11:54, 7 April 2017 (UTC)[reply]

@Tigraan: I have changed the link to a Love wave so that it directly leads to Commons.

@NerdyPerson: I'd suggest visiting commons:Category:Seismology. --CiaPan (talk) 12:38, 7 April 2017 (UTC)[reply]

Funny enough my media studies course relied on us taking pictures from Google to create fake magazine covers. It was obscure and we never put them on the internet after though. That was my point. It's not legal, but nor are you likely to be prosecuted for it since everyone is sharing copyrighted pictures. Thanks ツ Jenova 20 ^(email) 12:58, 7 April 2017 (UTC)[reply]

I think this part of the discussion is missing the point. If someone already had "one of the criterion is that I need to have pictures that are high quality that I can reuse" specified as part of their school project requirements, then failing to fulfill this criterion is not a good idea. It doesn't matter whether or not it's illegal, whether or not you're likely to be prosecuted nor what other random people did in their media studies course without such criterion. Ultimately none of these are any comfort when you get a lesser or even failing grade because you failed to fulfill the project requirements. The only real relevance is that if such criterion really have zero reasoning behind them you may have a greater chance of challenging them. That said, in any such case you always have to consider whether you want to bother with such an effort and of course you're more likely to succeeed if you you challenge before hand rather than just failing to fulfill the requirements than saying there was no reason for them. And of course the circumstances of this case suggest you're not likely to succeed whatever you do, the lack of "prosecution" and everyone else doing it, or at least some people doing it on their project not withstanding. (Prosecution is the wrong word here anyway. In many countries this won't be a criminal matter and you can't be prosecuted for it. You could be sued for it and at a minimum the copyright owner could prevent you from publishing any further copies. Unless you have a reason allowed in law to do so without the copyright holders permission.) Nil Einne (talk) 13:33, 8 April 2017 (UTC)[reply]

Nil Einee is correct, but I have been able to find some pictures on Google and Wikipedia Commons with a Reuse license thanks to all of your answers. Thank you so much! NerdyPerson (talk) 17:35, 8 April 2017 (UTC)[reply]

You might start at our seismology article and follow links from there, copying any pics you want to use along the way (you may have to click on them several times to get to the max resolution). StuRat (talk) 18:18, 8 April 2017 (UTC)[reply]

Event-driven, data-driven programming, any other <something else>-driven?

xyz-driven sounds buzzwordy to me, but I've heard functional programming described as "value-oriented" or "value driven". Functional reactive programming is implemented with events under the covers, but it's supposed to model continuous time, so I'd class it differently from event- or data-driven programming. 50.0.136.56 (talk) 05:24, 8 April 2017 (UTC)[reply]

There's also Time-driven programming. I've occasionally seen "State Driven programming" to describe using state machines, but that strikes me as an attempt to force a buzzword and isn't used often.

Of course, your development process itself can be buzzword driven too! You can have Test-driven development, Model-driven engineering, Domain-driven design, Responsibility-driven design, and who knows how many others. ApLundell (talk) 15:05, 10 April 2017 (UTC)[reply]

public DNS with AWS

Google runs a public DNS that's both free and fast at 8.8.8.8 (and memorable too). I use it for my home computers.

Is there a similar thing from Amazon? I have some servers hosted on Amazon's AWS EC2 service, and it would be great if I can get the same service as 8.8.8.8 within AWS's own infrastructure to reduce latency. ECS LIVA Z (talk) 18:02, 7 April 2017 (UTC)[reply]

Do you actually have evidence that DNS latency is an issue for you? Your application must be doing an extremely large number of DNS lookups to many different domains for this to be a problem. If that's really the case, you may want to look at Amazon Route 53. CodeTalker (talk) 02:27, 8 April 2017 (UTC)[reply]

Route 53 is AWS's DNS service and is probably the fastest within AWS. It's not free but it's cheap enough that its cost shouldn't bother you unless your query load is insane. 50.0.136.56 (talk) 05:26, 8 April 2017 (UTC)[reply]

Please correct me if I'm wrong, but Google's 8.8.8.8 role is telling me "If you want to go to wikipedia.org, head to this IP". Wikipedia pays someone to "map wikipedia.org to IP", but it's not Google.

Route 53 is the "map custom domain name to IP address" service, so it 1. is not free, and 2. is meant to service custom domain names owned the payee. I don't have a custom domain name in this case. I just want to find out the IP address of existing sites on the internet. So I don't think Route 53, whether free or not, is suitable for this role. ECS LIVA Z (talk) 23:17, 8 April 2017 (UTC)[reply]

DNS has two aspects: one is to be a trusted, albeit only local, registry which publishes the fact that "I control the example.org domain and I state that enquiries for it should be routed to IP 1.2.3.4". This is a low volume service that does not handle requests to resolve a domain name, merely to serve other DNS services.

The second aspect is servicing the client requests "where do I connect to example.org?", in bulk. This is a replicated service, based on trust. My DNS requests from my desktop might be handled by a machine on my own private network, my broadband router, my ISP, backbone host services, the domain's hosting company and name registrar in turn. This is largely a problem for the client to pay for, as close to that client as they can arrange it. This is a performance critical service.

My own DNS (i.e. the first registration aspect) was historically handled through my domain name registrar, with subdomains within this via my hosting company. Nowadays I'm migrating to Amazon AWS and Route 53. Not because it works better, but because it is easier to manage (Route 53 is a good product and perhaps "the best way to deal with DNS" for many of us) and more flexible for me, as a host rather than a client. This is (IMHE) true both for myself (my site hosting is migrating to AWS too) and also even for those who only need DNS services and are still hosting elsewhere. Andy Dingley (talk) 15:12, 9 April 2017 (UTC)[reply]

There is an Amazon provided DNS server for use by Amazon cloud apps. Information is here, in the documentation. I'm surprised your server wasn't already configured to use this DNS provider when you got it.

I agree with CodeTalker that you must have an unusual application if DNS latency is a big issue for you, and unless you're making an unusual amount of DNS lookups there's probably another problem. ApLundell (talk) 14:46, 10 April 2017 (UTC)[reply]

A spreadsheet question

In a spreadsheet, is there a way to format a cell so that when you click it, it brings you to the what is in the cell? I mean, if cell A1 contains "=A3", I would like to be able to click A1 and it jumps me to A3. Cheers. Anna Frodesiak (talk) 20:19, 8 April 2017 (UTC)[reply]

There are many different spreadsheet programs, which all work differently, so there's no one answer that will be correct for all possible spreadsheet programs. If you're using Excel, take a look at this link: [1]. If you're using a different spreadsheet, you need to specify which one you're using. CodeTalker (talk) 20:59, 8 April 2017 (UTC)[reply]

Hi CodeTalker. A thousand pardons. I am using OpenOffice. And holy moly, the stackoverflow link you provided is way beyond my ability to understand. I thought there might just be a command or something. Best, Anna Frodesiak (talk) 21:12, 8 April 2017 (UTC)[reply]

Wouldn't that behavior look like a bug to anyone who doesn't know that A1=A3 ? StuRat (talk) 23:10, 8 April 2017 (UTC)[reply]

Well, StuRat, good point. Actually, it is just for me. I have a list at the beginning of the sheet. Each cell contains =BA1 then the next cell down contains =CA1 then =DA1 then =EA1, etc. BA1 is the text heading of a table there. So, the display at the beginning of the sheet is a sort of index or table of contents of what all the tables are. I would like to be able to click one of those at the beginning of the sheet and magically get taken to that particular table. Anna Frodesiak (talk) 23:54, 8 April 2017 (UTC)[reply]

It seems what you need is a Table of contents, but Calc spreadsheets for some reason can't have a TOC like Writer documents. You can use Outlines (Data->Group and outline->Group) to selectively conceal sets of rows or columns. You'll get a vertical or horizontal bar with tiny + and - buttons on it that you can use to expand that part of the table. This is similar to folding.

that said, it is possible to do what you describe by having a macro that sets the focus to a particular cell. However, the macro would have to be assigned to something like a hyperlink or a button - clicking on a cell alone can't invoke a macro (without contortions...) This seems to work:

Sub gotoCell


sheet = ThisComponent.Sheets(0)
targ = Sheet.getCellByPosition(0,2).string 'A3
ThisComponent.CurrentController.select(Sheet.getCellRangeByName(targ))
End sub

This transfers you to the cell whose coordinates are in cell A3. you'd have to manually insert this into the spreadsheet (Tools->Macros->Organize macros->LibreOffice Basic), then draw a button (View->Toolbars->Form controls), then set the button's "Execute action" event (right click->Form controls->Events) to "gotoCell".

I played with OO once. It's completely over-engineered and evil (esp. UNO - the macro above uses only Basic, though) Asmrulz (talk) 15:41, 9 April 2017 (UTC)[reply]

Thank you very much, my friend, for taking the time. It is so far beyond my mental pay grade, you wouldn't believe. I must give up on this quest. I must say that it is odd. I am often at a cell that contains something like "=AD37" and would like to jump there to see what is in that cell. These spreadsheets should have a hotkey or something that does that. Thank you again, and best wishes. :) Anna Frodesiak (talk) 22:40, 9 April 2017 (UTC)[reply]

Similarity to the C programming language

C#, Java, Python, Objective-C. Which of these, will you suggest, is most related to the C language, by all possible means (syntax, logic, internal functions, error handling, applications). Thank you, Ben-Yeudith (talk) 01:09, 9 April 2017 (UTC)[reply]

Plainly Objective-C, as the only one that is a superset of C. (You didn't ask to order them, but:) Python is the most removed (no braces, and it and C# have no non-object primitive types). I think C# is a bit farther from C than Java is (simply because it contains more special syntactic constructs). --Tardis (talk) 04:26, 9 April 2017 (UTC)[reply]

I agree with User:Tardis, with the caveat that If you knew only C, you might find Objective-C's message-passing syntax a bit mystifying. ApLundell (talk) 18:44, 10 April 2017 (UTC)[reply]

Personally, I find Malbolge to be a wonderfully intuitive variant of C and highly recommend it.

In all seriousness, I agree as well. I'd rank them in descending order based on their similarities to C as: Obj-C, Java, C# and Python (with C++ in there right behind Obj-C if you wanted to add the most obvious C-variant). ᛗᛁᛟᛚᚾᛁᚱPants Tell me all about it. 20:14, 10 April 2017 (UTC)[reply]

I am trying to remember the name of a program

I am trying to remember the name of a program that you run to set many windows 10 professional options to maximize privacy, remove the "Get Office" and "XBox" ads from the start menu, stop trying to get you to buy a OneDrive subscription, etc. I have a list of these sort of things things I do when I do a new install, and I have been meaning to try a program that automates most of that.

The thing is, I can't remember the nam of the program, or any similar program (which will lead me to where I want to go with some clever "alternative to", "comparison", and "shootout" searches). Anyone have any idea what it is called? --Guy Macon (talk) 13:47, 9 April 2017 (UTC)[reply]

calculate angle on image

Is there a way to calculate the (approximate) angle at which these two thick black lines meet[2]? Doesn't have to be precise, plus minus 2 or 3 degrees is fine. ECS LIVA Z (talk) 00:19, 12 April 2017 (UTC)[reply]

Slap a protractor on it and read the answer. StuRat (talk) 01:06, 12 April 2017 (UTC)[reply]

The upper line is 45.48 degrees. The lower line is 74.41 degrees. Open the image in a photo editor (I used Gimp) and use a measuring tool to calculate the angles. The angle between them is 28.93 degrees. 71.85.51.150 (talk) 01:07, 12 April 2017 (UTC)[reply]

Uh wait, the angle between them is clearly more than 90deg.

Sturat's "slap a protractor on the screen" method gives me roughly 140deg (Perhaps you subtracted when you should have added?) ApLundell (talk) 02:06, 12 April 2017 (UTC)[reply]

They will add up to 180° so if you measure one you can calculate the other. If your measuring tool doesn't do angles, you can still possibly get the pixel coordinates and then figure out the angles with trigonometry. 50.0.136.56 (talk) 16:35, 12 April 2017 (UTC)[reply]

Local machine IP extended to a virtual machine cause conflict?

I have a local machine with Win10 from which I mean to run a Linux virtual machine (LVM) with an OpenSSH server (there is a reason why I consider an LVM instead of WSL, in this case). Now, here's what I want to ask:

I have my IP address which is permanent. As far as I know, this IP comes from my ISP, and due to that, if I'll install an LVM on my local it will have the same IP as the host machine.

Let's assume I have the same IP both on the host machine and LVM: How then could I SSH tunnel into both without creating some kind of conflict? That is, both has the same ISP-provided IP address, so how could I avoid conflict? Ben-Yeudith (talk) 04:53, 12 April 2017 (UTC)[reply]

You can not have the same IP address on both of them. Your LVM will have a different IP probably in a 192.168.*.* range. Then either the host OS or your wi-fi router (if you use one) will translate it into the external provider assigned IP. Ruslik_Zero 08:42, 12 April 2017 (UTC)[reply]

In terms of enabling remote SSH, these easiest thing to do is probably to choose different ports for the SSH in each computer and make sure you set up port forwarding correctly. I'm assumign you're not behind CGNAT or anything else that will make things difficult and either your router or host OS (whichever is reponsible, or both) supports forwarding properly. Nil Einne (talk) 09:44, 12 April 2017 (UTC)[reply]

Yes, port forwarding is the answer. Your LVM will configure a virtual network interface that will listen for traffic on your host machine's localhost and forward it as appropriate. On VirtualBox, you can do this with the Network Address Translation option on the guest machine: I like to set it up to forward an otherwise-unused port such as 2222 for my OpenSSH server on the guest.OldTimeNESter (talk) 13:11, 12 April 2017 (UTC)[reply]
