If you mean while it was running, that was a really dumb idea. Modern hard drives particularly 2.5" are far less sensitive to vibrations than old ones, but intentional misuse will still cause problems. It should be obvious from the specs, speed, a simple online search, weight, SMART, internal drive info etc etc whether it's an SSD or HD. (For that matter where did you even get this HD? Unless you're randomly being given devices, it should be obvious from the price, or if it isn't you really need to do more research before buying stuff.) If you mean when it was disconnected, then provided it's really a small shake that was probably harmless and the noise may be an indication it can't be trusted.

You could host your images on a public site like Imgur. Personally I'd host the images there and host the page(s) on a site like CodePen or JSfiddle; you'll have to use the full URLs that Imgur generated for your images when you refer to them from your email, or a site like Codepen. If you really had no alternative, you could embed the image into the HTML using the Data URI scheme (possibly using a tool like this to generate the encoded text), but for all but trivial images that produces horrifically unreadable HTML code (which matters if your teacher intends to manually read the HTML source text). -- Finlay McWalter··–·Talk 14:44, 11 June 2016 (UTC)[reply]
Or you could zip the HTML, images and folder structure? --Tagishsimon (talk) 16:14, 11 June 2016 (UTC)[reply]
Yes, zipping the files is a better solution. The whole thing is then self contained and doesn't depend on external servers. Just put all the files in one folder, make sure it works there, and then run zip on the folder to create a zip file and send the zip file to your teacher.

The links will work if you used relative links and not absolute links. If you links C:/users/aryan/My Photos/school/coolimage.JPG then it will not work. If you used coolimage.jpg and the image is in the same folder is the HTML file, then it will work. 199.15.144.250 (talk) 13:45, 13 June 2016 (UTC)[reply]

hey please answer my request.

Hello, i wanted to know what i have to do to own an lte network. I searched the internet but nothing regarding my searches. I mean what do i have to buy?, from who?, and how much is it going to cost me actually. Please specify exactly what i have to buy to start a 4g lte network (for business). — Preceding unsigned comment added by 197.210.16.20 (talk) 09:06, 11 June 2016 (UTC)[reply]

In most places you need a license from the government. And you can't get one unless you have billions of USD to buy out a company with an existing license. Cellular networks (like 4G LTE) use regulated frequencies. Things like Wi-Fi and Bluetooth use unregulated frequencies, which is why anyone can buy devices transmitting on those frequencies. --71.110.8.102 (talk) 09:11, 11 June 2016 (UTC)[reply]
Self-pedantry: what I really meant was "base stations transmitting on those frequencies". Of course anyone can buy a cellular device that transmits on LTE frequencies, but only devices that act as "clients". --71.110.8.102 (talk) 23:25, 11 June 2016 (UTC)[reply]
There are areas that are currently not covered and may be licensed. The reason is that there are still some areas with no cities or main roads. So, there is no reason to put in a cell tower to cover the area. As an example, most of Alaska is not covered. You can probably get a license to put up a tower in the middle of nowhere pretty cheap.
However - I think that the questioner thinks that he can buy a tower, drop it in his backyard, and suddenly the phone companies will come and pay him to use it. That won't happen. What you can do is lease land for the phone company to use so they can put up their own tower. They prefer very tall buildings or very open farmland. If you have either, then they probably already contacted you. 199.15.144.250 (talk) 12:05, 13 June 2016 (UTC)[reply]
That's very common around here in Vermont. Many farmers have cell phone antennas on their grain silos. I figure that there are so many because there are so many mountains getting in the way. Getting towers, be they cell phone, TV, or wind turbines, put up on mountain ridges around here is a long painful process. Dismas|(talk) 12:51, 13 June 2016 (UTC)[reply]

Free Zip Password Recovery

I’m using the entitled software for days now, I’m wondering if it’s worth the time and energy, and electric bill. What are the chances of the software’s success?

Notes (The following appears on the software window):

Recovery type: Brute-force

Charset: – I’ve ticked them all excluding the box Custom (user defined)

Status:

Processed: [length: 5]

Average speed: something around 1500-2000psw/sec

Apostle (talk) 18:33, 12 June 2016 (UTC)[reply]

The chances of the software's succes are probably close to 100%... if you have an infinite amount of time!
A password like "AA" or "10" can be bruteforced very quickly. But it will take a very very long amount of time to bruteforce a password like "&%&^%*&&(*&()SDHISUH#&*(^$*&^*Y*89739487930847&*^^%^%%^SU(((&&^((^^!!@@@@".
Because we do not know what the password is it is very difficult to estimate the amount of time required to bruteforce it (although we do know that most passwords are quite short). If you created the ZIP file then you probably know what characters are likely to appear in it. For example, in my native language diacritics are rare compared to some other languages, and I never use them in passwords. But in Germany it is far more likely to see a password that contains a ü (U-umlaut).
Because you have chosen all charsets it may take very very long; OTOH if you select (for example) alphanumeric only then the software cannot find the password if it contains a character that isn't alphanumeric. If you created the file then you probably know which characters you've most likely used in the password. If you downloaded the file from the internet then I would recommend Googling the filename. Another option is to try if the URL of the site you downloaded it from is the password (which is common on certain download sites). If you want to learn more about password cracking then I would recommend downloading Extreme GPU Bruteforcer by InsidePro. Unfortunately I don't think it works on ZIP files, but it may be interesting to you nonetheless. The Quixotic Potato (talk) 05:54, 13 June 2016 (UTC)[reply]

I agree this question is only answerable by the OP. Notably, for many people whether or not it's worth it is going to depend significantly on the content. If it's your only copy of certain highly prized photos of you deceased parent/child/spouse, people are going to be wiling to spend a lot more effort than they would if it's some warez who's password you couldn't find and for all you know it's not even what you believe it do be. Yet even within these, people's value judgements are going to vary. In addition, any info you know about the password should inform your password cracking solutions and judgements.

IMO the best thing to do would be to calculate the amount of time it would take for password of various lengths for various logical combinations (e.g. all low caps alphanumeric) and set a cut of point which you feel fits your requirements. While cut off points at character limits are often no more arbitary than another random point (unless you have some reason to think it will be that many characters), they're a simple point. Give the rate of increase by adding a character, it shouldn't really be that hard to decide. E.g. maybe 5 days is resonable but 4 months is not and these could easily be one character difference. (Of course if these are maximum times and your certain the password is under that length your average time would be half that.) It may make sense to choose different combinations e.g. all low caps alphanumeric, only numeric depending on precisely what you think you know about the password.

Nil Einne (talk) 09:22, 13 June 2016 (UTC)[reply]

P.S. Another alternative would be to define a cut off point in time, e.g. give up after 4 weeks. But two issues I can see with this are that you may not make the best decisions about which passwords to try in that time, and also I think some people would have a tendency to leave it since maybe it'll be next and you stopped just at the wrong time (and so on and so on). While there isn't intrisicly wrong with keeping going, ultimately if it isn't worth it trying forever you've got to stop at some stage. And which this could happen even if you plan to stop at a certain number of characters, when you're thinking of it in terms of doing all those characters and so the contrast in time is very high, you're probably less likely to just keep going since it could be next. Nil Einne (talk) 13:23, 13 June 2016 (UTC)[reply]
Noted. Thank you both. Love you guys -- Apostle (talk) 19:27, 13 June 2016 (UTC)[reply]
See the article about Password cracking. How does a general-purpose brute force ZIP password search program detect when it has found the correct password ? AllBestFaith (talk) 21:55, 13 June 2016 (UTC)[reply]
If checking all of the "charset" boxes makes it try all 95 ASCII characters, then at 2000 passwords/second it will take 95n/2000 seconds to check all passwords of length n. That's 45 days for length 5, 4254 days for length 6, 404130 days for length 7, and so on, increasing by a factor of 95 each time.
You would be much more likely to find the password if you used a program that ordered passwords by some more sophisticated measure of plausibility than length. For example, a good password cracker would try "password123" before "!JU$". See if the program you're using has a dictionary cracking mode, and try that instead.
2000 passwords per second is very slow. This program allegedly manages 36,500 p/s on a high-end CPU from 2009, or 1,150,000 p/s on a high-end GPU from 2009. It's commercial, but you can probably find free software with similar CPU performance (maybe not GPU).
It may be worth pointing out that the original zip encryption was weak and could be cracked by a known-plaintext attack (and possibly still faster than brute force even without known plaintext, but I'm not sure). The Info-ZIP utility that is widely used on *ix systems never implemented modern (AES) encryption and doesn't even warn about the weak encryption, so it's possible that this zip file might be vulnerable to attack even if it was made recently. -- BenRG (talk) 00:58, 14 June 2016 (UTC)[reply]

Help sought

Most things I install and or uninstall adds its information at my ‘‘recovery’’ point, what I’m not happy about because my last successful ‘‘recovery’’ point will disappear. It occurred before… Sometimes it just disappears anyway if it becomes many months…

1) I sought a software, portable if possible, that helps mitigating this issue? – Say it saves/installs everything on the software rather than Programs option available on the Control Panel - Any other guidance would be helpful.

2) How do I go back to day one, before I used the first ‘‘recovery’’ point, rather than uninstalling and reinstalling Win7?

Library for calculating a phone number's, or generally any number's, memorability

I'm picking a new phone number. My carrier gave me a list of possible numbers to choose from. Since the list is quite large so choosing one by hand would be time consuming. Is there a Java/Python/JS library that can calculate a phone number's memorability? Here are some metrics that I'm interested in:

  • Number of runs of repeated digits, lengths of such runs ( 1111 )
  • Number and length of repeated patterns ( 121212 )
  • Number of unique digits (the lower the better)
  • Number of syllables when pronounced out loud (the lower the better)

Unless OP is running a business where they want potential customers to be able to remember the phone number from a commercial or ad jingle, I'd tend to agree. The only phone numbers that I remember are mine, my wife's, and my father's. And I only remember my father's because he still uses the land line we used as kids.

Not many people will need to remember my number, sure. But a more memorable number also has the benefit of being memorable for its owner. Johnson&Johnson&Son (talk) 13:02, 13 June 2016 (UTC)[reply]
In that case, maybe try to find a number that is just an anagram of the number that you had while growing up. That's what happened with my cell phone number. Completely by chance, I ended up with the last four digits being the same, though in a different order, from the last four of my phone number growing up. The prefix is different, of course, since I live in a different state now. Dismas|(talk) 22:52, 13 June 2016 (UTC)[reply]
... or, alternatively, choose a number that contains the digits of your birthday, or that of someone you know well. Dbfirs 07:12, 14 June 2016 (UTC)[reply]
The issue here is the assumption that remembering an abstract relationship between two things is easy. Instead of remembering 4 digits (since most places use very few options for the first 3 digits), the person is supposed to remember that, for no apparent reason, the 4 numbers are related to a birthday, or address, or some sort of anagram. Then, assuming that memory holds, who's birthday? What address? What order does the anagram go? Now, two difficult memories must be in place to have any chance of remembering 4 digits. In my opinion, it isn't patently "easier" to form abstract memories. For many (if not most) people, remembering 4 digits that are used frequently is easier. I remember the last four of all my phone numbers from the past (7443, 8161, 2000, and 2257) and I have a hard time remembering numbers. 199.15.144.250 (talk) 15:35, 14 June 2016 (UTC)[reply]
Like you, I can remember sequences of digits (including pi) just by learning them, but some people find this very difficult, whereas they can remember the dates of birthdays more easily. The association of a telephone number with a birthday seems almost effortless to many people, but perhaps not to all. Whatever works for you ... Dbfirs 08:02, 16 June 2016 (UTC)[reply]

Digital photo with varying focus

This generally isn't a high-quality photo; I took it while driving at comparatively low speed, and (as with most of my images) I had the camera on auto mode, not manual. I'm confused by the inconsistent focus: the center of the image is properly focused while the building's wings aren't (as is expected for such an image), but areas of the right wing are substantially blurrier than areas of the left wing that are no farther from the physical camera and no farther from the center of the image. See the two image notes I've added. Could someone help me understand why the focus is varying? Nyttend (talk) 02:03, 14 June 2016 (UTC)[reply]

A digital camera like that typically used in a phone doesn't take a photo in a literal "instant", it takes some fraction of a second to capture the image and it does so by scanning the field of view. This can lead to some strange effects, as this photo of a propeller illustrates. Also, after just a cursory examination, it actually appears to me that the car on front of the building is the most "in focus" thing, your camera might have focused to that, in which case I don't really see much inconsistency, the right wing IS the object farthest behind the car, so it's the most out of focus, the left wing is not that far behind so it appears less out of focus. Vespine (talk) 04:06, 14 June 2016 (UTC)[reply]
The image was taken with a Nikon D3200, according to the EXIF data. That's a DSLR with a shutter, so I don't think it's a scanning artifact. -- BenRG (talk) 07:39, 14 June 2016 (UTC)[reply]
DSLRs are not rolling shutter effect–proof... --CiaPan (talk) 08:09, 14 June 2016 (UTC)[reply]
You're right. I only meant that it can't be a CMOS scanning artifact, because the sensor isn't scanned until after the shutter is closed. But I don't think this can be related to the mechanical shutter either, because the D3200's shutter moves vertically ([3]). -- BenRG (talk) 21:09, 14 June 2016 (UTC)[reply]
Looks to me more like jpeg compression artifacts than out of focus. 91.155.193.199 (talk) 05:33, 14 June 2016 (UTC)[reply]
It's definitely blur, not JPEG artifacts. -- BenRG (talk) 07:39, 14 June 2016 (UTC)[reply]
Everything is blurred on the right, even the grass in the foreground. Also, the blurring seems to be linear, not circular (look at the white handicapped parking sign). So this is probably some sort of motion blur, not focus blur. -- BenRG (talk) 07:39, 14 June 2016 (UTC)[reply]
From the distance this image was shot from, 'landscape' auto-mode would have been better. The aperture would have shut down more, brining more of the background into focus. On a bright day like this, the ISO could have been increased to 200 without loss of quality. Some say that wide angle (in this case 42 mm) increases the depth-of-field - rubbish. Double up on ISO to keep the faster shutter speed, (since you where sooting it from a moving vehicle) and use landscape to ingress depth-of-field.. Auto-modes are useful when one only has a moment to point and shoot but they can't do everything for you. Landscape mode will (on a Nikon) do a good job of averaging the exposure too over the whole scene as well. The blur to the right and left is just down to the wide-angle and too large an aperture. Hope this helps Digital_camera_modes#Automatic_modes.Aspro (talk) 16:48, 14 June 2016 (UTC)[reply]
I don't think depth of field is the problem here. The picture was taken roughly from here. Here's how it looks in Street View. The blurred windows on the right are farther from the camera, but only by ~10–20%. The grass on the left is much closer to the camera and would be much blurrier than the windows if it was a DOF problem. Also, as I wrote above, the blurring appears to be linear, not circular.
If it's a motion blur (camera shake) problem, then of course what you need is a faster shutter speed, possibly combined with a larger aperture and/or higher ISO. -- BenRG (talk) 21:09, 14 June 2016 (UTC)[reply]

Selenium Webdriver

I am automating a form in which there is unique id field that generates ids randomly through regular expression. I need that random value to be captured and stored in the excel sheet for my own database so that I can perform edit and search on the same data further. Here I have given the code that is generating the ids

public class Regular  {

	final static String ALPHA_NUMERIC_STRING = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz 0123456789!@#$%^&*()_+-=<>?:\"{}|,./;'[]\'";
	public static String randomAlphaNumeric(int count) 
	{
	StringBuilder builder = new StringBuilder();
	while (count-- != 0) {
	int character = (int)(Math.random()*ALPHA_NUMERIC_STRING.length());
	builder.append(ALPHA_NUMERIC_STRING.charAt(character));
	}
	return builder.toString();
	}

}

It gets to the unique id field through the following code:

    enterTextField(UniqueCode,5,"Unique Code", Regular.randomAlphaNumeric(25));

route optimization combining Google Maps and Uber

For my project that I hope to use as a portfolio as part of my admissions to a boot camp, I am trying to write an app that include a route optimization feature that's always been on my wishlist. Now, right now I'm working on the more boring aspects of basic app development, but at my heart I'm trying to decide if my algorithm is possible at all.

Concept: As a resident of New York City, I often note there are many parts of desired trips where the subway for that route is much faster and efficient then a car along the route, especially for express trains (the A, D, E, F, Q, 4, 5 etc.) However, transfer times and hailing times for the Uber have to be factored in as well. Thus we could have two types of commuters: customers who mainly want to save time, but will trade a little time for money, as well as customers who want to save money, but willing to trade a little money for more time saved. It is also possible to save both, assuming transfer times work out, and this app should detect that. (Surges and UberPool can be dealt with at a later stage of development.)

  • Imagine customer A, who sets a budget of $20 for her trip (has an Unlimited Ride metro card), and but also wishes to maintain gains on time. However, customer A wants to stay below $20 (a little over is okay, this tolerance could be entered) and is willing to take as much public transit as possible in order for her Uber ride to cost roughly $20. She's coming from bars in the Village and doesn't want to spend 2.5 hours using late night (low-frequency) subway service getting home to Flushing, Queens, but doesn't want to spend a fortune either.
  • Imagine customer B, who sets a time budget of 45 minutes for his trip, and would rather not spend that much on an Uber ride especially if the Uber ride is going to take him through really traffic-jammed areas of the city, but will spend money on a ride to ensure that his ride stays under 45 minutes. (He's going to an important meeting.)
  • Another optimization feature would be to set a "time for money" or "money for time" conversion rate, i.e. "I am willing to spend $5 to save 15 minutes" or "I am willing to spend up to 20 minutes more to save $25

So my questions are: is such an optimization practical to implement? Is this an NP complete problem? (It sounds a little like the Knapsack problem.) I spoke to a CS major on the Megabus who didn't seem convinced it could be implemented easily. Would Uber be really mad if I was using their API frequently to try to estimate times for trips at various branch points of calculation without actually hailing a ride? To me it seems possible at least for an NYC implementation given that a) there a fixed amount of subway stops in NYC b) there are natural chokepoints in and out of the city (bridges, tunnels) c) the app could have a "common sense" feature that could be turned on so it would ignore jammed areas or lines reporting construction or delays, and also focus on expressways and express train routes as branch points for optimization. Yanping Nora Soong (talk) 12:03, 15 June 2016 (UTC)[reply]

It is not an NP complete problem to get *A* solution that meets your criteria. It is an NP complete problem to get the absolute optimal solution. Another way to word it: Can I find a path through a weighted network that is below a cutoff? Once I find one, I'm done. So, I use a greedy algorithm to brute force it. I know that I will likely miss complicated paths that are the absolute best, but I will get one that works. 199.15.144.250 (talk) 15:05, 15 June 2016 (UTC)[reply]
Updating the previous comment... If you can represent all options as a weighted graph, you can use Dijkstra's algorithm to quickly find an optimal solution. So, the trick is in the representation of the problem. If it is represented as "how do I pack all these options into a confined space", it is much harder to solve. If it is represented as "I have a network of locations with a weight to get from one to another and I want the shortest/cheapest/quickest route from one location to another", it is easy to solve. 199.15.144.250 (talk) 17:11, 15 June 2016 (UTC)[reply]
"Would Uber be really mad...?" MAYBE. I wouldn't like that, but I also don't like Uber, so maybe they'll like it. My point is we can't answer this. I can point you to their TOS for the API: [5], but interpreting that for your specific use case would constitute legal advice. Maybe call them if you want clarification. Seems to me you'd be aggregating Uber data with the competing subway, but maybe not. SemanticMantis (talk) 14:00, 16 June 2016 (UTC)[reply]

@Dismas: Square brackets are used for shortcodes (e.g. in WordPress). In this case it means that the website uses the Safer Email Link plugin for WordPress. Go here and scroll down to the "Safer Email Link Plugin" header. If you want the technical details you can read this and/or download the plugin and read the code (which is pretty much the same as the code in the "Examples" section of the Wordpress Codex).

@Dismas: I am not 100% sure, but I think that the most likely scenario is that a n00bish user used the WYSIWYG editor instead of the code editor.
  1. The user creates a mailto: link to TownClerk@foo.com like this
    <a href="mailto:TownClerk@foo.com">TownClerk@foo.com</a>
    
  2. Some time later someone (maybe the same person) realizes that the mailaddress has changed or is wrong and thinks that using spam protection may be a good idea.
  3. The user tries to fix the mailto: link in the WYSIWYG editor (by selecting the text and replacing it with the shortcode) but doesn't realise that this replaces the contents of the <A> tag with the shortcode without removing the old mailto: link that surrounds it. If xe tests it xe will not notice it, because the shortcode is replaced by another mailto: link, which means that the user sees the behaviour the user expects. Nesting mailto: links doesn't send mails to multiple users (for obvious reasons), the correct way to do that is:
<a href='mailto:person1@domain.com,person2@domain.com'>Email Us</a>

Suitable Unicode (UTF-8) characters for marking start and end of bold, italic, underscore, strikethrough, subscript and superscript ?

In a humanly readable plain text file (.txt), containing (UTF-8) text in various European languages, I want to use single character designated Unicode characters to mark the start and end of bold-, italic-, underscore-, strikethrough, subscript- and superscript- text.
Of course one could use plain wiki-markup (<b>bold-</b>, <i>italic-</i>, <u>underscore-</u>, <s>strikethrough</s>, <sub>subscript-</sub> and <sup>superscript-</sup> text.) , but I am looking for a single character solution (instead of the three, as in: “<u>” and six, as in: “</sub>”) that would be less obtrusively distracting, regarding the readability and comprehension of the text, while still clearly visible and just as intuitively understandable as the wiki-markup-solution.
So, what single Unicode characters might be best suited for this task?
--Seren-dipper (talk) 14:22, 16 June 2016 (UTC)[reply]

You can use some simple ASCII characters for some of this - Markdown does all four, with markup that's still readable when looked at plain - see markdown cheatsheet. Some email clients (I know at least Thunderbird) implements some of this (Thunderbird supports * for bold, / for italics, and _ for underscored, but I don't know of a sequence for strikethrough). -- Finlay McWalter··–·Talk 14:38, 16 June 2016 (UTC)[reply]
In many cases the * _ / # ~ ^ (and the other ordinary keyboard characters) will do fine, but, unfortunately, these also very frequently appear as part of the body text (in the texts that I want to mark). Therefore I need some other Unicode characters which preferably also hints or indicates the meaning. (Besides I would strongly prefer, but do not absolutely need, to have different characters for «Start of…» and «End of…»).
--Seren-dipper (talk) 15:30, 16 June 2016 (UTC)[reply]
Your example is not "wiki-markup", it is HTML (except the strike tag, which is actually strike, not s). The "ML" in HTML stands for "Markup Language". You are basically trying to invent your own markup language. As mentioned above, * is often used for bold, / for italic, _ for underline, and - for strike. The entire point is to embed markup in the content. No matter what you do, someone will say it looks like gobblygook. Then, you need to expand on your new markup language as people find problems, such as what I need to do if I want to show an equation like 10*3*5=150 and I don't want the 3 to be bold. If you strongly insist on writing an entirely new markup language, go ahead. Just be certain that you understand what you are doing. 199.15.144.250 (talk) 16:44, 16 June 2016 (UTC)[reply]

"Your PC ran into a problem and needs to restart"

This message has appeared on two computers running Win 10. Blue screen with a big :( In the one case, the computer actually restarted and all was well. In the other, the counter remained at 0% and I had to turn it off physically. Then it worked OK.

Is it really Win 10 doing this or something else? --Halcatalyst (talk) 15:09, 16 June 2016 (UTC)[reply]

Well, Win10 is restarting the computer, that is true. But the problem may be caused by something other than Win10. I hate vacuumcleaning with the burning passion of a thousand suns so most of the problems with my computers are caused by dust. There are a couple of options:
  1. if this happened only once, or very rarely, then you can probably ignore it (it probably won't be worth the time and effort to investigate why it happened).
  2. if this happens often enough to bother you then you can check what caused the error. Usually the error message displayed under the big :( gives an indication what may be wrong. If you are too late and the computer has already restarted before you can read what it says (or better yet, take a photo) then you can find the error by following these instructions. Once you know what the error message says you can post it here and people will probably be able to help you.
  3. if this happens often and your pc is very dusty then it may be a good idea to ask your local computershop to clean it, or ask a local nerd to get it cleaned. Always ask what it costs first, if it is expensive then politely refuse.
