These are not "Power saving features" but rather the toggles to disable your WiFi/Bluetooth adapters. The text is simply giving you a tip suggesting that you disable your WiFi/Bluetooth adapters to save power when you are not using them. There is an answer on Ask Ubuntu in regards to keeping network adapters active during suspend: <

Multibyte characters in URL are not rendering I have a bugging problem. For a website I made there are search engine friendly URL's generated. The only problem is there are ß-chars in the url too. Chars like ö, ï, ä, ü etc. are placed correct. But with the ß-char there is a diamond-icon with a questionmark in it. -> I thought it had to do with the charset which is used but i've tried both UTF-8 and iso-8859-1. Both without luck. I need to have the correct character in the url for the readability of deeplinks.

Thanks for your answers, both + 1. I've solved the problem by using the `iconv` function, which is installed by default.

fputcsv() add quotes to every entry?

Healpy default format for lmax I found in the Healpy documentation that `healpy.anafast` has a default value for lmax of 3*nside-1 Is there a reason for this standard? Is it a standard within HEALPix, a standard for CMB experiments, or may it has physical reasons? Edited: When I run `anafast` on a sky map `Nside=4`, the number of Cl values I get is of length = 12. That makes me think that lmax should be `lmax=3Nside`. However, when using generated Cl values, the first two numbers are equal to zero: the monopole is zero, the dipole is zero. Therefore, when I set the l values by `np.arange(len(Clvalues))`, should I also remove the terms `[0,1]` for the monopole and dipole?

Spherical harmonics discretized using HEALPix (either sampled at pixel centers, or avaraged over pixel areas) form a linearly independent system up to lmax = 3 nsmax -1. (from here: HEALPX anafast)

how can I see the differences in a designated file between a local branch and a remote branch? How can I see the differences in a designated file between a local branch and a remote branch? I know this command: git diff <local branch> <remote-tracking branch> But it gives the differences in all files between two branches while I only care about changes of one single designated file.

Take a look at `git diff --help`, which shows you: git diff [options] <commit> <commit> [--] [<path>...] So, you're almost there. Instead of: git diff <local branch> <remote-tracking branch> You can use: git diff <local branch> <remote-tracking branch> path/to/file

Two random numbers from different intervals: compute $P(b \leq a)$ You are given two random natural numbers $a$ and $b$: * $a$ is chosen from $[1, m]$ interval * $b$ is chosen from $[3, m+3]$ interval I need to compute probability of $b \leq a$ case. Assume $m > 1$. * * * There are $m$ different numbers in the interval $a$ is chosen from, and there are $m + 1$ numbers in the second interval that $b$ is chosen from. The solution from my notes from half a year ago: $$P(b \leq a) = \underbrace{\sum_{i = 1}^{m - 2} \frac{1}{m+2}\frac{i}{m}}_{\text{confusing part}} = \frac{1}{m(m+2)}\sum_{i=1}^{m-2} i = \frac{(m-1)(m-2)}{2m(m+2)}$$ I don't understand presented solution. Not sure where the 'confusing part' came from. Would anyone be able to show me how the thinking process looks like in solving such a task?

My result does not match the official solution. Consider each of the possible values for $b$ which are $≤m$. We have $\\{3,4,\cdots, m\\}$ so there are $m-2$ of them. Each of these has probability $\frac 1{m+1}$ of being chosen (since there are $m+1$ possible values of $b$ with no restrictions). For each choice of $b≤m$ there are $m-b+1$ choices of $a$ that are $≥b$. Each of those can be chosen with probability $\frac 1m$. Thus the answer is $$\sum_{b=3}^{m}\frac 1{m+1}\times \frac 1m\times (m-b+1)=\frac {(m-2)(m-1)}{2m(m+1)}$$ To check, consider the case $m=3$. For that case we have $$a\in \\{1,2,3\\}\quad \&\quad b\in \\{3,4,5,6\\}$$ The only winning case is $a=b=3$ which has probability $\frac 1{12}$. The formula I wrote gives that value, the official solution does not.

`user.name` in your .gitconfig is only for authorship of commits, and not used for authentication. It seems you are using password authentication before pushing to github.

Is there a command to move up and down the sidebar file list in sublime text? I use the sidebar a lot in sublime text and I want some quick way of moving up and down the list ( preferably with a keybinding but if there is some command then I'm sure I can bind it). For instance if I have 10 files in a folder then I can click on one and view it, but then I have to pick up the mouse to view the next or previous file. I want to be able to move to the next or previous file in the list. I know I can use ctrl-p to search for the file but I was hoping to have a keyboard shortcut to simply move to the next file. Is there anything like this?

If you focus the sidebar with `Control+0` you can use the arrow keys to move up and down through the files. `Right Arrow` will open a folder and `Left Arrow` will close it.

Reflect a letter horizontally using CSS I know how to reflect single letters vertically using `transform: rotate();` but not how to reflect them horizontally.

I want to use it with the selector `.logo:first-letter {}` for my logo. <a href="#" class="logo">RR</a> EDIT: < Cant use Я because I'm using a font from google which doesn't support it.

Set the `scaleX` property as a transform. .logo:first-letter { transform: scaleX(-1); } If it's always a specific letter, it might be a better idea to just use unicode for this. In your case, `CYRILLIC CAPITAL LETTER YA` (Я) will work.

Is a multi-column index generally worth it if the second column will always only have a few entries long for each entry in the first column? If I have two columns in a table, and I plan to do lots of queries on those two columns (which would normally suggest creating a multi-column index), but I also know that each unique value in the first column will only have around 3 to 5 values in the second column, is the multi-column index still worth it vs. just having an index on the first column? Assume I don't care about the cost of creating the index, I'm strictly interested in the extent to which the multi-column index will increase the query speed over an index for just the first column.

The issue is whether the multi-column index can cover the query or at least the `where` clause (assuming your queries are referring to filtering in the `where` clause). In general, the answer is yes. Consider data that looks like this: x y datapage a 1 datapage_1 a 2 datapage_2 a 3 datapage_3 b 1 datapage_4 . . . If your query is: select x, y from t where x = 'a' and y = 2; Then, with no index, the database has to scan all data pages to find matching rows. With an index only on `x`, the database can find all the "a" values, but it still has to load three data pages to get the `y` values. With an index on both `x` and `y`, the database can directly go to "datapage_2".

Best way to clean moldy fermentation bucket I've just had a major house move. During the move, I noticed my fermentation bucket had developed mold. Quite large mounds (to me anyway) of perhaps 0.25in diameter, in the corner of the base. Clearly I didn't do a good job of cleaning it last time I used it. So far I've only rinsed with high pressure water - basically to remove the odour for the move. How should I best kill and clean this stuff ready for brewing? Is regular StarSan sufficient? Of course chlorine bleach would really clean it but it would leave a bad taste. Perhaps something else? Or perhaps I should just replace the bucket at chalk it up to "remember to clean the bucket properly".

StarSan is a sanitizer, not a cleaner. I'd use Craftmeister alkaline cleaner. Amazing stuff and makes PBW look weak. Or just buy a new bucket.

Display query string in asp.net controls I'm writing an ASP web application with VB back-end. What I'd like to do is generate a url and display this in control on the page. For example if I have a label and a button on the form. The label is blank. When the button is clicked the following code fires: Protected Sub btnGenerate_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnGenerate.Click label1.Text = "Hello" End Sub What I'd like to have is a url that would point to my ASP Page with the words "Hello" in the label. Is this possible?

Pass the text in query string e.g. suppose relative path of the page is /pagename.aspx , you can pass the query string as per given example below: /pagename.aspx?text=hello in c# write following code in Page_Load event //You don't have to check the url all the time , so just check it if page is not posting back (first time after user visits the page and ignore all other same page post backs. Label can maintain its control state (text value) after every postback, so assign it only once to increase performance if (!IsPostBack) { //Check if query string is provided or not , if it is not provided take some default text, I am taking empty string as default text. string givenText = (Request.QueryString["text"] == null)?"":Request.QueryString["text"]; label1.Text = givenText; } You can also create a property for text given through query string and default text.

Defining a C# Method Body at runtime (dynamically) I have a base class that defines (among others) a certain empty virtual method (used as an event handler). Up to now, all instances are created from a derived type, which overrides the virtual method to fill it with life. This type is generated dynamically and does all it should, but I really wonder whether Reflection (.Emit) or whatever levers the .Net framework has to offer make it possible to just modify the body of the abovementioned method. Any ideas? Thanks in advance!

You could make the body call a delegate and then change the delegate instead of making the method virtual and overriding it. And if the only use of that method is as event handler, why make it a method at all? Just assign the generated function directly to the eventhandler. You can construct an Expression Tree and then compile it into a delegate which you can then assign to the eventhandler.

You need to add constraints to your hello world label. You can add constraints to a view by selecting it and pressing on one of the constraint buttons on the bottom right side of the view editor. Currently, it sounds like your label is displaying off screen.

Which design should be used in this scenario? I have a business logic like below and I would like to know which design pattern should be used here. Basically I have an input and number of factories which creates objects which are derived from the same base class. Input => factory1 => Output1 Input => factory2 => Output2 Input => factoty3 => Output3 ........ ........ The number of factories varies. This is the kind of logic which will be enclosed in a method which will create a collection of Output1, Output2... and returns it. Which is the right design pattern in this scenario ? Another most matching real time example.. I have a filename/pattern and there are different Finders. One for finding the word docs matching the pattern, one for finding the excel docs. one for finding the ppt docs matching the pattern. At the end all docs(word,xl,ppts) should be returned.

It seems fairly simple as I see it and you may not need a design pattern. Lets call this object a Processor instead of Factory so as not to confuse with the Factory pattern. So your code could be simply like this : interface Input; interface Output; interface Processor { Output process (Input i); } MainClass { List<Processor> processors = initializeProcessors(); List<Output> process(Input i) { List<Output> outputs = ...; foreach (Processor p in processors) { Output o = p.process(i); outputs.add(o); } return outputs; } }

Grails: how to set data binding to use load method instead of get one? If i have a form such as bellow <input type="text" name="someCollection[0].someAssociation.id"/> <input type="text" name="someCollection[1].someAssociation.id"/> <input type="text" name="someCollection[2].someAssociation.id"/> Because Grails provides automatic data binding when it encounters a _.id_ suffix, it seems Grails uses _get_ method instead of _load_ one which implies 3 queries as follows SELECT * FROM SomeAssociationClass WHERE id = ? SELECT * FROM SomeAssociationClass WHERE id = ? SELECT * FROM SomeAssociationClass WHERE id = ? I just need _load_ method because it does not hit the database unless you use other than getId() (NOT APPLIED). So, how can i customize data binding so that it uses load method ?

To avoid loading an instance of the database, we need to remove the _.id_ suffix and register a custom propertyEditor which takes care of invoking _load_ method class AppPropertyEditorRegistrar implements PropertyEditorRegistrar { void registerCustomEditors(PropertyEditorRegistry registry) { registry.registerCustomEditor(Question, new PropertyEditorSupport() { @Override void setAsText(String value) { setValue(Question.load(value as Long)) } }) } }

In constract to e.g. `Assert.False` where I can supply a message to be displayed when the assert fails, e.g. `Assert.NotNull` has only one overload that just takes the object to check. Is there a reason for it? namespace Xunit { public class Assert { // ... public static void False(bool condition, string userMessage); // ... public static void NotNull(object @object); // ... } }

Dogma. They believe that you should never have more than one assertion per test, thus you don't need it.

It is separate from everything else specifically so that you can tailor it to your needs. * * * Here is my version of said library with messages added: <

Tidally locked, and yet spinning? Reading about Uranus almost 90° tilt, I was wondering if some rocky planet with mass concentration at one pole could possibly spin around its own axis, while still being locked to its star? Which means the more massive pole always points toward the star?

I think what you are envisioning is having one pole always pointed towards the primary star. So the planet would rotate about that pole, but then the direction of the pole would change over the course of a year to keep the pole pointing towards a star. This phenomenon of the direction of the pole changing is called "precession". The Earth does it over a period of 26,000 years, but the pole only traces out a fairly small circle in the sky, rather than twisting about a perpendicular line like you envision. I think your scenario is improbable at best. Planets are like gyroscopes and resist having their axes of rotation be twisted about a perpendicular axis like that. Even a planet with mass concentrations at both poles (maybe a long cigar shape) to maximize tidal force would probably end up losing the perpendicular rotation to tidal friction, and just end up rotating slowly about an axis nearly parallel to the axis of the orbit.

Animating background color of border in Silverlight, State precedence in VisualStateGroups This is a silverlight/XAML question. Not sure what I'm doing wrong, this seems to throw an error: <ColorAnimation Storyboard.TargetName="btnRemoveBorder" Storyboard.TargetProperty="Background" To="#FFDEBA29" Duration="0" /> 2nd question is... rather confused with the Selected and Focused states. Can one state take precedence over another?

Background is not a Color but instead a Brush which is why it can't be animated directly with a ColorAnimation. Instead try the following. <ColorAnimation Storyboard.TargetName="btnRemoveBorder" Storyboard.TargetProperty="(Border.Background).(SolidColorBrush.Color)" To="#FFDEBA29" Duration="0" /> With regard to the VisualStateManager question, one state from each state group can be active. So in the case of a Button for example, it can be in both the Focused and Pressed state. For this reason, you should try to design your states and control templates in such a way that does not depend on which state becomes active first. Usually this means you shouldn't animate the same element/property in two different state groups. But technically speaking, there's nothing preventing you from doing so. Whichever state the control goes to last (using the VisualStateManager.GoToState method) will take precedence.

However: \- creating a database object inheriting from QThread doesn't seem to be a natural design (what would run() be? ) \- I assume I would need to use signals and slots for UI / core interaction; yet this feature seem to be relatively recent in Qt, so I'm wondering if my "design" is wrong. \- QObject descendants are apparently designed to live in the thread in which they were created, so I'm concerned the communication of models (from the database thread) to the UI thread will be problematic. Thanks for your comments.

You might consider using QtConcurrent::run(). You'll pass in the function you want. It'll spool off a thread to run the function and give you a QFuture that you can use to get the eventual result. You could poll the QFuture to see if it `isFinished()`. Better, however, may be to use QFutureWatcher which watches the QFuture for you and emits a signal when it's done. See the example code blurb in QFutureWatcher.

which are the correct answers? let$\\{a_n\\}_{n ≥ 1}$ be a sequence of positive numbers such that $$a_1 >a_2>a_3>...$$ then which of the following are always true ? 1. $\lim_{n \to \infty}a_n=0$ 2. $\lim_{n \to \infty}\frac{a_n}{n}=0$ 3. $\sum_{n=1}^{\infty}\frac{a_n}{n}$ converges 4. $\sum_{n=1}^{\infty}\frac{a_n}{n^2}$ converges I suppose all answers are true. Then am I right?

1. False. Take $a_n=\frac{1}{n}+1\xrightarrow[n\to\infty]{} 1$. 2. True. $0< \frac{a_n}{n} < \frac{a_1}{n} \xrightarrow[n\to\infty]{} 0$ (as $a_1$ is just a constant). 3. False. Take $a_n=\frac{1}{\ln n}$. 4. True. By comparison: $0< \frac{a_n}{n^2} < \frac{a_1}{n^2}$, and the series $\sum_{n=1}^\infty\frac{1}{n^2}$ converges.

Heroku cron job help How do I run the task reklamer:runall every 15 minutes in cron.rake? I have my cron.rake file: desc "This task is called by the Heroku cron add-on" task :cron => :environment do if Time.now.hour % 4 == 0 # run every four hours puts "Updating feed..." NewsFeed.update puts "done." end

Heroku only provides daily or hourly cron jobs so I think you're out of luck with running cron jobs every 15 minutes. Instead, you could use delayed_job to run jobs every 15 minutes. At the end of each run, your job code should create another job which will run in 15 minutes. You could calculate 15 minutes from the start or the end of the job, depending on your needs.

Why does Microsoft Excel change the characters that I copy into it? I live in Spain and I am using the English version of Microsoft Excel installed with wine on Ubuntu. The problem is that I use my laptop at work and when I copy text into excel (text that is Spanish) the characters that are Spanish (such as é,ñ, á...etc) are changed into weird characters. How can I sort this out? For example: Martínez José....appears as "Martínez José" in my spreadsheet and I really cant have it this way or my boss will kill me. :)

This is an encoding problem anyway it may be hard to solve this issue for you. But you can use **Libreoffice Calc** it looks like **Microsoft office excel** and also you can save in **Microsoft office** formats(xls-xlsx)

Is it a bad practice to do redirections out of controller classes? I'm basically attaching a listener to an event that's triggered when a controller action completes. Said listener has a dependency that calls a 3rd party API client and do some action. I.e: creates a new document in google drive). Following the example, if the user hasn't authorized through OAuth2, the system should redirect to the OAuth page. This action would be done by the listener. Is this a bad design?

You risk needing to attach many many listeners for this authorization concern. Ideally you would make it cross cutting, something that gets check before the controller creating the google drive document gets invoked. If your framework does no provide any means to do this then I would explicitly add 'am I authorized to do this?' invocations at the controller and not use listeners. When not authorized, the controller can error out with 'not authorized' which can be caught globally somehow to trigger the redirect.

Convert int days to months and days using joda Say I have 203 days. I want to convert that number to the string `x months y days` from today. How do I do that using joda time? (of course 203 is just an example, use z if that helps.)

EDIT: Working out the period _starting at a particular date_ is pretty easy with Joda Time. For example: public Period getMonthsAndDays(int days, LocalDate start) { LocalDate end = start.plusDays(days); return new Period(start, end, PeriodType.yearMonthDay().withYearsRemoved()); } You can then call `Period.getDays()` and `Period.getMonths()`. Just pass in today's date in the relevant time zone (which you need to consider) and you're away.

List<> remove item issue We are using `List<object>` type as datasource for dropdownlist. Process flow: 1. Assign value (`List<object>`) to the session in the pageload event(`!ispostback`). 2. Retrieve value from session in `ddl_SelectedIndexChanged` event 3. Remove a particular item from the list and bind to the ddl Code: List<Loc> locList = new List<Loc>(); locList = (List<Loc>)Session["Loc"]; locID = "xxx"; locList.RemoveAt(locList.FindIndex(FindLocation)); Problem: Item is getting removed from the base source also (session).

The problem is that you're manipulating the list that is stored in the session, not a copy. Instead, if you do something like this: List<Loc> locList = new List<Loc>((List<Loc>)Session["Loc"]); locID = "xxx"; locList.RemoveAt(locList.FindIndex(FindLocation)); you're operating on a copy of the list, and the original won't change.

Is an eigen recognition model picklable? I have a python-based face recognition script running several processes (threads?) all doing different things. I am attempting to use one of these to re-train the model once the training images have been changed/updated. I have tried sending the model through the python pipe function: pipe.send(model) I am not hit with any exceptions, it just hangs there indefinitely. I fear that either the model is either unpicklable, or simply just too big!

`multiprocessing` uses `pickle` (or `cPickle`, depending on the version). Have you tried checking like this? >>> import pickle >>> pik = pickle.dumps(model) >>> _model = pickle.loads(pik) If that succeeds, it's serializable by `pickle`. If it's not, you might try using a more powerful serializer, and a fork of `multiprocessing` that utilizes said better serializer (i.e. `dill` and `pathos.multiprocessing`).

Is it possible to check if pdostatement::fetch() has results without iterating through a row? I have a page which needs to check for results, and the way I came up with to do it is successful, but iterates through the first row of results. Is there a way I can check without iterating, or to go back to that first row without executing the query again? I was doing this: $q = pdo::prepare($SQL); $q->execute(array(':foo'=> foo, 'bar'=>bar); if(!q->fetch){ //no results; }else{ //results; }; It does pretty much exactly what I hoped, with the unfortunate side affect of skipping the first row of results. I've resorted to running $q->execute() a second time. Is there a way to avoid doing this?

Just put the result of fetch into a variable: if($row = $q->fetch()) { // $row contains first fetched row echo $row['coloumn_name']; } else // no results

How to make a button in Xcode that globally stops AVAudioPlayer? I'm trying to make a tableviewcell stop all sounds in the app when it is clicked. I know how to stop sounds with `soundEffect.stop() soundEffect.currentTime = 0`, but I don't know how to apply this to a cell and this doesn't work if the StopSound button is on another viewController with a different class. How do I make a function that globally stops AVAudioPlayer and apply that to a cell?

The problem is that the player is not alone. Try this. To stop AVAudioPlayer on another ViewController you may use NotificationCenter. Example... First time, add function at VC, where you need to stop AVAudioPlayer. @objc func stopAVonThisVC() { AVaudioPlayer.stop() } Second, add NotificationCenter observer at this VC, and after just post on tap button. // At VC, where you need to stop AVAudioPlayer. NotificationCenter.default.addObserver(self, selector: #selector(stopAVonThisVC), name: NSNotification.Name("Stop at VC1"), object: nil) // At VC2 NotificationCenter.default.post(name: NSNotification.Name("Stop at VC1"), object: nil) Sorry for poor english.

How I can get an Android phone to vibrate while shaking it?

Will this work out doing it this way? I am unable to test it as I don't own an Android phone, so I am asking (programming-wise) if this is possible.

Yes, it will work that way. Just make sure to stop handling the sensor events for the 500 milliseconds the phone is vibrating. boolean isVibrating = false; Handler handler = new Handler(Looper.getMainLooper()); if(!isVibrating){ if(event.values[0] > 1.0) { vibrate(500); } else if(event.values[1] > 1.0){ vibrate(500); } } void vibrate(long time){ isVibrating = true; vibrator.vibrate(time); handler.postDelayed(new Runnable(){ public void run(){ isVibrating = false; } }, time) }

Using these classes, I filled in data in an object and marshalled it to get an XML file. But the XML elements in this marshalled file is not having the prefix "abc".

The name of the prefix is meaningless. All it does is make a connection between a namespace and the tags that belong to that namespace. Whether the prefix is _abc_ or _namespace01_ or there is no prefix because the default namespace is used doesn't matter. As far as I know you can't force the usage of a prefix or the specific name of a prefix in JAXB.

Yea so like they said pivot tables. To get your results, I had to do it using CONCATENATE function. There might be a better way. But this is how I did it: first do a CONCATENATE column: !CONATENATE COLUMN Then insert your pivot table and select the right options: !PIVOT TABLE Then de-concatenate your School_id and Year !De-Concatenate 1 !De-Concatenate 2 Like I said there might be a better way to do this - but then you would just need to organize your headers the way you want them and you should have what you are looking for.

Again a question related to uncorrelatedness and independence. Consider a random vector $\mathbf{Z}$ of length $N$ whose elements are i.i.d. and zero-mean. We construct two new scalar random variable $X$ and $Y$ from $\mathbf{Z}$ as follows: $X = \langle\mathbf{a}, \mathbf{Z}\rangle = \mathbf{a}^T\mathbf{Z}$ and $Y = \langle\mathbf{b}, \mathbf{Z}\rangle = \mathbf{b}^T\mathbf{Z}$ where $\langle,\rangle$ indicates the inner product, and $\mathbf{a}$ and $\mathbf{b}$ are deterministic and orthogonal vectors, i.e., $\langle\mathbf{a},\mathbf{b}\rangle=0$. One can easily show $X$ and $Y$ are uncorrelated, my question is we can generally show that $X$ and $Y$ are also independent!!! I mean that for the case that $\mathbf{Z}$ follows jointly Gaussian distribution, $X$ and $Y$ are independent but what about other distributions!!! Best, Farzad

OK, I respond because I need some reputation points... Counterexample: $N = 2$, $a = (1,1)$, $b = (1,-1)$. Entries of $Z$ are iid uniform on {$-1,1$}. Then $X = 2$ implies $Y = 0$, such that the variables are not independent.

Can I restore a game from Mac to PC using steam backup/restore or by copying? I have CSGO installed in my MacBook and I don't want to re-download at least the whole file. So I was thinking if it is possible to create a steam backup on my MacBook and restore the file on steam PC or by copying files from PC? Is it possible for at least some file?

Unfortunately the short answer is **NO** and **NO**. In theory it's possible to reuse part of the files (textures, audios, etc), because this ones are common between the platforms, however the binaries are completely different and due the steam method of backup (the whole thing in one file) the hash will be different. it's more or less as you try to run a PS4 game into an XBOX. You may be able to transfer the save games between platforms. But I don't think is the case of CSGO.

Why do I see plaintext credentials in wireshark using basic auth over http? I am using Wireshark to analyse network traffic and basic auth on a local server which I set up in my network. When authenticating with basic auth I can see the passwort and username in the "Authorization" header of my http request in Wireshark. I know that it is not secure to use basic auth over http (and maybe not even over https) but since the credentials get base64 encoded I did not expect to see them in plaintext. Does wireshark automatically decode the base64 encoding on the credentials or did I get something wrong with how the encoding process works?

Your assumption is correct, Wireshark has decoded the Authorization header for you. You should see both the base64 string, and the decoded results. Wireshark does more than just show raw packets, it dissects them. That's what makes the tool so convenient and powerful (or scary from a point of view).

Is there anything I can do to fix/help this besides upgrading my equipment?

From the comments, it seems like this is your problem — you're probably focusing _past_ infinity. See Why do some lenses focus past infinity?

Los `join`s se utilizan cuando quieres obtener resultados de varias tablas y trabajar con los datos como si fuse una única tabla. En este caso quieres obtener un contenido (que esté en dos categorías), por lo que yo haría: SELECT * FROM contenidos WHERE contenidos.id IN ( SELECT idContenido FROM contenido_x_categorias WHERE contenido_x_categorias.idCategoria = $idCategoria1 ) AND contenidos.id IN ( SELECT idContenido FROM contenido_x_categorias WHERE contenido_x_categorias.idCategoria = $idCategoria2 ) Es posible que esta sentencia SQL se pueda optimizar. Si no tienes muchos cambios en las tablas, puedes cachear en PHP los listados de ID de producto por categoría, y así te evitas esas dos consultas extra.

`print` can print a `float` if it's passed to it, that's not the issue. The issue is, as the error message says, there's no `+` operator between a `float` and a `str`. One way to work around this is to explicitly convert the `float` to a string: print(str(round(e1*e2,1)) + word) # Here^

The Sponsor Eagle randomly decides what prize you get, although Bux are rare and only appear about once a day. However, the ability to watch an AD to increase how much you get is determined by both the size of the reward compared to your Level, and how many times you've watched an AD to increase it.

Total sql connection consuming by application I have multiple C# applications and all applications use the same database(SQL server 2014) and same credentials(Same connection string). All application run on the same server. Now, my question is anyhow can I get the total number of SQL connections consuming(current open connection) by particular application right now? I.e 1. 3 connections open in Application1 2. 2 connections open in Application2 I tried using "App Name" in connection string but I don't know how to get total connection consuming by "App Name"?

Enumeration Type-Safety in D What is the state and plans on type-safety of enums in D? I expected import std.stdio: writeln; void main(string args[]) { enum E {x, y, z} E e; writeln(e); e = cast(E)3; writeln(e); } to fail to compile because of D's otherwise strong static type/range checking or at least give an RangeException when run. To my surprise, it instead prints cast(E)3 Is this really the preferred default behaviour for the majority of use cases? If so have anybody written some wrapper type providing more stricter range-checking preferrably in compile-time?

`cast` means you're taking matters into your own hands, and you can do anything with it - useful, like ratchet freak said, for combining flags. (Though, in those cases, I like to give an exact type and explicit values to each item to be sure everything does what I want, so enum : ubyte { x = 1, y = 2, z = 4}, that kind of thing) Anyway, there is a way to get runtime exceptions though in a case like this: use std.conv.to: import std.conv; import std.stdio; void main() { enum E {x, y, z} E e; writeln(e); e = to!E(2); // gives z, whereas to!E(3) throws an exception writeln(e); } Cool fact: to!E(string) also works. to!E("x") == E.x, and to!string(E.x) == "x".

The code is required to make a random number then keepon spouting random numbers until it reaches that number, but its always the same Here's the idea of the code: The code is required to make a random number then keepon spouting random numbers until it reaches that number, but its always the same. heres the code: #include <stdio.h> #include <math.h> int rdt () { long long int randomonium; randomonium=rand(); return randomonium; } int main (){ int rd; int no; while(1){ rd=rand(); printf("%d\n", rd); if (rd== rdt()){ break; } } return 0; }

You can put a `srand(time(NULL));` just before the `while` to change the random seed used by `rand()`. Don't forget to include `time.h` in the code.

Memory leaks in an iPhone app I have the following memory leaks in my code. What does it mean? How can I fix this? #import <UIKit/UIKit.h> int main(int argc, char *argv[]) { NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init]; **int retVal = UIApplicationMain(argc, argv, nil, nil);** [pool release]; return retVal; } Thanks in Advance.

That code is from your main.m file. It seems odd that this part of your code would leak, if at all?? How did you find this leak? Are you using the simulator or a real device? If using the simulator you can sometimes have leaks that are not leaks at all, it is always better to test these kinds of things on a real device (which you have not specified). Double check all of your release, retains etc in your code. You might just spot something you have not released. (in xcode 4 use the assistant editor I find it better to spot these kinds of things alt+cmd+enter). Your question otherwise is hard to answer, you might want to edit it with how you found it and in what environment. Hope some of this helps [EDIT] saw you tagged this with cocos2D (what version are you using of that?) there are some reported issues elsewhere on SO with memory leaks using older versions of cocos2D

Graph theory question, Java. Which algorithm to achieve the following I have a graph, with X nodes and Y edges. Weighted edges. The point is to start at one node, and stop at another. Now here comes the problem; Visualize the problem. The edges are roads, and the edge weights are the max weight limits for vehicles driving on the roads. We would like to drive the biggest truck possible from A to B. So the maximum allowed weight for a truck taking a given path is the smallest weight of all of the edges in that path. I want the largest maximum allowed weight for all paths from A to B. Can I use some sort of Dijkstra's algorithm for this problem? I'm not sure how to express this problem in the form of an algorithm that I can implement. Any help is much appreciated. **Update:** I tested out somethings that didn't work for me. A node would have to have one max truck for every incoming edge.

Dijkstra's algorithm should work, but your "distance" in this case is a bit weird. Your "distance" is the maximum sized truck you can get to a node. Let's call that M[v] for a node v. You need to process nodes in order from largest M[v] to smallest M[v] (opposite of normal Dijkstra), and calculate for each edge e from v to w: M[w] = max(M[w], min(e.weight, M[v]))

Segmentation Fault when calling free() I'm building some modular function and I'm not getting why I get a segmentation fault after freeing my module. **My .h file** void StringInit(String *this, char const *s) { this->str = strdup(s); printf("%s\n", this->str); } void StringDestroy(String *this) { if(this == NULL || this->str == NULL) return; this->str = NULL; free(this); } int main() { char *str; String test; str = "hello\n"; StringInit(&test, str); StringDestroy(&test); return(0); }

`free` should be used to free pointers that have been allocated using `malloc`. Your `test` string has been allocated on the _stack_. As Alfe points out: String* test = (String*)malloc(sizeof(String)); StringInit(test, str); StringDestroy(test); And as Adriano's answer points out, you've also allocated a new string with `strdup`. Seems like there are a myriad of issues here!

CGRectFromString() for general structs @"{0, 1.0, 0, 1.0}" I wish to convert the above string to a struct like this: struct MyVector4 { CGFloat one; CGFloat two; CGFloat three; CGFloat four; }; typedef struct MyVector4 MyVector4; `CGRectFromString()` does the same thing, only for `CGRect`. How can I do it for my own structs?

If there is a function for rect it means that it is not working by default. You have to create your own function something like MyVector4FromString. You may like to to know that you can init struct object like this also. MyVector4 v1 = {1.1, 2.2, 3.3, 4.4}; This is a very easy C syntax. so I don't think you require to init from string. See here : 4.7 — Structs But if you are getting string from server or from other function than yes you have to create your function to do this. You can parse string and init 4 float value. This link will help you to divide string in multiple part : Split a String into an Array All the best.

VIM + ctags open too many annoying buffers I usually only works on two or three files at one time, so after mapping "Shift+H" to ":bn", I can quickly switch among these files by pressing "shift+H" several times (I don't have to use :ls plus :bn). But after jumping to/back the definitions of functions via ctags's ctrl+], it opens many buffers for new files (:ls now shows many buffers). Now as the number of opened buffers increases, it is slow to relocate to new files using "Shift+H"(:bn). Any ideas? Do you have these problems? Is it possible to hidden buffer caused by ctags or at least delete these ctags_caused buffers when code returning from jumping? Thanks. PS: I don't like the way of using :ls to see the file you want to jump, then using:bn to switch files, since I think pressing "shift+H" is more convenient and faster. Thanks. \---Peter

If you are using vim then using tabs instead of buffers may solve the problem. You can open the two or three files in separate tabs (:tabnew filename), and use the 'gT' and 'gt' normal commands to switch back and forth between the tabs. You can modify your "shift+H" mapping to either 'gT' or 'gt'. You can also use ctrl+w ctrl+] to jump to function definition in a new window so that you can close the new window and go back to your original window containing the buffer that you jumped from. Also related, when I have many buffers loaded I normally rely on the ":b" command completion's feature to quickly switch to the buffer that I want based on the partial filename that I give to it.

Compute $E(\sqrt{X+Y})$ given that $X,Y$ are iid Compute $E(\sqrt{X+Y})$ given that $X,Y$ are iid. Assume $X,Y$ are iid both having an Exp($\lambda=1)$ distribution. Although this is the only information provided in the question, I know that since they are independent, then the joint distribution must be $$f_{X,Y}(X,Y)=e^{-x} e^{-y}$$ Then we must integrate: $$\int_{0}^{\infty}\int_{0}^{\infty}e^{-x}e^{-y}(x+y)^{1/2}dxdy=\int_{0}^{\infty}e^{-y}\int_{0}^{\infty}e^{-x}(x+y)^{1/2}dxdy$$ This integral seems complicated to evaluate. I tried it out and it seems like I'll have to do parts atleast twice. Wolfram says the answer is $1.32934$ and I have $1.33$ as one of the options to this question. I want to know if there's an easier way to evaluate this. Do I even need the integral? Or perhaps is there some trick to get the answer with this integral?

One way of getting the integral slightly faster is to see that everything is in terms of $x+y$ only. So let $z=x+y$, which ranges from $0$ to $\infty$, and then given $z$ we have $x$ ranges from $0$ to $z$. The Jacobian for this is just $1$. Then the double integral becomes $$ \int_0^{\infty}\int_0^ze^{-z}z^{\frac{1}{2}}\,\mathrm{d}x\,\mathrm{d}z=\int_0^{\infty}e^{-z}z^{\frac{3}{2}}\,\mathrm{d}z=\Gamma\left(\frac{5}{2}\right)=\frac{3\sqrt{\pi}}{4}$$

So, to simplify and ilustrate. Lets say that I'm drawing rectangles on the screen. My rectangle has 20px/30px (sides). Do I draw the first one in (0,0). The next one could be (21,0), and the next one (0,31). So, if I slide the screen a bit to the side, how do can I make sure that I'll draw like a forth rectangle in (21,31) relative the way my screen was before. thank you so much!

You need to associate lat, longs with the corners of your rectangle if you want them to appear at a particular location. It might be easier to do this using Maps APIs Poly line.

Paypal Express Checkout capture large amounts (bigger than 10.000$) in many transactions we have integrated Paypal Express Checkout as payment method in a website. We have found out that there is a max amount of 10.000$ or 7000€ limit per transaction. Lucky we read it, because this limit is only in Live environment (in Sandbox there isn´t any limit and it´s working fine). In order to workaround this, what we are trying to do is: 1. Create a single authorization for total amount (i.e 19.000€). 2. Split the capture in many transactions of max. 6.000€ According to this we would have 3 transactions of 6.000€ and one more transaction of 1.000€. I don´t know if this is the right approach, anyway we capture the first transaction ok. However, we are getting an "Authorization has already been completed" Paypal error when trying to capture the second transaction. Do we need to send each capture with different transactionID? How should we do it?

What is the difference between getData('name') and getName() I am using magento 1.8 And I am facing problem when I use below methods $product->getData('name'); $product->getName(); Is they are same, I sure that they return same value[answer]. When I am using I am getting error Fatal error: Call to a member function getData() on a non-object in So may i know the exact difference between these two function. Thank You,

They may be the same or they may be different. It depends on the object you are using. If the class you instantiate contains the method `getName()` then the result you get from `getName` and `getData('name')` may be different. You can even get an error if the class does not extend `Varien_Object` and does not have the method `getData`. For classes that extend `Varien_Object` and do not contain the method `getName()` the results of the 2 methods are the same. `Varien_Object` implements the method `__call` that is called if a certain method does not exist. See here how the code looks like. So it basically maps the call of any method `getSomethingHere()` to `getData('something_here')`. It works the same for "fake" methods that start with `set`, `has` and `uns`. More details provided here.

Disable autoremove of old kernel versions on Fedora 37 Somewhy i can't boot on kernel version higher than 6.0.7-301 (more here). Recently Fedora automatically downloaded kernel 6.1.10, and after a few days 6.1.11. Both of them, as i said, i can't use for boot. In menu, where I select a kernel version, there is always a 3 options. Earlier, before kernel 6.1.10 and 6.1.11 was installed, i had 6.1.7 and 6.1.9, and now they are deleted. So, as i expect, after kernel 6.1.12 will be installed, 6.0.7 will be deleted automatically and i will have no opportunity to boot (if after release of 6.1.12 the problem will not be solved). Also, It will be useful for me to know what could I do if 6.0.7 will be anyway deleted.

Either lock the kernel, preventing updates (replace `6.0.7-301.fc30` with _your_ specific version, e.g. 6.0.7-301.fc37.x86_64): sudo dnf versionlock add kernel-6.0.7-301.fc37 Or disable kernel updates: sudo dnf update --exclude=kernel* That said, you might try to reinstall Fedora -- 37 seems to be the current version, at this time, and _should_ work with latest kernel. As for, "what could I do if 6.0.7 will be anyway deleted," **use dd to make a disk image**. You can can recover from almost _any_ new issue by restoring a recent image.

The version that it checked out for me is still behind `main/development` and has old code. What is going on here? I did `git fetch` and the `git pull`.

Whenever you need to restore one file, you might consider using the command `git restore` instead of the old and confusing `git checkout`. In your case: git fetch git restore -SW -s origin/main/development -- path/to/UsersTable.tsx That way, you don't pull, meaning do not merge `origin/main/development` to `chore/add-linting`, so you don't have any merge conflict to manager. You just restore one file content from a version of another branch.

Uploading photographs My question is regarding uploading photographs to a webserver. I recently observed while uploading a photograph on facebook that it can upload (and by default it does) upload smaller photographs than what we request. Now, I can think of uploading a full size photograph and compress when it reaches the server. But how could facebook resize the picture while uploading. `Is there any request header (I think there is not) that asks browser to upload specific size image and manipulate the exif/jpeg data in the file.` If not, some plugin/Flash/Javascript has to read the file/images from our system. `Does web standard really allow file reading from the user system?` Please advise. Regards, Mayank

Website / webserver cannot do anything with the image until it is uploaded and saved into target directory. It must receive fullsize image and then resite it to desired size [generate thumbnails, etc.]. There is no request header that you described. Web standards don't allow reading files from user hard disk. The thing that they allow is to select file from hard disk and then send to server - initiative is on the client's side, not server's. Is there anything more you would like to know? **update** See this: Flash upload image resize client side As I said - without external mechanisms we can't do anything. But of course, if we take into account Flash, Google Gears and so on, everything is possible.
