| UIImage(named: ) returns nil in cocoapod library on ios 12.4-5 Posted: 25 Sep 2021 08:12 AM PDT I have my Cocoapod library, In this library I access my images this way: let bundle = Bundle(identifier: "com.mylib.mylib") let image = UIImage(named: "image_name", in: bundle, compatibleWith: nil)
This works perfectly on devices 14.0 and above, but in IOS 12.4 this always returns the nil. I tried other way to get bundle like this: let bundle = Bundle(for: type(of: self)) result is same. Interesting is that when I import library in project, from library project (as source code), it works without problem (on 12.4). but when I try to import library from pod, it returns nil (only on 12.4). Also images from main bundle is not problem, it can display main bundle icons in my library. I'm out of ideas of what can be the case..  |
| MoveWindow does not scale the window when moving to a different screen Posted: 25 Sep 2021 08:12 AM PDT I have a Windows application with floating windows that I am running on a multi-monitor setup (FHD, 4K). The application is marked as system-aware, so we pick the current DPI value for the primary monitor and scale according to that. After that the OS bitmap-scales it. The application is running on Windows 10. Now when one of the floating window is dragged to another monitor then the OS bitmap scales it automatically an it all works fine. The problem is that we have some windows without a title bar and we have code to move those windows by dragging from the client area of the window. When the mouse is released, we call MoveWindow API to move the window to target location. This works fine on a single monitor but when we drop the window on a different monitor then it does not bitmap scale seems to lose its drop location. The OS only seems to bitmap-scale when we drag a window by its title bar and not when it is moved programmatically. Any ideas on how this automatic scaling can be achieved when moving a window programmatically?  |

So I have two tables, one is an inventory of products with their quantities for each size, and the other is purchase lines of products with the purchased quantities of each size. I want to calculate the final new inventory quantities of each size, zero-ing the over-sold sizes (this over-selling happens some times because the operator of the system fails to register some sales). Anyway, for the fiddle's example, the totals should literally be like | TOT4 | TOT5 | TOT6 | TOT7 | | 7 | -1 | 1 | 4 | and after we zero the over-sold ones, they should become | TOT4 | TOT5 | TOT6 | TOT7 | | 7 | 0 | 1 | 4 | In my fiddle I've attempted to calculate the subtraction of the two sums, but I don't know what I've dome wrong, as it calculates totally different results! I know I'm close, but I can't make it work. Can someone correct the final query for me? Thanks in advance.  |

| How to validate a complex nested data structure with Pydantic? Posted: 25 Sep 2021 08:13 AM PDT I had complex and nested data structure like below: { 0: { 0: {'S': 'str1', 'T': 4, 'V': 0x3ff}, 1: {'S': 'str2', 'T': 5, 'V': 0x2ff}}, 1: { 0: {'S': 'str3', 'T': 8, 'V': 0x1ff}, 1: {'S': 'str4', 'T': 7, 'V': 0x0ff}}, ...... }
It's a 2D dictionary basically. The innermost dict follows {Str: str, str:int, str:int}, while its outer dict always has integer as the key to index. Is there a way for Pydantic to validate the data-type and data structure? I mean if someone changes the data with a string as a key to the outer dict, the code should prompt an error. Or if someones tweaks the inner dict with putting 'V' value to a string, a checker needs to complain about it. I am new to Pydantic, and found it always requires a str-type field for any data... Any ideas?  |
| BeautifulSoup fails to tag HTML correctly Posted: 25 Sep 2021 08:12 AM PDT I'm using BeautifulSoup to parse a simple HTML table. Due to some inconsistency in the data BeautifulSoup seems to fail parsing and tagging the content correctly. Here is the code: import requests from bs4 import BeautifulSoup page = 1 city = 'vantaa'.capitalize() URL = 'https://asuntojen.hintatiedot.fi/haku/?cr=1&t=3&l=0&search=1&sf=0&so=a&renderType=renderTypeTable&print=1&z={}&c={}'.format(page, city) page = requests.get(URL) soup = BeautifulSoup(page.content, "html.parser") tables = soup.find_all('tbody', attrs={'class':'odd'}) table = max(tables, key=len) rows = table.find_all('tr')
One correctly tagged row looks like this: <tr> <td class="area">Area 1</td> <td>Random string 1+1q, d</td> <td class="type">xb</td> <td class="cellAlignRight">38,00</td> <td class="cellAlignRight">132000</td> <td class="cellAlignRight">3474</td> <td class="cellAlignRight">1661</td> <td>1/1</td> <td>no</td> <td>less.</td> <td>oma <td>G<sub>2013</sub></td> </td> </tr>
However in the middle of the document something fails and the last rows are merged into one huge string <tr> <td class="neighborhood">Itä-hakkila</td> <td>1h, avokeitti&#...</td> <td class="houseType">rt</td> <td class="cellAlignRight">21,50</td> <td class="cellAlignRight">149000</td> <td class="cellAlignRight">6930</td> <td class="cellAlignRight">2017</td> <td>1/2</td> <td>ei</td> <td>hyvä</td> <td>oma <td>C<sub>2013</sub></td> </tr> <tr> <td class="neighborhood">Kivist&#246;</td> <td>1h+kt</td> <td class="houseType">kt</td> <td class="cellAlignRight">27,00</td> <td class="cellAlignRight">132000</td> <td class="cellAlignRight">4889</td> <td class="cellAlignRight">2018</td> <td>5/6</td> <td>on</td> <td>hyvä</td> <td>vuokra <td>C<sub>2013</sub></td> </tr>
which seems to be caused by this cell 1h, avokeitti&#..., which BeautifulSoup turns into <td>1h, avokeitti&#...</td> where as in the actual HTML on the webpage there is no such issue <tr> <td class="neighborhood">Itä-hakkila</td> <td>1h, avokeitti&#...</td> <td class="houseType">rt</td> <td class="cellAlignRight">21,50</td> <td class="cellAlignRight">149000</td> <td class="cellAlignRight">6930</td> <td class="cellAlignRight">2017</td> <td>1/2</td> <td>ei</td> <td>hyvä</td> <td>oma <td>C<sub>2013</sub></td> </tr>
I've tried using unicode.unescape() to the whole table which gives TypeError: 'NoneType' object is not callable, I've tried using re.sub(r'<', '<', text) to clean the whole table or single rows but that gives TypeError: expected string or bytes-like object. I circumvented this issue by just doing df_list = pd.read_html(page.text) to get the table out as a dataframe (and had to deal with other formatting issues instead), but the original issue was not solved.  |
| Why does C use FILE for stdin/stdout streams as well as file operations? Posted: 25 Sep 2021 08:15 AM PDT I have recently looked into files and input/output in C and quickly figured out that C uses a typedefed structure known as FILE which is commonly represented as a pointer to a structure.
This structure contains data about input and output so lower level parts of the operating system and kernel can easily manage input and output on a system, for example the size of the data being inputted, the type of data etc.
Basically is it purposefully made abstract since the way it works is very low level. I also know that something like FILE* x is commonly used by C programmers to represent input and output streams. C also allows FILE to commonly be used to point to a file. Why does C allow programmers to use FILE to represent files as well as input/output streams? To me this sounds very confusing as well as this the keyword FILE is literally called FILE and i would think it would often confuse new programmers into thinking it is used to ONLY point to files. So why is FILE used for both files and input/output?  |

| Android Glide - How do I load another image if my original image takes too long to load? Posted: 25 Sep 2021 08:13 AM PDT I'm loading an image from a url like this. If the image is taking a really long time to load, I want to load another image in its place so I used .error() to load an error image if the load fails, but this fail never gets called. Instead, the original image will eventually load after a long time, but I don't want to wait this long for the image to load. I tried using .timeout() but that doesn't do anything. Glide.with(this) .load(url) .error(Glide.with(errorUrl).load(imageView)) .into(imageView);

| Did I correctly understand the behaviour of next-redux-wrapper? Posted: 25 Sep 2021 08:12 AM PDT Tried to make counter with next-redux-wrapper, redux, Next.js. I've watched that when I clicked few counter button, then move to other page and came back to counter page, getServerSideProps initializes the counter into 3 again. I understand this library as it helps merge the result of dispatch during SSR to client redux store, but does not sync client store state to server redux store. Did I understand it correctly? Here is my code of counter app index.tsx
export const getServerSideProps = wrapper.getServerSideProps( (store) => async () => { store.dispatch(add(3)); return { props: {}, }; } ); const index = (props: any) => { const count = useSelector((state: AppState) => state.counter.count); const dispatch = useDispatch(); return ( <> <Link href='/book'>// move to other page then come back <a>move</a> </Link> <div>{count}</div> <button onClick={() => dispatch(add(1))}>+</button> <button onClick={() => dispatch(deleter(2))}>-</button> </> ); };

| html 5 canvas optimize redrawing [closed] Posted: 25 Sep 2021 08:12 AM PDT I have only one canvas, that has two "virtual" layers, that I can move (not canvases, but rectangles: green, brown) 
What I want to achieve in the future is a possibility to draw on "green" layer, and that it doesn't affect "brown" layer Now I'm adding brush tool to my editor, while using brush I save all the coordinates in array. Now array looks like this: [ { "lastPoint": { "x": 692, "y": 212 }, "currentPoint": { "x": 692, "y": 214 } }, { "lastPoint": { "x": 692, "y": 214 }, "currentPoint": { "x": 690, "y": 219 } } ... ]
After saving new coordinates to array, I do redraw of the canvas (it's getting worse (freezing) as I add more coordinates to array, obviously) My question on you is: how can I optimize this redraw on fly feature Codepen: https://codepen.io/IGentlich/pen/ZEyqqeJ (don't forget to File -> New first)  |

| Is there a way to match when the cell has several values Posted: 25 Sep 2021 08:13 AM PDT I am reading the data from one column F2:F11 of an excel worksheet that has this data |SAT| |SAT| |SAT| |SAT| |M, T, TH, SAT| |SUN, W| |SUN, W, F| |SAT| |T, F, SUN| |W|
I'm using this vba code to get the matches to Saturday (SAT) Sub Test() Dim WaterDays As Range Set myWKS = Worksheets("Water") Set WaterDays = myWKS.Range("F2:F11") For Each y In WaterDays vParts = Split(y, ",") For Each dy In vParts If StrComp(dy, "SAT") = 0 Then Debug.Print ("Yes") End If Next dy Next y End Sub
When I do this it will give me 5 matches (Yes), when there are actually 6 SATs in the column. What am I doing wrong here? Any help would be appreciated. Thanks  |
| How to help the Scala 3 compiler infer a path-dependent-type? Posted: 25 Sep 2021 08:12 AM PDT Suppose that, whenever type A can represent a less-than-perfectly-precise measurement of a physical value, I'll have an instance of Imprecise[A]. trait Imprecise[A]: type Precision val ord: Ordering[Precision] def precision(a: A): Precision
For example, this Bounds type has a given instance in its companion object: case class Bounds[N: Numeric](min: N, max: N): if summon[Ordering[N]].compare(min, max) > 1 then throw new IllegalArgumentException object Bounds: import scala.math.Numeric.Implicits.infixNumericOps import scala.math.Ordering.Implicits.infixOrderingOps given [N: Numeric]: Imprecise[Bounds[N]] with type Precision = N val ord = summon[Ordering[N]] def precision(rng: Bounds[N]) = rng.max - rng.min
Now my program can start dealing with the physical features that need to be observed: trait Feature[A: Imprecise]: type Observation = A val imprecise = summon[Imprecise[A]] type Precision = imprecise.Precision def within(bound: Precision) = new RequiredFeature(this, bound) class RequiredFeature(val feature: Feature[_], val min_precision: feature.Precision) case class Temperature(chamber_id: Int) extends Feature[Bounds[Double]] case class Pressure(chamber_id: Int) extends Feature[Bounds[Float]]
But when, at last, I try to make a required feature: val rf = Temperature(3).within(7.0)
the compiler complains Found: (7.0d : Double) Required: ?1.Precision where: ?1 is an unknown value of type exp.Temperature val rf = Temperature(3).within(7.0)
The code written so far can be made to compile if I forego any path-dependent types and pass the precision around everywhere as a regular generic type parameter. But what if I don't want to do that? Is there some strategy like the Aux pattern that will help the compiler see that this is a valid call to within?  |
| How to checkbox enable/disable with Struts 2 Posted: 25 Sep 2021 08:13 AM PDT I would like to show 2 checkboxs in my page (called box1 and box2). The default value is box1 = false and box2 = false. But I also have to enable box2 only if box1 = true. So I have created the following JS function : function myTest() { var check = document.getElementById('box1'); if (check.checked == false) { $('#box2').prop('disabled', true); } else { $('#box2').prop('disabled', false); } }
Now I don't really understand how to use myTest function in the JSP file. I have tried to use it with onload="myTest()" as follow, but it doesn't work (box2 is always disabled). <body onload="myTest()" /> <div class="form-group row"> <label class="col-sm-3 col-form-label required"> <s:text name="box1" /> </label> <div class="col-sm-9"> <s:checkbox id="box1" name="box1"> </s:checkbox> </div> </div> <div class="form-group row"> <label class="col-sm-3 col-form-label required"> <s:text name="box2" /> </label> <div class="col-sm-9"> <s:checkbox id="box2" name="box2"></s:checkbox> </div> </div>

| Website monthly visits are (daily visits x 30)? Posted: 25 Sep 2021 08:13 AM PDT I'm trying to estimate if showing ads on my website can become the main source of income by estimating the traffic of somewhat similar sites. There are several websites, offering traffic statistics and presenting similar data. For instance, here is their statistics for stackoverflow.com: http://www.similarweb.com/website/stackoverflow.com http://www.trafficestimate.com/stackoverflow.com http://www.siteworthtraffic.com/report/stackoverflow.com According to these data, stackoverflow.com receives just around 150 million monthly visits. Does it mean that I should divide this number by 30 in order to get the number of daily visits, resulting in only 5 million visits a day, which is worth only ~15 000$ income a day? Because that's quite a low number for such a monster. Or in reality it receives around 150 million users each day, making around 500 000$ a day?
Another case - VK.com: http://www.trafficestimate.com/vk.com http://www.similarweb.com/website/vk.com#overview http://www.siteworthtraffic.com/report/vk.com According to vk.com they have 350 millions active users. So the data, presented by trafficestimate, similarweb and siteworthtraffic don't look consistent.
Another case - meduza.io. meduza.io is a news site, which was created by ~30 people team, who left lenta.ru after polytical persecution of their chief editor. They're making ~3 million visitors a month or ~ 10 million page views.
http://www.trafficestimate.com/meduza.io http://www.similarweb.com/website/meduza.io#overview With 10$/1000 page views, they could achieve just 100 000$/month, which is barely or not enough to pay salaries to 30 people in Europe.  |
| How to unset global variable in php? Posted: 25 Sep 2021 08:13 AM PDT I know very basic of php and web programming. Here is my php code. I have seen couple of similar questions. They unset global variable with unset function. I want every time user open the url, a username and password prompt and after entering username password if it is correct download the file and delete username and password and if is wrong delete username and password and again prompt for username password. <?php function destroy_foo() { if (isset($_SERVER['PHP_AUTH_USER'])) { unset($_SERVER['PHP_AUTH_USER']); } if (isset($_SERVER['PHP_AUTH_PW'])) { unset($_SERVER['PHP_AUTH_PW']); } } if (!isset($_SERVER['PHP_AUTH_USER'])) { header('WWW-Authenticate: Basic realm="My Realm"'); header('HTTP/1.0 401 Unauthorized'); echo 'Text to send if user hits Cancel button'; exit; } else { echo "<p>Hello {$_SERVER['PHP_AUTH_USER']}.</p>"; echo "<p>You entered {$_SERVER['PHP_AUTH_PW']} as your password.</p>"; $file = 'welcome.txt'; if($_SERVER['PHP_AUTH_PW'] == "admin" && $_SERVER['PHP_AUTH_USER'] =="admin"){ destroy_foo(); if (file_exists($file)) { //Do some task destroy_foo(); exit; } } else { //Do some task destroy_foo(); } } ?>
At the moment username and password stays in the global variables for some reason. I'd appreciate if you could give suggestion or hint. EDIT This did not work either: function destroy_foo() { if (isset($_SERVER['PHP_AUTH_USER'])) { unset($_SERVER['PHP_AUTH_USER']); $_SERVER['PHP_AUTH_USER'] = null; } if (isset($_SERVER['PHP_AUTH_PW'])) { unset($_SERVER['PHP_AUTH_PW']); $_SERVER['PHP_AUTH_PW'] = null; } }
