| How do I copy multiple files in another directory in python? Posted: 26 Sep 2021 08:06 AM PDT I have a dataset including images in ascending order, like images_0001.png images_0002.png . . images_0500.png and so on. I want to copy specific range of this images into another directory. For example, 100 images will be coppied between images_0210.png to images_0310.png. Does anybody have any idea how to do that?

| Trouble grasping "error due to conversion" in single-precision IEEE-754 Posted: 26 Sep 2021 08:06 AM PDT Let me preface the question by saying that I understand why values such as 0.1, 3.14, 0.2, and other values not composable of combinations of powers of two are ultimately unrepresentable by IEEE-754 formats, and that they may only be approximated as best as the precision allows. What I am having trouble understanding is why attempting to represent the value 2-23 results in a slight margin of error. 2-23 is exactly equal to 1.1920928955078e-7, or 0.00000011920928955078. In single-precision IEEE-754, it can be constructed as follows: - The sign bit is
0 - The biased exponent is
104 (or 0b01101000 in binary) to account for the 127-bias, leading to -23 being the final exponent value - The mantissa's bit field is entirely composed of
0s, its ultimate value being 1.0 when the implicit 1-bit is accounted for However, storing this particular bit sequence in memory and printing it out in decimal notation, with 25 digits of precision past the decimal point results in the following: 0.0000001192092895507812500 ^ | margin of error starts here
This value contains an error of exactly 1.25e-21. On this interactive website, this error value is referred to as an "Error due to conversion". I am having trouble grasping this - because I understand, for example, why a value such as +2.76 cannot be exactly represented by a single-precision bitfield. No combination of negative powers of two in the mantissa scaled by the value in the exponent can exactly represent 2.76, so the next closest approximation is chosen. Contrary to that, the value 2-23 is able to be stored exactly in a single-precision bitfield, yet when converted back to a decimal notation, an error appears. There's clearly some sort of misunderstanding on my part, but I can't figure out where exactly.  |
| Iterating over NumPy array for timestep Posted: 26 Sep 2021 08:06 AM PDT I have 5 columns in an array that are datetime type values. There are 100k+ values in each column The values are the datetime for a timeline going from 2015-01-15 00:30 to 2020-12-31 23:00 in 30 minute increments. Basically what I want to do is to loop through values in the array, and check if the current value is an exact 30 minute timestep from the last value. In an array with columns this would be the value above the current value being investigated Theres probably a few ways to do this, but I've included a pseudocode sample of how I'm thinking about it for row in _the_whole_array : for cell in row: if cell == to the 30 minute timestep of the cell above it continue iterating else: store that value return the smallest timestep found, and the biggest timestep found
I have looked at for loops as well as nditer but I'm getting errors with iterating over datetimes, and I'm also wondering how I can find the cell value above the current cell value above it. Any help hugely appreciated  |

| Laplacian filter returning very black image Posted: 26 Sep 2021 08:05 AM PDT I'm trying to apply a local Laplacian filter to an image using blockproc but the result I get is far darker than the result in the textbook. I've seen some other posts about this same problem but I'm not sure what exactly I'm failing to grasp. My code: img1 = im2double(imread('Fig0352(a)(blurry_moon).tif')); kernel = [0 1 0; 1 -4 1; 0 1 0]; %generate laplacian image fun = @(block_struct)laplacian_kernel(block_struct.data, kernel); img2 = blockproc(img1, [3 3], fun, 'PadPartialBlocks', true, 'TrimBorder', true); img3 = img2(:, 1:end-2);%crop extra two columns added by last passthrough of blockproc img4 = imsubtract(img1,img3);%get enhanced image %display figure; subplot(2,2,1); imshow(img1) subplot(2,2,2); imshow(img3); subplot(2,2,3); imshow(img4); function f = laplacian_kernel(img, kernal) %want to pad this 3x3 chunk of the image so we don't exceed the bounds of %the array when doing laplacian img1 = padarray(img, [1 1]); out = zeros(size(img1)); for i = 2 : (length(img1)-1) for j = 2 : (length(img1)-1) neighborhood = img1(i-1: i+1, j-1: j+1);%get neighborhood out(i,j)= sum(neighborhood .* kernal, 'all'); end end f = out(2:length(img1)-1, 2:length(img1)-1);%remove padding end
And the image I'm getting is 
The laplacian is the image on the top right, which is far darker than what is shown in the book. The image from the book looks much more like this: 
I know it's still very dark (and a small image, sorry) but there is much more detail to it than what I'm producing with my custom code. What am I doing wrong with my laplacian? I've tried rewriting the code multiple times but always get more or less the same result. If I use nlfilter, my result matches that in the book. However, it takes so much more time I don't like to use it. I'm clearly stumbling when piecing the blocks back together with blockproc but I can't conceptualize where I'm going wrong. Here are my results when using nlfilter: img1 = im2double(imread('Fig0352(a)(blurry_moon).tif')); kernel = [0 1 0; 1 -4 1; 0 1 0]; k2 = [1 1 1; 1 -8 1; 1 1 1]; fun = @(x)laplacian_kernel(x, kernel); img2 = nlfilter(img1, 'indexed', [3 3], fun); img3 = imsubtract(img1, img2); figure; subplot(1,3,1); imshow(img1); title('original image'); subplot(1,3,2); imshow(img2); title('laplacian using nlfilter'); subplot(1,3,3); imshow(img3); title('enhanced image'); function f = laplacian_kernel(img, kernal) f = sum(img.*kernal, 'all'); end
With output: 
Clearly, the results from nlfilter are much better. I'm just not sure where I'm going wrong with blockproc.  |
| PHP - How to use config file variables in a function's array? Posted: 26 Sep 2021 08:05 AM PDT I could not find an example of what I'm trying to accomplish. I guess I don't know the proper search words to use. I have a working script but I want to make it more flexible by adding a main, admin editable config file. I have the following function: function ip_is_mobile($ip) { $pri_addrs = array( '66.87.0.0-66.87.255.255', // Sprint mobile '174.192.0.0-174.255.255.255' // Verizon mobile ); $long_ip = ip2long($ip); if($long_ip != -1) { foreach($pri_addrs AS $pri_addr) { list($start, $end) = explode('-', $pri_addr); // IF IS a mobile IP if($long_ip >= ip2long($start) && $long_ip <= ip2long($end)) return true; } } return false; }
I would like to replace the hard-coded IP address ranges, in the function, with variables or definitions which will be set in the main config file so that the config file has something similar to the following: // Mobile IP address ranges. Add as many as needed. $MobileIPs['0']="66.87.0.0-66.87.255.255"; $MobileIPs['1']="174.192.0.0-174.255.255.255"; $MobileIPs['2']="85.110.50.0/24";
My goal is to give the admin an easy to read and understand way of adding as many IP address ranges as necessary (probably 20 max). I'm not opposed to totally rewriting the function if there is a better, more efficient way. In addition to IP ranges, it would be advantageous if CIDR's could also be specified; as indicated in the last code line above. What edits do I need to make to the function and what would the corresponding lines in the main config file be so that the user can add any number of ranges or CIDR's?  |

When hotspot is off, device has these addresses: PAN_sprout:/ $ ip addr 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: dummy0: <BROADCAST,NOARP,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN group default qlen 1000 link/ether 46:85:2d:8f:9a:8e brd ff:ff:ff:ff:ff:ff inet6 fe80::4485:2dff:fe8f:9a8e/64 scope link valid_lft forever preferred_lft forever 3: ip_vti0@NONE: <NOARP> mtu 1480 qdisc noop state DOWN group default qlen 1 link/ipip 0.0.0.0 brd 0.0.0.0 4: ip6_vti0@NONE: <NOARP> mtu 1500 qdisc noop state DOWN group default qlen 1 link/tunnel6 :: brd :: 5: sit0@NONE: <NOARP> mtu 1480 qdisc noop state DOWN group default qlen 1 link/sit 0.0.0.0 brd 0.0.0.0 6: ip6tnl0@NONE: <NOARP> mtu 1452 qdisc noop state DOWN group default qlen 1 link/tunnel6 :: brd :: 8: rmnet0: <UP,LOWER_UP> mtu 2000 qdisc pfifo_fast state UNKNOWN group default qlen 1000 link/[530] 9: rmnet_data0: <UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UNKNOWN group default qlen 1000 link/[530] inet6 fe80::9e2:b3d5:84e6:14c/64 scope link valid_lft forever preferred_lft forever 10: rmnet_data1: <UP,LOWER_UP> mtu 1464 qdisc htb state UNKNOWN group default qlen 1000 link/[530] inet 10.140.85.190/30 scope global rmnet_data1 valid_lft forever preferred_lft forever inet6 2001:14bb:a0:5545:818d:5109:4166:b991/64 scope global dynamic mngtmpaddr valid_lft forever preferred_lft forever inet6 fe80::818d:5109:4166:b991/64 scope link valid_lft forever preferred_lft forever ... 25: r_rmnet_data8: <> mtu 1500 qdisc noop state DOWN group default qlen 1000 link/[530]

As you see, wlan0 was added, but no callback function was called. Callback functions do work otherwise, for example, when I turn cellular network on/off. Question is: what do I need to do in order to get callback functions called when WiFi hotspot is turned on/off. Edit: Based on Sergio Pardo's answer, I created this: val hotSpotReceiver = object : BroadcastReceiver() { override fun onReceive(contxt: Context, intent: Intent) { val action = intent.action if ("android.net.wifi.WIFI_AP_STATE_CHANGED" == action) { val state = intent.getIntExtra(WifiManager.EXTRA_WIFI_STATE, 0) if (WifiManager.WIFI_STATE_ENABLED == state % 10) Log.d(TAG, "HotSpot is enabled") else Log.d(TAG, "HotSpot is disabled") } } } } this.registerReceiver(hotSpotReceiver, IntentFilter("android.net.wifi.WIFI_AP_STATE_CHANGED"))
It can be used to detect when WiFi hotspot is enabled or disabled and answers the title of the question. But it does not help in getting the NetworkCallbacks called. The callbacks would have allowed me to learn hotspot's local IP address and interface name. Is there some other way to figure that out? Edit: It turned out that when the above hotSpotReceiver logs "Hotspot is enabled", there is delay before the hotspot interface gets its IP addresses and routes. The missing network callbacks would help.  |

| Change header name for each column in tableau Posted: 26 Sep 2021 08:05 AM PDT I have a data with ID's and their qualification such as certifications, Advance degree only, Multiple degrees and Single certification in a Yes/No format I am trying to show the data in 4 bar charts like 1) No Certifications (3) 2) Only Advance Degree (6) 3) Single certifications (17) and 4) Multiple Degree (19). Counts are mentioned in the bracket. I need to rename each column with the above-mentioned header name. However, if change name of one column, the other column name also changes. Kindly suggest adding an individual name for each column. The graph looks like below.

| What do we mean by contextually autoescaping? Posted: 26 Sep 2021 08:06 AM PDT While reading about the Closure Templates I encountered the following statement: Closure Templates are contextually autoescaped to reduce the risk of XSS. As far as I know escaping is removing ambiguity in the input string as described here. I am not sure what really that means, perhaps an explanation with real world example would be really helpful.  |
