Answer : Here are some commercial providers that have the type of chart you're looking for: ChartFX for .NET - Gallery of available charts including 3D surface Nevron Chart for .NET - Gallery of available surface charts You may have already come across this, but I thought I'd point out the CodeProject article Plot 3D surfaces . I'm not sure if it's feature set is sufficient for your requirements, but it's worth investigating if you haven't already. The obvious advantage is that it's free and open source (so that you might expand it for your particular needs). Example screenshot: Another possible alternative that looks reasonably complete is the F# for Visualization library. This is commercial, but by the look of it would do more that what you might need. Don't let the fact that it is designed for F# put you off - you should still to use it directly from C# (or perhaps with a minor amount of interop to make things cleaner). Certainly, the...

Answer : There could be some legitimate reasons why this won't work well. These may not apply to you, and if you review the documentation of your charger, you should be able to tell whether these things apply. Probably you are aware that it is not safe to float lithium ion batteries at 4.2V indefinitely. Because of this, all Lithium ion chargers use some method of recognizing end of charge. Typically, end of charge is determined by how much current flows into the battery. For a single 18650 cell, end of charge may be defined as the point where charge current drops to 25mA during the CV stage. But with 9 cells in parallel, it may never drop that low. Which brings me to the second point. Timeout. Many charger IC's will not allow an indefinite amount of time for charge to complete. This is a backup safety in case a defective battery is present, or something else prevents the primary charge termination condition from occurring. Typically this timeout would be set to some n...

Answer : There seems to be a more direct way to do the same thing using regionprops with cache=False . I generated labels using skimage.segmentation.slic with n_segments=10000 . Then: rps = regionprops(labels, cache=False) [r.area for r in rps] My understanding of the regionprops documentation is that setting cache=False means that the attributes won't be calculated until they're called. According to %%time in Jupyter notebook, running the code above took 166ms with cache=False vs 247ms with cache=True , so it seems to work. I tried an equivalent of the other answer and found it much slower. %%time ard = np.empty(10000, dtype=int) for i in range(10000): ard[i] = size(np.where(labels==0)[1]) That took 34.3 seconds. Here's a full working example comparing the two methods using the skimage astronaut sample image and labels generated by slic segmentation: import numpy as np import skimage from skimage.segmentation import slic from skimage.data import a...

Answer : For those who are using bootstrap4: classes for responsive floats and removed .pull-left and .pull-right since they’re redundant to .float-left and .float-right. More information from Bootstrap4 migration notes: Here Your form-group is aligned as far to the right as possible – but the content within it is not. You have only 4+4+2 wide columns in there, so you are “two columns short”, in the 12-column grid used by bootstrap. You might want to simply offset the first one of those by 2, by adding col-xs-offset-2 class – then the alignment should be closer to what you want to achieve. Bootstrap column layout will basically split the row into 12 columns. Here you are only defining 10 out of the twelve columns, which is why you have space left on the right. Try <div class="form-group pull-right"> <div class="col-xs-4 col-xs-offset-2"> <input type="text" class="form-contro...

Answer : Javascript objects don't have a guaranteed inherent order, so there doesn't exist a "reverse" order. 4.3.3 Object An object is a member of the type Object. It is an unordered collection of properties each of which contains a primitive value, object, or function. A function stored in a property of an object is called a method. Browsers do seem to return the properties in the same order they were added to the object, but since this is not standard, you probably shouldn't rely on this behavior. A simple function that calls a function for each property in reverse order as that given by the browser's for..in, is this: // f is a function that has the obj as 'this' and the property name as first parameter function reverseForIn(obj, f) { var arr = []; for (var key in obj) { // add hasOwnPropertyCheck if needed arr.push(key); } for (var i=arr.length-1; i>=0; i--) { f.call(obj, arr[i]); } } //usage reverseFo...

Answer : I don't know what exactly you are calling handshake, but I propose this command that will probably capture more than 95% of what you can want: tcpdump -ni eth0 "tcp port 443 and (tcp[((tcp[12] & 0xf0) >> 2)] = 0x16)" Now what does it do: eth0 : is my network interface, change it if you need tcp port 443 : I suppose this is the port your server is listening on, change it if you need tcp[((tcp[12] & 0xf0) >> 2)] = 0x16 : a bit more tricky, let's detail this below tcp[12] means capturing the 13th byte of the tcp packet, corresponding to first half being the offset, second half being reserved. The offset, once multiplied by 4 gives the byte count of the TCP header, meaning ((tcp[12] & 0xf0) >> 2) provides the size of the TCP header. The first byte of a TLS packet define the content type. The value 22 (0x16 in hexadecimal) has been defined as being "Handshake" content. As a consequence, tcp[((tcp[12] ...
