"Mobile emulator/simulator Detox screenshot artifacts differ when run on different hosts",
"I'm taking screenshots with Detox locally and committing them to my source repo. In continuous integration (Circle/macOS executor), I'm running the test again and detecting any file differences. Basically a form of visual regression testing. Unexpectedly, the PNG files differ when run on CI. This is occurring for both iOS and Android. Inspecting the resulting PNG file that was run on CI, the RGB values differ randomly by one. For example RGB(23,42,23) vs RGB(23,42,24). The difference could be in any of the color channels. Spot checking the result, it's usually just one channel (but presumably could be more than one).\n\nSome notes:\n\n\nFor Android, it looks like the adb screencap command is used by Detox, which looks like it can emit raw or PNG output (Detox is using the latter).\nThe same emulator (Android) and simulator (iOS) type is being used in the tests\n\n\nSo my questions are:\n\n\nIs PNG output deterministic given the same input?\nIs adb screencap (and the equivalent on iOS used by Detox) causing this?"

Is this the \"React Way\" to do things?\n\nI see the need when using context (Like in Redux Provider), but otherwise, I am not sure.\n\nEdit: By \"Regular JS Library\" I am referring to including a file in the build that waits for DOM ready and then just calls a webfont loader directly, without using a wrapping element in React."

"Likert Rank ordering optimization heuristic possible?",
"I can't find the type of problem I have and I was wondering if someone knew the type of statistics it involves. I'm not sure it's even a type that can be optimized.\n\nI'd like to optimize three variables, or more precisely the combination of 2. The first is a likert scale average the other is the frequency of that item being rated on that likert scale, and the third is the item ID. The likert is [1,2,3,4]\n\nSo:\n\n3.25, 200, item1. Would mean that item1 was rated 200 times and got an average of 3.25 in rating.\n\nI have a bunch of items and I'd like to find the high value items. For instance, an item that is 4,1 would suck because while it is rated highest, it is rated only once. And a 1,1000 would also suck for the inverse reason.\n\nIs there a way to optimize with a simple heuristic? Someone told me to look into confidence bands but I am not sure how that would work. Thanks!"

"threading route params with react-router and redux container components",
"Hopefully this is a simple question that I'm just having trouble phrasing.\nPrior to using react-router:\n\nMy app is structured in a way that there is a list of items, clicking an item sets a selected state item in my redux store.\n\nWhen an item is selected, app renders a container component. This component is quite complex and has several other child container components where I use a selector to getSelectedItem(state).\n\nNow that is fine, but when switching to react-router, now the only component with knowledge of the selected value is the most parent component which gets the this.props.params.selected value. Because selected is no longer being stored in the state, it is managed by the router, is it necessary for me to thread the selected value through to all the children container components as well? Where i would now use a selector like getItem(state, selected) or something to that effect.\n\nHopefully that's clear, perhaps i should have been threading that value through all along? Not sure on best practice there. Thanks."

"Add Fragment dependent on a Loader result",
"My goal is to write a messenger Activity. Right now there are two kinds of Messages implemented: \n - Simple Text \n - Gallery \nIn my messenger Activity I use the LoaderManager.LoaderCallbacks functions in order to asynchronically query the Messages table in my DB. That query returns (amongst other information): \n - What kind of Message is it (Simple Text or Gallery) \n - What is the ID of that data in the type-specific table (Gallery leads to a table full of pictures, for example) \nNow I have a Fragment for Simple Text and one for Gallery. Those need the data's ID and then use a Loader to query its table in the DB. Ideally I would just dynamically add that type-specific Fragment for every message I have. \n\nIn pseudo code:\n\nfunction allMessagesAreLoaded() {\n for (message : messages) {\n if message is simpleTextMessage then\n add simpleTextMessageFragment\n else if message is gallery then\n add galleryFragment\n end if\n }\n}\n\n\n\nNow to my question:\nIt is not best practice to use Fragments in this case according to this source: http://www.androiddesignpatterns.com/2013/08/fragment-transaction-commit-state-loss.html \nWhat is the way to go to have an encapsulated layout and function set/class that can be programmatically added during runtime depending on a DB query result? \nMaybe I'm looking at it from the wrong direction.

"What is smallest offset for which I can safely omit overflow checking when I add it to a pointer?",
"Can I expect that any \"data\" pointer in user space programs lies in a safe distance from the addresses 0 and 0xffffffff..., so that I can safely add a small offset to the pointer without checking for an overflow? What is the largest positive n for which I can safely assume that p + n doesn't overflow when p is a char pointer into a constant character buffer or a dynamically allocated string (on a modern >= 32-bit operating system)?\n\nTo avoid confusion: I'm talking about overflow checking, not about bounds checking. For example: If you have a pointer p to the beginning of a string with m chars and you want to access the char at the positive offset i, then you either need to check that i < m or you can check indirectly p + i < p + m. However, in the latter case you also have to make sure that p + i doesn't overflow, i.e. you have to make sure that p + i >= p.\n\nUpdate: Ok, p + i is not valid standard C if i > m, regardless of whether p + i is actually dereferenced or whether it overflows. However, the question I'm really interested in is whether there is a small n for which p + n won't overflow in practice. Answering this question obviously requires some knowledge about how modern operating systems organize the address space.\n\nUpdate2: It would already be very interesting to hear about any one particular platform, even if it's not generalizable. Preferably not some obscure embedded one. x86 or Power-based 32-bit Win, Linux and Mac would be most interesting."

"Is the Leptonica implementation of 'Modified Median Cut' not using the median at all?",
"I'm playing around a bit with image processing and decided to read up on how color quantization worked and after a bit of reading I found the Modified Median Cut Quantization algorithm.\n\nI've been reading the code of the C implementation in Leptonica library and came across something I thought was a bit odd.\n\nNow I want to stress that I am far from an expert in this area, not am I a math-head, so I am predicting that this all comes down to me not understanding all of it and not that the implementation of the algorithm is wrong at all.\n\nThe algorithm states that the vbox should be split along the lagest axis and that it should be split using the following logic\n\n\n The largest axis is divided by locating the bin with the median pixel\n (by population), selecting the longer side, and dividing in the center\n of that side. We could have simply put the bin with the median pixel\n in the shorter side, but in the early stages of subdivision, this\n tends to put low density clusters (that are not considered in the\n subdivision) in the same vbox as part of a high density cluster that\n will outvote it in median vbox color, even with future median-based\n subdivisions. The algorithm used here is particularly important in\n early subdivisions, and 3is useful for giving visible but low\n population color clusters their own vbox. This has little effect on\n the subdivision of high density clusters, which ultimately will have\n roughly equal population in their vboxes.\n\n\nFor the sake of the argument, let's assume that we have a vbox that we are in the process of splitting and that the red axis is the largest. In the Leptonica algorithm, on line 01297, the code appears to do the following\n\n\nIterate over all the possible green and blue variations of the red color\nFor each iteration it adds to the total number of pixels (population) it's found along the red axis\nFor each red color it sum up the population of the current red and the previous ones, thus storing an accumulated value, for each red \n\n\nnote: when I say 'red' I mean each point along the axis that is covered by the iteration, the actual color may not be red but contains a certain amount of red\n\nSo for the sake of illustration, assume we have 9 \"bins\" along the red axis and that they have the following populations\n\n\n 4 8 20 16 1 9 12 8 8\n\n\nAfter the iteration of all red bins, the partialsum array will contain the following count for the bins mentioned above\n\n\n 4 12 32 48 49 58 70 78 86\n\n\nAnd total would have a value of 86\n\nOnce that's done it's time to perform the actual median cut and for the red axis this is performed on line 01346\n\nIt iterates over bins and check they accumulated sum. And here's the part that throws me of from the description of the algorithm. It looks for the first bin that has a value that is greater than total/2\n\nWouldn't total/2 mean that it is looking for a bin that has a value that is greater than the average value and not the median ? The median for the above bins would be 49\n\nThe use of 43 or 49 could potentially have a huge impact on how the boxes are split, even though the algorithm then proceeds by moving to the center of the larger side of where the matched value was.. \n\nAnother thing that puzzles me a bit is that the paper specified that the bin with the median value should be located, but does not mention how to proceed if there are an even number of bins.. the median would be the result of (a+b)/2 and it's not guaranteed that any of the bins contains that population count. So this is what makes me thing that there are some approximations going on that are negligible because of how the split actually takes part at the center of the larger side of the selected bin.\n\nSorry if it got a bit long winded, but I wanted to be as thoroughas I could because it's been driving me nuts for a couple of days now ;)"

Rather than given tab completion it jumps four spaces. \n\nWhen I run emacs in normal GUI mode there is fine tab completion. \n\nIs there a way to fix that for text mode?\n\nI'm using Linux Mint 15, Emacs 24.3 and IPython 1.1.0"
