[ "How can I build variants of an executable with one makefile?", "I have one set of source files from which I need to generate multiple variants of an executable. For example I need to generate app1.elf, app2.elf, app3.elf from the same main.c and comm.c. The difference between each of the apps is a node address, a parameter that is passed down in the invocation of gcc. i.e.:\n\ngcc -DNODE=1 -oapp1.elf main.c \ngcc -DNODE=2 -oapp2.elf main.c \ngcc -DNODE=3 -oapp3.elf main.c \n\n\nLet's assume that I have the following files: \n\n\nsrc/main.c\nsrc/comm.c\n\n\nWhen I run the Makefile as so:\n\n\n make all_nodes\n\n\nmake only builds app1.elf with the following output:\n\n\n Built app1\n Built app2\n Built app3 \n\n\nFAIL!\nThe output seems to suggest that it worked, however it only generates one executable, namely app1.elf. Anybody care to point out what I'm doing wrong? \n\nTo further explain my Makefile, I've created a cleanobjs target to clean out the objects in the ./obj subdirectory. This is my attempt at having 'make' rebuild the obj files with the new node address, but it fails. Am I using 'make' in a way it wasn't intended to be used? I know I can also create a batch file to run make (something I've done sucessfully) but I'd like to know what I'm doing wrong.

To achieve this I have set the minimumInteritemSpacing to 1.0 and the cell width to 159.5 pt such that two cells will add up to 319 pt leaving a single point for the space. The problem appears when I want the third button to be the full width of the view because the flow layout causes the spacing to be 0.5 pt despite having been told to keep a minimum of 1.0. (see screenshot 1)\n\n\n\nThe code for setting up the spacing happens in \n\n-(void)viewDidLoad\n{\n UICollectionViewFlowLayout *flowLayout = (UICollectionViewFlowLayout *)[[self collectionView] collectionViewLayout];\n [flowLayout setMinimumInteritemSpacing:1.0];\n [flowLayout setMinimumLineSpacing:1.0]; \n}\n\n\nand the sizing of the cells in\n\n- (CGSize)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout *)collectionViewLayout sizeForItemAtIndexPath:(NSIndexPath *)indexPath\n{\n if (indexPath.row == 2) {\n return CGSizeMake(320 ,151);\n }\n return CGSizeMake(159.5, 151);\n}\n\n\nIf, on the other hand, I don't make the third button full width the spacing behaves as expected though it shouldn't affect the inter item spacing of a different row.

Sadly, the original site was built for desktops but many of our sales reps are using phones/tablets to access it. One plus to this however, is that all of them are supplied with android tablets. No need for apple support so if a solution would not work for an apple device it isn't a big deal. \n\nI know that you can prevent page zooming using meta tags, but is there a way to make the zoom levels persist over postback? If there are any ways to handle this using javascript, html, or asp.net any help would be greatly appreciated. \n\nEdit: Found a post here talking about detecting zoom levels.

As you may know already, all these will result in sparse arrays. \n\nBut why are we allowed to do the above thnigs ? Why would anyone want to create an array whose length is 20 by default (as in the first example) ?

Why would you use delete instead of just removing the element from the array ? \nCould anyone provide some use-cases for these statements ? \n\nI have been searching for some answers for ~3 hours.

No sources I read explained, or at least tried to explain, why we were allowed to create sparse arrays in the first place. Except for You Don't Know JS: Types & Grammar, here is what the book says about why JavaScript allows the creation of sparse arrays:\n\n\n An array that has no explicit values in its slots, but has a length property that implies the slots exist, is a weird exotic type of data structure in JS with some very strange and confusing behavior. The capability to create such a value comes purely from old, deprecated, historical functionalities (\"array-like objects\" like the arguments object).\n\n\nSo, the book implies that the arguments object somehow, somewhere, uses one of the examples I listed above to create a sparse array. So, where and how does arguments use sparse arrays ?\n\nSomething else that is confusing me is this part in the book \"JavaScript: The Definitive Guide 6th Edition\":\n\n\n Arrays that are sufficiently sparse are typically implemented in a slower, more memory-efficient way than dense arrays are`.\n\n\n\"more memory-efficient\" appears like a contradiction to \"slower\" to me, so what is the difference between the two, in the context of sparse arrays especially ? Here is a link to that specific part of the book." ]

I grouped the data points into six distinct clusters numbered 0-5, and put the cluster number at each cluster's mean coordinates.\nThis outputs the following graph:\n\nI was wondering how I can add a legend to this plot specifying the color and its corresponding cluster number. plt.legend() requires the style code to be in the format such as red_patch but it does not seem to take numeric values (or the numeric strings). How can I add this legend using matplotlib then? Is there a way to translate my numeric value color codes to the format that plt.legend() takes? Thanks a lot!" ]

How would you break up this markup into Marionette views?\n\n\nIs it possible/advisable to arrange Marionette views so that this exact markup is produced?\nHow should the Bootstrap tabs be modeled?\nHow should the accounts table and accounts chart be modeled? I was thinking that this would be a Marionette Layout with two regions, but then started thinking why? Isn't the purpose of a layout to give the ability to instantiate different kinds of views in each of its regions? Here I will always have two fixed views, so is layout an overkill?\n\n\nThanks in advance for your time." ]
