limits

CSS allows an HTML element to have multiple classes: <div class="cat persian happy big"> Nibbles </div> But is there a limit on how many classes are allowed per item? meagar You're only limited by the maximum length of an (X)HTML attribute's value, something covered well by this answer . Browsers are often very forgiving of standards violations, so individual browsers may allow much longer class attributes. Additionally you are likely able to add a practically infinite number of classes to a DOM element via JavaScript, limited by the amount of memory available to the browser. For all intents

Until Office 2007, Excel has a maximum of 65,000 rows. Office 2007 bumped that up to a max of 1 million rows, which is nicer of course; but I'm curious -- why is there a limit at all? Obviously, performance will slow down exponetially as you increase the spreadsheet size; but it shouldn't be very hard to have Excel optimize for that by starting with a small sheet and dynamically "re-sizing" it only as needed. Given how much work it must have been to increase the limit from 65K to 1 million, why didn't they go all the way so it's limited only by the amount of available memory and disk space?

I have an application for sending out say around 100+ tweets every day. I am using OAuth for authentication. The twitter API says that post messages are not rate limited. However I am receiving the following error: 403:The request is understood, but it has been refused. An accompanying error message will explain why. This code is used when requests are being denied due to update limits ( http://support.twitter.com/forums/10711/entries/15364 ). error - User is over daily status update limit. request - /1/statuses/update.json Relevant discussions can be on the Internet at: http://www.google.co

I'd like to keep the number of cores in my GKE cluster below 3. This becomes much more feasible if the CPU limits of the K8s replication controllers and pods are reduced from 100m to at most 50m. Otherwise, the K8s pods alone take 70% of one core. I decided against increasing the CPU power of a node. This would be conceptually wrong in my opinion because the CPU limit is defined to be measured in cores. Instead, I did the following: replacing limitranges/limits with a version with "50m" as default CPU limit (not necessary, but in my opinion cleaner) patching all replication controller in the

The method I've devised so far is this: func randRange (lower : Int , upper : Int) -> Int { let difference = upper - lower return Int(Float(rand())/Float(RAND_MAX) * Float(difference + 1)) + lower } This generates random integers between lower and upper inclusive. Here's a somewhat lighter version of it: func randRange (lower: Int , upper: Int) -> Int { return lower + Int(arc4random_uniform(UInt32(upper - lower + 1))) } This can be simplified even further if you decide this function works with unsigned values only: func randRange (lower: UInt32 , upper: UInt32) -> UInt32 { return lower +

On my 64-bit machine, this C# code works: new byte[2L * 1024 * 1024 * 1024 - 57] but this one throws an OutOfMemoryException : new byte[2L * 1024 * 1024 * 1024 - 56] Why? I understand that the maximum size of a managed object is 2 GB and that the array object I'm creating contains more than the bytes I want. Namely, there is 4 bytes (or 8?) for the syncblock number, 8 bytes for MethodTable reference and 4 bytes for the size of the array. That's 24 bytes including padding, so why can't I allocate an array with 2G - 24 bytes? Is the maximum size really exactly 2 GB? If that's the case, what is
