PHP: Split string into array, like explode with no delimiter How much marmelade can I bring into the US? I want to bring homemade berry marmelade in little glass jars with me to the US from Europe as gifts for friends. I have found the following site on importing foods into the US  and would assume that marmelade falls under the condiments category, which should be admissible. However, I am wondering however if there is any limit to how much one is allowed to bring. Will there be any issues if, say, I bring 3 kilograms (6 lbs 10 oz)?   Also on related note, would they be suspiscious when they see many glass jars in my bag? Do I risk getting my bag searched or getting asked what the jars are? Is there anything I can do to avoid any such trouble? Using a non-centralized structure for tex files - similar to \graphicspath What is the significance of momentum? I just want to get an idea what  is. I know the mathematical meaning that momentum is $mv$ where $v$ is velocity. But I don't know its significance. Like I know that Acceleration is how velocity is changing with respect to time, I wanted to get feel of what momentum really is? Is the ideal $I = \{f\mid f (0) = 0\}$ in the ring $C [0, 1]$ of all continuous real valued functions on $[0, 1]$ a maximal ideal? Is the ideal $I = \{f \mid f (0) = 0\}$ in the ring $C [0, 1]$ of all continuous real valued functions on the interval $[0, 1]$ a maximal ideal? Extracting raster values at points using Open Source GIS? Battle of Hoth: how did the AT-ATs manage to disable the shield generator? (This question is related to , and was originally posted as an answer there, but it's not the same)    In , the Empire attacks Rebel Echo Base located in Hoth. The Rebels are alerted before the attack, and raise some sort of shield to prevent orbital bombardment of their base. The Empire is then forced to deploy land forces to first disable the shield generator, before destroying the base. Presumably, the Imperial forces are deployed using dropships.  My question is about how the Rebel shield generator works, and how the Imperials manage to bypass it.  I think the shield generator is something of a plot hole. At first I incorrectly thought it was a planetary shield (i.e. a shield around all of Hoth) preventing orbital bombardment, and also preventing any dropships (with their AT-AT payload) from landing, but I think : the  states it is an energy field around just an area of Hoth, presumably Echo Base:     VEERS: My lord, the fleet has moved out of light-speed. Com-Scan has   detected an energy field protecting an area around the sixth planet of   the Hoth system. The field is strong enough to deflect any   bombardment.   So my initial objection ("how did the Imperial dropships bypass the shield?") has been answered: they didn't. They landed outside the energy field to deliver the AT-ATs. But now I have another question: does an AT-AT have to walk inside the field to fire at the generator, or can it fire into the field from outside?  Maybe the field simply cannot stop matter, only energy weapons (therefore preventing orbital bombardment), in which case the AT-ATs would be able to just walk inside. However, the script also states:     LEIA: All troop carriers will assemble at the north entrance. The   heavy transport ships will leave as soon as they're loaded. Only two   fighter escorts per ship. The energy shield can only be opened for a   short time, so you'll have to stay very close to your transports.   So it's clear that the energy field is also capable of stopping matter, in this case troop transports and fighters. It follows that it should also prevent AT-ATs from walking through it. So the only way I can see the walkers disabling the generator is by firing into the energy field!  This would mean the field is strong enough to stop matter such as ships and fighters, and energy weapons used for orbital bombardment (and also the Ion Cannon the Rebels use as an anti-orbit battery: Leia also states they must lower the shield to use it), but not able to stop whatever energy weapons the AT-ATs use!  So how on Earth did Imperial Walkers manage to disable the shield generator? How can I copy a custom Dictionary on Word 2000? Why is my host name wrong at the Terminal prompt when connected to a public WiFi network? For three days straight, I have connected to the public WiFi network at my local library. Each day, I have seen a different prompt in Terminal. Here are some of the prompts I've seen:  zp-pc:~ russell$ mary-pc:~ russell$ normob05:~ russell$   I have check under System Preferences -> Sharing, and my computer name is "Russell's Mac". Also, I set the DHCP Client ID to "RUSSMAC" under System Preferences -> Network -> Advanced -> TCP/IP, but I still see the random host names at the Terminal prompt.  Why is my computer name changing every day? Integral of $\sin (x^3)dx$ $$\int \sin (x^3)dx$$ I have tried some substitutions, but I haven't reached the goal... Can you help me? Concurrent and Blocking Queue in Java Cannot delete files, nothing seems to work I am on Windows 7.  I have some files on my computer leftover from an old version of Photoshop.  (I think... I don't remember exactly where they came from, but they seem to be Adobe files.)  There are 124 of them in a folder, which I have named "KILL."  (I don't remember what the original name of this folder is, it's been on my comptuer a long time.)  These files seem to be absolutely undeletable, as far as I can tell.  I can move them around and change the name of the folder, but deleting them is out of the question.  I also can't move them onto a different hard drive or flash drive, I've tried that.  So, let me list the things I've tried first:   A whole bunch of different "unlocking programs."  Including: IObit Unlocker, Lock Hunter, FileAssassin, and Project Kill box.  What I use LockHunter I am told: "No processes locking this file or folder have been found."  All of the other programs I've tried give me similar messages, telling me that nothing is locking the files.  Yet when I try to delete the files using LockHunter, I am simply told "Cannot delete x."  No reason is given. Tried using cmd.exe.  Even when I run a command window under administrator, it won't even let me access the KILL folder, much less delete anything.  I also tried killing explorer.exe from the task manager, and then using the cmd window.  Still can't even access that folder. Tried using safe mode in combination with these other options, doesn't change a thing. Tried changing permissions of the files using the security tab under properties.  It simply says "not inherited."  It will not allow me to change a thing. I am definitely the administrator of this computer. Tried Disk Cleanup and Defrag.  I suspected that some files must be damaged or something, but Disk Cleanup wasn't able to find any errors.  Defrag didn't help.   So, let me just say that I am not a computer expert.  But based on all the things I've tried, I suspect that this might be some hardware problem?  It seems strange that these files don't seem to be used by any processes, and yet are absolutely undeletable no matter what I do.  Is there anything else I can try?  Has anyone had any similar experience, and have any idea why this might have happened?  EDIT: Interesting recent development.  As I have toyed with moving the folder around, I moved it to the Program Files folder.  Now that it's there, it suddenly CANNOT be moved nor renamed.  It is stuck there, apparently permanently, as a folder called "KILL."  How irritating. 155 GB in c drive used up. 50 GB used in minutes. Windows 7 My laptop has Windows 7 home premium. OS is installed on C drive. The C drive has some 155 GB but currently only 1.17 GB is free. I deleted contents of my download folder and moved the contents from my desktop and my documents. this freed some 50 GB. but within minutes it was full again. ran disk cleanup and gained some 2 GB. i checked size of all the folders ignored large sized windows and program files and program files (x86). Was baffled when users folder said 110 GB. went to my user folder and selected all files n checked properties it showed under 5 GB. So if i check my user folders properties it says 110 GB but if i check properties of its content its under 5 GB. BTW I am not using any anti virus program. Do you guys have any idea whats going on. Is my laptop possessed or something? :P Please help me out. How to change the date format? Presently the date is showing as mmm dd hh:mm:ss. Is there any way that I can change it to as per my liking.

Prove that $||x|-|y||\le |x-y|$ I've seen the full proof of the Triangle Inequality  \begin{equation*} |x+y|\le|x|+|y|.  \end{equation*} However, I haven't seen the proof of the reverse triangle inequality:  \begin{equation*} ||x|-|y||\le|x-y|. \end{equation*} Would you please prove this using only the Triangle Inequality above?  Thank you very much. Review overview shows two suggested edits for a long time, but the review queue is empty When I went to the review overview on Meta on 08.01.2015, 19:16, it listed two open items in the suggested-edits queue, however when I clicked on the queue, I was told that the queue had been cleared. When I went back to the review overview, however, the edits were there again.  Since the icons for recent reviews had not moved, I suppose that these were still the same two items waiting for review, and since phenomenon lasted for half an hour now, I would rule out  or  to be the reason for this.  After a while, the phenomenon ceased, with one new reviewer popping up in the icon list of recent reviewers.  I had not performed or skipped any suggested-edit review from the queue at that point.    A similar phenomenon occurred for several hours up to 11.04.2015, 11:05: The review overview showed two suggested edits and when I went to the suggested-edits queue, it was cleared. Sometimes, edits that I could review appeared, but two phantom edits remained. How to find out the variant of my Galaxy Nexus?
