“Picked up _JAVA_OPTIONS” when no such environment variable exists

余生长醉 提交于 2019-11-28 12:41:23
This issue pertains specifically to Minecraft, but it is affecting all Java programs that run on my computer. It would seem that something is forcibly setting a _JAVA_OPTIONS environment variable. When I run my server, I have specified to allocate 4 GB of RAM to it with -Xms4G -Xmx4G in the startup batch file. However, when the server runs, It prints "Picked up _JAVA_OPTIONS: -Xms2048M -Xmx2048M" to the console, only allocating 2 GB. I have checked my system settings and there is no _JAVA_OPTIONS environment variable in the list. I do not want to add one, since that will also try to allocate 4

store multiple select option into a PHP array

若如初见. 提交于 2019-11-28 10:20:14
I have an selectbox list Is it possible to select multiple option: <select name="access_list[ ]" size="7" multiple="multiple"> <?php $res=mysql_query("select * from list" ,$conn); while($row=mysql_fetch_assoc($res)) echo"<option value=".$row['id'].">".$row['name']."</option>";?> </select> How do the values ​​that will be selected (select multiple values ​​together) can be stored in the array. I think that will do it for each order? Use name as name="access_list[]" without space. And you can get selected options with $_POST['access_list'] $_POST['access_list'] is array that contains selected

When (not) to abuse NSUserDefaults

只谈情不闲聊 提交于 2019-11-28 08:59:28
I wonder what the guidelines are for: 1 - how often I can read from NSUserDefaults 2 - how much data I can reasonably store in NSUserDefaults Obviously, there are limits to how much NSUserDefaults can be used but I have trouble determining what's reasonable and what isn't. Some examples among others: If my game has an option for the computer to be one of the players, I will use NSUserDefaults to save that boolean value. That much is clear. But is it also reasonable to access NSUserDefaults during my game every time I want to know whether the computer is a player or should I be using an

How to write custom data to the TCP packet header options field with Java?

别说谁变了你拦得住时间么 提交于 2019-11-28 06:36:41
As it is defined (see: http://www.freesoft.org/CIE/Course/Section4/8.htm ) the TCP header has an 'Options' field. There are a couple of options already defined (see: www.iana.org/assignments/tcp-parameters/) but I want to come up with my very own. (For experimenting/research.) How can I get Java to write (and then read) some custom data to the options field? Bonus question: if it cannot be done with Java. what kind of application can do this? (No, I don't really feel like messing with some kernel-level TCP/IP stack implementation, I want to keep it app level.) Thanks! JNetPcap is a library

How to change knitr options mid chunk

人走茶凉 提交于 2019-11-28 05:32:05
Hi I would like to change chunk options, mid chunk, without having to create a new chunk.. running the following code I would expect to get two very different size outputs, but for some reason this does not seem to be the case. Also the second plot doesn't plot at all...(it does when you change it to plot(2:1000)...but either way the second output is the same size as the first. both fig.width=7 . What am I doing wrong? Pls note the importance of 'mid chunk' the reason for this is that I would like to change the chunk options several times when running a function to get different outputs of

Android checkable submenu options

ⅰ亾dé卋堺 提交于 2019-11-28 04:31:35
问题 So I have a submenu that I have for an options menu item. I want a list of checkable entries that the user can select/deselect as many as they want. The only problem I can't solve is how to prevent the option menu from closing when one of the checkboxes is clicked. I saw the performShortcut has a FLAG_PERFORM_NO_CLOSE flag, but I'm not sure how to use that method. I've tried many things, but I'm confused on where the keyevent is supposed to come from or if this is even the right method I

Setting Default NetBeans Options (-std=c99, -Wall) for C programs

穿精又带淫゛_ 提交于 2019-11-28 02:32:46
问题 I have NetBeans 6.9 installed and working fine on Ubuntu Linux 11.10. My goal is to set compiler options like -Wall and -std=c99 to be used by default. Currently, I have to right click on my project -> Properties -> C Compiler -> Warning Level to " More Warnings " and add -std=c99 to Additional Options . This is obviously a pain when creating many projects, and I'm sure there is a way to make all of this the default . I found this thread which relates closely to my question. However, the only

Google Maps Api StreetView PanoramaOptions Point of View Setting from Lon Lat

本秂侑毒 提交于 2019-11-28 01:46:34
I've got a StreetViewPanorama identified by my Lat Lng coordinates. My Lat and Lng coordinates are not exactly on the road from which Google car took the picture, but they are in the center of the building that I want to see in StreetView's picture. So I have 2 couple of coordinates, and I think that it's possible to calculate POV degrees to obtain a correct shot of the building. What I need is how to get the Lon Lat of the point in which is automatically placed "the man", so that I can calculate the correct POV degrees. Vaughn My implementation of kiks73's solution.
