I was able to construct a string with length 2^28 - 1 , but when I tried to create a string with one more char, Firebug showed me the "allocation size overflow" error, meaning the string must be less than 256 MB. Is this the same thing for all browsers, all computers, all operational systems, or it depends? I created the following snippet to find out the limit: (function() { strings = ["z"]; try {

I am doing research this summer which involves me getting a program written in about 1980 working again. It is written in Fortran 77. I have all the code as well as some documentation about it. In its current form it I am receiving a "IEEE_UNDERFLOW_FLAG IEEE_DENORMAL" error. My first thought is that this code was meant to be developed under a different environment/architecture. The documentation

I could do this: p1 = subprocess.Popen(["mmls", "WinXP.E01"], stdout=subprocess.PIPE) result = p1.communicate()[0].split("\n") for line in result: script_log.write(line) script_log.write("\n") p1 = subprocess.Popen(["stat", "WinXP.E01"], stdout=subprocess.PIPE) result = p1.communicate()[0].split("\n") for line in result: script_log.write(line) But that really isn't very aesthetically pleasing

Therefore, if someone looks back to a previous message, I need to be able to convert the timestamp to what the time was relative to what the timezone was then. How do I get what the timezone was then? For example, on September 3, 2012 the timezone is PDT. The current time offset is -0700. I send a message at 9:06. The time UTC is 16:06. I come back to this message December 1, 2012. The current timezone is PST. The current time offset is -0800. I look at the message I sent on September 3, 2012. If I were to

I'm trying to fire up logstash in a Docker container but when I mount the config file as a volume, it doesn't seem to find it. Interestingly, if I start up the container with bash, I can see the config file in there and running the same command as what docker would, it works.

Everything works fine, except when I call showText on a PDPageContentStream where I previously set the font with out.setFont(textState.getFont(), textState.getFontSize()) (see the INFORMATION log) and the font is ComicSansMS or ArialBlack. textState is (a clone from) the state from the previously read document. Writing text with Helvetica or Times-Roman works fine. INFORMATION:

I'm using a command like so: signtool.exe sign /fd sha256 /f "key.pfx" "app.appx" And from this, I get: SignTool Error: No certificates were found that met all the given criteria. What "criteria" am I not meeting? This is only for testing so these are self-signed certificates. I've tried importing the key and then signing it, but it always results in the same error. How do I fix this? 回答1: When getting this error through Visual Studio it was because there was a signing

I want to stop the integration after all the states reach their desired values (or atleast close to them by $1e{-3}$). How do I use event function in matlab to do this? (All the help I have seen are about 1 dimensional states) PS: I know for sure that all the states approach their desired values after long time. I just want to stop the integration once they are $1e{-3}$ within the desired values. 回答1:
