limit

问题 I'm running a java program as root on a linux machine. In order to increase the Max open files limitation, I added the following lines into /etc/security/limits.conf * soft nofile 1000000 * hard nofile 1000000 However when I check the running program by cat /proc/<pid>/limits , it still tells me that the Max open files is 65536 . Until I added another two lines into /etc/security/limits.conf , the Max open files could be changed to 1000000 root soft nofile 1000000 root hard nofile 1000000 I

问题 I've a div with text inside that is displayed using PHP & MySQL, the structure is like this: <div class="description"> <p> Here is a lot of text. </p> </div> I want to display a "Read more" link when the text inside the p-tag is more than 100 characters. I can display the "Read more" link with PHP like this: // strip tags to avoid breaking any html $string = strip_tags($string); if (strlen($string) > 100) { // truncate string $stringCut = substr($string, 0, 100); // make sure it ends in a

问题 I have 10,000 users on registrations table and want to limit this query to 3500 users from my application. But when I investigate the logs , sometimes it counts more than 3500. I can not understand why that query returns more than limit: select count(*) from registrations where (selectedtime IS NULL AND expirationtime < NOW() ) LIMIT 3500; I tried manually on DB and saw sometimes more than 3500 回答1: Your query only returns 1 row, which is less than 3500. If you want to limit the number of

问题 Right now I'm working on migrating a site from using an oracle database to use salesforce. For querying the data we are using the latest version of the salesforce rest API. Right now I'm facing a problem paginating results with an offset greater than 2000. I have seen quite a few questions on this topic but none of them seem to fit my problem. So Here are the restrictions I need to fetch the results on chunks of 20 records (that is the page size). I can't just get a bunch of results and then

问题 I would like to disable selecting more than 2 choice checkboxes, but I couldn't do it with my javascript code. How can I do this? btn.addEventListener("click",function () { var ourRequest = new XMLHttpRequest(); ourRequest.open('GET','questions.json');//json dosyasından sorular ve sıklar okunuyor ourRequest.onload = function () { pos = 0; counters = [A=0,B=0,C=0,D=0]; ourData = JSON.parse(ourRequest.responseText); renderQuestion(ourData); btn.innerHTML = "BAŞA DÖN"; } ourRequest.send(); })

问题 Even after setting tf.config.threading.set_inter_op_parallelism_threads(1) and tf.config.threading.set_intra_op_parallelism_threads(1) Keras with Tensorflow CPU (running a simple CNN model fit) on a linux machine is creating too many threads. Whatever I try it seems to be creating 94 threads while going through the fitting epochs. Have tried playing with tf.compat.v1.ConfigProto settings but nothing helps. How do I limit the number of threads? 回答1: This is why tensorflow created many threads.

问题 I know in most, if not all programming languages, integers, floats etc all have a maximum amount they can hold, either unsigned or signed. Eg pascal's int type can only hold up to 32768 ~. What i wanted to know was, what is the limit on python's int and floating point variables. I tried a little program to produce extremely large numbers, but i ran into no errors. Does it even have limits on how big these variables can be ? I looked in the documentation and couldn't find what i was looking
