load

Over time I've rolled my own formats for saving and loading object properties but on having to revisit this I'm wondering about using Delphi's own text DFM format. I know tha this is really an 'internal' format, but the reader for it now seems pretty well defined and it copes with all types of property. Has anyone any comments about possible pitfalls? I wouldn't really say that DFM is an 'internal format'. Sure Delphi uses it internally for forms and datamodules, but TReader and TWriter classes that perform streaming are publicly accessible and even documented. So they are clearly intended for

I am creating a server to monitor the online presence of clients on a webpage. There will be 80-100 000 (eighty thousand) simultaneous clients to monitor. I’m using .Net to write this. Clients will contact a (separate) server using JavaScript (on the HTML-page) to tell the server that they are alive/online. I’m considering one of two approaches: Persistent connections with keep-alive sent regularly. This will give me much higher precision on when clients disconnect and I don’t need to update memory structure (onlineinfo) too often because we know when client comes and goes. Additional benefits

Im curious about what the best way to load a rails partial with jquery. So far I have tried a solution not working: $('#imagecontent').load('/newsletters/_image_gallery.html.erb', function() { alert('Load was performed.'); }); Is the best solution to build a seperate action and/or controller for this and set up a route? Im asking because making the first solution work seems more easy, perhaps not so restful. Thanks. You should not be able to access Template files (.erb) from HTTP requests, this is very bad practice. I suggest you put them outside your web servers path and access them only

If one calls Assembly.Load multiple times does it cause any side effects? e.g. for (int i = 0; i < N; i++) { Assembly.Load(assemblyStrongName); // ....... } This loads the assembly one time doesn't it? I've checked with AppDomain.CurrentDomain.GetAssemblies() before and after and it seems it's loaded one time (as it should) but does it have side effects? In a long running server application (runs for months/years with no restart) does the above cause any issues? This loads the assembly one time doesn't it? Yes. The assembly gets loaded into the current AppDomain, and will only be loaded once

I need to dynamically load jQuery and jQuery UI from a javascript, then check if it has loaded and do something afterwards. function loadjscssfile(filename, filetype){ if (filetype=="js"){ //if filename is a external JavaScript file var fileref=document.createElement('script'); fileref.setAttribute("type","text/javascript"); fileref.setAttribute("src", filename); } else if (filetype=="css"){ //if filename is an external CSS file var fileref=document.createElement("link"); fileref.setAttribute("rel", "stylesheet"); fileref.setAttribute("type", "text/css"); fileref.setAttribute("href", filename)
