I am using codes on my sites that I have never used before just for the layout and music player.
The page/audio player works perfect on desktop and android devices if I use this page: http://chancetrahan.com/1abcd.html
The player only works on desktop versions if I use the index file at http://chancetrahan.com
I have followed the site speed up suggestions on pagespeed insights and have gotten it to work on desktop, but I just realized it's not working right, and not showing up right if I view from android browsers.
I'm not sure if it's broken because I compressed the .js and .css files when I transferred them to my site or not, but that is what I am thinking might have happened.
I noticed that when I remove the FB ROOT from the code, it breaks the music player, I have no idea why the music player uses FB ROOT, but it does, I'm not sure what rollups are, but it also says that common.js is running twice.
I have stripped down the code to the bare bones trying to replicate this layout/template/theme with minimal code use, and a speedy response. You might not be able to see some of the code because I am using cloudflare, but I would be happy to use TeamViewer to go over this and kind of get some insight form someone who understands this code.
If you could help me figure this out I would be really appreciative for all the help I can get. Thank you for your help and advice!
It's very common to break javascript files when trying to lower your pagespeed scores. If you're using Cloudflare, test it on development mode and see if it works. Often times rocket loader will cause a problem.
I hope you have a backup of the javascript files before you minified them. If you tried to minify code that was already compressed, there's a very high chance that you broke it.
Further, pagespeed is not as big of a deal as you'd think when it comes to SEO. I put a lot of development hours into making a Wordpress theme from scratch that can get a 100/100 Pagespeed score. It helps, but not a crazy difference in terms of search engine rankings. It's more about just being nice for your users.
Another thing to mention, if you're concatenating your javascript files, first check if your server supports HTTP/2 as this will actually make your site much slower if it does. HTTP/2 is the new version of the SPDY protocol which requires HTTPS, and will quickly and efficiently deliver many resources at once without the need for concatenation.

So there's this simple game, http://www.zigzagphilosophy.com/, that I've enjoyed playing around with every once in a while for a few years. However, I recently learned it was written in Adobe Flash, meaning its unplayable on most browsers currently and will be completely unplayable in a few months. Since it's a simple game, I decided I would try to port it to JavaScript by looking at its source code. However, the file index.swf that makes up the game simply downloads to my computer, where it cannot be opened by any means. How would I go about opening that file and being able to read the source code in a compiled form (e.g., looking like lines of code instead of just data)?
i have very little experience with javascript, though i read through the comments on your question and as you don't mind rewriting it yourself, i can recommend an swf decompiler for you. it's called jpexs flash decompiler and is accessible here. pretty sure it requires java and the gui looks pretty crappy but i can tell you from personal experience that it works well.
you can extract audio, images, basically whatever's there, as well as exporting to an fla or exe file.
i'm sorry i couldn't be of any more help than this, but i hope what i've written is at least useful :)
Let me preface by saying I have no idea of what I'm doing. I've inherited a system from a contractor that we hired to do a job. I'm not significantly familiar with web development, and I have no idea how the magic voodoo was configured or really works. If you're going to reply, be patient, and assume I don't know jack about what you're telling me - please don't leave anything "for the reader to figure out." I'm embedded by trade and would rather bang bits than develop back end code for a website.
Server is running on an embedded Linux platform (basis is OpenWRT). The core is Lua/Luci, but there's a plethora of HTM files that utilize both HTML and JavaScript.
What I want to do seems really, really straight forward, but I can't seem to make it work: There is a file in /etc that I want to be able to download from the server to the local machine. Needs to work with IE, Firefox, and Chrome.
I would have loved something like:
download
But it doesn't work for files outside the subdirectory area that lua/luci knows about (i.e. I can't "../../../etc/file")
I've tried several different things, but the biggest issue is I can't seem to get the lua/luci stuff to recognize anything new in the same directory that contains some of the htm files, nor anything from the server's root directory (e.g. /etc/file). Usually what I do goes back to the home page or displays:
No page is registered at '/admin/talon/file'.
If this url belongs to an extension, make sure it is properly installed.
If the extension was recently installed, try removing the /tmp/luci-indexcache file.
(And yes, I clear the cache before I reload the page).
I'm OK with creating a symlink to the /etc/, but that hasn't been fruitful, either - mainly because I really don't know what kind of magic the lua service is doing to find the existing files.
I'd prefer for the solution to be in just HTML and JavaScript.
Yes, I've looked around for a basic solution, but either the questions want to do more than just download, or there's not enough information for me to figure out what is supposed to be done.
Please post a full solution, not just snippets.
I was able to figure it out based on some other code within that same source. It worked on one page, but not another. Not sure why - just more sorcery. Had to work within the LUA scripting language to get to the file I wanted; HTML was straight forward. If I knew what the magic thing was to make it work, I'd post the actual solution, but I think the solution is somewhat unique to how the original developer put things together, so it wouldn't be useful to anyone else.
I have been developing phonegap applications that need to make updates oftenly. The problem is pushing a new ipa to iTune Store take too long. So, I uploaded the application source codes(minified javascript) to my server and download it from application and "eval" the minified js files. But i feel using eval has limitations and also not the right way. So, can someone tell me the right way to accomplish this.
thank you so much.
I'd love to have something like this as well. You're already ahead of me w/your eval() approach - but I'd have the same concerns as you there. Here's what I'm aware is out there on this topic - hope this helps?
IdeaPress(?)
I just recently caught wind of this one - not sure how feasible but it claims to do exactly what we'd like. I have to say the main site looks a bit flaky but I will definitly be checking this out to see if it's feasible or not.
HockeyApp?
HockeyApp (possibly dead-end now). I thought there used to be a pretty clear solution for PhoneGap devs to integrate the HockeyApp API/feature set with their mobile apps but a recent Google search on this is turning up much less than I would think - so maybe it's a dead end now? http://goo.gl/GQOv5o

This requires more work and I haven't pushed far enough yet to see if it truly could be a means of updating the app post-app-store-deployment. But based on what I've read if you're just updating code for your WebView you shouldn't have to worry about App Store rejection or anything. Related tutorial
Testflight App Testing (Apple)
I haven't gotten to play w/this yet but sounds like it could be promising for at least the beta/testing phase of development. I, like you, need a solution for end-users, not app testers, but I'll still be looking into this soon as it might replace me having to maintain my own over-the-air app installs for the best/testing periods.
I have a small web application I've been working on and the amount of Javascript is starting to build up. I was wondering what the best practise was ( if there is one) as to when to load/reference your javascript. All at once at the beginning OR as its needed dynamically?
I know how to add the Javascript references dynamically through ajax when parts of my site are loaded and require it?
I hope this question makes sense, I'm still new to this.
Many thanks.
It really depends on the size of your JavaScript. It is better to load one 50kb file at once than having the browser request 50 x 1kb. First of all I'd recommend minimizing the JavaScript sources and see where that goes.
A great tool for benchmarking your site is YSlow which also suggest some improvements you could make. Please do not try to solve everything YSlow criticises as some of the recommendations only make sense for really big sites. (e.g. you are probably not going to need a distributed CDN, etc.)
For JavaScript minification I have very good experience with the Closure Compiler from Google.
I am getting extremely slow load times and before any action is taken I was wondering if there was an easy way to test to see if it is because of the ISP or the coding of the site.
We currently have a T1 going to two mirrored servers, so I don't think the ISP is the issues, we only have a few users on at a time.
The website is: http://www.designfacilitator.com/v20/Default.aspx?login=true&ReturnUrl=%2fv20%2fDefault.aspx
Is there a definitive test to determine where the problem lies? or any advice would be great.
Thanks!
Do you notice high load times if you run the webApp on a intranet?
If it's the Coding it'll go slow on a local deployment load-testing as well - but to know for sure you wanna turn on asp.net tracing and have a look at load times and latencies through the trace viewer (or directly in the pages). The figures will jump to the eye!
The definitive test you're looking for would be to access the website from somewhere else with a different ISP (if it's still slow --> there you go), but this is a fairly obvious suggestion so I am probably missing some element here.
Anyway, Experience-wise, it's almost always the Coding :)
I loaded the site in the Firebug Net panel and the initial HTML loads in less than a second, so it doesn't look like a really limited server or bandwidth situation. Still there is a lot you can do to speed up the page.
First get Firefox (if you don't have it), then install Firebug (getfirebug.com), then install YSlow (from firefox plugin site) which will analyze your page and give you recommendations. There is also a plugin there from Google called Page Speed that does some of the work for you. It'll optimize your images and combine the JS into a single file.
There is a 'net' tab that shows you at what point each file included in your page is loaded and how long it takes. This can help spot problems. Yslow will also give you specific recommendations.
From the quick look I saw of your src, you need to move your JS files to the bottom of the page, and I think you could combine them into fewer files for even more speed.
Remember, the trick is to only load the smallest amount of code required to make your page work. Then, once the page is loaded there are a number of ways to load additional code as you need it.
Keep an eye on Steve Souder's blog (http://www.stevesouders.com/), he's pretty much the guru of front-end performance.
