JQUERY issues with Google Chrome .ajax() doesn’t load

For the life of me I couldn’t figure out why my JQuery .ajax() call wouldn’t load in Google Chrome. Especially when it worked in Firefox, IE and Safari which I thought is based on the same WebKit browser. Anyhow, I found the issue to be in the data format AND having null vars.

$.ajax({
	type: "GET",
	data: "action=load=<? echo $php_load ?>&channel_id="+channel_id+"&color="+channel_color+"&login_id=" + <? echo $login_id; ?>,
	url: "index_feed_ajax.php",
	success: function(html)
	{
		alert("here");

		//hide the progress bar
		$("#loading").fadeOut();	

		//add the content retrieved from ajax and put it in the #content div
		$("#content").html(html);

		//display the body with fadeIn transition
		$("#content").fadeIn('fast');
	}
});

the first problem was the “data” formatting – the following example is incorrect.

	data: "action=load=<? echo $some_var ?>&channel_id="+channelId+"&color="+channelColor+"&login_id=" + <? echo $login_id; ?>,

data: should be in this format:

$.ajax({url: "index_feed_ajax.php",
      data: {
            load_feed: loadVar,
            channel_id: channelId,
            color: channelColor,
            login_id: loginId
        },
        method: 'GET',
		success: function(html){
			//alert("here");

			//hide the progress bar
			$("#loading").fadeOut();	

			//add the content retrieved from ajax and put it in the #content div
			$("#content").html(html);

			//display the body with fadeIn transition
			$("#content").fadeIn('fast');
		},                    

        error: function(HttpRequest, textStatus, errorThrown) {
        alert(textStatus+" - "+errorThrown);
        }
    });

You’ll also noticed that I changed the PHP vars. I ALSO found out if the php vars were null they would create errors in the javascript console.
I set some javascript vars with PHP values before these functions run.

<script type='text/javascript'>
	loginId = "<? echo $session->login_id; ?>";
	if ( loginId == null || loginId == "") loginId = 0;
	//alert ("header loginId: " + loginId );

	load_var = "<? $_SESSION['load']; ?>";
	if ( sessionLoad == null || sessionLoad == "") {
		loadVar = "some_value";
	}
	//alert ("loadVar: " + loadVar );

Mac OS X Mouse Hover Stops Working Logitech Wireless

So, I’ve encountered this problem a few times now where hovering over any menu or link doesn’t work and your Dock Zoom stops. I thought I’d share a solution because it’s REALLY ANNOYING!

First, make sure your batteries are charged. I find this problem begins when my batteries are low and I get stuck without mouse hover.

Next, try unplugging the Logitech USB wireless receiver and plug it back in. This helps most of the time.

If the unplugging and plugging in receiver doesn’t work, download the newest Logitech Control Center for Mac OS X

After installation of Control Center, you have to restart your computer. While restarting your computer, unplug the wireless receiver again for a couple seconds then plug it back in again.

After reboot, you should be back in action. Mac OS X Hover, Dock Zoom and everything else works again.

Good Luck!

MCrypt PHP5 Ubuntu Install

Ubuntu: PHP mCrypt Installation

mCrypt is an encryption program used on Linux systems.

To install mCrypt for PHP5 on your Ubuntu Linux system:

sudo apt-get install php5-mcrypt

Then restart Apache with:

sudo /etc/init.d/apache2 restart

I needed to do this so that  phpMyAdmin would have mcrypt available.

Removed Horde

./usr/local/psa/admin/bin/webmailmng --remove --name=horde

Tried Plesk Reconfigure All

./usr/local/psa/admin/httpdmng --reconfigure-all

but apache2 wouldn’t restart error, “Can not restart web server:

Finally, Plesk “Reconfigure Server” worked!

./usr/local/psa/admin/httpdmng --reconfigure-server

Not sure if removing Horde was necessary. Anyhow, I’m back in action and Apache2 can be restarted whenever I need!

View log files using GUI tools using the GNOME System Log Viewer

System Log Viewer is a graphical, menu-driven viewer that you can use to view and monitor your system logs. System Log Viewer comes with a few functions that can help you manage your logs, including a calendar, log monitor and log statistics display. System Log Viewer is useful if you are new to system administration because it provides an easier, more user-friendly display of your logs than a text display of the log file. It is also useful for more experienced administrators, as it contains a calendar to help you locate trends and track problems, as well as a monitor to enable you to continuously monitor crucial logs.

You can start System Log Viewer in the following ways:

Click on System menu > Choose Administration > System Log:
View log files in Ubuntu Linux
(The GNOME System Log Viewer)

Note you can start the GNOME System Log Viewer from a shell prompt, by entering the following command:
$ gnome-system-log &

thoughts on logo design

First we have the discovery phase. At this point in time we find out what personal brands client trends towards. What car does he or she drive, prefer, buy and really like. What restaurants do they frequent and enjoy. In this instance we would find out specific brands he or she purchases for their business. Also, what logos can they visualize in their head. In doing so we help identify the brands and styles this individual enjoys. This helps guide us to making a logo that represents our client. We also discover the the intricacies of the business operation and use these ideas as keywords in developing a logo.

After discovery we begin the design process:

8/4/2/1 Logo design process

8 unique logos are delivered for round I
We ask the client what elements they like from each logo and refine for round II.

4 logo revisions for round II.
Again, we get feedback and revise these iterations.

2 revisions for round III
more feedback and fine tuning the designs.

1 final design

Time Frame: This really depends on the speed at which we get feedback for each phase. Overall time should be from 2-4 weeks.

Format: The logo will be a vector drawing which will allow for scalability from business card small to billboard size large.

Some of my thoughts on good logo design. You want to make sure the logo works well “small” and in black and white. Think of some popular logos; Apple, McDonalds, FedEx, Nike, Target and VW, to name a few. All of these logos started out more complex then their current iteration and worked towards simplicity. What these companies have down over time is simplify the design. All of these examples work well with 1 color, which you have to keep in mind for printing and reproduction. In my opinion, what makes them successful is the simplicity. Anyone, regardless of art background, should be able to look at a logo for 3 seconds and be able to draw the basic concept of the logo. Your brain should be able to process *all* the elements of a logo by simply glancing at it.

Plesk Ubutnu Qmail runs in shell but not in Plesk Services Management

the weirdest thing happened…

/etc/init.d/qmail restart

wouldn’t give any errors.

however, trying to restart with plesk services management and the service would never start. this is because plesk checks Qmail with:

telnet localhost 25
AND
/usr/local/psa/admin/bin/mailmng –status-smtpd

hmmm, qmail is running with the status check but not listening / bound to port 25. what controls this on ubuntu? xinet.d…

turns out after upgrade, my /etc/xinetd.d/smtp_psa file was empty!!! i created a new one

stmp_psa xinet.d file:

service smtp
{
id = smtp-localhost
socket_type = stream
protocol = tcp
wait = no
disable = no
user = root
instances = UNLIMITED
bind = localhost
server = /var/qmail/bin/tcp-env
server_args = /var/qmail/bin/relaylock /var/qmail/bin/qmail-smtpd /var/qmail/bin/smtp_auth /var/qmail/bin/true /var/qmail/bin/cmd5checkpw /var/qmail/bin/true
}

after saving smtp_psa file i restarted xinet.d and QMail is working again…

    • Corey Green you forgot the random…somewhere in there is a random multiplier that makes the computer really fast when you don’t care and really slow when you need something.

    • James E O’Loughlin Sorry Ron. Windows 98 and dos 3.1 are about the last time I remember MS being zippy. Pretty much everything feels bloated and sluggish now with far too many options. It’d be nice to have a trimmed down core app/is and you add packages you want. Like Linux!. Maybe I just need faster hardware. Or, maybe my computer’s mood ring turns to vomit color when I open an office app lately cuz it’s ……

    • Dan Miller It’s Microsoft’s job to ensure than any hardware advancements are nullified by an operating system that needlessly cripples the hell out of it. Windows 3.1 on a 386 = 95 on a 486 = 98 on a Pentium = ME on a Pentium 2 = XP on a Pentium 3 = Vista on a Core2 Duo = 7 on a Core2 Quad. Nothing ever gets any faster because Microsoft has always been about making it slower by dumbing it down and making it “pretty.”

      Hey James, You can always disable features to reduce the footprint of the OS. This is even more true of the Server OS’s. I noticed a couple of the other commenters here threw out a bunch of generalizations that are way over used and clich…e’. 12G of RAM in an Office machine – sounds like a case of more dollars than sense. Windows 7 is faster – there is imperical evidence to prove this. I don’t want to get in a shouting match here, I know everyone has there preferrence and I am not here to change it one way or the other, however I would be happy to assist you in determining why your PC is sluggish or feels unresponsive.See More

      Sorry, Ron. I’d love for you to help but I honestly gave up on Microsoft in the late ’90s when I was using an Amiga desktop, maintaining VAX and IBM RS servers for Miami University. I was also forced to maintain client Windows boxes which …were always a mess for a multitude of reasons. I prefer the X OS’s now; Unix, Linux and OS X. If I’m forced to run windows I use Sun’s VirtualBox. if anything goes bad, I just delete the Windows image file and reinstall the system. My initial post was me venting about opening Excel spreadsheets when a client sends them. In fairness, the comments above are legit and not cliché. I know Ted slammed 12gb of RAM in his box because he does some complicated algorithms and data processing in Excel. I think he should find some grad student to write apps for his school’s parallel or cluster servers and get screaming fast CPU cycles. Dan’s a smart cookie as well, he owns a successful IT consulting firm which I believe helps Windows peeps out. I won’t take anything away from your knowledge or expertise of Microsoft products. You most likely have you and your clients boxes flying. I think anyone with an in depth knowledge of any OS can keep their box and servers optimized, running fast and virtually free of issues. I just prefer to stay clear from everything MS. which constantly reminds me of viruses, scans, drivers and bloat…See More

removed the cron job – i’ll see if this stops the emails. I’m afraid that the QMail cron or something is calling drweb. we’ll see if this works.

root@blue:/home/primax# crontab -r -u drweb

this will remove the cron job for drweb…

finally *might have* figured out how to get rid of the annoying drweb cron emails, “/bin/sh: /opt/drweb/update.pl: not found”

solution found here

Log in as root (or you can use sudo) and open /etc/drweb/drweb32.ini:

Look for:
CronSummary = Yes

And change it to:
