Anyways, See the video below. P.S I’m the black power ranger!

MySQL has an in-built query cache which caches the results of SELECT queries, however we need to enable this functionality before MySQL can use it as by default its turned off. The logic behind this is that frequently used database queries will run much faster, mainly because the data resultset will be read from the cache instead of having to run the query again (*Cool Beans*). The MySQL query cache is available from MySQL 4.0.1.

So whenever tables in the database are modified the relevant entries in the query cache are flushed so you can be certain that even with the query cache enabled only up to date data is returned. Now that sounds great, so lets enable this on our MySQL Server!

Let’s get cache’in!

First off we need to make sure query cache is disabled, So we need to see what parameters are set, by running the following query in MySQL:

SHOW VARIABLES LIKE '%query_cache%'

Below is an example result for the above query, This shows that the query cache engine is available, but the query cache size is set to zero and therefore nothing will be cached, and the query cache engine will not actually be used! So lets get it enabled!

+------------------------------+---------+
| Variable_name | Value |
+------------------------------+---------+
| have_query_cache | YES |
| query_cache_limit | 1048576 |
| query_cache_min_res_unit | 4096 |
| query_cache_size | 0 |
| query_cache_type | ON |
| query_cache_wlock_invalidate | OFF |
+------------------------------+---------+

If you want to, It is possible to set the query_cache_size variable without actually restarting the MySQL server, by running the following SQL query.
In this example, we are enabling a 50MB query cache.
SET GLOBAL query_cache_size = 50*1024*1024;

Now Running the following line again to see what our server is running at.
SHOW VARIABLES LIKE '%query_cache%'

Output:
+------------------------------+----------+
| Variable_name | Value |
+------------------------------+----------+
| have_query_cache | YES |
| query_cache_limit | 1048576 |
| query_cache_min_res_unit | 4096 |
| query_cache_size | 52428800 |
| query_cache_type | ON |
| query_cache_wlock_invalidate | OFF |
+------------------------------+----------+

Great! We’ve now got 50Mb of cache availble in MySQL in our Memory. However with this method, the next time the MySQL server is restarted the setting will be lost and query cache will no longer be used. So ideally we need to look at how to make the change permanent, No problem!

Setting it in the MySQL config

Setting the MYSQL query cache size in my.cnf

In order to make the query_cache_size setting permanent the MySQL server configuration file must be modified to enable this from mysqld startup. These settings are stored in the mysql config file which for those of you that dont know, is called “my.cnf”. This file is typically stored on a Linux system at /etc/my.cnf or sometimes at /etc/mysql/my.cnf (Ubuntu/Debian based distro’s). If it’s not at either of those locations you can try running locate my.cnf or find / -name my.cnf, although note the latter will take a while if you haven’t run an #updatedb command for a while.

To enable the query cache with a 50MB query cache in MySQL you need to add the following line to the my.cnf file.
Be sure to add it under the [mysqld] section otherwise it won’t work.

query-cache-size = 50M

I hope that helps anyone who is seeing stupid amounts of slowdown with their MySQL server.

I’ve been following the feed and posts on facebook for some time and some of my MTB mates (Phil, Dale, Dim, Dean, Eddy, Adam, Harry and Kate) decided that they wanted to rent out the park for 12 hours. So they booked it one saturday night from 9pm till 9am! Cheers for to the Doncaster’s Northbridge Skate Park staff for being awesome in letting us do this as it was awesome!

Anyway, I created a small short video of the night, A lot happened and I didn’t records hardly any where near as much as I had originally set out to do! However we did have fun (including the hours worth of digging for Harry’s phone in the foam pit practicing his parkour!) I also took a stack of photos, but I’ve only chosen a few to publish, I’ve added these onto the end of the video, so be sure to watch it in HD!

If anyone else is thinking about hiring this skate park (northbridgeskatepark.co.uk) both myself and all the lads in the videeo highly recommend it! The facilities are great, and the owner is sound! Anyways Enjoy this short video.

Back when Google Apps launched (Yes I was there) They allowed you to signup for an account for your domain, They also gave you the allowance of 150 users per domain account, Yeah seriously 150 accounts!

But when they started to get bigger they realised spammers and users where grabbing these account and using them rather than paying for the Google Apps Business accounts. So Google slowly started to drop the user allowance down from 150, to 100, then 75, 50 then 25… We’re now at 10 and although thats nothing in comparison to the origianl amount that they first started with, its a massive amount given that most of us would like a brilliant email service, as cheap as possible!

I’m a massive Google apps user, I use it for myself, my clients, and my work. It’s something that has taken the problems away from email hosting as you can use that time else where learning other things. I believe that this is one of the reasons that google too supply you with the free Google Apps option.

How do I get a Google Apps Free Account?

Right, now down to business! What you’re getting is Gmail, GTalk, GCal, and Gdocs but not branded as Google. You get these on your own domain!
This post explains how to setup the free Google Apps Standard for your domain.

Step 1

Go to Google App Standard here (Google Apps Free) you have to add the domain.

Step 2

Choose custom setup click Go Custom button.

Step 3

Now we need to verify the domain owner as you!

Step 4

You can verify the domain a couple of ways, the quickest I find is by uploading a HTML file with specified files name.

Step 5

The Other way of verifing your domain is to include a set META tag in the domain’s index page.

Step 6

After verifing your domain the following success message will be displayed.
.

Step 7

Now we start creating some email accounts!

Step 8

Go to Organization & users tab and click “Create a new user” button and you can create a new email address.

Step 9

Once done, a success message will be dislayed.

Step 10

If you want to look at a current list of users you can click the “Organization & Users”

Step 11

As standard Google automatically provides you with a generic URL for accessing your Google Mail, however we can change that! Click change url and setup a custom url, Something like “mail.yourdomain.com” is probably ideal, however you can have anything you like.
Google Apps Standard for Free.

Step 12

Here’s where you choose your custom URL.

Step 13

Now we have to modify your domain’s CNAME records with the changes required for the custom URL and Email setup.

Step 14

Open a new tab login into you domain provier site like Godaddy, Bigrock etc, Go to the domain DNS settings and add mail CNAME points to Google server ghs.google.com
Open up another web browser, Login into your domain provider (I use http://123-reg.co.uk) Buy the domain if you don’t already have one however you should do if you’re at this stage!
Go to the domain’s control panel, and click Edit DNS. Now we need to add the “mail” CNAME to point to Googles server hosted at ghs.google.com and the following MX records too for the email to work.

Step 15

Now back to Google App page go to Domain settings tab click Appearance upload your logo
We now pop back over to the Google Apps page, go to Domain settings in the tab menu, and click Appearance, From here we can upload your custom logo etc, Which will take away some of the Google branding, Awesome!

Step 16

Now we’ve done all that, we can add our email account settings to our email client, However I’ll link you to the google tutorials for those!

I hope that helps someone out, Enjoy!

So I’ve been playing about and I’ve managed to get my QuickCam working on Windows 7 64bit fairly easily.

Firstly, you need to gram the right drivers, I’m pretty much only going to link to the 64bit drivers on this post, so if you need the 32Bit ones you will have a do a little digging first (Sorry).
Grab this f Logitech Quickcam driver for x64 vista (Yes i know its vista but we need this file.) from here (qc1051enu_x64.exe).

Once you’ve downloaded that you’re going to need a extraction program, like 7zip or WinRAR. I personally use WinRAR, so what you need to do is as follows.

Navigate to the location of the qc1051enu_x64.exe file, once you have done so right click the file, and you want to extract the contents to your PC. The reason we do this is because Windows 7 wont allow us to run this Vista installer, so we need to extract the contents of it out.

Once this has done, a new folder will apear next to this, called “qc1051enu_x64″ Inside of that folder will be the following files.

Navigate to the following folder, “qc1051enu_x64\Drivers\x64\PRO64\” (Note 32Bit version will differ slightly however the stucture is very much the same.

Once you’re in that folder there is a file named “lPRO64v.inf” you need to open this file now with a text editor. Once you have it open you will see alot of strings etc. What we need to do is find
the string “08bd” without the quotes, and replace this with the string “08b4″ (also without the quotes). Once you’ve done that, save the file!

Now we just need to install this new modified driver on our machine, so the quickest way is GO to the divice manager, (Right click “Computer” in the start menu and click “Manage”) then navigate to the “Device Manager” Then right click the unknown device which should be your webcam.

Once you’ve done that, you need to click “Browse my computer for driver software”.

It should then ask for your location of the files, You need to adjust this to the location to which you downloaded the files to, It should be the same as mine if you’re using x64 and extracted your driver “qc1051enu_x64″ to the downloads folder. If not locate your folder.

Then click next, and now you should have a completely working Logitech Quickcam!

I hope thats helped some else out out, as It’s taken me a while to figure this one out, However I do think it would be a massive help to someone trying to get the Logitech older camera’s working on windows 7.

If anyone has any comments or questions then please dont hessitate to ask in the comments section below.
Thanks! Dan.

First thing I did was restart the phone, however I quickly realised that the time and date on the iPhone where massively out from the current time. This was due to the phones charge being completely lost (because of innactivity) and not holding any batterly life for the clock to keep the time correct. So after I did the following step everything worked fine again.

Here’s a quick youtube video on what I did to fix this iPhone error, Its quick short and simple and I hope this helps anyone else out with the same issue!

However over the past 10 years the term “SEO” has been aimed at the wrong target, and thus spawned the “SEO Guy” Job, I’ll explain what I mean.

These “SEO Gurus” are the guys who hack the page to get the poor search engines to list the content top and not for the benefit of the users, So 7 times out of 10 the content is probably not even relavent! This I have always seen this method of SEO “hacking” as wrong and Google too now agree’s.

Infact Google wants the users to be the targets of the terms and content and not the search engines algorithm. This in my opinion is where it should have always been aimed its just alot of people have been so caught up with the play of the “SEO” buzz word that they’ve missed the point entirely!

To anyone that knows me personally my theory has always been if you can’t write some good informative content, then your site won’t rank as well as you need it to, but if you do write good content and you include the correct tags for this content and it’s correctly coded from day one, you won’t ever need to buy SEO services from anyone EVER, as it will ranks correctly for the content you have hosted!

Now Google has released a video with the way in which they are now looking for genuine content and exactly as I have described above they’ve backed up everything I’ve been saying for the last serveral years. God bless Google!

Anyway have a watch I’ve embedded the video below. Enjoy

Editors Note: My intentions of this post is not to offend anyone who is in the SEO, or Marketing Profession as this is just an opinion that I’ve had for well over 6 years now. However if you do feel you need to comment to air your views and/or defence (and I always love to hear other peoples opinions), then please do so in the comments below.

Thanks, Dan Cunningham

I so very much really want one of these, and Im sure you will too when you see the pictures below.

It looks just like the classic amp, but the Marshall Fridge is a 4.4 cubic foot refrigerator/freezer perfect for keeping your beer and pop on ice.

Promotional Video

So how many of you want to rock out your office with one of these? I know I do!

I took it upon myself (with some advice from a few friends) to actually write some new code and create this archive. At the top of this page you will see a “Resources” link. Inside that page is an archive of everything I’ve tweeted with a preview of the site I found it upon. If you click the URL or the Preview then you will go directly through to the original resource. So for those who follow me on Twitter, you can just visit that page from now on rather than having to favourite every tweet.

How it works…

It’s really self explainatry, but basically I make tweets to other design and development resources that I find and read daily online.

I Tweet said resource:-

After the tweet has been made, My site instantly creates the page of the URL I tweeted, giving you a preview of the said resource origin page.

Then just click the link or the preview shot of the resource site and you’ll get the original resource.

I hope that helps everyone!

“Can You Feature My Resource?”

Sure, If you’ve created something cool, possibly unique or even free, Let let me know! I always love to see new things so I’ll definately take a look. If it meets the critera I’ll tweet it and feature it in the resources archive too.

So drop me a message either on twitter or via the contact link in the header of this page.

Regards,
Dan.
