HP Stream 7 Review: Things I Wish I Knew Before Buying 7 Inch Windows Tablet

1

HP Stream 7

Around a month ago, I decided to buy a cheap Windows tablet from eBay, HP Stream 7. This model is not available here in Indonesia. Here are several things I wish I knew about this tablet before buying it.

How much it really cost?
Well, if you are in America, you can buy it for $80 at Microsoft Store. But they can’t ship it here so I purchased it from eBay:
$100 – Normal price
$30 – Shipping (it took around 1 month to get here using USPS)
$10 – Tax, administration, etc
So in total around $140 (almost twice the price)
I also bought 32 GB MicroSD Card ($15), so I spent around $155 for this device.

Is it sucks?
Yes, kinda. But is it worth the money? (probably not)

How to Test Your Code in Multiple PHP Version (only $10/year)

0

cpanel-select-php-verWordPress is a Global CMS, with very minimum requirement to install:
PHP: version 5.2.4
MySQL: version 5.0

I’m sure most of us have better server configuration than the minimum. I think most hosting have at least PHP 5.4 installed. but as a freelancer, sometimes we get a client with older version of PHP in their server. And for whatever reason they cannot/do not want to upgrade to better hosting.

If you don’t have multiple PHP version in your server, you can always install multiple PHP version in your server and pollute your server with outdated script.

Or you can spent $10 and have a separate server where you can test your code for whole year.

$10 / year, that’s only $ 0.83 / month Read More How to Test Your Code in Multiple PHP Version (only $10/year)

How to Sanitize Image Upload?

0

Today I updated my plugin f(x) Favicon (no longer available, WordPress now have “Site Icon” feature), and I would like to share in how I sanitize image URL in the plugin uploader.

favicon-settingsWhy sanitize image upload?
Basically what we need is to make sure that the input is an image URL. So, we don’t want user to input other file such as document file, video file, mp3 file, etc.

And this is to make sure our plugin/theme working correctly. We also need to do this check before loading the file.

Wanted result:

<link rel="shortcut icon" href="http://siteurl.com/path/favicon.png"/>

Unwanted Result:

<link rel="shortcut icon" href="http://siteurl.com/path/some-random-file.doc"/>

Yesterday I wrote a WordPress Login Notification Plugin. And I use Anonymous Function (introduced in PHP 5.3) in the settings. It work well in my server but when I install it in my client site, the settings page is truncated even though my client use PHP 5.3.

settings-page-truncatedAfter some googling, I found that we cannot use $this in anonymous function in PHP 5.3, we can use that only in PHP 5.4 +. Thank god I didn’t get fatal error 🙂 Read More How to use $this in Anonymous Function in PHP 5.3

O God! sometimes I wish that there had never been a religion, because that which should unite mankind into one common brotherhood has been through all the ages a cause of strife, of discord, and of bloodshed. Members of the same family have persecuted one another because of the different manner in which they worshipped one and the same God. Those who ought to have been bound together by the tenderest love have turned with hatred from one another. Differences of Church, albeit in each the same word, God, is spoken, have built a dividing wall between two throbbing hearts. I often ask myself uneasily: is religion indeed a blessing to mankind? Religion, which is meant to save us from our sins, how many sins are committed in thy name?
