			<content:encoded><![CDATA[<p><a href="http://www.qianqin.de/wp-content/uploads/2012/01/watch.png"><img class="alignnone size-large wp-image-747" title="Kisai Optical Illusion Watch" src="http://www.qianqin.de/wp-content/uploads/2012/01/watch-530x348.png" alt="" width="530" height="348" /></a>I haven&#8217;t worn a watch for years now, relying on my cell phone to catch a glimpse of the current time. But when Tokyoflash released their <a href="http://www.tokyoflash.com/en/watches/kisai/optical_illusion/">Kisai Optical Illusion watch</a>, I had to buy it. I already loved the concept and now, I am the proud owner of the watch. The nice guys from Tokyoflash even offered me a discount since they&#8217;ve  been using my qTranslate plugin on their site. Unfortunately, I ordered before the discount code could reach me.<span id="more-746"></span></p>
<p>As you can see, I ordered the silver+natural lcd model because it looked the best in my opinion. So I was really excited when the small Fedex package arrived just 3 days after my order. When I took the watch out of the package, I noticed quite a lot of dirt inside the scratch-resistant protection from the manufacturing process. But the dirt all stuck to the foil when pulled off and no scratches were on the watch, so I guess that&#8217;s not a reason to complain.</p>
<p>After unpacking the package and adjusting the wrist band length, I began to set the time. There, I encountered a little problem I didn&#8217;t expect this watch to have. It doesn&#8217;t support 24 hour display format of the time. Here in Germany, it is very common to say 15 o&#8217;clock for 3pm. But oh well, I can live with this minor handicap. The watch itself looks very nice on the arm. From the pictures of the Tokyoflash site, I&#8217;d expected the watch to be too thick, but on the arm, it look just fine. It feels a little heavy, but that&#8217;s probably because I haven&#8217;t worn a watch for so long.</p>
<p>You can clearly see the complex LCD with all the elements, which makes reading the watch much harder than the images from the concept. I suppose I need much more practice to get used to the segments. It is easier than those sample images from the Tokyoflash website though. So except for the little segments, the four touchscreen areas also distract a little from reading the time. The touchscreen is not that sensitive if you&#8217;re used to touchscreen phones. You will need to hold you finger for a second to make sure that the watch will react to it. On the other hand, it is probably good that it won&#8217;t interact to fast screen wiping gestures.</p>
<p>The last feature to test is the EL back light, which works just as intended. All in all, the watch is really nice. Even with the downsides, it is definitely worth the money. The uniqueness and no physical buttons at all are just great!</p>

			<content:encoded><![CDATA[<p><a href="http://www.qianqin.de/wp-content/uploads/2011/10/overview.jpg"><img src="http://www.qianqin.de/wp-content/uploads/2011/10/overview-150x150.jpg" alt="" title="Overview of all changes." width="150" height="150" class="alignnone size-thumbnail wp-image-728" /></a>My girlfriend has a Sony Vaio VGN-C2S/P notebook from 2007 and it is getting old and slow. So her question was, upgrade or buy a new one? Well, the Vaio was build with 4 years old tech, a Intel Core 2 Duo 1,6 GHz Dual core processor, 2GB of RAM, a 80 GB hard disk and only 2 USB ports. You can get a notebook like hers for €300 these days, but for a true performance enhancement, one would at least need an Core i3-2 or i5-2 processor with 4 GB RAM and 500GB hard disk, meaning at least €500. That&#8217;s not very cost-effective considering her old notebook still works perfectly, so I decided to upgrade it instead. Like with her <a href="http://www.qianqin.de/2011/09/28/high-waf-inductive-charging-mod/">Samsung Galaxy S</a>, the only condition is that no changes should be visible.<br />
<span id="more-726"></span><br />
First, I listed all changes needed:</p>
<ul>
<li>faster than a current €500 notebook</li>
<li>More USB ports (she has a wireless mouse and a wireless keyboard, which eat up both of her USB ports and make it impossible for her to plug in anything else)</li>
<li>3G HSPA Internet for browsing the web everywhere (tethering is for geeks eh?)</li>
<li>as cheap as possible</li>
</ul>
<p>Let&#8217;s start with the first problem: A computer is always as slow as its slowest component, which in a notebook&#8217;s case is the hard disk. A spinning 2.5&#8243; hard disk is slow, so that needs to be swapped for a SSD. As SSD are incredibly expensive, only the system partition should be on a SSD, as it shows the biggest improvement there. Pictures or videos which take up a lot of space should be stored on a normal magnetic hard disk, as those are cheap. So I need to make space for a second hard disk. Luckily, Sony uses a standardized IDE slim DVD drive, which can be swapped for a universal SATA to IDE hard disk cage. By exchanging her 80GB hard disk with the 320GB of her external drive and inserting a 96GB Kingston V+ 100 SSD, she will have ~400GB of space, which is more than enough. Next, I swapped her RAM with the RAM from my broken Toshiba notebook, increasing it to 4GB. With this combination, her notebook should outperform most current notebooks. As the Toshiba had a WiFi N card, I swapped it into her notebook, too.</p>
<p><a href="http://www.qianqin.de/wp-content/uploads/2011/10/hookup.jpg"><img class="alignnone size-thumbnail wp-image-727" title="Internal USB hook up" src="http://www.qianqin.de/wp-content/uploads/2011/10/hookup-150x150.jpg" alt="" width="150" height="150" /></a>The next two problems can be solved &#8220;relatively&#8221; easy with an internal USB hub. At least I thought so until I tried soldering it inside. Every single guide on the web showed how you removed a USB slot permanently to connect the hub, which is simply not possible in my case as that would make the mod visible. So I needed to find a different way. I found a user connecting his USB hub to a mini PCIe port, as it should contain USB data lines. Unluckily, the free mini PCIe slot on the Vaio didn&#8217;t have working USB signal lines, so I needed a completely new approach. Then I spotted the Expresscard slot, which is nothing else than an external mini PCIe slot. I checked the PINs and it did have working USB signal lines there, but&#8230; my girlfriend uses a SD-card reader in that slot which of course already uses those lines. The only solution now is to hijacking the signal line, connecting the card reader to the internal USB hub and the hub to the lines. Luckily, I found that both USB signal lines were connected in series with capacitors, giving me a clean pleace to intercept them. I installed a 4 port USB hub, connected her mouse and keyboard dongle in 1 of each port, a 3G HSPA stick in a third and connected the last port back to the Expresscard slot. Now the only thing left is to place everything so I can still close the notebook perfectly. Done.</p>
<p>So how fast is her notebook now? Well, it boots twice as fast as a brand new i5-2 notebook with a clean Windows installation. Every applications starts up way faster. Unless you decompress a file or do something really CPU intensive, the Vaio will feel faster than any €500 notebook. In fact, if you take 3G HSPA into consideration, a comparable notebook would cost €800. So how much did the upgrade cost?</p>
<ul>
<li>Kingston 96GB V+ 100 SSD (€100)</li>
<li>320GB hard disk (€35)</li>
<li>3G HSPA stick (€20)</li>
<li>WiFi N mini PCIe card (€20)</li>
<li>Universal HDD cage for slim-drive (€15)</li>
<li>2 GB RAM (€15)</li>
<li>4 port USB hub (€5)</li>
</ul>
<p>That&#8217;s €115 in my case or € 210 if you don&#8217;t have any parts, which is a lot cheaper than a €800 notebook isn&#8217;t it?</p>

			<content:encoded><![CDATA[<p><img src="http://www.qianqin.de/wp-content/uploads/2011/09/cover-530x298.jpg" alt="" title="Samsung Galaxy S High WAF Wireless Inductive Charging Mod" width="530" height="298" class="alignnone size-large wp-image-710" />You guys wanted to see it, here it is. The complete progress of making an inductive charging mod with no visible wires, no visible soldering points, free usb port and easily removable back cover (or simply high <a href="http://en.wikipedia.org/wiki/Wife_acceptance_factor">WAF</a>) squeezed into one Youtube video. I only had one try and couldn&#8217;t plan much ahead, but as you will see on the video, the whole process is fairly simple and straightforward. This mod will void your warranty, though I don&#8217;t think a Samsung repair man will be able to find traces of this mod on first sight if removed cleanly.<br />
<span id="more-709"></span><br />
Parts you will need for this mod:</p>
<ul>
<li>Palm Pre back cover and Touchstone dock (thanks to <a href="http://www.ebay.de/itm/Palm-Pre-black-Touchstone-Bundle-Sonderpaket-Sparset-/370534305323">handingo for providing the parts</a>)</li>
<li>Self-adhesive copper foil</li>
<li>thin wire</li>
<li>small (#00) Phillips screwdriver</li>
<li>soldering iron</li>
<li>solder</li>
</ul>
<p>And here is how you do everything:</p>

			<content:encoded><![CDATA[<p><a href="http://www.qianqin.de/wp-content/uploads/2011/09/galaxysinductive.jpg"><img class="alignnone size-large wp-image-690" title="Samsung Galaxy S Plus on wireless inductive charging docking station" src="http://www.qianqin.de/wp-content/uploads/2011/09/galaxysinductive-530x298.jpg" alt="" width="530" height="298" /></a>Well, after my Motorola Milestone 2 was sent in for repairs for 3 times in a row now and I decided to not use any Motorola devices anymore, so when Mediamarkt offered the Samsung Galaxy S Plus for €269, it was an instant buy. I mean, how can Motorola send me a defective unit back from repair not only once, but twice? I haven&#8217;t received it back yet from their third try, but oh well, let&#8217;s hope somebody on eBay will be happy with it. Okay, no more Motorola, all Samsung now, the Galaxy S Plus works way better anyway. In fact, everything is perfect, except for one little thing. The USB connector of the Galaxy S Plus is on the top. How do you dock a phone in portrait mode with the USB connector on top? eBay suggested a rather ugly method with plugging a cable on top. So I remembered the Palm&#8217;s inductive charging feature and wanted it on my new phone. But all guides on the internet are either <a title="ugly induction hack" href="http://lifehacker.com/5598744/hack-an-induction-charger-to-work-with-any-cellphone">ugly</a> or <a href="http://www.instructables.com/id/Samsung-Epic-4g-Inductive-Charger/">voided the warranty</a>, but I wanted the best of both worlds, so my mod has to be invisible on first view and don&#8217;t void the warranty of my all new phone. (As the Galaxy S is build identically as the Galaxy S Plus, this mod should work flawlessly with the Galaxy S, too.)</p>
<p><span id="more-689"></span>So how did I do it? Well, the basics are the same, take a Palm Pre back cover (€10) + Touchstone dock (€20) and tear off the inductive circuit from the Pre back cover and insert it into the cover from the Samsung Galaxy S Plus. The tricky stuff is modifying to the micro USB plug. To be exact, to cut it really short so it doesn&#8217;t stand out. This requires some skill and a lot of patience. As the plug is really small, you definitely don&#8217;t want two wires coming from it. Two wires would require really small solder points which offer no stability at all and will just break after some days of use. So what you will have to do is to only wire the +5V only. Luckily, you can get 0V from everywhere inside, I used the micro SD card slot for it. The rest is pretty straight forward. Take a look at the video to see the finished mod:</p>
<p><iframe width="540" height="331" src="http://www.youtube.com/embed/740JaJ-UX0A?rel=0&amp;hd=1" frameborder="0" allowfullscreen></iframe></p>
<p><a href="http://www.qianqin.de/wp-content/uploads/2011/09/microusb.jpg"><img src="http://www.qianqin.de/wp-content/uploads/2011/09/microusb-150x150.jpg" alt="" title="Sawed off micro USB plug" width="150" height="150" class="alignright size-thumbnail wp-image-700" /></a>If you like to rebuild the mod, here are some more hints for you:</p>
<ul>
<li>Remove all pins from plug by pulling them out forcefully before sawing.</li>
<li>Buy more micro USB plugs to play with, as you will certainly break some before you finish one. I suggest using the inner (black) part of one plug combined with the metal casing of a different plug.</li>
<li>Bent one pin as shown on the picture so it can fit into 2 pin slots, then cut it to a length that it won&#8217;t shorten any pin.</li>
<li>Make the solder point as long as possible, this will add more stability.</li>
<li>If you happen to have black hot-glue, use it as a finish to cover up the complete slot.</li>
</ul>
<h4>UPDATE</h4>
<p>After I have shown this mod to my girlfriend, she wants it too on her Galaxy S. But she wants to keep her micro USB port free for cable connections for USB charging. Warranty is not much a problem for her, so she just wants a really pretty looking and invisible mod. If you like see a guide for that, drop me a comment here and I will document the process for you guys.</p>
<h4>UPDATE 2</h4>
<p>So as so many of you seem to want it, I&#8217;ll be filming the whole process of creating the high <a href="http://en.wikipedia.org/wiki/Wife_acceptance_factor">WAF</a> mod. For this, I will try to do this mod with no visible wires (why do girls hate them?), everything else as invisible as possible, backcover easily removable just as without the mod. I already ordered the parts and I am waiting for them to arrive. The camera is ready to roll.</p>
<h4>UPDATE 3</h4>
<p>Still waiting for parts to finish the high WAF mod, half of the mod is already completed and documented. I ordered them on Monday and they still haven&#8217;t arrived. Until then you can take a look at a <a href="http://blog.qinyujie.net/2011/09/24/557/">step to step guide for this version of the mod</a> done by <a href="http://www.qinyujie.net/">Yujie</a>.</p>
<h4>UPDATE 4</h4>
<p>Done! <a href="http://www.qianqin.de/2011/09/28/high-waf-inductive-charging-mod/">View the results here</a>.</p>

			<content:encoded><![CDATA[<p><a href="http://www.qianqin.de/2011/08/23/goodbye-and-hello-webos/hptouchpad/" rel="attachment wp-att-637"><img class="alignnone size-medium wp-image-637" title="HP TouchPad" src="http://www.qianqin.de/wp-content/uploads/2011/08/hptouchpad-259x300.jpg" alt="" width="259" height="300" /></a>The fire sale of the discontinued HP TouchPad has reached Germany. For € 99, a TouchPad could be yours, if you could manage to reach the online shop of HP. It was obviously down, as everyone wanted to get hold of this bargain. So I walked right into the next Mediamarkt and tried talking the salesman into selling me one for the discounted price. Of course he hasn&#8217;t heard anything about the sale, and I was unable to show him the new price because the HP online shop was down. So I had to make him let me talk to his superior and he then agreed to let me reserve one until they get the new price. So when I was walking out of the shop to get some food, I suddenly got a call, well, guess who called, the salesman who didn&#8217;t want me to sell the TouchPad. The price drop is here, time for me to pick my first and probably last WebOS device.<br />
<span id="more-635"></span><br />
So right now, I am writing from my new tablet. And I have to say, I am very surprised by WebOS. It feels like the first tablet that can actually multitask the way I want, or more the way I was used to in Windows. It is so easy to switch between apps. Not only that, the native Skype support blew me away. It was something that was missing on the iPad for years, but WebOS already comes with it and works so flawlessly.</p>
<p>My plan was to buy the TouchPad and put Android on it, but now, after trying WebOS, I want to keep it, as it really seems to be a nice OS for tablets. I have tried the iPad for quite a while but I could never find iOS very useful. It takes forever to switch between email, instant messaging and the browser. Android at least let me see all incoming events, but with webOS, the true multitasking fun is back. It&#8217;s actually fun to switch between the apps.</p>
<p>Maybe it was HP&#8217;s goal to let people try WebOS this way. I would have never bought a WebOS device if the price wouldn&#8217;t be this low. Now they should have quite some market share. People who bought the device will start making apps for it. This might be just the kick WebOS needed to start off. I wouldn&#8217;t pay more money for it, as tablets are pure couch browsers to me, but for this purpose, I find WebOS actually being the best choice for a tablet OS. I wonder if I will see any new WebOS devices around in the future.</p>

			<content:encoded><![CDATA[<p>My friends know that I like to make fun of Apple fanboys, but now I&#8217;ve bought a Apple product myself. I was struggling really hard at &#8220;Media Markt&#8221;, oscillating between the cash desk and the shelves, but I did it! I bought an iPad from Apple. The iPad has everything, big screen, long battery life, (too) easy to use interface, chinese hand-writing input, WiFi and simple games unlimited&#8230; It has everything my Mom needs! That and the unbeatable price of € 499 for an actually solid looking tablet, I have to admit there is no better and cheaper solution for my Mom to surf the internet and playing easy games without having to worry about viruses or where the next power outlet is.<br />
<span id="more-593"></span><br />
So if I&#8217;m already giving my Mom an iPad as a present, I wanted it to look even greater, so I decided to individualize it with an engraving. Apple doesn&#8217;t offer engraving for iPads yet, so I looked for companies who would offer such services and found a <a href="http://www.berlingravur.de/">company doing laser engraving called printjob24</a>, only 5 minutes away from Gravis at &#8220;Ernst-Reuter-Platz&#8221;. I called them, made sure they could engrave pictures and not only names and went there with the iPad. I choose a really old photo of my parents and me, converted it to a black and white picture and filmed the whole procedure. The result looks really great:</p>
<p><a href="http://www.qianqin.de/wp-content/uploads/2010/08/ipad.jpg"><img class="alignnone size-large wp-image-594" title="iPad" src="http://www.qianqin.de/wp-content/uploads/2010/08/ipad-530x392.jpg" alt="" width="530" height="392" /></a></p>
<p>The people at printjob24 are really nice, so I can really recommend them if anyone else needs an engraving. Here is the video:</p>
<p><object classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" width="425" height="344" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,40,0"><param name="allowFullScreen" value="true" /><param name="allowscriptaccess" value="always" /><param name="src" value="http://www.youtube.com/v/rj1eFxhzfPw&amp;hl=de&amp;fs=1" /><param name="allowfullscreen" value="true" /><embed type="application/x-shockwave-flash" width="425" height="344" src="http://www.youtube.com/v/rj1eFxhzfPw&amp;hl=de&amp;fs=1" allowscriptaccess="always" allowfullscreen="true"></embed></object></p>

			<content:encoded><![CDATA[<p>Now after the HTC Desire is finally available in Germany, my cousin immediately ordered one, which finally arrived last saturday. I couldn&#8217;t resist testing the 1 GHz Snapdragon compared to the Motorola Milestone I own. But I never got to doing that&#8230;</p>
<p>When I looked at the HTC Desire&#8217;s screen, I found it to be looking really odd. I could see red pixels between black and white transitions, which is really irritating when reading text. When looking at a pure gray image, it looked like I was looking at a white background through a mesh. It gave me the feeling of looking at a cheap $100 low-res phone where pixels still could be seen.<br />
<span id="more-580"></span><br />
After having used high-res screen devices like the HTC Touch Diamond or the Motorola Droid, I&#8217;m pretty sure that something was wrong with the screen of the HTC Desire, it simply didn&#8217;t look like a 800&#215;480 screen to me. Well, I dropped the seller an email, saying that the phone my cousin got is broken. But today, I got my hands on a Google Nexus One, which I immediately examined for this weird behavior. The Nexus One got the exact same problem. Is that coincidence? I started asking other people whether they are seeing the red pixels, too, but most of them replied no.</p>
<p>I started to dig deeper and found an interesting article on <a href="http://arstechnica.com/gadgets/news/2010/03/secrets-of-the-nexus-ones-screen-science-color-and-hacks.ars/">arstechnica.com</a> describing this problem. Basically, the Desire/Nexus One screen only has 2 colors /pixel instead of 3. So the screen is a mesh of red/green and blue/green pixels instead of every pixel having red, green and blue. The whole thing is based on quite a lot of rules of human eye reception, like</p>
<ol>
<li>Green is a color the human eye is most sensitive to, the screen has the full amount of green pixels.</li>
<li>As the human eye is more sensitive to contrast than color, having a high display density should make this effect invisible.</li>
<li>Having the color information only on every 2 pixels is a very commonly used procedure in compressing video to save space without visible quality loss.</li>
</ol>
<p>But there is one problem with not beeing able to show all 3 colors at the same time. To show one white pixel, you would need to turn on 2 pixels, as red, green and blue has to be on to mix a white. This wouldn&#8217;t be a problem it the colors weren&#8217;t alternating between red and blue. So instead of having a nice black with almost invisible blue side, you get a eye-catching ugly red/blue border on every white to black transition.</p>
<p>Well, I sure hope that is the only device HTC will build with such an ugly screen, if not, I&#8217;d recommend people to switch to that nice Retina Display of the iPhone 4.</p>

			<content:encoded><![CDATA[<p><img src="http://www.qianqin.de/wp-content/uploads/2010/05/office52.jpg" alt="" title="office52" width="150" height="192" class="alignnone size-full wp-image-571" />If someone would offer you Office Ultimate 2010 for only €52, there is only one explanation for the price: bootleg! No need for discussion, unless&#8230; it&#8217;s Microsoft&#8217;s own offer for you! You heard it right, Office Ultimate 2010 for €52. I mean, 93% savings, isn&#8217;t that something we only know from those illegal pirated software spam mails?</p>
<p>But this time, it&#8217;s a legitimate offer from Microsoft. It&#8217;s called &#8220;<a href="http://www.microsoft.com/student/discounts/daswahreoffice/default.aspx">das wahre Office</a>&#8221; here in Germany and offers Office 2010 for the unbeatable price of €52 to students. You can only buy Office Ultimate 2007 right now, but as soon as 2010 is released, you will get a <a href="http://office2010.microsoft.com/de-de/msproducts/tech-guarantee/?CTT=97">free upgrade</a>. I&#8217;m a big fan of Outlook with Exchange, so well I guess the €52 are well spent here. Don&#8217;t hesitate, the offer is limited to the end of june 2010!</p>
<p>Not only Microsoft is offering these increadible cheap packages, if you use Adobe Software for example, they offer 80% savings for their CS5 packages on their <a href="http://events.adobe.co.uk/go/gntray_store_edu_de">education store</a>. Adobe even allows commercial usage of their software, so if you happen to design websites with Photoshop or create videos with Premiere Pro, the production premium set is available for around €350 on <a href="http://geizhals.at/deutschland/a523658.html">several online shop</a>.</p>

			<content:encoded><![CDATA[<p>Well, making your blog really fast is quite a nice thing for your visitors. And lately it&#8217;ll even fall under SEO, as Google now takes Page Speed into account for ranking your website. So how do you get your freshly installed wordpress site really fast? It&#8217;s actually really easy.<br />
<span id="more-559"></span><br />
First, you will need a PHP accelerator, which caches precompiled PHP Opcode, so it&#8217;ll run much faster. PHP is a script language, so it takes really long to parse and interpret you PHP code, a Opcode cache would simply skip this time. You will need a dedicated or at least virtual server with root access to do this. I&#8217;ll show you how to install APC, as it is really easy to install and use on Debian Lenny. So to install APC, simply run the following command as root:</p>
<pre>aptitude install php-apc</pre>
<p>Afterwars, edit the /etc/php5/conf.d/apc.ini and replace it with the following:</p>
<pre>extension=apc.so
[apc]
apc.enabled = 1
apc.shm_size = 64
apc.ttl = 7200
apc.user_ttl = 7200
apc.mmap_file_mask = /tmp/apc.XXXXXX</pre>
<p>Now restart Apache with <code>/etc/init.d/apache2 restart</code> and APC is up and running.</p>
<p>Next you will need to setup mod_expires to configure client side caches. mod_expires is usually already installed when you use apache2, so you will only need to enable it via <code>a2enmod expires</code>. After that, find the default vhost configuration file (usually /etc/apache2/conf.d/default-config) and add the following lines:</p>
<pre>ExpiresActive On
ExpiresDefault "access plus 300 seconds"
ExpiresByType text/html "access plus 1 day"
ExpiresByType text/css "access plus 1 day"
ExpiresByType text/javascript "access plus 1 day"
ExpiresByType image/gif "access plus 1 month"
ExpiresByType image/jpg "access plus 1 month"
ExpiresByType image/png "access plus 1 month"
ExpiresByType application/x-shockwave-flash "access plus 1 day"</pre>
<p>Now restart Apache again with <code>/etc/init.d/apache2 restart</code> and client side caching is ready to go.</p>
<p>The next step is installing a WordPress caching plugin with APC support, like <a href="http://wordpress.org/extend/plugins/w3-total-cache/">W3 Total Cache</a> and setting up Page, Minify and Database Caching with Opcode APC, which is so easy I don&#8217;t even need to explain it any further. </p>
<p>There is one optional step, which helps improve page loading time on site with a lot of static content (like images). As connections are limited per hostname, having a lot of images will cause the site to load really slow, as the browser has to wait until the current images have finished loading before it can load new ones. To solve this problem, simply create multiple ServerAlias in your virtual-host file and serve your static content from them. It is strongly recommended that you use a hostname wrapper in this case, which generates the same Alias for each file. You certainly don&#8217;t want a user to start loading the same file from different hostnames, as that would actually slow down the page speed. There are several ways to solve this problem. I created a function that calculates a number from the filename and use that as a subdomain where the file is being loaded from.</p>
<p>With this steps, page loading time dropped from 10-20s to 1-2s on my web projects (Full page load with images and scripts). It feels really nice to see the page load up so fast.</p>
