D Link DWR 131 Hands on And Tata Photon + Config

These days I started travelling a lot and I use a Tata Photon+ data card to connect to Internet. Unfortunately I couldn’t get a Working driver of Tata Photon+ for Mac Lion OS X and I ended up purchasing a D Link DWR 131 Router. It’s a 3G router, which convert your 3G connection into Wi-fi connection and give you the power of portability. This works with almost all the popular Indian 3G card along with Data card like Tata Photon +, MTS, Reliance and many more. I will come to the setup part later but first lets look into some of the features of D Link DWR 131 Router.

D Link DWR 131 Router feature and review:

I’m a big fan of Belkin and D link product when it comes to router and I picked D link 131 router for almost 360o INR ( $70) from a local gadget shop. Though, you can always search it online and get it for much cheaper price and deal.

DWR 131 3G router comes with 1700 mAH battery and offer many feature which you may or may not use. Specially, if you are looking for a cheap and simple solution, there are other cheap options too but if you are looking for something long term and offer more features like Ethernet connection, multiple Wi-fi connectivity and simple to configure Wizard, D link DWR 131 router could be one of the good pick. This 3G router supports multiple network (EV-DO/CDMA/HSPA+/HSUPA/HSDPA/UMTS) and in the accessories it comes with one Charger, Battery, Router and a Lan wire.

Configuring D link 3G router with Tata Photon +:

The reason I ended up buying this router is because of two reason:

  • No Tata Photon + working driver for Mac Lion OS X 10.8.2+
  • Connecting multiple device with same data dongle.

I could have used my Mac book as Wi-fi router but that is not very convenient when you are travelling and you want to preserve battery as much as you could.  By default this router doesn’t work with Tata photon+ but you can manually set it (Which is easy and configure your D link router to work with Tata Photon +. Follow this step by step guide:

  • Switch on your D link DWR 131 Router and put in battery and connect it with Charger.
  • Plug in your Tata Photon + data card
  • Open 192.168.0.1 in your browser
  • Default username: admin Password: Blank
  • Click on Setup > Manual Internet connection Setup

Now in the Ethernet Port select Wan and use Dial up profile as manual.  There are few settings which you need to make and those are easy. 

  • Country : India
  • Telecom : Others
  • 3G network: WCDMA/HSPA
  • username: internet
  • password: password
  • Dial number: #777

Click on Save settings and it will reboot the router and you will be connected to internet using your Tata photon + data card. Check out this screenshot for any confusion:

D-Link DWR-131 tata Photon plus config

That’s it and now you can enjoy the power of Wi-fi even when you are moving and you can connect to multiple devices at one time. If you are a frequent traveller and have multiple gadgets with you, you should consider buying D link Pocket router or from any other company, not only it will give you piece of mind, but you will also be connected to Internet all the time.

Do let me know if you are stuck anywhere and I will try to find a solution.

Can’t be opened because it is from an unidentified Developer: Solved

I recently purchased Mac book air and got a free upgrade to OS X mountain lion which added some new security feature, which will prevent installing of 3rd party apps. I was trying to install VLC and MAMP app and everytime I got this error on my Mac: “App Can’t be opened because it is from an unidentified developer.” If you are running OS X mountain Lion 10.8+, you might be getting the same error. Here is a screenshot of this error:

unidentified developer app installation Error

Follow the below mentioned guide to solve this issue.

Fixing Mac Unidentified Developer App Installation issue:

If you are installing app via official App store, you will not be facing any such issue and even if you are download app from few sites, you will not be facing any issue. But for most of other mac apps, this warning message is basically a security measure and you can quickly fix it by making some changes in security settings of your mac.

Go to System preferance and click on Security and privacy. Under general tab, below you will see a golden lock icon, click on it to make changes. Once you disable lock, you will be able to make changes in all greyed option.

Simply select the option under ” Allow applications downloaded from” and select the option which says “Anywhere”, it will give you another prompt and select the option “allow from anywhere”. Enable the lock again and now you will be able to install any 3rd party applications on your Mac. Below is a screenshot to understand the process:

allow 3rd party Installtion Mac Mountain

Though it’s a good feature but Apple should work on increasing the number of apps on Mac app store. As right now there are very few apps and I’m sure many of you might not live without 3rd party mac apps.

I hope this quick fix will help you installing any kind of apps on your Mac and if you still have trouble installing 3rd party apps, do let me know and I will find an answer.

Fix: Hash Sum Mismatch Cydia Error While Installing Installous 5

Hash Sum MismatchEarlier we talked about Installous 5, which has one of the major feature now (Download files via torrent), but many users faced issues while installing Installous 5. Earlier, an update was not showing in my jailbroken iPhone 4 and later when Installous 5 update was visible, on Installing I was getting this error : Hash sum mismatch error. Here are some of the workaround to fix this issue.

2 Ways to fix Hash sum Mismatch error in Cydia:

If you getting this error for the first time, I suggest you to retry or try downloading any other app in Cydia and see if it works. Else, here are some of the possible solutions which you can try.

Reboot:

This is the basic step and this worked fine for me. I closed all the apps, restarted my iPhone and tried updating to Installous5 and it worked for me. Even in forums, many users reported the same and it’s working for them without any issue.

Use Alternate source:

Usually we use http://cydia.hackulo.us to install Installous, but you can also try alternate cydia sources like SinfuliPhonerepo. here is the repo address: http://sinfuliphonerepo.com

simply go to Cydia > Sources > Edit > Add and add the following source and then search Installous 5 under it, and install. I tried this method in iPad 2, and it worked for me.

Reinstall Installous:

Another method is to delete installous and remove it’s source and re-add it. This is one method, which I have not tried but many users reported it worked for them.

I tried the first 2 fix for fixing Hash sum error in Cydia and it worked for me. Last but not the least, if nothing works for you: You can start from scratch by re-jailbreaking your phone and installing Installous on fresh device.  Though, I suggest to use this only, when nothing works for you.

Here are few more fixes, which are suggested by users in forum:

Reset Network settings:

You can try resetting your network settings in iPhone or iPad and it may work. Also, reboot your modem once.

Reload Cydia:

On the cydia homepage, reload it to update it and then try and see is you still getting “hash sum mismatch error“.

I tried the torrent feature and for now, there are very few apps with magnet link available, but in coming days we can expect way more. Anyways, do let me know which solution worked for you and if any of these worked (It should), don’t forget to share this post on Facebook and Google plus.

Download & Install Installous 5

Installous 5Installous which is one of the best app for jailbroken iPhone (iOS devices), got an update and now Installous 5 is ready to download and you can install on your iOS device.  If you have not upgraded to latest version of Installous yet, you will be seeing a message like this when you will open Installous:

” We have released an update for Installous in Cydia. It includes BitTorrent downloading support and a few other improvements. Please update”.

There are many noticable changes in Installous 5 and here are some of them:

Torrent support:

Installous 5 not supports .magnet links. Not, it supports torrent downloading, and probably one of the few apps which works smoothly with torrent downloading on iPhone. I will post a step by step tutorial later. It will also seed the torrent at the time of downloading and it will work in wi-fi only. Also, you can pause and resume the torrent downloading, which will be very handy for users.

Supports iOS5 notification:

This is one feature which I believe every iOS5 users will love to have. Now, Installous5 supports iOS 5 notification using custom BulletinBoard plugin.

If you have not installed Installous on your jailbroken iOS devices yet, here are guide which will help you to get started:

How to upgrade to Installous 5:

I assume you have already Installous Installed on your device and you are simply upgrading to latest Installous 5. Open Cydia > Click on changes and it will show Installous 5 as an upgrade option, simpley upgrade it and enjoy new features in Installous.

There are some known issues when you try to upgrade like:

Facebook Camera App : Bulk Upload & Add Image Effects

Facebook bulk Image UploaderSome time back when Facebook acquired Instagram, we expected something awesome from Facebook. Today, Facebook launched a new app in App store which is a camera app for iPhone Facebook users.

Facebook launched Facebook camera app for iOS. As name suggests, this is an image uploader app for Facebook but not only that, it has much more option then simple image uploading. Probably, this is the reason why Facebook acquired Instagram for $1 billion.

Let’s look into some of the features of this new app from Facebook.

Facebook Camera app : Review

This new Facebook app integrated the features of Instagram app and made image uploading on iPhone/iPad and other iOS device so easily. If you are one of those who wants to upload bulk images from your camera gallery on Facebook, or take and upload picture to Facebook, this free Facebook Cam app is for you.

You can also browse images uploaded by your friends and you can like and comment on it. With this launch, here are list of Instagram filters, this official Facebook cam app has got:

Contrast, Cool, Light, Emerald, Bright, Golden Copper, Rouge, Cream, Coffee, highlight, Boost, Neon, B+W

Though, I’m hoping to see more awesome Instagram filters in coming days. In recent time, Twitpic launched their Twitter image sharing app, and it has also some awesome image effects. Anyhow, getting back to this app, if you are one of those who love to upload images on Facebook, this dedicated app will make your work easy. Specially, earlier uploading multiple images on Facebook was a headache and this new app, you can quickly select all/multi images from your image gallery and upload them.

When I installed this app, it didn’t even asked for my login (I believe because of official Facebook iOS app I’m using), and here is a screenshot of an Image which I’m taking from my iPhone and adding effects using Facebook camera app.

Facebook Camera App iOS

Once you have added the effect, all you need to do is click on compose or put the tick mark and click on upload to share photos on Facebook. You can crop photo, if you like which is another great feature for photo editing. You can also tag people directly using this Fb camera app.

You can download this app from official app store here. Facebook has launched another app call Facebook app manager few days back, which will let page admins manage their pages easily.

I’m not sure why Facebook is coming up with separate app for everything and why not integrate all the features in official app. Specially, this image effect features from Instagram, will be very handy for Facebook app for iOS. Lets see, what all new features we get to see in this Instagram Facebook Camera app, but for now do try and let us know your review on the same.

The Evolution of Gaming PCs [MicroGraphic]

No one pushes a harmless CPU and graphics card to the very brink quite like a serious gamer. It’s a point of pride with many players that their gaming system can skillfully walk the line between bleeding-edge game play and suddenly melting processors. (It’s one thing to have an advanced cooling system, but it’s something else completely when you feel compelled to keep a fire extinguisher close at hand.)

Gamers can go to extreme lengths just to squeak out a better refresh rate or a few more frames per second, and they’re quick to take advantage of the latest technology as it is released. Over the last 30 years there have been some significant advances in CPU and graphics technology and an occasional plateau as well. Together the gaming industry and gamers have pushed the evolution of the common CPU and associated graphics cards to the point that it’s hard to believe how far we’ve really come.

Evolution of Gaming PC's

The Genesis of Gaming PCs

The Commodore 64 was introduced in January 1982 with a CPU that clocked in at 1.024 megahertz and featured a wholesome 64 kilobytes of RAM. The 16 colors on the 320×200 display definitely don’t seem like much today, but it was enough to play the likes of Q*Bert, Pole Position, and Dig Dug. The games were simplistic but fun, and 30 years later we still talk about them and play them on a variety of systems. These specs seem miniscule by today’s standards, but they were enough to make the Commodore 64 the best-selling single personal computer model of all time.

For the next decade, things really didn’t get that much faster. Intel began to release the X86 series throughout the 80s and early 90s, which made some strides and created an environment where games like SimCity and Doom could start changing the way we thought about games. We now had enough power in these computers to start creating an immersive experience. These games would set the tone for the industry for the next twenty years.

Major CPU Advances

The Pentium Pro started to really increase the performance of the average gaming computer, and we saw these CPUs start to clock much higher speeds. Between ‘95 and ‘99 we saw a consistent growth in processor speeds, but it was in 2000, with the launch of the Pentium 4 and AMDK7 that we started to see some major advances in capabilities.

In the gaming world games like Doom led to Quake, Unreal, and Half-Life, and real time strategy games began to take off. We had the power to manage millions of polygons for a complete first-person experience and well-balanced and addictive games like StarCraft began to make competitive (and professional) gaming possible.

Jumps and Plateaus in Gaming Pc’s

Between 2000 and 2004 there was a major jump in technology, and the Pentium 4 nearly doubled its speed from 1.5 GHz to 3.06 GHz (on average). This happened in time for the push toward online gaming and MMORPGs like World of Warcraft as well as some new developments in the FPS world. Serious gamers could really push the graphics and frame rates of their PCs to get an edge on their competition, and huge guilds of virtual adventurers could raid a massive dungeon without experiencing undue amounts of lag.

Once we hit this point, though, the actual clocked speeds of these processors hit a plateau for a while. This wasn’t because there weren’t any advances in technology, it’s just that the CPUs had changed their focus to dual and quad core processing. Of course, this didn’t stop serious gamers from overclocking their new Core i7 and pushing it to a nice, warm 4.2 GHz to really enhance their Modern Warfare 3 experience.

An open question to gamer out here, which graphics card and processor do you prefer for your gaming Pcs?

Air Playit : Stream Multi-Media Content from Computer to iOS Device

Air Playit is going to change the way you transfer video and music from your computer to iPhone/ iPad, just say goodbye to the days when you have to sync the media from iTunes. As long as long as your iPhone or iPad is connected with WiFi, 3G/4G network, just play your desired videos and music on your iOS device directly, irrespective of the file format.

Here I would like to introduce this innovative video and audio streaming software to you. Air Playit is composed of a server and a client application, and the connection between them is the wireless network (WiFi, 3G or 4G). The server is mainly for sharing the videos and music folder, and the client application is used mainly for staying connected with the server to get the media streaming from it.

Air Playit

Setting up Air Playit server onto the desktop is simple and quick. Run it and click “Shared Folder”, you can not only add video/music folder from hard disk but also import the iTunes playlist for streaming. Other functions could also be found here, for instance, click “Permission” tab and users can set permission level (Admin, Kid and Public) to the shared file. Under the “Information” tab, the IP address of your server computer is shown. The “Web” tab allows users to access the shared media using any web browser with the URL shown on the server.With Air Playit installed, you can transfer your videos and music wirelessly with little time and effort.

Key features of Air Playit:

Live conversion

Built in 320 different video/audio codecs, Air Playit offers real-time conversion for the HD and SD videos when streaming, so that you can play any video and music on your device instantly.

The supported video formats include the HD videos MKV, M2TS, AVCHD, TP, MPEG-TS, AVC and MOD etc and regular videos such as MPEG1/2, WMV, ASF, AVI, MOV, RM/RMBV, FLV, MP4, H.264, M4V, WTV, WebM.

Air downloader

Air Playit also works as remote video converter software for you to add/manage video conversion tasks on your iOS device, which enables you to download the audio video files to your device wirelessly over WiFi, 3G/4G network and play them offline at any time.

HTTP server

Air Playit enables users to access the videos and audios stored on a PC or Mac using any web browser.

Besides the above features, Air Playit has even more to offer. For instance, it enables users to add remote server by specifying IP address and supports multi-audio tracks video for you to choose any language in the video file. It can also remotely power off your computer after finishing watching. Compared with other video/audio streaming software, Air Playit has an innovative feature- TV out that empowers you to stream video & music to TV via iPhone iPad etc. It is a good idea to use Air Playit and start a new way to transfer your videos and music and play them on your beloved iOS device.

How to use Air Playit to transfer media from computer to your iOS device.

Download Air Playit server (both Mac and Windows versions are available) and install it onto the computer, and then install the client app for iPad or client app for iPhone on your iOS device.

Run Air Playit server, click “Shared folders” and add the video or music folder that you need to stream to your iPad or iPhone.

Air-playit-Server

 

On your iPad or iPhone, run the client app and add your server and tap it. The client app will detect and connect to the server automatically by Bonjour service. If sometimes it can’t find the Bonjour connection information, you need to manually input the server address which is shown on the server or close the firewall for a try. Here I would like to take iPhone for example.

Browse the shard folders under the server, then tap your desired folder, select any file that you need and click “Play”, just play the music and video on the go without waiting for the conversion.


Using this software will certainly take care of pain of transferring multi-media files from your desktop to your iOS device. Do let us know your review of Air playit or any other streaming software if you are using?

UltraSurf : Free Desktop Proxy Software

UltraSurf Desktop Proxy softwareWebsite blocking is nothing new to internet world. Usually education institutes, organization, companies blocks social networking websites like Facebook, Chatroulette and many others to enhance productivity. Though, I’m strongly against internet censorship and therefore here I’m going to talk about one of the best desktop proxy software call Ultrasurf. There are many other similar software’s like Ultrasurf such as: Your-freedom, JAp and many more but I always prefer Ultra surf over anything else.

What is Ultrasurf:

As I mentioned above, Ultrasurf is a desktop proxy software which connects to proxy server and you need to tweak your browser proxy settings to connect to Ultrasurf servers. Once you are connected to their server, you can start accessing any blocked website in your organization. The interesting part about Ultrasurf is, you can carry it in your pen drive and it doesn’t require any kind of Installation. So if software installation is blocked at your work place, you need not need to worry.  If your organization doesn’t allow changing your IE proxy settings, you might need to find another alternative, which we will talk in other post. I hope this give you a brief idea about what is Ultrasurf and now, lets look into setup part of this useful free desktop proxy software.

Note: It’s a Windows based application

How to use Ultrasurf?

Using Ultra surf is easy and all you need to do is download Ultrasurf from their official site. If proxy sites are blocked in your organization, you might need to download Ultra surf at your home and carry it to your office. You can use Dropbox or Google drive to quickly gain access to Ultrasurf in your office.

Once you have gained access to a copy of Ultrasurf, simply double click on u.exe and run it. It by defaults set your Internet explorer and Chrome proxy settings to use Ultra surf servers.

If you are using any alternate browsers like Firefox, Opera: You need to add following proxy settings

  • 127.0.0.1: 9666

Once done, you will be able to access all the blocked sites in your office. This also helps in removing ISP based blocking. For example, recently in my country most of sites like Vimeo, PirateBay has been blocked and we have been getting message saying “Access to this site has been blocked as per Court Orders”, using Ultra surf you can get rid of such warning and access all sites including Piratebay and other torrent sites. Though I have not tried configuring uTorrent to use Ultra surf, but if you have done it, do let us know via comment.

You can also use this proxy software to hide your I.P and access websites with different I.P. If you have been in habit of using Proxy websites in your college and office, shift to Ultra surf and see the difference.
