Checking MD5 Hash on a Mac

When you download a file from a website, they usually come with a 128 bit hash the called MD5 hash. The 32 digit hash is used to check for the integrity of the file to make sure the file hasn’t been altered in any way. So, how do you check MD5 hash on the Mac OS? Open up your Terminal and type the following:

md5 linux.iso

The MD5 command will spit out a 12b bit hash that you can compare it with on a website’s download page. If the hash match, then the file’s integrity is intact. If it doesn’t match, then the file has been altered and compromised. Get rid of it. You never know what’s in it.

iPad Mini Due In March 2013

So soon. For those of you holding off to purchase the first generation of the iPad mini, you may not have to wait too long. Rumor on the street says that a second generation of the iPad mini with Retina display is due in March of this year. That’s one quick turnaround.

A friend of mine who is a bit older, said that he couldn’t really tell a difference between an iPad mini without a Retina display, and the original iPad equipped with a Retina display. I think he is saying the screen on the iPad mini is not as bad. I think the screen size of the iPad mini and the screen resolution somewhat makes it quite acceptable.

But, the upcoming Retina display on the iPad mini will really make the screen much clearer. Most people would be able to tell a difference. Some apps will really take advantage of the Retina display and make the iPad mini shine. So, I can’t wait for this second generation of the iPad mini to get here. And March is just around the corner.

iPad Magic

Here’s some iPad magic by Simon Pierro, courtesy of Mashable. Here is Simon’s Youtube channel if you’re interested in seeing all his magic tricks. He is a decent magician, and he has put on a ton of work with the iPad. It’s refreshing to see a magician use and embrace technology, and incorporate it with something as old as magic.

iMac Mini or Mac 21.5

I bought a Mac Mini a month ago. I love it. The only gripe I have is I wished I had a better monitor. But, that’s not the Mac mini’s fault. Lately, I have been thinking about swapping my Mac Mini with the new, cool, sleek, 21 inch iMac. How is that possible? There’s a holiday promotional right now from October 27 until January 7. Any computers bought within this window can be returned or exchanged. Typically, it’s only a two week return policy.

So, I’m debating whether to swap units. The Mac mini that I bought actually has a faster processor than the low end iMac. The Mac mini has a 2.3GHz quad-core Intel Core i7 processor, while the iMac runs on the 2.7Ghz Intel Core i5 processor. As far as upgrades, the Mac Mini is a lot easier to mod. You can add easily more memory, a second hard drive or SSD to the unit without much of a hassle. The iMac is not so easy. Obviously, the best feature of the 2012 iMac is the screen and the skinny form factor. The only downside with my Mac mini setup is, I need a better monitor.

iPad Mini With Retina Display

It’s a good thing I didn’t get one of those most-sought-after iPad minis this fall. You guessed it. Apple already has plans to upgrade the iPad mini with a retina display sometime next fall. It’s a good thing I wasn’t in such a hurry. I think the Retina display is worth the wait. I wonder if the news/rumors today will dampen everyone’s enthusiasm to purchase them this year, or will people still buy them because they just couldn’t wait. I would wait. That’s what I would do. The only other question left is, will the iPad mini remain at $329.

Google Play Growing In Asia

I recently got a new Droid Razr on Black Friday. I ordered it online. I have been playing around with it particularly with Google Play. Computerworld has an article about how Google Play is outpacing the Apple App Store in Asia, particularly in Japan and South Korea. Here are some highlights I gathered from that article.

The growth of Google Play in Asian countries has been so robust that Japan exceeded the U.S. for the first time in Google Play revenues in October.

Google Play revenues grew 311% from January to October, while App Store revenues grew 13%.

The success in Asia for Google Play is partly because more people use smartphones and tablets in Japan and South Korea than other countries.

Since the App Store is expected to earn nearly $5 billion in 2012, that means Google Play is on pace to earn about $1.25 billion in 2012.

Remmina Remote Desktop Client

Remmina is a free and open-source project released under  GNU GPL license. Remmina is a remote desktop client written in GTK+. It’s perfect for system administrators and travelers needing to work on remote computers. Remmina supports multiple network protocols like RDP, VNC, NX, XDMCP and SSH.

I currently use Remmina to view my Macbook Air remotely from my Linux desktop. It works great so far. I have it running for a better part of the day. It’s seem to be responsive. The remote mouse and keyboard works perfectly. The screen quality is not quite near as the Macbook Air display, but then again, it’s a remote desktop client.

Remmina is available to Ubuntu and Linux Mint users. You can install by typing on the Terminal:

sudo apt-get install remmina

The Remmina Remote Desktop Client icon is available under Menu > Internet.

Mac Mini With USB 3.0

Along with the iPad mini being introduced on October 23rd, Apple also plans to upgrade the Mac Mini with USB 3.0 ports. Will there be processor and storage upgrades for the Mac Mini? There is no telling at the moment. I guess, we just have to wait until the October 23 announcement. Regardless, the USB 3.0 upgrade is good news for prospective Mac Mini buyers, like me.

iPad Mini At $249

You gotta love leaks. The word on the street (internet) according to Gizmodo is, the new iPad mini is going to be priced starting at around $249 for the 8GB version. Higher models will be priced more. Here’s an excerpt from the LA Times:

The posted picture, which according to the blog comes from an anonymous informant, shows 8 GB versions of the iPad mini will go for 249 euros, or about $320. But Gizmodo is reporting that the U.S. price is likely to be $249. As it points out, Apple charges roughly the same figure in Europe for the third generation iPad as it does in America. It doesn’t conpensate for the foreign exchange difference.

As for the inventory list provided by the German blogger, the price goes up to 349 euros for the 16 GB model, 449 euros for the 32 GB device and 549 euros for a 64 GB version. The cellular-connected versions of the iPad mini start at 349 euros for the 8 GB model, 449 euros for the 16 GB model, 549 for the 32 GB and 649 for the 64 GB versions of the device.

Now, how accurate these figures are, you really can’t be sure. But, it looks very promising for people looking for a smaller and affordable iPad. Interestingly enough, Amazon’s Kindle Fire is priced at $249. So, it looks like Apple is matching the price of the Kindle Fire.

Capture Screenshots on Mac OS X

Capturing screenshots on the Mac OS is quite easy. You’ll just have to learn the commands. So, without further ado, here are the keyboard shortcuts to get you going.

Press Spacebar to select the entire active screen. Click the mouse or the touchpad to capture the screen. If you want to just capture a small section of the active Window, hold and drag the mouse or touchpad, when you see the crosshair with the screen axis numbers when prompted. The screenshot will be automatically added to the desktop.

How to capture an entire screen

Command + Shift + 3

To capture the entire desktop screen, use the keyboard by holding the Command and Shift keys, and pressing the number 3. The screenshot will be automatically added to the desktop.
