Get File MD5, SHA1 Checksum on Mac OS

On Windows, I was used to installing a separate program for everything: one to view images, one to browse PDFs, and another to calculate a file’s MD5 or SHA1. On Mac OS X, you don’t have to go through all that trouble! If you want to calculate the MD5 or SHA1 checksum of a file, there is a built-in tool for it. ...

[Sold] Used Lenovo G570 Laptop, About Two Years Old, Everything Works Fine

I recently bought a new laptop, so I want to sell this G570. I originally bought it for a skills competition, because the laptop the school provided didn’t perform well, so I got one for myself. I use it mainly for programming, and not very often, so it has no hardware problems. The exterior has no scratches or damage either. Here’s the information about this laptop: ...

MacBook Air 2013 Unboxing: Claimed to Have the World's Longest 12-Hour Battery Life

Since I was about to start university, and Apple had just released the new-generation MacBook Air, I couldn’t resist and splurged on one. The biggest highlight of this year’s MacBook Air is its 12-hour battery life. When I saw that line at the launch event, I thought they were joking. But later reviews from overseas confirmed it’s real, and that’s what made me really want to buy it. With such long battery life, I don’t need to bring the power adapter when I go out, and I don’t have to worry about running out of power halfway through. For someone like me who goes out often, that’s very convenient. Besides the long battery life, it has many other updates, such as 802.11ac wireless networking, a super-fast SSD, and the new-generation Intel Haswell processor, among others. ...

Amazon Kindle Touch Unboxing & Who Should Buy a Kindle?

Right after New Year’s, I bought a Kindle Touch from Amazon in the US. I had read lots of articles online, both praise and criticism. The most common complaints are these three: it has a black-and-white screen, it has too few features, and the e-paper responds too slowly. These three were also my biggest worries XD. But once the device actually arrived in Taiwan, I realized my worries were unnecessary! ...

TinyUmbrella Helps You Back Up the SHSH of Your iPad and iPhone for Downgrading

Sometimes when you want to downgrade your iPad or iPhone (hereafter iOS Device), you find that the downgrade keeps failing. This is because newer iOS devices have a built-in protection mechanism that blocks you from downgrading the device. This design exists to prevent users from jailbreaking. When a new iOS version comes out, some people accidentally tap update… Usually the latest iOS version cannot be jailbroken, so users who have updated can only downgrade in order to jailbreak. This is when a big problem appears: you cannot downgrade…… The TinyUmbrella introduced today is software that can help you downgrade successfully. It can back up something called SHSH for you. Once you have backed up the SHSH, you can downgrade successfully~ ...

Unboxing a Bluetooth Keyboard and an iPad Stand~

Actually, this post was supposed to go up on 7/4. That day I went with some netizen friends to visit the multimedia expo at the World Trade Center in Taipei, and I saw a few things and…. ended up buying them without really planning to. I felt a little heartbroken, but I didn’t feel I’d lost out, since the things are really practical and I didn’t overpay. So what did I buy? The answer: a Bluetooth keyboard and a stand for the iPad. ...

iOS 5 Preview: iMessage, the New Notification Center, Free PC, and Over a Hundred Changes!

If I remember correctly, around 1 AM this Sunday (6/7), Apple held WWDC and announced three of the most important things: Mac OS X Lion, iOS 5, and iCloud. I happened to be free that day, so I stayed up to read AppleLife’s live text coverage (Apple prohibits live video broadcasts). My impression after reading it: iOS 5 has improved so much that it might even stop you from wanting to jailbreak. iCloud is also very good, because it can save you a lot of time when updating iOS by pulling your music, photos, and other data straight down from the internet. ...

Some Tricks You Probably Didn't Know That Make Using Your Computer Faster!

Actually, I first learned these tricks while studying vi, a plain-text editor under Linux. Later, when I tried them in other text editors (basically anywhere you can type text~), I found they worked the same way. These little tricks can speed up how quickly you process documents a lot. Also, I’ve recently been preparing for the TQC Chinese-English typing test, and practicing these tricks has helped my typing to some extent. ...

ASUS RT-N13U Wireless Router Unboxing – Besides Wi-Fi, It Also Works as an FTP Server!

I had some spare money lying around, and I’d put up with my old D-Link wireless router for a long time. It kept dropping the connection, and especially whenever my iPad opened the App Store, it would disconnect immediately = = So with both the motive and the budget in place, I decided to buy a new wireless router~ At first I thought about going to Guanghua (Taipei’s electronics market), but then I figured it’s easy to get ripped off there, and Guanghua generally doesn’t accept returns. If the router I bought didn’t meet my needs, I’d be furious. So I went browsing on PChome instead xD ...

Two Days Late: iPad 1 Unboxing, 16GB WiFi Model

As the title says, this unboxing post is two days late. I bought this iPad on Thursday night (3/10), but then I got so busy that I didn’t have time to write the unboxing post… Actually, I’ve wanted one since the iPad first came out, and I kept saving money until now, when there was a special offer~ So I went for it. Some people asked why I didn’t buy the iPad 2, since it’s cheaper and faster, right? I think the news media may have spread the wrong idea. As soon as the iPad 2 was announced, Apple cut the price of the iPad to a minimum of NT$12,900, while the iPad 2 was expected to cost around NT$16,000. Yes, the iPad 2 does perform better, but my own experience with the iPad 1 is that its performance is already good, and you rarely run into lag or crashes. If only you could turn off iOS multitasking… ...
