MacHeist 3 Apps

I decided to buy the MacHeist 3 bundle this year, and here's a list of the apps I got, with their respective ratings (out of 5):

  1. Scribbles *****
  2. iStock ***
  3. MiniOne Racing ***
  4. BabelBloX *****
  5. Typinator ***
  6. DEVONthink ****
  7. Hyperspaces **
  8. Overflow *****
  9. Fresh ****
  10. Webbla *
  11. iSale ** (registering this one is a pain)
  12. Picturesque *****
  13. SousChef *****
  14. World of Goo ***
  15. PhoneView (I don't have an iPhone)
  16. LittleSnapper ***
  17. Acorn *****
  18. Kinemac ****
  19. WireTap Studio *****
  20. BoinxTV *****
  21. The Hit List **** (still waiting for license)
  22. Espresso ***** (still waiting for license)
  23. Cro-Mag Rally ***
  24. Times ***** (awesome user interface, kudos to the developer)
  25. EventBox ***
  26. Big Bang Board Games *****
For only $39, this was a really good deal - all of the apps bought separately would have cost me well over $1000, and I like the "Buy 12, Take 26" plan!

Snow Leopard Will Be Seen at WWDC

Apple's Mac WWDC page gives it away that Snow Leopard and its technologies will take stage at WWDC. Quoting directly from the page,
Provide state-of-the-art media playback, capture, and manipulation of rich media with QuickTime X.
It is important to note that QuickTime X is a Snow Leopard (10.6)-only technology.

Firefox on iPhone is a Bad Idea

I was on Digg this morning when I came across this article (here's the Digg link). Matt Asay, author of CNET's "The Open Road" does have some pretty good points on why Firefox should be on the iPhone, and I completely agree with him on how throwing Firefox onto an N810 isn't really going to bring about wondrous numbers of community supporters, but it is simply not a good idea to let Firefox become an iPhone application.

To set the scene, everyone knows about the iPhone. Everyone's super-excited about the App Stores - users and developers alike - and all its possibilities. Apple's competitors have taken a lot of ideas from the iPhone, and mobile operating systems are all the hype these days (that includes netbooks). As far as I'm aware, the N810 runs Android, for which applications are written in Java.

When I first saw the title of Matt's article ("Why no iPhone support for Firefox mobile beta?"), I thought, Why is this question even being asked? First off, it's obviously going to be a competitor for Mobile Safari (which Apple won't even allow in the app store ), and Firefox's not that fast of a browser, either, in my opinion, compared to Safari. Besides, all iPhone applications are written in Cocoa. Let's see Mozilla trying to rewrite all of Firefox, its plug-in architecture, its support for themes, etc, all in Cocoa Touch. Furthormore, quoting directly from the article, one of the many other reasons that Firefox won't be available for the iPhone any time in the near future is because "it [has] to do with restrictions on run non-SDK code[.]"

Not only that, but it would also provide two completely different SDKs for software developers to chose from: the iPhone SDK and whatever Firefox plug-in developers use. This is really dangerous for Apple. Apple wants in no way for there to be an alternative development SDK if not that of the iPhone - that's why Flash isn't on iPhone, and won't be, either. If a developer prefers Mozilla's way of doing things and wants to target iPhone owners as potential users, there would be a visible drop in terms of iPhone SDK developers and, hence, Mac users (and possibly the number of new Mac developers too).

All in all, Firefox on the iPhone is a really bad idea. Although, idealistically, it sounds nice, Firefox won't be able to live up to its "I'm a fast and customizable browser" promise.

Spotlight and the Finder

There are two things that bother me about Spotlight in the Finder (I've already submitted these to Apple as feedback):
  1. If I'm in my Documents folder and I start typing in the Spotlight toolbar item, I'll want Spotlight to start searching within my Documents folder, not throughout my whole Mac. If I want to do that, I'll either go into the root directory or search from the menu bar.
  2. Also, when dragging multiple files in a spotlight results window, it is not clear that all the files are being dragged. It looks like only one file is being dragged.

Microsoft's Silverlight Gaffe

I'm not sure whether this could be classified as false advertising or what, but I don't think Microsoft can count megabytes... Perhaps it's that large for Windows, but I'm pretty sure Microsoft's able to update information based on the detected operating system.

Snow Leopard Obviously will be Darker

Honestly, how many times must I say it? Snow Leopard will be darker. After a lot of research, it seems I was the one of the first ones (if not the first one) to suggest that Snow Leopard's interface will be darker:

and now, QuickTime X (image from AppleInsider):

The image may be an artist's rendition, but it's based on reported facts, and what should stand out the most is the black title bar. Besides that, there's also the new iMovie and GarageBand 09 interface elements other people have pointed out.

More Feedback to Apple

Simply put: the Go menu should display what's in the Finder's sidebar, be it along with what's already in the menu or not.
You too can send Apple feedback at Apple's Feedback page.

Picked up my Cocoa Book

Last night (29 February 2009) I went over to a local bookstore to pick up my long-awaited copy of "Cocoa Programming for Mac OS X" (3rd edition). The cover is really nice with multiple textures, but I was surprised at how the 3rd edition is just about as thick as the second edition. I ventured into the table of contents for comparison, and I found out that the following chapters were removed:
  • Using NSTextView
  • AppleScript
  • Creating Frameworks
  • GNUstep
  • Creating Interface Builder Palettes
I understand why the palettes and GNUstep chapters were removed (Interface Builder no longer uses Palettes and GNUstep is somewhat dormant at the moment). In return, a few other chapters were added, most notably on web services, Core Data, and Core Animation.

Of course, it's not just chapters added that counts - a lot of new things have been written, new challenges have been added, and it really seems like a much better book.

Merging mkdir and cd

I oftentimes use mkdir and cd together, as in mkdir project && cd project or mkdir project; cd project and I believe many people probably do the same thing. I always found it tedious and repetitive to have to type in the directory's name twice, so I thought, "why not merge these two into one command?" Something like mkcd project could do both jobs at once and reduce typing; it's like hitting two birds with one stone, so to speak.

The biggest problem I've encountered in the implementation of a seemingly simple idea is that when programs or shell scripts are run they are child processes. That said, you can't have a simple BASH script that reads "mkdir $1 && cd $1" because it would only switch to the directory while running as a child process instead of actually switching to the directory. The same applies to the system( ); function in stdlib.h (in C, C++ - cstdlib -, and related languages).

I am considering submitting the idea to the GNU project. The idea has been sent and I'm awaiting their reply.

I Switched to KDE 4

After KDE 4.2 was released, I have to say, I was hooked. The interface got cleaned up, everything is more elegant, practically bug-free, and not as sluggish as the original release (it's not as fast as GNOME yet, but it's been alright). As a big GNOME fan for quite a while now, the 4.2 release is almost at what could be considered commercially-ready. Will it be KDE that will tumble the world onto the GNU/Linux platform? I even remember seeing a photo of a bunch of KDE 4-based computers on display in Germany to celebrate the 4.0 beta. I can't seem to recall where I'd seen it, though.

Below is a screenshot of my current desktop, and I love it:

How Linux Shuts Down

Have you ever wondered how a computer can turn itself off without any manual controls? It's quite simple, actually. Here's how it works in Linux:

First off, all running processes are terminated. This means first closing files (and, in certain cases, saving them) to ensure that the system's stability is maintained and then completely forcing all processes to stop.

Afterwards, all external (non-root*) filesystems (including swap partitions) are unmounted.

If anything goes wrong in any of these steps, the filesystem may become unstable and may even render the installation useless. This is a warning to not interrupt your computer while it is being shut down! I personally know someone who happened to do so; his root filesystem became corrupted and a reinstallation had to be done.

For the actual hardware shutdown, a signal is sent to the power supply (similarly to how a signal can be sent to open a disc drive), which triggers the final shutdown.

(thanks to Tobor for help on the hardware info)

* root here means the root directory, not the root user.

Making Firefox Fit Into KDE 4.2

If you've ever run a default install of Firefox in KDE 4.2, you most likely saw tabs that looked terrible (at least on Kubuntu Intrepid). At first I thought there was a problem with my GTK theme settings for KDE, but then I figured out the problem was simply the theme. I installed KDE4+Firefox and now everything looks just fine.

Networking Ubuntu and OS X with Samba

Let's assume you have both Macs and Ubuntu PCs in your network. How can you set them up so you're able to access Ubuntu from a Mac and vice-versa? It's pretty simple via Samba.

Setting up Ubuntu
  1. Right-click the folder you want to share and select Sharing Options.
  2. Unless you already have Samba installed, you may be asked to install it now.
  3. Set all the options you want - select the name of the share (this will appear in the Finder's sidebar), if you want to allow other people to be able to write in the folder or not, and if you want guests to be able to access this folder.
  4. After saving the modifications, a link to the Ubuntu computer should appear automatically in the Finder, with the iconic BSOD icon
Setting up Mac OS X
  1. Open System Preferences > Sharing. Select the file sharing checkbox.
  2. Select the "Options..." button.
  3. In the pop-up menu, add the names of the users whose Public folders will be shared and select "Share Files using SMB."
  4. In Ubuntu, select Places > Connect to Server... and select Windows Share.
  5. Type in your computer's network address (usually smb://***.***. ... where the asterisks represent your IP address). You can access your computer either from the Places menu, the desktop, or in network:/// in Nautilus (or your file manager of choice).

Windows 7 Editions

I'd say Microsoft made its best post-Vista move recently. Windows 7 will come in the same options as Vista (except Business is now Professional again), except only Home Business and Professional will be publicly available for retail.

Starter Editions will now be available internationally and Home Basic will be around only in selected countries (shouldn't it be the other way around?).

Overall, I think this was a nice move on Microsoft's part.

Microsoft Previews Future Windows UI

Microsoft seems to be previewing the future of the Windows UI with Office 14. Take a look at SharePoint's window border. It may be that, with Microsoft flattening the Windows interface in Windows 7 (as can be easily seen in the new Explorers - the file manager and Internet Explorer), Office is to follow suit. Besides a flatter and brighter ribbon, the Aero interface is to be flatter as well. 

Either that or the user who leaked the screenshot applied a special theme...

Quasi for PDF Grouping

A while ago, I downloaded Advanced Linux Programming (it's available for a legal free download) in its PDF form. Each chapter was separate, and, due to alphabetical order, the appendices were earlier in the list than the actual chapters. This created a huge delay from when I opened the folder to getting to the actual file I wanted to read. Then I decided that there should be something to fix this.

Quasi is a very easy-to-use, step-by-step application. It starts by asking you which files you want to group together. You can select multiple files at once and later reorder them. When you go to combine the files, you're shown the final file to see if you like it or not. If you do, all you have to do is save it (and, optionally, apply a Quartz filter). If not, the file is automatically deleted off your hard drive.

Quasi is available for US$9.99 .

Understanding Cocoa Notifications

Thanks to Martin Pilkington and Steven Degutis for helping out with this article!

Being a Cocoa developer, you are probably aware of delegates. Delegates are "helper objects" that run custom code when called by its object. For example, the class NSWindow has the delegate method windowDidMove:. If I have a Controller object with that method implemented and I set it to be a certain NSWindow's delegate via [myWindow setDelegate:aController]; then whenever the window moves, my delegate object will be notified of it and run the code in the windowDidMove: method's implementation.

The problem with delegates, however, is that an object can only have one delegate object, so it can't notify multiple objects of something at once via delegation. Also, you can't get feedback from all instances of a class, while with notifications, you can call a method when any window in your app is moved, minimized, closed, etc. That is the great part of a notification: notifications allow the notifier to notify multiple objects at once.

The two main classes used in notifications are NSNotification and NSNotificationCenter. NSNotification is very simple: it contains a name for the notification, the object that sent the notification, and an optional userInfo dictionary. But where the real magic lies is in NSNotificationCenter. With it you can basically do three things: add an observer, remove an observer, and post a notification. 

Code Dissection: Adding an Observer
Let's continue using the window moving idea. Take a look at the following piece of code:

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(aWindowMoved:) name:NSWindowDidMoveNotification object:nil];

  • [NSNotificationCenter defaultCenter] is a shared instance.
  • addObserver:self sets the current class to be the observer of defaultCenter. This is useful in a controller class, but self can be replaced to any other object that contains the method referred to in the next argument.
  • selector:@selector(aWindowMoved:)  is the name of the method within the observer that should be called when the notification (in the next argument) is sent out. Selector declarations should have something similar to (NSNotification *)aNotification as an argument, so aWindowMoved: is defined as -(void)aWindowMoved:(NSNotification *)aNotification; in the observer's @implementation.
  • name:NSWindowDidMoveNotification is the name of the notification. You can find these in the documentation for objects that have support for notifications
  • object:nil says that any object that has an NSWindowDidMoveNotification notification can notify the observer. If you wanted to make this more delegate-like, though, you could specify an object, such as object:myWindow
Code Dissection: Removing an Observer
Removing observers is just as simple. The simplest way to remove an observer is like so:

[[NSNotificationCenter defaultCenter] removeObserver:self];

That should be pretty much self-explanatory. However, if you want to remove one observance and keep the rest intact, use the -removeObserver:name:object: method. Here are a few examples:

  • [[NSNotificationCenter defaultCenter[ removeObserver:self name:NSWindowDidMoveNotification object:nil]; removes self as the observer for all move notifications.
  • [[NSNotificationCenter defaultCenter] removeObserver:self name:NSWindowDidMoveNotification object:myWindow]; removes self as the observer from move notifications from myWindow specifically.
  • [[NSNotificationCenter defaultCenter] removeObserver:self name:nil object:myWindow]; removes self as the observer from all notifications from myWindow
Other possibilities exist as well.

Try it out!
Write an application with a window and a panel. The window should have a check box saying "warn me when this window moves." When the window moves, have the panel appear with a message on it: "a window moved" if the check box is checked. 

Hint 1: Check Boxes are a type of NSButton. 
Hint 2: NSButtons need neither delegates nor notifications. Being derived from NSControl, they only use targets and actions.

Is Research the Best Part of Microsoft?

Here's something I was genuinely thinking lately: is Microsoft Research the best thing Microsoft has to offer today? Seriously, think about it. Forget Windows 7; forget Office 14; forget Live Search; forget the Zune. Here are a few things, oriented to both developers and consumers, that are currently being offered from Microsoft Research:

  • Songsmith - Ok, I must admit that the ad is really cheesy, but it seems like a feature that Apple should have put in GarageBand. It's easier to sing into a microphone and have the program make up the song for you rather than pulling out instruments and messing around with them."Songsmith comes up with a music that matches your voice," touts the ad, which seems very interesting. Even better would be a mixture of the two. (By the way, is it just me or is that a MacBook Pro they used, using a flower sticker to cover up the Apple logo?)  
  • Kodu - I'd bet a lot of younger children would like to write their own games on their computer. With Kodu, anyone (but it's being marketed for children) can visually develop a game without typing out any code. I'm not sure if you need some Kodu interpreter to run the games or if they can run as stand-alone application on PCs and Xboxe 360s, but it seems very enticing.
  • WorldWide Telescope - It seems that WWT (as Microsoft abbreviates it) is a sort of Google Earth for the rest of the universe. 
  • Boogie and Spec# - Boogie is an "intermediate program verification language" and Spec# is something similar, except it developed separately into a separate programming language. Neither of the websites make it very clear as to what each of the products is.
  • Coconut - a .NET library for working with matrix mathematics
  • Domestic 2.0 - this is more of a philosophical project that tries to design new user experiences based on their socio-domestic background. 
Sadly, many of the projects have incomplete descriptions, such as HDR Image Hallucination, Chalice, and  CAPTCHA 2.0 .

Besides these main projects, there are numerous other small projects being developed.  I think it's time for Micrsofot to drop Office with OpenOffice and Symphony (which is based on OpenOffice) as completely viable office suite alternatives and focus more on these interesting products that very few people know about.

Windows 7 Beta Review

So, I went onto MSDN, downloaded my copy of Windows 7 Beta (build 7000), and here are a few notes of what I think of the new version of Windows, specifically my overall impression of it, the new Aero and system-wide features, the interface redesigns, and the overall usability of the new operating system.
Setup is surprisingly beautiful for Microsoft's previous standards, especially the boot screen, which says "Starting Windows" and after a while little balls come flying out and turn into a flashing Windows logo, and the "Setup is checking your computer" part. 

I originally thought the taskbar would look too big, but it looks really nice and the look was well thought-out. When you hover over an inactive application's icon, a little blue light appears under it, with two lines on the side. I decided to launch IE. On hovering, a white light follows the mouse cursor and the background adapts to the app. It's nice to be able to close an app via thumbnails. It really reminds me of the dock in Mac OS X, or (as some Microsoft reps like to call it), a copy of the Windows 1 and Windows 2 desktop. Right...

As far as moving taskbar icons is concerned, GNOME has already had that for a while now.

The notification bar seems too empty. The icons are too small. Perhaps 2 rows like in KDE? on hover, a blue triangle appears under the icons.

Aero Peek isn't very obvious. You have to hover over the "Show Desktop" button. It can also be enabled when you hover over a thumbnail so you can see where the window is on the desktop.

Aero Snaps was already available in previous versions of Windows, but fairly hidden and called "Arrange windows horizontally/vertically" and "Cascade windows" instead of "Snaps."

Windows is still obviously document-focused instead of app-focused like OS X. If you have two windows of Word open and one of Paint, and you use "Aero Shake" (when you shake a window to minimize all the other ones), all other windows go down and all you have is a lone window. Very useful, though

Jump lists are nice. Not much to say about them, though, except there isn't an exact standard to what their content should be.

Control Panel has been revamped; the view is simpler, and finally, Wallpaper Slideshows are available (like in KDE and Mac OS X). Interestingly enough, wallpapers are now called backgrounds. Yet another feature copied from GNOME.

The new redesigned Paint is really interesting. The tools are clearer and there are new shapes. Unlike the Office apps, which have a big round button with the app icon that is the "File" menu, the file menu is a separate drop-down menu in the ribbon. There are now 4 different brush styles. Upon being created, a new shape is treated like an object, so it can be moved around and manipulated without messing with the rest of the image. What would be nice is to be able to go back and separately select that shape again. Now, it's more obvious that you can personalize the color palette. The bottom of the window has become more useful, easing magnification and with quicker access to selection size and overall window size.

There is still no spell checking in Wordpad.

Gadgets are now seen as separate Windows, which may go in front of others, closed, etc. I'm glad there's no sidebar anymore, and the new free gadgets remind me of KDE 4.

XPS viewer isn't IE and is obviously written in WPF.

Now, let's take a look at what the new Explorers have to offer:

  • Interface is too flat
  • there's a special toolbar just for web slices and bookmarks. a bookmark bar is what I've been waiting for for a long time.
  • on first open, you have an option to turn on Suggested Sites, a web slice that recommends sites based on your browsing history.
  • Nicely enough, the default search provider is Google (finally!)

Explorer (file browser)
  • brighter look
  • cleaner than the Vista explorer
  • you can now resize the space between the address bar and the search bar
Libraries are a bit strange. It seems like a plan to replace file folders, which still exist. It's a nice concept, but very strangely implemented. The Start Menu shortcuts link directly to the libraries. Even when clicking the user's name link, you get a list of your libraries. The only user folders MS expects to be accessed with frequency now are Desktop and Downloads. In fact, after going back to the user folder, what had been renamed in Vista do "Documents," "Pictures," "Videos," and "Music" have now been suffixed with "My" ("My Documents," "My Pictures," etc), like the older versions of Windows. However, Microsoft thinks users will rarely access their "user folder" anymore (even save dialogs offer you to save your files in libraries instead of actual directory folders).

I find it a nice touch that, unless you're hovering over the drop-down lists on the sidebar, the little arrows for the lists are hidden.
So,  there are a lot of new features, new looks, new designs, and Windows 7 is really stable (although it boots up rather slowly). It's still the same old Windows, though. It still has the same basic functionality since the one established in 1995, but the revamp is a nice one.

Today's Old Computer: Imlac PDS-1

It's been quite a while since the last time I wrote a "Today's Old Computer" article (click on the old computer portal at the top to see some of the other ones), so as I was paying the Old Computers Museum website a due visit, I came across a mostly-undocumented interesting machine called the Imlac PDS-1. This "professional" computer was released in 1970 and programmed in assembly language.

Upon further research, it's quite surprising what this "minicomputer" could do! Its graphics were completely vector-based (something modern operating systems only beginning to implement. As a further matter, I can't believe it's already 2009, 39 years ahead of 1970, and we're still dealing with raster graphics on our displays) and could do multi-window editing of text, graphics, photosetting. Even more surprising to some would be the fact that the Xerox Alto, which was designed in 1972 and constructed in 1973, was preceded by the Imlac PDS-1.

The Imlac had a sort of precursor to the mouse as we know it today. Instead of moving around a little round object and pressing a button, one would point at the screen with a light pen and press a pedal (funny that this should be mentioned - I came up with this idea last year or the year before but it seems to be 39 years old or even older).

Oh, and what's up with the portrait displays?

Either way, the Imlac PDS-1 seems like a computer such ahead of its time that it's quite surprising! Vector graphics throughout its assembly-based operating system (ok, that latter part maybe doesn't so amazing, but I still haven't seen a person or group bragging in this millenium that they wrote a completely vector-based operating system in assembly language), a precursor to the GUI, photosetting, and rather small compared to the sizes of computers in that time! RAM and other hardware specs don't even matter that much when it comes to talking about the Imlac. I'd like to see something like this today!

Alpine and Mailing Lists

Alpine is a rather well-known email client. It stands for "Alternatively-Licensed Pine." The developers at the University of Washington (Seattle) wanted to maintain a free code base while keeping a close relationship to the trademarked Pine.

I like Alpine. It's really nice, but I only use it for my text-only mailing lists. That's because a lot of modern newsletters and personal email are filled with images. Sure, I know I could just download the images from within Alpine and open them with Feh, but then I'd need to try to piece together the images to see what part of the email the image belongs to... all in all, it would be some tedious work.

However, with text-only emails, Alpine has the speed and stability I need to quickly get to a message, read it, reply (if needed), or send out a new one in a way that is yet unmatched by GUI mail clients. Moreover, the clean interface makes using it all the more fun.

Why not try out Alpine? Most distros' package managers should have it, and it's easy to set it up for using your Gmail account and IMAP.

New Features in GTK+ 2.15.0

Thanks to TuxMachines for helping this post give me over 1,424 total views today!

Two days ago (1 January, 2009) the development release leading up to GTK+ 2.16.0 was released. Here are the new features that will be available in the next release as far as widgets go (I've especially been waiting for GtkFileChooser to be able to show file sizes):
* GtkFileChooser
- Optionally shows file sizes
- Mounts volumes when necessary
- Picks better mime icons

* GtkEntry
- Can show icons at either side of the entry, which can be made
clickable, drag sources, etc
- Can show progress information
- Picks the best available placeholder character for invisible entries
unless it is explicitly set. See the invisible-char-set property
- Input methods work again in invisible entries
- Invisible entries can optionally display a caps-lock warning. This
can be turned off with the caps-lock-warning property

* GtkStatusIcon
- Uses an extension of the tray icon spec to negotiate RGBA support.
This is also supported by the GNOME panel. For details, see
- Supports scroll events, middle clicks and rich tooltips

* GtkLinkButton
- Respects user-defined tooltips
- Has a default url hook

* GtkBuilder
- Can construct menus
- Can associate accel groups with windows
- Child properties can now be translatable, e.g.

* GtkOrientable
- A new interface implemented by all widgets that have horizontal and
vertical variants

* Printing support
- Print-to-file can save to non-local files
- Page rendering can be deferred to a thread to avoid blocking the

- GdkKeymap emits a state-changed signal when the Caps Lock state

There are also new theming and translation features, as well as four newly-deprecated functions. See the mailing list announcement for more details.

Even the Small Talk will be Big

Maybe the rumors are true, and the iPhone nano is coming along. MacRumors has a shot of a banner somewhere in San Francisco. Small Talk... iPhone nano is small... Big news...?

Except it's IDG-sponsored and it's very similar to a MacWorld slogan. Who knows? Maybe they decided to match it up this year.

A Better Desktop Button for Ubuntu

In the bottom left of Ubuntu's bottom bar, there is a Show Desktop button. I never use it, though. If I need to show the desktop I usually just switch to another virtual workspace, so I replaced it with something more useful: a Window Selector menu.

With this Window Selector, all open application windows (including those on other workspaces) appear in this little menu, allowing me to quickly switch to another app without having to search every single workspace for it. Besides, it looks rather nice, as well :)
