Orbitron is freestyling on the second half of the video.

Listen to 4:23

“… great to see release - my man goes
Dmitry is in the circle — he spins and let goes
with the palm on a hand over jacket
grant stand I can grand slam when I got here
Tip the beat, rock and nod, spot the block, till I get off to my forehead
Ya’ll know where its at, ya’ll spin on a hat …”

My ankle is feeling much better! I can finally start dancing again!!!

Just uploaded some footage to youtube

and this:

Any kind of excitement and anticipation make it feel like time is sloooowing down. Think about it. Lets say you’re so excited to do something with your friends on Friday. You have these huge plans. The whole week is going to feel like a month, because you just can’t wait for it to be that day!

I think as people get older, they get less and less excited about Life in general, with an attitude “been there, done that”. Nothing surprises them. Nothing really takes their breath away, or disappoints them. They’ve been through many ups and downs etc. Its all about the same…

Don’t do that! Get excited :)

I think the key to enjoying life is always to be “in the mystery” like its your first day on this planet, to be excited to see what’s around the corner. I think its somewhere right in between of whats called “The beginner’s mind” in Zen, and “becoming a child again” in Matthew 18:1 .

Hope, desire, and passion make Life worth living!

Is there something you always wanted to do but gave up on? Get really inspired and time will fell normal again, just like when you were a little kid.

Stock Wing

So, here is a picture of my car (first pic). I think the stock wing is kinda big and silly, but it is functional … if I am taking 90-degree corners at 160 mph.

This car isn’t meant to be “pretty” — its all purely functional. But I think taking a wing off might make it look more subtle.

Without the Wing

More “grown-up” look :) Less flashy and less attention from cops. Real subtle and clean. The only problem is when you take the wing off, it leaves 4 small holes in the trunk.

No Wing, but with a little carbon fiber lip

I am leaning towards this look, it completes the car lines and also covers up those holes in the trunk that keep the wing on. (BTW, its made by Rexpeed and its called “Type-C” lip).

OK, please take a second and vote or leave a comment below if you like:

Campusing is a climbing exercise or “move” depending on your style :-) where you climb up the wall without using your feet. You don’t have to be able to do this in order to climb — There are plenty of climbers who can climb very hard but can’t even come close to doing what you’re about to see in these videos.

Climbing is not all about power and strength, but it is sure nice to have endless supplies of it!

Todd Meyers’ Campusing Workout: We recorded these videos at Wild Walls (Climbing Gym in Spokane) a few years ago. I just found these videos, so I am sharing them.

Warmup Set: Doing one-arms on a campus board, while skipping every other rung

Set 2: Doing one arms on very small (Metolius) rungs, skipping ever other one!

Set 3: One-arm pullups with with 10 pound ankle weights on each leg. Skipping every other rung!

Set 4: More one-arms with ankle weights!

Set 5: Last but not least…

1. Empty your concerns so you have room to think clearly!

I am starting to think GTD stole all of my ideas :) Anyway, you can’t be productive if your mind is cluttered with to-do lists, pressing events, unsolved problems and projects. There is a really simple solution for this – just write it down, get it out of your head and realize that you’ll come back to it later, on your own terms so for now it won’t bother you. I’ve always thought the mind is similar to computer RAM – it has a limited “operational capacity”. Even though you can increase it, your “effective memory” is the thought space not preoccupied by background processes, or loops such as unresolved concerns and to-do lists. These things interrupt you from focusing. They make you constantly context-switch. A Zen-like approach is much more effective.

Maintain an All-Day “Journal” Event:
I carry a PDA and a paper notepad (in case the former fails). On my PDA (iPhone) I create an all-day (calendar) event called “journal”. Inside it, I make notes of anything important that happened during a day. I like to track it in software, because later I can search it for keywords. I’ve been meticulously journaling my life this way for the past 6 years and it has worked well for me.

Write down your concerns in a Daily Recurring Event
It is very convenient to have a daily recurring event (I renamed mine to “bucket”, credits to GTD). As you go through your day, open this “Bucket” event, and write down any kind of concerns, ideas, to-dos, etc in the notes section. I also carry a voice recorder (so if I am driving I can record things I need to remember and put them into my calendar later (plus its not a bad idea to become aware of what you sound like to people)).

If you do these 2 things you’ll have the ability to (1) search through your Life journal, and (2) copy and paste your items from bucket to other software. Make sure to make monthly backups of your calendar by burning them to a CD.

2. Process your daily “bucket of concerns”

At night, I sit down and go through each item in my daily bucket list. I empty it completely every day. You can only do one of the following things with the items in your bucket:

1. If it’s something small (less than 2 minutes) - do it immediately!
2. Can someone else help you do it? Delegate it and create an event in your calendar to follow up on it later.
3. If it requires you to be in some place and time, schedule it to be done as soon as possible.
4. If it’s some kind of information that will really be useful to remember at a later time, on some specific day … put it in your calendar (and describe it in the notes section of the event).
5. If it’s not feasible at the moment, file it to review later, under “maybe/someday” folder.
6. If it’s a huge task, create a project for it. Break it down to specific “action items” and figure out what is blocking you from moving forward with it!
7. Don’t do it at all.

3. Get inspired: Reflect and Review

1. Refocus on your priorities and values. What do you want to do with your short and fleeting Life? What is important? If you don’t have a good answer for this question, schedule aside a personal time to pray, reflect, meditate etc.
2. How about the next year? What specific goals do you have?
3. How about this week? What specifically are you going to accomplish this week? Take a look at your maybe/someday list. Can you do any of it this week?
4. What specific things you’re not doing right now that would have amazing positive effect on your life only if you would do them every day?
5. Look over your schedule for tomorrow and go to sleep. When you wake up, glance over your schedule after breakfast.

I look at every day as an opportunity to grow in all of Life. If I am not learning and growing, I am as good as dead. This is how I break it down in my mind:

Personal Areas (Inner):

• Spiritual: Prayer, meditation, reflection etc. Keep yourself from being polluted by this world. Run towards the light.
• Emotional: Emotional Intelligence, Power under control (over your emotions, thoughts, desires, speech, etc). Guard your heart. Don’t be reactive.
• Intellectual: Use it or loose it! Progressing and learning something difficult, highly technical. Using your memory so your capacity increases.
• Physical: Training your body (your temple) to be in the best physical shape you can possibly be. Watching your diet. Getting enough sleep. I learned (from Aikido) on a very deep level that mind and body are inseparable. Healthy body is healthy mind, healthy emotions.

People Areas (Outer):

• Family: spending time with family
• Friends: connecting with friends and making new ones.
• Love Life: dating, etc.

To simplify all of these things above and to understand how they all work together, you can just think of them as 3 things:

• Love: Love for Your Family, Friends, Colleagues, Acquaintances, Complete Strangers. (Agapē).
• Health: Your Spiritual, Emotional, Intellectual and Physical well-being.
• Wealth: Your ability to make money (for the sole purpose of keeping Love and Health in balance. Think about it!)

Now watch how they’re connected:

Let’s say “Love” gets out of balance: you’re not in good relationships with your girlfriend – well, it will immediately take a toll on Health and Wealth. You might be stressing out, you won’t get enough sleep (Health), and you won’t be productive at your work (Wealth).

Let’s say you’re having financial problems (Wealth) – you’re not going to have any time to spend with your family, friends and loved ones. Your relationships will start to deteriorate (Love). Because of stress, your Health will be affected as well (Health)!

If you’re sick and in pain (Health), you won’t be able to work well (Wealth), or spend quality time with family, friends, etc (Love). You need to take care of your body so it takes care of you later.

All these 3 things are connected very strongly. Keeping them balanced will make you feel great!

Instantiating objects and accessing their methods and properties:

$obj = New-Object Foo.Bar
$obj.method(arg1, arg2 …)
$obj.PropName

or shorter (anonymous var way):

(new-object Foo.Bar).method(arg1, arg2 …)

(new-object Foo.Bar).PropName

Some of the libraries are not accessible in powershell until you load them:

[Reflection.Assembly]::LoadWithPartialName(”System.Windows.Forms”)

Getting More Help

To find out more about net-object, use the “man” page (manual):

Or you could have typed “get-help new-object” (man is just an alias to it)

It’s all being shot using a very nice hi-def camera, so 10 years from now when everything is in HD, we’ll look back at it and be glad we did :) The plot of the movie is about us, and is about our training for climbing, using gymnastic rings, campusing and other methods. After showing different exercises, we are showing how they apply in real-world situations.

We’re still in the “shooting” stage capturing new footage, although we have plenty to finish this movie already. The name is to be announced soon. Reply if you have any suggestions … if we end up using it your name will be in the credits.

Powershell vs Unix Shells

The biggest difference between Powershell and UNIX shells is object orientation - Powershell deals with (.NET) objects for input/output, and Unix shells deal with simple text character streams for IO.

If you’re dealing with objects, you’re concerned with accessing its properities and sub-objects to find things, instead of grepping through text streams in a very unstructured manner.

Powershell has built-in “commandlets” (cmdlets). Think of them as built-in commands in unix shells, such as ls, cd etc. In powershell, all commandlets follow action-verb naming convention, like Test-Path, or Get-Aliases.

This naming convention is actually very emacs-like:

Open Emacs and type M-x view-[Hit Tab]. You’ll see view-file, view-todo etc.

Anyway, to make scripting for Windows platform more accessible and attractive to UNIX devs, Powershell provides aliases that map to proper commandlets. For instance, “ls” is an alias for Get-ChildItem, “dir” is also another alias for Get-childItem:

Providers

Powershell has a layer of abstraction that lets you manage different aspects of Windows: this layer is called “providers”. So, there is a provider for dealing with the file system, registry, wmi, certificate store, variables, namespaces, functions etc.

Similar to everything in Unix being a “file”, you can get a view of most things on Windows platform using right providers. It also lets you to create your own.

Great Tab Completion Support

One of the really nice features in Unix shells is tab completion. For example, Zsh (my favorite unix shell) has versatile ways you can customize tab completion.

Powershell also has a support of tab-completing pretty much everything: variable names, functions, even .NET namespaces, classes etc. There is a plugin from Powershell Guy called PowerTab. I rely on it every day … highly recommend it.

Daily Work

I try to avoid clicking buttons if I can automate it do it quicker from a command line, so my powershell console is always opened. Its great for development - I can test and script stuff using .NET without having to compile it etc, and it is also convenient for system administration in general.

I’ll post some tips and tricks on both later on …

Here is a video of him driving Evo IX MR GG (Graphite Gray), exact same configuration as mine.

Here is another one of his Evos. I don’t know about this. I think he has a very bad taste, but whatever. Its a show car with all kinds of expensive carbon junk on it (I like the clean look).

Here is a chase seen from one of his movies:

Here is more info on Jackie Chan’s Evos. I can’t read this :)

Here is a list of great food that you should just try to always keep in your fridge:

• Water - get a purifier, or drink hot tea (from real loose leafs)
• Almonds and other nuts
• Spinach
• Broccoli
• Instant unsweetened unflavored oatmeal
• Eggs (get good kind, like freerange & gressfed)
• Turkey, Lean Stake, Tuna and other Fish
• Greens for salad
• Peanut butter (increases testosterone levels)
• Whole grain breads and cereals (instead of white or whole weat)
• Whey protein shakes
• Raspberries and other berries
• Plain Yogurt, Cottage Cheese

Simple Rules

1. Don’t overeat - snack throughout the day. (OK, you already know this :) but are you actually doing it? Are you proactively preparing food for yourself so you can eat it when you’re at work?
   
2. If you missed a dinner — don’t eat one. Have a little snack at night, go to sleep and have a big breakfast when you wake up.
3. Here is a big secret: Eat fruits and nuts for breakfast, (only) carbs for lunch/day, and (only) protein for dinner. Start every meal with a salad. Carbs is the best source of energy, so you need it throughout your day. Protein is needed to repair your body for when you go to sleep. Snacking on nuts (good fat) in the morning gives you a steady long energy levels and keeps your bloodsugar from spiking.
4. Bring your own food (from the list above) to work with you so you can eat it before you get hungry. If you’re feeling hungry, it means your blood sugar has already dropped! You’ll be less productive with your day.
5. Never eat fast food, anything deep fried, processed, foods with lots of ingredients, white flour, lunch meats, nothing with hfcs (high fructose corn syrup), msg. Instead, try to eat the rawest most “first hand” type of energy sources. Plans get energy directly from sun, animals “process” them, we kill the animals and process those etc. The closer you get to the “caveman” way of eating, the better off you’ll be. Read the ingredients and stay away from foods with a lot ingredients. Simpler is easier to digest.
6. Never eat food from someone who prepared it for you in the bad mood, including yourself. I’ve always believed we extract much more then just nutrients from food. There are other things that get transported through food that scientists don’t have a name for. (prov 15:17).
   

OK, now lets break it down in high-level pseudo code. Lets assume we’re talking about arrays as a data structure.

Function InsertionSort (A):

n = number of elements in A

for i=1 to n-1:

for (j=i; j>0 && x[j-1] > x[j]; j–)

swap (x, j-1, j)

OK, that was some dense code :) It also happens to be one very bad-ass implementation of it. Lets break go through it and see whats going …

So, the outter loop:

walk from i=1 to n-1

is going to walk left to right and leave everything before i sorted, but everything it hasn’t touched yet unsorted. (you’ll see in a second why we’re starting with 1 instead of 0)

sorted pile

i

unsorted pile

The inner loop:

for (j=i; j>0 && x[j-1] > x[j]; j–)

swap (x, j-1, j)

is going to try to stick the new element into appropriate place in the “sorted” pile. The key thing to notice here is it walks right to left.

Now Visualize the inner loop:

• we have a sorted pile, with new element being at the very right of it.
• if the element to the left of it is bigger then our new element, we’ll swap them
• we’ll keep looking and seeing if the element to the left of us is smaller and swapping positions until there is nothing left.

Mergesort and merge are two separate functions. Think of merge as a helper function that does most of the work. Its much easier to explain with a very high-level pseudo code:

Function Mergesort (A):

B = First half of A
C = Second half of A
Mergesort(B)
Mergesort(C)

/* Important: B and C area already sorted at this point. We just need to merge them into A */
Merge(B, C, A)

Function Merge(B, C, A):
/* Merges 2 already sorted arrays (B and C) into one sorted array (A) */
While B and C still have elements:
keep taking the smallest element from B or C, and appending it to A

Analysis: It’s a two step process:

1. We constantly keep splitting data into two (until we can’t split it any more)
2. Then we keep merging splited pieces into a single piece.

it “Big O” is: O(n lg n) because it takes lg n “levels” in the tree to break it down, then n-times to merge them. See my refresher on logarithms if you don’t understand what lg n means.

So, thats the basic idea. Its pretty simple really. I’ll update this post and add some actual code in various languages later on. Maybe using C# and ruby.

Update: So the update worked like 4 hours later. Meanwhile, my phone was completely unusable. This whole thing is a major hit on Apple’s reputation for quality!

Base 10 Logs:

log10(1000)=3

10 ^ 3 = 1,000

Base 2 (lg):

lg 32 = 5

2 ^ 5 = 32

Binary Tree Example:

The height of a binary tree is lg num_nodes

If a tree has 16 nodes:

• common sense: its height is 4 — that’s how many “rows” it has
  
• lg 16 = 4
• proof: 2 ^ 4 = 16

So, as you can see … as n grows rapidly, lg(n) is growing very slowly. Why is this important? Its important in computer science, were we are always concern with what happens to our program when the data it processes increases. What happens to its speed if input data is of enourmous size? Will the algorithm choke?

As n approaches infinity … what happens to it? A lot of algorithms in computer science have this logarithmic properity …

(I’ll update this after I post some sorting algos)

To make cmd.exe more unix-like, do the following:

1. Create a shortcut:

2. Create Profile.cmd with contents:

@echo off

prompt [$p]$_$g

doskey ls=dir $*

doskey ll=dir $*

doskey cat=type $*

doskey ..=cd..

doskey grep=find “$1″ $2

doskey mv=ren $*

doskey rm=del $*

doskey pwd=dir

echo Environment is set

-

Better yet, forget about it and just start using Powershell. Thats where its at! It already has aliases for both Unix and Windows commands, corresponding to the proper Powershell built-in commandlets.

Hagakure is a very interesting book I picked up — it has a lot of historical value since it describes life during ancient japan, when the shogun and samurai ruled the country. I’ve been a student of Aikido and other martial arts for some time now, so this is very interesting to me. Some of the stuff in this book is too wild and gruesome to mention but I thought these quotes were great.

“To give a person one’s opinion and correct his faults is an important thing. It is compassionate and comes first in matters of service. But the way of doing this is extremely difficult. To discover the good and bad points of a person is an easy thing, and to give an opinion concerning them is easy, too.

For the most part, people think that they are being kind by saying the things that others find distasteful or difficult to say. But if it is not received well, they think that there is nothing more to be done. This is completely worthless. It is the same as bringing shame to a person by slandering him. It is nothing more than getting it off one’s chest.

To give a person an opinion one must first judge well whether that person is of the disposition to receive it or not. One must become close with him and make sure that he continually trusts one’s word. Approaching subjects that are dear to him, seek the best way to speak and to be well understood.Judge the occasion and determine whether it s better by letter or at the time of leave-taking. Praise his good points and use every device to encourage him, perhaps by talking about one’s own faults without touching on his, but so that they will occur to him. Have him receive this in the way that a man would drink water when his throat is dry, and it will be an opinion that will correct faults.This is extremely difficult.

If a person’s fault is a habit of some years prior, by and large it won’t be remedied. I have had this experience myself. To be intimate with all one’s comrades, correcting each other’s faults, and being of one mind to be of use to the master is the great compassion of a retainer. By bringing shame to a person, how could one expect to make him a better man?”

(From Yamamoto Tsunetomo, “Hagakure”, The Book of the Samurai, 1716)

I guess its time to get strong on gymnastic rings again!

[update] I did get strong on rings and  now I am climbing way harder! Sweet.

My friend Adam Heley came over from Portland with a bunch of his buddies, including Boone Speed. Johnny (Goicoechea), Lena, Cole, Kyle, and Joel Cambel were already there when I got to L-town. Later on that day we ran into John from EPIC (EWU) program and like 10 other people from Spokane.

I’ve never seen that many monkeys at Leavenworth campgrounds before. Boone took some awesome pictures, Johnny, Cole and Joel went climbing at some new area they recently discovered. We all had fun and partied afterwards at the camp ground. Too bad I had to leave early in the morning to help my friend move.

Just try it! It won’t work. Does anyone know why though?

Delegates are kind of like a C function pointer, and they’re even more like C++/STL functors. Except for the following distinctions:

1. They’re safe
2. They also have a multicasting feature. Unlike a C function pointer, you can subscribe multiple callbacks to the delegate. Whenever you invoke a delegate, in return it will call all subscribed methods. More on this later.

So, the whole GUI system in Java or Windows Form is all based on events. It’s also called the “observer” pattern. So, it’s important to get events/delegates mechanism down. In this very simple example we’ll have a Broadcaster and a TV. The broadcaster “fires” and event and everyone that is subscribed to it will get it.

I like to oversimplify things, so to break it down from each side.

The broadcaster:

• Defines a delegate. Basically it’s syntax is like defining a function prototype in C. The functions the will be subscribing to us will need to have a matching signatures.
• In order to use a delegate as an “event”, we need to attach it to a class with an event keyword.
• The broadcaster will have a “fire” method. First we make a defensive copy of the event, to avoid a possible race condition. Second, we check if its null (no one is subscribed to us yet). Then we call it. By calling a delegate (once), it calls all of the subscribed methods in the order they were attached. They way it works is delegate keeps track of all the functions that are subscribed to it. You can access them by del.GetInvokationList().

The TV:

• Just has one method, nothing special, no special keywords. But … this method’s signature is the same as the delegate’s.

The Program Driver:

• We create the Broadcaster and TV objects
• We fire an event from broadcaster, no one is listening at this point
• We attach a bunch of listeners to broadcaster
• We fire again and watch what happens

Things to note:

• We can attach any method to a delegate with += operator. The only requirement is the method has to have the same signature.
• In broadcaster.fire() by calling on a delegate, we’re invoking the chain of subscribed methods. Some of them are anonymous. Watch for the output and how .NET names them. Its interesting.

I was going to continue running my own business from Seattle, but decided to take a job offer form Microsoft -- it seems really fun and its a totaly different environment then what I am used to (me).They are treating me very very well. I have to say ... MS has the very best coffee I've had anywhere! Thats really good because I am a coffee addict.

I also found an awesome apartment right in the middle of downtown, in a brand new building. I am the very first person to live in it. It has a downtown city view and I can also see the Ocean.

Its on the top floor (penthouse), plus I have a ruff access where I can chill and work. It really couldn't be any more perfect. I am making lots of friends and enjoying life.

Oh, my cell phone has changed.

FreeBSDI was very impressed with how small the default OpenBSD install was, and how well organized and clean the file system layout and all the configs were. The only complaint I had was the lack of software that I could get on Linux, especially multimedia, like playing movies and watching TV (I had a TV Card). OpenBSD is targeted more towards servers and security, less towards the end-users.After a while, I discovered FreeBSD! FreeBSD was the logical choice for me. It has everything I like about OpenBSD, plus thousands of programs to choose from. It is a beautiful system. It is the cleanest, most well-designed and engineered of all operating systems in my opinion.Any time I'd try to go back and use Linux (after using Mac OS X 10.4 "Tiger" and FreeBSD 6.X), it would feel like a hack job to me.

I really like the FreeBSD file system layout, their package management, ports, awesome documentation. A lot of FreeBSD development comes from Russia and Japan so they have great localized support and translations for all manual pages, handbook, howtos, and shell commands. I could make everything be in Russian, just by setting my login user class to by of type "russian".Linux really isn't an operating System ... at least in the FreeBSD-sense of the word. "Linux" is really just a Linux kernel.A Linux distribution is a bundle of Linux kernel, GNU-based commands and utilities, some form of package management (deb, rpm) and X11 with some window mangers.The FreeBSD, in comparison, is just one. Its not separated in all of those different components, and the whole thing is under source control.

There is only one FreeBSD Kernel, only one set of BSD commands and utilities (userland), packages and ports, documentation and way of configuring things. FreeBSD development is either in stable or current tree. You can sync to either one you like, or just use snapshots of the “stable” tree, also known as "releases". Everything in FreeBSD is tracked under source control, including kernel, userland, system manuals and documentation, so you can just pull the latest sources and recompile the whole system (and kernel) by typing “make world”. I really like that about FreeBSD. It is engineered, not hacked and pieced together! To recompile a kernel you simply "make kernel"!

Ubuntu: Anyway, back to Ubuntu. So, I was kinda disappointed with Linux distro's for a long time and I'd never consider switching to it from FreeBSD. I have Toshiba Satellite A105 S4134 Laptop dual booted with FreeBSD and Windows XP. I use both operating systems as development platforms. I don't ever play games ... etc, but I do need WiFi and sound. After many attempts, I gave up on trying to get my built-in WiFi card to work on FreeBSD. Eventually, I did get the sound to work with the comercial Open Sound System (OSS) driver, but the native FreeBSD 6.x drivers didn't have support my sound card.Here is my impression of Ubuntu: It is Stunning! It is sooo easy to install and use. I couldn't believe it. I also have a 2 Macs installed with OS X 10.4.I was surprised to see that Gnome is actually catching up on GUI usability and KDE has really cool graphics and effects, similar to Aqua's (Mac's proprietary windowing system, they don't use X11).

Anyway, I put in the installer CD, and it started with a very nice logo. After that, it detected my video card and a USB mouse, X11 started in full-resolution and played a welcome sound! My WiFi card was also detected right out of the box. I was so impressed!I spent hours trying to get that stuff to work on FreeBSD, recompiling the kernel with all kinds of tweaks ... etc.The installer is also a "live" cd. It lets you play with all the stuff you'll get without actually installing the system. So, I erased my FreeBSD partition and reformatted it with ext3. I didn't need swap since this laptop has like 2GB of RAM.The installer went very smooth. Everything worked and it didn't mess up my Windows XP partition.

After I rebooted, Ubuntu offered me a list of available updates! Even though I am a developer, unlike all of my friends, I don't like to mess with configurations and the system itself (unless that is my goal). Most of the time I have very specific things I am trying to accomplish and I just want my computer to work! I am just another user. I just want to spend my time writing software and I want all of my tools to work and be available to me immediately if I need them.So, out of the box I had everything I needed:

• OpenOffice 2.0
• FireFox (SwiftFox, optimized version)
• Evolution
• JDK 1.5, Eclipse, ant
• Compilers, Interpreters, and other Dev tools.
• Automatic Software Updates (for the system itself and all the packages)

The sound card, video card, USB, bluetooth, power management, DVD, and CD-burning works! On FreeBSD I only got the video card, sound and usb to work. I am VERY satisfied with Ubuntu, and I am actually going to keep it! Every piece of hardware on my laptop was detected and everything is working perfectly!Thanks to Ubuntu project, awesome job!

• Super fast and responsive, unlike most java software
• Modern interface with Java5/Swing!
• Modern language with much larger (lang) user base
• An easy-to-use Plugin system that actually works! It can do self-updates, checks dependencies, versions.
• Code completion, "intelli-sence" popup helpers ... etc, modern IDE stuff!
• Code Folding and Comment Folding
• XML for configs, instead of elisp (trust me, I love elisp more then you do)
• Multiplatform
• Unified Development (like FreeBSD haha, there is only one jEdit. Penguins make tasty snacks.)

I loved the default jEdit functionality, but emacs key bindings are so engraved in my head, I can't use anything else. By the way, Mac OS X uses emacs shortcut keys on all of the programs! I love OSX. Anyway, back to the topic.So, with a little bit of customization you can make jEdit behave just like Emacs. On the mac, there is a weird meta keys are bound to Opton key by default. I don't particularly like that. So, what I did is I rebound Meta-key to Command key ("Mac" symbol key).LooksBeing emacs fans, we don't like to use mouse and click buttons more then necessary. So, I don't need a permanent button bar that just takes up my screen realestate. OK, my mac laptop screen is like 17 inches but thats not really the point. You can go to preferences to remove it. To do the same in emacs, add this to your .emacs:

Remote EditingWhen I use Emacs, I pretty much always have "dired" mode open, angle-ftp, and TRAMP mode. With tramp, you can remotely edit files over top of ssh, ftp, sftp, webdav and emacs transparently handles saving changes, uploading files and other operations. jEdit actually has the same feature that works even better. Its faster and it doesn't hang on sftp sessions at random times. Its called 'FTP' plugin, and it also works over sftp. One nice thing about it, is that it remembers your username/password and the last files you accessed.Language SupportIt has support for over 150 languages, including folding of comments, heredocs, weird language constructs parsing etc. In emacs a lot of things originate from cc-mode, which explains why syntax coloring doesn't render correctly. Oh, if you're into ruby, it has a super-nice ruby plugin you should check out.Screen Shots

Cake is a mature MVC framework with a large user base, excellent tutorials and API documentation. Scaffolder is a tool that generates website forms and pages for you, by looking at your Database schema. Most web MVC frameworks have a scaffolding feature and they typically generate add, edit, delete, and list functionality. This lets you quickly get things up and running.The very first step in scaffolding is generating a "model". A Model (M in MVC pattern) is an object representation of your sql table. Thats too vague ... what does it all mean? Well, if its in PHP, then you might have a Person class (that inherits from AppModel) that is bound to "people" table.

Or in RoR, you have a Person class (that inherits from ActiveRecord::Base) that is bound to "people" table:

In the second step, you tell the scaffolder how your models are related. Some of the relations could be described as:

• A has_many B (Person has multiple email addresses)
• C belongs_to D (email address belongs to a person)
• E has_and_belongs_to_many G (E permission has and belongs to many G Roles)
• X has_one Y (wife has one husband, vise versa)

In cake, the scaffolder is in 'cake/cake/scripts/bake.php', and in RoR there is 'scripts/generate'. Cake's scaffolder is more interactive, as in it asks questions while it runs. It understands relationships between models. The RoR scaffolder is also a command line tool that takes a bunch of arguements and don't really asks any questions when it runs. The default RoR scaffolder is simplistic and doesn't generate pulldown menus ... etc, for models that are related to each other. Cake's default scaffolder does.

For instance, if you people and emails table, it will generate a pull-down menu of people inside emails add and edit screens. There are many scaffolders available for RoR, that generate pretty views and know how to handle complex relationships. RoR is way more comprehensive than cake, especially when it comes to scaffolding. One of the "alternative" scaffolders you can get for RoR is AjaxScaffold.

Model (ActiveRecord vs ... nothing?)

In web MVC frameworks, a model typically is an implementation of "Active Record" pattern. Ruby's ActiveRecord gem (package) is an object to database table mapping, kind of like DataTable in ADO.NET (yuck!). For instance, Person class is mapped to people table. You can access person.emails, delete a person with person.destroy ... etc, set a person's name with person.first_name = 'Dmitry', person.save.
