Retro Dude Review: Power Blade

Lets go back in time. This time we are counting 1991, only one year prior to the great SNES release in Europe. There was a game developed by Natsume, published by Taito, known in Japan only as Power Blazer, but to many others around the world as Power Blade. It had action, it had a super master computer, it had explosions everywhere, boomerangs, powerups, burgers and a kickass soundtrack that still to this day amazes me with its pure awsomeness. ( The graphics where almost unheard of and my little six year old mind was blown to pieces.

(Insert corney picture with sister below)

The game starts you out at the introscreen (Duh) where you get the options to either start the game in either normal or Expert mode, or continue using a code gotten from previous levels. But you gotta pick fast, and I do mean fast because it takes the intro sequence literally two seconds to start.

During the intro you get the backstory of the game.

In the year 2191 the earth has left all of its power in the hands of the infamous Master Computer and is now living under a Terminator, Skynet like control, and like in the not so related movie the machines decides that there is no longer any need for humans and goes haywire and tries to take over the world. 

It's now up to you. Nova the security-chief to set things right. You are told, by your boss. To go out and search the 6 sectors to find agents that are holding security-keys (one agent and key per sector) to unlock the doors that holds the defence robot that protects the Master Computer located in Sector 7, all while you watch your ass or backside, since this is a nes relase and we don't want any swearing.

You push start and then you get to the sector select screen. luckily they made this game like megaman so you get to choose which sector you want to start out in. The only one locked is Sector 7 since that is the one you are trying to get acces to. So lets talk about stages. The first stage starts you of at the bottom of a spacerocket that you have to climb to get to the boss and agent. It's pretty straight forward actually. Word of advice at the beginning of the stage. When you climb up the first ladder you can jump down on the platform to your right to get the awsome powerup. It will give you an android like appearance and a super weapon. Like I said when you get to the top you reach the first Defence robot or the Boss, if you prefer that term.

Now let it be said that even though the graphics is awsome, the sound is epic 8 bit art and the stages are extremely well thought out its all just to easy and you wont get to many problems anywhere in the game especially with the first boss. It's this white robot with a big gun that dosent do much of anything. He shoots his gun goes right, left and jumps over you. That might sound hard but everything he does is like in slow motion and it's way to easy to predict his moves. Besides by the time you reach him you got all the powerups and as long as you remember to dodge his slowmotion, small, wanna be bullets you will be just fine. You win the stage, get to the mainframe, turn it off and you continue to the level select screen.

The second stage is windmill heaven for some reason, but as a Dane I can't stop smiling about that one. And here is where the whole maze like stages sets in. If you got a little jump skill the stage is rather easy but I don't wanna spoil the game to much it's better you play it yourself. Just let me tell you this. There will be waterfalls, gears, the windmills, slugs and frogs that explodes for some odd reason I still need to figure out. The boss is a Dragon-robot that transforms into a fire spiral and it puts up some challenge until you figure out its pattern. It also shoots fireballs but just dodge those and you will be fine.

That gets us to Sector 3. How to explain this one I got no idea since it's bagground changes to everything from a futuristic look, a swamp like appereance to some sort of lava melting, moss thingy. It is all basicly just a little disturbing to say the least, and to top it all of the boss is a freaking robot bee hive. I mean what the fuck where they thinking here? I don't even know. It puzzles my mind even to this day.

Now Sector 4 is a half build skyscraper if anything and it can be tricky to get the hang of. Just make sure you get to the freezer room before you atemp the high climb towards the top of the building and you should be fine. The only real though spot to speak of is where you gotta jump from these moving platforms, where one mistake will send you hurling down to the ground, and nobody wants to clean up after that mess. The boss is this wanna be Thor the thunder robot god, and it is hard to tell the difference  right?

Well maybe not that much, and what is with the finger is he an E.T. or a thunder god? Either way aouch.

And that brings us up to Sector 5. Sector 5 has always for some reason been my favorite level in the game. The maze effect isnt really an issue here and almost the entire level is played out on an orange ship. The boss is this genie (and I don't mean the cute disney kind) like robot that disappears and pops up again at random while shooting bullets in all directions, and even though it's my favorite level there isn't really much else to say about it.

Sector 6 Takes place in a straight line with the city in the bagground. You can get into the sewers bellow by the ladders spread out on the road. Then you reach the main building that just reminds you once again of the mazes that's in this game. The boss is this huge android guy surrounded by platforms that appears and disappears like in Megaman. 

And then we got Sector 7 the last and final stage in the game. Now since this is the final game I won't tell you anything about it since I dont like to many spoilers in my everyday life so why should you? That is also the reason I have left out many things yet to be said about this game. All I will say is this.

If there ever where an all time favorite for the NES in my heart it will always be and always has been Power Blade. The Graphics is awsome the soundtrack I can still listen to with great joy in my heart, and the gameplay is solid. The only bad thing to say about this game is that it is to easy! You can complete it in 30 minutes or less if you have done it before. Even the expert mode dosen't leave you with much since the difficulty is the same, the only difference is that, the time you have to complete the stages is 350 seconds instead of 999 seconds. But that is all I'm going to say about this game. I'm going back to my controller to enjoy my childhood one more time.

Retro Dude saying goodbye and I do hope you get a chance on playing an instant classic!

Sadly this time alone  ;)

Gnu Privacy Guard (GPG) introduction

1. what is gpg?
GNU Privacy Guard (GnuPG or GPG) is a GPL licensed alternative to
the PGP suite of cryptographic software.

2. where does it used?
excerpt from wikipedia [3]
Although the basic GnuPG program has a command line interface,
there exist various front-ends that provide it with a graphical user
interface. For example, GnuPG encryption support has been integrated
into KMail and Evolution, the graphical e-mail clients found in KDE
and GNOME, the most popular Linux desktops. There are also
graphical GnuPG front-ends (Seahorse for GNOME, KGPG for KDE).
For Mac OS X, the Mac GPG project provides a number of Aqua
front-ends for OS integration of encryption and key management as
well as GnuPG installations via Installer packages. Furthermore, the
GPGTools Installer installs all related OpenPGP applications (GPG
Keychain Access), plugins (GPGMail) and dependencies (MacGPG) to
use GnuPG based encryption. Instant messaging applications such as
Psi and Fire can automatically secure messages when GnuPG is
installed and configured. Web-based software such as Horde also
makes use of it. The cross-platform plugin Enigmail provides GnuPG
support for Mozilla Thunderbird and SeaMonkey. Similarly, Enigform
provides GnuPG support for Mozilla Firefox. FireGPG was
discontinued June 7, 2010.

2. should i use it?
excerpt from the kernel discussion [1]
There is going to be discussion about security procedures at the kernel
summit; to date we've been focused on the short-term requirements to
get back up so that the next merge window can open up,
hopefully without getting instantly compromised again. That's going to
require the help of everyone that we trust, especially from folks who
are maintaining git repositories.

I personally don't think we're headed into sign-all-patches, since
patches still need to be reviewed, and at some level, as long as the
patch is reviewed to be Good Stuff, that's actually the most important

That being said, if you have a GPG key, and you can participate in a
key signing exercise so that you are part of the web of trust, that also
means that you have a much better ability to trust that git trees that
you pull down to your system that have signed tags are in fact
legitimate (at least up to a signed tag).

So there are good reasons why developers who primarily participate
by e-mailing patches might want to start using GPG.

3. how long should the new key be valid?
excerpt from the kernel discussion [1]
That is a good question. At the very least you want it to be valid for
long enough that you will be able to get enough signatures on a new
key *before* your old key expires. As such I would recommend 3-5
years depending on how much you trust yourself to keep the key

Some people have decided to opt for an unlimited key, but that
*requires* that you have a way to revoke the old key, which is why we
are considering a key revocation escrow service.

4. what tools do i need to generate a gpg key?
well, you need gpg. To generate the key,
$ gpg --gen-key and follow the steps on screen.
you can read for more information in [2]




1. what is kerberos?

from wikipedia,

kerberos is a computer network authentication protocol which works on the basis of 'tickets' to allow nodes communicating over a non-secure network to prove their identity to one another in a secure manner.

okay... so what it actually means?
It means in a network, a client computer authenticate to a server and this process mutually prove the identify of the client and the server respectively.

A 'ticket' is produced if the identity is authenticated and authorized. This ticket can be used by client to access the computer resources that it allowed to.
2. how does it really works?

Imagine with two computer, server A and client B. server A and client B is connected together in a TCP network. Now client B need to access a computer resource, which require authentication.

Server A provide the service of authentication over the network. Now client B will authenticate itself to the Authentication Server (AS). This username will be forward to a Key Distribution Center (KDC).

The KDC issues a Ticket Granting Ticket (TGT). TGT is produced with a time stamped, encrypt it using the user password. TGT will be return to the users' workstation.

If client B need to communicate to another node (kerberos coin it
'principal'), it send the TGT to the Ticket Granting Service (TGS). TGS shared the same host as the KDC. If the TGT is verified valid, then the user is permitted to access the requested service in the node. TGS will issue a Ticket and session keys to the client.

3. where does it used?
windows domain controller or in samba. Basically any service that support kerberos authentication.

4. should i use it?
That depend for a few factors. for one, if you are administrator for a organization which has many computer resources, you want to provide single sign on for the user. That is, once a user is authenticated, the authenticated user can access to the resources it allow it. Then in this situation, it may sounds logical to implement kerberos into the network authentication service.

5. any link for me to read further?
sure, i find the below is useful." title="" title="" title="

Hello world!

Now from wordpress!

The blogs from Jason and I are still going to be about IT hard and software.

We both run gnu/linux and use lot of opensource software, so many post and review are going to be on that topic.

Hope you will enjoy our post

Best regards
