The martial art style Judo can mean a lot of things to different people. In reality, it is a fun and exciting sport, an art, a discipline, an activity, a way to protect yourself, and quite simply a way of life. Although you may hear many different meanings, the word Judo actually means all of the above and several more.
Original founded back in 1882, Judo comes from the feudal Japan fighting system. Upon founding, Judo was a refinement of the martial art jujutsu. Jujutsu is one of the oldest martial arts styles, dating back hundreds of years.
Judo made the biggest impact in 1964 when it was first introduced into the Olympic Games. Now, it is practiced by millions of people all across the world. Judo can help students stay in shape, excel in all areas of competition, stay protected with self defense, and several other things. For a majority of students, Judo is practiced just for fun. Although it starts out as fun for many, it quickly turns into a way of life, a burning passion if you will.
Similar to other martial arts styles, Judo has rules that ensure the safety of those competing in the competitions. Students of Judo who are looking to test their skills will enjoy the competition levels, which range from club meets to national tournaments, and on up to the well known and best level of competition - the Olympic Games.
Judo is known best for it’s amazing throw techniques. What many aren’t aware of, is the fact that Judo is more than just throws. It also involves grappling on the ground, controlling holds, arm locks, leg locks, and even choking techniques. Judo teaches all aspects of self defense, from a grappler’s standpoint.
Another great thing about Judo is the fact that anyone can study, male or female, and even those that are disabled. Judo is also inexpensive to participate in, taught throughout the year, and it appeals to everyone. This martial art is also unique in the sense that even the elderly enjoy practicing it on a daily basis.
Judo also helps students learn and develop respect and self discipline. It offers the chance to learn self confidence, leadership skills, power, flexibility, and physical prowess. Judo has evolved quite a bit over the years, going from a fighting art to competition status. These days, there are separate Judo ranks for kids, adults, and seniors.
The martial art Judo, which means “gentle way” teaches you the applications that you need for self defense as well as competition. Judo is unlike other martial arts, in the sense that it combines the best of grappling with awesome throws that require little to no strength - but more of the way you position your body. This is an excellent martial art - that anyone can enjoy.

Passing the BSCI exam and earning your CCNP is all about knowing the details, and when it comes to EIGRP SIA routes, there are plenty of details to know. A quick check in a search engine for “troubleshoot SIA” will bring up quite a few matches. Troubleshooting SIA routes is very challengin in that there’s no one reason they occur.
View the EIGRP topology table with the show ip eigrp topology command, and you’ll see a code next to every successor and feasible successor. A popular misconception is that we want these routes to have an “A” next to them - so they’re active. That’s what we want, right? Active routes sound good, right?
Well, they sound good, but they’re not. If a route shows as Active in the EIGRP topology table, that means that DUAL is currently calculating that route, and it’s currently unusable. When a route is Passive (”P), that means it’s not being recalculated and it’s a usable route.
Generally, a route shown as Active is going to be there for a very short period of time by the time you repeat the command, hopefully that Active route has gone Passive. Sometimes that doesn’t happen, though, and the route becomes SIA - Stuck In Active.
A route becomes SIA when a query goes unanswered for so long that the neighbor relationship is reset. From experience, I can tell you that troubleshooting SIA routes is more of an art form than a science, but there are four main reasons a route becomes SIA:
The link is unidirectional, so the query can’t possibly be answered.
The queried router’s resources are unavailable, generally due to high CPU utilization.
The queried router’s memory is corrupt or otherwise unable to allow the router to answer the query.
The link between the two routers is of low quality, allowing just enough packets through to keep the neighbor relationship intact, but not good enough to allow the replies through.
To sum it up, routes generally become SIA when a neighbor either doesn’t answer a query, or either the query or reply took a wrong turn somewhere. I told you it wasn’t the easiest thing to troubleshoot!

When it comes to silly party games, it seems unfair that birthdays get all the attention and Christmas none. It’s time to bring back some silly party games for Christmas, and “Pin the beard on Santa” is as good a place to start as any.
To begin this game, you need a cardboard cutout of Santa. This can be purchased at some party stores, or even little gift shops. It doesn’t have to be large, but it should be a big face of Santa. You can also find these at educational supply stores, or teacher supply stores, in the section of other cardboard decoration items that teachers put on classroom walls.
Once you get Santa’s face home, cut off his beard. That’s right, cut if clean off. There’s no point in pinning Santa’s beard on him if it’s already there, right? The beard you sliced off can either be thrown away or keep it to tape back up later, if you want to use Santa’s face for another game or as decoration.
Now, you can create several beards out of different items. It’s easy to take a piece of thick cardstock and cut the beard out of that, or you can use foam with adhesive backing. You can simply peel the backing off right before it’s used. You could also make the beard out of crumpled white paper, simply computer paper or the like. If you want to get a bit more elaborate, create Santa’s beard out of cotton balls or a large piece of cotton pulled and shaped into the semblance of a beard.
If you have 5 people playing this game, you’ll need 5 beards. 10 people? 10 beards. You get the idea.
You play “pin the beard on Santa’ exactly as you play “pin the tale on the donkey” and similar games. Spin the person around, make sure they are blindfolded and then have them try to replace Santa’s lost beard. Self-adhesive foam works well because once they place it on the picture of Santa, it’s not going to move, so they can’t change their blindfolded mind and change the position once they pick a position. It’s there for the duration.
No, you can add several variations to this game. For example, you can buy a full-size cardboard Santa (again, the party stores often have these, or school supply stores, or you can make one of your own without much effort). You might have people pin the boots on Santa, pin the hat on Santa, or pin a red button nose on Santa.
One fun (adult) version of this game is to pin the chest hair on Santa. Create a fun cardboard Santa with his suit unbuttoned. It’s a big macho for Santa, but also a bit fun. Then fashion “chest hair” out of yarn, threads or fake fur. Attach some sort of adhesive to the back (foam stickers work, or heavy-duty double-stick tape) and have people try and pin the chest hair on Santa the same way they attached his beard or might attach his boots.
Any good game offers a prize for the winner, and this one is no exception. You could always offer Santa to the winning ‘pinner” or you could have something more elaborate like a Santa goodie bag, filled with Santa pencils, Santa erasers, a Santa coffee mug, and Santa-themed candy.
