Correct me if I'm wrong, but this is how I learned it.
The only reason a bubble will ever stay intact is if the surface tension is even, with all bubbles on earth that are liquid. No one start on me about glass:P).
The reason bubbles pop is due to gravity pulling the liquid down, causing a collection at the bottom in the case of light bubbles. The air stays up, the liquid wants to go down. Since liquid is liquid (liquidity!) it collects at the bottom of the bubble. So you have 3 forces contending. Gravity pulling down, surface tension and the air inside preventing it from becoming a drop of water.
Eventually, the liquid gathers at the bottom. Air can't escape yet 'cause it's a bubble. The liquid gathering on the bottom is from the surface of the bubble.. The surface of the bubble becomes thinner until it can't hold. Then, pop, it falls down (not outward).
I hate to tell you this, but "first post" has been around for a while. If you think about it, you are prolyl like, the 500th person getting "first post".. which sorta makes you 500th post.
Not really. Sometimes security provides freedom. I.e. I'm free to vote, and security prevents people from taking that away. People can't (shouldn't be able to) vote for me, I can't be physically detained from voting etc etc..
In truth, security can have any varying affect on security.
Depends on the account you are talking about. It soundslike you are talking about outsourcing to a vendor. CMM takes into account trends in a company, so if you outsource to a vendor that doesn't know what they are doing and you cancel things/w them due to incompetence, well.. taht's one thing. If you integrate working with them into your process..well.. that's another.
Well.. to be more nitpicky, you sometimes NEED to go by standards. What if the gov't required you never to store a credit card number ever again? Then you are redesigning because someone told you, you need to. not a business reason. I can give you references in books about this if you'd like:)
Also, processes implementing the CMMs are highly company-specific, which add an even higher learning curve and training burden for developers and managers. Imagine, in the family scenario, having peer reviews and QA meetings for each meal served, the greenness of the yard, why isn't Jimmy doing well in Algebra, etc. while keeping written records of it all for accountability and future analysis. For small teams, it is very possible for this sort of process to interfere with getting real work done.
Realize, checking Jimmy's homework, everyone eating at a certain time.. that's all bureaucracy. Yes, SEI is the only one who can grant CMM levels, but I'm trying to drive the point, that CMM can apply to any group, even without SEI's blessing. Just the validity of it is what's questioned, eh?
I feel it is very important to separate the bureaucrats from the developers while imposing as little (or, at least, transparent) process on the developers as possible to satisfy whatever documentation and metrics gathering are needed. This is where bureaucracy can be helpful without being overbearing: developers can develop without needing to worry about formatting meeting minutes, making travel reservations, administering their own bug reporting system, etc. For small groups, however, this bureaucracy is very hard to afford--and the CMM breaks down.
Ah, but everyone is a bureaucrat in one way or another. If the amount of people are small, you don't need a big process.. but you might need one none the less. Even between two people. Unless they are best friends from childhood, they won't work together like psychics. It might be an inbox, a file cabinet, an email system.. SOMETHING. And if those 2 people can accomplish what a 100 person company can do, both can be at CMM 3,4,5 or 1. Just a matter of how well they work and consistent they are, eh?
Erm, do you *want* to work in an environment where your work ("the process") is highly repeatable? Where's the fun in that?
I like having hair colour;)
Seriously tho, these kinds of "process" thingys always give me the impression that they are implemented (and followed) in places where the management hasn't got a clue; in places where management believes that the "workers" don't have a clue; in places where the management believes that an employee cannot possibly *want* or *enjoy* his job, and has to be policed at all times.
Well, it's the difference of having no law, some law and too much law. Then add consistency to it. Process is there to prevent people from shooting themselves in the foot../mostly/.
I rather have management say, ok,it's time for a code freeze, QA gets the code, they do their thing, then another step, then another and then it's live. It makes my margin of error smaller, since things are done in a consistent manner. It doesn't stop me from being an architect. It just means there are some laws in place.
ANd btw, if there's an opportunity to improve something, it doesn't mean i can't recommend it to biz people to include in a project. It's an opportunity a system analyst would include.. if they were smart.
I'm pretty convinced that any project with one or only a few developers is CMM Level 1, regardless of what the CEO brags about. The CMM implies bureaucracy, where there really needs to be additional people on staff to handle all the documentation. Other people are needed to enforce the process. There also needs to be extra managers to handle all the new communication overhead. Don't forget the payroll people to handle all the new accounting practices. Oh, and there's the system administration overhead of all those CM tools.
I'm pretty convinced that the CMM is relevant only to those companies big enough to rival governments in sloth and politics, where some rule of law, essentially, is needed to keep everything moving forward.
It's relevant to a group, a company usually. If you have 10 people doing a particular job, say.. those people who make cell antannae that look like landscape objects (trees, etc..). If their process is higly repeatable and optimized and are looking to improve, they'd be at 5. If any other factors holding them back aren't there though.
Your family can be at CMM 5, if you can get your kids out the door, laundry done quickly, etc, and are looking to improve. But usually, family doesn't work like that. It's usually chaotic since family isn't a biz.
No, not really. CMM isn't about coding at all. Hell, it doesn't have to be about technology. It's just about doing N steps, from 1-N, in a fashion.
If your coding process was at level 4 or 5, that means the segment is going for optimization and is highly repeatable (wrote that backwards).
Saying any individual coder is at CMM 4 only works if one person is the entire process. This doesn't work in the biz world like that. Great, a person capabale of working at CMM 5 will only be brought down to 1 when put in a CMM level 1 company. It's not about individuals, it's about a group, like your grunts, doing something.
Btw, is "codify" really a word? Automating your process doesn't mean you'd have borked products. Means you do something that works really well and are improving gradually.
CMM is a tool for identifying process ability, not code quality. i.e.
Someone at CMM 1 would be totally chaotic. Think waterfall on crack, skipping about back and forth randomly, developers coding on the whim of people.
At CMM5, there's be a strict set of policies (1 or 2, maybe more) that are repeatable, managed and are being optimized.
To say that developers across seas bring about CMM 3 or 4 is saying nothing. CMM isn't about one type of people, much less any people. It's about process a group uses to deliver. If they mean consultant companies across seas have higher CMM, maybe, but I'd think the language barrier would slow things down.
I think you're missing the point, you don't redesign solely for the purpose of becoming standards compliant.
Of course you can. It's called an opportunity. For instance, I work at a place that wasnt' ISO country code compliant. We fixed our databases so that we can later open ourselves to use other ISO country code compliant software. Nothing was particularly broken.
All that's need for any system change is either an opportunity, a requirement (thing gov't) or a request (think biz).
What about a gov't requirement to purge certain data?
I know, it sounds like knitpicking, but it's the truth:)
I was sitting in my bedroom, about to go to bed, listening to my iPod. I put the timer on 30 minutes, hook it into my headphones and hang them over my bed. Nice to fall asleep to music sometimes.
Well, I put it down in a drawer, so I won't smack it off the table and turn off my lamp. The coolest thing ever happened. My drawer looked like a treasure chest with light pouring out a-la "Zelda 64" when you get a big chest.
Points of this story?
- The iPod makes for a good flashlight. - Yes, It runs linux.
You do realize, that even if there was one world language, that everyone understood by tomorrow, given enough time, dialects would sprout, then entire new languages?
Not really. Can you cheaply create a cluster of say.. 50 web servers, all that use mod_gzip for line compression?
Xeon's arent' THAT cheap, but hey, 1ghz machines (or even 500mhz machines) with this card would easily match your Xeon once the 64MB/s cards come out. Or was that 64mb/s. Well, you get the point.
As for the bus latency, well.. you are right, it'd be better in the network card, but remember, that's layer 1 and 2 stuff you'd be meddling with, where gzip would end up in layer 4. Layer 3 is tcp/udp, 4 is app data, right?

Nuts. I guess we all have to wear headphones now.
Not a lawyer, but I doubt keeping even a company bought CD, copying it to a HD, and have it ready for multi-user playback can hardly be legal.
If it were played in a form, simliar to a radio, that everyone listens at once or not, like a broadcast, that might be more legal.. but even then.
'sides.. go ask a lawyer.

Cheap is in the eye of the beholder. My college education is cheap, but to all those who can't afford to go, college across the board is expensive.
So functional, robust and cheap can be done... just depends on what side of the fence you are on.
