Will the Google Car Turn Out To Be the Apple Newton of Automobiles?

Ichijo Re:How hard is it to recognize a stoplight? (283 comments)

Since it cannot reliably detect when children are present, it would most likely just default to the lower speed.

And then be pulled over for obstructing traffic or otherwise being a traffic hazard.

Will the Google Car Turn Out To Be the Apple Newton of Automobiles?

Ichijo Re:How hard is it to recognize a stoplight? (283 comments)

I'm interested in whether the car can set an appropriate speed when it comes upon a sign saying "Speed Limit 35 When Children Are Present" or "...When School In Session", and whether the car can read and obey hand signals, and whether the car knows right turns are prohibited at a particular intersection during rush hour.

FTDI Reportedly Bricking Devices Using Competitors' Chips.

Ichijo Re:Is this legal? (688 comments)

This doesn't hurt the people who created the fake, or even the people who purchased the fake and used them in their manufacturing. It only hurts end users who have done nothing except purchase a product in retail channels.

Bad reviews from dissatisfied customers (because their device suddenly released its magic smoke and stopped working for no apparent reason) won't hurt the creator or manufacturer?

Fiber Optics In Antarctica Will Monitor Ice Sheet Melting

That's obviously false, as evidenced by the fact that the sun rises earlier when daylight saving time is in effect. If that isn't political will commanding nature, then what is?

The Future of Stamps

Ichijo Re:Pitney Bowes (131 comments)

What does this provide that a postage meter doesn't?

The ability to keep your mailing address when you move, similar to the way third party webmail services let you keep your e-mail address when you change ISPs, or the way VoIP services let you keep your phone number when you move, or the way DNS lets you keep your URLs the same when you change web hosts.

FTFA:

When Martin Cooper invented the cellphone at Motorola in 1971, his idea began with the simple insight that telephones were attached to places. They were rooted at a home or desk, for exampleâ"and it was simply by coincidence or mutual agreement that the right person was at that location when the call was placed. The cellphone was meant to make telephones about reaching people, not places.

Speed Cameras In Chicago Earn $50M Less Than Expected

Ichijo Re:But the speed camera folks are laughing .... (397 comments)

When turnpike operations are sold to such private companies, they have clauses preventing the improvement of alternative roads owned by the state or city that would divert traffic away from the turnpike.

Yes, it's very difficult to compete with someone who has such deep pockets as a government. This is one reason why infrastructure should be financed by its users in proportion to the benefit each person receives from it, instead of paying for infrastructure through unrelated taxes such as the sales tax.

An Algorithm to End the Lines for Ice at Burning Man

Then open two queues: one for people willing to pay the market price, and the other for people who want the old price. Since the ice is still available at the old price, nobody can complain of being ripped off.

An Algorithm to End the Lines for Ice at Burning Man

Ichijo Supply & demand (341 comments)

The existence of a queue means that people are willing to pay more for the product. So why not let them? Raise the price as the queue gets longer, and lower the price as the queue gets shorter. This stabilizes and even lets you control the length of the queue.

They should do the same at ballparks on game day. Instead of charging a fixed rate for parking, charge to go through the gate according to the number of cars waiting to get in or out. If you get there really early, you could get in practically for free, and if you tailgate after the game, you can get out practically for free. With shorter queues and a greater ability to save money, everybody wins!

As Prison Population Sinks, Jails Are a Steal

Ichijo Re:Prison population (407 comments)

e

Felonies are also ridiculously easy to get. In the '80s, if two people were caught racing in their cars, it would be a $111 fine. Now, here in Texas, that is a felony.

Rather than a prison sentence followed by automatic eligibility to be re-licensed to be a hazard on the streets again, I think a far more appropriate punishment would be to permanently revoke the person's license until he or she can prove, through a battery of physical and psychological tests, that he or she is no longer a hazard on the road. (This is what they do in Germany.)

But in the USA, for some reason it seems to be considered more humane to make someone a felon and lock them away than to ban them from driving.

Great for private prison profit margins... all paid for on the US taxpayers nickel.

This is why the goals of prisons need to be aligned better with the goals of society. Instead of putting someone away for x years, if private prisons bid against each other on a fixed price to rehabilitate each prisoner, coupled with penalties each time a released prisoner re-offends, private prisons would do their best to rehabilitate each prisoner as quickly, completely, and inexpensively as possible. Isn't this what we all really want?

Bill Gates: Piketty's Attack on Income Inequality Is Right

Ichijo Re:Let me get this right (838 comments)

no housing allowed in the industrial zone

That's a silly law. It should be the other way around: no industry allowed in the residential zone.

Would you like to explain how those zones "keep the poor and minorities out of middle-class and wealthy neighborhoods"?

When you force every house to have parking (which people too poor to own cars don't need), you drive up the cost of housing and drive out the poor from the neighborhood.

You also drive out the poor with limits on dwelling units per acre, minimum liveable square footage, and prohibitions against granny flats, dorms, and boarding houses.

Bill Gates: Piketty's Attack on Income Inequality Is Right

Ichijo Re:Let me get this right (838 comments)

No, it's the victims and the rest of society who seek revenge (called "retribution" by lawyer types) who create the need for imprisonment.

Because the main purpose of prisons is revenge and not rehabilitation, prisoners benefit very little from prisons. And because our society decided that people should pay for things in proportion to the benefit they receive from them, it stands to reason that prisoners should not pay for their own incarceration.

Bill Gates: Piketty's Attack on Income Inequality Is Right

Ichijo Re:Let me get this right (838 comments)

Middle and lower income households absorb the greatest percentage of social programs, so why shouldn't they be the ones that contribute the most to them?

That's like asking prisoners to pay for their imprisonment. Remember, the purpose of the zoning code is to keep the poor and minorities out of middle-class and wealthy neighborhoods, and that in turn restricts economic mobility, keeping the poor dependent on social programs for their livelihood. For example, the market would build more affordable housing if it weren't prevented from building it.

(Side note: this is similar to the way motorists support separated bicycling infrastructure, in order to get bicyclists out of their way. And then they complain that bicyclists aren't paying their fair share for those separated facilities.)

So I think the people who actually want those social programs (the wealthy) that keep the poor poor should be the ones to pay for them.

Wind Power Is Cheaper Than Coal, Leaked Report Shows

Ichijo Re:Article ignores variability (610 comments)

...when wind varies you need to have other types of power (such as natural gas) ready to pick up the slack.

You're half correct. If you'll recall your demand curve from Econ 101, when demand exceeds supply, there are two ways to reach an equilibrium. Your suggestion, increase supply, is one of those ways. The other, of course, is to reduce demand, as eBay does to prevent too many people from winning the same auction.

An X Prize for Algae Biofuel

Ichijo Ichijo writes  |  about 5 years ago

Ichijo (607641) writes "A $10 million Algae Fuel Prize has been announced by venture capital firm Prize Capital to encourage development of commercially viable fuel from algae. "The Algae Fuel Prize's rules specifies that the winner must produce 3,000 net gallons of diesel fuel per acre at a cost of no more than $3 per gallon. The net quantity is obtained by subtracting the gallons of fuel used in producing the algae from the yield. Prize Capital will also work to arrange buyers for the fuel.""

Simplifying U.S. Currency

Ichijo Ichijo writes  |  more than 10 years ago

Here is what the 2004 U.S. nickels will look like.

Personally, I think we should get rid of the penny and nickel, and drop a digit in currency calculations. As the price of the penny rises in proportion to the cost of making that penny, we're eventually going to have to do this anyway.

If the penny and nickel are gone, we would also need to get rid of the quarter for obvious reasons. And as long as we're messing with our pocket change, we may as well do all these changes at once:

  1. Remove the penny (cent coin). It costs a lot to make and people don't use them often. They can't be used in vending machines, we already have currency with Lincoln on it (the $5 bill), and a penny is worth only a fraction today compared to 1793 when it first came out.
  2. Remove the nickel. People are afraid businesses will cheat customers out of 2.5 cents of every transaction. It's a stupid, trivial issue, but the U.S. is a nation full of stupid, trivial people. (But not exclusively in any sense.)
  3. Replace the quarter with a Washington 20-cent piece.
  4. Remove the dollar bill. It's a pain to use a crumpled dollar bill in vending machines anyway, and we already have its replacement (the Sacagawea). The Sacagawea has so far failed to catch on because we still have the dollar bill, and because it takes time and money to replace vending machines, cash drawers, etc. (This is why we should make all the changes to our currency at once.) While we're at it, we might as well replace Sacagawea with MLKjr as per H.R. 1016, the " Dr. Martin Luther King, Jr., 1 Dollar Coin Act." MLK did more for the country than Sacagawea did anyway.
  5. Create a $2 coin with Jefferson, to replace the $2 bill with Jefferson.

So in the end we would have:

  • (coin) Roosevelt 10c
  • (coin) Washington 20c
  • (coin) Kennedy 50c
  • (coin) MLK $1
  • (coin) Jefferson $2
  • (bill) Lincoln $5
  • (bill) Hamilton $10
  • (bill) Jackson $20 (Is Jackson worthy of being on the currency anymore?)
  • (bill) Grant $50 (Ditto for Grant.)
  • (bill) Franklin $100

Notice the 1-2-5 trend? It's simpler than the irregular system we have in place now, and is similar to the Euro currency system (except without the 1 and 5 cent pieces).

Remote Desktop Software Reviewed

Ichijo Ichijo writes  |  more than 10 years ago

I wanted to be able to access my work computer from home. Sometimes I hit upon some inspiration and I want to test it out on the software. (Downloading the source code to my computer at home is not an option.) So I tried a few types of remote desktop software.

My work desktop is set to 1600x1200, but my computer at home can only do 1400x1050. So in addition to the slow network connection, this was the other problem I needed to deal with.

The first, UltraVNC (free), won't work for me at all since VNC is already installed on my work computer, and this both precludes me from adding a VNC account and from installing other VNC software. Apparently you can't have two copies running at the same time, even if they are different implementations. VNC was already installed for the benefit of the help desk.

Another one I tried was Remote Administrator 2.1 ($35). It worked surprisingly well over the slow network connection. Upping the pixel depth to its highest setting didn't seem to make a difference in speed. And while the resize mode sucked (no bilinear filtering), the autoscroll mode was usable (just like a virtual desktop in Windows). The fact that you had to use Ctrl-F12 to get to the menu was kind of annoying. Still, I hoped for something better.

Then I tried the most obvious solution, Symantec pcAnywhere 11.0 ($200 retail). I was able to get a copy off eBay for about $20. This one fully bilinear-filters the desktop when resizing, but like Windows Media Player and Quicktime, the "bezel" (actually an Outlook-style side menu) takes up space that cannot be reclaimed. Also, pcAnywhere seems to be very frugal on network traffic. Unfortunately, and this is the real deal kiler, pcAnywhere is slow! Refreshing a certain window takes four seconds in pcAnywhere, where it took 2.5 seconds under Remote Administrator. Changing to a different pixel depth didn't seem to make any difference. pcAnywhere is still usable, but only in emergencies, whereas Remote Administrator could be used pretty much all the time if you wanted to.

So if you're looking for remote desktop software, I recommend Remote Administrator.

The Problem with Microsoft Certification

Ichijo Ichijo writes  |  more than 10 years ago

Microsoft's certification exams serve one main purpose: to test a person's knowledge of Microsoft's technologies. As such, they are both too broad and too narrow.

They are overly broad in that you may use only a subset of these technologies in any one job. Each test has multiple areas of study, instead of having multiple certification tests, each on a specific subject. This has two side effects: any person taking the test must be somewhat familiar with more technologies than he or she may use in any one job, but at the same time it is not required to be thoroughly familiar with any of them. In fact, around 40% to 50% of the answers may be missed while still passing the exam. Is it important for an auto mechanic to have only a passing familiarity with both engines and body work, or is it better to specialize in the one or the other? Which of the three types would you hire to fix your engine? To repair a dent?

The tests are also too narrow for the purpose employers are using them: a "litmus test" of how "good" a programmer might be. A person can pass one of the Visual C++ exams without needing to understand C++ at all, much less be able to write readable, easily extensible, fast, stable, or bug-free (and bug-resistant) code. It doesn't test a person's ability to gather requirements or produce a good software design.

As a result of these shortcomings, many people think the tests are good for nothing. I would submit that the tests are good for one (and only one) thing: to test a person's knowledge of Microsoft's technologies (as stated above). In other words, they might be useful for a manager, not a programmer. They do not achieve the purpose many people think they do, to test how "good" a programmer might be. Unfortunately, while there are industry tests that cover the missing gaps, none of them seem to very popular. These include ICCP's ACP and CCP certification tracks, and IEEE's CSDP.

e*Trade vs. Firstrade

Ichijo Ichijo writes  |  about 11 years ago

Or, a crash course in online discount brokers.

This is a long one, so go get your hot chocolate (or other drink of choice) and get comfy.

I had some extra money and I decided last month to use it to invest in stocks. Up until then, my only exposure to the stock market had been my 401k and my company's stock purchase plan. Last month seemed ideal because good reports were coming in all around about the economy.

e*Trade

Because my stock purchase plan is through e*Trade's OptionsLink, and because their fees aren't bad ($12.95 per trade), I decided to use e*Trade as my broker, but because they have a $1,000 account funding minimum, I had to wait until I had that much extra lying around, which turned out to be last month (September, 2003). In order to avoid wire transfer fees, I mailed in a personal check. Five days later, the funds were available. This was, in my estimation, too slow by about two or three days. Dock one point from e*Trade.

My stock of choice was Intel. Long story short, I believe the stock is undervalued and it should double in two to three years. So I placed my order, but instead of $12.95 for the trade, they charged a total of $22.95! It turns out e*Trade charges $19.95 for NASDAQ stocks, and there's an extra hidden $3 fee. Before I can see a profit on a stock trade, the combined value of the shares has to rise above the cost of the transaction. Dock another point from e*Trade.

Firstrade

So with the long wait between mailing a check and the funds being deposited into my account, and with all the fees, I decided there had to be something better, especially for shorter term holdings. Doing a little online research, I found an article comparing the various online brokers. Using their table of ratings, I chose Firstrade, in part because of the lower transaction fees. Score one point for Firstrade.

As with e*Trade, I mailed a check. However, this time it took seven (7) days for the money to show up in my account. Oh well, big deal, a difference of two days. Dock half a point from Firstrade.

I placed my orders, and... they were rejected. All three of them. No explanation was given. Hmm, I thought, maybe a glitch. So I tried again the next day. Rejected. What good is a broker if they keep rejecting your orders? Dock one point from Firstrade for not giving a reason. Well, I thought, this was a good time to test their customer service (one reason I chose Firstrade in the first place). They replied the same day (score one for Firstrade) and stated that the reason my orders were rejected was because they were waiting for my check to clear, and it was going to take ten days. From the date they deposited my check.

Ten days! After waiting seven for them just to receive my check! Clearly, Firstrade wasn't going to be the short-term, diverse portfolio I was hoping for. Dock two big ugly points from Firstrade for being overly paranoid about their own clients. But it gets worse.

It Gets Worse

This time I chose AMD, General Dynamics, and Amazon ). With the lower fees, I felt I could diversify a little better than with e*Trade, for the same amount of money to invest. Between the time I originally tried to place my order and the time my check finally cleared and the trade finally went through, those three stocks had all risen in value by an average of 10.6% each! (AMD alone was up 20%.) I guess I'm really good at picking stocks but really bad at picking brokers. Anyway, to try to get a better deal, I placed limit orders (don't trade until the stock goes back down below $x) on all three stocks. Expensive mistake, because it turns out Firstrade charges an extra $5 for a limit order. (This was my own fault for not reading the fee schedule, so no points taken.) And because I had already calculated my trades pretty close to my account limit, the extra fees caused my account to be $10 overdrawn after the trades.

Now that didn't make sense. My trades wouldn't go through earlier because my funds hadn't cleared and therefore I effectively didn't have any money in my account, but they went through now despite not having enough in my account. Dock a half point from Firstrade for stupidity.

Conclusion

Read the fine print! Get a list of fees, and find out how personal checks are handled. As it stands, I'm not sure which of the two will be my main broker. In the end, it's been an educational, if not expensive, experience.

Final Score

e*Trade: -2
Firstrade: -2

Update (Thursday October 16, @01:33PM): At this moment, about a week after that ill-fated trade, my Firstrade stocks have risen enough to start showing an overall profit on the three transactions. Thanks to all who expressed their sympathies.

Update (Wednesday November 19, @2:43PM): Two other intriguing brokers are Freetrade (free, but with some important footnotes to read first) and ShareBuilder (an inexpensive investing program similar to a 401k).

Worse is better (or is it?)

Ichijo Ichijo writes  |  more than 11 years ago

The subject of this journal entry is the argument of "worse is better" vs. "the right thing." An article about the subject written by Richard P. Gabriel who coined the former term can be found here.

The "right thing" philosophy of software design, also known as the MIT/Stanford style, emphasizes simplicity of interface, absolute correctness, complete consistency, and as much completeness as possible.

In contrast, the "worse is better" philosophy emphasizes simplicity of implementation, and allows the other ideals to be compromised slightly in order to achieve this.

As the article goes on, there are many arguments for and against each design philosophy. Who can say which is really better?

I'm a "right thing" sort of person. I want to be able to quickly get a mental picture of what's going on in the software at a glance. I want to be able to easily pick up where someone left off.

On the other hand, I don't like it when low-level information is hidden from me. It is easier to show low-level information in "worse is better" implementations than those in "right thing" implementations, but this doesn't mean it can't be done. For example, if packets are colliding on my local network, I like to see the little red LED light up on the switch, but I don't want scrolling logs filling up my screen. When I'm burning a CD, I like to see the bar graph indicating how much is done another indicating how full the CDR's buffer is without seeing something like "x of y blocks transferred". I believe there's always a way to show low-level information on a "right thing" implementation. It's just that sometimes it takes some extra design work to come up with the answer.

The traditional UNIX style is "worse is better." MacOS (including OSX) and BeOS are "the right thing." Windows doesn't seem to be polarized to one end or the other.

Most of the programmers on my team are a "worse is better" lot. I'm a "right thing" person myself. I'm growing increasingly intolerant of (what I perceive to be) bad code.

The whole philosophy doesn't apply only to programming. It applies to the design of everyday things. Do you prefer a stick (worse is better) or automatic transmission (right thing)? A VCR (worse is better) or a TiVo (right thing)?

What style of person are you?

Full Circle on the Internet

Ichijo Ichijo writes  |  more than 11 years ago

Or, The Right Thing vs. Worse Is Better.

Has this ever happened to you? You go searching around for something, and it brings you back to something (almost) completely unrelated that you've seen/done/met before.

I've been having trouble setting up Qmail under FreeBSD. I and zoarre want to replace Sendmail on our server with a better, more secure mail server. Qmail's supposed to be the best.

Installing Qmail isn't as simple as installing a package, because Qmail's license doesn't allow distribution in binary form. And it also isn't as simple as compiling the port.

There's an alternative: Postfix. It was also written by a security type, and while it doesn't guarantee security, it's able to hold its own against Qmail. So today I was searching around for comparisons between Postfix and Qmail, in particular user experiences. So typing this into Google:

I came across an interesting article titled "Sendmail." More interestingly, it made reference to a book titled "The Unix Hater's Handbook." Apparently it's out of print, and the used copies offered by Amazon Marketplace sellers are priced at $99 for the one copy or over $300 for two other copies.

So back to Google again to see if anyone else had a copy. (eBay would have been my next choice.) Apparently, there are some free .pdf copies floating around the Internet, one of which is linked from an article titled "Unix History." The same article talks about the Jargon File, which I also like, so I took a closer look. At the top of the page is a link to an article titled "Worse is Better."

Without going into its contents (I'm saving this for another journal entry), let me just say that the article mentions a "young kid from Pittsburg named Jamie Zawinski" (initials JWZ). Is this the same JWZ of the weblog jwzrants? (I have that weblog bookmarked.) Indeed it was, and we've come full circle.

This also happened a couple of weeks ago. I was reading another weblog which linked to something which mentioned a Phil Windley. It took a minute to remember where I had read that name before. He's the sysop (okay, webmaster) of the Japan Tokyo South Mission alumni page (I served my mission there).

In the words of Johnny Carson, that's some "weird, wild stuff."

The Seven Sins of Deadly Meetings

Ichijo Ichijo writes  |  more than 11 years ago

Here's an old article (but I just found it) about holding effective meetings:

I thought the article was interesting because the author seems to advocate the use of technology in meetings to help make them more productive and encourage more ideas and other feedback. Also, a lot of his points hit home because my own team has problems holding effective meetings.

The following are my own notes from a CBT training course about holding effective meetings:

The 5 P's of Preparing a Meeting
(These should be part of the meeting request.)

  1. Establish a Purpose
    • "What do we want at the end of this meeting that we don't have now?"
  2. Manage People
    • Leading - managing the content/information
    • Facilitating - moving the meeting through the agenda items, managing the people
    • Recording - recording the key points of the meeting, producing the minutes after the meeting
  3. List Prerequisites
    • What to do before the meeting?
    • What to bring with you to the meeting?
  4. Organize Practicalities
    • Length of the meeting
    • Time of the meeting
    • Gather equipment, remove distractions
  5. Create Points (Agenda Items)
    • Inform (what, how, whom, how long)
    • Discuss (...)
    • Decide (...)
    • Act (...)

OPEN Technique of opening a meeting

  1. Orientate everyone
  2. Present the purpose
  3. Establish the agenda items
  4. Nominate roles and rules

CLOSE Technique of closing a meeting

  1. Call a halt
  2. List the outcomes
  3. Obtain commitment for assignments
  4. Set up the next meeting
  5. Express appreciation

Moore's Law of Computer Science Degrees

Ichijo Ichijo writes  |  more than 11 years ago

So our CS Ph.D guy wrote a class to chop up a string by a given token character. It uses strtok() which is not thread-safe, so he wrote this disclaimer:

// if object is used by only one thread then it is thread safe

This kind of description from a Ph.D truly boggles the mind.

Now keep in mind the following terms:

class-level thread safety: Objects of the same class may safely be instantiated any number of times in the same or multiple threads. This means there is no global data (with the possible exception of instance counters). However, multiple threads may not necessarily be able to safely access the same object.

object-level thread safety: A single object of the class may be safely accessed by multiple threads. A class that is safe on the object level offers synchronization for its data members.

So his code was thread-safe on the class level but not the object level. But we're just getting started...

So far he has only used this routine in a situation where we already have a completely (class & object) thread-safe string-chopper. Now the string in question represents a data structure, so you should not parse it yourself. Anyway, I've always thought, if you're going to reinvent the wheel, you should make a better wheel.

I've identified two main problems with his code so far (it's redundant and not thread-safe). But this is the same person who:

  • replaced a database with a series of ASCII (not Unicode) flatfiles with non-escaped field delimiters, which depends on the Windows registry for some of its data, and
  • thinks, because we use structured exception handling to catch OS errors, he doesn't have to fix his NULL pointers. This leads us to the fact that he...
  • always uses char *'s instead of C++ strings.

I hope he doesn't use that strtok class for creating and parsing CSV files, because I'm afraid he won't use proper escapement.

We also had an employee from India with a Bachelor's degree in Computer Science. He and an ex-lawyer were the only two programmers we've ever fired due to technical ineptitude.

Speaking of degrees, have they even started teaching C++ and OO in college yet? Chances are you won't learn about realtime operating systems, Beowulf clusters, Extreme Programming, or any other cutting-edge technology throughout your Computer Science college career, unless you do your own research.

So all of this background brings me to my point. Just as a brand-new computer is obsolete before you bring it home, so are Computer Science degrees. Call it Moore's Law of Computer Science Degrees. Maybe mandatory refresher courses to maintain your degreed status and/or industry licensing/certification are the answer.

Update (6/8/2003): I should point out that my good friend Zoarre disagrees with my conclusion. The principles learned on the road to a CS degree will withstand the test of time and can make a programmer better. (The example I gave of the Ph.D he dismissed as being a "sloppy coder.") In his words:

A CS degree can only help a good programmer write better code. If someone with a CS degree (or a PhD) is a shitty programmer, it's because they always were.

Zoarre doesn't have a degree, but he's worked with both types of programmers. I don't have as much experience as he does, but I think he's right. So I stand corrected.

Ichijo Ichijo writes  |  more than 11 years ago

The new AmigaOne motherboards ship with SuSE Linux PPC, because the new Amiga OS has not yet been released.

Now SuSE on an AmigaOne motherboard in itself isn't a good reason to spend all that money. But take a look at this: [screenshot]

Yes, it's Mac OS 9 running under Linux via Mac-on-Linux. OS X should also work in this configuration. Mac-on-Linux uses the processor directly without any emulation, so it should be pretty speedy.

When Amiga OS 4.0 comes out, you'll essentially be able to run three different operating systems on the same computer.

Zinzala for QNX

Ichijo Ichijo writes  |  more than 11 years ago Found this over at OSNews. Zinzala is an object-oriented Photon-based SDK that is fully scriptable. It appears to be both powerful and easy to use.

Inheritance Abuse

Ichijo Ichijo writes  |  more than 11 years ago

Ran across an interesting use of C++ class inheritance. In a friend's a LED-style window class, he has a dynamic array of "states" that the user of his class can populate. A state consists of a numeric identifier and a color.

So, it sounds simple. Create a structure called "state," set the members "id" and "color," and add it to the array.

But this isn't the way it was done. Instead, I (the class user) am required to inherit from the abstract class "state" and overload a virtual function to set the color. So for every different color, I have to create an entirely new class. Does this make sense?

Besides being complex and wordy (extra typing for the class user), this method has the following disadvantages:

  1. Each instance of the class adds memory for each of the member functions.
  2. There's additional overhead in calling member functions vs. retrieving data members.

I'm completely baffled. One of the only explanations I can come up with is that some people feel complex, verbose code is good code.

My other theory is that people code the way they talk. I prefer to make my comments brief and to the point. My friend takes the opposite approach, using long explanations and examples to support whatever his position is, long after he's made his point. Would this explain his coding style? Or am I just ignorant? (I'm prepared to accept both answers.)
