random neuron misfires

At the recommendation of a close friend who knows I’m a gadget black hole, I went out and bought a D-Link DSM-G600 wireless NAS enclosure.

This device seemed to be the perfect replacement for my Ministack v2 enclosures (I have 4 of these). The D-Link was an enclosure that had seemingly fixed the flaws I found in my Ministack units. Larger fan, more space around the drive, 2 USB 2.0 ports, an onboard webserver, ftp server, email alerts, GigE, and.. wireless!

My hopes were soon crushed, once I started poking at the actual enclosure. Sigh.

The enclosure does indeed have a lot of room in it, which helps with the cooling. The internal cabling left quite a bit to be desired, especially the flat ribbon cable. I had to bend it at a weird angle to fiit it across the top of the drive.

Now, on to the major quirks:

1. Whatever drive you put in it, regardless of whether or not the drive has data on it, must immediately be formatted to ext3. Yes, that’s right.. you can’t put a drive with data in this enclosure, if you intend on keeping the data on the drive.
2. No filesystems supported except ext3. This means no support for extended journal options (such as data=ordered) and no other filesystems supported. No XFS, no JFS, no FAT/FAT32, no NTFS… nothing except ext3. If you format your drive to another filesystem and put it back into this enclosure, you will be forced to format it as ext3 again anyway.
3. Broken networking. D-Link saw to it that the IP that you assign in the static IP section of the setup.. is the same physical IP that is used for both LAN and WAN ports. How nice. This also means that every other packet sent to the device, is a “DUP!” packet. It might explain the horrible performance of the device when sending data.
4. No web interface over wireless. Once you configure the device and enable wireless, you can no longer tweak or reconfigure the device over wireless. You MUST use the LAN connection to configure the device once wireless is turned on.

There are at least two separate security issues affecting the GoAhead-Webs webserver that powers this interface. I didn’t have time to validate these myself, since I’m not keeping the device, but I’ll bet others who have these devices will be vulnerable to them. Ugh.

After about 5 hard resets to get it to properly finish formatting the drive, and then trying to configure the crazy, misconfigured networking options with their web interface, I was ready to map the drive through Windows and then with Linux, using ‘mount -t smbfs’ and the standard options.

On to the second major problem: the speed. This thing is SOOOO slow when sending data to it. Reading data seemed to be fine, but writing data to it was, at best, 180k/sec.

The web interface is among the ugliest I’ve ever seen. With 30 minutes of work, it could be really amazing, including adding in some majikal AJAX fu. That’s not really important, but the interface is completely disorganized. Options that should be grouped together, aren’t. Sub-options that should be in separate places, aren’t.

Apparently Rev A of this enclosure is XScale-based, larger RAM, larger flash capacity, Atheros wireless, and some other things. The Rev B (which is the only one BestBuy sells, unfortunately) is PowerPC-based, less ram, less flash, and not very hackable.

There is a group of people who are interested in hacking on this box on the OpenWRT forums, but they’re focusing their efforts on the Rev A. model, not the Rev B. which I happened to have. D-Link has posted the sources to the GPL versions used in the box, but I don’t have my toolchain set up, so I can’t go building a custom firmware for it. Another long thread on this box is over here, and it seems like people want it to do fun things, but the development seems stalled/dead.

Here’s the list of things I’d suggest D-Link focus their efforts on, to make this device work properly:

1. Fix the broken networking configuration. You should never bind the same IP to two physically separate interfaces, ever!
2. Clean up that web interface, its a mess. Group logical options together, and make it flow cleanly.
3. Optimize the Samba config, and use the latest release of Samba. The default config used on this device is CLEARLY affecting the horrible write speed of the device. I have several Samba servers running on Linux and FreeBSD here, and I regularly get 2-3M/sec. transfers over wireless to these machines. Whatever D-Link is doing, is less than 5% of that speed.
4. Update that kernel to 2.6. and add some optimized kernel options at boot time (scheduler=deadline, panic=30, etc.)
5. Work on a better internal cabling system. Look at the Ministack v2 internal cabling for a perfect example of how to do right-angle bends with an IDE signal cable.
6. Make the front power-on button into a proper power-off button as well. It turns the device on, but the only way to turn it off, is to unplug it. Not smart. Its not even ATX compliant, so holding the button down for 7+ seconds doesn’t reset it or power it off either.
Overall, I’d give this 2 stars out of 5, if I had a rating system. Its going back to BestBuy for a credit. Its another “Not Quite There Yet” device, but it has the potential to be.. with a bit more hacking.

I was pointed to a blog entry called “How NOT to Lead Geeks“, and I found several items very interesting and eerily familiar:

The main reason IT people are unhappy at work is bad relations with management, often because geeks and managers have fundamentally different personalities, professional backgrounds and ambitions.

In my IT career, I’ve almost always played the role of Geek+Manager, or Manager+Geek, depending on which part consumes the larger percent of my time. I’ve played on both sides of this table, locking horns with Management about the wrong way to lead their technical staff, as well as trying to “herd cats” as a Technical-Manager-of-Geeks.

In my OSS world, I also have to lead and manage and guide geeks, many of which I will only ever know through email. Not knowing your team personally has a distinct impact on your ability to build trust and confidence. The rules change quite a bit.

I recommend every Manager work with a team of people he will never meet in person, and hone his skills there, to be a truly successful manager with the team of people he does work with in-person.

Here’s the Top 10 from “How NOT to Lead Geeks“:

1. Downplay training
2. Give no recognition
3. Plan too much overtime
4. Use management-speak
5. Try to be smarter than the geeks
6. Act inconsistent
7. Ignore the geeks
8. Make decisions without consulting them
9. Don’t give them tools
10. Forget that geeks are creative workers

Of these, #2 and #9 are the ones where 99.999% of all “Managers” fail. Almost every manager fails here because they believe they are there to “manage” people, “tell” their staff what to do, and they expect those things to get done.

WRONG!

A manager has one job description: Give his team all of the tools necessary to do their jobs (i.e. meet their goals, as agreed to by the entire team), and then step out of the way.

When political pressure threatens to affect the progress of that team (geeks or otherwise), the “manager” is expected to step in the way and deflect it. At no point should a team have to deal with anything political to get their jobs done.

These tools can be physical tools (applications, access to systems), communications tools (introductions to the right edge teams to minimize overlap), or social tools (meet-n-greet with other members, build camaraderie, offsites to let off steam, training..).

Many managers believe their “subordinates” (they already building walls by using that term) are supposed to do “what they are told”, and not complain or cause waves. It ends up building a situation based on office posturing and finger-pointing when things slip or don’t get done on time. To cover the situation, good people get fired or laid off. When you see this happening, it is always because of bad management, not bad technical people.

Rarely do you see the Geeks survive the pink-slipping, while managers get to keep their jobs… the same jobs they’re doing poorly time and time again.

If your technical team is performing poorly, you need to look at a few key items. All of these items point back to the competence of the manager, not the team itself:

1. Did you hire the right people with appropriate skills to achieve success? You were responsible for hiring and selecting the team. If they lack the skills, you chose poorly.
2. Do they have all of the tools and training necessary to do the jobs being asked of them? Did you provide access to the right systems, people, training for your team to grow and complete their goals?
3. Are the deadlines and goals realistic? Is everyone in agreement with the goals? Did you consult with the team to find out what their opinion was? Did you listen to their opinions and comments objectively?
4. Are you (the manager) in the right place in the team? Not too close to smother or micro-manage the team, and not so far away that you lose sight of the progress on goals.

Another good point in this blog was:

Geeks usually know the technical side of the business better than the manager, so making a technical decision without consulting them is the biggest mistake a leader can make.

I have seen one major company implode based solely on this exact problem. We went from 250 people down to less than 30 people in 2 years, and rotated through 4 CEOs and 5 rounds of layoffs in that time. Hundreds of amazingly-qualified, brilliant technical people were laid off in wave after wave. Why? Because they were never asked if what the company was doing, was the right thing to do.

The “Managers” (and I use that term loosely here) at this company were agreeing to do work for clients that was simply impossible to do, under even more impossible deadlines. If the geeks were consulted, the projects would have been realistic, on-time, and completed to profit. That never happened, so who had to go? Not the manager of course… The geeks. Very sad to see hundreds of talented colleagues laid off time and time again.

In my experience managing and being managed by dozens of managers in my IT career as I moved up and around the corporate landscape, I have only had 1 manager that did exactly this, and in 2 years, everyone under this manager received a promotion every year, because of the rapid success and accomplishments. I was on my way to my third promotion in just as many years, when I decided to resign and work for the company above, that fell on its face.

But I strive to be exactly the style of manager that I had when I was at my best. High-volume, low-stress, clearcut and productive with every task and project.

I should also add that I’ve never been fired or laid off from any job I’ve had, both as Geek or Manager, and I don’t intend to. I make my points heard, even if it means risking my job. In every case, my voice has either saved the team, project or company with realistic objectives.

I saw this comment on Slashdot today, and I had to re-post it here, because it really captures exactly what I’ve been thinking for the last two decades or so, watching this mess go by in our society and administration and environment:

Rights are not granted to us by the government.
We grant rights to the government.

Any attempt to reverse this will, in effect, start a bloodbath that I would be happy to participate in to preserve what is rightfully ours. Even if some of those rights are things I do not agree with. They are ours and ours alone.

The government is merely a keeper for its citizens, soon to be or otherwise protected by natural inalienable human rights and its sole obligation is for our collective protection and benefit for the long and short term.

Amen my Slashdot brother, amen.

UPDATE: I’ve been hearing dozens and dozens of comments and corrections from this one entry, one in particular which clarified that we grant “limited powers” to the government, not “rights”.

Seems quite a few people take this issue very seriously. Keep the comments and inertia going, everyone.

After watching most of the episodes of American Inventor on ABC, and having my wife tell me several times that I should have been on that show, I’ve found myself pondering the reality of that.

I’ve easily “invented” hundreds of things over the years in my life to make life easier, solve silly engineering problems in other products, and in general just “fixed that which is broken” by coming up with a better solution.

But are these “good ideas” or are they “inventions”. Wikipedia defines invention as:

“…an object, process, or technique which displays an element of novelty. An invention may sometimes be based on earlier breakthroughs, collaborations or ideas, and the process of invention requires at least the awareness that an existing concept or method can be modified or transformed into a new invention…“

Can I be an inventor? Are the things I’ve “invented” to solve problems in my life and the lives of others really “inventions”? Are they “good ideas”? Sure, they’re both. I’ve come up with many things that eventually came out on the market on their own, years before they were released. Could I have captured the market and made some money on these inventions? Absolutely. (Of course, I firmly object to patents, but that’s another matter entirely =)

Last night, Janusz Liberkowski won the first American Inventor award with his “spherical safety seat“, a means to safe the lives of infants involved in automobile accidents. Doug Hall was his mentor on this task, and throughout the competition, it seemed clear that he had the most novel of all of the inventions there.

I really did think Francisco Patino was going to take the win last night, based purely on the potential market dollars for his invention. The bicycle market is a $2B industry, its massive. He received the lowest number of votes. I found that surprising.

I also thought that Ed Hall’s WordAce game was a great invention. It too had a large market. When you look at these three inventions, WordAce really has the biggest amount of potential penetration. Kids of all genders, races and ages can use it, even those who are too old for a car seat or those who can’t even ride a bike (handicapped?). Adults could use it, schools could use it as a learning and teaching aid. It had extrmely broad appeal. Add some additional functionality like “language modules”, “learning packs” and such and you could really extend it far. Make it networked, and play with users remotely across the Internet. Lots of potential for this kind of product. He’ll have to come up with a new name though, because “WordAce” is used in quite a few places that I can find, and is most-certainly trademarked by someone.

But Janusz’s invention, though extremely limited in scope and market, seemed to be the winner for everyone who called in and voted. Was it his empathetic appeal to everyone else that won the calling audience over? Was it the invention itself? Was it his commercial? I don’t know, but he did win… and its only fair to congratulate him on his invention.

Are these entrepeneurs? I’d argue that out of all of them, Francisco showed the most entrepeneurial spirit and heart, determination, and drive.

Now things are going to get really interesting… time to plan for my own appearance on American Inventor for next season.

Look Ma, no privacy!. It looks like the public is slowly being groomed to accept more and more invasion of their privacy at an even greater scale than before. London is piloting a program that will allow their public to sit at home, watching television, to tune into the more than 400 closed circuit cameras around town, 24×7, to watch their citizens for crime.

What does this REALLY do?

Well, for one.. it makes it easier to anonymously report your neighbors for their crimes (remember ThoughtCrime?), and it also makes it MUCH easier for predators, pedophiles and other miscreants to zoom in on their prey, watch their habits, monitor their behaviors, and stalk them.

Nice.

Combine this with Apple’s All-Seeing Monitor, and you have a full 360-° solution to watching the people, and watching the watchers. Record all of this data (storage is cheap these days), and begin putting together profiles of everyone’s behaviors, by keeping them in their homes during great television shows, keep them outside during work hours, and so on.

Hey, this could all be a great experiment on how to control the human conscious, by filling it with all kinds of subconscious bombardment. At the same time, we slowly erode their civil liberties, burn the Constitution off in the corner, and begin to turn our world into a complete totalitarian state.

Here’s a note to the current administration thinking this is somehow a good idea:

George Orwell’s book 1984 was meant to be a warning, not a script! - David A. Desrosiers, 2005

This reminds me of David Brin’s “Transparent Society” (on amazon here), a non-fiction work wherein he forecasts the erosion of privacy, as it is overtaken by low-cost surveillance, communication and database technology.

Brin argues that true privacy will be lost in the “transparent society”; however, we have the choice between one that offers the illusion of privacy by restricting the power of surveillance to authorities, or one that destroys that illusion by offering everyone access (including the ability to watch the watchers).

There’s another great article in the Arizona Republic online edition, that describes all of the various ways in which our privacy is being eroded every day. Here are some of those examples:

• Cameras eye you while you drive, bank, shop, eat and sometimes even when you stray into your neighbor’s yard.
• Your boss could be monitoring your computer-usage habits, maybe reading your private e-mails. Even the bathroom may not be safe from snoopers.
• Stores keep track of your shopping habits, sometimes sharing the fact that you prefer Crest over Colgate with marketers.
• Applying for a mortgage lays open the full details of your financial, employment and residential history.

This quote really stands out in this piece:

“Former Phoenix Police Chief Harold Hurtt, who now heads the Houston Police Department, suggested recently that crime-fighting in Houston could be enhanced with surveillance cameras in apartment complexes, on downtown streets and in private homes.”

“I know a lot of people are concerned about ‘Big Brother,’ ” Hurtt told reporters at a briefing in Houston, “but my response to that is if you are not doing anything wrong, why should you worry about it?”

Perhaps Harold, because it violates the Constitution? Read your 4th Amendment recently? Just because you think you CAN stick cameras in every corner, doesn’t mean you’re legally allowed to.

And for that matter, why not just stick my own cameras on my own house, pointed in every corner of the street, driveway, street corners, and put those videos online for others to see. Its all public information, right?

These people seriously need a wake-up call.
