DevOps and the Invisibility of Success

Some of you may have heard that some new guy owns Twitter now. You may also have heard that despite the dire hand-wringing by <insert people you don’t like>, Twitter is still running. Therefore, you might be tempted to conclude, all those engineers weren’t really necessary in the first place.

There are a lot of people working around us right now whose job it is to keep bad things from happening. I worked in a very small tech company once, and the boss was constantly trying to reduce the hours of our only IT person because clearly things were running just fine. When the people are doing really well at keeping bad things from happening, we forget we need them at all.

Twitter manages gazillions of data, and they propagate that information around the world in near-realtime. So many ones, so many zeroes. And right now, all those tweets are still flying around, and we’re willing to believe for a moment that Elon Musk is not simply an idiot baby of blood emeralds, but some kind of business smart guy. Twitter is still running! But that’s a tribute to the hard-working people who don’t work there anymore.

Elon has seen things running smoothly, and has not stopped to credit the people who are responsible for that. Quite the opposite, in fact; he has sent them packing. The plane is autopilot; it is a credit to the people who built the plane that it may go quite a while before slamming into a mountainside.

Hot Times in the City

The temperature went over one hundred degrees here today, as it does sometimes (more often lately, but we all know that). At about 2pm the guys who messed up our ducts came back and fixed out ducts, and life was good — the best cooling this house has ever known. Until about 4pm. That’s when the AC shut down entirely. Hopefully it’s just a matter of replacing (again) the ridiculously huge fuses on the unit. (Although huge fuses mean huge power and BLOWING huge fuses means maybe it’s time to replace the damn thing.)

It’s warm in here right now. Warm enough that my laptop, already prone to run hotter than one would think necessary, essentially shut itself down to prevent it from burning itself up.

My laptop is a MacBook, and they are not generally considered good gaming machines for two reasons: one, the hottest games don’t run on Macs, and two, because Macs aren’t built to dissipate the heat that comes with the massive processing in a modern computer game.

But today I wasn’t running any graphic-intensive game. I did play NetHack for a while, but that is the opposite of graphics-intensive. And because I was playing on NAO, even that processing was happening in a data center somewhere (or perhaps, a linux box under someone’s desk).

MacBooks, when overheating, use a process to simply block out all other programs part of the time, to reduce the load so the computer can cool down. I reached a point today where the safety program was taking up all the time.

I quit any program that was even using the slightest CPU and the situation did not improve. I shut down the machine, waited a few minutes, and started it back up to the slowest reboot since DOS was on floppies, because the kernel task went straight to maximum protection.

Finally, I went to the freezer and pulled out a cold pack I use on my knee. I put the computer to sleep, and set the thing right onto the cold pack, and when I woke it up the machine was happy. For a little while, at least.

I have now used a second cold pack, which is why I’m able to write this right now.

If you search for “Refrigerated Laptop Cooling Pad” or any of a hundred permutations, you will get lots of hits, but none of them are actually refrigerated. They just have lots of fans. And while I’m sure that helps, I’m a little surprised that there’s no active cooling. The top-tier game machines have liquid cooling built directly into the enclosure. It doesn’t seem a stretch to extend the heat sink of a metal-hulled laptop with a refrigerated system to take the heat away.

I’m filing this episode under Get Poor Quick because this is such a golden opportunity for the right person. Get on that, right person! Make the Chill Spot. I’m tired of my laptop shutting itself down!

Pod Life

It was in late 2001 or early 2002. I was on an airplane, and I pulled 1000 songs out of my pocket, was navigating to find the album I wanted, when a man in the row behind me leaned forward and asked through the gap between seats, “What is that thing?”

It was an iPod. Until its release, there had never been anything like it. The mechanical click-wheel of those early versions was just so satisfying and intuitive, navigating through a large collection of songs was simple, even with the tiny black-and-white screen. “It passes the blonde test,” a blonde friend of mine said after a few seconds with the device.

Part of the iPod of course was timing. Suddenly it was possible to fit a hard drive (yes, an actual spinning-disk drive) and a battery into a little case with enough storage to play music. But on top of that was the design. Anybody could make a music player, but only Apple could have made the iPod.

And only the iPod could save Apple. There was a huge battle inside Apple over whether the iPod would work with Windows computers. Steve Jobs was absolutely against it. Steve got his way most of the time, but in this case ultimately other voices carried the day, and while Steve was not the least bit gracious in conceding, he was later able to recognize that decision as a turning point for the company. It was the moment the gadgets were allowed to grow independently of Macs, and eventually the gadgets became the center of the Apple ecosystem. And here we are now.

Today (or, recently at least, I don’t pay close attention) Apple announced that they will not be making any more iPods. It’s just as well; the iPod is now just an iPhone without the phone. The iPod nano was probably the pinnacle of the “thing that plays music” Apple offerings, although it was not as viscerally satisfying to use as its clunky ancestors. I have one of those around here somewhere as well.

The only surprise I felt at the announcement was that the company I work for was still making iPods up until now. It seems like once the pod had to play video it wasn’t really an iPod anymore (says this grumpy old man).

But… the headphones I wear could fit a click wheel. A million songs in your ear. Anyone want to make that real?

That Reply I got From Aptera

Posted on by
Reply

If you follow this blog you might recall a while back I wrote about a car company called Aptera. I got super-excited about the product, tried to ask more questions, and hit a brick wall. The wall wasn’t so much about the company hiding things, as it was about the people fielding the questions not being trained on how to refer them to the people with the answers.

I ended that episode, and the following updates, promising that if I heard from Aptera again, I would let you know. Then I did hear from them, and I didn’t let you know. Not cool on me.

In fact I later got a very nice letter back, that specifically addressed my core questions. Well, maybe not fully answering, but framing expectations. I have to say, the use of exclamation points really helped to sell me. They’re excited!

I’m going to put the whole message below. I expect I’ll fail to match the well-formatted text I received. Just the look of the message indicates that some care was put into creating it. You will have to take my word for it.

Does this restore my faith in the venture? To be honest, it does, at least a little bit. My desire for an outfit like this to succeed has almost nothing to do with my own transport, and everything to do with making cities in the western United States less carbon-awful.

Anyway, here’s the full reply that I promised before.

Hi Jerry,
I sincerely apologize that they were not able to get your questions answered! We are more than happy to assist. To give you some clarity into the situation, we are required to use a third-party platform/company to accept investors’ funds and work with the SEC to ensure compliance. This is not directly managed in any way by Aptera. So when you email [email protected], it does not go to anyone on the Aptera team, it goes to an outsourced support team that specializes in financial inquiries related to the investing process.
Please find answers to your questions below: 

  • Strangely, the Gamma body was due in Q3, and supply chain sorting-out for Q3 and Q4. /  Gamma production in Q4.

We had aspired to make a production-intent vehicle by the end of this year. We think we’re pushing that into next year, but hopefully not too far into next year. We’ve signed some significant agreements that we think will provide us parts in 2022 at a greater scale than we were anticipating before. So we think once we pull the trigger on manufacturing, we will be able to scale rapidly, and really start to crank out vehicles. But getting to that start of production is later than what we had expected at least a year or two ago. In addition, we do not have any plans to change pricing at this time. 

• Have the “Betas vehicles” been built?

The Beta builds are underway! We have a new 80,000 sq. foot assembly facility which is complemented by two additional spaces nearby for beta development, R&D, and solar composite manufacturing. We look forward to sharing our progress with you as we continue this phase of testing and development. Please stay tuned for video updates on our social channels such as YouTube. Betas are in progress! Here is our November update:  https://www.youtube.com/watch?v=GK-aamqGZS4.

• How is test validation going?

We look forward to sharing this with you over the next several months as we make more progress in the beta stage! We recently stepped into this phase and as progress is made we will provide updates directly from our CEOs Chris Anthony and Steve Fambro. We’re looking forward to announcing more information to our supporters. We are having all the betas being completed for the development vehicles to send to suppliers and validate production parts. The path to production did not happen as quickly as we had originally anticipated, but nevertheless, we are making great progress and cannot wait to launch. 

Please let us know if you have any questions. We are more than happy to assist. We are committed to moving mobility in a direction of sustainability and innovation. We cannot thank you enough for your support.  

The message was signed “Aptera Team”, and had a bunch of links to various social media.

At this point, with this message that really had very little of substance, I’m all excited again. Maybe this actually can be the car that breaks oil. Maybe this is the car that an inner-city grandma can afford to operate, and not have to worry about gas prices. It could be a game-changer.

Maybe it won’t be, but tonight at least, with all the things and whatnot gong on, I’d like to see this as part of a carbon exit strategy.

Apple’s Little Monster

Posted on by

I used to post about techno-gear fairly frequently, but I’ve tailed off, largely because since I began to work at Apple it would be easy to accuse me of homerism.

Today, as I was preparing to leave work, I got a message from the Official Sweetie of Muddled Ramblings and Half-Baked Ideas, asking for a friend about the Mac Studio Cube. That was how I learned about the new hardware my company announced today. Maybe I should have watched that presentation. At any rate, do not waste your time coming to me for any inside information.

The word “cube” immediately conjured images of the original Mac Cube, one of which sits, in its metal-wrapped-in-polycarbonate elegance on a shelf in the Muddled HQ compound.

The new Cube not as pretty, even if it is more recycled (100% of rare earth metals are recycled), but that’s not what got my attention. This little computer is a fuckin’ beast.

Not that long ago, Apple bailed on Intel and started making their own chips. The first generation of the M1 processor was a ground-breaker. Fast and incredibly power-efficient. The reason turns out to be pretty simple: a lot of power and speed is lost to the places the disparate chips in your computer talk to each other. The answer: put everything on one chip. Processor cores, memory, GPU, I/O, and all the rest. The result is much faster computers that use a lot less power.

Apple has rapidly expanded the line of processors—literally. The name “M1 Max” is not just an empty marketing name, the chip is literally the biggest single chip that can be made in quantity with current technology. To extend this idea any further, you either have to improve the silicon die technology to make bigger chips (which obviously everyone is doing), or you have to incur the cost of having separate chips talking to each other.

But what if you built your chip so that you should just sorta… glue it to another one? Today we heard about the M1 Ultra, a gigantic chip that is literally two times maximum. And the connection between the chips is so efficient that the scaling is almost linear.

It has been a long time since I followed the chip-fabrication press; back around 1986 they were still talking about optical computing (using lasers for logic gates to get to extremely high clock rates), and gallium arsenide was still the next big thing. Remember gallium arsenide? Of course you don’t. It was not the next big thing.

Which means while I have an interest in this stuff, I have no idea whatsoever whether anyone at Intel or AMD did a spit-take when Apple announced the M1 Ultra today. Probably not, unless it was the speed at which Apple brought the idea to market.

I wonder, honestly, if Intel is even able to compete here. System-on-a-Chip (SoC) constrains versatility; if your chip has to work in many places, it can’t optimize for any.

But I raise my glass tonight to the silicon people at Apple. They are punching the rest of the industry in the face right now. Maybe I’m a homer, but what they have done speaks for itself.

Bitcoin is Cool, but It’s not Money

Posted on by

The subject of blockchain technology in general, and cryptocurrency in particular, has come up a few times lately, and I’ve been doing some reading. When you look, you mostly find stuff that does a bad job describing what blockchain is, before jumping to some particular use for it – generally cryptocurrency, and why you should buy some.

But “blockchain” is the second-least important word in this discussion. “Cryptocurrency” is the least important. Blockchain is a way to achieve a utopian dream, and it’s the dream we will talk about today. The dream is the Distributed Ledger – a system where there isn’t some central institution who decides who owns what, instead that information is all kept in an encrypted ledger that we all share and maintain, and magically we can only read the parts of the ledger that are our business to read.

All the blocks and chains and whatnot are an implementation detail that is not really that important. But… later we will see that some implementation details matter a lot.

Let’s talk about the distributed ledger. Instead of some bank tracking how much money is in everybody’s account, there are thousands of copies of the ledger, spread around the world, immune to deprivations of institutions who use the ledgers to control us. It’s a pretty sweet idea. Better yet, ideally even when the ledger is spread around the world, only the right people can read the parts about you. For all the rest, the ledgers just have to agree.

To make this happen there are two key concepts: redundancy and consensus. Redundancy we just spoke of. Thousands, maybe millions of instances of the ledger, all verifying that they are the same, even if they can’t see the individual transactions.

But imagine if Ronald McDonald decides to give a Bitcoin to Mayor McCheese. He duly records the transaction and that information propagates through the network as all the instances of the ledger are updated. But at the same time, on another ledger it is recorded that in fact Ronald gave that same Bitcoin to the Hamburgler! I heard that gasp of horror, and it is well-placed!

With every distributed ledger, there has to be a way to resolve discrepancies that through sloppiness, bad timing, or malice will inevitably arise. Eventually all those ledgers have to concur about what actually happened. Therefore, the people who run the system need to make it difficult for the bad guys to overwhelm the honest transactions. They need to allocate deciding power based on some resource they control that makes the holders invested in the success of the platform.

In the case of Bitcoin, that resource is pure computing power. Solve math puzzles, get Bitcoins. Once you have Bitcoins, you will protect them. So to push false transactions onto Bitcoin, you would have to to solve those math puzzles faster than everyone else on the network combined.

That would not be easy. I read an estimate today that the current Bitcoin puzzle-solving economy, which uses extremely efficient hardware designed to solve these particular problems and nothing else, is currently chewing through the amount of electricity consumed by the entire country of Austria – at the low end. So to fool Bitcoin, you’d need about 1.1 Austrias (at the low end) of power. That’s pretty impractical, and that’s what keeps your Bitcoins safe.

Or, to defraud the system you could find a different way to generate sha256 hashes (that’s the Bitcoin puzzle). If you came up with a new way to do that calculation that took 1% of the power, you could destroy Bitcoin. Quantum computing would trash Bitcoin, but the latter will be long gone before the former arrives on the scene. Yep, Bitcoin will be long gone.

There are other ways for distributed ledgers to form consensus that are far less carbon-awful. In fact, there’s a currency that was recently announced that awards blocks (coins) for each ton of CO2 sequestered. And away from cryptocurrency, the distributed ledger promises to transform some really complex problems like adaptive energy grids and a world filled with self-driving cars. All the new cryptocurrencies are finding less ecologically-disastrous ways to manage consensus. Etherium is launching a new less-eco-awful version of their currency, and leaving their old version to the winds of fate. The power bill will eventually destroy Bitcoin.

I mentioned above redundancy and consensus. We have seen that consensus can be extremely expensive. New distributed ledgers are working to reduce that cost. But redundancy also has a cost.

All the ledgers have to share information, constantly updating each other. For the blockchain implementation, each update itself requires a great deal of computation to ensure security — digital signatures, hashes, more signatures. Recording a single transaction in thousands of ledgers eats up CPU time, to the point where processing a single Bitcoin transaction takes the juice to run your house for a week. (Actually, a German house for a week, whatever that means.)

And this is where we get to “Bitcoin is not Money”. Despite demanding the power of a European nation to operate, Bitcoin can only process a few transactions per second. Like, less than ten. How many credit card transactions take place every second? A global-scale distributed ledger makes each transaction very expensive. It is simply impossible for Bitcoin to be a factor in everyday commerce.

EDIT: In fact, bitcoin intentionally adjusts the difficulty of adding a block to the chain so that one 1MB block is added every ten minutes, so that transactions can be “digested” and shenanigans rooted out. This puts a very hard limit on the number of transactions that can be added to the chain, and as computing power increases, the difficulty of adding a block to the chain increases with it. Bitcoin by design cannot handle the transaction rate of an actual currency.

(Although I have to say that since you can know the entire history of each coin, you could, for instance, simply refuse to accept any coin ever touched by a company that dealt with blood diamonds, effectively making their money worth less. That is the true power of the distributed ledger. Someday it will be real.)

When it comes right down to it, our current attempts at the distributed ledger are way better at things that aren’t money – things where there is value in decentralizing, but they don’t move as fast as we need money to move. Or things that move fast but in a smaller context, like an office or a company.

Or, God help us all, Non-Fungible Tokens. A topic for another day.

When you hear about the ways blockchain technology will change the world, quietly, to yourself, substitute the term “distributed ledger”. That is the idea that has the power to change so many things for the better, and it’s a lot easier to fit in your head. Blockchain is an implementation of that idea, but it’s got warts big enough to mostly obscure the magical toad underneath. Moore’s Law may finally get us to the promised land, but computers will literally have to be a million times faster than they are now to turn blockchain-based cryptocurrency into actual money. My bet is now that we have seen the value of the distributed ledger, we will find a better way to accomplish it. And that’s pretty exciting.

Just Another Commute in Silicon Valley

Posted on by
Reply

Today as I used public transportation to go to work, I saw five robotic cars, operated by three different companies.

Three of the five cars were Urban Automated Driving vehicles operated by Bosh and Daimler, running (human monitored) robot taxi service along the same corridor my bus takes. The Mercedes c-class vehicles are equipped head-to-toe in lidar units (lidar is like radar… with lasers!) and if I loaded the app I could ride in one. Which… is tempting, for purely journalistic reasons. My biggest question: How bored is the human monitor? Super-bored means things are going smoothly; super-bored also means that the human will never spot the emergency in time.

The second company was Nuro. The vehicle was a Toyota or whatever with sensors all over it, but what the company is actually developing is an autonomous vehicle that doesn’t have seats in it at all. Their dream: order your groceries and have the robot bring them to you. The vehicles are electric and since there is no need to account for human comfort, they could theoretically be much, much cheaper. It is easy to imagine that many companies that sell stuff would be interested in having something like that. Nuro’s Web site doesn’t have a lot of information, except for a pdf with a major discussion of safety (that I didn’t read).

There was a third, but my most humble apologies, dear readers, I don’t remember the company name painted on the car. It was not Google; I haven’t seen one of those in a while. Apple, should they even still have experimental cars, would keep them anonymous (which, as I think about it, would be just as definitive as putting a neon logo on the side — no other company would operate vehicles with a bunch of extra gear strapped on without missing the chance to brag about it).

As cities go, San Jose and the rest of the unplanned, disorganized sprawl that is Silicon Valley is… meh. And the cost to live in meh is staggering. But one thing I do enjoy is that it feels like we are just a little bit closer to the future here. And there’s nothing like Bay Area traffic to make you really, really, look forward to the day when people are not in control of giant deadly machines.

The Guy on the Corner

I grew up in a small town, but one of my first visits to a large city carries with it an enduring memory. A man, skinny and bedraggled, on a street corner, shouting obscenities into his hat. I was just a kid back then, and didn’t understand the tragedy that man represented. I was just perplexed. I learned, somehow, later, to be afraid of people like that — maybe the reaction of the people around me that day informed that fear. Which is awful.

Yesterday, walking down the street in San Jose, there was another man standing on a corner shouting into the air, a stream of profanity. I just assumed he was on the phone.

Two Things I Learned Today

Posted on by

  1. MapQuest still exists!
  2. MapQuest really sucks.

I learned the former when using the Web site to report for jury duty in Santa Clara County. Links to the locations of the courthouses take you to MapQuest.

For a brief explanation of the latter, MapQuest is overrun with intrusive advertising, and the “get directions to a place” feature does not include public transportation.

My next post is likely to be observations on the Wheels of Justice. Oh boy!

Took My Data Privacy Training Today

Posted on by
Reply

The European Union is enacting a new policy concerning the way companies treat the personal information of their customers. Today I went through the training to make sure I understood what those rules meant to me.

Spoiler: nothing new. But there are a lot of other companies in this neighborhood that are probably scrambling. I’ll name names later.

The new privacy training was pretty much exactly the same as the previous data privacy training I have gone through, with the exception that there is a new report to fill out to make the decision process on using customer data visible to the outside world. There is also a new portal so people can see all the data my employer has collected on them, and request that that data be deleted.

But overall, the new privacy regulations in Europe might have been written by my company, they match our existing policy so closely.

Remember back when Google was “accidentally” collecting information about open home WiFi networks? Accidentally in this case means accidentally creating database tables and queries to store that information. I mean hey, accidents happen. That was a while ago, but that shit is really not going to fly now.

Hey! So much for “later”. I’m naming names.

The regulations go something like this:

  1. You have to spell out what you will be using the data for BEFORE you collect it.
  2. You have to protect that data.
  3. You have to let people see the data and tell you to delete it.

The Google thing was years ago. (There are plenty of current investigations, however.) But hey, remember last week when an Android user discovered Facebook was recording the recipient and duration of all his phone calls? Yeah, the beat goes on. In the aftermath of that I downloaded my own information and there were only a couple of surprises, none shocking. Hint: I don’t use Android.

At Google they must HATE Facebook for being so damn sloppy and leaking data all over the place, rather than just efficiently selling it. Regulators are swarming! Maybe now Google might consider putting in place basic security measures to prevent apps from rooting through shit that is none of their business.

My Facebook information was mostly unsurprising, but I suppose it’s possible that in the last few days Facebook has decided that fraudulently withholding some of the data they have collected on me is better than confessing to all of their shenanigans. Ironically, the ability for people to download their information was probably implemented by Facebook to comply with the new regulations. Sadly for them, the more people who download their personal info, the more trouble will arise for Facebook.

I encourage everyone to request a data download from Facebook. And from Apple, and from Google, and from Amazon. Probably Ebay, too, and the list goes on.

For the rest of this episode, I am full-on partisan. Just so you know. But there’s nothing I’m going to say that is not easily documented.

Google has a vast amount of data on you. If you use Google Wallet, downloading your data might be downright scary; if you use ApplePay instead you will find a big empty nothin’ concerning your spending habits. Apple built it so that it was not possible for them to learn anything about you from your spending. It was not easy to do.

I work for Apple. I am proud that my company puts privacy over profit — that HomeKit is slow to be adopted because it protects privacy and home-gadget manufacturers want to profit from personal data (and the hacking-resistance of HomeKit is more expensive to implement — something I’m also fine with), and I am proud that ApplePay was first out of the gate but isn’t growing as fast as the competitors because privacy requirements make it harder for banks to join in. Apple is losing money protecting privacy.

Unless protecting privacy becomes law. Then, suddenly, my employer is in the catbird seat, having built its information structure around privacy from the get-go. Apple has put a lot of systems in place to make sure they cannot collect large categories of personal data. Currently that data is an asset that they are failing to exploit. In the future, that data will be an onerous responsibility for any company that holds it. I hope so, anyway.

Assembling an iomega Mac Companion Enclosure

Posted on by
20

One of the big-ass hard drives we use for backup has started to make scary noises. Not the kind of sounds you want to hear from a drive that holds important data for our family and for a few of friends around the country as well. It was time to start looking for a replacement drive. One thing I wanted to do was have a clear upgrade: with the new setup I will not have to fear the catastrophic consequences of a single drive failing.

A note on levels of catastrophe: some might think that losing backup data is an inconvenience. In the same way you could think that losing the co-piolot of an airplane is an inconvenience. But with the backup compromised, risk of disaster has gone up exponentially. At Muddled Ramblings and Half-baked Ideas we take that shit seriously as we skulk in our secret bunker, buried deep beneath a trailer park next to a sprawling cemetery, ready for the Zombie Apocalypse to begin.

There are fancy enclosures that hold several drive units and use a variety of schemes that fall under the general acronym RAID to protect data from the failure of a single drive. Most of those enclosures have loud fans, and all of them cost a lot of money. Where does a cheap bastard go when he wants RAID 5, quiet and cheap? He buys a bunch of inexpensive but high-quality disks, puts them in inexpensive but high-quality quiet enclosures, and uses SoftRaid to turn them into a single virtual disk with reasonable protection from disaster.

After a little research, I found the right drives (Seagate bulletproof datacenter-rated blah blah blah) and the right enclosure: the iomega Mac Companion. What is great about this enclosure is that it has TWO firewire connectors, so you can daisy-chain them and connect many drives to a single firewire port on the host computer. Music to cheap-bastard ears, and not found on other enclosures at any price. Plus, you can buy them cheap on eBay in any quantity you might want, while supplies last.

There’s a catch, of course: iomega is defunct, and never officially sold this enclosure without a drive already installed. The packaging looks as though they might have been planning to sell empty enclosures, but the documentation (and even some of the text on the box) is clearly written with the assumption that the drive is already in there and everything is assembled.

So, you have packaging clearly designed to contain an empty, partially-disassembled hard drive enclosure, and instructions clearly for a pre-assembled unit. Weird. Perhaps some last, desperate attempt to sell an inventory of enclosures the company could no longer afford to fill. The only intern left to handle the packaging had no idea what to do about the instructions. We’ll never know the whole story.

But there’s a glut of quite capable hard drive enclosures out there now, and I bought some of them. As for assembly, there are no instructions. Not in the box, not online. You’re on your own, buddy. Until now! By my third enclosure, assembly was actually pretty easy. As a public service to anyone else who might have jumped on this deal, here are step-by-step instructions. You don’t have to thank me, it’s what I do.

Step 0: Survey the stuff.
When you open the box you will see parts in two groups: the top and the bottom. The bottom section includes the plastic base, the metal housing, and the circuit board, which is attached to the bottom of the aluminum inner shell. The top section has an aluminum inner shell top and the plastic lid for the enclosure.

Let’s take a moment to visualize the final product. A hard drive mechanism, inside a protective metal inner shell, inside a sturdy enclosure with lights on the front. With that in mind, we will be building from the middle out. (Yes, I thought of Silicon Valley when I wrote that.)

Step 1: Start by disassembling the bottom parts even further. Carefully pop the plastic base out of the outer metal housing, then slip the circuit board with inner shell off the plastic base. This is the step that took me three tries to learn. After this, everything is actually pretty obvious.

Step 2: Set the hard drive onto the white shield over the circuit board and slide it forward onto its connector.

Step 3: Slide the top inner shell over the drive unit with the little pigtail cable sticking out the slot in the side. At this point, you have something that looks like this:

IMG_0420

Step 4: If you look at the picture, you will see a screw holding the drive in place. The enclosure does not include the screws, but they are a standard size. I’m not sure what size, because I had some in my hardware collection, but you can figure that part out. In fact, in the first drive I assembled, I didn’t use any screws at all. I resolve to not use that drive as a maraca, and all will be well. But if I had it to do all over again, I’d screw those bad boys down.

Step 5: Slip your well-shielded hard drive assembly back onto the plastic base. Fiddle with things until the connectors line up with the holes in the base.

Step 6: The circuit board on the end of that pigtail cable hanging out the side actually has four LED’s on it. The tiny circuit board fits into a slot in the plastic base. Note that there is a wee indentation in the board at one end; that part goes DOWN, where it seats neatly on a plastic fin:

IMG_0415

Step 7: Now it’s time to put the outer metal housing on. There’s an odd plastic bit you set aside earlier with four little shafts sticking out. Those go into the holes in the front of the housing, and as you put the housing down over the plastic base the odd plastic bit will slide into the holder directly in front of the circuit board from step 6.

IMG_0422

Step 8: At this point, everything is connected and should be functional. Before passing the following Point of Maybe-No Return, I plugged in each unit and made sure it spun up happily.

Step 9: Snap on the lid. You’re finished! Woo!

I have no idea how to remove the lid again; and hopefully I’ll never have to learn. Now I have a lot of room for data. Setting up my poor-man’s RAID will likely have to wait until next weekend, and hopefully will be simple enough that I don’t need to write a how-to. In the meantime, I hope this is helpful to those who find themselves with a question mark hovering over their heads as they stare at the parts they have just received.

My spelling correcter just changed m’fuckin’lord to mmfnuckin’lord. It does not change m’fuckin’ to mmfnuckin; the lord part is apparently important. I’m sure there’s something to learn from this.

Thanks!

So close…

About to purge the last of the Windows from the house, and say goodbye to the flimsy crap Asus laptop. The last task: getting it to talk on the network so we can move everything over.

It worked on the network two days ago. It has all sorts of other problems, far too many to enumerate here, but at least we were able to move files.

Now, not so much. Along with this happy message:

A problem is preventing the troubleshooter from starting.

Yay Microsoft!

Thanks!

Will the World Break in 2016?

Well, probably not. The world isn’t likely to break until 2017 at the earliest. Here’s the thing: Our economy relies on secure electronic transactions and hack-proof banks. But if you think of our current cyber security as a mighty castle made of stone, you will be rightly concerned to hear that gunpowder has arrived.

A little background: there’s a specific type of math problem that is the focus of much speculation in computer science these days. It’s a class of problem in which finding the answer is very difficult, but confirming the answer is relatively simple.

Why is this important? Because pretty much all electronic security, from credit card transactions to keeping the FBI from reading your text messages (if you use the right service) depends on it being very difficult to guess the right decoder key, but very easy to read the message if you already have the key. What keeps snoops from reading your stuff is simply that it will take hundreds of years using modern computers to figure out your decoder key.

That may come to a sudden and jarring end in the near future. You see, there’s a new kind of computer in town, and for solving very specific sorts of problems, it’s mind-bogglingly fast. It won’t be cheap, but quantum computers can probably be built in the near future specifically tuned to blow all we know about data encryption out of the water.

Google and NASA got together and made the D-Wave two, which, if you believe their hype, is the first computer that has been proven to use quantum mechanical wackiness to break through the limits imposed by those big, clunky atoms in traditional computing.

Pictures abound of the D-Wave (I stole this one from fortune.com, but the same pic is everywhere), which is a massive refrigerator with a chip in the middle. The chip has to be right down there at damn near absolute zero.

The chip inside D-Wave two was built and tuned to solve a specific problem very, very quickly. And it did. Future generations promise to be far more versatile. But it doesn’t even have to be that versatile if it is focussed on breaking 1024-bit RSA keys.

It is entirely possible that the D-Wave six will be able to bust any crypto we have working today. And let’s not pretend that this is the only quantum computer in development. It’s just the one that enjoys the light of publicity. For a moment imagine that you were building a computer that could decode any encrypted message, including passwords and authentication certificates. You’d be able to crack any computer in the world that was connected to the Internet. You probably wouldn’t mention to anyone that you were able to do that.

At Microsoft, their head security guy is all about quantum-resistant algorithms. Quantum computers are mind-boggling fast at solving certain types of math problems; security experts are scrambling to come up with encryption based on some other type of hard-to-guess, easy-to-confirm algorithm, that is intrinsically outside the realm of quantum mojo. But here’s the rub: it’s not clear that other class of math exists.

(That same Microsoft publicity piece is interesting for many other reasons, and I plan to dig into it more in the future. But to summarize: Google wins.)

So what do we do? There’s not really much we can do, except root for the banks. They have resources, they have motivation. Or, at least, let’s all hope that the banks even know there’s a problem yet, and are trying to do something about it. Because quantum computing could destroy them.

Eventually we’ll all have quantum chips in our phones to generate the encryption, and the balance of power will be restored. In the meantime, we may be beholden to the owners of these major-mojo-machines to handle our security for us. Let’s hope the people with the power to break every code on the planet use that power ethically.

Yeah, sorry. It hurts, but that may be all we have.

Thanks!

A Secure, Undisclosed Location for my Stuff

I take a bunch of pictures. Each image is many megabytes. It adds up. I have a big-ass hard drive or two, but each image should be on multiple hard drives, and not all in one room.

Then there’s DropBox. That’s a service that makes one folder on your computer also exist out there in what the kids are calling the cloud. Which is cool from a redundancy standpoint, but what I’d really like is to not have to keep the files locally at all. I want something that looks to my computer exactly like a hard drive, but is really some gee-whiz redundant storage solution out there somewhere.

There are a couple of requirements:

  • It really does act just like a hard drive
  • It is encrypted with a key that I generate; the provider does not have that key. No one has that key but me.
  • There is a plan and escrowed funds so that if the host goes belly-up, I get my data back.

I don’t even know where to start looking. Suggestions?

Thanks!
