Lunchtime reading

Lots of stuff crossed my inbox this morning:

Back to my wonderful, happy software debugging adventure.

Shut. The. Front. DOOR.

Via Raymond Chen, Eric Shlaepfer built a 6502 emulator out of full-size components:

The MOnSter 6502

A dis-integrated circuit project to make a complete, working transistor-scale replica of the classic MOS 6502 microprocessor.

How big is it?

It's a four layer circuit board, 12 × 15 inches, 0.1 inches thick, with surface mount components on both sides.

Can you hook it up inside an Apple ][ and run Oregon Trail?

No, not directly. It's neat to think of plugging the MOnSter 6502's in-circuit emulator (ICE) in-circuit replica (ICR) cable directly into a socket inside an Apple ][, but that wouldn't actually work. The Apple ][ design relies on a number of clever tricks that derive timing for video generation and peripheral control from the main clock signal — all of which will fail if you need to run at a slower speed.

Are you going to make one out of vacuum tubes next?

No.

Make sure you watch the 2-minute video.

Morning reading list

Before diving back into one of the most abominable wrecks of a software application I've seen in years, I've lined up some stuff to read when I need to take a break:

OK. Firing up Visual Studio, reaching for the Valium...

Lunchtime reading list

While trying to debug an ancient application that has been the undoing of just about everyone on my team, I've put these articles aside for later:

Back to the mouldering pile of fetid dingo kidneys that is this application...

The tragedy of Agile

Uncle Bob riffs on Martin Fowler's speech at Agile Australia this week. He is saddened:

It was programmers who started the Agile movement as a way to say: “Hey look! Teams matter. Code should be clean. We want to collaborate with the customer. And we want to deliver early and often.”

The Agile movement was started by programmers, and software professionals, who held the ideals of Craftsmanship dear. But then the project managers rushed in and said: “Wow! Agile is a cool new variation on how to manage projects.”

There’s an old song, by Alan Sherman, called J. C. Cohen. It’s about a subway conductor who did such a great job at pushing people into the train cars, that he pushed the engineer out. This is what happened to the Agile movement. They pushed so many project managers in, they pushed the programmers out.

The programmers continued to pursue Agile as it was originally conceived. Read the opening line of the Agile Manifesto: “We are uncovering better ways of developing software by doing it and helping others do it.” It is Software Crafts-men and -women who are continuing that work. It’s not the project managers in the Agile movement. They’re off pursuing something else?

He has hit on the sadness all us old craftsmen feel when we encounter Management.

The next war

Via Bruce Schneier, retired USMC Colonel Mark Canclan has authored a report outlining what threats we're likely to face in the next few years, and how to cope with them. He includes some chilling strategic possibilities:

The cyber attacks varied. Sailors stationed at the 7th Fleet' s homeport in Japan awoke one day to find their financial accounts, and those of their dependents, empty. Checking, savings, retirement funds: simply gone. The Marines based on Okinawa were under virtual siege by the populace, whose simmering resentment at their presence had boiled over after a YouTube video posted under the account of a Marine stationed there had gone viral. The video featured a dozen Marines drunkenly gang-raping two teenaged Okinawan girls. The video was vivid, the girls' cries heart-wrenching the cheers of Marines sickening And all of it fake. The National Security Agency's initial analysis of the video had uncovered digital fingerprints showing that it was a computer-assisted lie, and could prove that the Marine's account under which it had been posted was hacked. But the damage had been done.

There was the commanding officer of Edwards Air Force Base whose Internet browser history had been posted on the squadron's Facebook page. His command turned on him as a pervert; his weak protestations that he had not visited most of the posted links could not counter his admission that he had, in fact, trafficked some of them. Lies mixed with the truth. Soldiers at Fort Sill were at each other's throats thanks to a series of text messages that allegedly unearthed an adultery ring on base.

The report is fascinating, and the vignettes that Canclan describes should be keeping US military and defense personnel up at night.

Primer on Multi-Factor Authentication

Via Schneier, Stuart Schechter has an excellent article for MFA n00bs people new to multi-factor authentication:

Many online accounts allow you to supplement your password with a second form of identification, which can prevent some prevalent attacks. The second factors you can use to identify yourself include authenticator apps on your phone, which generate codes that change every 30 seconds, and security keys, small pieces of hardware similar in size and shape to USB drives. Since innovations that can actually improve the security of your online accounts are rare, there has been a great deal of well-deserved enthusiasm for two-factor authentication (as well as for password managers, which make it easy to use a different random password for every one of your online accounts.) These are technologies more people should be using.

However, in trying to persuade users to adopt second factors, advocates sometimes forget to disclose that all security measures have trade-offs . As second factors reduce the risk of some attacks, they also introduce new risks. One risk is that you could be locked out of your account when you lose your second factor, which may be when you need it the most. Another is that if you expect second factors to protect you from those attacks that they can not prevent, you may become more vulnerable to the those attacks.

Before you require a second factor to login to your accounts, you should understand the risks, have a recovery plan for when you lose your second factor(s), and know the tricks attackers may use to defeat two-factor authentication.

Read it, and then send it to all of your non-technical friends, unless they happen to be politicians in a certain elephantine party in the U.S.

More sad but true news about politicians

Shocking, I know, but politicians seem comically unaware of how technology works:

We’re now a dozen years past the infamous “series of tubes” speech. Yet our political leaders still don’t seem to have learned much about those “tubes” or the cyber-sewage that frequently flows through them.

Consider a recent, noncomprehensive history.

These days Trump lashes out at private companies that suspend nut jobs and neo-Nazis, decrying that “censorship is a very dangerous thing & absolutely impossible to police.” But in what feels like a million years of crazy ago, then-candidate Trump said he planned to hobble recruiting by the terrorist Islamic State by asking Bill Gates to “clos[e] that Internet up in some way.”

This was a baffling proposal, not only because Chinese-style, government-enforced Internet censorship would run afoul of the First Amendment. The other problem was that the Microsoft founder-turned-philanthropist does not, uh, “control” the Internet.

Don’t get me wrong, there are some politicians out there who seem to know their way around the information superhighway. Rep. Ro Khanna (D-Calif.), who represents part of Silicon Valley but has called for stronger privacy rights, is among them. Sens. Richard Burr (R-N.C.) and Mark R. Warner (D-Va.), as Senate Intelligence Committee chair and vice chair, respectively, have shown an inclination to ask tougher questions of tech companies on Russian interference.

But the problems infecting the tech sector go well beyond those limited areas, alas. And, generally speaking, our policymakers are ill prepared to protect the public from those who wish us harm — or even from companies willing to profit off that harm.

None of this is really new. Politicians typically know less than most people about the daily lives of the people they represent. What's different, at least as far as the governing party in the U.S. goes, is that they're proud of their ignorance. That is what we should be afraid of.

Policies are changing work, not technologies

Economic historian Louis Hyman describes how the choices people in government and business make actually lead technological change, for some pretty obvious reasons:

The history of labor shows that technology does not usually drive social change. On the contrary, social change is typically driven by decisions we make about how to organize our world. Only later does technology swoop in, accelerating and consolidating those changes.

This insight is crucial for anyone concerned about the insecurity and other shortcomings of the gig economy. For it reminds us that far from being an unavoidable consequence of technological progress, the nature of work always remains a matter of social choice. It is not a result of an algorithm; it is a collection of decisions by corporations and policymakers.

In the last 10 years, 94 percent of net new jobs have appeared outside of traditional employment. Already approximately one-third of workers, and half of young workers, participate in this alternative world of work, either as a primary or a supplementary source of income.

Internet technologies have certainly intensified this development (even though most freelancers remain offline). But services like Uber and online freelance markets like TaskRabbit were created to take advantage of an already independent work force; they are not creating it. Their technology is solving the business and consumer problems of an already insecure work world. Uber is a symptom, not a cause.

Policies, of course, can be changed.
