Panic's stevenf: Time to Dump FTP

Merlin — Mon, 14 Jul 2008 15:45:38 -0400

stevenf.com (“Don’t Use FTP”)

Steven Frank, one of the boys wonder behind Panic and their excellent Transmit app says it’s high time to dump FTP in favor of its smarter, sexier sister, SFTP. Of which Steven says “It’s secure, it’s consistently implemented, and it’s machine-readable.”

A lot of people who have used FTP daily for years are surprised to learn that they’re sending everything in the clear – that means the stuff you’re uploading as well as your actual password. Makes you think twice about what you’re throwing through the air as you update your blog templates via “free WiFi.”

Steven says:

If your host doesn’t support SFTP, you should ﬁnd a different host. It’s not hard to support, and it’s ridiculous to force people into using insecure protocols in the year 2008. Ask them, for example, why they don’t support telnet. FTP is no better.

FTP has served us well, but it’s time to move on. You wouldn’t use a 23 year old computer to do your work, so don’t use a protocol from the same vintage. Demand modern transfer protocols from your host.

I agree. If you’re unsure whether your host will let you do SFTP (and SSH in general), ask. You may indeed need special permission (many providers “jail” garden-variety users in a way that disallows SSH without special permission). You may also need to ﬁnd the correct port. On my host, A2, for example, you have to run SSH and SFTP on the unconventional port 7822, but it works like a charm once you’re up.

Great suggestion, Steven. Worth getting the word out.

Email Insanity & the 0.001 Challenge

Merlin — Thu, 24 Apr 2008 09:11:46 -0400

Via a Toot by Jeff Atwood comes this thoughtful post by Tantek Çelik on how email is no longer working for him. His ﬁrst reason is a biggie:

1. Point to point communications do not scale.

All forms of communication where you have to expend time and energy on communicating with a speciﬁc person (anything that has a notion of “To” in the interface that you have to ﬁll in) are doomed to fail at some limit. If you are really good you might be able to respond to dozens (some claim hundreds) of individual emails a day but at some point you will simply be spending all your time writing email rather than actually “working” on any thing in particular (next-actions or projects, e.g. coding, authoring, drawing, enjoying your life etc.)

This is one reason I’m getting attracted to using Get Satisfaction as a way to expose help issues to a large group of helpers and helpees (BTW, we’re just getting started on GS – FAQs and more will be coming soon). I’m also realizing that this is why I (and Jonathan Coulton and probably you) struggle with holding up dozens of one-on-one conversations – it locks up your attention and its fruits in thousands of inaccessible alcoves. And truly, that does not and will not scale.

But, y’know, as I read Tantek’s post, alongside his “Communication Protocols” notes, I found myself returning to a pet theory that I’ve been too embarrassed to lay out in a real post. But what the heck, I’ll capture some notes and you can tell me what you think:

I suspect that email encourages people to act insane.

Right this minute, you can create an email of unlimited length covering topics of unlimited scope and then send it to unlimited numbers of people – whom you may or may not even know – all at absolutely no cost to you. There is also no prohibition or boundary of any kind on how you phrase that email. There’s no formal penalty or even feedback for when you’re using email inappropriately (e.g. the dirty look that you’d get if you said something this weird to someone’s face). Plus, of course, YOU get to decide (at least in your own head) exactly how quickly all those people should be getting back to you about whatever it is you emailed them about. And you can do this pretty much any time you want and as many times a day as it suits you. No Limits.

An optimist would say this indicates what a wonderfully ﬂexible tool email is. But, a pessimist with 1500 unread emails will point out that this Wild West of Communication seems to bring out the nut in people.

As I say, there must be something about email’s unusual combination of intimacy and distance that can get people very emotionally engaged in hammering out demands in an email message. And not just ﬂames – I’m talking about people whose de facto style is borne out of an uninhibited conduit between thoughts, emotions, or desires and the email medium that helps them convert that into some kind of request.

How and why this is related to Tantek’s post, I’m not entirely sure. But I think there’s some common ground here. Especially as this relates to that one-on-one idea and why it doesn’t scale.

Email culture and etiquette – if there is such a thing – occurs when people have a sense of how their behavior will be seen and evaluated by anyone who is not themselves. The reason most of us wear pants to the grocery store is the same reason that some people think very hard about every word that goes into their email messages and what it will mean when people read them. They understand that the message should be more about the recipient than themselves. And the Great Ones will take the time to get the tone right too – to phrase things so that misunderstandings and unintentional emotional provocations don’t occur.

But if – even without realizing it – you see email primarily as a one-on-one medium for venting some…thing that’s on your mind, you’re going to produce a lot of electronic madness. Especially if you think no one is watching.

I’m going to think on this some more, but I’ll close with a related thought on why this all goes straight back to Time & Attention 101.

Any system without scarcity or limitation will eventually suffer at the hands of people who aren’t overtly aware of boundaries – or who actively choose to break those boundaries because they can. Limitations in a communication medium not only make you think a little harder about what you have to say, they also encourage you to focus on what you and your recipient really need out of the exchange.

While I’m not suggesting anything as extreme as the ﬁve-sentence email, I wonder if this might be a fun exercise to try for a day:

The 0.001 Challenge

Imagine that the person receiving the email you’re composing receives 1,000 other message each day more or less identical to yours. What would you do to distinguish yours from the others? What change would make your email amazingly easy to deal with and not insane? Does the content of your email belong someplace else? Like an SMS, a face-to-face meeting — or maybe even in an angry, venting screed that you never send.

Clever web dev trick for checking browser history

Merlin — Fri, 08 Feb 2008 13:27:22 -0500

Sniff browser history for improved user experience

Talk about sufﬁciently advanced technology. Although you will surely see this post linked many times this week, I have to throw in my own kudos. Fantastic trick, Niall!

In a nutshell, Niall shows how you can use a combination of CSS and JavaScript to selectively display information based on previously visited URLs in your visitor’s browser history. Have you been to Digg? Then Niall’s site displays a “Digg This” badge (and, importantly for Niall’s purposes, not 100 other badges for sites you haven’t used).

Try Niall’s live example to see this stunner in action.

Dang. That sound you just heard? That’s a few million people scurrying to hit “Clear History.” Terriﬁc work, Niall – totally clever.

Now, regrettably, I suspect the race begins for seeing how horribly something like this can be abused.

Adventures in $40 eyeglasses

mathowie — Thu, 29 Nov 2007 07:37:04 -0500

Last year, I stumbled upon a blog post about buying prescription eyeglasses online. It sounded too good to be true: you could get any frames you wanted quickly and cheaply, and the comments were ﬁlled with optometrists freaking out. Eventually, the author launched a dedicated blog for it called Glassy Eyes. When the site was recently mentioned on MetaFilter right around the time I was getting my 2-year exam, I decided to take the plunge myself and order some glasses online.

Why Buy Online?

As a lifelong near-sighted person, prescription eyeglasses and especially prescription sunglasses have long commanded a high premium due to the seemingly precise and scarce nature of creating them. Until a few years ago, I only had two options for eyewear: my optometrist (here’s an employee admitting they pay less than ten bucks per pair) or a 1-hour place like Lenscrafters (which is part of a multinational monopoly). About ten years ago, when I was fresh out of college and scraping by month to month with my ﬁrst real job, I broke my only glasses and had to pay $400 for an emergency pair (that were ugly and I hated and I wore for two more years before I paid off the old ones and could afford new ones). For far too long, glasses have been expensive.

Today things are different, with Coscto and Walmart bringing prices down to the $100-150 range for frames/lenses and they serve as a good economical option to the mainstays. With the advent of online sellers, it’s now possible to get a decent set of specs for anywhere between $20-$100. The online selection is phenomenal as well.

Get Your Measurements Right

First thing you need is an up-to-date prescription. Though people usually get one every 2+ years, most optometrists will only honor them for a up to a year afterwards. If you’re getting one soon, you’re in luck, because you can go in knowing a little more than the average patient. When you’re done with the standard exam, ask the eye doctor or an assistant if they can give you your pupil distance. It’s a simple matter of looking through a binoculars-like device that measures the distance between your pupils. It should be a number in millimeters and be sure to write it down either on the prescription or on a piece of paper (if you get two numbers, that’s right/left which you can add up to be the PD). If you forget to ask or already visited an eye doctor recently, you can measure the PD yourself, by simply printing out a ruler and looking in a mirror (or taking a photo of yourself with the ruler below your eyes).

Armed with your prescription and your PD, you’re all set for ordering any glasses you want online.

Measure What You Have, Know What You Want

It helps if you have two things: a bit of fashion sense and a measuring tape. I personally loved my last pair of eyeglasses (paid $500 at a fashion eyewear store two years ago), but they were a bit too short in the lens height department which became annoying as I could often “see” below my lenses during common everyday tasks. The glasses ﬁt well otherwise and armed with my wife’s soft sewing measuring tape, I took millimeter measurements of all aspects of my old glasses: lens height, lens width, length of bridge (distance between lenses), total width of lenses plus bridge, and the length of the side arms.

Now that I had my prescription (with PD), and my frame measurements, I copied it into a text ﬁle and kept it open as I shopped online. I knew I needed lenses around 53mm wide, about 20mm apart, and the arms needed to be at least 135mm long. My old too-short lenses were only 26mm tall, so I was looking to get something with around 30mm of lens height. Some online shops let you plug all these numbers in and specify what you want to search on as the most important (I did “lens height must be at least 28mm” search), but most all online shops will display the measurements below each frame, which should help narrow down your searches.

In terms of frame design, I knew I wanted a half-rim frame (metal/plastic top and arms, clear lens below) or a full plastic frame, and most every online shop categorizes frames for sale by their construction in this way. Knowing that you want frameless glasses or nerdy plastic retro glasses deﬁnitely helps making shopping online easier because some online shops can offer 500+ different varieties of just one style of eyewear. If you’re not quite sure what you want, you might want to browse a real eyeglasses store for a bit to narrow down your desires.

Ordering Up, Playing the Waiting Game

Once you ﬁnd something you like and it’s about the right size, it’s time to order. Plug in your prescription details (if you can’t make them all out, most sites have helpful tips on deciphering a prescription) and pick out your options. The one option that will turn a $20 pair of glasses into an $80 pair is the lens choice. Be careful when picking out a lens because there are plenty of add-ons you might or might not want. Generally I pay for the highest level of non-glare coatings and I usually pick the middle of the thin-lens options (my personal prescription rules out the thinnest, lightest lenses). Most of my online glasses have run about $50 or so.

Shipment and fulﬁllment is generally pretty good. I ordered ﬁve pairs of glasses total, from four different retailers and started receiving pairs about a week later. The longest one was maybe three weeks, which is about normal for most optometrists, so in general ordering online was faster than higher cost traditional options.

The Verdict?

I used to wear the same glasses for 3-4 years between changes so I’m ﬁnding it incredibly liberating to pick from ﬁve different sets of glasses each morning. I have a couple fashionable pairs for going out, a couple understated ones for working and I can even take a chance with a wacky retro frame if I’m in the mood. All told, my glasses cost me from a low of $26 to a high of $84 per pair, mostly depending on the options I picked for lenses. If I had to come up with any criticisms, the only (very) minor issue I had was one pair’s lenses (with identical prescriptions on both sides) were cut slightly different, so that when the light hits them, you can see a bit more of border on one lens over the other (like I said, it’s minor). I purchased frames from four different companies mentioned on the GlassyEyes site and every pair showed up intact and the prescriptions all seemed identical.

I’ve had such good success with it that I recently ordered some higher priced specialized sports glasses online, saving about 35% over what an optometrist ofﬁce would charge. Overall, I couldn’t be happier with the process of buying glasses online. I’m happy to have several backup pairs and different styles to ﬁt my mood. About the only drawback is that there is almost too much selection online. Picking out each frame took me about an hour, after wading through 150-200 results and checking measurements on the ones that caught my eye.

I encourage anyone looking to save some money and get a bigger selection to search online. Glasses are no longer a scarce resource costing many hundreds of dollars, they can be as simple as buying a DVD or book online, and cost about the same.

Vox Pop: Re-creating scarcity

Merlin — Thu, 27 Sep 2007 11:43:07 -0400

I have a friend who told me he was thinking about giving his project managers a weekly pile of chips that could be redeemed for person-hours in meetings. So, to schedule ﬁrewalled, group face-time, the PM would need to cough up the equivalent number of tokens from her pile. Thus, one, long, all-hands meeting might require the whole week’s stack. While, fewer, shorter meetings with smaller groups made the pile go further.

It was just an idea, and I’m pretty sure he never implemented it, but I think it’s a fascinating concept. Why? Because I love the idea of re-introducing scarcity into systems that lack boundaries.

Think how the internet in particular (for better and worse) is working to erase any sense of scarcity in our lives – at least in terms of access to people and ideas. You can email anybody any time; you can divebomb onto someone’s radar screen with an IM or SMS; you can have Amazon deliver almost anything to your door tomorrow morning; you can ﬁnd and download from millions of ﬁles instantly; and, given the right tool, you can locate almost any fact in seconds.

But what about the very real (and truly limited) resources that involve human time and attention? Do we want to make ourselves as available as Google and Wikipedia are? Do we want our entire staff to be “always on” for anyone who wants them? What if, for example, emails to a distribution list cost something?

The Question to You

Have you thought about ways to re-introduce scarcity into your life and work? Are you or your team using any homemade systems to govern resources that might otherwise become overtaxed or abused? How would you solve the “too many long meetings” problem?

If life were like YouTube

Merlin — Fri, 21 Sep 2007 19:00:33 -0400

Ok, it’s Friday, and the team and me are pooped from several weeks of site-making. No profound tips today. I’ll just leave you to your weekend with a wonderfully timely video.

I’ll confess that the escalating assiness of internet comments was a huge factor in deciding to move to a membership-based site (yeah, I know it’s no panacea, but it sure doesn’t hurt). Said assiness is illustrated beautifully in this video, portraying a world where life is like a YouTube comment thread. Awesome (if very NSFW). Have a great weekend. Pwnd!
