Best public DNS – finding the best for you

If your Internet connection is slow, it almost always helps if you optimize your DNS. But there’s more to the best public DNS than just speed. I’ll tell you how to find the fastest DNS, but using a DNS that offers improved security gives your computer protection beyond what your antivirus and firewall provide.

Sometimes it’s enough, and it’s definitely cheaper than buying a new router. Even if you do get a new router, using fast DNS helps. Here’s how to find the best public DNS to use, to improve your speed and your security.

Review: D-Link DSL-2640B

Dave Farquhar Hardware, Servers and Networking , , , , ,

I’ve had DSL for right around 10 years. I would have ordered it sooner, except it wasn’t available in my area any earlier than that.

Over the years I’ve owned several modems. I started out with an Alcatel, then after I moved a mile down the street I owned a couple of different Speedstream modems. Each would drop connections every so often, and each had a different (and undocumented, of course) ritual to get it back online.

The highest praise I can give to the D-Link DSL-2640B is that I haven’t discovered such a ritual yet. If the phone line and electricity are working, it finds a way to stay online.

There’s nothing especially flashy about the 2640B. It’s an unassuming black and silver box, similar in styling to modern PCs, with jacks in the back. It’s a combination modem, gateway, and switch in one package, so in my case, it replaced two boxes–my Speedstream modem, and my Linksys WRT54G. Many ISPs have been distributing all-in-one units made by companies like 2wire in recent years; the D-Link is similar to those, but a bit smaller than many of them.

Setup is trivial for someone who’s set up devices like my old Linksys. Those who’ve never done such a thing may need assistance. I can’t vouch for the quality of D-Link’s customer service because I didn’t need it. Before I plugged the unit into my phone line, I plugged a laptop into the D-Link, brought the two units over to my desktop PC where I brought up my Linksys configuration, and I checked all my settings against the Linksys. About 10 minutes later, I plugged the D-Link into my phone line, it connected to my ISP, and it’s been online ever since.

The nicest feature is its ADSL information screen. It tells me the modem speed (downstream and upstream), number of errors, and other diagnostic information. I’ve seen my speed range from 1.5 megabit to as low as 256K (upstream stays steady at 384K), but it’s never dropped. I’ll take speed fluctuations over dropped connections any day. If the quality of my phone line deteriorates any further (or maybe I should say, “when”)–I’ll be armed with some good information. Southwestern Bell/SBC/AT&T have always been able to dismiss my complaints in the past. I imagine that’ll be harder to do when I can tell them exactly how many tens of millions of downstream errors I have, versus 96 upstream errors.

Despite those connections, the modem keeps on trucking. I’m impressed.

My sole complaint is that the DynDNS client doesn’t pass my domain name to my internal network. I had to put an entry for my DynDNS name into my hosts file. This won’t be an issue for anyone who isn’t running their own web server, but it’s a little aggravating for those who do. Less aggravating than a dropped connection though.

So if you need a new DSL modem for whatever reason, I recommend the D-Link DSL-2640B. It isn’t flashy, but it works and keeps working.

Update 10 October 2010: I’ve been using this unit for about 15 months, and it’s still going strong. So I can recommend it even more strongly than when I wrote this. It’s out of warranty now, and I didn’t even notice.

The Western Electric 500

Dave Farquhar General , , , , , , ,

Another year, another cordless telephone/answering machine.

I bought a cordless phone to replace an aging and failing 2.4 GHz model this week. Our luck with modern phones makes me long for the old days.

western electric rotary phone model 500
The Western Electric model 500 rotary phone is as indestructible and reliable as it is iconic.

I like the old Western Electric 500 (also known simply as “The Bell Phone”) because it was specifically designed not to break.We own three. My wife and I both have a habit of picking them up when we see them cheaply at garage and estate sales. I see at least five a year, but I only buy if it’s cheap. Maybe there’s some book somewhere that says a Model 500 in a common color is worth $20, but I won’t pay that much for one.

They’re annoying to use for dialing, of course, since they’re strictly old-school pulse. But we can use the cordless phone when we need to dial, or the green Southwestern Bell Freedom Phone I bought for my first apartment, which somehow still works after 10 years.

When it comes to just answering the phone and talking on it, they’re just like any other corded phone, except the handset is a bit heavier.

The other annoying thing is that they don’t ring, but tonight I found a cure for that. Opening the phone up and moving one wire usually cures that problem. (Follow the link and scroll to the last section of the page.)

How reliable are they?

Well, tonight I opened up the one I keep in my office to rewire the ringer, and I found it was made in 1957. After 51 years, it’s still going strong.

We have one in the bedroom too. It’s a later model, made by Stromberg Carlson under license, dated September 1978. Although it looks just like a Western Electric, it feels a little bit lighter and less rugged to me. Nevertheless, after 30 years it still works fine.

Those are really good track records, in an age when we tend to think of things as nearly indestructible if they manage to last five years.

And I’ll admit I like the retro look they have about them. Although I’m not old enough to remember the days when it was illegal to plug anything not made by AT&T or a subsidiary into your phone jack, these are the phones pretty much everyone had up until 1984, when the government temporarily broke AT&T up. My parents and grandparents used these phones. And when my house was built in the mid 1960s, it was almost undoubtedly equipped with a 500 too, and I’d be willing to bet that 500 served as its primary phone well into the 1980s.

I wouldn’t want to trade everything in my house for 1949 technology, but just like my old IBM Model M keyboards, I definitely have a thing for those heavy old-fashioned phones.

What net neutrality means and why it\’s a good thing

Dave Farquhar net.culture , , , , , , , ,

This week, John C. Dvorak makes a good argument in favor of net neutrality.

I’m going to take it from a different angle. I am a conservative. While I rarely vote a straight Republican ticket, I am registered as a Republican. Republicans generally are against net neutrality.

They are wrong. I will assume it’s from a lack of understanding rather than bad intentions, but in this case, wrong is wrong. I’ll explain why. Read more

Net neutrality has little to do with censorship but it\’s a good idea anyway

Dave Farquhar net.culture , , , , ,

Pearl Jam came out in favor of net neutrality after AT&T censored a broadcast a performance they did in Chicago last Sunday. I guess AT&T didn’t like Pearl Jam’s anti-Bush message.

I don’t know if Pearl Jam’s sudden embrace of net neutrality is out of ignorance, or if it’s retaliation. It doesn’t really matter because it should help bring some more awareness to the issue.Here’s the issue with net neutrality, in a nutshell. AT&T wants to charge companies like Amazon, eBay, and Google when people like you and me access their web pages. And if the companies don’t pay, AT&T will make the web sites slower. The idea is that if one company doesn’t pay the fees but a competitor does, AT&T customers will probably opt to use the faster services.

Proponents say AT&T built the infrastructure, so they have the right to charge whoever uses it.

There are two problems with that logic.

They’re already paying to use it.

When a company decides to go online, they buy an Internet connection. That connection might be owned by AT&T, or it might be owned by some other provider. It isn’t cheap. While a 1.5-megabit cable modem connection might cost a consumer $30, a commercial-grade 1.5-megabit T1 connection will cost more on the order of $500 a month. A company like Google needs a lot more than one of these connections. Google most likely is spending hundreds of thousands of dollars, if not millions, every month for the privilege of being on the Internet.

Without content, an Internet connection has no value.

AT&T knows nothing about how online services work, because they haven’t been in the business long. Twenty years ago, if you wanted to go online, you didn’t use the Internet unless you were a college student. You subscribed to a service like AOL or Compuserve or Prodigy, who sent you a disk and a local phone number that you called with your modem, and then when you wanted to go online, you connected to their service. It had e-mail and forums and downloads and news, kind of like the Internet does today, but it was smaller. You could interact with other subscribers but that was pretty much it. E-mail was limited, for the most part, to other members of the same service.

Compuserve was the biggest and most expensive service, but it survived because it had the most features. AOL and Prodigy survived because they were easy to use. GEnie, a competing service operated by General Electric, survived primarily because it was cheaper than the others. Each had a niche. In these cases, the company providing access also provided the content. It was a closed system.

The Internet is an open system. AT&T isn’t providing all of the content. AT&T is my Internet provider, and I never touch any of their content, except when my credit card expires and I get a new one and I have to go to att.com to update my account with the new expiration date for my automatic bill-pay.

If it weren’t for the companies like eBay and Amazon and Google, nobody would want an Internet connection in the first place, because without those providers, an Internet connection is pretty much useless. The only reason the Internet took off in the first place was because companies like AOL and CompuServe couldn’t offer services that were as good as what Google and Amazon and eBay.

That’s why AOL went from a blue-chip stock to a drag on Time-Warner’s share price in less than a decade.

People buy Internet connections so they can use Google and Amazon and eBay. Very few people care about the mostly sterile content AT&T puts on the Internet. I’m sure some people enjoy watching concerts in the AT&T blue room, but I’ve never heard of anyone watching anything there. But I hear every day about what someone bought or sold on eBay, or a story that showed up on Google News or CNN.com, or a book someone bought on Amazon.

And when they use e-mail, people increasingly are using e-mail from Google or Yahoo or Microsoft instead of the one from their Internet provider. That way they can read their mail anywhere, and they can keep their e-mail address even if they move or change Internet providers. So Internet providers aren’t even the primary source of the most basic services anymore.

If anything, AT&T should be paying the companies that produce the content. Not the other way around.

AT&T isn’t selling content. It’s selling a pipe that content travels to. Lest AT&T get a big head, all AT&T has to offer is plumbing.

So what does this have to do with censorship?

Net neutrality has very little to do with censorship. I suppose someone with contrarian views operating a blog on a shoestring who can’t afford to pay for both an Internet connection and the privilege of running in AT&T’s fast lane is a victim of a form of censorship. Or if Google doesn’t pay to be in the fast lane but Yahoo does, then in a way Google is being censored in favor of Yahoo.

But if AT&T chooses to drop the audio out of a Pearl Jam concert, net neutrality isn’t going to stop that. In that case, AT&T is the provider, not just the company providing the plumbing.

But net neutrality is a good thing because without it, what’s going to happen is higher prices for the things you buy on Amazon and eBay, and less content on news sites because the news providers can’t afford as many writers because now they’re having to pay AT&T and every other company that sells digital plumbing. You get less, so that Randall Stephenson gets a higher salary and a more attractive stock options.

Stephenson made $14.6 million last year, before he got promoted to CEO.

I don’t think you and I need to make any more sacrifices in order to give this fat cat a bigger raise.

Western Electric rotary phone tips and tricks

Western Electric rotary phone tips and tricks

I heard on the radio this morning about an 82-year-old who up until two months ago was still paying AT&T $29.10 a month to lease an old Western Electric rotary phone.

Those old Western Electric rotary phones are good. But they aren’t worth $29.10 a month in rental fees.

In honor of Southwestern Bell and AT&T getting back together

Dave Farquhar Saving money , ,

In honor of Southwestern Bell and AT&T getting back together, here’s how to do your own phone wiring.

Go get ’em, SCO!

Dave Farquhar Windows , , , , , , , , , ,

I’m sure you’ve read it 4.3 billion other places already, but Microsoft has been granted a patent on double-clicking.

Well, there’s something you probably have only read a few hundred other places. Apple obviously had people double-clicking more than a year before Microsoft did, seeing as Windows 1.0 was released in November 1985 and the first Macintosh shipped in early 1984. Commodore had Amigans double-clicking by the summer of 1985. So did Atari.

Guess who supplied Atari with its operating system, since Jack Tramiel failed to swindle his way into ownership of the Amiga?

Digital Research, that’s who. DR provided Atari with a version of CP/M-68K, with its GEM GUI running on top of it. Atari marketed the bundle as TOS, for Tramiel OS.

Digital Research got crushed by the Microsoft juggernaut a few years later and eventually sold out to Novell. Novell then attempted to compete head-on with Microsoft (buying up its Utah neighbor, WordPerfect, and part of Borland in the process) and failed spectacularly. Smelling a rat–Novell believed Microsoft sabotaged some of its applications so they would not run under DR-DOS–it then pawned the Digital Research portfolio off on Caldera, a Linux company run by former Novell executives. The catch? Caldera had to turn around and sue Microsoft. Which they did, successfully.

A few more years later, The Santa Cruz Operation, a small Unix firm, wanted out. It sold its Unix-on-Intel business, as well as the rights to the old AT&T Unix (purchased from Novell, ironically) to Caldera, who soon changed its name to The SCO Group to reflect this business.

Yes, this is the same SCO who is now on a legal rampage, suing anything that moves.

Now, whether Novell or SCO is the more rightful owner of the double-click “innovation” is arguable. But such matters never seem to matter to SCO. It’s a frivolous lawsuit, but Darl McBride and Co. have made frivolous and baseless lawsuits into an art form.

Go get ’em, Darl.

Heading back to Way Back When for a day

Dave Farquhar Personal , , , , , , , , , , , ,

Someone I know house-sat this weekend for a couple who are slightly older than my parents. Their youngest daughter, from what I could tell, is about my age, and they have two older daughters. All are out of the house.
It was like walking into a time warp in a lot of ways. There’s an old Zenith console TV in the living room. My aunt and uncle had one very similar to it when I was in grade school, and it spent several years in the basement after it lost its job in the family room. First there was an Atari 2600 connected to it, and later a Nintendo Entertainment System. My cousin and I used to spend hours playing Pole Position and Mike Tyson’s Punch-Out and various baseball games down there.

The living room housed a modern JVC TV, armed with a modern Sony DVD player and RCA VCR. But in the other corner was a stereo. The Radio Shack Special 8-track player was the stereotypical 1970s/early 1980s brushed metal look, as was the graphic equalizer. The tuner was also a Radio Shack special, styled in that mid-1980s wanna-be futuristic style. If you lived through that time period, you probably know what I’m talking about. But if you’re much younger than me, you’re probably shrugging your shoulders. Beneath it was a Panasonic single-disc CD player in that same style, and a Pioneer dual tape deck. A very nice pair of Fisher speakers finished it off. It was definitely a setup that would have turned heads 17 years ago. (I have to wonder if the Fishers might not have been added later.)

It seems like there are only two genres of music capable of being emitted by an 8-track player. Once genre includes Led Zeppelin and Rush. The other includes John Denver, Rod Stewart, Barry Manilow and The Carpenters. Their collection was on the latter side, which sent my curiosity scurrying off elsewhere.

But I had to try out that stereo. I kind of like The Carpenters, but I have to be in the mood for them, and I’ve heard enough John Denver and Rod Stewart and Barry Manilow to last me forever. So I checked out the CDs. Their CD collection was an interesting mix, but with a good selection of contemporary Christian (albeit mostly pretty conservative contemporary Christian). I popped in a CD from Big Tent Revival. I don’t remember the title, but the disc was from 1995 and featured the song “Two Sets of Joneses,” which I still hear occasionally on contemporary Christian radio today.

About three measures into the disc, I understood why they hadn’t replaced that setup with something newer. It blew my mind. I heard a stereo that sounded like that once. In 1983, we moved to Farmington, Mo., which was at the time a small town of probably around 6,000. We lived on one side of the street. Our neighbor across the street owned the other side of the street. Any of you who’ve lived in small midwestern towns know what I mean when I say he owned the town.

Well, in addition to owning the biggest restaurant and catering business and tool rental business in town and a gas station, he also owned a mind-blowing stereo system. Hearing this one took me back.

I almost said they don’t make them like that anymore. Actually they do still make stereo equipment like that, and it costs every bit as much today as it cost in 1985.

And Big Tent Revival sounded good. If I’m ever out and see that disc, it’s mine.

Upstairs in one of the bedrooms, I spied a bookshelf. It was stocked with books of Peanuts cartoons, but also tons and tons of books I remember reading in grade school. Books by the likes of Beverly Cleary and Judy Blume, and books by other people that I remember reading 15 or even 20 years ago. The only things I didn’t remember seeing were S.E. Hinton and Paul Zindel, but as I recall, those books hit me so hard at such a period in my life that I didn’t leave those books at home. Or maybe Hinton and Zindel were a guy thing. I’m not sure. But seeing some of the names that made me want to be a writer, and being reminded of some of the others, well, it really took me back.

Next to that bookshelf was a lamp. Normally there’s nothing special about a lamp, but this lamp was made from a phone. This reminded me of my dad, because Dad went through a phase in life where there were exactly two kinds of things in this world: Things you could make a lamp from, and things you couldn’t make a lamp from. Well, this was a standard-issue wall-mount rotary phone from the pre-breakup AT&T Monopoly days. One just like it hung in my aunt and uncle’s kitchen well into the 1980s.

The computer was modern; a Gateway Pentium 4 running Windows Me. It desperately needed optimizing, as my Celeron-400 running Win98 runs circles around it. Note to self: The people who think Optimizing Windows was unnecessary have never seriously used a computer. But I behaved.

I don’t even know why I’m writing about this stuff. I just thought it was so cool.

But I remember long ago I wrote a column in my student newspaper (I’d link to it but it’s not in the Wayback Machine), which was titled simply “Retro-Inactive.” Basically it blasted retro night, calling it something that people use to evoke their past because their present is too miserable to be bearable.

Then I considered the present. Then I thought about the 1980s. We had problems in the 1980s, but they were all overshadowed by one big one–the Soviet Union–that kept most of us from even noticing the others. We had one big problem and by George, we solved it.

So I conceded that given the choice between living in the ’90s or living in the ’80s, well, the ’80s sure were a nice place to visit. Just don’t expect me to live there.

I’m sure people older than me have similar feelings about the ’70s, the ’60s, the ’50s, and every other previous decade.

And I guess I was just due for a visit.

My what-I-did-tonight piece

Dave Farquhar Personal , , , , , , , , ,

I hate to do a boring this-is-what-I-did-tonight post, but I figure the occasional one of those is better than silence from my direction.
I’m sick again. I think this is some kind of record. This pattern of five-day breaks between illnesses really better not last much longer.

So I went out to stock up on sick supplies. You know the drill: chicken soup, zinc lozenges, vitamins. I went in to get my vitamins, then found myself blocked in, so I continued down the aisle and found the first vacant aisle to cut through. Of course it was the make-up section. I felt especially manly cutting through the make-up section, especially considering my next stop was… the sewing section. I needed a needle and thread, for two reasons. I’ve got two shirts with buttons popped off, and I learned a cool way to bind books, but you need a drill (which I have) and a needle and thread (which I didn’t) in order to do it.

So I picked up a couple different colors of thread, then wandered aimlessly for a while until I stumbled across the needles. I found a 25-pack for 64 cents. Good deal.

I really, really hope I looked as lost as I felt.

So when I got home I bound a short book. The idea is this: You drill holes a quarter inch from the top and the bottom, then drill two more holes spaced two inches apart. Cut a length of thread about four times as long as the book is high. You can get the sewing technique from this PDF file. Traditionally, you use Japanese stab binding for short books of drawings, poetry, or journals. But I found it works just fine for everyday stuff. I recently printed a few public domain texts from Project Gutenberg, and this provides me with an easy and extremely cheap way to bind them.

I was trying unsuccessfully to sew on a button when my phone rang. It was my girlfriend. She asked what I was doing. I told her I was making a fool of myself trying to remember how to sew on a button. She described a technique to me, and when I got off the phone with her, I gave it another try. I think I ended up using a combination of her technique and my mom’s, but it worked. The button’s not going anywhere.

Something she said gave me my masculinity back. She asked how I was at threading needles. I said I had some trouble doing it. She said part of the reason sewing is traditionally a women’s thing is because women have smaller hands, which are more adept to the fine movements that sewing requires. My hands aren’t huge, but they’re bigger than most women’s. She said threading a needle requires good vision, concentration, and a steady hand. I’ve got good vision and concentration. But every time I tried to do something that required a steady hand, my dad just shook his head and said, “You’ll never be a surgeon.” And they’ve only gotten worse with age.

And before all this, I spent some time writing up a piece talking about all the lovely things Microsoft did to DR DOS in the late 1980s. This is in response to some mudslinging that happened over at my recent anti-Microsoft piece. Normally I’d just ignore a troll who doesn’t even have enough guts to put his name on his taunts–all I know about him is his IP address is 12.209.152.69, which tells me he’s using a cable modem attached to AT&T’s network, he lives in or around Salt Lake City, Utah, and at this moment he’s not online–but I think this story needs to be told anyway. Depth is good. Sources are good. And there’s a wealth of information in the legal filings from Caldera. And those filings prove that my memory of these events–I remember reading about the dirty tricks in the early 1990s on local St. Louis BBSs–was pretty accurate.

I’m not surprised. I have a knack for remembering this stuff, and I had occasion to meet an awful lot of really knowledgeable people back then.

If I can still remember that Commodore’s single-sided 170K 5.25″ drive was the 1541, its double-sided 340K drive was the 1571, and its 800K 3.5″ drive was the 1581 and I remember the command to make the 1571 emulate the 1541, and why you would want to emulate a 1541, I can probably just as easily remember what you had to do to get Windows 3.1 running under DR DOS and what the reasons were for jumping through those hoops. That history is more recent, and at this stage in my life, I’m a lot more likely to have occasion to use it.

Not that I’m trying to brag. I can remember the names of the DR DOS system files, and I can remember George Brett’s batting average in 1983, but at the end of a five-minute conversation with someone I just met, I’ll probably struggle to remember a name. Or if you send me to the store, you’d better give me a list, because I’m good at forgetting that kind of stuff.

I suspect the DR DOS piece is half done. I might just get it posted this week.
