[Boston.pm] Image problem?

[Shirley Márquez Dúlcey]

We may have a bit of an image problem. Perl was the #1 most disliked
language in a recent poll on Stack Overflow. Surprisingly, Delphi was
#2; I didn't think it was known and used widely enough to score that
high on the list.

Aside from simply looking out the window, or watching or listening to
one of the dire weather reports, there is also the fact that MIT is
closed for the day. When that happens all room reservations are
cancelled.

Re: [Boston.pm] perl 5.10 memory leak?

[Shirley Márquez Dúlcey]

Is there a reason why you have to use 5.10.1? Upgrading isn't an option?

Re: [Boston.pm] december meeting preview : Hadoop with Perl !

[Shirley Márquez Dúlcey]

The 350 was originally a semi-express bus that ran to Haymarket. It
had a small number of stops up to Arlington Center and was a local
after that. You paid a zoned express bus fare to ride it; how much you
paid depended on how far out of the city you were going. When Alewife
Station opened the 350 route changed to its current configuration of
ending at Alewife, and it became a normal fare route.

There are many other high numbered bus routes that are not express
buses. The numbers signify the area they serve. Routes under 100 are
in Boston, Cambridge, and other nearby places. The 100s serve northern
suburbs: Malden, Melrose, Winchester, Reading. 200s go to southern and
southeastern towns: Quincy, Braintree, Hingham. 300s go to northwest
suburbs: Bedford, Burlington, Woburn. 400s go northeast: Lynn, Salem,
Peabody. 500s go west: Waltham and Newton. The former MBTA route to
Wellesley is now privately run.

Many but not all of the 300, 400, and 500 series are express lines.
The 424 and 426 are unusual: the weekday versions are express buses
that run to Haymarket, but the weekend versions are normal fare buses
that end at Wonderland, where you can get on the Blue Line to go the
rest of the way into the city.

There are some privately run but MBTA-subsidized routes with numbers
in the 700s. They have the quirk that they accept passes but only if
they are printed on Charlie Tickets rather than encoded on Charlie
Cards, and do not accept stored value Charlie Tickets or Cards.

What happened to the southwest (Dedham, etc.)? The few that exist are
in the under-100 group. There are also MBTA commuter rail trains.
Privately run buses, notably the BAT (Brockton Area Transit), serve
that area as well.

 The 350 bus seems to go up that way too, following Cambridge Street from
 Arlington. You catch it upstairs at Alewife, at the end closest to the
 bike path where the bus to NYC used to leave from.  Despite the high
 number, it's a normal fare bus (probably since there's nothing express
 about it).

 Next meeting
 December 9TOPIC: *Stirring the Hive with a Perl Stick*
 SPEAKER: *Charles Hardin*
 DATE: December 9, 2014
 LOCATION: EIG Offices, Burlington.
 Address - To be verified - 10 Corporate Dr #300, Burlington, MA 01803
 TIME: Usual 7-9:30 (unless corrected)

 ABSTRACT
 Hive provides a SQL-like interface to Hadoop. Perl can interoperate with
 Hive in a variety of ways, including Hive queries through a Thrift API and
 the direct incorporation of Perl into map-reduce jobs. The author has taken
 a few baby steps on this journey and chooses to share the results with his
 peers.

 KEYWORDS: Perl, Hadoop, Hive, Big Data, Thrift, Map-Reduce.

 This meeting is being hosted by EIG, Sean and Charles's employer, in both
 senses of 'hosted'. This is a one-off experiment - i feel strongly about
 having a balance of public transport access and easy parking; E51 is good
 on both. So a carpool from MIT and/or Red Line will be available for
 Car-Free commuters, talk to Bill bill.n1...@gmail.com off-list.

 (ROOM E51-37*6* wll be cancelled for this month, see above. If I'm really
 really nice i'll leave a sign there ...)

Re: [Boston.pm] OT: DSL recommendations?

[Shirley Márquez Dúlcey]

Megapath still offers DSL, though they're only marketing actively to
business customers these days. But you're at the mercy of Verizon for
the copper, and my recent experience is that it is a major problem.

 Are you literally looking for a DSL provider, or did you mean an
 Internet provider?

 I believe MegaPath (formerly Covad) still sells DSL to new customers in
 the Boston area.

 BLU's Discuss list (http://www.blu.org/) is a better list to ask about
 this. The topic comes up there periodically, and you can probably find a
 bunch of threads in the archives:

 In my book, Verizon is pretty terrible.
 Comcast, on the other hand, seems like a better company.

 The quality of the customer service at these big consumer companies
 operating in monopoly or near monopoly markets probably ebbs and flows
 over the years, but usually they earn the bad reputations they have.

 Similar to your experience, a colleague moved recently and was looking
 forward to getting FIOS at the new location. He called Verizon to
 schedule the install. They didn't give him an ETA. Days went by, and
 still they couldn't tell him when the install would happen. (It seems
 there was confusion on Verizon's part as to whether the apartment was
 wired for FIOS already.) In contrast, he called Comcast, they confirmed
 the apartment was wired for it, and a day layer had network service working.

 On the other hand, I've been a long time Comcast customer for video
 service, and I resent that I need to call in yearly to renegotiate my
 bill in order to get a sane rate. (If you're not currently paying a
 promotional rate for cable TV, you're likely paying way more than you
 could be.) But Comcast isn't alone in jacking up prices and adopting
 limited time promotional rates, they're just a happy participant in this
 ugly approach. They seem to be trying to price their product to
 encourage cord cutting. At least until you notice the high prices and
 threaten to cancel. Then they practically give it away so they don't
 have to show declining video subscriber numbers to their shareholders.
 (This is why you can often get Internet + video for less than Internet
 only.)

 You can usually get a better customer service experience from these
 companies by paying a bit of a premium for business class service. It'll
 also lets you bypass stupid restrictions, like port blocking, data caps,
 and policies that prohibit servers.

 My understanding is that Verizon has a superior last mile architecture,
 yet Comcast's engineering group seems to put them among the most
 advanced ISPs, with early adoption of DNSSEC and IPv6. (If Comcast
 upgraded to dedicated fiber loops to the premise, and ran their customer
 service and policy side of their business the way they run engineering,
 they'd be a potentially terrific ISP.)

Re: [Boston.pm] C++ books

[Shirley Márquez Dúlcey]

 I would highly recommend 'The Design and Evolution of C++' by Stroustrup.
 It's an older book now, but still was written with a great deal of
 perspective on the use of C++ and does a good job of explaining why many
 things are the way they are -- which of those things are for the best and
 which are not.

In my opinion, Stroustrup's book is a must-read for anybody interested
in computer language design. It's a shining example of something that
has rarely been attempted: explaining WHY a language works the way it
does. You may come out of reading it with a new appreciation of C++ or
with a new hatred of his boneheaded design priorities (or perhaps some
of each as I did), but either way you will know a lot more about the
kinds of tradeoffs one must make when designing a language.

If you just want to learn to program in C++, Stroustrup may not be the
best use of your time.

Re: [Boston.pm] emergency social - tues 7pm, sunset grill and tap

 From a hotel near Faneuil Hall to Sunset in Allston, I'd say just take a cab.

There isn't really a train that goes quite the right way. You can take the 
Green Line (B branch?) and have a pretty long walk up 
less-sketchy-than-it-looks Harvard Ave, or the bus which won't necessarily be 
any faster, but at least would be a shorter walk.

(Nb. this is coming from a car driver. I like the *idea* of taking public 
transportation around Boston, but the network isn't quite fleshed out like it 
should be ― all spokes, no hubs ― so in practice a lot of routes like this are 
more complicated than they should be. Others may have a higher tolerance for 
this and just suggest taking a bus anyway.)



The walk up Harvard Ave is actually only five minutes, and really not 
scary at all. The walk at the other end is longer (8 minutes) and on the 
return trip would actually be more scary to me, as the downtown area 
gets rather deserted late at night.


Google Maps offers various estimates ranging from 37 to 49 minutes for 
the trip by T (I used a departure time of 6pm Tuesday). Surprisingly, 
the one where you stay on the train is the longest one -- not because of 
the 5 minute walk at the end (the time changing from the train to the 
bus balances that out) but because they believe that the B train 
progresses more slowly than the 57 or 57A bus.


Google Maps gives a driving time of 13-14 minutes at the same hour. 
Based on my knowledge of Boston traffic I suspect that estimate is 
wildly optimistic; I would expect it to be double that, plus the time 
spend finding a parking space near the Sunset.
