đź’§ We All Hear a Yellow Multipurpose Machine

1 Comment

Planning for an extension of transit service north of Boston began all the way back in 1990, but it took more than two decades of planning and delays before the Green Line Extension finally broke ground in 2012. Though it’s likely difficult for residents to believe it, the project is now getting somewhat close to completion. Some of this construction is taking place relatively near me, and I receive occasional updates on it.

Last week, I was alerted to some night time work which will be done over the next several weeks. Here’s an excerpt from that email:

Somerville and Medford residents living near the GLX MBTA rail alignment— especially residents between Lowell Street and College Avenue—may experience elevated nighttime noise levels over the next few weeks.

“Elevated nighttime noise levels” certainly sound unpleasant, but I suppose to make an omelet, you need to break a few eggs. The email detailed the work to be done, and then explained:

The yellow Multipurpose Machine will be on the rails most nights to support this work and the vehicle is required to sound its horn when it stops and starts. Additional heavy machinery in the rail alignment is expected to produce elevated noise levels which may be disruptive at times. The scheduling of the work at night is because its completion requires at least one line of track to be out of service.

The emphasis in the above quote is added, and it bears repeating. In addition to all the noise which naturally accompanies the laying of new train track, a support vehicle used in this construction is required to sound its horn when it stops and starts. That sounds like it’ll be quite a night, or several weeks of nights. It also seems like adding real insult to injury for those living near this construction.

Fortunately for me, I don’t live near this construction, so I won’t be impacted. As a result, I’m most interested to know more about the “yellow Multipurpose Machine”. It’s capitalized as if it’s a proper noun, and yet at present, the only Google search results for it are from this exact press release.

Weekly Initial Unemployment Claims decrease to 3,169,000

1 Comment
The DOL reported:
In the week ending May 2, the advance figure for seasonally adjusted initial claims was 3,169,000, a decrease of 677,000 from the previous week's revised level. The previous week's level was revised up by 7,000 from 3,839,000 to 3,846,000. The 4-week moving average was 4,173,500, a decrease of 861,500 from the previous week's revised average. The previous week's average was revised up by 1,750 from 5,033,250 to 5,035,000.
emphasis added
The previous week was revised up.

The following graph shows the 4-week moving average of weekly claims since 1971.

The dashed line on the graph is the current 4-week average. The four-week average of weekly unemployment claims decreased to 4,173,500.

This was lower than the consensus forecast.

The second graph shows seasonally adjust continued claims since 1967 (lags initial by one week while increasing sharply).

At the worst of the Great Recession, continued claims peaked at 6.635 million, but then steadily declined.

Continued claims have already increased to a new record high of 22.647 million (SA) and will increase further over the next few weeks - and likely stay at that high level until the crisis abates.

Crazy numbers - note the continued unemployment claims: 22.6MM out of a workforce of 165MM. That is a minimum unemployment rate of 13%.

I’m worried about Joe Biden’s mental state. He denied this sexual assault claim, sure, but he completely forgot to call the woman a horseface, or say she wasn’t his type.

The story of a passenger who accidentally ejected from a fighter jet is amazing, and because everyone survived, it’s also hilarious.

March 24 Update: US COVID-19 Tests per Day #TestAndTrace

1 Share
Tests per day is a key number to track (along with actual cases and, sadly, deaths). But total tests were a key for South Korea slowing the spread of COVID-19. South Korea has been conducting 15,000 tests per day with a 51 million population, so the US needs to test around 100,000 per day.

Note: NYC and LA have stopped testing mild cases due to resource constraints. Hopefully testing will continue to improve, and we can test more people - this is important for test-and-trace.

The US conducted 63,851 tests in the last 24 hours.

Note: About 15% of tests were positive (red line, ht: NDD) in the most recent report (some are still pending). The high percentage of positives indicates limited testing.   For Test-and-trace to be effective, the percent positive would probably be at 5% or less.

This data is from the COVID Tracking Project. Some states could do a better job of reporting the number of tests - so this is probably low.

Testing is improving, but needs to double from here to be sufficient for test-and-trace.

Test. Test. Test. But protect our healthcare workers first!
