Ivolga (train). The Ivolga (named after "Иволга" bird, e.g. Eurasian golden oriole), designation EG2Tv and EGE2Tv, is an electric multiple unit passenger train produced and manufactured by Tver Carriage Works (TVZ) for urban and commuter service.

History

The exterior and interior styling, however, was outsourced: TVZ ordered the design of the concept train to Integral Design and Development (Arina Design) (Barcelona, Spain). A natural scale mock-up was built by Integral Design and Development and presented in Russia in 2015.

Re-styling of Ivolga was also outsourced to Integral Design and Development (Arina Design) in 2017. First Ivolga 2.0 trainset was built in 2019.

Since November 2019, an upgraded Ivolga 1.0 trains have been serving Line D1 of Moscow Central Diameters.

In 2021, yet another iteration of the design was presented, EGE2Tv, named Ivolga 3.0, with increased to 160 km/h max speed and meant for traveling longer distances. Whilst still utilizing the 2.0 exterior, the interior was updated by the Russian 2050.lab studio. They were meant for the D3 line of Moscow's MCD system planned opened in August 2023. The first trainset was completed in 2022.

The next modification, Ivolga 4.0, is an urban variant with 3 doors per middle car. A trainset with eleven cars has 646 seats. The first trainset was built in 2023.

Overall 41 EG2Tv and 34 EGE2Tv trains have been produced by June 2024, working on lines D1, D2 and D4 of MCD Moscow's metro-rail (high-capacity urban-rail) system as well as on express route Moscow – Usovo.

Macchi M.C.77. The Macchi M.C.77 was a reconnaissance bomber flying boat built by Macchi in the thirties and remained at the prototype stage.

Development and design
In 1933 the Ministry of Aeronautics issued a specification for the supply of a new reconnaissance and bombing seaplane to be allocated to the Departments of the Regia Aeronautica with the intent of replacing the Savoia-Marchetti S.78 in service since 1932. The CRDA CANT, aeronautical division of the Cantieri Riuniti of the Adriatic and later also the Aeronautica Macchi participated in the competition announcement.

The Macchi M.C.77 was characterized by the central hull configuration with a single step and side floats, high-cantilever monoplane with cantilever, equipped with a motor in a pushing configuration positioned above the hull on a tubular castle. The structure was of mixed type with metal fuselage having the war load stowed inside on one side and the other.

The project was presented to the Regia Aeronautica in 1934, to build the prototype already started, when the rival CANT Z.501 had already flown. The Air Force Genie, however, deemed the project interesting, but significant delays accumulated so that the prototype was only completed in 1935 and was not yet ready for the acceptance tests that were to take place in Nisida in August 1936. At this point, the Regia Aeronautica chose the Z.501 as the replacement for the S.78.

The Macchi also built a scale model that presented to the public at the 1st Milan International Air Show in October 1935, but not getting feedback in the military aviation market decided to stop its development.

JDK Flight Recorder. JDK Flight Recorder is an event recorder built into the OpenJDK  Java virtual machine. It can be thought of as the software equivalent of a Data Flight Recorder (Black Box) in a commercial aircraft. It captures information about the JVM itself, and the application running in the JVM. There is a wide variety of data captured, for example method profiling, allocation profiling and garbage collection related events. The JDK Flight Recorder was designed to minimize the Observer Effect in the profiled system, and is meant to be always on in production systems. The technology was open sourced in 2018.

Analysis and visualization of flight recordings are normally done using JDK Mission Control.

Technology
A recording file consists of binary chunks of data. Each chunk is self describing and self contained. In other words, the metadata (such as the datatype and the content type of each attribute) needed to make use of the data (not only parse the events, but actually use them) is included in the chunk. Also all the values required to be resolved through e.g. constant pools are also included in the chunk.

There is a wide variety of technologies employed to make the JFR efficient, for example:
 Binary representations, no translations back and forth to strings, the buffers are efficiently emitted to disk
 Most events are recorded into thread local native buffers
 On some platforms invariant TSC is employed for efficient time stamping
 Integer compression scheme, to keep in-memory and on-file size down
 Since implemented in the JVM, much data is readily available, or emitted at a time when the data is readily available, keeping cost down

If converting a binary recording to JSON, it can easily blow up by two orders of magnitude or more, depending on length and content recorded.

The expected performance overhead of JFR using the default template is less than a percent, and for the profiling template, less than two percent.

History
JDK Flight Recorder started out as JRockit Flight Recorder, and was originally used as a means to collect data to be used to improve the JVM itself. After Oracle acquired Sun Microsystems, JRockit Flight Recorder was rebranded Java Flight Recorder. In 2018 Java Flight Recorder was open sourced and released as part of OpenJDK 11. When open sourced it was rebranded JDK Flight Recorder, due to Java trademark issues.

Versions
These are the versions of JFR file format available. It does not encompass all the versions that have ever existed, but rather versions that exist in JVMs after the migration to HotSpot.

Development
The development of JDK Flight Recorder is taking place as part of the OpenJDK JDK  project on GitHub, although most of the public discussions are taking place on the OpenJDK hotspot-jfr-dev  mailing list.

John Armstrong (engineer). John Armstrong (13 October 1775 – 17 March 1854) was a British civil engineer who worked on a number of canals, bridges and tunnels, mostly in Bristol and London. From 1831 to 1854 he was the City Surveyor for Bristol.

Career

Armstrong was born in Ingram, Northumberland and, after receiving little formal education, became a millwright's apprentice in Bill Quay. In 1800 he moved to Bath and worked on several projects in the area, including the repairs to Pulteney Bridge and the construction of Bristol Harbour and Westgate Bridge.
From 1821 he worked on projects in London and South East England such as Rochester Bridge and Grosvenor Canal.
He was briefly the resident engineer for Marc Isambard Brunel's Thames Tunnel project but resigned due to poor health in August 1826, to be replaced by Isambard Kingdom Brunel.
After his resignation he worked for Bramah and Co at St Katherine Docks and managing property development. He joined the Institution of Civil Engineers on 11 March 1828.
In 1831 he became Bristol City Surveyor, a position he held until his death on 17 March 1854.

United Operative Spindle and Flyer Makers' Trade and Friendly Society. The United Operative Spindle and Flyer Makers' Trade and Friendly Society was a trade union representing workers involved in making textile machinery in the United Kingdom.

The union was founded in 1856.  In 1860, it applied to merge into the Amalgamated Society of Engineers (ASE), but it was rejected, as the ASE believed that its members were insufficiently highly skilled.  The union continued independently, and by 1900 it reached its peak membership, of about 1,300 members.

From a newspaper clipping: 
"The death of Mr James Agnew (7 January 1956), of 12 Dunn Street, Belfast, has also caused the death of a trade union in Ireland. For 85 year old Mr Agnew was the last surviving member in Ireland of the United Operative Spindle and Flyer Makers' Trade and Friendly Society. The Society at one time had hundreds of members all over Ireland. For many years Mr Agnew was regarded by the Society as being the Belfast branch for all official purposes, although he was retired. The annual report and balance sheet of the Society for 1954 show that in the Belfast branch - the only Irish one - contributions amounted to 4s. Remittances also amounted to 4s. The Society as still many members in Great Britain."

The rival Operative Mule and Ring Spindle Makers' Society is suspected by Arthur Marsh and Victoria Ryan of having merged into the Spindle and Flyer Makers at some point after 1925.  Despite this, its membership continued to fall, dropping to only 600 by the late 1940s, and under 200 in 1962.  That year, it finally merged into the successor of the ASE, the Amalgamated Engineering Union.
