Chewang Norphel. Chewang Norphel  (born 1935) is an Indian civil engineer from Ladakh, who has built 15 artificial glaciers. He has earned the title of Ice Man.

Early life and career 
Coming from a middle-class family of Leh, Norphel went to Amar Singh College in Srinagar as a student of science. He completed a diploma course in civil engineering from Lucknow in 1960. In June 1960, he joined the rural development department of Jammu and Kashmir in Ladakh as a civil engineer. He retired in 1995.

Artificial glaciers 
In 1996, Norphel joined the Leh Nutrition Project, a non-governmental organisation, as project manager for watershed development.

Norphel noticed a small stream had frozen solid under the shade of a group of poplar trees, though it flowed freely elsewhere in his yard. He realized the reason for this phenomenon: the flowing water was moving too quickly to freeze, while the sluggish trickle of water beneath the trees was slow enough to freeze. Based on this, he created artificial glaciers by diverting a river into a valley, slowing the stream by constructing checks. The artificial glaciers increase the ground-water recharge, rejuvenating the spring and providing water for irrigation. He constructed them at lower elevations, so that they melt earlier, expanding the growing season.

By 2012, Norphel had built 12 artificial glaciers. Norphel's largest glacier is the one at the Phuktsey village. It is 1,000 ft long, 150 ft wide and 4 ft in depth. It can supply water for the entire village of 700 people and cost Rs 90,000 to make.

Documentary film-maker Aarti Shrivastava also directed a short film on his life titled White Knight, which was screened at film festivals in India and abroad.

Awards
He is a recipient of the Jamnalal Bajaj Award in 2010. He was awarded Padma Shri, the fourth highest civilian award of India, in 2015.

1541 Ultimate. 1541 Ultimate (often abbreviated 1541U) is a peripheral, primarily an emulated floppy disk and cartridge emulator based on the FPGA Xilinx XC3S250E, for the Commodore 64 home computer. It became available in 2008.

The unit is developed by Gideon Zweijtzer and is a cartridge that can emulate other cartridges such as the Commodore REU, Action Replay, The Final Cartridge III, Super Snapshot V5, Retro Replay or TurboAss with Codenet-support, and an almost fully compatible (including JiffyDOS support FPGA-cloned Commodore 1541 (including 1541, 1541C, and 1541 II models) floppy disk unit that can use Commodore 64-compatible files like .D64/.G64 disc images or .PRG files via a SD card reader. Additionally, the 1541 Ultimate is suitable for making archives of floppy disks. All units after the initial production have 32 megabytes of RAM, while the original production run only had 16 megabytes.

The 1541 Ultimate is capable of running both CP/M and GEOS.

In 2010, the 1541 Ultimate II was developed. The Ultimate II is about 30% smaller than the 1541 Ultimate, comes in a plastic case, and adds support for dual SIDs (plus a SID/MOD player), a USB host controller, tape emulation via a tape adapter (though use with a Commodore 128D requires modification), a real-time clock (for accurate file date and time), and the SD card slot is replaced by a microSD card slot. In addition, all firmware and VHDL code for the Ultimate II is available under an open source GPLv3 license, allowing hobbyists and others to freely modify all aspects of its functionality, including the FPGA-emulated hardware.

The 1541 Ultimate has an option for on-board Ethernet, while the 1541 Ultimate II supports Ethernet via a compatible USB to Ethernet adapter.

Besides being useful to retrocomputing hobbyists, it has also found use in educational laboratory settings.

In 2017 the Ultimate II+ was released with the following feature differentiation from the II:

Removal of the MicroSD slot, More USB ports, Integrated Ethernet, Dual Flash, Integrated Speaker, External power supply connector with auto-switch over circuit, Improved power supply circuits, and a slightly bigger and faster FPGA, as to control the new features. 

The II and II+ share a firmware image and the software features are substantially similar.

Peter Paddleford. Peter Paddleford (1785–1859) was a covered bridge builder who designed a new wooden bridge truss, one he never patented. The design was used widely throughout New Hampshire, Maine, and Eastern Vermont during much of the 19th century. Paddleford was also a millwright.

Biography
Peter Paddleford was born in Enfield, New Hampshire on September 14, 1785. He moved with his father, Philip, to Monroe, New Hampshire, in the early 1800s. In 1816, the younger Paddleford was issued US Patent 2,594X. The spinning device patented is not recorded as having been produced. In 1830 Peter moved to Littleton, New Hampshire, where he spent most of his remaining years.

In 1833, Paddleford unsuccessfully participated in a bid to build a bridge from Montreal, Canada island. In other bridges, Paddleford first utilised the Long truss design, but later created his own. This was challenged by others, who thought that Paddleford had stolen from the earlier designer. Paddleford never recorded his patent and it was used by others. His truss "superficially resembles the Long truss", but they had different purposes. Paddleford's design saw wide use, especially in New Hampshire, Orleans County, Vermont, and Caledonia County, Vermont.

His first self-designed bridge was possibly Joel's Bridge in Conway, New Hampshire, which was constructed in 1846, working in partnership with his son Philip. Peter Paddleford retired in 1849, although Philip continued to build bridges. Paddleford died on October 18, 1859.

Migration (virtualization). In the context of virtualization, where a guest simulation of an entire computer is actually merely a software virtual machine (VM) running on a host computer under a hypervisor, migration (also known as teleportation, also known as live migration) is the process by which a running virtual machine is moved from one physical host to another, with little or no disruption in service.

Subjective effects
Ideally, the process is completely transparent, resulting in no disruption of service (or downtime).  In practice, there is always some minor pause in availability, though it may be low enough that only hard real-time systems are affected.  Virtualization is far more frequently used with network services and user applications, and these can generally tolerate the brief delays which may be involved.  The perceived impact, if any, is similar to a longer-than-usual kernel delay.

Objective effects
The actual process is heavily dependent on the particular virtualization package in use, but in general, the process is as follows:

Regular snapshots of the VM (its simulated hard disk storage, its memory, and its virtual peripherals) are taken in the background by the hypervisor, or by a set of administrative scripts.
Each new snapshot adds a differential overlay file to the top of a stack that, as a whole, fully describes the machine.  Only the topmost overlay can be written to.
Since the older overlays are read-only, they are safe to copy to another machine—the backup host.  This is done at regular intervals, and each overlay need only be copied once.
When a migration operation is requested, the virtual machine is paused, and its current state is saved to disk.
These new, final overlay files are transferred to the backup host.
Since this new current state consists only of changes made since the last backup synchronization, for many applications there is very little to transfer, and this happens very quickly.
The hypervisor on the new host resumes the guest virtual machine.
Ideally, the administrative scripts resume backup operations, the new host becomes the primary, and the previous host now receives the backup copies, readying it for a subsequent migration operation.

Note that in practice, regular maintenance operations are required to "merge down" the snapshot stack into a more manageable number of files, to improve performance and optimize storage (redundant overwrites are merged out).

Relation to failover
Migration is similar to the failover capability some virtualization suites provide.  In true failover, the host may have suddenly completely failed, which precludes the latest state of the VM having been copied to the backup host.  However, the backup host has everything except for the very latest changes, and may indeed be able to resume operation from its last known coherent state.

Because the operations are so similar, systems that provide one capability may provide the other..
