Getting and Installing Linux – Part 5

Running Windows programs on Linux:

An overview of WINE and Virtual Machine

by James Stephens

In addition to all the software available for Linux, Linux also possesses the ability to run Windows software using either WINE or in a virtual machine. This can be valuable in many ways, from running legacy software to running Windows and Linux on the same machine at the same time.

WINE is the open source implementation of CrossOver, which Apple users may already be familiar. It is essentially a translator: WINE sits between a Windows application and the Linux system, presenting what appears to be a Windows system to an application and generating Linux instructions for processing. It’s not a perfect solution, but it’s pretty good. It’s fast and efficient, requiring little more resources then the application itself, making it suitable for older machines. When properly configured, Windows applications install as if in Windows and run on Linux like any other application. The backward compatibility of WINE is actually better then that of Windows itself. So if you have beloved but outdated software you can run it again with WINE. In my case that is a Windows 3.1 controlled audio mixing console. A lot of people like to play the old Windows 95 games.

New smallsat rocket company plans first launch in 2018

The competition heats up: Vector Space Systems now plans its first test flights of its Vector 1 will begin in 2017 with the first orbital flights in 2018.

[Chief executive Jim Cantrell] said he expects to do three or four orbital launches in 2018, increasing to 12 in 2019. “We’re going to call them test launches,” he said of the planned 2018 launches, “but we have a number of people who want to buy those launches already.”

Cantrell said Vector Space Systems has signed up one customer, and is in negotiations with a second customer, both of whom he declined to name. Both customers, he said, are planning satellite constellations. “Between those two, we will have sold close to 30 launches,” he said, with those launches spread out over several years.

Vector 1 is being designed to launch very small satellites weighing generally less than 100 pounds.

Trump considers fracking businessman for Energy Secretary

Good news if true: Reuters today reported that presidential candidate Donald Trump is considering nominating Oklahoma businessman Harold Hamm as energy secretary if he wins the election.

In addition to considering Hamm, who has also functioned as Trump’s informal energy adviser in recent months, the article also noted this:

Trump, who has yet to make any announcements about his prospective cabinet, has already surrounded himself with strong advocates of traditional energy sources like oil, gas, and coal and has promised to gut environmental regulations to boost drilling and mining if elected. He tapped U.S. Congressman Kevin Cramer of North Dakota, a climate skeptic and drilling advocate, to help draw up his campaign energy platform, and picked Indiana Governor Mike Pence, also a climate skeptic, as his running mate.

Both moves cheered the energy industry but alarmed environmental activists who say a Trump presidency would set back years of progress on issues like pollution and climate change. “Given that Hamm’s as close as we’ve got to a fracker-in-chief in this country, it would be an apropos pick for a president who thinks global warming is a hoax manufactured by the Chinese,” said leading environmental activist Bill McKibben.

I keep saying it: Should Trump win, the best way we can guarantee that he favors conservative values is if he is surrounded by conservatives. These moves suggest that that Trump is agreeable to this, though there is also possibly a bit of some crony capitalism going on here as well. While these guys will likely advocate for less environmental regulations, I also doubt that they will work to eliminate the gobs of corporate welfare the federal government presently hands out.

ULA chief says Congress deal clears path to Vulcan

The competition heats up: The CEO of ULA, Tory Bruno, said in an industry publication interview today that the Congressional deal that allows the company to buy 22 more Russian engines for its Atlas 5 clears the way for their eventual transition to the Vulcan rocket and an end to dependence on those Russian engines.

The article is worth a careful read, as it also provides a very detailed look at ULA’s future plans for its Atlas 5, Delta 4 Heavy, and Vulcan rockets. This paragraph was especially interesting:

The next major milestone is determining what engine will replace the [Russian] RD-180. Washington-based Blue Origin is developing the BE-4, a privately funded Liquid Oxygen (Lox) and Liquefied Natural Gas (LNG) engine capable of 550,000 pounds of thrust (lbf); and California-based Aerojet Rocketdyne is creating the AR1, a government-supported Lox/Kerosene (RP-1) engine capable of 500,000lbf. Either replacement will require two engines to match the power of the RD-180. Blue Origin claims its engine, already four years into development, will be flight qualified by 2017, while Aerojet Rocketdyne, having started its development later, says the AR1 will be flight qualified by 2019. Bruno said ULA would make its decision soon.

“Sometime close to the end of the year we are going to down-select, and then move into our Critical Design Review (CDR) and start manufacturing the rocket,” he said.

I strongly suspect they want to go with Blue Origin’s engine, because it is more powerful, farther along in development, and almost certainly less expensive. The question will be whether pressure from Congress, which favors Aerojet Rocketdyne’s engine for pork barrel reasons (Congress is funding it), will force ULA to go with it instead.

Flyboard Air company purchased

The company that designed the Flyboard Air jet hoverboard, featured here only two days ago in the Evening Pause, has been purchased by Implant Sciences, a company whose primary focus until now was explosive detection technology for the Homeland Security.

Implant Sciences is currently looking into the possibility of selling its explosives detection business, and the purchase of Zapata is subject to shareholder approval. Overall though, it seems pretty confident that the move could lead to big things. “We are beyond excited to have visionaries like Franky Zapata and his team on board and we are thrilled to allow for shareholders to benefit from the many breakthrough products he has already invented and the new innovations he will be unveiling in coming months and years.” said Implant Sciences president Robert Liscouski.

European commission approves Airbus-Safran buy of Arianespace

The competition heats up: The bureaucrats in the European Union have given their approval to the purchase by Airbus-Safran Launchers of Arianespace, thereby clearing the way for the privatization of that ESA entity and the construction, under Airbus-Safran control, of Ariane 6.

Following an in-depth review, the European Commission has approved under the EU Merger Regulation, the acquisition of Arianespace by Airbus Safran Launchers (ASL), a joint venture between Airbus and Safran. This approval is subject to conditions. Commissioner Margrethe Vestager, in charge of competition policy, said: “A well-functioning satellite and launcher industry is important to guarantee that European companies and institutions can gain access to space at competitive terms. The commitments offered by ASL ensure that after its takeover of Arianespace, all players in the industry will continue to have incentives to innovate.”

The Commission had concerns that the transaction would give rise to flows of sensitive information between Airbus and Arianespace to the detriment of competing satellite manufacturers and launch service providers. The Commission’s approval is conditional on the implementation of the commitments offered by the companies to address these concerns.

I must say that, in reading this story, I understood far better why the United Kingdom voted to leave the European Union. Though this particular deal is certainly different and involves many important government issues, if every private business deal is subject to the numbing concerns of this commission, I myself would run screaming from them as fast as I could.

Astronaut touts space at Republican convention

American astronaut Eileen Collins spoke last night at the Republican convention, calling for a renewal of the American space effort.

Her remarks were very short, essentially calling for an end to the American reliance on the Russians to get our astronauts into space. Her speech also differed from her prepared remarks in that she left out the part where she specifically endorsed Donald Trump.

According to a transcript of her prepared remarks provided by the GOP Convention to Syracuse University (her alma mater) and posted on the university’s website, however, the ending was supposed to be “We need leadership that will make America first again. That leader is Donald Trump. Thank you and God bless the United States of America.” Thus, although she did not read the line endorsing Trump, she did use his slogan “make America great again” instead of “make America first again” as in the prepared remarks.

The press will make a big deal about this, but I suspect that when it came time to say the words, Collins’ decades of training at NASA, where astronauts as government workers are specifically forbidden by the Hatch Act from lobbying for specific political candidates, took over. She clearly was supporting Trump. Habits just made it hard for her to become political, even though she is now retired from NASA.

What is important is that both she and Ted Cruz in their convention remarks both invoked the need for a vibrant American space effort, but both were vague about how to do it. Combining that with Trump’s already noted position, that we need a space effort but we also have to find ways to do this efficiently because the government has bigger priorities, suggests to me once again that, should Trump win, SLS and Orion will die quickly while commercial space will get a boost.

On a personal note, I am hoping that my policy paper, Exploring Space in the 21st Century, due out in about a month and focused very much on this precise issue, will land on these politicians’ desks at exactly the right moment, and help convince them to make what I think are the right decisions.

The Indian government considers privatization

The competition heats up: The Indian space agency, ISRO, is discussing with private companies ways in which it might privatize its smaller and successful rocket, the Polar Satellite Launch Vehicle (PSLV).

In order to step up the launch capacity within the country, ISRO is in the process of exploring the possibility of involving Indian industry in a greater role to meet the increased national requirements and possible commercial demand for launch services. Discussions are being held with the Indian industry towards formulating a plan and strategy to enhance the capacity as well as capability of managing the Polar Satellite Launch Vehicle (PSLV) programme on an end to end basis.

The sense I get from this ISRO announcement is that the government is taking the lead, trying to drag the private companies forward to take over. I also sense that both the private companies as well as ISRO are at the moment are somewhat uninterested in doing it. Neither impression is stated anywhere in this announcement and are merely my personal impressions, based literally on no inside information, which of course means I could be very wrong.

New Shepard aced its landing test

The competition heats up: According to an email sent out by Jeff Bezos, the recent New Shepard capsule landing test, with one parachute disabled, was a complete success.

Besides the three parachutes, New Shepard is slowed in its descent by a retrorocket that fires just before the capsule hits the ground. Bezos’ email also provided pictures of the “crushable ring” on the bottom of the capsule, which can help decelerate the craft if it hits the ground too fast (acting sort of like the bumper on a car). “Even with one chute out, the crushable barely crushed,” wrote Bezos, who is also founder and CEO of Amazon.com.

“When new, the crushable is about 5.5 inches [14 centimeters] high and can crush down to less than 1 inch [0.4 cm] high, providing a constant deceleration force as it crushes. After the mission, the crushable was still over 5 inches [12.7 cm] high along nearly the entire circumference of the ring,” Bezos wrote.

No word on when the next test flight will take place.

No 6207 A Study in Steel

An evening pause: A fascinating and well-filmed documentary from 1935 describing how a British company then built locomotives. Note the lack of construction helmets, gloves, or safety glasses. Note also the number of workers involved. Today most of this work is automated, making it more precise and efficient. Then, however, they did not yet have such technology, and instead found ways to build very sophisticated machines using the skills of ordinary humans.

Hat tip Edward Thelen.

Satellite hit by space junk, still operational

A private Earth-observation satellite, WorldView-2, was either hit by space junk or had some internal failure that produced “8 debris pieces” in its vicinity.

The Joint Space Operations Center, which is the Defense Department’s nerve center for space operations and tracks space objects from Vandenberg Air Force Base in California, tweeted July 19 that it had identified a debris-causing event related DigitalGlobe’s WorldView-2 satellite.

The amazing thing about this is that the satellite is still functional, and to prove it the company has already released an image produced after the event.

International space efforts to double in next decade

The new colonial movement: According to a new industry analysis, the number of countries with active space efforts will double to almost fifty in the next decade.

By 2025, we estimate that the number of emerging space programs will increase to 47 countries around the world. This includes 23 newcomers who will have committed their first investment in space between 2016 and 2025. Over 130 satellites are forecast to be launched in the next 10 years, nearly double that of the last decade. The total value of these satellites should more than double at nearly $12 billion, versus more than $5 billion during 2006-2015.

The new efforts are not confined to the traditional space programs, but also include nations that will be purchasing services from others to build satellites for them.

Franky Zapata demonstrating his Flyboard Air

An evening pause: Hat tip t-dub, who wrote that the Flyboard Air “is a real product developed by Franky Zapata. It’s a jet powered board that reminds me of what the Green Goblin used in Spiderman. This video was done in Monaco during the Formula 1 race this year. His company is called Zapata Racing and he has developed a jet pack, water hover board, and those fire hose things people use over water which is a hydraulic Flyboard I believe. If they only had this stuff back in the 70’s when I was growing up.” T-dub also added, “The Flyboard can go up to 10,000 feet, fly at 98 MPH, and has a duration of almost ten minutes depending on use. They have also set a Guinness record with the device.”

My thought: Once again, life imitates art.

New rocket company raising investment capital

The competition heats up: Two former employees of SpaceX and Blue Origin have teamed up to start their own rocket company, aimed at using 3D printing technology to build rockets “with zero human labor.”

The funding rounds are described in two documents filed in May and this month with the Securities and Exchange Commission. The first filing reports that $1.1 million in equity was sold to investors. The second filing serves as a new notice of $8.4 million in equity sold, out of a $9.6 million offering.

The filings indicate that Relativity Space is based in Seattle, but in response to an email inquiry, the company declined to say anything further about its location, its business plan or its investors. “We are entirely in stealth mode and will comment more when we are ready,” the company said.

New companies come and go, but the fact that the guys in charge of this come from these two companies, and have already raised significant investment capital, suggests attention should be paid.

Reused Dragon cargo capsule to ISS within a year

The competition heats up: SpaceX hopes to launch a previously flown Dragon capsule to ISS sometime with the next year.

This fall, SpaceX plans to refly one of its landed Falcon 9 rockets for the first time — and a Dragon capsule should make history by launching on a repeat ISS resupply mission shortly thereafter, a NASA official and a SpaceX representative said during a postlaunch news conference Monday. “I think we’re looking at SpaceX-11,” said Joel Montalbano, NASA’s deputy manager of ISS utilization, referring to the 11th resupply mission the company will fly with Dragon and the Falcon 9. (Monday’s launch kicked off SpaceX-9.)

I had been wondering when SpaceX would try to reuse a Dragon, and had assumed the reason it hadn’t happened yet was partly because of NASA reluctance combined with the delays connected with the launch failure last year. Either way, it appears that NASA is now on board and that the company is beginning to gear up for that first reflight.

SpaceX seeks two more pads for returning 1st stages

The competition heats up: SpaceX is asking for permission to establish two more landing pads so that it will have the capability of landing three first stages all within minutes of each other.

“SpaceX expects to fly Falcon Heavy for the first time later this year,” the company said in a statement responding to questions. “We are also seeking regulatory approval to build two additional landing pads at Cape Canaveral Air Force Station. We hope to recover all three Falcon Heavy rockets, though initially we may attempt drone ship landings” at sea.

This news suggests two things: 1. The first Falcon Heavy launch is definitely coming soon. 2. They are going to try to return all three 1st stages during that first launch.

SpaceX chooses recovered first stage to reuse

The competition heats up: SpaceX has chosen as the first Falcon 9 first stage to reuse the one that was the first to land successfully on a barge on April 8.

Though they have not announced the mission it will fly, I strongly suspect it will be one of the two SES communications satellites scheduled to launch in the fall. SES has already said they want to buy a launch using a re-used first stage, and the two SES satellites scheduled for the fall have some redundancy between them.

Getting and Installing Linux – Part 4

The Software Manager

by James Stephens

A computer is nothing more than a toy unless it has the tools you need to get your work done, and Linux has a great set of tools. Most distributions come loaded with the tools most people use every day, a full office suite, graphics and media packages and so on. If you want more, a world of software awaits at your fingertips via the Software Manager. Think of it as the app store for your distribution, with tens of thousands of official titles vetted and available for download, most free of charge. No longer are you left to the wilds of the Internet to find what you need.

Most Linux Software is functionally equivalent to that of Apple or Windows. Most open source titles are ported to all platforms including Linux. So if you use an open source title such as Audacity or VLC media player, just type its name into the Linux Software Manager search bar and you will find it. For propitiatory titles such as Photoshop just define what it does, image manipulation for example, and the Software Manager will suggest Linux equivalents like GIMP or KRITA. In addition Photoshop and some other Windows software run great on Linux using WINE – the Windows compatibility layer. More about that later.

Want to get a close look at the Russian spaceport during a launch? You can!

The space tourism company that has partnered with the Russians to fly tourists to ISS is now offering a nine-day tour of Russia’s launch facilities, including watching a Soyuz manned launch for the bargain price of $14,495.

Guests will get to see the launch of the Soyuz spacecraft on its way to the International Space Station and experience the live Soyuz-International Space Station docking at Mission Control Center. “We will observe the early morning roll-out of the Soyuz Rocket and follow it to the launch pad site together with the press, military personnel, cosmonauts, and their relatives,” said MIR Corporation President Douglas Grimes. “The following day we will gather in a VIP seating gallery at Mission Control Center for the live satellite feed of the Soyuz docking.”

Guests also have the option to participate in cosmonaut training themselves: They can experience up to 4 Gs on the world’s largest centrifuge, take a parabolic zero-G simulation flight, don a spacesuit, and learn how to handle “typical space tasks.”

DARPA pushes its Experimental Spaceplane program forward

The competition heats up: DARPA outlines its goals for its Experimental Spaceplane program (XS-1).

Key to the effort is DARPA’s recognition that since 2000 under the government’s EELV program, launch costs for the military had increased significantly, while the launch rates appears to slow.

According to DARPA’s presentation, the Pegasus, Minotaur, and Antares launch vehicles only fly one DoD mission per year at a cost of ~$55 million USD per flight.

SpaceX’s Falcon 9 currently performs ~3-6 DoD missions per year at a contract price equal to or greater than $54 million USD per flight.

That price per flight then jumps dramatically for United Launch Alliance’s (ULA’s) Atlas V and Delta IV launch vehicle families – which currently perform about 8 DoD flights per year for a cost per flight in excess of $400 million USD. [emphasis mine]

ULA claims that they charge the Air Force an average of $225 million per launch. DARPA says it is $400 million. Either way, that is a lot higher than the $83 million that SpaceX charged for its first Air Force contract.

The article then provides a nice overview of the XS-1 program, which like NASA’s commercial space program is asking private companies to come up with the new designs and technologies rather than have the government try to do it. All DARPA is doing is laying out their basic requirements, fly 10 times in 10 days for less than $5 million per flight.

The program is now shifting to its second phase, which will call for actual construction proposals late this year, with the hope of test flights by 2019.
