The Martian : Novel

 

When I heard about this book I immediately wanted to read it, being a Space enthusiast and very interested in the journey to Mars, I had to know how one man stranded on the red baron planet would try to survive.

Mark Watney an astronaut on the Ares 3 mission to Mars was left stranded following a storm. His crew thought he was dead after seeing his suit lose pressure and had no choice but to evacuate the planet. Miraculously he survived the storm only to realise that he had been left behind. He is forced to ration out his food and find a way to survive until the next planned mission to Mars.
This novel is incredibly scientific and filled with calculations and accurate assumptions about Mars. As a botanist and an engineer it doesn’t take long for Mark to become the first farmer on Mars. Using the potatoes planned for Thanksgiving, Mark prepares them for planting. By cutting each potato into segments with two eyes each he carries Martian dirt into the Hab which are his living quarters. He then mixes the dirt with his own waste to encourage the growth of bacteria for his potatoes. As well as food, Mark needs to increase his water, so it’s not long before he passes hydrazine over a catalyst to help produce water for his survival.

Andy Weir has created a realistic character that has attitude and is wise cracking. Although no one can relate to being stranded on Mars, his emotions can be related to. He admits from the beginning he is screwed but doesn’t bow down to defeat for long before establishing an escape plan. Not forgetting I probably laughed at this book more than I should have. I’m sure your thinking I’m sadistic in laughing at a man stranded on Mars but Mark Watney is one hilarious character. Even during the times when it looks impossible he had some witty comeback or hilarious remark. Without a character like Mark Watney, this book would have been a scientific look at survival on Mars; instead what we have is a realistic look at an intelligent human being stranded on Mars. Apart from the few questionable scientific interpretations, this novel really does capture what it would be like to be the only person on an inhabitable planet.
This novel has come at the right time when NASA plans to reach Mars by 2030 and no doubt this will create some positive press for them and give them that nudge towards the necessary funding they need, that being $80 to $100 billion over the next 20 years. Not to mention the movie released starring Matt Damon as Mark Watney will play a big part in hitting an audience of film enthusiasts about a trip to Mars, even if they don’t read the book.

'Recalc Or Die': 30 Years Later, Microsoft Excel 1.0 Vets Recount A Project That Defied The Odds

Microsoft has recently been making lots of apps for iOS and Android, despite the fact that those platforms are rivals to its own Windows operating system. But this is actually not a new phenomenon at the company.

Mike Koss runs Excel 1.0 on a 512K Mac this week.

Just ask Doug Klunder, the lead developer for Microsoft Excel 1.0, who quit his job after Bill Gates and other Microsoft leaders decided to shift the original Excel project from MS-DOS to the Apple Macintosh more than three decades ago.

Klunder ended up coming back to Microsoft and finishing the project, after an ill-fated stint as a farm worker in the lettuce fields of California. But even today, with Excel still going strong, he isn’t convinced Microsoft made the best choice.

“I’m still not entirely sure it was the right decision,” he said this week, laughing with his former Excel colleagues. “In some ways it worked out well, but it did put us years behind, because we shipped on the Mac and gave Lotus that much longer to consolidate on the PC platform. I still think we could have taken them on.”

Klunder was one of four members of the Excel 1.0 team who joined us to record a podcast (below) at the GeekWire offices this week, reflecting on the creation of one the most important products in Microsoft’s history.

Software developer Mike Koss, the unofficial historian of the original Excel team, brought an original 512K Mac running the first version of Excel on floppy disks, a “Recalc or Die” motorcycle jacket and shirt, technical documents and other memorabilia from the Excel 1.0 era — mementos of a landmark Microsoft product.

“Microsoft really bet its future on two programs at right about the same time: Excel and Windows,” Klunder said. “If both of them had failed, Microsoft wouldn’t be here today. Both of them succeeded. It really helped cement Microsoft’s role.”

This weekend, many of the original Excel team members are getting together to celebrate the 30th anniversary of the software’s release, along with others who have been involved in Excel over the years. (Members of the extended Excel family should email excelis30@outlook.com for info and to RSVP.)

Doug Klunder, then and now. He’s now a lawyer who does privacy work for the ACLU.

Thirty years later, their passion for the project still runs deep — as evidenced by Klunder sticking to his guns on the company’s Mac vs. DOS decision. It’s clear that one of the main reasons Excel beat out rivals such as Lotus 1-2-3 and VisiCalc was the determination and ingenuity of the original team.

Of course, there were other factors, as well.

“It’s important to point out that largely it was a matter of ripping off really good ideas from other products,” said Jabe Blumenthal, who was Microsoft’s first program manager, working on the Excel team. But he quickly noted, “Doug will take exception to that because he did some really cool original stuff.”

Klunder said, “We certainly ripped some stuff off, but we also did some things that nobody else had done at the time and probably hasn’t done since — some of which are really insane, and some of which turn out to be pretty handy.”

Mike Koss, a member of the original Excel team, is now a software developer at Google. He has been an active member and organizer of Seattle’s startup community.

This is where “Recalc or Die” comes in. One of Excel’s features was “intelligent recalc,” created by Klunder, which gave Excel an advantage over Lotus 1-2-3 by being smart about the way it recalculated cells in a spreadsheet.

Rather than recalculating all the cells when one cell was changed, it selectively recalculated cells affected by the change — making the program more efficient and improving its performance on the limited hardware of early personal computers.

This feature was important enough that Bill Gates took a special interest in it. “Bill was very interested in the recalc problem,” Koss said. “I remember having meetings with him into Excel 2, Excel 3, where he was very interested in getting an optimal recalc and doing better.”

But the significance of the feature was also a risk, because Klunder was the only one who knew its secrets.

“Just imagine having this product where one of the key components of it is really only understood by this guy who will quit routinely and go be a migrant farm worker down in California,” Blumenthal said, laughing with the group. “It was not necessarily the most traditional or stable of environments.”

Jabe Blumenthal, Microsoft’s original program manager, is now focusing on climate and clean energy advocacy, including work with Bill Gates. He taught high school math and physics after leaving Microsoft.

Excel was a learning experience for everyone. Blumenthal, for example, recalled initially being skeptical about his colleague Steve Hazlerig’s idea to “print” a document to the screen as a way of checking the output before printing to paper. Blumenthal couldn’t understand why anyone would want to do that. But he recognized that he could be wrong, and that Hazlerig had more experience with printing than he did. And so he let the feature live.

“I’m so, so glad that I don’t go down in history as the person who killed Print Preview,” he said.

Blumenthal pioneered the position of program manager at Microsoft, and the way he handled the Print Preview situation was characteristic of the best program managers, said Jon DeVaan, another Excel 1.0 team member, who would go on to become a high-ranking Microsoft Windows and Office engineering executive before leaving the company in 2013.

“The best program managers do what you just said,” DeVaan told Blumenthal during the conversation this week. “The people that struggle more in the job are the people that want to be in charge, and that doesn’t work out so well. The reality is, everybody is really passionate about what they do, and they want to have a voice in how things turn out. The best way to handle that is to allow the expression to happen, and come up with a good decision.”

Jon DeVaan went on to become a key Microsoft engineering executive for Office and then Windows, before leaving the company in 2013.

Among other tidbits, they shared the fact that the product almost didn’t end up being called Excel. “Odyssey” was the code name, and product names that were considered included “Master Plan” and “Mr. Spreadsheet,” before a professional naming firm came up with the final brand.

Many of the original Excel team members still use the program today — the RSVP sheet for this weekend’s party is an Excel Online document — and take pride in the software’s impact on the world.

“It’s been so much fun,” said DeVaan. “Everywhere in the world I’ve ever been, people know what Excel is, and can tell their stories about how it empowered them, and it’s just awesomely cool.”

“It’s not like there wouldn’t have been a dominant spreadsheet in the world had it not been Excel,” said Blumenthal. “It’s always important to start these things off by saying, the brilliant invention was the invention of VisiCalc. But it’s so cool that I got to participate in this thing at such a ridiculously young age with a whole bunch of really fun and inspiring people to work with. Every day I thank my lucky stars for having had that experience.”

“The world, I don’t think, looks any different than it would if we hadn’t done it, because somebody else would have done it,” he said. “But that’s OK. We got to participate in something incredibly fun.”

Nokia 1100 is Still the Biggest Selling Handset in the World

The world’s best selling phone is not the iPhone but something very old and not a smartphone at all? Remember the classic old Nokia 1100, the phone we all perhaps began with? While the iPhone 6 may have sold 71 million units in about three months, the numbers have nothing on the Nokia 1100.

 

The Nokia 1100 was an entry-level handset that came out in 2003. At the time it was perhaps the best thing to ever hit the mobile market. Lets consider this a 2003 post and talk of the specs that makes the phone a true badass. The handset does not come with two cameras, a curved screen or a snapdragon processor. What it does feature is a torch-light, a pair of no-slip grips, dust-proof case, monochrome graphic with, wait for it, 96 x 65 pixels, monophonic ringtones (36 pre-installed, 7 user-made), interchangeable covers, and an unbreakable will (we mean it).

This smooth handset can also store up to 50 contacts and 50 messages (25 sent, 25 received) and gives a whopping 400 hours standby time between charges. But the one thing that really tied this phone together was Snakes II and Space Impact – those 8-bit games that were played by 250 million people around the world.

We say 250 million because that’s how many units of the Nokia 1100 were sold by 2008, becoming not only the world’s best selling phone, but also the best selling consumer electronics device. There are many reasons behind why the 1100 was the craze at the time. For one thing, the phone was highly affordable at about $100 with all the features mentioned above, which were all that one needed at the time.

The phone was discontinued in 2008 because of the next wave of phones that were coming in, However, in 2009, the obsolete device became something of a collectors item as they were being sold for obscene amounts of money – say $32,000 a piece.

But if you thought you had seen the last of the Nokia 1100, think again. There are rumors that the classic handset might come back with a technological makeover. In March this year, the Nokia 1100 was seen in a GeekBench’s database and suggested that the 2016 Nokia 1100 will feature a quad-core 1.3GHz MediaTek MT-6582 processor and will reportedly run on Android 5.0. However, this could all be an elaborate ruse by Nokia to use an old model since under the terms of its deal with Microsoft, Nokia cannot offer a new smartphone under the last quarter of 2016. It would be fun, though, to see what the 1100 would look like fitted with all the new toys today.

How to Block banner popups on any website domain, using AdBlock

 

Recently there has been some news on the net about the morality of adblock software. On one side, ads are required to run a site, as it generates revenue. On the other side, users have had enough of in-your-face huge ads which consume bandwidth and complicate browsing.

Many sites welcome visitors with huge banners taking up the entire front space, pushing the visitor to a hostage like scenario. Extensions like adblock do a good job of blocking ads on the side of the page content, but cannot block (or do not block, I am not sure) these huge banner ads. Adding a simple rule to the adblocker can  fix the problem for you.

For instance, this is what I got when I visited the website of a news paper in India

 

Heres how to block this ad completely in the future on this site.

1: Install AdBlock extension in your browser.

2: On getting this banner ad, right click on the banner itself and choose Adblock->Block this ad.

3: You will now get a popup with a slider on it. Adjust the slider to the right, so that the banner ad and the transparent overlay disappear completely.

 

4: Click on Looks Good. And on the next pop-up, confirm by clicking on the Block It ! Button.

Adblock will not add a rule into the system, so that any HTML DIV where Id = nlpopup is blocked on this domain.

Thats it ! You will never ever get this ad on this domain again..

Well..until they change the ad DIV or decide on more banner ads again.

Cya !

Antikythera Shipwreck Yields New Cache Of Ancient Treasures

 

Over 2,000 years ago, the churning ocean below the cliffs of the Greek island Antikythera swallowed a massive ship loaded with a trove of luxuries—fine glassware, marble statues and, famously, a complex geared device thought to be the earliest computer.

Discovered by Greek sponge divers in 1900, the shipwreck has since yielded some of the most impressive antiquities to date. And while severe weather has hampered recent dives, earlier this month a team of explorers recovered more than 50 stunning new items, including a bone or ivory flute, delicate glassware fragments, ceramics jugs, parts of the ship itself and a bronze armrest from what was possibly a throne.

“Every single dive on the wreck delivers something interesting; something beautiful,” marvels Brendan Foley, a marine archeologist at the Woods Hole Oceanographic Institute and co-director of the project. “It’s like a tractor-trailer truck wrecked on the way to Christie’s auction house for fine art—it’s just amazing.”

The wreck of the Antikythera ship hides beneath a few feet of sand and scattered shards of ceramic fragments at a depth of about 180 feet. Following an initial excavation funded by the Greek government, explorer Jacques Cousteau returned to the wreck in 1976 to mine the seemingly endless bounty, recovering hundreds of items.

But with even more modern advances in diving and scientific equipment, scientists believed the Antikythera wreckage had more secrets to reveal.

In 2014, an international team of archaeologists, divers, engineers, filmmakers and technicians embarked on the first excavation of this site in 40 years, using detailed and meticulous scientific techniques to not only find new treasures but also to try and reconstruct the ship's history.

The team used autonomous robots to produce hyper-precise maps of the site in partnership with the University of Sydney Australia, says Foley. These maps—accurate down to about a tenth of an inch—were pivotal for both planning dives and mapping discoveries.

The team also carefully scanned the site with metal detectors, mapping out the extent of the wreckage and deciding where to excavate. Using waterproofed iPads, the divers could mark each new artifact on the map in real time.

For the latest round of dives, a ten-person team logged over 40 hours underwater, surfacing with the fresh haul. Analyzing the artifacts should provide the team with a wealth of information, says Foley.

The Antikythera shipwreck is spread across two different sites separated by about the length of a football field, he says. Analytic tools, like comparing the stamps on amphora handles from each site, will help scientists determine whether the wreck represents one or two ships.

If it was two ships, “that opens up a whole series of questions,” says Foley. “Were they sailing together? Did one try to help the other?”

Still, the large size of objects recovered at the primary wreckage site suggests that at least one ship was massive, akin to an ancient grain ship. One such item recently recovered as part of the latest haul was a lead salvage ring about 15.7 inches wide, used to straighten tangled anchor lines.

Scientists hope to learn more about the origin of the ship—or ships—by analyzing the isotopic composition of lead artifacts similar to this ring, which will yield information about where the vessel itself was made.

For the ceramic artifacts, the team plans to look closely at any residues preserved inside the container walls. “Not only are [the ceramics] beautiful in their own right, but we can extract DNA from them,” says Foley. That could give information about ancient medicines, cosmetics and perfumes.

The team currently has plans to head back out to the site in May, but the future of the project is open-ended. With so much information to glean from the current set of artifacts, Foley says that they could let the site sit for another generation. With the rapid advance of technology, future expeditions may have even better techniques and be able to discover even more about the wreckage.

“What will be available a generation from now, we can’t even guess,” he says.
