How powerful was the Apollo 11 computer?

I got to thinking, how powerful was the computer that took Man to the Moon back in 1969? How does the Apollo computer compare to the iPhone? (Who wants to go to the Moon, anyway?)
It turns out that’s a tough comparison to make, as the simplest of iPhones is so advanced compared to the technology used in Apollo’s guidance system that it’s hard to believe they both came from the same planet, and we can be pretty sure that we’re dealing with some really archaic hardware.

Indeed, those Big Machines were nothing short of amazing. Comparing the Apollo Guidance Computer (AGC) to an IBM PC XT. Did you know that the 8088 which formed the basis for the IBM PC, released in 1981, just a decade after Apollo 11′s trip to the Moon, had eight times more memory than Apollo’s Guidance Computer (16k, vs the Apollo’s 2k). The IBM PC XT ran at a dizzying clock speed of 4.077MHz. That’s 0.004077 GHz. The Apollo’s Guidance Computer was a snail-like 1.024 MHz in comparison, and it’s external signaling was half that.

Internally, the architecture of 8086 had 8 16-bit registers available to work with. It could keep track of eight registers, the Apollo Guidance Computer held just four.

The most amazing part that’ll blow you away isn’t so much the hardware, as the software they used to get to the Moon. In fact, the real-time operating system in the Apollo 11 spacecraft could multi-task eight jobs at a time, something we take entirely for granted today, but no small feat for the time it was developed.

Multi-tasking however, wasn’t quite as we now think of it. Our operating systems use pre-emptive -multitasking, where the operating system itself is in control of the execution and can stop any program at any time. The AGC relied on non-pre-emptive multi-tasking, whereby programs had to relinquish control back to the OS periodically.

The Apollo system also implemented a virtual machine which offered more complex instructions, and could be used to perform more advanced mathematics. For its time, this was way-out stuff in 2k of memory and 32k of storage. The OS managed transition between native instructions and the instruction set of the virtual machine, which let developers mix and match the hardware level instructions with the virtual instructions within the same assembler code.

Even more, the Apollo 11 was actually the advanced “Block II” version of the AGC – the earlier missions had relied upon as little as 24k of core read-only storage, and only 1k of main memory!

And what about interface? The AGC was way switches and blinking lights, and every command was entered in a combination of “verb noun pairs”, which would be input as numbers. These numbers were translated into English on a painted sign in the spacecraft.

The Apollo Guidance Computer had only one error message, and when it flashed, it meant the real end was near. On the Apollo 11 mission a 1201 error, and then a 1202 flashed causing enormous concern on the lander and back on Earth, after the spaceship crew had mistakenly left one radar system on, while the landing crew used a second system to determine the distance to the ground. The computer was taking in too much data to function, and left the crew in the lurch.

So, when you think about all those amazing manned missions to the Moon, and what it took to get there, keep in mind that had the complexities of the eventual AGC been understood when the NASA team began to design it, they likely never would have started, as they would have considered the computer far outside the available technology of the day.

We take interplanetary travel for granted today. One day Man is going to do the same with interstellar travel. And people will smile just looking at today’s iPhones and iPads, so obsolete and so out-of-date toys the Humans had to deal with to communicate.

The Killing Machine!
Posted by admin

killing masine

How many people do you reckon are hit by subway trains? Well, if you think, the number is rather small, you are wrong. Hundreds are struck by subway trains every year, with dozens of them killed. The statistic includes people struck while leaning over from the platform and those who climbed onto the tracks to retrieve dropped devices, purses or umbrellas. At least 50 New Yorkers get killed or hurt while trying to get back the iPhone they had dropped on the tracks, every year!
Men and women go onto the subway tracks to retrieve their dropped iPhone, and are electrocuted and fatally struck by trains. They try to grab their toys, but end up electrocuting themselves.

Physicians regularly get patients who were hit by subway trains, and they come in with limbs ripped off and whole sides of their bodies broken. Indeed, some people learn safety the hard way.

Have you ever noticed how when the train flies by there’s that gust of wind that pushes you away and then pulls you back in? Well, lots of people are hit this way and many of them are victims just because they were talking over their smartphones, not paying attention to the train. Texters do not realize just how strong the wind is or they get startled and jerk the wrong way.

When a train is late or during the rush hours, the platform gets more crowded, and in this case people edge closer to the tracks and sometimes there is literally no space left on the platforms, with people backed all the way up the stairs.
But don’t tell me that there is no possible way for people not to be crowded all the way up to the edge. While the situation is unsafe, the passengers should still have the sense to avoid leaning forward, but they text, and they talk, and they watch their Youtube movies and listen to their nice Tunes songs. And they drop their iPhones on the tracks, too.
They say that the authorities must install doors to avoid all these accidents. It will prevent many deaths (and also prevent trash being blown onto the tracks). Door systems will also regulate air movements in the stations and allow the introduction of air cooling to platforms. It would be expensive, but these are human lives we are talking about.
Until the doors are in place, the main issue is not getting on the tracks, because this is extremely dangerous. Just think again, how many people are honestly risking their lives for their iPhone and get hit by the train? Don’t be the next statistic, don’t jump down to retrieve cell phones and stuff you’ve dropped.

Finally, let’s remind you that you can just stand by wall, behind third rail if a train comes, or even crouch underneath the platform, which always has a considerable overhang specifically designed so people can get out of the way of trains. But we strongly advise you just go and ask a manager, if you dropped your smartphone. And if you can’t avoid this urge to jump down to try and grab it, just sell the smartphone before it’s too late.

New iPhone 6

New iPhone 6, specifications and price
At a glance, some more important rumored specifications of this new and highly publicized iPhone 6 to be launched in September (see our text XXXXXXX) are as follows (at least, this is what we think we know about this device)
Two versions will be available in the market: 4.7-inch and 5.5-inch with a sapphire glass display; 2GHz+ processing power and 1GB RAM, which is the same power sported by the iPhone 5 product line but less than Samsung’s Galaxy S5. The camera will have optical image stabilization, but no update on 8 megapixels. (Let’s remind you that optical image stabilization (OIS) is designed to reduce shake and improve the sharpness of images, and is often found on high-end DSLR lenses. In fact, the iPhone will retain its 8 megapixel camera – rather than be upgraded to 12 – 16 megapixels, but image stabilization would improve the camera’s capabilities.
However, there’s no shortage of rumors floating around and concerning its specs, price and other details. For example, they say that if you sell you old iPhone to change it for the anticipated Apple new flagship phone you might have to buy the iOS handset (the Wall Street Journal suggested that two types of handset would be on offer, both of which will have larger screens than the 4-inch iPhone 5). According to new patents filed by Apple, the new handset could be thinner than its predecessors and standard aluminium-framed handsets, and Apple may use the LiquidMetal technology that it licensed in August 2010 and renewed this summer to bind a Liquidmetal bezel to a sapphire glass screen.
A sapphire glass screen is also a debated aspect of the iPhone 6, and smaller bezels and an expanded use of screen real estate are expected to increase display size without making the iPhone itself much larger.
As to its 4.7-inch and 5.5-inch versions, the curved glass screens are supposed to detect different levels of pressure thanks to new sensors. Some experts claim the iPhone 6 could sport a screen resolution of up to 1704×960.
Some gurus believe that Apple’s newest phone will contain a faster A8 processor. It seems that Apple’s A8 SoC will boost frequencies of 2GHz or more per core, an increase from the iPhone 5S’ 1.3Ghz A7 SoC. However, the chipset will continue to use dual-core architecture. Certain sources claim that the iPhone 6 will feature a Qualcomm MDM9625 modem, which lacks support for LTE Category 6, but is faster. If this rumor happen to be true, the iPhone 6 could reach data speeds of up to 150Mbps, carrier allowing, but will not be capable of 300Mbps speed.
But what about battery life? According to Apple Daily the larger iPhone will pack a powerful 2915 mAh battery, while the smaller version will sport a cell with capacity between 1800 and 1900 mAh.
Rumors say that wireless charging for iPhone 6 may also be on the cards, as following a patent filed by Apple in 2012 for wireless charging protocols, the possibility exist of charging this device without wires.
Other reports suggest the iPhone 6 will come with Apple’s biometric fingerprint scanner TouchID, and retina scanning technology could also become part-and-parcel of our future handsets.
Finally, it seems that iPhone 6 is the first to feature an Apple logo which lights up when the user is sent notifications, besides, its secret weapon will be new types of vibrator which will allow app developers to vary levels of vibration depending on the handset activities. Details are thin on the ground surrounding the iPhone 6′s rumored price, but we are expected to pay prices that will match the iPhone 5S.

Don’t forget that the iPhone 6 has an expected launch date of 9 September, before going on sale on 19 September 2014, as Apple has reportedly ordered up to 80 million units ahead of launch, so it’s time to sell your old iPhone before it’s too late.

Aliens and iPhones

The historical records of our planet speak of ongoing contact with extraterrestrials as found in oral traditions, stone monuments, clay figurines, tablets, petroglyphs, art forms found throughout Earth. Many of these images could also be lenticular clouds. For example, the Ubaid culture which succeeded the Halaf at the end of the 6th millennium B.C. in southern Iraq, then spread throughout Mesopotamia, is known for painted pottery and typical lizard-headed figurines of both male and female gender holding a strange object which resembles an Apple iPhone. But similar lizard-headed figurines have been found in Central America and on the Caribbean Islands. How did these artworks land there and what is their meaning. Did they sell iPhones 7 thousand years before in Dominique?

The Lolladoff plate, discovered in Nepal shows a hovering disk-shaped object in the center and a small being, resembling an alien gray with a circular tablet or a phone in his or her hands. The circular pattern is reminiscent of the spiraling movement of consciousness – Sacred Geometry of creation.

Strange suited figure at least 5 thousand years old have been recently found in Kiev, Ukraine. These two men seem to talk to each other over a cellular phone.

Petrographs dating back at least 4 thousand years ago were made by ancient Indians in the American Southwest. According to Indian folklore, two objects collided high in the sky and one crash-landed in the region of Death Valley. The survivors called for help over a small craft actually resembling our modern iPods. A rescue team arrived (presumably in another ship) and spent some time repairing the damaged craft and were observed by the local Indians.

The Indians depicted the ship and the mobile phones used by the men who came to repair the damaged craft. Two of the cell phones were left (presumably forgotten) when the visitors flew away, but the locals who tried to communicate using them were able to talk only for few days, and then they “came into silence forever”.

Could it be, the alien technology has been carefully preserved for centuries and even millennia by some of our ancestors who finally decided to give us a chance to communicate using the well forgotten ancient method?

Nicaragua and iPhone
Posted by admin
two nice Nicaraguan parrots

Nicaragua’s communications infrastructure allows you to communicate in a variety of ways, from land line telephones to Internet access, and if you want to keep in touch with family and friends during your stay in this country your iPhone is the best way to do it.

International calls made to telephones outside of Nicaragua can be made by means of direct dialing or through and international operator, these can be quite expensive depending on where you are calling. Enitel is the main telephone operator in Nicaragua. Most tourist destinations within Nicaragua will have land line connections and international direct dialing is available. But telephone charges can change so you should therefore consult the telephone company to find out the costs.

Due to the increase in popularity of iPhones, Nicaragua is quickly expanding its cellular services and infrastructure, and network operators continue to improve their coverage. Till now, the best cellular coverage is in and around major cities, but reception is available throughout the country and thus your iPhone will help you to stay in touch with the external world. Phone rental is also an option in Nicaragua, but this service is not available everywhere. However, internet connections are available in the majority of Nicaragua’s cities, making Internet access quite wide.

Nicaragua’s government subsidizes the country’s Internet cafés and therefore charges in them are inexpensive. These Internet cafes are great if you want to browse the Internet or send e-mails, besides, you can also make less expensive international calls from Internet cafés by means of VOIP systems.

If you have a iPhone with a service, you can purchase an iPhone international plan from your company that will allow me to use your iPhone while in Nicaragua, and the service exists outside of Managua, its capital.

But don’t look to make phone calls, as they will be expensive, you’ll just want to send the occasional text and check the internet and eMails.

Don’t forget that if you get an international plan from your company, and it will work here, you’ll need a phone that is compatible with the networks. You can call your company help line and they can give you more info by looking at your account and phone and let you know if it will work, and what kind of plan you need if it will work.

Depending on how long you are there though, it may just be cheaper to purchase a cheap phone in Nicaragua and use that locally. You may want to sell your iPhone in Nicaragua, as they are rather expensive, but keep in mind that you’d better do it through your hotel employee or in an Internet coffee shop.

The Nicaraguan government hopes the situation with iPhones will change as the project of the Nicaragua Interoceanic Grand Canal, a proposed waterway through Nicaragua to connect the Atlantic Ocean with the Pacific Ocean, is moving forward.  The planned canal, the project of the century, could be about 175 miles long, with locks big enough to accommodate the biggest new container ships. The project also includes provisions for the construction of deep-water ports, free-trade shipping zones, an international airport, an oil pipeline, and a railway linking the Atlantic and Pacific Coasts of Nicaragua.

It’s been a dream a long time… we’ll see very soon if the dream becomes a nice reality for Nicaragua. The iPhone will come with the Canal and everyone will talk one to another as two nice Nicaraguan parrots, as a great writer Megan Jorgensen used to say. Photo : © Igotoffer.com

iPhone 6 is coming in 2014

iPhone 6 is coming in 2014

 

 

 

http://igotoffer.com/

  What Apple is saying gives an insight into what the iPhone maker is juggling ahead of its smartphone’s launch supposedly on September 9, 2014. In this event Apple’s iPhone 6 upgrade cycle may be largest ever… Indeed, the iPhone sales account for more than 55 percent of the company’s sales, and Apple can’t afford to fluff it up. According to Wall Street analysts, Forget iPhone 6 will be the “main catalyst” for Apple’s year-round sales growth as Samsung and other rival phone makers have expanded into the larger display model.

 

The three-month period, around the December holiday period, as smartphone saturation rate hits its peak, could cause Apple to sink or swim, as it typically accounts for the company’s greatest sales period in the year.   If Apple were to play its cards right, a larger iPhone will help “boost handset replacement demand” for existing owners, and help Apple win back market share of high-end smartphones from Android. Rumors continue to swirl on exactly what sized devices will be paraded on Apple’s launch day. We think it is “imperative” for Apple to launch the phone in two sizes – a slightly larger 4.7-inch device and tablet-sized 5.5-inch, before the end of the year. It seems Apple’s focus on design and “making the best products,” rather than focusing on maximizing sales, means its products risk becoming “niche premium products with low market share, like the Mac.”

 

According to our research, Apple has to appease not just its existing customers, but also those in China who make up a growing portion of the company’s revenue and who have been looking to rivals to stem their desire for larger devices. In fact, because Apple has failed to expand the display of its devices beyond the 4-inch limit, demand in China has been slowing. In launching a larger device, it would calm the “pent-up demand” in the country. Don’t forget that this large Asian country currently accounts for more than 15 percent of the company’s revenue. Hitting a home run in mainland China must be high on Apple’s priority list.

 

Taking the Debbie-Downer approach for Wall Street, one analyst group thinks Apple’s entire approach is slowly eroding its competitive streak — meaning arch-rival companies like Samsung are gaining traction. That said, Apple isn’t a small company. It has more than $150 billion in the bank, and could reinvest in its products even if sales collapses, but the fewer sales makes it difficult for the company to reinvest its profits into its products. Anyway Apple “remains a hardware company, having failed to evolve sufficiently towards services.” While Apple’s iTunes, software, and services division has increased in profits quarter-over-quarter, it’s still a fraction of the company’s income.

 

Yes, those services, such as the iTunes and App Stores, iCloud storage fees, and in-app purchases, continue to expand but have yet to make any significant headway into an already vast and expansive market.Photo:iGotOffer.com

Apple lets Bitcoin back onto the iPhone

Bitcoin believers should be happy as Apple has announced that the company was developing a new mobile payment system that could come out as soon as possible.

Apple approves now bitcoin wallet apps as it permits bitcoin wallets in its App Store. Before then, it had been a rocky ride for folks who wanted to receive and send bitcoins on their iPhones as in the past Apple dropped popular wallet apps such as Blockchain and Coinbase from the App Store, without even explaining the reasons.

CoinPocket is the first approved app which allows users to sell and buy bitcoins on their iPhone. It was built by Michael Enriquez, an independent software developer from Cleveland, who calls his app a bit of a “resume-builder.”

In spring 2014, Michael Enriquez wrote a Web-based version of CoinPocket that could operate with bitcoins on the iPhone. As soon as Apple announced that it would be OK with virtual currencies, the young developer decided to build a full-fledged iOS app, and he submitted CoinPocket for approval, getting the jump on much more popular wallet software. Ten days after Enriquez’s application the app was approved. It usually takes a few hours to get accepted after going into “in Review”, but this time it took a few days, so Apple seems to scrutinize more carefully Bitcoin matters. Enriquez had more than 2,000 downloads just in two first days, which is apparently a good sign for Bitcoin and IPhone enthusiasts.

Bitcoin adepts with iPhones will tell you that Apple blocked Bitcoin apps that allow users to send and receive Bitcoin in the pas (but for some odd reason, a wallet app from Blockchain managed to avoid getting bumped for years. With Blockchain, you could scan QR codes and easily send and receive Bitcoin via mobile. They say that members of the Bitcoin community would tell people to use the app but to keep quiet about it. But finally Apple kicked Blockchain with little explanation from Apple (removed from the App Store due to an unresolved issue). The situation has changed for the better for both IPhone and Bitcoin followers. Sell iPhone and sell bitcoins is since now just the same.

New iMac mid 2014

If you’re looking to replace your old iMac with something better, you may be in luck. Apple is planning to release an upgraded model for its all-in-one line of computers next week while lowering the prices of the previous machines currently on the market.

According to the website MacGeneration, these new and improved iMacs will have slightly faster processors and may include Thunderbolt 2 ports. Apple’s 27-inch iMac models will be available with a 3.3-GHz Core i5-4690 processor, a 3.5-GHz Core i5-4690 processor or a 3.6-GHz Core i7-4790 processor. Meanwhile, the 21.5-inch models will come with 3.0-GHz Core i5-4590 processors and 3.5-GHz Core i5-4790S processors. Overall, the chips in these new iMacs are expected to be about 100MHz than their predecessors.

This latest news comes right on the heels of the debut of Apple’s OS X Yosemite operating system, which offers improved iOS integration and an improved interface with translucent windows and new icons. The OS X Yosemite operating system will be available as a public beta in July.

In the past when Apple released a faster version of the iMac, they cut the prices of the current generation. That will most likely happen again, but how low the prices will go remains to be seen.

In the meantime, this could be the perfect opportunity to sell your current generation iMac if you are planning to upgrade. If you want to sell your iMac or any of your other old Apple devices, iGotOffer can take them off your hands and pay you what they’re worth. This can be a great way to save money towards an iMac upgrade, so contact us today for more information.

Earth Day

Earth Day

People are often at a loss when they find themselves with old computers, cell phones and other electronic devices. Electronics are seen as pretty disposable these days, especially when there’s always a new iPhone or iPad just around the corner, so chances are that you have at least one electronic device lying around that you don’t use anymore.

You may be tempted to just throw your old cell phones, laptops and tablets away. After all, you’re not using them anymore, right? Well, you should probably think twice before you do that. You may think that a tiny broken cell phone would be harmless if you threw it in the trash, but the truth is that many electronics contain materials such as cadmium, mercury, lead and nickel that can be harmful to people and the environment when they aren’t properly disposed of. In fact, throwing electronics out with the rest of your trash is illegal in many states.

Alternatives to the Trash

Since throwing old electronic devices in the trash is bad for the environment and illegal in some places, what’s the alternative? Many cities throughout the country have recycling programs that will take old computers and cell phones off your hands and recycle them or dispose of them safely. That’s usually the best way to get rid of older electronics, but what about newer devices? Things like iPads, iPhones and Mac Pros are expensive, and even if they’re broken people may still be reluctant to part with them without getting something back to offset the original cost. Fortunately, there are alternatives available. iGotOffer buys used and even broken iPads, iPhones and other Apple products at competitive prices. They can cover the costs of shipping, and you can even arrange from them to pick up your device if you are near their New York location. You can find out more about these services at iGotOffer.com.

No matter what you decide to do with your old electronics, remember that they should never simply be thrown away. Many devices contain materials that can be harmful to the environment, so think about either recycling your electronics or selling them if you think they could be refurbished or repaired.

iPad Microsoft  Office

Apple’s iPad is still the dominant tablet on the market, but it’s been facing some stiff competition from other products such as the Microsoft Surface Pro. The Surface Pro is certainly more powerful than the iPad, but it still seems to lack the appeal of Apple’s tablet. As powerful as the Surface Pro is, it is also much more expensive. It also has a less elegant design than the iPad Air, the display isn’t as sharp and vibrant and the speakers on the iPad are just a little more powerful. As much as the Microsoft faithful love their Surface Pros, the iPad just seems like the better machine overall.

 

There is only one area where the Microsoft Surface Pro outshines the iPad, and that’s in productivity. As a Microsoft product, the Surface Pro was always capable of running a version of Microsoft Office, which has been the most widely used software suite for years. The iPad didn’t have its own version of the iconic Office suite, and this has always held the tablet back in the eyes of many. However, that looks like it’s become a thing of the past, because Microsoft just released a version of Office designed for the iPad this past Thursday, ending what may have been the longest period of anticipation in the history of iPad apps.

 

If you’re familiar with the Microsoft Office suite (and who isn’t), you should know what to expect from the iPad version. It has almost all of the programs and features found in other recent versions, except everything seems to have been streamlined with the iPad’s operating system and display. As with other current versions of Office, all of your work is saved to the cloud-based Microsoft OneDrive storage account, which means that you will be able to easily access files using other devices. The one major downside to Microsoft Office for the iPad is that there is no option to print files directly from the device itself. On the other hand, accessing a Word document or spreadsheet created on your iPad with another machine capable of printing isn’t a difficult task.

 

Now that Microsoft Office is available for the iPad, perhaps now would be a good time to invest in a brand new iPad. Even if you already have a Microsoft Surface Pro, you can always sell it to iGotOffer when it comes time for a new tablet. iGotOffer offers free shipping and competitive prices for used or even broken devices, and it could be exactly what you need to help you afford a new iPad Air 2 or the iPad 6 when it comes out. For more information about how you can get paid for a used iPad or any other Apple device, contact us online at iGotOffer.com.
