Get your sleeping bags ready – it’s time to ‘Sleep Out for Simon’ this October

first_imgNorth West Simon Community Annual Sleep Out is taking place on Friday, October 4th in Letterkenny’s Market Square.The event is an excellent opportunity for the Community of Donegal to come together to take their ‘Step for Simon’.The Annual Sleep Out helps to create much-needed awareness of the North West Simon Community and raise vital funds in order to prevent and resolve homelessness across the region. A spokesperson from North West Simon Community said: “It is only with the support of people like you, that we can continue to close the door on homelessness in the North West. We would like to sincerely thank the people from Donegal, Leitrim and Sligo for your generosity and solidarity and for the positive impact that you have made on people’s lives locally.”North West Simon Community also thanked all those who have already signed up to take part to include: AIB Letterkenny, United Health Care, Food for Thought, Buncrana, Crana Stables, Buncrana, Menarys, Greenes Shoes and the many individuals who will swap their beds for sleeping bags for one night only, in solidarity for those who are homeless or at risk of becoming homeless.Get your sleeping bags ready – it’s time to ‘Sleep Out for Simon’ this October was last modified: September 29th, 2019 by Shaun KeenanShare this:Click to share on Facebook (Opens in new window)Click to share on Twitter (Opens in new window)Click to share on LinkedIn (Opens in new window)Click to share on Reddit (Opens in new window)Click to share on Pocket (Opens in new window)Click to share on Telegram (Opens in new window)Click to share on WhatsApp (Opens in new window)Click to share on Skype (Opens in new window)Click to print (Opens in new window) Tags:North West Simonlast_img read more

To recharge or not to recharge: a battery of IoT questions

first_imgTop Reasons to Go With Managed WordPress Hosting Well, we technologists pretty much have that Internets thing solved. That series of tubes works pretty well. So well in fact that the carriers are busying themselves trying to bring Gigabit to everybody, though nobody really knows what they’re going to do with it (but we all want to be in one of those special cities). I think we got bored. And you know what happens when a bunch of technologists gets bored, we look for another hard problem to solve.Enter IoT, the Internet of Things. We realized that the Internet, with all of its virtual technology and its climate-controlled data centers, still hadn’t conquered what really matters to all of us – the world we interact with every day – the real world. Now, there’s a set of challenges that’ll keep us technologists engaged for at least another decade.I suggest the primary real-world challenge with the Internet of Things isn’t rooted in inter-networking at all, but with how powering the Things affects inter-networking and software programming, specifically in wireless situations.What do batteries have to do with IoT?We see powering in the world of Consumer IoT often in the form of rechargeable batteries. The iPhone charges for a few hours a day and is able to communicate via TCP/IP protocols over Cellular and Wi-Fi. That doesn’t seem to have changed the networking or software programming approaches too drastically. The Fitbit charges for a few minutes a day and communicates via Bluetooth with another mobile device. There we see a more drastic impact on the networking and software programming models.Daniel Barnes, Director of Product Management, SynapseBut what if I told you the battery had to last for one month without recharge or replacement? How about six months, two years, five years? Well, that’s insane, who would demand a wearable that lasted that long without a recharge?Consider these very real Industrial IoT applications: monitoring field and pest conditions in almond orchards, monitoring cows for sickness, a factory air compressor retrofit for predictive maintenance, over-the-top services such as crane monitoring, motor performance monitoring, or fire extinguisher monitoring. In each of these cases, the Thing is placed into the environment with the expectation of lasting longer than six months (some cases as long as five years) without service or connected power.As an aside, the over-the-top services as a business model is quite interesting. These are traditional product companies that make cranes, motors, fire extinguishers, etc. They have decided to make their products smart and connected to gather additional service revenue or to develop closer relationships with their customers. But they want to continue installing their products without interfering with the existing infrastructure. This alone represents a whole category of Things in the Industrial arena that may need to operate with long battery life.How do you make a battery last that long?You buy a REALLY big battery.That certainly is one way, but often not very practical nor is it cost effective. A more engineered approach boils down to three things:1) Use a low-power processor that has advanced sleep controls.2) Use a low-power RF technology that allows precise control of TX/RX utilization time.3) Control the power utilization of sensor and actuator peripherals.In other words, wake up long enough to read a sensor and send the information and then shut everything back down in as low-power mode as possible. It’s all about managing the power duty-cycle.What are the tradeoffs?Of course, the number one rule of engineering is that to get something you want, you have to give something else up. There are always tradeoffs – in this case trading traditional networking and software programming for a long battery life.Wi-Fi and TCP/IP don’t really help you control the power duty-cycle very well. Wi-Fi takes RF time to lock onto an Access Point. TCP requires a connection handshake before sending data and the overhead of the protocol to make it reliable. All of this costs valuable RF and processor time in the power duty-cycle. It’s time not spent on transmitting data, but on establishing the connection and maintaining reliability. You might consider UDP as an alternative, but it still has excessive overhead and the reliability is now left up to a higher layer where you often lose even more efficiency and introduce more complexity into your application. Some alternative networking approaches to shortening the “ON” duty-cycle include:Fire and forget (if reliability isn’t a big issue, it’s the lowest power option) Time synchronized transmit (to avoid collisions)A backbone of powered repeaters to relay messages (reliability between battery-operated nodes and powered nodes takes less time)These and others are all non-traditional networking schemes, meaning that others schemes have to be employed to ensure reliability. The good news is that there are emerging standards at the physical, link and network layers for managing these things, but they can’t be expected to work the same way as the networking that we’ve come to appreciate. There will be additional tools and algorithms necessary to collect data reliably.Just to add one more level of complexity, traditional OSs don’t support the rapid sleep/wake cycles necessary to conserve this type of power, nor will they work with the limited RAM & flash typical to these constrained processors. The decision-making logic on the Thing will be embedded software and largely event-driven: a programming paradigm traditional IT developers are not familiar with.So the bottom line here is that Industrial IoT will require a significant portion of Things to have batteries and these batteries will need to last for such a long time that reliable networking and programming will require rare expertise.The problem isn’t really how to power an IoT Things Platform, but that an IoT Things Platform ought to make it easy to achieve long battery life.

Is Muguruza heir to Williams sisters?

first_imgEthel Booba on hotel’s clarification that ‘kikiam’ is ‘chicken sausage’: ‘Kung di pa pansinin, baka isipin nila ok lang’ Acaylar ‘not satisfied’ as PH sweeps Macau in tuneup Add in Muguruza’s bold, aggressive playing style and affinity for the big stage, and she certainly looks like someone who could keep doing what she wants to do more than anything: win major championships.That matters more to her than where she is in the rankings, for example. She entered Wimbledon at No. 15, and will rise to No. 5 on Monday.Her career-best is No. 2, but that doesn’t seem to concern Muguruza all that much.“I don’t know what it feels to be No. 1. Hopefully one day I can – and then I (can) compare,” she said. “But for now, I’d rather be No. 10 (and) win Grand Slams, than be No. 1.”The key, she and others agree, will be finding more consistency. Saturday’s final against the older Williams was Muguruza’s first since the 2016 French Open.ADVERTISEMENT Church, environmentalists ask DENR to revoke ECC of Quezon province coal plant So she attached that hard-to-earn pin to her white zippered jacket, just over her heart, and fiddled with the thing while speaking to a small group of reporters Saturday evening.Muguruza noted that after losing in the 2015 Wimbledon final to Williams’ sister, Serena, she didn’t get the same treatment, of course: Runners-up don’t get the membership or its privileges.FEATURED STORIESSPORTSSEA Games: Biñan football stadium stands out in preparedness, completionSPORTSPrivate companies step in to help SEA Games hostingSPORTSWin or don’t eat: the Philippines’ poverty-driven, world-beating pool stars“It’s all or nothing,” Muguruza said. “So I’m like, ‘Whew, this year, I finally did it’.”This 7-5, 6-0 victory over Venus, combined with Muguruza’s win against Serena in last year’s French Open final, made the 23-year-old Spaniard the only woman to defeat each Williams sister in a Grand Slam title match. That alone marks her as a likely, and worthy, heir to the two women who changed their sport. Don’t miss out on the latest news and information.

Her first anywhere.To establish her place among the truly elite, she’ll need to more frequently summon the power and precision that she has managed to find on the most stressful occasions.“Hopefully she can stay a little bit more steady,” said Conchita Martinez, the Spanish Fed Cup and Davis Cup captain who worked with Muguruza during Wimbledon because her regular coach, Sam Sumyk, took time off for the birth of his child.“The key is to continue routines, continue to work hard,” Martinez said. “And to focus in every tournament you play is important.”Also worth keeping an eye on now: How Muguruza handles the aftermath of this latest triumph.She acknowledged that she found it burdensome to deal with the expectations that came with her first major championship. That was one factor in her results since, including only a 23-13 record this season entering Wimbledon.“It’s just hard, when you’re playing very good and you want to keep that, and maybe it doesn’t happen. You feel like, ‘Why (can’t I) play that good every week?” she said.At Roland Garros last month, Muguruza lost in the fourth round, then got choked up during her post-match news conference, saying she was happy to leave behind all the questions about the pressures of trying to defend that title.“I’m going to have a similar problem now, which is a good problem to have,” Muguruza said Saturday. “I just changed (the) page really fast. I was sad for a few days. But I’m like, ‘Just forget about it.’ … And that’s it. And I forgot.”The challenge is to remember how to play more frequently the way she did for those two special weeks in Paris two years ago, and these two special weeks in London this year. If she can do that, there’s no telling how many of these things she can win.Sports Related Videospowered by AdSparcRead Next Lacson: SEA Games fund put in foundation like ‘Napoles case’ View commentslast_img read more
