Another North American Magic Box

Log in Over the past few years, GBA has published several articles on “magic boxes” — a type of combination appliance that functions as a ventilation system, heating system, and cooling system. Most recently, I wrote about the CERV, a magic box manufactured in Illinois. Now a Canadian manufacturer has come out with a magic box that resembles the CERV.The new device, the Boreal 12000, is manufactured by Minotair, a small company in Gatineau, Quebec. Like the CERV, the Minotair Boreal 12000 includes an air-source heat pump. All of the heat pump’s components, including both the condenser coil and the evaporator coil, are located indoors. Like a heat-recovery ventilator (HRV), the Minotair Boreal 12000 has four duct connections, including a fresh air duct that pulls outdoor air into the appliance and an exhaust duct that delivers stale air outdoors. During the winter, the exhaust air from the house passes over the heat pump’s evaporator coil, allowing the heat pump to scavenge some heat from the exhaust air. Since the condenser coil is located in the fresh-air duct, the Boreal 12000 delivers heat to the incoming ventilation air.A motorized damper adjusts the airflow paths depending on whether the unit is in ventilation mode or recirculation mode. During the summer, the heat pump removes heat and moisture from the incoming outdoor air stream and delivers heat to the exhaust air stream, thereby lowering the temperature and humidity level of the incoming ventilation air. The main purpose of the Minotair Boreal 12000 is to provide mechanical ventilation for a home in a way that pays close attention to the indoor humidity level. While the device appears capable of doing an excellent job of ventilation, it can also provide up to 9,400 Btu/h of space heating and up to 8,700 Btu/h of cooling.

DDoS Attacks As Social Protest

first_imgA Web Developer’s New Best Friend is the AI Wai… Tags:#Anonymous#ddos#hackers#privacy#security adam popescu Related Posts A new petition, organized by Anonymous, has been sent to the White House with the hopes of legitimizing DDoS attacks – those hacker-led techno-onslaughts that shut down Web sites.The petition basically asks that distributed denial of service, or DDoS attacks, be designated as legitimate forms of protest. This is quite a stretch considering the amount of damage these attacks do (just ask the Federal government, JP Morgan Chase, Bank of America and a host of others). And the petition authors want those jailed for DDoS immediately released and their records cleared.Fat chance, right?The writers of the petition say DDoS attacks are the “equivalent of repeatedly hitting the refresh button on a webpage… Instead of a group of people standing outside a building to occupy the area, they are having their computer occupy a website to slow (or deny) service of that particular website for a short time.”The petition needs 25,000 signatures by February 6 in order to trigger a White House response (as of Monday night, there were 5,420 signatories). Anything less than the required amount, and the White House can treat this like spam and junk it. While it’s not likely to be effective, launching a petition like this in the wake of the death of Aaron Swartz and the wave of newfound support for hacktivists, may be the best possible timing for the petition to gain supporters (another online petition entitled “Reform the Computer Fraud and Abuse Act” also attempts to catch the rising support for hactivism). Still, that doesn’t mean it’s going to get real traction. A glass-half-empty look at the petition could classify it as a naive, tongue-in-cheek attempt from the black hat world to justify their activities – likely doomed to failure. Chance Of Snow In Hell Today“There is no way in hell the White House will ever legalize DDoS,” said activist and Australian journalist Asher Wolf. Wolf believes the petition comes from the Anonymous Collective. Attempts at contacting Anonymous were not returned at time of publication. But this issue may not be as morally black-and-white as one mightl make it. Security expert Dan Kaminsky says that while he wouldn’t sign the petition, he thinks the attempt is far from silly or naive. Kaminsky indicated that while the petition may be misguided, the idea of creating legitimate forms of online protest in the heavily guarded online world are needed.“People are going to figure out how protest works in a system that has gotten very good at suppressing protest,” Kaminsky said. “I see where they’re coming from… I understand the desire.”The fundamental problem with DDoS, Kaminsky added, is the numbers disparity between those who perform the DDoS attacks and those targeted. Usually the culprits are small groups of people targeting large numbers of computers. So while many computers are affected, in terms of manpower the numbers of actual participants are low. Kaminsky believes that’s what makes DDoS a lesser form of protest than say physical people in the streets.  “What makes protest work is the visible human investment,” he said. “Five people in Guy Fawkes masks protesting Scientology makes an impact. Who cares how many computers are involved, they don’t have opinions… One hundred thousand people protesting is very different from making 100,000 computers [shut down].”Not All About Social ChangeJust when you’re ready to change your mind about the hacker collective and believe they’re about to bring the world positive change, they go and do something that would make even their staunchest supporter say: “Huh?”Last night, Anonymous took credit for hacking into several news organizations’ websites, including the Los Angeles Times, Slate and Vanity Fair – all to wish a very special happy birthday to a fellow hacker. One step forward, two steps back.How Will Anonymous And Friends Be Treated?While this petition will not likely make it to the White House’s to-do list, it reflects a sense of the growing power of Anonymous and similar groups. These organizations looking for new ways to expand power and be taken seriously in this fast-evolving online landscape.In the last few years, the Anonymous movement has gone from small hacker cells to mainstream in-person gatherings the world over, with thousands donning masks and pounding the pavement. If they can translate that sheer human power to the Web, they may become much more powerful. If and when that happens, governments may being to treat with them the way they do foreign principalities – or terrorists. Photo Courtesy Of Shutterstockcenter_img Why Tech Companies Need Simpler Terms of Servic… 8 Best WordPress Hosting Solutions on the Market Top Reasons to Go With Managed WordPress Hostinglast_img read more

Doing Some Things Some of the Time

first_imgOver time, your results match your effort. The more consistently you do something, the more consistent your results. The more sporadic your effort, the more unpredictable your results.Some people do some things some of the time. You can have some success by taking some of the necessary actions to reach some desired outcome some of the time. Occasionally you may even experience massive success. But those successes will be unpredictable, and you won’t ever generate predictable results. You also won’t produce your best results.There is power in routine. There is power in doing the same thing, in the same way, at the same time, over and over again. The results you produce from disciplined, consistent routines far exceed the results you produce when you only do things some of the time. Or when you do something different every time.Too many salespeople prospect sometimes. Because their efforts are inconsistent, so are their results. Their occasional work produces results from time to time, and that allows them to believe that what they are doing is working. It never allows them to produce the results of which they are capable. Prospecting produces the best results when you do it consistently.Too few salespeople plan for sales calls. When they do, it’s only because they have to make a call on a high value prospect. They feel good when they make these calls because they are prepared, but not good enough to do the work for every sales call they make. Every interaction with a client is worth investing the time necessary to make it a successful call for you and your dream client.Some sales organizations are also consistently inconsistent. They don’t have a rhythm of business. There aren’t consistent processes, meetings, or systems to generate consistent results. Every year they change without actually producing the benefits from all the things they put in place in prior years.Sometimes isn’t a good model. If an outcome is important, consistency is what will generate that result. Essential Reading!

They also bought souveniers for their loved ones back home.”I have come here to buy something for my wife. I will rather choose an Indian style saree or Salwar suit,” said a Kenyan athlete.Even the international zone which houses recreational facilities like cafe, stores, bar, restaurant, discotheques, games parlours and hair cut salon had a few visitors. Many others were trying to get confirmations of their departure tickets.Only about 5-6 players were seen practicing in the training area.The 12-day long sporting event featuring 17 sports disciplines like archery, cycling, gymnastics, swimming, boxing and shooting will conclude on Thursday.Security personnel also seemed to be in a slight relaxing mood as there were fewer visitors to come to the Village today unlike other day.last_img read more
