An ‘Insulating’ Paint Salesman Is Tripped Up By His Own Product

first_imgThere is no such thing as “insulating” paint, as I noted in an earlier blog. However, that fact hasn’t stopped paint dealers from promoting these worthless high-priced coatings to gullible customers.One former distributor of “insulating” paint is Alton King of Longmeadow, Mass. After setting up a company called Energy & Conservation Management Inc., King became a distributor of Super Therm, a paint manufactured by Superior Products International. The manufacturer claims that Super Therm (also spelled “Supertherm”) has an “R-19 equivalent rating” and “provides the same protection as 6 inches of fiberglass.”The manufacturer of Super Therm has been making outlandish claims for years. Back in March 2004, I wrote an article for Energy Design Update, “R-Value Scofflaws,” debunking a claim by Superior Products International that Super Therm “provides R-19 in 7 mil thickness.”Although the claim that a coat of Super Therm paint is equivalent to R-19 insulation is clearly false, Alton King apparently believed it. In fact, King was such a believer in the insulating value of Super Therm that he decided to use the paint to insulate his own home.In January 2001, King hired Richard McCullough to build him a new 7,291-square-foot home at 49 Memery Lane in Longmeadow, Mass. After the house was completed, the town assessed the home at $1,060,300.RELATED ARTICLE‘Insulating’ Paint Merchants Dupe Gullible HomeownersPodcast: Martin Holladay discusses “insulating” paint in a radio interviewThe builder hired a subcontractor, Paul Tetro of Dee Service, to design and install the home’s HVAC system.

Fire Knocks Out Tower at Concentrated Solar Plant

first_imgMore PR woesIvanpah has suffered a variety of public setbacks since it went online in 2014, including reports that birds flying into concentrated beams of sunlight were being killed. One report last year estimated 3,504 bird deaths per year could be attributed to the plant.The plant has not been able to produce as much electricity as its contracts required. Two of the units, under contract to Pacific Gas and Electric, are supposed to produce 640,000 megawatt-hours of electricity per year, according to The Wall Street Journal, but actually made about 45% of that in 2014 and 68% in 2015. The California Public Utilities Commission in March voted to give plant operators a year to correct the problem.BrightSource, one of three owners, said that performance has steadily improved since the project was completed, and that a “multi-year performance learning curve has always been assumed since the earliest stages of planning.”In an online statement titled “The top five things some media can’t seem to remember about Ivanpah,” BrightSource said that it “remains confident that Ivanpah will operate successfully” over its 30-year life. “It is designed specifically to minimize impacts on native ecosystems, and our comprehensive set of best practices positively address site selection, low-impact design, water usage, air quality and species protection,” the statement says. It adds that bird deaths have been exaggerated, and that unpredictable weather is partly to blame for lower-than-expected output. A fire last week damaged one of three towers at the huge Ivanpah solar thermal facility in the Mohave desert, but the real threat to the facility’s long-term relevance appears to be economics.The incident left metal pipes in steam-generating equipment near the top of the 459-foot tower scorched and melted, according to a report at Wired. The fire is one more PR headache for the world’s largest solar facility.The towers at Ivanpah are surrounded by 173,000 pairs of computer-controlled mirrors, each the size of a garage door, that focus sunlight on a boiler to produce steam and drive a generator. A misalignment of mirrors may have been the cause of the fire, the San Bernardino County Fire Department said, but NRG Energy, which operates the $2.2 billion plant, said it was too soon to tell. The Los Angeles Times said the fire was minor. A plant worker was able to put it out with a fire extinguisher.There was no immediate word on when the tower would be back online. A second tower is undergoing routine maintenance, so the fire on May 19 effectively brought the production of electricity to one-third of capacity. Concentrated solar can only get so much cheaper and won’t enjoy the same decline in operating costs as PV, suggested Adam Schultz, program manager at the UC Davis Energy Institute. “You’re not going to see the same thing with concentrated solar power plants because it’s mostly just a big steel and glass project.”Among other drawbacks, concentrated solar plants need a lot of land. Ivanpah is spread over 3,500 acres, while PV panels can be mounted on rooftops or on small tracts of land in whatever numbers make the most sense for the project.Ivanpah also is complex. Getting hundreds of thousands of mirrors to align correctly is a challenge that makes the plant difficult to run. A glitch can send sunlight slightly off course, as might have been the case with last week’s fire.“The sheer size of these plants make it easy to overlook one little flaw,” Tyler Ogden, an analyst at Lux Research, told Wired. Solar Thermal Plant Blamed for Bird DeathsIf a Solar Plant Uses Natural Gas, Is It Still Green?In Clash of Greens, a Case for Large-Scale Solar Surge in Renewables Remakes California’s Energy Landscapecenter_img Electricity from photovoltaics is cheaperA bigger threat to the plant is a financial one, according to the Wired story. When the plant was still on the drawing boards in 2007, Wired said, the cost of electricity from the facility would have been about the same as making it with photovoltaic (PV) panels. Since then, the cost of PV modules has plummeted. PV-generated electricity has come down to about 6 cents per kilowatt hour while the cost of power from concentrated solar plants like Ivanpah is 15 to 20 cents per kWh.

Laughing at the Frustrating and Embracing Quiet Moments

first_imgJayden Serck is a new military wife.  After graduating from college with a Human Development and Family Studies degree, she married Jordan, her high school sweetheart, who graduated from college a year earlier with a Bachelor of Science degree in Nursing.  When Jordan joined the Air Force with a direct commission they encountered multiple transitions in their young married life.  Jordan traveled from South Dakota to Alabama for training before they traveled together to their first duty station at Travis Air Force base in California.  Jayden is not new to military service as her mother served in the Army National Guard and her father is currently serving in the Air National Guard.  However, being a spouse of an active duty Service member is new.  In this blog Jayden shares her experience as they encounter a variety of transitions.  The LetterIt’s real.  It’s here.  When the letter came in the mail it was proof that Jordan (my husband) had been accepted to the US Air Force and the process had officially begun.  It was exciting and full of unknowns.  During this time, we quickly learned the “hurry up and wait” motto of the military!  There was so much to be done, yet each step required completion of a previous task in order to proceed.  At this point in our journey, we learned to not stress too much about anything.  Jordan was in close contact with his  recruiter and prepared for his first PT (Physical Training) test at MEPS (Military Entrance Processing Station).The SeparationJordan left our home in South Dakota to attend four weeks of commissioned officer training in Alabama.  We decided that I would not join him in Alabama so that I could continue working and make plans for our big move to Travis Air Force Base in California.  Whether it be basic training, commissioned officer training (aka COT), deployment, temporary assignment (aka TDY), or any other sort of event that causes spouses and families to be separated from their Service member, it is best to appreciate time alone and reflect on the reasons why the marriage and love is worthwhile and strengthening throughout this process.  Keeping busy is also HUGE (or “youge” as Donald Trump would say) for staying sane.  Picking up extra hours at work or spending time with friends and new acquaintances made the time fly for me.The past few months I’ve really been able to live out my New Year’s Resolution to the fullest (it’s possible!). In December 2015, I decided I needed to start saying “yes” when asked to do something, no matter how lazy I’d rather be.  By doing so, I have met so many new friends, changed my lifestyle and made wonderful memories.  For example,  I recently took a trip to Santa Clara with a family I’ve met just once to go to a FREE Kenny Chesney, Miranda Lambert, Old Dominion and Sam Hunt concert  (check our Vet Tix if you have not yet to see how).  I anticipated that this experience would be uncomfortable at first, but it was an opportunity I will probably never get again. I want to live my life to the fullest; regardless of whether the outcome of the experience is positive or negative.The Move & In-processingI found it extremely valuable to participate in Jordan’s graduation ceremony!  Going to Jordan’s graduation helped me visualize and understand what he had experienced the previous month.  Alabama was crazy humid and I give all of those officers props for staying disciplined in 100% humidity. After the graduation, everyone was kicked off Maxwell AFB and were on a timeline to get to their first duty station. We took advantage of this time! After being separated for a month, things fell back into place very quickly.  It was like being on a mini vacation. We were able to visit landmarks in 10 states and spent a night in Las Vegas on our way to California.We found that we spent a lot of money during the move.  We learned that waiting on housing can take months, and it is likely military families may need to sleep in hotels and temporary lodging for at least one month. A certain amount of these expenses are  reimbursed, however that can take a long time (it took about two months for our travel pay to come through) so budgeting is necessary! We’ve also learned that it is common for the LES (paystub) to be messed up after the member starts working too, so be sure to constantly be checking.Arriving on base was a relief, but was a high paced environment.  Jordan was thrown into trainings immediately, before spending 10 days  house hunting (we definitely utilized these too!). House hunting was easily the most stressful part of our PCS.  We felt we needed to get housing immediately and didn’t have a clue where to look.  We were incredibly fortunate to be offered on-base housing within three weeks of arriving on base and moved in two weeks after being offered the house.  That meant, we obviously well exceeded our 10 day allotment.  After putting down a non-refundable $200 deposit on an apartment, we didn’t even sweat the loss, knowing we’d have an additional 1000 square feet and live in a secured, safe neighborhood.Spouse EmploymentA lot of spouses choose to work, and a lot do not. Many stay home with their children or have in-home daycares (which they must set up through a base Human Resources; at Travis it is through NAF or nonappropriated funds).  Many spouses, like myself, choose to find a job as soon as possible. After looking at a lot of options on and off base, I found NAF hires for most of the amenities on base such as lodging, child development centers, and recreational buildings.  The process can go quick like it did for me (1-2 weeks) or take much longer (1-2 months – especially for childcare jobs that require FBI fingerprint results to be returned before starting). There are many HR offices on base though for GS jobs ( and AAFES jobs at the BX and commissary. My biggest piece of advice here is to really consider all of your options and choose a job that will make you happy rather than trying to get a job as fast as possible.Continuing our CommunityThe most helpful resources in terms of getting to know the area were spouses’ Facebook pages and both Jordan and my co-workers.  Within a few days, we had been invited to multiple gatherings and dinner parties by co-workers.  They let us know good and bad areas to live, and places in the area that are must sees. People are always flooding on and off the base, so going to any on-base events or parties that may be offered are crucial in establishing friendships and long-term happiness.I also decided to start a snail mail fund to keep in touch with family and friends back home. Social media is great, but it is so nice to send and receive little presents and letters to keep in touch. Skype is great, too, of course and holding ourselves to calling when we say we will has been important as well.Overall, our transition was very smooth and we are now happily settled in our California home and life!  We learned to laugh at the ridiculously frustrating things and embrace the quiet little moments. Whatever life brings our way, we will be together and are in a caring and helpful community full of people who closely relate to everything we are experiencing.last_img read more

Adobe Prelude: Organize, Log and Rough Cut

first_imgJump start your editing workflow with Adobe Prelude before moving to Premiere Pro or Final Cut Pro.Whether your an individual or a team, everyone is looking for ways to save time and work efficiently while creating the best work they can.  This is especially true in the video production business, where time is short and deadlines are always fast approaching.Prelude is a handy tool for video pros to ingest and organize your video footage.  Video producers and editing assistants can use Prelude to ingest, log, and create a simple rough cut edit in Prelude before handing off to the editor. Prelude can be used on-location on a laptop or older computer as it has lower system requirements than Premiere Pro.But Prelude is not just for Adobe Premiere Pro video editors.  If you also work with Final Cut Pro 7 or Final Cut Pro X (common for freelancers) you can export an XML file from Prelude to continue working in those apps.In this post we’ll explore logging, clip organization and creating a rough cut in Adobe Prelude.  Note, if you’re new to Prelude, check out my previous posts on ingesting in Prelude here and here.Get Organized With PreludeIt’s hard to be creative when you can’t find your footage! Getting organized at the beginning of the project will save you a lot of hair pulling later on.  To organize your clips in Adobe Prelude create bins, just as you would in Premiere Pro, Final Cut Pro or Avid Media Composer.Click the bin (folder) icon to create a new bin (highlighted in red below). Or right-click in the Project Window and select “New Bin”.Editing trivia break: If you are wondering why they are called bins and not folders, film hung in bins when editors were cutting film!Right Click Contextual Menu:Be aware that if a bin is selected and you create a bin, the bin will be created nested inside the previous bin.  In some instances you may want to have sub bins, it just depends on your workflow. Note, you can’t see icons of clips currently in the Project, but hopefully that is added in a future release.Logging: Subclips & Adding MarkersIn Prelude we can create subclips and add markers to save the editor time. Subclips let you break large clips into smaller, more manageable clips and can be better organized by topic or priority. Comments are useful to pass along notes to the Editor like “stabilize shot” and “fix white balance.”Double click on a clip in the Project to open it’s Timeline. To add a marker, press the appropriate number (1 for subclip, 2 for comment).Give your marker a name in the highlighted blue “Name” column. Use J,K,L to navigate the clip and set In & Outs with I & O like you would in an editing app.After adding your marker you’ll see an asterisk in the timeline, telling you you have unsaved changes. After you save a subclip, you will see the subclip in the Project.You can always name the marker later and add comments by clicking on it, and renaming it in the Marker Inspector.Creating a Rough Cut in PreludeIf you want to rough out an edit in Prelude, you’ll first need to click the Rough Cut icon (highlighted in red below) or use the shortcut Command + N (on a Mac) or CNTRL + N (on a PC).  Name and save the rough cut, and it appears in your project.  Click image for larger view.Open the timeline by double-clicking the rough cut in the project panel.You can now drag clips and subclips into the rough cut timeline, or right click on a clip and select “Append to Rough Cut”. The editing functionality is kept basic (no transitions or insert/overwrite), as Prelude is designed to roughly string together clips which is then handed to the editor.Send to Premiere Pro from PreludeIf you are running Premiere Pro and Prelude on the same machine you can send your Prelude project to Premiere.  Select the rough cut and the bins you want to send, right click and choose “Send to Premiere Pro”. Alternatively, you can use File> Send to Premiere Pro.If you have Premiere Pro already open, whatever you send from Prelude will be added to your current Premiere project.Export to Premiere Pro, FCP 7, & XIf Premiere Pro is on another machine or if you want to export Final Cut Pro XML,  use Export instead of Send To.Select your rough cut, clips and bins.  Then from the menu bar select File > Export (you can also use the shortcut Command + M on a Mac or CNTRL + M on a PC).  In the dialog box, set your Destination (hard drive or FTP), Project, and Media settings.  Then, click OK.If you are a Final Cut Pro X editor you will need the 7toX app  ($9.99) to convert from FCP 7 to FCP X xml.  Depending on your format you may also want to transcode to Pro Res if working in FCP.Markers & subclips are sent with the XML to Final Cut Pro 7 & X (terminology is different).  This is helpful, as freelancers often use various software depending on the job.

Comparing capacitive and inductive sensing for embedded applications

first_img Consider another use case employing proximity sensing. A vehicle detection system needs to monitor when another vehicle approaches within two meters and signal the driver on the dashboard or navigation panel. This functionality can be implement using inductive sensing. A hardware board containing a coil around the dash board can be designed around the four corners and center of the headlight areas (see Figure 2). Data from the inductive coils is collected by an inductive sensing controller such as the PSoC 4700S from Cypress. The controller would then analyze the data to determine the presence or absence of other cars in a four-meter vicinity around the vehicle.Figure 2: Using inductive sensing to determine vehicle proximity in an automotive application. (Source: Cypress Semiconductor) Capacitive sensing could also be used for vehicle proximity sensing. However, capacitive sensing is more sensitive to noise due to changes in the environment like rain and snow. Inductive sensing is rugged, environment-independent, and easy to design and develop from an engineering point of view. In addition, little tuning is required to achieve the desired closed loop for a particular application. Implementing Inductive Sensing In general, designing an inductive sensor is fairly straightforward (see Figure 3). A typical inductive sensor requires one or more inductive coils, as determined by the requirements of the application. The sensor needs to be interfaced to the controller using suitable drivers or controllers to be understood by the microcontroller. This interface can be implemented using external components. However, to reduce system design and manufacturing complexity, some inductive controllers integrate driver and converter circuitry to convert inductive sensor data into raw counts which can then be processed using suitable algorithms.Figure 3: Inductive Sensor Block Diagram (Source: Cypress Semiconductor) Figure 4 shows the design flow for a typical inductive sensing application. First, assess how sensitive the system needs to be. Sensitivity determines the coil size and its number of turns are decided. The application also impacts the shape of the coil. For example, a slider interface requires a series of squares or an elongated rectangle. The next step is to calculate the tank capacitor and the inductance based on the number of turns, spacing, width, and for larger image Figure 4. Design flow for a typical inductive sensing application. (Source: Cypress Semiconductor) In comparison, capacitive sensing requires measurement of the theoretical capacitance with the required dielectric constant. Then, during the layout, the designer must follow take strict layout guidelines like ground shielding, making sure sensor traces have equal length for a constant Cp, and so on. For more details, Capacitive Sensing Design Guide.Once these parameters are decided, the next step is to begin the mechanical design, specifically the overlay, also known as the metal target. An overlay comprises two materials whose specifications need to be decided: the metal target and the adhesive. The metal target material determines the amount of deflection and response. We recommend using an aluminum overlay for inductive sensing application over here because of its better deflection and response.  For button applications, a higher Newton force on the overlay causes deflection throughout the overlay, leading to undesirable false triggering throughout the coils. For this use case, the user should only be able to press the buttons just enough to generate feedback. Pressing the overlay harder can even deform the overlay.Once all these things are intact, the board is designed and fabricated. The advantage of using a design environment, such as PSoC Creator IDE, is that it can help developers accelerate design of a user-friendly inductive sensing tuner graphical user interface.Both capacitive and inductive sensing enable developers to build intuitive, touch-based user interfaces to make their products more intuitive and easier to use. Because of its versatility, capacitive sensing has become the technology of choice in a great many applications. However, for applications where water tolerance is required, inductive sensing provides a robust and cost-effective alternative.Ronak Desai is a system engineering manager at Cypress. He is responsible for the development of development kits and hardware design. He has 18+ years of experience in the embedded industry, including the design and development of embedded products and set-top box applications.

First implemented using resistive sensing technology, touch sensing had to overcome many challenges, including low sensitivity, false triggering, and short operating life. This created an opportunity for touch sensing using capacitive sensing.Capacitive sensing has proven to be robust in many environmental use cases. However, as with any technology, capacitive sensing comes with its own challenges. As these challenges tend to application-specific, inductive sensing technology has risen to fill in the gaps.In this article, we will be discussing capacitive sensing for embedded applications and how it can be used in various applications. We will then explore the use of inductive sensing in embedded products and why inductive sensing is preferred over capacitive sensing in some use cases. Finally, we will compare the advantages of inductive sensing over capacitive sensing in these applications.Capacitive Sensing Capacitive sensing has been used primarily in two different forms: self-capacitance and mutual-capacitance. In self-capacitance mode, the net capacitance due to a finger touch and board capacitance (including PCB traces and PCB materials like FR4, which has more capacitance compared to Flex one) is additive. Self-capacitance mode is useful in general touch application like buttons for touch-and-respond applications. In contrast, mutual capacitance is well suited for applications involving more complex sensing such as gestures, multi-touch, and sliders.Mutual capacitance sensing utilizes two different lines: TX (Transmitter) and RX (Receiver). TX sends a PWM signal with respect to GND the digital system supply, VDDD . RX detects the amount of charge received on the RX electrode.One of the drawbacks of capacitive sensing is that it cannot operate underwater. It also requires relatively strict design guidelines to be followed for error-free operation. Capacitive sensing performance is also impacted by nearby LEDs and power lines on PCBs. Implementing auto-tuning with variation in trace capacitance, variation in capacitive sensing buttons, and different slider sizes and shapes also require different designs. Implementing capacitive sensing with thicker glass material (display glass) and meeting capacitive sensor sensitivity with these types of materials are additional implementation challenges in Industrial applications.Inductive Sensing Inductive sensing enables touch technology in applications involving metal-over-touch use cases such as in automotive, industrial, and many embedded and IoT applications. Inductive sensing is based on the principle of electromagnetic coupling, between a coil and the target. When a metal target comes closer to the coil, its magnetic field is obstructed and it passes through the metal target before coupling to its origin. This phenomenon causes some energy to get transferred to the metal target in the form of an eddy current that causes a circular magnetic field. This eddy current induces a reverse magnetic field, in turn leading to a reduction in inductance. A capacitor is added in parallel to the coil to create an LC tank circuit. As the inductance drops, the frequency shifts upward, changing the amplitude throughout.With the removal of a dielectric from the sensor, compared to a capacitive sensor, inductive sensing is able to operate reliably in the presence of water. Thus, inductive sensing brings touch sensing to a wide range of applications that involve liquids such as underwater equipment, flow meters, RPM detection, medical instruments, and many others. Inductive sensing also supports biomedical applications. In general, inductive sensing enables replacement of mechanical switches and proximity sensing of metal objects. For example, in automotive applications, inductive sensing can be used to replace mechanical handles as well as detect car proximity. Some of these examples will be discussed in detail below.Currently, the primary design challenge for implementing inductive sensing is designing coils with 100% production yield where inductive trace spacing is very narrow, such as using 4 mils spacing. There is also the consideration of meeting inductive values with variations in PCB laminate materials.Use Cases for Inductive Sensing and Capacitive Sensing Capacitive sensing is undeniably useful in a great many applications. However, for certain use cases, inductive sensing offers greater reliability. Consider the use case of a Bluetooth speaker that needs to be water resistant and is intended for use in up to two feet of water for half an hour. This use case requires more than just that the product is functional underwater. It also requires that the user can adjust the speaker in these circumstances. Such operation needs to be simple, consistent, and reliable, even in the presence of water.With capacitive sensing, such operation is partially possible using mutual capacitive sensing employing complex shielding techniques. However, the device would offer a less than ideal use experience. For example, there would be inconsistent responsiveness from the touch interface and it would operate differently than it does when it is used out of water due to changes in the dielectric introduced by the presence of water.For this application, metal-over-touch using inductive sensing would provide a consistent and reliable user performance (see Figure 1). Alternatively, a mechanical button and/or dial could be used. However, a mechanical interface is costly compared to a coil printed on a PCB and connected to a few passive components. Additionally, a mechanical button can break or fail, providing a much shorter useable lifespan than an inductive button would.Figure 1: The architecture of a water-resistant Bluetooth speaker using inductive sensing.

Academy Awards retains PricewaterhouseCoopers despite Best Picture mixup

first_img Facebook Advertisement Advertisement Advertisement Login/Register With: Twitter LOS ANGELES –  PwC accountants won’t be allowed to have their cellphones backstage during future Oscar telecasts.Film academy president Cheryl Boone Isaacs sent an email to academy members Wednesday detailing the new protocols for announcing Oscar winners developed after the best-picture flub at last month’s Academy Awards. Academy of Motion Picture Arts and Sciences spokeswoman Teni Melidonian confirmed the authenticity of the email.The academy’s Board of Governors discussed its ongoing relationship with PwC, formerly known as PricewaterhouseCoopers, and established the new controls at a meeting Tuesday night. Besides banning cellphones, the academy is adding a third balloting partner to the telecast, and bringing in PwC’s U.S. chairman to provide oversight. PwC, which has handled Oscar balloting and other academy business for 83 years, has claimed responsibility for the biggest mistake in Oscar history. Balloting partner Brian Cullinan tweeted a photo of Emma Stone backstage moments before handing presenters Warren Beatty and Faye Dunaway the wrong envelope for best picture. They announced “La La Land” as the winner, though “Moonlight” actually won.Boone Isaacs blamed Cullinan’s distraction for the error. PwC said that both he and partner Martha Ruiz failed to follow established protocols that night and did not act quickly enough to correct the error.Traditionally, two PwC partners have overseen Oscar balloting and are the only two people who know the winners before they are announced live onstage. They’re stationed on opposite sides of the Dolby Theatre stage, each with an identical set of winners’ envelopes for the show’s 24 categories.Boone Isaacs said in her email Wednesday that a third balloting partner with knowledge of the winners will sit with the telecast director going forward. Balloting partners will also be required to participate in Oscar rehearsals, she said.She called the 89th Academy Awards “the most extraordinary and memorable Oscars ceremony in decades” and said that academy officials have been working since then to develop the new protocols adopted Tuesday.

Honduras UN sends team to examine human rights violations after coup

16 October 2009The United Nations human rights chief is sending a team to Honduras on Sunday for a three-week official visit to examine violations of rights in the wake of the coup d’état in the Central American country in June. Navi Pillay, the High Commissioner for Human Rights, issued a statement today from Geneva in which she said the mission would seek the views of all parties in Honduras during its visit, which is scheduled to run until 7 November.Earlier this month the UN Human Rights Council formally asked Ms. Pillay to present a comprehensive report on violations in Honduras since the coup on 28 June, when President José Manuel Zelaya was ousted. That report is expected to be delivered by next March.Ms. Pillay, Secretary-General Ban Ki-moon and other UN officials, as well as the General Assembly, have all expressed concern about the situation in Honduras.

UN panel examines strategies against global drug abuse

A United Nations expert panel is examining the interaction between supply and demand strategies against the global drug abuse problem during its two-week session, which opened today in Vienna.The International Narcotics Control Board (INCB), the body monitoring worldwide drug abuse and trafficking, is also set to review a number of other related issues and developments, including the results of missions and technical visits the experts carried out in Indonesia, Portugal, Thailand and Timor-Leste, to obtain first-hand information on national drug control initiatives and on the implementation of the international drug control treaties in those countries.During its eightieth session, set to run through 28 May, the Board will also review the extent to which the Governments of Egypt, Jamaica, Pakistan, Ukraine and Serbia and Montenegro have implemented recommendations made to them, pursuant to respective missions carried out by the experts during 2001.The INCB, an independent body of 13 international experts, issues an annual report usually in late February on its findings in the field of worldwide drug abuse and trafficking, which also devotes special attention to a specific drug-related issue in its lead chapter.The Vienna-based INCB is an independent body established by the 1961 Single Convention on Narcotic Drugs to monitor Governments’ compliance with the international drug control treaties. Its members are elected by the UN Economic and Social Council (ECOSOC) to serve in their individual capacities for a term of five years. read more

Countries focus on concrete solutions to build new UNbacked global climate accord

“Countries discussed concrete solutions to speed up and scale up action,” said Christiana Figueres, Executive Secretary of the United Nations Framework Convention on Climate Change (UNFCCC), following the international negotiation panel in Bonn, Germany.She said that the representatives also discussed how to construct a transparent, measurable, verifiable agreement that gets the best out of all countries. “And they are committed to sticking to their own timetable.” The task of the UNFCCC’s Ad Hoc Working Group on the Durban Platform for Enhanced Action (ADP) is to negotiate a new, universal climate agreement by 2015, to come into force from 2020, and to find ways to increase current inadequate global ambition to address human-generated climate change before 2020.Ms. Figueres reminded governments during the meeting that “while they are on track to meet the milestones they have set themselves, they are not yet on track to meet the demands of science.”During this week of meetings, the second since annual high-level talks were held in Doha last year, Governments agreed that climate change needs to be addressed by all groups working together – from international organizations to the private sector – and with support from the highest political level, UNFCCC said in a news release.Participants also agreed that there are many opportunities to scale up existing mitigation actions, notably with the help of renewable energy, and that there is a need to build up sufficient financial means to implement action, among other proposals.The outcomes of this week’s meeting, and the next ADP meeting to be held in June, will be part of the agenda for the 19th Conference of the Parties to the UN Framework Convention on Climate Change (COP-19) this November in Warsaw, Poland.The ADP co-chairs, Jayant Moreshver Mauskar and Harald Dovland, said in a joint statement that this week’s discussions “are making progress, but we have limited time… and therefore need to continue and accelerate our efforts.” As representatives wrapped up in Bonn, the UN World Meteorological Organisation (WMO) confirmed that 2012 was the ninth warmest year on record.The global average temperature in 2012 was 0.45 degrees Celsius higher than the 1961-1990 average of 14 degrees, according to WMO’s ‘Statement on the Status of the Global Climate’ released on 2 May. The statement also confirms that 2012 was the 27th consecutive year with an above-average global temperature.“Although the rate of warming varies from year to year due to natural variability caused by the El Niño cycle, volcanic eruptions and other phenomena, the sustained warming of the lower atmosphere is a worrisome sign,” said WMO Secretary-General Michel Jarraud. “The continued upward trend in atmospheric concentrations of greenhouse gases and the consequent increased radiative forcing of the Earth’s atmosphere confirm that the warming will continue,” he said.The warming trend is responsible for record levels of ice thaw in the Arctic and extreme weather, including droughts and tropical cyclones, Mr. Jarraud said. “Natural climate variability has always resulted in such extremes, but the physical characteristics of extreme weather and climate events are being increasingly shaped by climate change,” he added.Europe is warming faster than many other parts of the world, according to figures from the UN Office for Disaster Risk Reduction (UNISDR). According to a statement the office today released, southern and central Europe is seeing more frequent heat waves, forest fires and droughts. While the northern and north-eastern Europe is projected to get more precipitation and flooding. In this context, the Special Representative of the Secretary-General for Disaster Risk Reduction and head of UNISDR, Margareta Wahlström, today welcomed the European Union’s newly announced strategy on adaptation to climate change.“The adoption of this new strategy is a major incentive for European states to step up their efforts for disaster risk reduction and climate change adaptation,” Ms. Wahlström said in a news release from Geneva.“Urban resilience is especially important across the region given that 75 per cent of the population live in urban areas which can be exposed to heat waves, flooding or rising sea levels.”The EU estimates that the minimum cost of not adapting to climate change would reach $131 billion a year by 2020 and $328 billion a year by 2050 for the whole EU. Ensuring environmental sustainability is one of the eight Millennium Development Goals (MDGs), anti-poverty targets world leaders have pledged to achieve by 2015. The UN General Assembly is scheduled to hold a thematic debate this month in New York to focus on climate change, green energy and sustainability. In addition, Secretary-General Ban Ki-moon wants the world to reach universal access to modern energy services by 2030 as part of his Sustainable Energy for All Initiative. read more

UN warns against inciting hatred after Ugandan newspaper publishes names of gays

A Ugandan tabloid on Tuesday named the country’s “200 top homosexuals,” a day after President Yoweri Museveni signed the Anti-Homosexuality Act into law, criminalizing and imposing life imprisonment for homosexuality, same-sex marriage and “aggravated homosexuality.”“The publication by a newspaper in Uganda of the names and photos of people it claims are homosexual not only violates the right to privacy, it also demonstrates the very real danger that the new anti-homosexuality law will encourage acts of violence and harassment against lesbian, gay, bisexual and transgender people,” said a spokesperson for the Office of the UN High Commissioner for Human Rights (OHCHR).Cécile Pouilly recalled that the High Court of Uganda has previously ruled that publishing such lists amounts to a violation of the rights to dignity and privacy protected by the Ugandan Constitution. “We reiterate that media organisations should refrain from fuelling hatred and attacks on the basis of sexual orientation,” stated Ms. Pouilly.“We further reiterate our call upon the Ugandan authorities to take urgent steps to protect all persons from discrimination and violence regardless of their sexual orientation or gender identity.” OHCHR urged the authorities to review the criminal legal provisions targeting lesbian, gay, bisexual and transgender people and make sure that attacks against them are investigated, and alleged perpetrators prosecuted. Both Secretary-General Ban Ki-moon and High Commissioner for Human Rights Navi Pillay spoken out against the new law and urged Uganda to repeal it. read more

Geekcom interview Jailbreak hero Jay Freeman you know Saurik

first_imgIt may seem strange that one of the biggest names in the iOS jailbreak community was speaking at the Big Android BBQ 2013, but after spending a few minutes talking to him it couldn’t be more clear that Jay Freeman is simply a fan of all things mobile.I had exactly one question for the man known globally as Saurik: “How do you get to a position where your name is synonymous with jailbreaking an iPhone?” As it turns out, Jay wasn’t a fan of Apple or the iPhone when the original first launched in 2007. The iPhone 2G wasn’t a good phone, but it was a fun, new experience and at the time it had the best browser on a mobile device. For someone with a Nokia candy bar phone, like Freeman, there was very little appeal. Despite pleading from his employer at the time, who very much wanted the whole office to be running Apple’s new handheld, Freeman remained unimpressed with the experience being offered by this first generation.Apple finally got Freeman’s attention when a handful of eager developers had created Installer, an app that made it possible for users to load apps that weren’t made by Apple onto the phone. Finally, the opportunity was there for people like Saurik to simply write their own features and fix whatever was perceived as broken. This was the push he needed in order to pick up an iPhone — within a day he had started interacting with the jailbreak community and trying to see where he could fit in.Unfortunately, Installer didn’t really fit Freeman’s needs. Most of what he was interested in meant not using Objective C, the language all of iOS was written in. To solve this he released JOCstrap, which allowed him to use Java in this environment. The install process was dependent on things being installed in a very specific order, and if you went out of that order there were problems. Then Saurik implemented an APT-style install tool that made sure you had these dependencies, and made the installer nice and easy. All that was missing was a UI, which users assured him was important. What happened next was the beginning of what most people now know as “Cydia”.Support for Installer by the original creator waned, which eventually led to it being woven into Cydia. Desire for Cydia grew significantly, and was even seen as its own platform before too long. By the time iOS 2 rolled around, Freeman had become not only one of the primary maintainers for these highly desired features, but was actively participating in the jailbreak process. From that point, he became involved in many other projects. Saurik is well known for Substrate on iOS and eventually Android, as well as maintaining HTC G1 user mailing lists and actively contributing to other operating systems.Jailbreaking is in an odd place right now, as we all wait for an iOS 7 jailbreak to be released. There’s no doubt that it is on the way and, if anything, iOS 7 opens a lot of interesting new doors. With many of the iOS updates, there has been a general buzz cycle surrounding the future of jailbreaking. First there’s a general sense of amusement that Apple has borrowed some ideas from the jailbreak community. Next, there’s a sense that jailbreaking is dead thanks to Apple’s clever new security measure. Finally, there’s the next jailbreak and the exploration of new opportunities. With tools like Control Center and Notification Center, Freeman believes that many jailbreakers will look at this and work on things to improve and add.As for details regarding the current state of affaies, Saurik made it clear that an iOS 7 jailbreak is absolutely on the way. The first steps have been accomplished, but now there jailbreak team is working hard on getting it working flawlessly every time. There’s no hard date, obviously, but it seems likely we’ll all be jailbreaking iOS again within the next two months.Cydia is more than ready, according to Freeman, with support for 64-bit support already ready to go. Despite an air of concern regarding security on iOS 7 after it has been jailbroken, Freeman doesn’t think it will cause as many problems as others may think. In fact, Jay seemed to think that access to things like TouchID would end up being more secure after developers have the opportunity to see how it works and makes sure it is being used correctly.last_img read more

ONeill focuses on the positives

first_imgDespite being relegated in the UEFA Nations League, Michael O’Neill is optimistic his Northen Ireland side is improving.Northern Ireland have failed to win a single point from their opening three matches in Group B3 and will be relegated to Group C when the Nations League returns, and Michael O’Neill knows that.Bosnia and Herzegovina are expected to win the group, with Austria in second place, but O’Neill feels they are improving as they try to focus on next year’s Euro 2020 qualifiers.“We played the other night with a starting line-up of five core players and six who are in single figures in terms of caps – Gavin Whyte, Liam Boyce, George Saville, Jamal Lewis, Michael Smith and the goalkeeper [Bailey Peacock-Farrell],” O’Neill told Sky Sports.The Netherlands have a walk in the park in Estonia’s pitch Tomás Pavel Ibarra Meda – September 9, 2019 With a stellar performance from Ryan Babel, the Netherlands won their second consecutive UEFA Euro Qualifier against Estonia.After the impressive performance they offered in…“We’re progressing, those boys are stepping up in international football and playing against a lot more experienced players.“I’ve been delighted with how the players have come in. We’ve got good competition for places in a lot of areas on the pitch, at times we haven’t had that.“So despite the fact the three games have gone against us, we were disappointed to lose the games but I’m not devastated or despondent.”last_img read more
