Serial real-time clock calibration
ST launched the world's first factory calibration of serial real-time clock (RTC) chips, due to omitted time-consuming calibration step, the use of these products, customers can simplify the assembly and testing operations. New Real-Time Clock M41T83 and M41T93 crystal package using built-in advance about the calibration accuracy of 5ppm, clock and date for the user equipment has brought new precision timing. Using a one-time programmable (OTP) register, ST can be tested in the factory during the fine-tuning on-chip 32.768 kHz oscillator internal load capacitance to ensure that these products a month time accuracy within 12 seconds. In addition to serial interfaces, these two new products share the same standards. M41T83 includes a 400 kHz I2C interface, while the M41T93 using 10 MHz SPI bus interface, is the world's first to run at speeds up to 10 MHz of real-time clock chip. These two new products, the first time introduced a series of advanced features, including analog calibration, a programmable auto-reload counter / timer and two alarms. In addition to the factory-programmed register, this product has also added a two analog calibration register, the user can reach through the register before the factory calibration settings. This feature is beneficial to adjust the ambient temperature because of errors caused by stray capacitance on the board or amend the accuracy of the impact of the time. Crystal-free QFN16 packages, the applications also need to register the new. Oscillator adjustment immediately in the test signal output to provide users with real-time Feedback adjustment. Auto-reload counter / timer with four user-selectable clock source of a complementary work to generate timing waveforms and provide periodic interrupt signal processors. Two programmable alarm pin through the two independent output signals in order to meet the needs of multiple applications to remind time. Both products include an on-board precision voltage reference tubes, automatically switch to standby power circuit a precise definition of the threshold pressure. This two-chip back-up supply current as low as 450nA (typical value), especially suitable for back-up power supply for capacitor applications, as well as the battery as a standby power products, in addition, as a result of the use of low-power manufacturing process, the minimum under 1.8V able to ensure precise timing. Built-in battery back-up monitor power supply voltage is responsible for inspection, when the need to replace the battery signal when prompted. Other features include 12 bytes of NVRAM and an oscillator failure detection circuit. If the oscillator pulse signals the loss of more than 3, oscillator failure detection circuit will be prompted to set up a bit to back-up power supply voltage may be too low, which may affect the accuracy of the time. In a back-up power supply for the capacitor applications, under-voltage during the regular session happen. Chip also integrates a programmable square-wave signal generator and a watchdog. When the supply voltage VCC disconnected, the chip will automatically transfer back-up power, to generate a 200ms power is restored after the reset signal exists. The power-on reset / low voltage detection for design engineers to save an independent board reset IC. Switching threshold voltage reset circuit and there are three voltage values (nominal 2.93V, 2.63V and 2.32V), when ordering products are clearly defined model. In addition to pre-calibration of the package outside the built-in crystal oscillator, M41T83 and M41T93 also using ST's low-cost space-saving 4mm x 4mm QFN16 package, and supporting the use of an external crystal oscillator. For the needs of mid-level real-time clock function of the low-end products and want the application of low cost, M41T83 product M41T82 Jane is a very good low-cost solutions.

China's exports plummet
The nation's spending on fixed assets such as roads, bridges and new plants grew 30.5 percent in the first four months from a year earlier. That compares with a 28.6 percent surge in the first quarter, the National Bureau of Statistics said Tuesday.
Meanwhile, exports dropped 22.6 percent from a year earlier to $91.94 billion in April, the Customs said Tuesday. This was steeper than March's 17.1 percent decline. Imports slumped 23 percent in April, compared with a 25.1 percent decline in March.
"We expect fixed asset investment to be the single most important contributor to China's GDP growth in 2009," Jing Ulrich, chairwoman of China Equities at JPMorgan said in Beijing yesterday. Ulrich reckoned that investment could account for 45 percent of China's economy this year, if it maintains a growth rate between 25 percent and 30 percent for the rest of the year.
Analysts said the recent recovery of the housing market was likely to lend more support to investment growth. Real estate investment, accounting for more than one third of the nation's fixed asset investment, grew 4.9 percent in the first four months of the year, up from 4.1 percent for the first quarter.
Meanwhile, the pickup in housing prices may also help fuel investment in the sector. According to the National Development and Reform Commission, average housing prices in the 70 major cities edged up 0.4 percent in April from a month earlier, although it represented a 1.1 percent drop from a year earlier.
Investment represented 42 percent of China's GDP, compared with consumption's 48 percent and net exports' 9 percent. Analysts have long criticized the economy's excessive reliance on investment and exports, which make it particularly vulnerable to economic fluctuation abroad.
"In the short run, the rise of government-led investment is necessary to stabilize the economy," Ulrich said. "But the money should not be spent on building new manufacturing capacity, given the prevalent capacity in some industries."
Investment related to the government stimulus package is expected to help cushion the impact of the drastic decline in foreign demand.
The nation's foreign trade sector provided more than 80 million job opportunities, the Ministry of Commerce said in a statement yesterday. It said the nation's foreign trade sector is still facing serious challenges, despite the government's moves to boost the sector.
The World Trade Organization estimated that global trade is likely to drop 9 percent in 2009, the steepest decline since World War II.
China's leading trade fair, the Canton Fair, concluded last Thursday with export orders down 17 percent, which analysts said was a sign of further weakness of the sector.

CPI declines,
The specter of deflation is fading even though consumer and producer prices have continued to fall, economists said Monday.
The Consumer Price Index (CPI), a key gauge of inflation, fell 1.5 percent in April from a year earlier, the third straight month of decline.
The index declined at a quicker pace in April, the National Bureau of Statistics said Monday. The drop was 1.2 percent in March.
The Producer Price Index (PPI), which monitors factory-gate price changes, slid for the fifth month, dropping 6.6 percent in April from a year earlier, compared with 6 percent in March.
"Although the indices continued to see negative growth in April, deflationary concerns appear to be subsiding as the economy shows signs of recovery," said Jing Ulrich, chairman of China equities at JPMorgan.
Analysts said the fall of the indices is not as worrisome as it appears because of their high reference point - sharp rises in the prices of food and raw materials last year and their subsequent fall in the early months of this year.
For example, pork prices plummeted 28.6 percent in April from a year earlier. And crude dropped 53.6 percent, despite a recent rally on global markets.
"As the economy continues to recover and credit growth continues to expand, consumer prices should show an uptrend in the second half of the year," Ulrich said.
Over the past months, there have been signs that the economy has bottomed out. Strong loan growth and the government's $586-billion stimulus package are expected to prop up investment and help offset the impact of shrinking exports, which have long been a growth engine.
Banks extended 591.9 billion yuan ($86.3 billion) in new loans in April, up 27.1 percent from a year earlier. That put new lending for the first four months at 5.17 trillion yuan, more than the figure for the whole of last year.
M2, or the broader measure of money supply, surged 25.95 percent by the end of April, compared with 17.82 percent for 2008.
Analysts say the lion's share of the loans went to government-backed infrastructure projects in the stimulus plan. That would help revive demand and stabilize the prices of industrial products in the coming months.
Meanwhile, there are few signs of deflationary expectation among consumers, as sales in housing and car markets have rebounded.
Frank Gong, chief economist at JP Morgan, said in an earlier interview that deflationary expectation was a major threat for economic recovery, as it would mean consumers delay spending.
Auto sales rose 24.97 percent in April to 1.15 million units, hitting a fresh record and making the country the world's largest auto market for the fourth consecutive month, the China Association of Automobile Manufacturers reported last week.
Housing sales also rebounded. Industry specialists say sales volume in Beijing, Shanghai and Shenzhen grew more than 100 percent in the first quarter from a year ago.
Sun Mingchun, an economist with Nomura International, said the government's stimulus measures and strong loan growth would push up PPI and that, in turn, would lead to a higher CPI. He expects China's CPI to rise 2.3 percent in the fourth quarter year on year.

Unified European response to the wireless semiconductor industry competition
There are much larger than the mobile phone market of electronic products么? Do not think so. There are much bigger than the wireless semiconductor semiconductor applications it? I am afraid it is very difficult. In such a huge market space for the temptation, the competition is not only naked, but also bloody, and sometimes their own, only more powerful in order to resist the brutal competition in the market, but also to more brutal treatment of its own competitors. New Year, as there is a mobile phone chip giant to set up, cell phone chip industry restructuring is not only not over, it led to changes in a more lively, and this time the changes in the wireless semiconductor market may be the reorganization of the pattern of the real beginning of ... ... Old speech - farewell to the old giant All contact phone more than five years or more consumers, all have cell phones Philips impressed by ultra-long standby time, at least in that era just have a cell phone, philips phone is synonymous with ultra-long standby, while Philips is in addition to TI at the time outside the phone baseband chip's second largest supplier. Time flies, Philis, not only the sale of the original cell phone sector, and the sale of the entire semiconductor sector. Today, cell phone chip industry will bid farewell to Philips complete the trade marks, the future, Philips will work with mobile phone chip mobile phone industry or even the whole, perhaps we can only be part of mobile phones and other speakers to have been able to continue to search for Philips in the mobile phone industry some brilliant mark However, NXP logo is also eye-catching signs into the bottom right corner of the small "Founded By Philips". In fact, private equity funds from NXP was the beginning of the acquisition of Glass, Philip chips and cell phone contact only on the NXP name only the 20% stake, while the ST acquisition NXP wireless sector after 80% of the shares, Philips also nominally 4% stake in the new company, now transferred to the ST with the NXP remaining 20% ST-NXP Wireless stake in mobile phone industry can be formal and the former Philips chip and mobile phone giant to say goodbye, and the other, Philips! New Year - new giant aggressive Philips withdrawal is due to a sufficient change in the pattern of mobile phone chip market to buy there, August 21, STMicroelectronics (ST) announced a more than half a month just to run the ST-NXP Wireless and Ericsson Mobile Platforms will cause the Department (EMP , Ericsson Mobile Platforms) the merger of ST At the same time, NXP will acquire ST-NXP Wireless hands of the remaining 20% stake in ST and Ericsson finally in the new company 50 percent stake each. This move on the entire wireless semiconductor chip market in particular, the impact of mobile phones can be called unprecedented, even before the merger of ST-NXP Wireless also far-reaching. At the same time in the fierce market competition is the fastest-growing wireless semiconductor market, ST and NXP merge wireless sector in fact has changed the market structure, Figure 1 is the ST-NXP Wireless before the merger changes in semiconductor market share, ST-NXP Wireless has been opened with the gap behind competitors. This time, with the EMP sector to join Ericsson, the future of new semiconductor company will become more open and distance behind the competitors, and close to the front of the two market leaders. Many analysts also pledged six months ago that the two leading manufacturers of wireless semiconductor market pattern of mutations in six months after the situation, the real formation of the three wireless chip market trend.

New York City flyover
WASHINGTON -- President Barack Obama has ordered an internal review to determine how the decision was made to send of one of his official airplanes on a low-flying photo op past the New York City skyline.
White House press secretary Robert Gibbs said Tuesday that deputy chief of staff Jim Messina will lead the review. Gibbs said the point is to determine "why that decision was made and to ensure that it never happens again."
In this image taken with a cell phone by Jason McLane, the primary presidential aircraft, a Boeing 747 known as Air Force One when the president is aboard, flies low over New York Harbor, followed by an F-16 chase plane during a federal government photo op Monday, April 27, 2009. [Agencies]
Gibbs said Obama was "furious" when he heard about the incident. Obama has called it a mistake.
Related readings: On Monday, one of the Boeing 747s used by Obama and an F-16 jet circled the Statue of Liberty at the start of the work day, startling workers in lower Manhattan who feared a nightmarish replay of the 2001 terrorist attacks.
Gibbs said that the review would likely take about a week or so to complete. He said he would have to confer with White House lawyers before answering a question about whether the results would be made public.
The director of the White House military office, Louis Caldera, took the blame for the incident in a statement Monday

Officials say US deaths expected from swine flu
NEW YORK -- The global swine flu outbreak worsened Tuesday as hundreds of students at a New York school fell ill and federal officials said they expected to see US deaths from the virus.
Cuba suspended flights to and from Mexico, becoming the first country to impose a travel ban to the epicenter of the epidemic. The mayor of the capital cracked down further on public life, closing gyms and swimming pools and ordering restaurants to limit service to takeout.
A statue is seen on Reforma Avenue in Mexico City, on April 27, 2009. [Agencies]
Confirmed cases were reported for the first time as far away as New Zealand and Israel, joining the United States, Canada, Britain and Spain.
Swine flu is believed to have killed more than 150 people in Mexico, and the Centers for Disease Control and Prevention said the US has 68 confirmed cases in five states, with 45 in New York, one in Ohio, one in Indiana, two in Kansas, six in Texas and 13 in California.
Special coverage:Swine flu outbreak
Related readings: S Korea testing suspected swine flu case Pig farm might be source of swine flu: report Swine flu fears drive China's soybean futures sharply down Swine flu epidemic enters dangerous new phase"I fully expect we will see deaths from this infection," said Richard Besser, acting director of the CDC.
That was echoed by Homeland Security Secretary Janet Napolitano.
"It is very likely that we will see more serious presentations of illness and some deaths as we go through this flu cycle," she said.
President Barack Obama asked Congress for $1.5 billion in emergency funds to fight the illness.
In New York, there were growing signs that the virus was moving beyond St. Francis Preparatory school, where sick students started lining up last week at the nurse's office. The outbreak came just days after a group of students returned from spring break in Cancun.
At the 2,700-student school, the largest Roman Cathlic high school in the nation, "many hundreds of students were ill with symptoms that are most likely swine flu," said Health Commissioner Thomas Frieden. The cases haven't been confirmed.
Twelve teachers reported flu-like symptoms as well, said the principal, Brother Leonard Conway.
A nearby public school for special education students was shut down after more than 80 students called in sick. Frieden said that some of the students have siblings at St. Francis.
"It is here and it is spreading," Frieden said.
Still, US officials stressed there was no need for panic and noted that flu outbreaks are quite common every year. The CDC estimates that about 36,000 people in the United States died of flu-related causes each year, on average, in the 1990s.
The increase in cases was not surprising. For days, CDC officials said they expected to see more confirmed cases — and more severe illnesses. Health officials across the country stepped up efforts to look for symptoms, especially among people who had traveled to Mexico.

LED spots light up art gallery in China
LEDs have been used to change the way art is viewed in China.Z-Power LEDs from Seoul Semiconductor were used as spotlights for the exhibits at Da An Art Gallery in Zhongshan City, China.One benefit of LEDs is that they do not emit ultraviolet radiation, so do not required the filters used with traditional halogen and fluorescent lamps to protect the pictures.The installation replaced 50W halogen lamps with 7.2W LED spotlights, which according to Seoul Semiconductor could have a 85% power saving. The Z-Power LED P4 series used in the gallery spotlights has the colouring rending index of 93 indicating high level of natural expression of light colours, and high efficiency, which is optimal for lighting of museums and galleries.Da An Art Gallery located in Zhongshan City in Guangdong Province contains the works of Jun Tien Lee, a famous calligrapher and sculptor in that city.The gallery is replacing the halogen lamps and fluorescent lamps with LEDs in a eco-initiative.

Redesign Bravery And The Nature Of Feedback
When Facebook recently revamped its website, widening and dividing its pages into tabs, its staff probably foresaw the initial outcry. Redesign rage is pretty common, and most sites receive some negative feedback when they change things on a large scale. SEOmoz has received an uncommonly high number of positive comments every time we've redesigned, but we still have to filter the feedback and figure out what works and what doesn't.Our UI designer Timmy let me use the new Q&A section of the site for a few days before asking me, in a more specific fashion, if it worked all right. Q&A, in fact, has changed far less than some other parts of the site, although I appreciated both the question and the fact that he let me get used to it before asking for feedback. Because redesigns aren't just about what the site looks like: they're about how it functions.In the secondary navigation at the top of the screen (the blue bar), you'll see a drop-down menu labeled "SEO Resources." From that list, people can access PRO Guides, video tutorials and PRO tips, the Social Directory and Link Directory. Some of these things were notoriously difficult to find on our old site: I could never remember how to best access some of them and I always typed in the URL instead. How's that for usability?Changes such as this aren't done for the sake of aesthetics and suggest that one should not judge a redesigned website too quickly. It's really easy to lay eyes on something different and immediately decide that it's unpleasant. In fact, being unsure about something seems to be a basic human response to visual change.

Company Profile
STMicroelectronics is the world’s fifth largest semiconductor company with net revenues of US$9.84 billion in 2008.
The Company’s sales are well balanced among the semiconductor industry’s five major high-growth sectors (approximate percentage of ST’s sales in 2008 (1)): Communications (36%), Consumer (17%), Computer (16%), Automotive (15%) and Industrial (17%).
According to the latest industry data from iSuppli, ST holds market leadership in many fields. For example, the Company is the leading producer of application-specific analog chips and power conversion devices. It is the #1 supplier of semiconductors for the Industrial market, set-top box applications, and MEMS (micro-electromechanical systems) chips for portable and consumer devices, including game controllers and smart phones. ST also occupies leading positions in fields as varied as automotive integrated circuits (#3), chips for computer peripherals (#3), and the rapidly expanding market for MEMS overall (#5).
Product PortfolioST aims to be the leader in multimedia convergence and power applications, offering one of the world’s broadest product portfolios, including application-specific products containing a large proprietary IP (Intellectual Property) content and multi-segment products that range from discrete devices to high-performance microcontrollers, secure smart card chips and MEMS devices.
The Company provides solutions for a wide array of Digital Consumer applications, with a particular focus on set-top boxes, digital TVs and digital audio, including radio. In the Computer Peripherals arena, ST provides leading solutions in data storage, printing, visual display units, power management for PC motherboards, and power supplies. A wide range of ST’s ASSPs (Application Specific Standard Products) power sophisticated Automotive systems such as engine control, vehicle safety equipment, door modules, and in-car infotainment The Company also supplies industrial integrated circuits (IC) for factory automation systems, chips for lighting, battery chargers and power supplies, as well as chips for advanced Secure Access applications.
ST pioneered and continues to refine the use of platform-based design methodologies for complex ICs in demanding applications such as mobile multimedia, set-top boxes and computer peripherals. The balanced portfolio approach allows ST to address the needs of all microelectronics users, from global strategic customers for whom ST is the partner of choice, for major System-on-Chip (SoC) projects to local enterprises that need fully-supported general-purpose devices and solutions.
To maximize the benefit of scale that is becoming increasingly important in some semiconductor markets, ST completed the creation of two joint ventures in 2008. In the memory field, ST, Intel and Francisco Partners formed a new company, Numonyx, dedicated to providing non-volatile memory solutions, including NAND and NOR Flash memories as well as MCP (multi-chip package) memory solutions, for a wide variety of consumer and industrial applications. ST holds a 48% share in Numonyx.
ST has also been very active in the wireless arena. In mid 2008, ST and NXP combined their key wireless semiconductor operations in a joint venture, in which ST held 80%. In February 2009, ST acquired the minority stake from NXP and merged its wireless operations with Ericsson Mobile Platforms to create ST-Ericsson, a 50/50 joint venture focusing on semiconductors and platforms for mobile applications.
Research & Development and ManufacturingSince its creation, ST has maintained an unwavering commitment to R&D and is one of the industry’s most innovative companies. In 2008, ST spent US$2.15B in R&D, which was approximately 22% of the Company’s 2008 revenues. ST’s process technology portfolio includes advanced CMOS (Complementary Metal Oxide Semiconductor) logic including embedded memory variants, mixed-signal, analog and power processes. In advanced CMOS, ST is a partner in the IBM consortium for the development of next-generation process technologies, including 32nm and 22nm CMOS process development, design enablement and advanced research adapted to the manufacturing of 300mm silicon wafers. ST and IBM also cooperate at ST’s Crolles 300mm facility in the development of value-added CMOS derivative SoC technologies.
ST has a worldwide network of front-end (wafer fabrication) and back-end (assembly and test and packaging) plants. ST’s principal wafer fabs are presently located in Agrate Brianza and Catania (Italy), Crolles, Rousset and Tours (France), and Singapore. The wafer fabs are complemented by highly efficient assembly and test facilities located in China, Malaysia, Malta, Morocco and Singapore.
AlliancesFrom its birth, ST has established a worldwide network of strategic alliances, including product development with key customers, technology development with customers and other semiconductor manufacturers, and equipment- and CAD-development alliances with major suppliers. These industrial partnerships are complemented by a wide range of research programs conducted with leading universities and research institutes around the world, in addition to playing a key role in Europe’s advanced technology research programs such as CATRENE (Cluster for Application and Technology Research in Europe on NanoElectronics), a successor to MEDEA+, and industry initiatives such as ENIAC (European Nanoelectronics Initiative Advisory Council).

Since then ST has made outstanding progress; for example, energy and water consumption per product unit have been reduced by 5% and 9% per year, respectively, since 1994 and CO (2) emissions have been reduced by 61% over the same timescale. In 2006 and 2007, ST achieved absolute reductions in CO (2) emissions despite increased production volumes. Over the past 15 years, the Company’s sites have received more than 100 awards for excellence in all areas of Corporate Responsibility, from quality to corporate governance, social issues and environmental protection.
ST is a member of the key sustainability indices DJSI (Dow Jones Sustainability Index), FTSE4Good and ASPI (Advanced Sustainability Performance Index), and its corporate responsibility policy is detailed in its Principles for Sustainable Excellence (2), while its performance in terms of economic, social, environment, health & safety, product responsibility and supply chain issues is reported in detail in its annual Corporate Responsibility Report (3).
Facts and FiguresSTMicroelectronics was created in 1987 by the merger of SGS Microelettronica of Italy and Thomson Semiconducteurs of France. Since its formation, ST has grown faster than the semiconductor industry as a whole and it has been one of the world’s Top Five semiconductor suppliers since 2005.
The group totals over 50,000 employees, 16 advanced research and development units, 39 design and application centers, 15 main manufacturing sites and 78 sales offices in 36 countries.

7 Good Twitter Monetization Strategies
I've been getting into Twitter (under my usual moniker - randfish) more and more over time (despite only following a few friends and family), and lately, its been weighing on me that the service, despite its brilliance, rapid adoption and passionate fanbase, isn't yet pursuing revenue. That's OK - I think they probably have lots of very smart, talented, experience people thinking about the problem and taking action to prepare for it. However, I thought it might be fun to brainstorm some concepts publicly and recruit the smart SEO crowd to pitch in.
First off, here are the ideas I'd toss - I don't think they make good sense. Thumbs down to:
Third-Party Contextual Advertising - Google AdSense or YPN just don't excite me, and I think they'd undermonetize and be limited to only those folks who use Twitter on the web (and not through third party apps or mobile).
Broadcast Tweet Ads - Sending users a random ad tweet every 5, 10 or even 50 tweets isn't exciting and it's not targeted the way Twitter should be. Twitter knows something about everyone; leverage that if you're going to message your users.
Display Ads - For the same reasons as contextual advertising
Third Party Aps & APIs - I love that it's free now, and I think Twitter will be far more valuable by remaining completely free to users and open to developers.
Pay for Corporate Accounts - Can't prove you're a real person? Twitter charges for your corporate/brand account. It's an easy one (even if people set up lots of sock puppets to get around it, Twitter's sales/spam team can go find the valuable accounts), but it doesn't have the targeting value or the potential that some of the others do.
Pay for Followers - Twitter fans are going to get angry quickly if you auto-sign them up to follow a brand or person they don't know. I'd stay far away from this one.
Pay for Followed Links - Something tells me Google would be pretty quick to penalize Twitter and they probably don't want to make enemies with the search giant just yet. :-)
And here's some ideas I really like:
Keyword Purchases - Every time someone Tweets the word "SEOmoz," I, as an advertiser, want two things. First, I want those users recorded so I can message to them in the future and second, I want the word to automatically become a link pointing to the page of my choosing (probably a Twitter-specific landing page for PRO in our case).
Search Ads on Twitter Search - As Twitter search becomes more popular (and it will, not just for obsessed Twitterers, brand managers and reputation analysts, but for regular users and marketers and researchers, too), placing relevant ads in those searches becomes valuable. Better yet, you can combine Twitter searches with tweet history, so I could, for example, only show my ad to Twitter users who search for "SEO" and have previously twittered (or received twitters from those they follow) with my brand name.
Charging for Power Accounts - Your first 1,000 followers are free. After that, no one can follow you until you pay $50 a year (or some nominal, but affordable number). When you get to 5,000 or 10,000, the price goes up.
Subscribe Invitations from Advertisers - When I log into Twitter or reach my account page on the site, an overlay could indicate that some users have invited me to follow them. Those "invitations" could have 140 characters to say something clever and enticing enough to attract me and Twitter could target them based on my followers, followees and tweet history. There's a lot of targeting options for a brand manager seeking new followers.
Targeted Tweet Ads Based on Tweet History - Unlike the broadcast ad concept I didn't like above, these would rely on user history and profile to make them effective. If I've tweeted a combination of words a number of times or follow people who have, I'm an ideal candidate to receive a sponsored tweet every 20 or 50.
Opt-In Geo-Tweet Ads - You Tweet a location and advertisers can Tweet back (and appear in your mobile updates) with messaging. It's a pretty solid concept, although I worry that opt-in adoption rates would be low unless the advertiser quality controls were extremely high.
Pay to Opt Out of Ads - Don't want to receive Tweet ads or sponsored tweets (and maybe get some extra member features like a more robust timeline and maybe greater visibility or listing in some sort of Twitter user directory)? Pay $3 or $6 or $9 a month. It's a great extra revenue stream for those who'd (inevitably) complain about the ads.
Your turn - any good ideas for how Twitter should monetize? Any guesses as to which they'll adopt and when?
p.s. I recognize that many folks around the web have probably already voiced these ideas, and I've glanced at a few headlines on the topic, but thought I'd come at it independently without reading anything else first. If this were my job, I'd approach it much more systematically.

Buying Expired Domains: What's the Best Strategy?
Lately I've noticed a lot of questions in Q&A centering on purchasing expired domains. A lot of our members have expressed interest in buying old domains for a variety of prices (some are cheap, some are going for upwards of $50k) and want some advice on what to do with the domains once they've been purchased. I'm no domainer, nor am I an expert in such a business tactic, but I generally recommend one of three different options for an expired domain (and would love to hear more if you've got any). Option #1: 301 Redirect the Old Domain to Your Existing DomainThe easiest and least time consuming option is to 301 redirect the old domain to your existing site. This tactic obviously works best if both sites are in the same sector and are targeting the same keywords; otherwise, if you have a pet supply site and you buy an old Texas Hold 'Em poker site, a redirect probably might raise some eyebrows among the search engines. If, however, your site is brandnamepets.com and you buy onlinepetsupply.com and 301 redirect the domain over, you're inheriting a lot of topical and appropriate links. PROS:
Is the least time consuming option
Benefit from the value (about 95% or so) of the old domain's links CONS:
Old branded anchor text pointing to your new site isn't going to help as much as a keyword-rich anchor text
If the old site had a penalty (for shady link building, cloaking, spamming, etc.), the penalty could carry over to your new site (I can't confirm this to be true, but a lot of SEOs I've talked to believe that this is a possibility, and some have sworn that they've experienced it firsthand, so I guess you just have to be cautious) Option #2: Create a Microsite That Links to Your Existing DomainThe second option requires a bit more time and effort than a 301 redirect. You could do a mini overhaul of the site and turn it into a microsite for your main domain. This option is good for exact-match domains for your targeted keyword, and there are other reasons for going the microsite route that Rand's highlighted in his post about root domains, subdomains, subfolders and microsites. This strategy also works better if the old domain has decent rankings for the keywords you're targeting. PROS:
Can cross-promote/cross-link to your existing site
More real estate in the SERPs means more branding and potential conversions for your site
You can do stuff on your microsite you may not want to do with your main site (e.g., launch silly viral content, experiment with a promotional tactic)
You don't have to have a completely robust site; a lot of microsites are smaller and have a single focus (e.g., center on a quiz or a centric idea) CONS:
Can be time-consuming to do an overhaul of the old site
Aggressive promotion and linking to the existing domain can seem spammy and you could get penalized for reciprocal linking or setting up a link farm
Your current site isn't inheriting any of the old site's link value that would have come via a 301 redirect
Microdomains can be used ineffectively (see Rand's Whiteboard Friday about the microsite mistake) Option #3: Overhaul the Old Domain and Operate It IndependentlyThe third option is the one that's the most time consuming but also has its benefits. It's like having a successful restaurant and buying another restaurant and operating them simultaneously. They're not the exact same restaurant, but both are popular in their own right and make you money. The same goes for Option #3. You could update the content on the old domain and sell the same products that you're selling on your current site. If you can get both sites to rank alongside each other in the SERPs, you're increasing your conversion chances and sales potential. PROS:
As with Option #2, you get more real estate in the SERPs if you can get both sites to rank for your targeted search terms
You don't have to work hard to brand the old site if it's a generic, keyword-rich domain--you can just focus on getting rankings and conversions
The old site already has links pointing to it and is more established than starting with a brand new domain CONS:
You have to ensure that the old site doesn't mimic the new site and runs into any duplicate content issues
It's time consuming to revamp and maintain the old site (you've essentially doubled your workload)
As with Option #2, aggressive cross linking between the sites can raise red flags Your course of action really depends on how much work and effort you can put into the expired domain. If you're barely able to maintain and optimize your current site, you probably want to just 301 redirect the old site. If, however, you're more creative and have some time on your hands, you can try your hand at crafting a microsite. If you really know your stuff and are experienced at making money off various websites, you'd probably do well with the third option. Here's where I open things up: do any of you have experience buying old domains? If so, what do you do with them and has your decision worked well for you? Are there any other strategies you recommend?

Introduction to SDCC: Small Device C Compiler
SDCCis a Freeware, retargettable, optimizing ANSI - C compiler that targets the Intel 8051, Maxim 5962-0051101NXD , Zilog Z80 and the Motorola 68HC08 based MCUs. Work is in progress on supporting the Microchip PIC16 and PIC18 series. AVR and gbz80 ports are no longer maintained. The entire source code for the compiler is distributed under GPL.
Some of the features include:
ASXXXX and ASLINK, a Freeware, retargettable assembler and linker.
extensive MCU specific language extensions, allowing effective use of the underlying hardware.
a host of standard optimizations such as global sub expression elimination, loop optimizations (loop invariant, strength reduction of induction variables and loop reversing ), constant folding and propagation, copy propagation, dead code elimination and jump tables for 'switch' statements.
MCU specific optimisations, including a global register allocator.
adaptable MCU specific backend that should be well suited for other 8 bit MCUs
independent rule based peep hole optimizer.
a full range of data types: char (8 bits, 1 byte), short (16 bits, 2 bytes), int (16 bits, 2 bytes), long (32 bit, 4 bytes) and float (4 byte IEEE).
the ability to add inline assembler code anywhere in a function.
the ability to report on the complexity of a function to help decide what should be re-written in assembler.
a good selection of automated regression tests.
SDCC also comes with the source level debugger 5962-0051201QHA , using the current version of Daniel's s51 simulator. (Currently not available on Win32 platforms).
SDCC was written by Sandeep Dutta and released under a GPL license. Since its initial release there have been numerous bug fixes and improvements. As of December 1999, the code was moved to SourceForge where all the "users turned developers" can access the same source tree. SDCC is constantly being updated with all the users' and developers' input.

Photocouplers with Reinforced Insulation in the New SO6 Package: TLP109,TLP116A
The TLP109 and TLP116A are new additions to Toshiba's photocoupler family in small surface-mount packages. The new photocouplers are housed in the SO6 package, which is pin-compatible with the conventional MFSOP6 package. However, the maximum PCB mounted height has been reduced from 2.8 mm to 2.3 mm, making them ideal for low-profile applications. Additionally, for reinforced insulation, the TLP109 and TLP116A offer clearance and creepage distances of 5 mm or more and an internal Faraday shield with a thickness of 0.4 mm or more. SO6 meets the customer needs for both a thin package and a high level of safety standard compliance, bringing added value to your system.

STMicroelectronics Supervisory Board Resolves
Geneva, April 15, 2009 – The Supervisory Board of STMicroelectronics (NYSE:STM) today approved a proposal to submit to the forthcoming 2009 Annual General Meeting of Shareholders the distribution of a cash dividend of $0.12 per outstanding share of the Company’s common stock, payable in four quarterly installments from 2nd quarter 2009 through the 1st quarter 2010. The proposed dividend equals a 2% yield on the Company’s share price at closing yesterday on the NYSE.
The proposal will be submitted for shareholder approval at the Company’s Annual General Meeting, which will be held in Amsterdam on May 20, 2009.
The Company’s quarterly dividend of $0.03 per share, as proposed, compares to a quarterly dividend of $0.09 per share paid in the last twelve months.
“One of our key priorities for the Company in 2009 is to maintain a solid financial foundation and to further strengthen our Company for the long-term. As we navigate the current macro-economic environment, we have decided to maintain our dividend policy involving the distribution of a cash dividend, but are proposing, on a temporary basis, to reduce its level, reflecting today’s unstable market,” http://bg.data-sheet.org/datasheet_pdf/B/Z/BZW06-213B.html said.

The proposal will be submitted for shareholder approval at the Company’s Annual General Meeting, which will be held in Amsterdam on May 20, 2009.
The Company’s quarterly dividend of $0.03 per share, as proposed, compares to a quarterly dividend of $0.09 per share paid in the last twelve months.
“One of our key priorities for the Company in 2009 is to maintain a solid financial foundation and to further strengthen our Company for the long-term. As we navigate the current macro-economic environment, we have decided to maintain our dividend policy involving the distribution of a cash dividend, but are proposing, on a temporary basis, to reduce its level, reflecting today’s unstable market,” http://bg.data-sheet.org/datasheet_pdf/B/Z/BZW06-213B.html said.
