TIBA KE TAK TIBA

TIBA KE TAK TIBA

Engkau tiba...
Ke engkau tak tiba
Ke engkau nak tiba
Ke engkau tak jadi tiba
Ke engkau memang tiba
Ke engkau memang takkan tiba

Buat aku gundah gulana
Buat si rambut panjang mengiau
Buat si rambut panjang separuh hentak kepala ke meja
Buat si gelap terasa takkan putih
Buat si rendah terasa takkan tinggi
Buat si bapak lenguh liur

Kau tiba ke tak
Tiba kata tiba
Tak tiba jangan kata tiba
Tiba jangan kata tak tiba
Tiba ke tak tiba
Tak tiba ke tiba

Karang...
Tiba-tiba kau tak tiba
Tiba-tiba kau tiba
Tibalah tiba
Taklah tak

Tibalah
Lapang kepala semua!!!

Nukilan saat menantikan "buah yang tak gugur" untuk syarikat. 
Khabarnya minggu sudah, jadi minggu ni, pastu jadi minggu depan pulak.
Sudahnya jadi macam menunggu buah tak gugur.
-------------------------------------------------------------------------------------------------------------

EMBAH DAH PERGI

EMBAH DAH PERGI

Dia berwajah ceria
Seribu kedut wajahnya
Terukir kerana senyuman manisnya
Tawanya sekadarnya
Marahnya tanda wibawa

Tulang empat kerat
Dibanting penuh semangat
Pohon ditoreh sepenuh kudrat
Pelepah disabit basah dek keringat
Anak-anak takkan hampa meminta pastikan dapat
Cucu-cucu menumpang turut merasa rahmat

Kampung ke estet lanjut ke taman
Taman Seri Aman jadi hentian
Mengisi waktu penghakis zaman
Hanya isteri jadi teman
Bersama Wati pengisi kekosongan
Pengurus kehidupan

Gering tiba
Musibah menimpa
Derita tak terhambur dengan bahasa
Sengsara tak terukir dengan kata-kata
Tinggallah kulit dan tulang bernyawa
Tiada suara jauh sekali bicara

Mentari di barat
Dia dijelang sakarat
Anak cucu berderaian airmata
Suasana penuh hiba
Tinggallah sebuah kisah
Takkan bisa lagi digubah
Telah pergi insan disegani
Embah ... moga dirahmati
-------------------------------------------------------------------------------------------------------
Sajak untuk atuk. Beliau baru pergi menemui ilahi. Nukilan buat mengingati saat
pemergiannya. Moga dia sentiasa di dalam rahmat Allah yang Maha Esa.

UTAMAKAN HAK ALLAH

UTAMAKAN HAK ALLAH

Hak Allah bukan yang kedua
Untuk kita jaga
Allah akan sempurnakan dunia kita
Bila jadikanNya yang pertama
Asbab kita wujud di dunia
Yang lain jadi kedua ketiga dan ke seterusnya

Hak Allah paling utama
Berbanding semua perkara
Boleh buat kita bahagia
Boleh buat kita celaka
Boleh buat kita ke Syurga
Boleh buat kita ke Neraka
Selamanya

Sibuknya kita bekerja
Itu urusan dunia
Sibuknya kita berkarya
Itu urusan dunia
Sibuknya kita mengawal negara
Itu urusan dunia
Sibuknya menjaga rumahtangga tercinta
Itu urusan dunia

Semua jadi kedua ketiga dan ke seterusnya

Hak Allah yang pertama
Perhatikan ia
Jangan sekali terlupa
Jangan pernah jadikannya yang kedua

-----------------------------------------------------------------------------------------------------------
Sajak : Utamakan Hak Allah
Sebagai ingatan buat diri yang sering lalai untuk solat sebaik masuk waktu.
Padahal perkara melambatkan solat takkan berlaku kalau istiqamah menunaikan
solat di masjid secara berjemaah. Usia makin berkurang, tapi diri bagaikan di
takuk lama dalam ibadah. 
-----------------------------------------------------------------------------------------------------------

NAFAS PAGI

NAFAS PAGI

Pagi-pagi biar tenang
Bukan perang

Pagi-pagi biar senyum
Bukan mengaum

Pagi-pagi biar aman bahagia
Bukan huru-hara

Pagi-pagi biar harmoni
Bukan basi-basi

Pagi-pagi biar teratur
Bukan terabur

Pagi-pagi biar pahala tersalut
Bukan kusut serabut

Pagi-pagi biar macam nelayan turun ke laut
Bukan macam nelayan di pasar serabut

-------------------------------------------------------------------------------------------------------
Sajak : Nafas Pagi

Sajak pagi yang dinukilkan waktu pagi pada pagi yang serabut dan huru-hara.
Terhambur bahasa pagi yang diharapkan tapi entah bagaimana membentuknya.
Sesungguhnya pagi adalah permulaan hari baru selepas kita dimatikan seketika 
sebaik pertukaran hari menjelang maghrib. Sebaiknya ia perlu disambut dan dimulai 
dengan penuh kemanisan, keharmonian, pengharapan dan persediaan.

KACA SENJA

KACA SENJA

Semakin hari dia semakin tua
Semakin dimamah usia
Dulu tubuh bak besi waja
Tapi kini ibarat kaca
Saat untuk bersama
... tidak mungkin selamanya

Seusia wajanya
Kita dibentuknya
Kita dicanainya
Kita diberusnya
Kita digasaknya
Berserta untaian airmata
Kasihnya...
Manjanya...
Rindunya...
Sepayahnya...
Seadanya...

Kini dia berusia kaca
Andainya...
Terhentak retak selamanya
Terhempas berderai selamanya...
Takkan bercantum seperti sedia kala...
erlantar sakit
Kita...
Hasil acuannya...
Sehabis baikkah bakti kita kepadanya
Sehebat diakah kita menjaga kebajikannya
Sehebat diakah kita menakluki hatinya
Sehebat diakahkita berkorban harta dan masa untuknya
Sehebat diakah kita

Atau kita menjadi sang perobek hatinya
Atau menjadikannya pembantu rumah kita
Atau menjadikannya tetamu yang tidak diundang dan tidak disenangi
Atau kita manjadi penggali telaga air matanya...
Atau pencuri waktu ibadahnya pada usia senjanya...

Kitakah itu...

Sang senja pasti berlabuh jua
Saatnya sahaja kita takkan terjangka
Waktu tersisa
Kita jadilah anak yang paling berbakti kepadanya
Demi kebahagiaan kita dan dia di Sana..
Saat menghadapNya...

20:26/21 Mac/Mersing/Surau Sri Lalang
--------------------------------------------------------------------------------------------------------------------------
Aku tuliskan bait kata-kata ini saat mengenangkan ibu mertuaku yang terlantar sakit. Sajak ibu. Pada masa yang sama aku terkenangkan bagaimana sibuknya sang anak-anak dengan diari harian yang tersendiri. Meskipun beliau diziarahi, dilawati, dihantar untuk rawatan, namun aku terkenangkan bagaimana beliau menempuh hari-hari usia emasnya. Bagaimana perasaannya mengisi hari-hari tersisa tanpa suami tersayang yang telah lama pergi. Pengorbanannya dahulu adakah berbalas.

AWAS BICARA

Bila berbicara
Banyak caranya
Banyak kaedahnya
Banyak kesannya
Banyak faedahnya
Banyak bahananya
Banyak dosanya
Banyak pahalanya

Bicara mulut
Bicara mata
Bicara hati
Bicara akal
Bicara anggota

Kesemua bicara
Ada kesannya
Ada baik ada buruknya
Bergantung kepada
Apa penyampaiannya

Apapun wadah bicaranya
Ternilai pada isi bicara
Yang terisi pahala
Mahupun berisi dosa
Kesemuanya
Terakam kemas pada Sang Pencipta
Maha Mendengar segala
Maha mengetahui segala

Bicara penuh pahala
Indah sekali balasannya

Bicara penuh dosa
Perlu digeruni ancamannya

Yang mana bicara kita
Akal dan hati mencorakkannya
Nafsu gelora mencemarkannya

Bicara
Biar waspada

Bicara
Biar kenal batasnya
------------------------------------------------------------------------------------------------------------------
Sajak Awas Bicara aku nukilkan saat merasa sangat marah dengan viral Aisyah Tajuddin yang memperlekehkan hukum Allah iaitu Hudud. Beliau sama sekali tidak layak untuk melemparkan kata-kata seumpama itu atas apa jua alasan. Sama ada disuruh atau kerana makan gaji, pokoknya ia terkeluar dari mulutnya berserta kesungguhan bicara pada lenggok dan memek mukanya. 

Kesal dan marah pada tindakannya hanya mampu terluah pada sajak Awas Bicara. Buat masa ini itulah dulu luahan yang ada... banyak lagi... tapi pedas bahasa. Lain pula jadinya. Pada Aisyah Tajudin, ingatlah, kemaafan yang anda pinta tak selesaikan masalah yang ada. Bertaubatlah selagi masa berbaki. Kematian datang bila-bila. Bimbang tak cium bau Syurga. Pada yang marah, jangan memaki mencaci. Cacian itu juga ada balasan buat kita. Awas bicara...

InEco EV's steel-CFRP hybrid

InEco EV's steel-CFRP hybrid construction keeps weight under a ton 
The InEco demonstrator vehicle was displayed at the 2013 Frankfurt Motor Show
One of the quieter debuts at last month's Frankfurt Motor Show was also one of the more interesting. The InEco electric car, developed at the Dresden University of Technology's Institute of Lightweight Engineering and Polymer Technology (TU Dresden's ILK), combines an innovative mix of materials to keep its weight down to under a ton and allow it to get the most out of its small electric powertrain. 
A diagram of materials in the InEco car
InEco is an ongoing project by TU Dresden and several corporate partners, including Leichtbau-Zentrum Sachsen GmbH and ThyssenKrupp AG. At Frankfurt, the parties presented the first roadworthy demonstrator model, an urban-focused, four-seat hatchback. 
The InEco's consumption is 9.7 kWh / 100 km
The focus of the InEco project has been on experimenting with construction methods and material blends. The body and chassis of the car are built with a variety of materials, most notably steel and carbon fiber-reinforced polymer. 
The InEco is powered by a small 15-kWh lithium-ion battery and 120-hp electric motor
In using steel construction to augment and reinforce the CFRP, the InEco combines the advantages of both – the non-splintering malleability of steel, advantageous in crash protection, and the light weight, rigidity and high energy absorption of CFRP. Some structures are made strictly from steel, some from CFRP, some from a mix of both materials, and some from other materials like aluminum. The diagram below shows the different materials (in German) in use around the car's structure. 
A large grille and sharp headlamps define the InEco's front-end styling
According to TU Dresden, the steel-CFRP hybrid construction has allowed for the simplification of the car's design, cutting 70 percent of traditional bodywork components out. The research vehicle weighs just 1,984 lb (900 kg), including a 330-lb (150-kg) chassis, batteries and electric powertrain. That low weight allows a modest combination of 120-hp synchronous motor and 15 kWh lithium-ion battery pack to push the four-seat hatchback to 62 mph (100 km/h) in 7.5 seconds and on to a top speed close to 100 mph (160 km/h). The 100-cell battery pack keeps firing for around 75 miles (120 km) of driving distance. 
Inside the InEco
Those performance numbers don't sound all that different from current-generation electric vehicles, but the battery pack is smaller than average thanks to the car's low weight. For comparison, the Nissan Leaf uses a 24 kWh battery pack; the Ford Focus Electric uses a 23 kWh battery; and the Chevy Volt, a gas-electric hybrid, uses a 16.5 kWh battery. 
The InEco hood uses an ultralight sandwich construction
The InEco uses a central tunnel for its lithium-ion cells
Styling is often a distant afterthought when it comes to a technological research vehicle, but the InEco does manage to catch the eye with its Hyundai Veloster-like hot hatch look that comes courtesy of its sharp headlamps, descending roofline and wraparound-style glasshouse. While the InEco isn't likely to show up in dealerships anytime soon, some of the methods used in its construction may influence the automotive industry.

TECHNOLOGY : GPS UNTUK KESAN BASIKAL YANG DICURI

SpyBike GPS Tracker is like LoJack for bikes 

The National Bike Registry tells us that thousands of bikes are stolen every day in the United States alone, estimating a cost of around US$200 million per year. A stolen bike can take hundreds or thousands of dollars out of your pocket, leave you without a means of transit and turn into a frustrating, angering experience. 
The SpyBike flashes when it's armed
The SpyBike Covert Bicycle GPS Tracker protects you from theft by tracking down your bike. They may deserve every expletive-laced, demeaning name in the book, but there's no denying that bike thieves are crafty, determined folks. Even if you lock your bike up, thieves have a way of cutting, prying, hammering and hacking through your line of defense ... or maybe they'll just saw the fence post that the bike is secured to. Since you're not a professional thief, it's difficult to protect your bike from every possible scenario, and your bike could get stolen even if you make every attempt to lock it securely. The chances of you getting the bike back are slim, and you may not see it again even if the police recover it. 

The SpyBike GPS tracker from Integrated Trackers gives you a second line of defense. You should still lock your bike, but if a thief happens to break it free, you have a means to get it back. The device mounts inside the headset, where it is hidden and unassuming. You use a special wrench to secure the device, so it's not easily removed. Activate the unit when you leave your bike using the accompanying electronic key ring. If the bike is taken before being deactivated with your key (i.e. stolen), the vibration sensor initiates the tracking system, which sends you an alert SMS message and begins uploading coordinates to the cloud every 20 seconds until the vibration stops. 
You activate the SpyBike system with an electronic keyring
The unit will activate again when the vibration starts up (i.e. the thief is riding or transporting the bicycle), so you can continue keeping up on its whereabouts. You can keep track of the bike's location via Integrated Trackers' website, and then relay its location to the police. If you forgot to arm the unit before your bike was stolen, you can remotely activate it by sending an SMS message. It checks its messages automatically every six hours, so it will begin tracking when it gets your message. The tracking service is free, but users do have to equip the unit with a pay-as-you-go SIM card and will be charged for the data used in uploading coordinates. This may seem like an extra cost and work, but combined with the quad-band GSM modem, it allows the unit to work with nearly any mobile network in the world. You can configure it to the carrier that offers the best coverage in your area to ensure that it works when you need it. The unit uses GPRS to upload data, not SMS, and Integrated Trackers says it costs a fraction of a penny to send each update (in the U.K.). 
Secure the SpyBike unit with a special wrench
The SpyBike runs on a rechargeable lithium-ion battery. Integrated Trackers says that the battery can go for months between charges. The unit will send you an SMS message when the battery needs charging. The SpyBike does have some limitations. Because it relies on GPS, the device will stop operating effectively if your bike is taken inside or anywhere there isn't a clear view of the sky. In that case, the unit will step down to GSM cellular triangulation. 

The company says GSM is only accurate to about 650 feet (200 m), which could prove all but useless in a building-dense environment like the center of a city. In fact, even GPS's claimed 16 to 82 feet (5 to 25 m) accuracy won't necessarily bring you right to the thief's doorstep. Having a hidden tracking system keeping you updated on the bike's location will almost certainly increase your chances of recovery. 

By integrating it into the headset, Integrated Trackers makes it unassuming enough that thieves may not think to check for it, and difficult enough to remove that they won't be able to just pull it out or break it off. The remote activation feature is a smart inclusion that keeps the device active even if you don't have the key ring or your bike is forcibly stolen. 




The SpyBike starts at US$153.58. The following video shows you how it works in a theft scenario.

TECHNOLOGY : ALAT PENGESAN GPS SAIZ SYILING DENGAN KUASA SOLAR

COIN SIZED RETRIEVOR SOLAR-POWERED GPS TRACKING DEVICE
Retrievor is solar powered and roughly the size of a US quarter
 If you've ever wondered where you left the laptop or how your dog came home smelling like a frog pond, then a GPS tracking device might seem like a good idea. The trick is to find one small enough to be practical and doesn't need its batteries replaced every day. 
Size comparison of Retrievor's processor
The Retrievor RET-100 is a self-contained, solar-powered GPS tracker no wider than a US quarter that is looking to find a way to market via a crowdfunding campaign. According to its creators, the Retrievor tracker uses the smallest, fully integrated GPS module with on‐board antenna available. Measuring only 28 mm (1.1 in) wide with a thickness of 10 mm (0.3 in), it weighs only 12 g (0.4 oz) and tracks objects using a combination of GSM, GPRS, and GPS to provide redundancy and locate objects with an accuracy of to within 1.5 m (5 ft). 
Exploded view of the Retrievor

Design sketch of Retrievor
 Retrievor is powered by a SiRFstarIV GPS processor, which allows the unit to work in areas that are often difficult for GPS to reach, such as indoors, thanks to firmware that detects changes in temperature and satellite signals, and updates its internal parameters to aid near-continuous navigation availability. 

The unit is waterproof to a depth of 3 m (10 ft) and power for the Retrievor comes from an integrated solar panel and motion charger feeding a 3.7 V lithium-ion battery, which can also be charged via micro USB. 
Retrievor and its app
The  Retrievor works with free Android, iPhone and web apps that allow users to set “Geo-Zones” and have the device send a text, email or ringtone once it moves out of a predesignated area. The app also maps the Retrievor's location, including speed, distance traveled, and route taken, and can track several units at one time. 
Retrievor prototype

Retrievor with attachment clip
There’s also a multi-purpose attachment clip that hooks the tracker to things, such as pet collars. A $169 pledge to the indiegogo campaign that is running through November 14 is the minimum to reserve a Retrievor device. 
Retrievor Geo-Zone
Deliveries are expected to begin in January, provided the campaign reaches its goal. If the campaign is successful, the retail price will be set at $299. Use of Retrievor will require a US$1.79 monthly subscription fee charged annually in advance, with tracking of additional units to cost $1.59 a month. However, supporters of the indiegogo campaign will have their subscription fee waived for the first year.

TECHNOLOGY : SIMPAN CAS ELEKTRIK DALAM CIP SILIKON

SILICON SUPERCAPACITOR 

 Silicon supercapacitor could store electricity inside a silicon chip A team of researchers at the Vanderbilt University in Nashville, Tennessee has designed a supercapacitor made primarily of silicon that has shown much improved power density over its commercially available alternatives. The advance could allow for interesting integration of battery technology in everyday electronics, from solar cells to smartphones. 
A newly developed silicon supercapacitor could allow for the seamless integration of energ...

Supercapacitors store electricity by gathering ions on the surface of two plates soaked in an electrolyte solution. Because the number of ions that can be stored depends on the surface area of the plates, these are usually coated with materials, such as activated carbon, that are highly porous at the nanometric scale. 

While supercapacitors can't quite match the energy storage capabilities of lithium-ion batteries, they can absorb and release charge much more rapidly and have a significantly longer lifespan. Today, supercapacitors are used in applications ranging from stabilizing the power supply in portable electronics to supporting the KERS system in Formula 1 cars.

Scientists have tried to improve on the amount of energy that supercapacitors can store by depositing even more porous materials materials such as carbon nanotubes on their plates, but these attempts have only produced marginal improvements that have been hard to replicate consistently. 

Assistant professor Cary Pint and his colleagues at Vanderbilt chose to attack the problem from a new and unusual angle by attempting to build a capacitor out of porous silicon. At first this seemed like an unlikely path, since silicon is known to react strongly with the electrolyte, disrupting the working mechanism of supercapacitors.

The silicon supercapacitor showed higher energy densities than commercial devices, though ...

On the other hand, the electronics industry is very familiar with ways to manipulate silicon precisely and make it highly porous. Pint and his colleagues coated the porous silicon in carbon and heated the ensemble to about 800° C (1500° F). The process formed a layer of graphene only a few nanometers thick that insulated the silicon from the electrolyte while retaining its highly porous structure. 
On the left, the electrolyte used in the supercapacitor; in the middle, the furnace that w...

The researchers found that supercapacitor plates manufactured in this fashion were up to 40 times more energy-dense than those made out of the "naked" silicon, and achieved a performance that significantly improved on current commercial supercapacitors.
