Tovuti za Serikali [tanzania.go.tz/zanzibar.go.tz] zaongoza njia tovuti mbovu Tanzania

Tovuti ya Tanzania (tanzania.go.tz) ni katika miongoni mwa tovuti zilizokosa mvuto Tanzania. Tovuti imekosa uiano wa rangi katika kurasa zake. Vile vile imejaa viunganishi ambavyo havifanyi kazi, kama hii ambayo imeekwa kwenye kitufe cha 'back' http://www.tanzania.go.tz/index2.html ni kwasababu inajaribu kwenda kwenye amabyo imebadilishwa jina nakuwa 'index2E.html'.

Tovuti ya Zanzibar ni moja ya tovuti ambazo zipo katika hatari ya kuangushwa wakati wowote. Tovuti inakurasa za PHP ambazo zimejaa hitilafu za PHP (php bugs). Kurasa hizo zinaweza tendwa kirahisi, kwasababu zinaonyesha majina ya mafile. Kwa kifupi unaweza kuhack kirahisi.

Na mtu akipata hivyo kinachofata ni kuwa hacked. Kama ifuatavyo:

Ni ombi letu [tungule.com], tovuti ya serikali ya Zanzibar ifungwe iliirikebishwe kabla haijavamiwa. Na ile ya Tanzania, irekebishwe ili iwe na manufaa na iwe ya kutumika.

Samsung 5 series wa kwanza Chrome OS [Chromebook]

Samsung 5 series ndio wa kwanza kuzalisha 'Chromebooks'. Ni Laptops (bado tunatafuta tafsir yake,btty), ambazo zinatumia cloud-based Operating system. Laptops hizo zitakuwa zinatumia sekunde chache kuboot, na kuzimika mara moja. Software zote zitakuwa zinapatikana katika tavuti (web), tatizo la kuinstall software na kuifanya kompyuta kuwa slow linaondoka

Hata hivyo Chrome OS inahitaji upatikanji wa uhakika wa intaneti. Kwa Tanzania kwa watu wengi internet ni maofisini na wachache inapatikana nyumbani. Vilevile, inahitaji internet ambayo ni inspidi ya kutosha. Jee Watanzania wangapi watakuwa tiyari kuacha kutimia OS za kawaida na kutumia Chrome. Jee ukienda kwenye ambayo internet haipatikani kabisa?

From our Authors: Cloud Computing in Tanzania Healthcare

Information sharing in healthcare systems is one among the major issues which needs to be given a reasonable attention. To overcome the problem in many medical institutions opted for e-healthcare system. E-healthcare is becoming one among the vital topics in healthcare organizations (Dwivedi et al. 2002). Healthcare information systems face difficulties in implementing and maintaining these computing systems. This section of the proposal will review literature which addresses the whole information sharing in health system topic. First, this section will discuss on the problems facing the institutions information sharing and major drawbacks of using the current system. Second, the solution to be proposed that is cloud computing will be discussed; defining cloud computing and discussing the benefits cloud computing provides. Third, the literature will examine how cloud computing would fit healthcare system, specifically in Tanzania. Lastly, challenges and problems which are potentially to be faced will be highlighted.

Due to huge amount of data, hospitals face a lot of problems in sharing and storing data (Omary et al. 2009; Xinlei and Wang 2010). The amount of data to be processed and shared is so large and has made the whole process of storage a very laborious work. In Tanzania data is taken manually and stored using the traditional hard paper files. This is very expensive and time consuming work (Omary et al. 2009). According to Omary et al. (2009) the major problems using the traditional system it leads to data duplication, incomplete and irrelevant information. To overcome the problem Omary et al. (2009) suggest e-healthcare should be implemented in Tanzania. But then there rise another issue of installation and maintenance of the systems. Installation process involves cabling and purchase and installation of necessary hardware and software. In fact, the medical institutions have to invest money and manpower to implement e-healthcare (Rolim et al., 2010). Martinez et al. (2005) claim that the distance between the rural areas and the urban is huge in developing countries which make data sharing more difficult. There arises a problem “to see a doctor is difficult, to see a doctor is expensive”. Developing countries like Tanzania needs cloud computing to overcome the distance, have cost-effective healthcare and to have a proper data management system.

The proposed solution of the problems mentioned above is cloud computing. By definition cloud computing is the means though which computer infrastructure and capabilities are provided regardless of time and location (Wang and Tan, 2010). According to Wang and Tan (2010) all products provided by the cloud is viewed as a service. From the definition, cloud computing provides processing, distribution and storage services. Therefore Hospitals and medical institutions will not be forced in acquiring unnecessary hardware and software (Wang and Tan, 2010). Wei and Blake (2010) add that the institutions would pay for what they use, that is in the mode of “pay as you go”. The benefits of implementing cloud computing is that maintenance is easy, user only has to connect PC to the internet (Rolim et al., 2010). From the above we learn that cloud computing offers a very ideal solution for computing in Tanzania; it overcomes cost, availability and technical issues. The question to be asked, how cloud computing can solve the problem “seeing a doctor is difficult, seeing a doctor is expensive” in Tanzania healthcare system?

Bonacina et al. (2007) propose a system which uses a web-based platform which keeps medical information of a family. The proposed system may resemble cloud computing but it is not pure implementation because first the system is not connected to medical center system. That is it is a standalone application. Hence the system architecture does not comply with the definition of accessing the capabilities and infrastructure of computers whenever and wherever. Another system (Diag. 1) which uses censors to monitor patients’ heart rate and upload the data to the hospital cloud by Rolim et al. (2010). But then the acquiring of censors would cost more money and the aim is to minimize cost as possible. However, seemingly if we minus the censor part of the system and make little adjustments, the later proposed system looks the suitable cloud computing system to be implemented in Tanzania.

The above system is one among possible implementations of cloud computing systems in healthcare systems. The Rolim et al. (2010) proposed system will overcome the distance issue and facilitate telemedicine. Telemedicine is defined by Rolim and colleagues as providing treatment remotely. Thus medical clinics situated in rural can access and distribute medical information to regional and national hospitals. According to them this will help small rural hospitals to manage drug supply, financial management and even provide collaborative medical care. Furthermore, in general taking from the system, cloud computing will help mobilize healthcare (Bonacina et al., 2007). Wan and Tan (2010) add that cloud computing provides cost effective healthcare and provides a suitable base for medical information sharing. Therefore from the literature reviewed, it seems like cloud is prime candidate as a computing method to implement in Tanzania healthcare. It overcomes cost, distance, technical know-how and moreover it facilitates collaborative medicine.

On the other there are some challenges and security risk concerning implementation of computing. Omary et al. (2009) are concerned with lack unique identifier, lack of funds and internet availability. Currently, Tanzania is connected to optic fiber cable passing from South Africa to India and then connecting to Europe. Therefore, in Tanzania internet and bandwidth is no longer an issue. In addition to that there are other concerns like resistance to attacks and protection from SQL-injections (Wei and Blake 2010). These issues can be overcome with encryption and proper programming. The biggest challenge seems to be the popularization of cloud computing in Tanzania. Seemingly, cloud computing is a very new concept in Tanzania.

In conclusion, from literature review cloud computing would be a very suitable implementation in e-healthcare of Tanzania. Tanzania as developing needs a very cost-effective system and less laborious to reduce cost on staff. The literature has highlighted on challenges and risk which some of them are already eradicated or could be solved with available methods. Cloud computing is a new topic in Tanzania, but from the literature reviewed it is a topic which worth a study. No errors allowed in medical information and cloud computing is tool to ensure that.

Uwezekano:Nishati mbadala

‘Gongo’ ni aina ya pombe ambayo imepigwa marufuku nchini Tanzania. Kwa hakika, kuna madhara mengi yaliowahi tokea ambayo yamesababishwa na pombe hio. Kiutaalam, ‘gongo’ ni ‘Ethanol’. Ethanol imethibitisha kuwa ni nishati mbadala ambayo ni fanisi hasa kwa vyombo vya barabarani. Baadhi ya nchi zimekuwa zikitumia ‘ethanol’ hasa kwa usafiri wa umma. Sio tu ni nishati fanisi, bali pia inasifika kwa kutunza mazingira na kuwa madhara kidogo kwa hewa (“low carbon emmissions”).

Kutokana na maelezo hapo juu na kutokana na gharama za juu za usafiri nchini (angalia SUMATRA), ni wazi kwamba huu ni wakati wa kushirikiana na wapika gongo ili iwe inatumika kwa njia zinazofaa na kunafaisha. Wakina mama wanaopika gongo wakiwekewa ‘standards’ za kufuata na wakipewa ruzuku za kuwaezesha kufanya kazi, itasaidia kuzalishwa ‘ethanol’ nyingi. Ethanol ikipatikana nyingi na ya kutosha, nadhani ni wazi kwamba ni wakati wa kubadilika na kuanza ‘ethanol’ kwenye madaladala na mabasi ya miji badala ya kutumia petroli ambayo ni ghali na ambayo inamwaga uchafu mwingi kwenye hewa.

Faida ni nyingi, sio tu kutunza mazingira bali tutakuwa mfano kwa mataifa mengine ya Afrika. Bei za usafiri wa mijini itashuka kupelekea kupungua kwa gharama ya maisha mijini. Pia, akina mama ambão walikuwa wakiwindwa na vyombo vya sheria kwakutengeza pombe hii haramu, watakuwa wameweza jipatia ajira ambayo itakuwa msaada tosha kwa wao na kwa nchi kwa ujumla.

Hata hivyo, kuacha kutumia petroli na kuanza kutumia ‘ethanol’ ni vigumu mno. Kwanza, wazo hili litarajie kupata kipangimizi kikubwa kutoka kwa wamiliki wa masheli amabao upunguzi wa bei za mafuta ni kikwazo kwa wao si kwambii mada husika. Vilevile kisiasa ni maamuzi magumu kufanya katika nchi kutokana na athari kwa baadhi ya wafanya biashara wakubwa nchini.

Kwa kumalizia, faida za ‘ethanol’ ni nyingi, na kwa kuzingatia hali ya sasa, ni wakati wa kuanza kufanya utafiti ili tujikomboe kama nchi. Japokuwa kutakuwa na vipangamizi katika kuezesha uhamiaji huo, lakini faida zake ni muhimu sana. Ikiwa kweli tunataka kuwapunguzi wananchi ugumu wa maisha, basi jee hatuoni kwamba tunahitaji kuangalia nishati hii mbadala?

Cloud Computing Examined

Nice movie for office 2010 users!

I like this! It is all about commitment

Below are some benefits of Information Communication Technology revolution. It is a vision we should embrace too!

Teknolojia mpya ni ngumu bila umeme!

Tatizo la umeme ni kikwazo kwa watanzania hasa wanaotaka kubadilisha hali ya Teknolojia nchini. Nashindwa kuelewa, ni asilimia ngapi ya watanzania wanaishi bila ya umeme. Kilicho tokea Zanzibar ni aibu na tena jambo la kukatisha tamaa; mara mbili ndani ya miaka miwili. Au labda tujiulize kwa wale wanaopata umeme ni asilimia ngapi ya muda wa maisha yao wanakosa umeme? Uzalishaji wa umeme wa kutosha Tanzania ni muhimu kwa watu wake na kwa Taifa kwa ujumla.

Kwa kuongezea, ni kama uaji wa wafanya biashara ndogo ndogo. Sasa ndio wakati wa kulivalia njuga swala la umeme ili kukuza teknolojia na kukuza uekezaji. Wangapi wamekatisshwa tamaa kuwasilisha mawazo yao kisa sababu ya upatikanaji mdogo wa umeme. Pia, kazi ngapi zimeharibika baada ukatikaji wa ghafla wa umeme? Cha kushangaza nchi yetu inasifika kwa kuwa ya kijani, na huku hali ya nchi inalazimisha utumiaji wa majenereta yaanaochafua mazingira! Binafsi, sijwahi sikia nchi inaendelea kwa mgao wa umeme!

Kwa kumalizia, ni wazi kwamba uzalishaji wa umeme ni ishara tosha inayoashiria jinsi gani nchi ipo makini katika kuhakikisha swala zima la maendeleo. Maendeleo bila umeme unaokidhi mahitaji na unaopatikana saa zote ni ngumu. Wanasiasa wanajukumu, na jukumu lao kuhakisha wanasayansi wanaisaidia nchi yao na huu ndio wakati. Tunahitaji uzalishaji wa umeme na mgao sasa iwe basi.

How can you adapt to changes?

Thinking of changes and how tricky they could be sometimes, personally, I admire how the famous Bi Kidude copes with the changes and how prepared she was for the future. She has been singing ever since, and still, till today you would single her out as one of the best. I have a fair knowledge about her history, but seeing her now, using a newly upgraded microphone is amazing, isn't it?

Now, how well can we all adapt with changes, I am not sure, put me, you to the test. Hence, it is something we should consider in what we do for living. How many employees have been laid off by their companies just because they could not handle the technological changes? Personally, I think, this Madam below, is a good lesson to learn from.
