The future of K series from SonyEricsson?

As you may know, the SonyEricsson company bought software from the french mobile producer Sagem, during 2007.
Read here and here about this.

Although SE had claimed that Sagem products are mature, scalable and flexible, I dare to say NOT!.
As a requirement of my daily job, I had to work on several hundreds of mobile mobile phones devices, and I must confess that Sagem are far from easy to use handsets, regarding normal operations beyond the call/answer tasks (connecting to another provider, web surfing, launching web from java applications, etc).

This said, I wonder if SE company (by the way, I am a really big fan of their mobile phones) made a correct decision to buy Sagem software.

Now I am reading on GSMarena that SE is planning to replace the K series of their phones with the C one. No, not C from the end of the name as "...300c" from China, the "C" stands for CyberShot.

The "G" is "Generation Web" and the "S" will be the "Snapshot" (the old "S" was "Slide/Swivel").

What will be the future of the K series? I hope the new products will have even more success than their predecessors.


>>from GSM Arena

After a week of hard Sony Ericsson previewing here at GSMArena, seems like they are still making the headlines again this week. This time it's all about names. The Unofficial Sony Ericsson Blog revealed the new nomenclature scheme that Sony Ericsson will be using in their latest and future products.

Another reported change is that the "i"-symbol will be dropped from now on. As you can see here in the full Sony Ericsson portfolio there are already 8 handsets without the "i" tag. As it seems, all handsets that come without the tag will be following the new naming nomenclature as depicted on the right.

In the same time the "a" and "c" designations are here to stay - they would still denote model versions for the American and Chinese market.

The fate of the K-series is still unknown. Sony Ericsson fans have grown to love the K-phones over the years and we doubt that they will be dumping it so easily, but who knows.

As you already probably know, the new camera-centric mobiles by the brand will be named as C-series - that stems either from Camera or from Cyber-shot. The G-series, which we previewed last week, is named after the Generation Web platform.

And finally, the last reported change is that from now on, the S-series will mean "Snapshot" instead of "Slider/Swivel". We will see about that, as no new products have been announced with the "S" designation.

The rest of the series we've come to know will be left untouched. And you can bet we are looking forward to the Sony Ericsson P5 announcement this summer.

HDR pictures

First of all, I am not a photographer, nor related to the professional photography, nor even having a digital camera.


I've seen lots of photos in my life. Surfing the web, I even discovered several techniques to improve the visual impact of a photo. Visual impact doesn't mean only to boost the contrast of picture's color, but to send a much "visible" message to the viewer.


Since I am not professionally related to the image processing and not even owning a digital camera, I am more than a stranger to the daily tasks that an amateur to a professionally photographer is currently performing when is processing images.


But sometimes, I was questioning myself if it is possible to get from a picture more than we currently see in it. Some of the photos I've seen were good (as far as I can tell as a common viewer) and most of them were bad: not having the proper exposure, lot of blurring due to the lack of a tripod or anything to keep the camera still, vignetting, noise and other image flaws.


Sometimes I was picturing biggrin in my mind that someone could have better results if he will use the same picture, but taken in different conditions: under or overexposed, in order to get the picture to the same visual level as a human eye can do it.


Of course this is not possible with the current cameras in one shot only, but we can make the picture in 3 different exposures: under, normal and overexposed. Then, from each of these, we will extract the details we need.


Today I've found that there is such a technique, and is used to make HDR pictures (highdynamicrange).


Look at these photos:







There is nothing to not like them.


And those picture were made with the same technique I've just dreamed of: taking the same picture with 3 different exposures, and then combining into a image processing software as Photoshop or Photomatix.


More of these picture here: http://flickr.com/groups/bestofhdrpictures/pool/


You can search the net for HDR making techniques, as there are available few good tutorials.

Blogger how to - insert a script in blog - method 3

This post is the 3rd method to insert a script in your blog, as the first two methods were described here - 1 and here - 2.

As stated before - Warning: inserting anything, or modifying the xml template may destroy your blog, so be careful.
Backup your xml template every time you're modifying it, by clicking the "Download Full Template" link in the Layout -> Edit Html page of the blog admin area.

The 3rd method to insert a script in your blog is to insert the script code into a HTML page, as a blog widget.
In this manner, the xml template will not be put in danger.

To do so, go to the Layout section of the blog, then to "Page Elements".
In here, choose the positon of the widget (after or before the header, footer, into the sidebar, wherever) and select the "Add a page element" link.
Choose the "HTML/Javascript" widget and press "Add to blog".

In the next popup or windows which will be opened, insert the script code into the text area, between <script type="text/javascript"> and </script> tags.
In order to make this script invisible for the visitors (invisible means that the HTML widget will not be seen by the visitors, but it will be available in the blog and its code will run without problems), DON'T GIVE A TITLE TO THIS WIDGET.

The Blogger xml code in its default state will not display anything in the page which may reveal your script tricks if the html page doesn't have a title.
The script will be available in the page, although.

As an example, click onto the following picture and you may see a beautiful enlarge/fade effect.

Blogger how to - insert a script in blog - method 2

Ok, so in the first part, we have inserted a script into our blogger xml template by hosting that script on some external domain and then linking it in the template.
Now we will learn something about the source code of the xml template.

The second method to insert a script is by inserting the code itself into the xml source.
This is not an easy part, since the Blogger parser will scan the xml template.
The XML source code is a little different than a script code, that's why the Blogger parser will strip away a good piece of your script, making it useless and many times, screwing up the blog xml template itself.

So, for this method, you must be very carefull not to erase something important from the template, or even to lose the xml code.

First, before editing the xml code, backup your existing template. (click the "Download full template" link from the Layout-Edit HTML page)
This must be the first step you make every time you are editing something inside the source code.

To have much less chances to destroy your blog, keep in mind that this method must be used only for short, clear and not so aggressive scripts (without complicated mathematical and comparing operations).

All this said, the manner in which you will insert the script code is the following:
insert the script between <script type="text/javascript"> and </script> tags from inside the <head> </head> section of the xml layout.

Example:
<head>
...
<script type="text/javascript">
...your script here...
</script>
...
</head>

As an example on what's good a script for, click onto the following picture and you may see a beautiful enlarge/fade effect.

Blogger how to - insert a script in blog - method 1

Ever wanted to install a script in your blog, to do what ever you want to do? Maybe to apply a cool effect on some pictures, with fading and sizing animations, or maybe to count your blog visitors?

The Blogger xml template is a little difficult to handle in order to have a satisfactory result, without compromising the template integrity.
Well, if you want to do it, you have 3 options, each of them being suited for different approaches.

1. insert your script in the blogger xml template as a link to another hosting domain;
2. insert your script in the blogger xml template, as source code;
3. insert your script in another html widget, as source code.

Warning: inserting anything, or modifying the xml template may destroy your blog, so be careful.
Backup your xml template every time you modify it, by clicking the "Download Full Template" link in the Layout -> Edit html page of the blog admin area.

Let's take them one by one:
1. inserting the script in your xml template by linking it to another site.

You have a script and you want to run this script in your blog.
By default, the Blogger engine of the blog will scan your xml template and removes any block codes which are not suitable for the XML format. As you may (not) know, the xml architecture is a little different than the script one, so writing code pieces in the unsuitable format may ruin all your work.

You can save the script as .js file and host it at some place on the web.
So, in your xml template of the Blogger, insert the following line somewhere in the head section (between <head> and </head> tags):
<script src="path_to_your_script_file" type="text/javascript"></script>

Example: <script src="http://mydomain.com/myscriptfile.js" type="text/javascript"></script>

That's it.
The disadvantage of this method is that every time the external hosting domain is not available (maybe the server on which is hosted is not running), the script will not run also into your blog, so those cool effects that you wanted for your visitors are not available at all.

A second method of the tutorial will be available soon.

As an example on what to do with a script, click onto the following picture and you may see a beautiful enlarge/fade effect.

Blogger how to - moving author and timestamp to the top

This modification moves the authorname and the timestamp to the top of the post, just before the post title.

Edit the template in HTML-mode, and expand all widget templates. Search for the following line of code:

<b:includable id='post' var='post'>
Scroll down some more and find the following piece of code:
<span class='post-author'>
<b:if cond='data:top.showAuthor'>
<data:top.authorLabel/> <data:post.author/>
</b:if>
</span>
<span class='post-timestamp'>
<b:if cond='data:top.showTimestamp'>
<data:top.timestampLabel/>
<b:if cond='data:post.url'>
<a class='timestamp-link' expr:href='data:post.url' title='permanent link'>
<data:post.timestamp/> </a>
</b:if>
</b:if>
</span>
Or something like that. Just be carefull to copy all the content between
<span class='post-author'>
and its closing tag
</span>

Cut this code from the template.
Scroll back to the
<b:includable id='post' var='post'> 
and paste the code just after this line.

Note: check that there is a space between the closing </span>-tag and the opening <span>-tag, to separate the author name from the timstamp label.

Save the template.

Blogger how to - optimising h1 for a better SEO

Found on http://www.jackbook.com/blog-tips/optimizing-the-use-of-h1-for-a-better-seo.

Used Mimima default blogger template created by Douglass Bowman for the example here.

1. Go to your template editor. Then Tick the Expand Widget Template.

2. Find this code below,

<h1 class='title' style='background: transparent; border-width: 0px'>
<b:if cond='data:blog.url == data:blog.homepageUrl'>
<data:title/>
<b:else/>
<a expr:href='data:blog.homepageUrl'><data:title/></a>
</b:if>
</h1>
Change it to be like this below,
<b:if cond='data:blog.pageType != "item"'><h1 class='title' style='background: transparent; border-width: 0px'>
<b:if cond='data:blog.url == data:blog.homepageUrl'>
<data:title/>
<b:else/>
<a expr:href='data:blog.homepageUrl'><data:title/></a>
</b:if>
</h1>
<b:else/>
<h2 class='title' style='background: transparent; border-width: 0px'>
<b:if cond='data:blog.url == data:blog.homepageUrl'>
<data:title/>
<b:else/>
<a expr:href='data:blog.homepageUrl'><data:title/></a>
</b:if>
</h2>
</b:if>
Find this code below,
<h1 class='title'><b:if cond='data:blog.url == data:blog.homepageUrl'>
<data:title/>
<b:else/>
<a expr:href='data:blog.homepageUrl'><data:title/></a>
</b:if>
</h1>
Change it to be like this below,
<b:if cond='data:blog.pageType != "item"'><h1 class='title'>
<b:if cond='data:blog.url == data:blog.homepageUrl'>
<data:title/>
<b:else/>
<a expr:href='data:blog.homepageUrl'><data:title/></a>
</b:if>
</h1>
<b:else/>
<h2 class='title'>
<b:if cond='data:blog.url == data:blog.homepageUrl'>
<data:title/>
<b:else/>
<a expr:href='data:blog.homepageUrl'><data:title/></a>
</b:if>
</h2>
</b:if>
3. Done with the blog title.

Now we are going to set the H1 to the post title.

4. Go find this code below,
<b:if cond='data:blog.pageType != "item"'><b:if cond='data:post.title'>
<h3 class='post-title entry-title'>
<b:if cond='data:post.link'>
<a expr:href='data:post.link'><data:post.title/></a>
<b:else/>
<b:if cond='data:post.url'>
<a expr:href='data:post.url'><data:post.title/></a>
<b:else/>
<data:post.title/>
</b:if>
</b:if>
</h3>
</b:if>
</b:if>
Replace that code with this code below,
<b:if cond='data:post.title'><b:if cond='data:blog.pageType != "item"'>
<h1 class='post-title entry-title'>
<b:if cond='data:post.link'>
<a expr:href='data:post.link'><data:post.title/></a>
<b:else/>
<b:if cond='data:post.url'>
<a expr:href='data:post.url'><data:post.title/></a>
<b:else/>
<data:post.title/>
</b:if>
</b:if>
</h1>
<b:else/>
<h3 class='post-title entry-title'>
<b:if cond='data:post.link'>
<a expr:href='data:post.link'><data:post.title/></a>
<b:else/>
<b:if cond='data:post.url'>
<a expr:href='data:post.url'><data:post.title/></a>
<b:else/>
<data:post.title/>
</b:if>
</b:if>
</h3>
</b:if>
</b:if>
5. Done with the post title.

Now we need to adjust the style so your layout will keep the same as before.

6. Find this code below,

tips: if you use firefox, you can just press CTRL+F and then type this on the searchbox on the bottom left. “#header h1″

#header h1 {margin:5px 5px 0;
padding:15px 20px .25em;
line-height:1.2em;
text-transform:uppercase;
letter-spacing:.2em;
font: $pagetitlefont;
}
This is the style of your blogtitle. It says #header h1 isn’t?

Replace the codes with below,

#header .title {margin:5px 5px 0;
padding:15px 20px .25em;
line-height:1.2em;
text-transform:uppercase;
letter-spacing:.2em;
font: $pagetitlefont;
}
We just changed the style of our blog header. instead we set the style of h1 inside the id header, we set it to style “title” inside of id header.
If you are not familiar with StyleSheet (CSS) or HTML code, then just follow all the steps, and you will make it.

Now we need to set the post title style.
7. Find this code below,
tips: if you use firefox, you can just press CTRL+F and then type this on the searchbox on the bottom left. “.post h3″
.post h3 {margin:.25em 0 0;
padding:0 0 4px;
font-size:140%;
font-weight:normal;
line-height:1.4em;
color:$titlecolor;
}

.post h3 a, .post h3 a:visited, .post h3 strong {
display:block;
text-decoration:none;
color:$titlecolor;
font-weight:normal;
}

.post h3 strong, .post h3 a:hover {
color:$textcolor;
}
Change all of those codes with below,
.post .post-title {margin:.25em 0 0;
padding:0 0 4px;
font-size:140%;
font-weight:normal;
line-height:1.4em;
color:$titlecolor;
}

.post .post-title a, .post .post-title a:visited, .post .post-title strong {
display:block;
text-decoration:none;
color:$titlecolor;
font-weight:normal;
}

.post .post-title strong, .post .post-title a:hover {
color:$textcolor;
}
8. Save your template and done.

Now if you see your blog, it has the same look, but it has a better HTML structure now.

Tanara generatie

Astazi sunt foarte nervos. Stupefiat. Bulversat.
Totul a inceput ieri.

Eram in cantina firmei si mancam si eu ceva la micul dejun, discutand diverse cu colegii de serviciu.

Dintr-una intr-alta, am ajuns la lilieci. Stiti voi, soarecii aia cu aripi.
El: "Liliecii sunt foarte periculosi. Mai ales noaptea! Ca iti vad lumina de la tigara, si zboara drept in tine"
Eu: Glumesti, tinere. Ai auzit vreodata de Teleenciclopedia? Ca stiu ca de torenti cunosti destule. Se orienteaza prin emiterea de ultrasunete si receptarea ecoului reflectat de obiecte.
El: "Nu are cum, nu exista asa ceva. Pai ce, iti dai seama ca ei trebuie sa isi faca o harta in cap cu toate obiectele? Ce naiba, doar e vorba de un soarece, cat vrei sa tina minte in creier?"

Eu: confusedsurpriseatwitshandtimeoutlosersillyhypnonotlistenshameonyou. Si ar mai fii cateva.
Intr-un final... chatterl-am lasat in pacea lui. Chiar daca are peste 23 de ani.

Astazi discutam de un telefon, de fapt o stire care prezenta un telefon cu o autonomie de 1 an in standby, datorita bateriei care avea 16.8 amperi. Nu se stie insa daca traducerea din chineza a fost corect facuta.
El: "Putin. Nu zice ce voltaj are?".
Mai sar cativa colegi, care au sesizat ca e rost de mistocareala.
"Dar oare la priza cati amperi or fii?" intreaba unul. "50" raspunde altul. "Kilohertzi", raspunde primul tip, cu care am inceput povestea.
"Pai", zic eu, "ai atat cat ai nevoie, pentru ca totul se bazeaza pe transport si nu ai cum sa ai foarte mult pentru ca nu iti rezista cablurile, instalatia electrica. Gandeste-te ca in tabloul electric ai sigurante de 6, 10 sau 16 A (amperi) pentru un circuit. Deci nu ai cum sa consumi mai mult, pentru ca se arde siguranta (sau declanseaza, daca e automata)".

Altul zice ca monitorul lui consuma intre "8 si 10 A", ca asa scrie pe cablul de alimentare. confused

Primul tip: "Ma, nu amperajul te omoara, ci voltajul".
"Ok, zic eu, intr-adevar , in medii umede, cum este baia, periculos inseamna de la 25 de V in sus, dar asta pentru ca la priza nu ai un curent constant, sau o cifra standard. Curentul este de fapt raportul dintre Voltaj si Rezistenta electrica a corpului omenesc. Cunoscand Rezistenta, care este cateva mii de ohmi (2000-3000 in general) si avand o tensiune constanta, se afla repede amperajul (curentul consumat). De aceea e mai usor sa ne raportam la tensiune, pentru ca stim ca este o marime care poate fii constanta.

Pentru cititorii nostrii care nu prea cunosc asemenea detalii tehnice, sper sa ma puteti urmarii.

"Mai omule, ce facultate ai facut?" intreb eu. "Nu conteaza, stiu sigur ca e ca mine".
"Bun, dar pistoalele cu arc electric , folosite de politie, au vreo 90000 de volti. Cum de nu te omoara?"
"Mai, tu nu intelegi ca eu am dreptate si tu nu? Eu stiu sigur ca voltajul te omoara".

Mi-a fost rusine mie de impertinenta lui, de faptul ca atunci cand ai internetul la indemana si 4 oameni te contrazic, ai neobrazarea sa nu argumentezi cu dovezi, ci cu vorbe.

M-a "linistit" un coleg: "stai calm, asta e generatia care o sa ne conduca".
Din pacate, armele de foc sunt interzise in Romania. Chiar daca le folosesc ca sa ma sinucid, tot nu pot sa le cumpar legal.

Electrica si tiganii

De pe data de 1 Martie 2008, ca un cadou, au inceput sa fie in fiecare zi fluctuatii de tensiune. Mai mari, mai mici, mai dese... niciodata fara sa nu fie o cadere totala de tensiune. Nu tinea mult acea cadere, intre 0.5 si 2 secunde.

Chiar si 0.5 secunde de cadere de tensiune sunt in stare sa puna in protectie sursa calculatorului de pe care scriu acum.

Prima data am spus ca "deh, se mai intampla".
A doua oara am spus ca este o coincidenta.
A treia oara am inceput sa intru la banuieli. De ce? Pai din toate blocurile de pe strada, numai cel in care stau eu are problemele astea.

Probabil ca tiganii care locuiesc legal si ilegal in subsolul blocului au constatat ca vine primavara, asadar este cazul ca incalzeasca ceva apa sa se mai spele si ei.
Si mai probabil a fost ca atunci cand au conectat respectivele dispozitive de incalzit apa, adica resouri artizanale conectate si mai artizanal la reteaua electrica, in mod legal si ILEGAL dupa cum am mai spus, sa creeze un consum foarte mare sau un scurt-circuit.

Toate astea se intampla cam de 3-4 ori pe zi, dar mai des seara, cam pe la ora 8.
Se zice ca la ora aia este un varf de consum, pentru ca atunci se intoarce lumea de la serviciu.
Care dracu serviciu au tiganii astia ca toata ziua stau degeaba?

Pe data de 4 Martie 2008, la ora 20:30 (aproximativ), tensiunea electrica a scazut semnificativ, astfel incat cantitatea furnizata de becurile lustrei scazuse la jumatate. Acele becuri sunt de tip "ergonomic", cu un consum redus (2 becuri x 20W).
Acest tip de bec nu se poate folosi in instalatiile care folosesc variatoare de lumina, pentru ca sunt foarte insensibile (sau ar trebui sa fie) la modificarile de tensiune.

Am schimbat becurile normale cu incandescenta in urma cu o saptamana, cand fluctuatiile de tensiune generau un disconfort vizual prin schimbarile cantitatii de lumina furnizate.

Becurile economice instalate (un fel de neon) eu mai imbunatatit cat de cat situatia, astfel ca, atunci cand intensitatea luminoasa a scazut aproape de jumatate, dupa cum va spuneam, am banuit ca situatia nu este deloc roz.

Inainte sa pot opri calculatorul, a urmat o cadere totala de tensiune de circa 0.5 secunde, probabil cu o revenire spectaculoasa astfel incat sursa calculatorului a intrat in protectie.

Odata cu ea, lumina in camera a devenit foarte foarte intensa.
Am conectat un voltmetru digital la o priza din camera si nu mi-a venit sa cred: nu erau 220V asa cum era normal sa fie, nu erau nici 250V asa cum obisnuiesc furnizorii de energie electrica sa supraincarce reteaua.

Erau nu mai putin de 530V. Da, CINCI SUTE TREIZECI de VOLTI.


Am apucat sa filmez cateva minute inainte sa cada tensiunea inca o data.
Observati cei 527V, apoi cum se face intuneric, ca tensiunea sa revina la 400V si sa se mentina cel putin 15 minute.
Dupa aceasta poveste tensiunea a mai cazut o data, astfel incat 4 sigurante din tabloul electric s-au ars. Incercand sa le schimb, mi-au pocnit inca 2 sigurante in mana in timp ce le insurubam: in becurile economice s-a topit ceva astfel ca faceau scurtcircuit.

In ziua urmatoare, situatia caderilor s-a repetat de 4 ori in timpul zilei si inca o data la ora 22:00.

Cunoasteti o solutie de remediere a problemei astfel incat sa nu se mai repete? (de schimbat tabloul de control cu sigurante automate, schimbat prelungitoarele cu unele cu protectie si de cumparat un UPS pentru calculator ma voi ocupa eu)

Later edit: ghiciti ce s-a intamplat la 5 secunde dupa ce am scris acest articol?
Later later edit: au venit baietii de la Electrica pentru ca au fost prea multe persoane care au sesizat defectiunea. Dupa ce au dat din umeri, ca sa nu fie ciomagiti de aceeasi lume furioasa, au decis sa rezolve panoul electric al scarii si sa ii sudeze usile. Orice tentativa de deschidere a lor va fi considerata caz penal.

Abia astept!

Confirmari reuniune restransa - clasa D informatica

Salutare din nou.
Se pare ca mai multe persoane nu mai vor sa vina la reuniunea extinsa cu tot liceul ci vor doar o reuniune mai mica, a clasei noastre.

De aceea am mai facut si pagina asta, ca sa confirmam prezenta la o astfel de reuniune.
Daca ne vom strange suficienti, vom face [si] reuniunea doar cu clasa noastra, undeva mai prin iulie, asa cum a reiesit din votul vostru.

Suficienti inseamna doar fostii elevi ai clasei, nu si insotitorii lor. Daca vor fii si din acestia, cu atat mai bine, dar deaocamdata nu sunt luati in calcul.

Ca sa nu mai caut acum linkurile, reamintesc ca locatiile paginilor de confirmari si votul cu perioada reuniunii se afla in partea dreapta jos a paginii.

Confirmari prezenta reuniune restransa - doar cu clasa D informatica:

[confirmat] Catalin Zamfir
[confirmat] Adrian Luca
[confirmat] Aurel Barbulescu
[confirmat] Ciprian Valcea
[confirmat] Alexandru Bolborici


[infirmat] deocamdata nu am suficiente informatii
