Product Design Trends in 2024 | Teenage EngineeringsPixeldarts
The realm of product design is a constantly changing environment where technology and style intersect. Every year introduces fresh challenges and exciting trends that mold the future of this captivating art form. In this piece, we delve into the significant trends set to influence the look and functionality of product design in the year 2024.
How Race, Age and Gender Shape Attitudes Towards Mental HealthThinkNow
Mental health has been in the news quite a bit lately. Dozens of U.S. states are currently suing Meta for contributing to the youth mental health crisis by inserting addictive features into their products, while the U.S. Surgeon General is touring the nation to bring awareness to the growing epidemic of loneliness and isolation. The country has endured periods of low national morale, such as in the 1970s when high inflation and the energy crisis worsened public sentiment following the Vietnam War. The current mood, however, feels different. Gallup recently reported that national mental health is at an all-time low, with few bright spots to lift spirits.
To better understand how Americans are feeling and their attitudes towards mental health in general, ThinkNow conducted a nationally representative quantitative survey of 1,500 respondents and found some interesting differences among ethnic, age and gender groups.
Technology
For example, 52% agree that technology and social media have a negative impact on mental health, but when broken out by race, 61% of Whites felt technology had a negative effect, and only 48% of Hispanics thought it did.
While technology has helped us keep in touch with friends and family in faraway places, it appears to have degraded our ability to connect in person. Staying connected online is a double-edged sword since the same news feed that brings us pictures of the grandkids and fluffy kittens also feeds us news about the wars in Israel and Ukraine, the dysfunction in Washington, the latest mass shooting and the climate crisis.
Hispanics may have a built-in defense against the isolation technology breeds, owing to their large, multigenerational households, strong social support systems, and tendency to use social media to stay connected with relatives abroad.
Age and Gender
When asked how individuals rate their mental health, men rate it higher than women by 11 percentage points, and Baby Boomers rank it highest at 83%, saying it’s good or excellent vs. 57% of Gen Z saying the same.
Gen Z spends the most amount of time on social media, so the notion that social media negatively affects mental health appears to be correlated. Unfortunately, Gen Z is also the generation that’s least comfortable discussing mental health concerns with healthcare professionals. Only 40% of them state they’re comfortable discussing their issues with a professional compared to 60% of Millennials and 65% of Boomers.
Race Affects Attitudes
As seen in previous research conducted by ThinkNow, Asian Americans lag other groups when it comes to awareness of mental health issues. Twenty-four percent of Asian Americans believe that having a mental health issue is a sign of weakness compared to the 16% average for all groups. Asians are also considerably less likely to be aware of mental health services in their communities (42% vs. 55%) and most likely to seek out information on social media (51% vs. 35%).

5 Public speaking tips from TED - Visualized summarySpeakerHub
From their humble beginnings in 1984, TED has grown into the world’s most powerful amplifier for speakers and thought-leaders to share their ideas. They have over 2,400 filmed talks (not including the 30,000+ TEDx videos) freely available online, and have hosted over 17,500 events around the world.
With over one billion views in a year, it’s no wonder that so many speakers are looking to TED for ideas on how to share their message more effectively.
The article “5 Public-Speaking Tips TED Gives Its Speakers”, by Carmine Gallo for Forbes, gives speakers five practical ways to connect with their audience, and effectively share their ideas on stage.
Whether you are gearing up to get on a TED stage yourself, or just want to master the skills that so many of their speakers possess, these tips and quotes from Chris Anderson, the TED Talks Curator, will encourage you to make the most impactful impression on your audience.

3. Kas ir vienībtestēšana?
• Oficiāli:
– Metode, ko lieto atsevišķu programmatūras
koda daļu pārbaudei, vai tās darbojas
saskaņā ar specifikāciju.
– Testē mazāko iespējamo koda vienību
• klases metodi
• moduļa funkciju
• Vienkāršotā izpratnē
– Testi, ko raksta pats programmētājs
4. Galvenie mērķi
• Pārliecināties, ka
– kods dara to, kas paredzēts
– labojumi kodā (t.sk. refaktorēšana) nesabojā
kaut ko citu
• Uzlabot koda kvalitāti pirms integrācijas
testēšanas
• Padarīt kodu uzturamu arī citiem
• Automatizācija
5. Vienībtestēšana VS integrācijas
testēšana
• Vienībtesti nav integrācijas testi!
– Integrācijas testi apskata vairāku moduļu
sadarbību vai visu sistēmu kopumā
– Vienībtests pārbauda katru moduli atsevišķi
Vienībtests:
- vai šim vītnes
platums
visur ir vienāds?
http://www.bolt-manufacturer.com/picture/hex-bolts/heavy-hex-bolt.jpg
Integrācijas tests:
- vai ar šo var uzspiest līdz 45?
http://inhabitat.com/files/mowercycle23.jpg
6. Ko nozīmē "katru moduli
atsevišķi"?
• Vienībtestā jācenšas izolēt pārbaudāmo
moduli no citiem moduļiem
• Kļūdu gadījumā gribam zināt, kas tieši
vainīgs
• Lai izolētu no pārējiem moduļiem, lieto
imitācijas (mock) un aizbāžņus (stub)
saistīto moduļu vietā
7. xUnit
• xUnit: vienībtestēšanas ietvaru saime
dažādām valodām, kas
– izmanto programmatiskus testus
– lieto vienus un tos pašus jēdzienus
• Vēsturiski pirmais ir SUnit (SmallTalk unit
testing framework)
• Vēlāk arī JUnit (Java), CPPUnit (C++),
NUnit (.Net saimes valodas), PHPUnit.
8. xUnit termini
• Testu kopa (test suite)
– Atsevišķi testi, ko izpilda moduļa funkcionalitātes
pārbaudei
– Pārbaude kādam koda modulim (piemēram, klasei
DateTime būtu testu kopa DateTimeTest)
• Testpiemērs (test case)
– Tests, ko izpilda kādas funkcionalitātes pārbaudei
• Testa konteksts (test fixture)
– Datu/vides sagatavošana testu izpildīšanai
• Testu izpilde (test execution)
– Testu darbināšana dotajā kontekstā
• Apgalvojumi (assertions)
– Kodā pierakstāmi pieņēmumi, kam jābūt spēkā pirms/pēc
koda izpildes
• http://www.martinfowler.com/bliki/Xunit.html
9. xUnit testu kopas uzbūve
public class SomethingTest inerhits Test {
//sagatavošanās ('fixture')
public void SetUp() {
}
//savākšana aiz sevis
public void TearDown{
}
//paši testi
public void TestMethod1(){}
public void TestMethod2(){}
...
}
10. xUnit testu izpildes principi
• Meklē visas testu kopas
• Katrā testu kopā meklē visas metodes, kas
sākas ar "Test"
• Katrai šādai metodei izpilda:
SomethingTest->SetUp();
SomethingTest->TestMethod1();
SomethingTest->TearDown();
SomethingTest->SetUp();
SomethingTest->TestMethod2();
SomethingTest->TearDown();
11. Vienībtestēšanas maksimums
• Nopietnākais vienībtestēšanas lietojums –
testu bāzētā izstrāde (test driven
development)
– specificē moduļu interfeisus
– raksta testus, kas pārbauda šos interfeisus
– tikai tad sāk rakstīt pašu kodu
• Sākotnēji visi testi būs "izlaisti" vai "failed"
• Beigās būs strādājoša sistēma un 100%
veiksmīgi testi
15. PEAR: kas tas tāds?
• PEAR: PHP Extension and Application
Repository
• Ideja: komdandrindas rīks, kas ļautu instalēt
PHP paplašinājumus
• Uzlikšana:
1. iedarbina PHP komandrindas interfeisu
2. lejuplādē http://pear.php.net/go-pear.phar
3. php go-pear.phar
4. pārstartē tīmekļa serveri
• Var gadīties, ka noder
pear upgrade --force PEAR
16. Kas ir Xdebug?
• PHP ir skriptēšanas valoda, tas izpildās
kāda procesa ietvaros (tīmekļa serverī,
komandrindā)
– "klasiska" atkļūdošanas pieeja, kur pieslēdzas
procesam, būtu sarežģīta
• Xdebug ir PHP modulis, kas
– darbojas PHP interpretatora iekšienē
– uz ārpusi sniedz atkļūdošanas informāciju
– darbojas kā HTTP serviss
17. XDebug uzlikšana
• Xdebug ir PECL modulis
• Instalējams ar PEAR/PECL:
– pecl install xdebug
• Ini failā papildus:
[xdebug]
zend_extension=/Applications/XAMPP/xamppfiles/lib/php/php-
5.3.1/extensions/no-debug-non-zts-20090626/xdebug.so
xdebug.remote_enable=on
xdebug.remote_handler=dbgp
xdebug.remote_host=127.0.0.1
xdebug.remote_port=9000
18. PEAR uz XAMPP/Wamp
• XAMPP
– Jaunākās versijas ir ar PEAR,
– Xdebug jāinstalē pašiem
• WampSever
– Vecākās versijās PEAR var būt jāliek pašiem
– Xdebug vajadzētu būt
19. Xdebug atbalsts
• NetBeans – kopš 6.versijas integrēts
atbalsts
• Notepad++ var iekonfigurēt:
– http://dowdrake.com/showthread.php?343-
Xdebug-with-WAMPServer-and-Notepad
23. PHPUnit + ietvari?
• Zend
– Atbalsts jau iekļauts ietvarā
– http://framework.zend.com/wiki/display/ZFDEV/Testing+St
andards
• CodeIgniter
– Atbalsta ietvarā nav (ir slikts), ir 3. puses risinājums
– http://jensroland.com/projects/toast/
• (nav PHPUnit, bet esot labs)
– https://bitbucket.org/kenjis/my-ciunit/overview
– https://gist.github.com/1142213
• Symfony
– Ir spraudnis: http://www.symfony-
project.org/plugins/sfPhpunitPlugin
25. Failu struktūra
• Labā prakse ir katru (īstā) koda klasi likt
atsevišķā failā
• Katrai klasei "atbilst" ir sava testu kopa
• Tipisks risinājums: saknes katalogā veidot
apakškatalogu "tests" ar līdzīgu struktūru
īstajai
/
/common_includes /test
/database
/exporters /common_includes
/test /database
/exporters
26. Testa kopas struktūra
<?php
class ManaKlaseTest extends PHPUnit_Framework_TestCase {
protected $object; //testējamās klases instance
protected function setUp() {
$this->object = new ManaKlase();
}
protected function tearDown() {
unset($this->object);
}
public function testMetodesPasauksana() {
$this->object->PasauktMetodi();
$this->assert...();
}
27. Ko rakstīt testpiemēros
• Katrai metodei raksta vienu vai vairākus
testpiemērus
• Testpiemērs pasauc kādu funkciju un fiksē
apgalvojumus, kam jābūt spēkā pēc
izsaukšanas
• Labais stils – viens apgalvojums uz vienu
testpiemēru
28. Apgalvojumu veidi
• visi apgalvojumi ir
PHPUnit_Framework_TestCase metodes.
Tāpēc $this->assert..
• assertEquals(what1, what2);
• assertTrue(), assertFalse()
• assertGreaterThan(); assertLessThanOrEqual();
• assertStringStartsWith(); assertSelectRegexp();
• + daudz citu:
http://www.phpunit.de/manual/3.6/en/writing-tests-for-
phpunit.html#writing-tests-for-phpunit.assertions
29. Atkarības
• Var gadīties, ka nav jēgas pildīt testu
B, kamēr nav veiksmīgs tests A
• Tad testam B lieto atribūtu @depends
/**
* @depends testA
*/
public function testB(){
}
30. Datu piegādātāji
• Ir labi veikt testus ar dažādu ievaddatu
kopu
• Nav prātīgi visus ievaddatus "iešūt kodā"
• "Atpārošana" (decoupling) iespējama,
izmantojot @dataProvider atribūtu
• Piegādātājs = metode, kas atgriež testa
datu masīvu
• Piemēros parasti izmanto array(), praksē
varētu nolasīt no DB.
31. Datu piegādātāji – piemērs
class DataTest extends PHPUnit_Framework_TestCase
{
protected static $myData = array(
array(0, 0, 0),
array(0, 1, 1),
array(1, 0, 1),
array(1, 1, 3)
);
public static function provider()
{
return self::$myData;
}
/**
* @dataProvider provider
*/
public function testAdd($a, $b, $c)
{
$this->assertEquals($c, $a + $b);
}
}
32. Kas traucē vienībtestēšanai?
• Jebkas, kas padara testu specifisku
konkrētajam izpildes brīdim vai izsaukumam:
• Globālie mainīgie
– to uzstādīšana traucē veikt tīru testu
• "Singleton" pieeja
– Ir radniecīgi globālajiem mainīgajiem
• Biznesa darba veikšana konstruktorā
• Atkarība no datiem DB vai failu sistēmā
• Koda konstrukcijas:
– privātie & aizsargātie mainīgie
