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.

2. Derin Paket Teftişi
• Bilgisayar ağı paketlerinin başlık ve yük
kısımları dâhil tamamının çözümlenmesi ve
paket ile ilgili uygulamanın belirlenmesi için
birden çok paketin çaprazlama bilgilerinin
ilintilendirilmesidir.
• Sığ Paket Teftişi: Sadece paket başlığı teftiş
edilir.

3. Mektupların İçlerine Bakmak
• Normalde zarfların üzerindeki bilgiler, bir
mektubun alıcıya ulaşması için yeterlidir.
– Paketlerdeki başlık bilgileri de buna benzer.
• Ancak paketin asıl yükünü (faydalı – fena)
görmek -yani derin paket teftişi- mektupların
içine bakmaya benzetilebilir.

On the other hand, the data gleaned from deep packet inspection can be used for darker purposes. ISPs in China use deep packet inspection for censorship -- scanning for certain keywords and blocking access to particular websites. Back in 2008, a US company called Phorm attempted to launch an ad-targeting system in the UK which would intercept users web surfing habits and datamine them for information to sell to advertisers.

It caused a storm of controversy, eventually culminating in the European Commission beginning legal action against the British government for permitting the service to operate. The case was only closed again in January 2012, after the UK amended its laws to include a sanction on unlawful interception of communications.
Many ISPs also use the technology to lower the priority of traffic from filesharing networks at peak times (known as traffic shaping), and the creative industries have called for it to be used as a weapon in their crusade against filesharing, using the same filters currently used to block child pornography to stop consumers watching questionably-obtained TV shows.
There are two major issues with deep packet inspection, however. The first is that it might not be legal, and the second is that it's trivial to circumvent.
The Regulation of Investigatory Powers Act 2000 (which is the act that was amended following the European Commission's legal action) clearly states that the interception of telecommunications is an offence if transmissions are monitored "as to make some or all of the contents of the communication available, while being transmitted, to a person other than the sender or intended recipient of the communication". Given that the uniqueness of the information gathered through deep packet inspection is enough to build up a profile of usage data, one could argue that this constitutes "interception" and is therefore a criminal offence. However, the language in the act is broad and so far, there's little precedent on either side.
As for the second problem, there are hundreds of services on the web offering encryption for your communications. It's far harder for deep packet inspection systems to dig into secured communications, so if you can create a secure "tunnel" between your computer and a server outside your ISPs network (known as a VPN, in this case), then any data that you send through will be much more difficult (read: not really worth the hassle, unless you're doing something seriously illegal) for your ISP to access.
Ultimately, there are both perfectly legitimate and very troublesome applications of deep packet inspection technology. It makes your Skype calls and YouTube videos play smoothly, and stops your grandparents getting a virus on their laptop, but it can also be used by ISPs selling your data to advertising companies or to block you from accessing certain, politically-troublesome, websites.
