BitWarden

Open source password management solution, can be self-hosted (how-to)
Integrates with Ansible.

1Password

A cloud-hosted password manager. No longer recommended, as it has regressed into an Electron application mandating remote storage of your password vault.

KeePass

Free, open source, light-weight, and easy-to-use password manager.
These slides discuss the why? how? what? where? of KeePass (presented by F. Morsbach at the first CryptoParty in Uppsala, 2019)

KeePass is written in C# and therefore requires Microsoft's .NET platform.

• Plugins: A list of third-party plugins for KeePass
• Android: Keepass2Android
• iPhone: MiniKeePass
• Chrome / Firefox: Tusk
• Web App: KeeWeb

KeePassXC

Open source, cross-platform.
KeePassXC is developed in C++ and runs natively on all platforms.

• Easy to achieve cloud sync by simply storing your KeePassXC database inside your shared cloud folder (using Nextcloud, for example).

AuthPass

AuthPass supports the KeePass database (KDBX format).
Setup instructions.

Pass

Simple GPG/Git password manager. Adheres to the Unix philosophy, which makes it easy to integrate with anything, e.g., Ansible.
This is my password manager of choice :-)

• Excellent in combination with rofi or dmenu on the Linux desktop, and
• on Android, useable with a combination of Password Store and OpenKeychain.
• Rich ecosystem of plugins, tools: pass-rotate.
• Clever uses of pass, by Vikaly Parnas.

Dashlane

"An intuitive password manager with over with over 8 million users worldwide."
Not open source, as far as I know.

Passbolt

Free, open source, self-hosted, extensible, OpenPGP based.

LessPass

Stateless, open source password manager.

Psono

Open source and self-hosted password manager for teams.

Buttercup

Another open source password manager with desktop, mobile, and browser clients.

LastPass

One of the most widely-used password managers, but that does not mean it's the best. Parent company is LogMeIn. Completely cloud-based, and not open source, obviously. On that basis alone, I do not recommend it. LastPass has suffered a major breach, it is now effectively dead.

Password manager apps that integrate with Nextcloud?

• Keeweb for Keepass
• Enpass
• Passman
• Passwords, native Nextcloud app

Färre bilskjutsar gav tryggare skolväg och piggare barn.
Via Cyklistbloggen.

Författaren bakom studien, Anna-Karin Lindqvist, universitetslektor vid Luleå tekniska universitet, har deltagit i ett avsnitt av Cykelfrämjandets poddcast: "Utmaningen är inte barnen – det är föräldrarna".

Endast omkring 30% av svenska barn når rekommendationen för fysisk aktivitet och bara hälften av barnen använder aktiva skoltransporter. Förutom den samhälleliga utmaningen som detta innebär för barns hälsa och kognitiv förmåga, har det också en negativ inverkan på klimatet och trafiksäkerhet nära skolorna. Dessutom följer barns fysiska vanor med in i vuxenlivet och därmed har den fysiska inaktiviteten på sikt en betydande hälsoekonomisk negativ effekt.

Hennes forskningsprojekt "Aktiva skoltransporter" går att läsa om i flera vetenskapliga artiklar men har även lett till publikationer i flera tidningar/bloggar:

Kairo har närmare 20 miljoner invånare och bedömdes av Världshälsoorganisationen WHO år 2018 att ha de näst värsta luftföroreningarna i världen.
Enligt tidningen Egypt Independent fokuserade diskussionerna mellan Kamel al-Wazir och Volvo på ett projekt som innebär att etablera ett BRT-system på ringleden i Kairo i samband med att leden byggs ut med fler körfält.

SKR beräknade i fjol att det behöver byggas över 700 förskolor fram till år 2022.

Replacing Youtube altogether

Another approach is to replace Youtube with an open-source, federated video host service.
That would be PeerTube (see this blog post by LazyBear).

From Patrick Collison's review:

World Bank data indicate that 3.7 billion people, about half the world’s population, are exposed to more than 50 µg/m³ of PM2.5 on an annual basis, 5x the unit of measure for most of the findings below.

• Substantial declines in short-term cognitive performance after short-term exposure to moderate (median 27.0 µg/m³) PM2.5 pollution: “The results from the MMSE test showed a statistically robust decline in cognitive function after exposure to both the candle burning and outdoor commuting compared to ambient indoor conditions. The similarity in the results between the two experiments suggests that PM exposure is the cause of the short-term cognitive decline observed in both.” […] “The mean average [test scores] for pre and post exposure to the candle burning were 48 ± 16 and 40 ± 17, respectively.” – Shehab & Pope 2019.
• Chess players make more mistakes on polluted days: “We find that an increase of 10 µg/m³ raises the probability of making an error by 1.5 percentage points, and increases the magnitude of the errors by 9.4%. The impact of pollution is exacerbated by time pressure. When players approach the time control of games, an increase of 10 µg/m³, corresponding to about one standard deviation, increases the probability of making a meaningful error by 3.2 percentage points, and errors being 17.3% larger.” – Künn et al 2019.
• A 3.26x (albeit with very wide CI) increase in Alzheimer’s incidence for each 10 µg/m³ increase in long-term PM2.5 exposure? “Short- and long-term PM2.5 exposure was associated with increased risks of stroke (short-term odds ratio 1.01 [per µg/m³ increase in PM2.5 concentrations], 95% CI 1.01-1.02; long-term 1.14, 95% CI 1.08-1.21) and mortality (short-term 1.02, 95% CI 1.01-1.04; long-term 1.15, 95% CI 1.07-1.24) of stroke. Long-term PM2.5 exposure was associated with increased risks of dementia (1.16, 95% CI 1.07-1.26), Alzheimer’s disease (3.26, 95% 0.84-12.74), ASD (1.68, 95% CI 1.20-2.34), and Parkinson’s disease (1.34, 95% CI 1.04-1.73).” – Fu et al 2019. Similar effects are seen in Bishop et al 2018: “We find that a 1 µg/m³ increase in decadal PM2.5 increases the probability of a dementia diagnosis by 1.68 percentage points.”
• A study of 20,000 elderly women concluded that “the effect of a 10 µg/m³ increment in long-term [PM2.5 and PM10] exposure is cognitively equivalent to aging by approximately 2 years”. – Weuve et al 2013.
• “Utilizing variations in transitory and cumulative air pollution exposures for the same individuals over time in China, we provide evidence that polluted air may impede cognitive ability as people become older, especially for less educated men. Cutting annual mean concentration of particulate matter smaller than 10 µm (PM10) in China to the Environmental Protection Agency’s standard (50 µg/m³) would move people from the median to the 63rd percentile (verbal test scores) and the 58th percentile (math test scores), respectively.” – Zhang et al 2018.
• “Exposure to CO2 and VOCs at levels found in conventional office buildings was associated with lower cognitive scores than those associated with levels of these compounds found in a Green building.” – Allen et al 2016. The effect seems to kick in at around 1,000 ppm of CO2.
