In 2014, tasked with replacing a payment stack at a Paris-based startup, I found it surprisingly hard to evaluate payment processors due to unclear info and technical challenges. We eventually chose Stripe, even though it was brand new in Europe, thanks to its clear pricing, easy developer adoption, and straightforward documentation. Despite initial skepticism, Stripe is now a highly respected brand in tech and beyond. The key question now is how much of the financial stack Stripe will dominate going forward. Here’s a brief look at the key ingredients behind an outlier’s success.
Why Stripe Won
Disclaimer
I’m not a fan of “overnight success stories” because they overlook the hard work, resilience, and persistence involved. Stripe worked tirelessly to build a complete product, overcome trust issues, and navigate regulations—especially challenging when handling money flows.
Stripe picked the right “wave”
Stripe was founded in 2010 and definitely rode the e-commerce wave. The same year that Cyber Monday Sales in the US surpassed $1 billion. To give another example, in 2000, only 22% of Americans used a computer or phone to buy something online, whereas 80% of them did it in 2017. Stripe was picked by Shopify, and it definitely grew with the winners they were picking as customers. Although it seems to be obvious in hindsight (like all things in entrepreneurship), picking the right wave (powerful enough) at the right moment (before it becomes obvious), and matching its speed by paddling hard enough (ok I’ll stop the surf metaphors here) is a skill.
Stripe had an incredibly good taste
Stripe prioritized a group often overlooked in the payments industry: developers. Traditionally, payment processors were selected by finance teams, focusing on pricing, regulations, and coverage. Developers' input was rarely considered, even though a payment solution that wasn’t developer-friendly could lead to significant technical and business issues. Only experienced leaders understood that involving developers in the decision-making process was crucial to avoid long-term technical debt.
Stripe fully committed to the developer community, prioritizing the developer experience with strong conviction. While its documentation is highly praised, the true breakthrough was that developers could implement a payment system over a weekend, allowing businesses to start earning revenue quickly. This was a stark contrast to the traditional banking process, which involved multiple calls, extensive paperwork, and outdated technical documentation.
Stripe diversified the product offering early on, and Stripe Connect was a hit
Beyond expanding into Europe and Canada in 2013, Stripe also ventured into adjacent markets. They launched Stripe Atlas in 2015, helping global entrepreneurs set up U.S. businesses, and Stripe Radar, a fraud prevention tool. However, the standout product is Stripe Connect, which enables businesses to create their own payment platforms with minimal regulatory effort, effectively turning many into vertical SaaS providers. While payments are often commoditized, Stripe Connect's ease of use remains unmatched in the market.
Stripe showed extreme resiliency in 2022 and is now “gushing with cash”
According to The Information, Stripe reported around $615 million in free cash flow for the quarter ending in June, a major improvement from its $500 million cash burn in 2022. This figure exceeded the free cash flow of its rival Adyen for the first half of 2023. Stripe’s non-payments business, particularly billing software, has seen significant growth, with clients such as OpenAI, Atlassian, and Notion. The company expects its billing and tax software division to soon reach an annual revenue run rate of $500 million. Gartner recently recognized Stripe as a top provider in this space.
Stripe continues to switch gears and is eyeing software margins
At the Stripe Session in April 2024, several major updates were announced, with a strong focus on using AI to enhance payment systems and improve user experience. Some key announcements include:
AI-powered tools: Stripe introduced AI-driven upgrades like the "Optimized Checkout Suite," which personalizes payment methods for users, and new fraud prevention features through "Radar Assistant." This allows businesses to use AI to reduce fraud while minimizing false positives.
Modular Services: Stripe is opening up: Stripe made its core products—such as the Optimized Checkout Suite and Stripe Billing—available to companies using other payment providers. This modular approach provides flexibility for businesses looking to integrate specific Stripe features without overhauling their payment systems.
Revenue automation: Stripe also enhanced its revenue management tools, including the ability to support more B2B pricing models, in addition to the B2C and pure subscription models it catered to so far.
How far can Stripe go?
Stripe is expanding its focus from payments to financial software. It’s easy to envision Stripe becoming a leader in financial software, with payments evolving into more of a “loss leader” to drive adoption of other products. However, this raises some key questions:
Can Stripe’s software products stand on their own?
Would companies use them even if they don’t rely on Stripe Payments?
Recently, Stripe has focused heavily on billing, with major public announcements at Sessions, billboards in the Bay Area, and white papers. Stripe’s RFA products are projected to generate over $500 million in revenue. This rapid growth is clear, but a critical question remains: Despite their efforts, Stripe’s billing product is still playing catch-up with more specialized B2B billing solutions (example 1, example 2, example 3). Shifting from a product rooted in B2C and subscription models to one that serves B2B use cases is a significant transition that takes time. Stripe has moved quickly given its size, but competing priorities—unlike vertical specialists focused solely on billing, tax, or fraud—slow progress.
Stripe also entered the tax software space, launching Stripe Tax and acquiring TaxJar in 2021. TaxJar was meant to become a key part of Stripe’s revenue platform, but the two products are still marketed separately, with Stripe Tax positioned as “working better with Stripe Payments.” Meanwhile, specialized players like Avalara, Anrok, and Fonoa have continued to thrive, offering solutions compatible with multiple payment processors, including Stripe. This highlights the market opportunities that remain open, even after Stripe’s acquisition of TaxJar.
Pricing Structure: A Double-Edged Sword
Stripe is known for pricing its products with a percentage-based cut on revenue, including for software offerings. This strategy hasn’t seen significant changes, likely because it works for both Stripe and its customers. Modifying it could disrupt Stripe’s installed user base and negatively affect financial metrics—something the company would want to avoid ahead of an IPO.

How Open Can Stripe Be?
A recent focus for Stripe has been “extended interoperability”—allowing products like Stripe Billing and Stripe Radar to work with non-Stripe transactions. However, questions arise:
How far will Stripe go with interoperability?
Will they connect with processors requested by users, even if those processors are direct competitors?
Can Stripe balance openness with maintaining the value of its ecosystem without cannibalizing revenue?
Source: X fka Twitter
Stripe’s success is built on a closed ecosystem of interconnected products centered around payments. Even exporting Data outside the Stripe Ecosystem is a pain, except if you use "Stripe Data" products, more here. While these products work seamlessly within the Stripe environment, exporting data out of Stripe can be challenging. This raises concerns about how transparent and open they can be, especially when their users’ interests conflict with their own.
Here’s a slide from our Series A deck. While I’m an ex-McKinsey consultant (and not a fan of building slides, building companies is much more fun :) ), the design is simple because we weren’t actively fundraising at the time (full deck here).
We believe Stripe succeeded with its closed ecosystem strategy—a model that comes with trade-offs but undoubtedly fueled its growth. That said, we also see demand for an open and transparent approach:
Transparency and openness: Open-source and user-centric.
Interoperability from day one: Lago is tool-agnostic, allowing anyone to build connectors and prioritizing native integrations based on user requests.
Financial software-first: Users own and control their data, with the option to self-host instead of paying for Stripe Data Pipeline .
Is it bold, maybe even a bit crazy, to think alternatives to Stripe can succeed? Probably. But that’s the essence of entrepreneurship!

Abstract:Recent advances in multi-modal, highly capable LLMs have enabled voice-enabled AI agents. These agents are enabling new applications, such as voice-enabled autonomous customer service. However, with all AI capabilities, these new capabilities have the potential for dual use.
In this work, we show that voice-enabled AI agents can perform the actions necessary to perform common scams. To do so, we select a list of common scams collected by the government and construct voice-enabled agents with directions to perform these scams. We conduct experiments on our voice-enabled agents and show that they can indeed perform the actions necessary to autonomously perform such scams. Our results raise questions around the widespread deployment of voice-enabled AI agents.

Flox supports running services in your environment
Define services in your environment with flox edit and the new [services] manifest section.
Service configuration requires a command and, optionally, allows for a clean up shutdown.command in the event the process does not terminate with kill -SIGTERM. Use services that spawn a daemon by setting is-daemon = true.
Run services with flox activate --start-services or from within an already activated environment with flox services start.
Stop services with flox services stop.
View service logs with flox services logs and view live output with --follow or the most recent lines with --tail.
Use flox services restart to restart individual services or redeploy services after editing your environment.
flox services status allows you to see the status of your services as well as their process identifier (PID).
Exiting the last instance of an environment with running services automatically stops and cleans up running services.
This release also addresses several bugs and adds new improvements, including:
Fixed a bug with CUDA activation causing slow activations. (#1896, #1902)
Improved flox activate --help display (#1899)
VISUAL and EDITOR now support passing editor arguments split on whitespace (#1791)
The mobile navigation on the documentation site is much improved.

Replication? do it easily with TCapture
We are very glad to announce the compatibility with PostgreSQL 16 version.
TCapture is a bidirectional multi master replication server based on a 'capture and apply' asynchronous replica engine
The actual TCapture engine is a Java application which runs as a separate program outside "PostgreSQL" , and which must be started explicitly.
When TCapture is running, it will scan the transaction log of all primary databases and pick up transactions which must be replicated.
Transactions which have been picked up are stored in the 'store database' , a "PostgreSQL" user database exclusively used by TCapture.
In the store database, transaction is 'copied' to all store databases which have a subscription for this transaction.
Transaction is then applied to the replicate databases
One of the attractions of TCapture is that it’s quite easy to set up and configure: starting from scratch, you can deploy a working replication system in less than 30 minutes.
The setup procedure is described in the TCapture Guide. As always with replication, make sure you have a clear idea of the replication logic you want to implement before you start.
KEY FEATURE:
Transactional. SQL are captured transactionally, can be coupled with surrounding business logic.
Efficient. It capture transactions for replication from Write-Ahead Logs (WAL) instead of using triggers, eliminating overhead on master databases and significantly reduces latency
Flexible. No limits on the number of producers or consumers, but complexity increases
Reliable. Transactions are stored in "PostgreSQL" database – this adds the benefit of write ahead logging and crash recovery.
Transparent. No impact on the applications already running on that database, since both engine and 'store database' can run separate from production databases.
Easy to use. Simple to set up and configure, is an effective tool for data replication between different "PostgreSQL" versions
Open Source. No licensing fees, but occasionally you'll have to get your hands dirty

This approach leverages human language, codes, or phrases understood only by the involved parties.
Devices Involved<p><pre><code> Redmi 13: A Xiaomi smartphone configured for privacy.
Concrete: Disable call and SMS logs via phone settings or apps like CCleaner.
Turn off GPS and location services in Settings > Location.
Mobile X: A feature phone or simple smartphone.
Concrete: Use a basic model like Nokia 105 for minimal data retention, configured for calls and SMS only. Limit the contacts to just one labeled "13" for Redmi 13.
</code></pre>
SIM Information<p><pre><code> Anonymous SIM: Utilize a prepaid, non-registered SIM.
Concrete: Obtain these from regions where ID registration is not required, such as via SIMOptions or local shops in specific areas.
</code></pre>
Low-Metadata Setup<p><pre><code> Ensure minimal retention of data on both devices:
Concrete: Disable or auto-delete call logs using Call Log Monitor.
Limit app permissions for calls, messaging, and location through Settings > Apps > App permissions.
</code></pre>
Old-School Cryptography (Windtalker Style)<p>Use a private spoken or written code, incorporating elements similar to the original Native American code talkers’ approach, where the language or symbols are understood only by the communicating parties. This type of code ensures secure communication without reliance on modern encryption or software.
Overall Context<p>This approach ensures secure, low-metadata communication between two offline devices, using traditional, human-based codes for cryptography. The results will contribute to research on privacy-focused communication methods and will be shared publicly, providing insights into how historical cryptographic methods can be adapted for modern low-tech privacy needs. | null | 1 | 0 | null | null | null | null | null | null | null | null | null | null | train |

Special community version of Lakka has been released!
This special version is aimed at Raspberry Pi SBCs, namely Pi 3, Pi 4 and Pi 5. Out of the box these builds work with the composite video and analog audio outputs of these SBCs. In case of Pi 5 some soldering and a USB to 3,5 mm jack soundcard/dongle are required.
Release summary
This version of Lakka is set up to use analog video and audio outputs, so no changes after flashing the image are required. Two different versions of Raspberry Pi kernels have been used. Raspberry Pi 5 uses kernel 6.6.y, but Pi 3 and Pi 4 use kernel 5.10.y due to broken analog video output in kernel 6.6.y. RetroArch is updated to commit tagged 1.18.0 and all libretro cores are same version as latest v5.0 release. Mesa is at version 24.0.6.
Due to issues (hiccups and stutters) on the current release (Lakka-v5.x) and development (devel) branches, this community version is based on the Lakka-v4.x branch, where these issues are not present.
The community is grateful to all Raspberry Pi engineers and namely to njhollinghurst, who contributed latest updates to the driver for the RP1 VEC of the Pi 5 and provided detailed explanations and help in Raspberry Pi forums. Many thanks also to MegaManGB for hours of testing.
Currently only images with NTSC preset are available, but we will update this article with instructions for PAL users.
You can download the images from below links:
Raspberry Pi 3
Raspberry Pi 4
Raspberry Pi 5
Once updated images will be released with community fixes and updates, use the built-in online updater to download new updates.
Remember to configure each core individually to have an integer vertical height, which varies per core (like 224 or 240 for NES). And mainly use a tvout shader to horizontally even out / blur pixels and alleviate composite artifacting.
Update May 10th, 2024 / May 15th, 2024
We now include shader specially crafted for CRT televisions using composite input. Also most of the libretro cores are now preconfigured to run at the correct aspect ratio.
Here is a small demonstration from MegaManGB:
Wi-Fi configuration
You can edit wifi-config.txt to setup Wi-Fi network access after flashing the image and before the first boot. Just uncomment lines SSID= and PSK= and add your network name (SSID) and password (PSK). It is recommended to use standard characters for both, try to avoid asterisk, semicolon, backslash, spaces and quotes - single and double. You can still use RetroArch to connect to Wi-Fi network as usually, this only helps to set up the Wi-Fi network in advance.
PAL users
If you are using a PAL TV, you will need to edit and modify cmdline.txt and retroarch-overrides.txt in the FAT32 partition. Below are instructions for individual devices. These instructions are also included in the files as comments. In case of retroarch-overrides.txt you just need to uncomment those lines. In cmdline.txt the very first line has to be modified according to the instructions. Please keep in mind that no line breaks are allowed between the arguments - all arguments must be in single line.
RPi3 and RPi4:
In cmdline.txt change
video=Composite-1:720x480@60e vc4.tv_norm=NTSC-J
to
video=Composite-1:720x576@50e
In retroarch-overrides.txt add / uncomment following lines:
video_autoswitch_refresh_rate = "3"
video_refresh_rate = "50.08"
If you already installed Lakka (i.e. the first boot with partition resizing is already done), modify these options:
Settings → Video → Output →
change Vertical Refresh rate to 50.080 using left/right D-PAD on your gamepad or use the on-screen keyboard
change Automatic Refresh Rate Switch to OFF
Then save the settings (not needed if saving of settings on exit is enabled - default behavior) and restart RetroArch.
RPi5:
In cmdline.txt change
video=Composite-1:720x480,tv_mode=NTSC-J drm_rp1_vec.cmode=27000:721/16/64/58,480/6/6/34
to
video=Composite-1:720x576,tv_mode=PAL drm_rp1_vec.cmode=27000,721/12/64/68,576/4/6/38
In retroarch-overrides.txt add / uncomment following line:
video_fullscreen_y = "576"
It is very important to change the Y resolution before first boot, otherwise RetroArch will be not able start normally. If you happen to be in this situation, you have to edit the configuration file in /storage/.config/retroarch/retroarch.cfg (via ssh) or \\lakka-ip\Configfiles\retroarch\retroarch.cfg (via network share) and change the value of the key video_fullscreen_y to 576. After saving the file RetroArch should pick up the updated file and start normally.
Known issues
As this is a community release, there is no official support, but feel free to join the community on Discord (channel #lakkatv) using the invite link in the footer!

CNN
—
There aren’t many world champions who didn’t know their sport existed a year before winning the title.
But then, conkers isn’t like many other sports.
A traditional children’s game in Great Britain and Ireland, conkers players each hold a horse chestnut threaded onto a piece of string, taking turns to try and break the opponent’s nut with their own.
It is an explanation that Kelci Banschbach, who became the first ever American to be crowned world champion last month, has had to repeat multiple times to friends and family back in the US.
“It’s been a lot of, like, ‘Congratulations! I have no idea what this is, but good for you!’” she said in an interview with CNN Sport.
Originally from Indianapolis, Banschbach moved to Suffolk, England, for work and took up the game entirely by chance last year.
“Last fall, [I was] seeing all the conkers on the sidewalks and kind of wondering what they were,” she remembered. “So I just googled it, went down a rabbit hole on the Wikipedia page, and realized that it was a whole sport, it had rules, and that the championship was held just about an hour away.
“I just missed it last year, so myself and some co-workers, we kind of took it up in the office. Just kind of played it as a joke a couple times and planned to come this year.”
Right from the start, Banschbach’s talent was evident. “It’s kind of funny because I had won on two separate occasions, and kind of joked that I was the reigning conker queen.
“Little did I know that that would actually happen.”
‘An out-of-body experience’
Despite impressing among colleagues and traveling to Northamptonshire to attend the World Conker Championships, Banschbach did not originally intend to enter as a competitor.
“A friend of mine entered first,” said the 34-year-old. “I didn’t want him to be the only one, so I ended up kind of begrudgingly registering.”
Banschbach’s last-minute entry did mean that she missed out on one of the traditions of the tournament – competing in a costume.
“There was a man with a giant Yoda head. There was a guy that had sort of a papier-mâché conker shell,” she remembered. “I think my final opponent, she was a flight attendant. There was a Boy George.
“Lots of fun, random costumes… William the Conker-er!”
You would be mistaken for thinking, given the colorful outfits on display, that Banschbach’s opponents were just there for a relaxed day out.
“There was a three-time champion there. She was really intimidating to look at,” said the American. “Just knowing that she was successful, and she kind of had this stone face, like ‘Oh, she’s serious about this.’”
The crowd, about 2,000-strong, was no less hostile, even if it was all in jest.
“It was all in good fun. But I specifically remember the commentator would say something like ‘Oh, we’ve never had an American winner,’” said Banschbach. “And (the spectators) would shout, ‘And you’re never gonna have one!’”
How wrong they were. As the rounds went on, Banschbach grew stronger and stronger.
“Honestly, it kind of felt like an out-of-body experience. I didn’t feel like I was actually experiencing it. I was sort of watching it from outside of my body. Hard to explain, really.
“I think the momentum started flowing the further I got. I was getting more solid hits every round I progressed,” she continued.
“I was kind of in denial about it. I think the further I got, it was just like, ‘Wait, could I? Actually? No, I shouldn’t!’ But you know, we have an American saying, ‘Mama didn’t raise no quitter!’ I had made it that far, so might as well just keep on going!”
Before she knew it, Banschbach had won the women’s final and was facing off against competition veteran David Jakins, who first competed in 1977 and is known as “King Conker,” in the overall final.
The match lasted two or three minutes, a relative war of attrition in conker terms.
“We had some back and forth,” said Banschbach. “I actually got a pretty good crack in my conker, so I was kind of nervous that, you know, I would go out any second.
“His (conker) was kind of spreading further and further,” she continued. “That last solid hit just sort of exploded it.”
Kelci Banschbach, in her competitive conkers debut, had felled an icon of the sport.
“It was pretty euphoric, I’m not going to lie. I felt bad at the same time because David was a lovely guy, and I know it meant a lot to him to win it as well,” she remembered.
“There was some ‘U-S-A!’ chants in the background. So probably the closest I’ll get to any sort of big win at any stage in my life.”
The champion’s prizes for having pulled off such a feat and become the greatest in the land? A trophy, a dish towel, a tote bag and a coaster.
“I do have the trophy out on display. I brought it into work for a couple days, had to do a little victory round of the offices,” she laughed.
However, the victory was bittersweet. Due to move back to the US for work, Banschbach believes it is unlikely she will be able to defend her crown next year.
The 2025 Championships will likely attract an even larger crowd, after controversy overshadowed the men’s tournament this year. Jakins, who had never won the men’s competition previously, broke multiple opponents’ chestnuts with just one hit and was later found with a steel replica conker in his pocket.
He was later cleared of wrongdoing by the organizers, who said there was no evidence he had used the dummy nut, but the scandal had already made news around the world.
“I hope that I can somehow make it back next year because I do wonder if it’s going to draw a lot more people next year,” said Banschbach. “I would love to see that. I’ll just make a surprise cameo out of nowhere!
“Never say never! I won’t be living here anymore, but I’ll certainly try my best. Otherwise, I’ll see if I can convince some of my coworkers to uphold the American title.”

We all have 24 hours in a day.We all have a finite amount of willpower.We can only maintain so many relationships.Despite these limits, go-getters like myself keep trying to add new hobbies, interests, friendships, and activities into our lives. And we do so without consciously choosing what to subtract to balance the scales.This is a significant cause of stress in my life. I know I can't do it all, but I keep thinking maybe (just maybe) I can violate the laws of physics by multi-tasking harder.A more healthy approach is to acknowledge that something has to go. This is tough, particularly for someone who strives to keep commitments and not give up.In these situations, I need to give myself permission to purge.Were the habits I tried to form worth it?I'm working hard to keep this friendship, but have we both outgrown it?I started exploring this hobby. Am I enjoying it?My enthusiasm for starting something new has waned more often than not. While that's normal, it's healthy to reevaluate whether the juice is still worth the squeeze. If not, why keep going?I've had to cut a few things out of my life this week. None of them were big deals. However, by making it a conscious decision, I did not feel guilty or stressed about trying to keep the commitment any longer.I hope you give yourself permission to do the same for things that no longer serve you (or others). | 2024-11-08T12:50:13 | en | train |

We began with XMPP (eXtensible Messaging and Presence Protocol), but the need for interoperability and support for a variety of use cases led us to implement additional protocols. Our stack now supports:XMPP (eXtensible Messaging and Presence Protocol): A robust, highly scalable, and flexible protocol for real-time messaging.MQTT (Message Queuing Telemetry Transport): The standard for IoT messaging, ideal for lightweight communication between devices.SIP (Session Initiation Protocol): A widely used standard for voice-over-IP (VoIP) communications.Matrix: A decentralized protocol for secure, real-time communication.A Distributed Protocol That Replicates Data Across Federated ServersThis brings me to the topic of Matrix. Matrix is designed not just to be federated but also distributed. While it uses the term “decentralized,” I find this slightly misleading. A federated protocol is inherently decentralized, as it allows users across different domains to communicate–think email, XMPP, and Matrix itself. What truly sets Matrix apart from XMPP is its data distribution model.Matrix is distributed because it aims to ensure that all participating nodes in a conversation have a copy of that conversation, typically in end-to-end encrypted form. This ensures high availability: if the primary node hosting a conversation becomes unavailable, the conversation can continue on another node.In Matrix, a conversation is represented as a graph, a replicated document containing all events related to a group discussion. You can think of each conversation as a mini-blockchain, except that instead of forming a chain, the events create a graph.Resource Penalty: Computing and StorageAs with any design decision, there are trade-offs. In the case of Matrix, this comes with a performance penalty. Since conversations are replicated across nodes, the protocol performs merge operations to ensure consistency between the replicated data. The higher the traffic, the greater the cost of these merge operations, which adds CPU load on both the Matrix node and its database. Additionally, there is a significant cost in terms of storage.If the Matrix network were to scale massively, with many nodes and conversations, it would encounter the same growth challenges as blockchain protocols. Each node must store a copy of the conversation, and the amount of replication depends on the number of conversations and nodes globally. As these numbers grow, so does the replication factor.Comparison with XMPPXMPP, on the other hand, is event-based rather than document-based. It processes and distributes events in the order they arrive without attempting to merge conversation histories. This simpler approach avoids the replication of group chat data across federated nodes, but it comes with some limitations.Here’s how XMPP mitigates these limitations:One-on-One Conversations: Each user’s messages are archived on their server, keeping the replication factor under control (usually limited to two copies).Group Chats: If a chatroom goes down, the conversation becomes unavailable for both local and remote users. However, XMPP has strategies to reduce the need for data replication. Several servers implement clustering, making it possible to upgrade the service node by node. If one node is taken down (for maintenance, for instance), another node can take over the management of the chatroom.Hot Code Upgrades: Some servers, like ejabberd, allow hot code upgrades, which means minor updates can be applied without shutting down the node, minimizing downtime and the need for data replication.Message Archiving for MUC Rooms: Some servers offer message archiving for multi-user chat (MUC) rooms, but also allows users to store on their local server recent chat history in select MUC for future reference.Cluster Replication (ejabberd Business Edition): Chatrooms can be replicated within a cluster, ensuring they remain available even if a node crashes.Thanks to the typically high uptime of XMPP servers, especially for clustered services, intermittent availability of servers in the network hasn’t posed a significant issue, so large-scale data replication hasn’t been a necessity.What’s Next for XMPP?This comparison suggests potential improvements for XMPP. Could XMPP benefit from an optional feature to address the centralized nature of chatrooms? Possibly. What if there were a caching and resynchronization protocol for multi-user chatrooms across different servers? This could enhance the robustness of the federation without the storage burden of full content replication, offering the best of both worlds.What’s Next for Matrix?Matrix, by design, comes with trade-offs. One of its key goals is to resist censorship, which is vital in certain situations and countries. That’s why we believe it is worth trying to improve the Matrix protocol to address those use cases. There’s still room to optimize the protocol, specifically by reducing the cost of running a distributed data store. We plan to propose and implement improvements on how merge operations work to make Matrix more efficient.I’ll share our proposals in the next article: Thoughts on Improving Messaging Protocols — Part 2, Matrix.—As always, this is an open discussion, and I’d be happy to dive deeper into these topics if you’re interested.Feedback received:2024-10-25: I had envisioned the concept of automatic caching for MUC messages. However, there is an existing XEP that defines the behavior for federated MUC in XMPP: XEP-0289: Federated MUC for Constrained Environments. I am not aware of any implementations of this yet, but it’s a topic we are interested in exploring.

A healthy brain (fMRI image). Researchers are investigating the effects of stimulating regions of the brain linked to depression. Credit: Mark & Mary Stevens Neuroimaging and Informatics Institute/Science Photo LibraryA remote clinical trial involving more than 150 people has shown that an experimental treatment for depression — which uses a swimming-cap-like device to gently stimulate the brain — can be effective when carried out at home. The non-invasive therapy, known as transcranial direct current stimulation (tDCS), is designed to stimulate areas of the brain linked to mood regulation, and delivers a painless, weak electrical current through electrodes placed on the scalp. It could be a game-changer for the more than one-third of people with depression who do not respond to standard treatments such as antidepressants or psychotherapy.How deep brain stimulation is helping people with severe depressionThe trial, described on 21 October in Nature Medicine1, found that after ten weeks of regular treatment, participants who received tDCS showed a greater reduction in depressive symptoms than did those in a control group. Previous research has explored using tDCS to treat depression, but this study stands out for its long timescale and remote, home-based design, which did not require participants to make daily visits to a specialized clinic.“When we think about that aspect of barriers to mental health, accessibility is a huge one,” says Shawn McClintock, a clinical neuropsychologist at UT Southwestern Medical Center in Dallas, Texas, who was not involved in the study. The trial “really starts to substantiate the ability to take mental health treatments into a home setting”, he adds.Making brain cells fireIn the trial, researchers targeted the dorsolateral prefrontal cortex, a region of the brain involved in decision-making that is often less active in people with depression. “The tDCS involves a small current that makes it easier for the brain cells to discharge or to fire,” says study co-author Cynthia Fu, a clinical neuroscientist at King’s College London.Fu and her colleagues trained 120 women and 54 men, all of whom had been diagnosed with a major depressive disorder, to use the tDCS headset and randomly allocated people to either the treatment or a control group.Found: a brain-wiring pattern linked to depressionThose in the treatment group received a current of 2 milliamperes to the scalp — about 0.5% of the amount drawn by a 100-watt light bulb — for 30 minutes, 5 times a week for the first 3 weeks, then 3 times a week for 7 weeks. Participants in the control group wore a sham headset, which only delivered a brief pulse of current at the start of each session, mimicking the feeling of real tDCS without providing the same stimulation.After 10 weeks, the treatment group’s scores on a scale that measures depression symptoms dropped by 9.41 points, whereas the control group’s score decreased by 7.14 points. Nearly 45% of participants with the active tDCS device experienced reduction in or recovery from their symptoms, compared with almost 22% of those with sham device. The headsets were used in addition to other treatments — many of the study participants took antidepressants and enrolled in psychotherapy for at least six weeks prior to the study.Mixed resultsAlthough these results are encouraging, previous research has suggested that tDCS doesn’t work for everyone. Last year, for example, a study of 150 people found that tDCS did not have antidepressant effects2. But trials with positive and negative outcomes are both equally important to investigate the method’s potential as a treatment for depression, says Frank Padberg, a psychiatrist at Ludwig Maximilian University in Munich, Germany. The next step should be to understand why tDCS works for some people but not others, and to look for ways to personalize the treatment, he adds. “Different people need different dosages.”Future studies could also use brain imaging and electrical recording to observe changes in neural circuits during tDCS treatment in real time, says McClintock. This would help researchers to “see what this treatment is actually doing at the neural circuit level”.“Three decades ago, I wouldn't have thought that this stimulation does anything on the brain,” says Padberg. But now it is known that tDCS affects brain activity, “I'm pretty sure that an optimized method will make it to clinical care one day,” he says.

Both Russia and China have tested satellites with capabilities that include grappling hooks to pull other satellites out of orbit and “kinetic kill vehicles” that can target satellites and long-range ballistic missiles in space.
In May, a senior US defense department official told a House Armed Services Committee hearing that Russia was developing an “indiscriminate” nuclear weapon designed to be sent into space, while in September, China made a third secretive test of an unmanned space plane that could be used to disrupt satellites.
The US is far ahead of its European allies in developing military space capabilities, but it wanted to “lay the foundations” for the continent’s space forces, Saltzman said. Last year UK Air Marshal Paul Godfrey was appointed to oversee allied partnerships with NATO with the US Space Force—one of the first times that a high-ranking allied pilot had joined the US military.
But Saltzman warned against a rush to build up space forces across the continent.
“It is resource-intensive to separate out and stand up a new service. Even ... in America where we think we have more resources, we underestimated what it was going to take,” he said.
The US Space Force, which monitors more than 46,000 objects in orbit, has about 10,000 personnel but is the smallest department of the US military. Its officers are known as “guardians.”
The costs of building up space defense capabilities mean the US is heavily reliant on private companies, raising concerns about the power of billionaires in a sector where regulation remains minimal.
SpaceX, led by prominent Trump backer Elon Musk, is increasingly working with US military and intelligence through its Starshield arm, which is developing low Earth orbit satellites that track missiles and support intelligence gathering.
This month, SpaceX was awarded a $734 million contract to provide space launch services for US defense and intelligence agencies.
Despite concerns about Musk’s erratic behavior and reports that the billionaire has had regular contact with Russian President Vladimir Putin, Saltzman said he had no concerns about US government collaboration with SpaceX.
“I’m very comfortable that they’ll execute those [contracts] exactly the way they’re designed. All of the dealings I’ve had with SpaceX have been very professional,” he said.

] | null | null | no_error | Do You Really Need Redis? How to Get Away with Just PostgreSQL | 2021-02-04T13:00:07+00:00 | Chris Farber |
There’s a tried-and-true architecture that I’ve seen many times for supporting your web services and applications:
PostgreSQL for data storage
Redis for coordinating background job queues (and some limited atomic operations)
Redis is fantastic, but what if I told you that its most common use cases for this stack could actually be achieved using only PostgreSQL?
Use Case 1: Job Queuing
Perhaps the most common use of Redis I’ve seen is to coordinate dispatching of jobs from your web service to a pool of background workers. The concept is that you’d like to record the desire for some background job to be performed (perhaps with some input data) and to ensure that only one of your many background workers will pick it up. Redis helps with this because it provides a rich set of atomic operations for its data structures.
But since the introduction of version 9.5, PostgreSQL has a SKIP LOCKED option for the SELECT ... FOR ...statement (here’s the documentation). When this option is specified, PostgreSQL will just ignore any rows that would require waiting for a lock to be released.
Consider this example from the perspective of a background worker:
BEGIN;
WITH job AS (
SELECT
id
FROM
jobs
WHERE
status = 'pending'
LIMIT 1
FOR UPDATE SKIP LOCKED
)
UPDATE
jobs
SET
status = 'running'
WHERE
jobs.id = job.id
RETURNING
jobs.*;
COMMIT;
By specifying FOR UPDATE SKIP LOCKED, a row-level lock is implicitly acquired for any rows returned from the SELECT. Further, because you specified SKIP LOCKED, there’s no chance of this statement blocking on another transaction. If there’s another job ready to be processed, it will be returned. There’s no concern about multiple workers running this command receiving the same row because of the row-level lock.
The biggest caveat for this technique is that, if you have a large number of workers trying to pull off this queue and a large number of jobs feeding them, they may spend some time stepping through jobs and trying to acquire a lock. In practice, most of the apps I’ve worked on have fewer than a dozen background workers, and the cost is not likely to be significant.
Use Case 2: Application Locks
Let’s imagine that you have a synchronization routine with a third-party service, and you only want one instance of it running for any given user across all server processes. This is another common application I’ve seen for Redis: distributed locking.
PostgreSQL can achieve this as well using its advisory locks. Advisory locks allow you to leverage the same locking engine PostgreSQL uses internally for your own application-defined purposes.
Use Case 3: Pub/Sub
I saved the coolest example for last: pushing events to your active clients. For example, say you need to notify a user that they have a new message available to read. Or perhaps you’d like to stream data to the client as it becomes available. Typically, web sockets are the transport layer for these events while Redis serves as the Pub/Sub engine.
However, since version 9, PostgreSQL also provides this functionality via the LISTEN and NOTIFY statements. Any PostgreSQL client can subscribe (LISTEN) to a particular message channel, which is just an arbitrary string. When any other client sends a message (NOTIFY) on that channel, all other subscribed clients will be notified. Optionally, a small message can be attached.
If you happen to be using Rails and ActionCable, using PostgreSQL is even supported out of the box.
Taking Full Advantage of PostgreSQL
Redis fundamentally fills a different niche than PostgreSQL and excels at things PostgreSQL doesn’t aspire to. Examples include caching data with TTLs and storing and manipulating ephemeral data.
However, PostgreSQL has a lot more capabilities than you may expect when you approach it from the perspective of just another SQL database or some mysterious entity that lives behind your ORM.
There’s a good chance that the things you’re using Redis for may actually be good tasks for PostgreSQL as well. It may be a worthy tradeoff to skip Redis and save on the operational costs and development complexity of relying on multiple data services.
