andysinclair··on Talking to the robots (my first encounter with an AI agent)
Thought I would write a quick blog post on my first encounter with an AI agent in the wild. The first of many I presume...
andysinclair··on Ask HN: Those making $500/month on side projects in 2025 – Show and tell
Looks really good, will try it.

What is your revenue split, tip vs non tips? I've always wondered if putting a tip button on a free app could generate significant income.

andysinclair··on Microsoft Copilot AI Comes to LG TVs, and Can't Be Deleted
I am still using my ancient Pioneer plasma and dreading the day it dies.

Any recommendations for a ≈42 inch dumb screen replacement for when that day arrives?

andysinclair··on ChatGPT Atlas
and there is Copilot for Edge which no one uses.

It can also summarize pages, scale recipes etc.

andysinclair··on Seven Engineers Suspended After $2.3M Bridge Includes 90-Degree Turn
There's a bridge with TWO 90-degree turns in Athens, Greece. I've always thought it was an odd design: https://maps.app.goo.gl/j4hzcGKH8b2XdFbJ8
andysinclair··on A non-technical explanation of deep learning
He’s saying that the spreadsheet represents the “picture” of the cat in terms of pixels and RGB values etc.

The algorithm/workers are not really “looking” at a picture of a cat, they are analysing and looking for patterns in the data that defines the picture of the cat.

andysinclair··on Show HN: I've built a C# IDE, Runtime, and AppStore inside Excel
What did you use to write the installer, and how do you determine if the targeted version of Excel is 32 or 64 bit?

I've built an Excel-DNA based Add-in (https://www.excelpricefeed.com/) and distribute it via an installer built using Advanced Installer. It works well, the only real pain point is the the user has to find out which version of Excel they have installed in order to choose the correct download (32 or 64 bit).

Do you know if this item from the Microsoft 365 roadmap would stop Add-ins (xll files) like this from working?

https://www.microsoft.com/en-us/microsoft-365/roadmap?filter...

I also have a vested interest as one of my software products is an xll Add-in. Any further details from Microsoft would be most welcome, thanks.

Looks great, will give it a try (as a fellow Excel developer).

One small point: on your webpage the "Try QueryStorm out" button on the "Start a free trial" panel just points to: https://querystorm.com/csharp-in-excel/ rather than the generate key page.

andysinclair··on Sam Altman’s Worldcoin wants to scan eyeballs in exchange for crypto
I had to check the date of the article to make sure it wasn't April 1.
andysinclair··on Sam Altman’s Worldcoin wants to scan eyeballs in exchange for crypto
$1 billion valuation and $25m in funding for a database and 30 prototype orbs (aka cameras which can scan an eyeball).

The world has gone mad.

andysinclair··on Coinbase S-1
-We have applied to list our Class A common stock on the Nasdaq Global Select Market under the symbol “COIN.”

This in itself will probably add a few billion in market cap...

andysinclair··on Tesla buys $1.5B in Bitcoin, may accept it as payment in the future
How does this square with Tesla's "green" mission?

Bitcoin consumes annually the electricity output of a small country. Surely if they were serious about tackling environmental issues they would not be investing in Bitcoin?

This news itself has pushed the price up over 15% today and no doubt enables another warehouse full of machines to start working 24/7 to mine more bitcoin...

andysinclair··on Tesla buys $1.5B in Bitcoin, may accept it as payment in the future
Here is the key paragraph from todays 10k. It also mentions gold related assets. (https://www.sec.gov/Archives/edgar/data/1318605/000156459021...):

"In January 2021, we updated our investment policy to provide us with more flexibility to further diversify and maximize returns on our cash that is not required to maintain adequate operating liquidity. As part of the policy, which was duly approved by the Audit Committee of our Board of Directors, we may invest a portion of such cash in certain alternative reserve assets including digital assets, gold bullion, gold exchange-traded funds and other assets as specified in the future. Thereafter, we invested an aggregate $1.50 billion in bitcoin under this policy and may acquire and hold digital assets from time to time or long-term. Moreover, we expect to begin accepting bitcoin as a form of payment for our products in the near future, subject to applicable laws and initially on a limited basis, which we may or may not liquidate upon receipt."

andysinclair··on GameStop (Wall St vs. Main Street)
I thought I would write up an explanation of what is currently going on with GameStop, in what could be a defining moment for the world of finance.

I hope some of you find it interesting and informative!

andysinclair··on Show HN: Forexbook – Automated trading journal that syncs with Metatrader
Thanks for the reply.

I have a product in the trading/investing space. What is your plan to get your product in front of potential customers? I find this the hardest part of building/launching a product.

andysinclair··on Show HN: Forexbook – Automated trading journal that syncs with Metatrader
Whilst stock trading enables you to bet on the price/performance of a company, forex trading enables you to bet on the price/performance of a country/currency.

You bet, however, not on a single currency but on a currency pair so you are really betting on how one currency will perform against another currency.

andysinclair··on Show HN: Forexbook – Automated trading journal that syncs with Metatrader
Looks interesting although there is no indication of who runs the website, who built it etc.

I always look for an "About Us" page before signing up for anything like this.

andysinclair··on Apple Announces App Store Small Business Program
This is not aimed at solving your problem, this is aimed at helping us small developers build a more sustainable business on the App Store.

We will ultimately build more apps and invest more time in supporting and improving our current apps.

andysinclair··on Show HN: Cashbar app – your SaaS revenue in your menu bar
Me too, although currently the lowest resolution of reports from Apple via the API is daily sales, no way to get last 24 hours at the moment (which I would be most interested in).
andysinclair··on The Touchscreen Infotainment Systems in New Cars Are a Distracting Mess
> The other big disadvantage is the failure mode: if the screen fails, a whole set of functionality becomes inaccessible

Yep, the touch screen in my car cracked recently and the AC got stuck on a very low setting and was constantly blowing out cold air - there was no way to adjust it without using the screen.

It is not only the single point of failure that is annoying but the fact that to control the AC you need to use the touch screen in AC mode which mean switching from GPS mode or radio mode etc. Very distracting when driving.

Car designers: Please give us more knobs!

andysinclair··on Show HN: Excel Price Feed – Live and Streaming Financial Prices in Excel
Developer here: I’ve built an Excel Add-In which feeds live financial data to cells via simple formulas. It currently sources data from Yahoo Finance and IG Index, I am working on other data providers.

For example to populate a cell with the latest Apple stock price: =EPF.Yahoo.Price(“AAPL”)

For brokers, such as IG Index you can download historical data for analysis, submit trades and stream real-time prices to cells.

I have some users using it to automatically keep track of the value of their portfolio across different brokers and I'm also helping one guy working on an automated trading system in Excel.

Here's a tutorial on using it to build a realtime investment portfolio. https://www.excelpricefeed.com/tutorials/excel-realtime-stoc...

You can try it free for 10 days at https://www.excelpricefeed.com

Would love to get some feedback!

andysinclair··on Developing for Android is like being a demonetized YouTuber
Interesting...is the app exactly the same on both platforms and the same price (assuming it is paid)?

I am interested to see if it's worth porting some of my iOS apps to Android.

andysinclair··on Show HN: Stock Screener and Portfolio Management for DIY Equity Investors
Looks like you need to specify number of shares AND a cost.

If you just set a number of shares it is ignored, there should be a warning.

Looks good though, really needs a refresh button on the portfolio screen to update with latest prices.

andysinclair··on The Psychological Trap of Freelancing
It is better if you can charge on a 'per project basis' but only if you have spent time up front working on an accurate estimate and, more importantly, built in significant contingency into your price.

Often though this up front time working on an estimate can end up being for free, an opportunity cost really, if you don't win the project.

andysinclair··on Ask HN: What are some hacks of real founders who did things that don't scale?
I like “Artificial Artificial Intelligence”.
andysinclair··on Ask HN: Should I abandon a functioning SaaS with no paying users?
I think you need to work on SEO, I just Googled "facebook page to website" and your site did not appear in the first few result pages. I'm afraid the top hit was PageVamp which seems to provide exactly the same service, is cheaper and provides more features.

Edit to add: Maybe adding some side-by-side examples would help? i.e. where you can see the Facebook page along side the synchronized website.

andysinclair··on Ask HN: Anyone designs financial engineering tools as a hobby?
Looks good. If you don't mind me asking, what did you use to build you web application (at https://terminal.quantra.io/)?
andysinclair··on Machine Learning and AI at Microsoft Build 2018
I wrote this post to keep track of all the AI/ML content that came out of the Build conference last week. Hope somebody else finds it useful!
andysinclair··on Dropbox hit the public market Friday, surging above $30 in its opening trades
Interesting to see the price action (and reaction) during the first few moments of trading.
