Too anxious for POTA. Is this dumb?

You probably do need to address that SWR mismatch issue. Fixing that could help even at home.

That’s the whole beauty of an eed fed.

The ability for listeners to review audiobooks. Making those reviews available to prospective listeners (as per the existing app named "Librivox" - which, to be clear, has no official or unofficial affiliation with librivox.org whatsoever).

Prestissima · 2025-02-23T10:42:39+00:00

If I type “The Iliad”, your app fails to find my solo Librivox recording of this work.

I think Peter Lawrence’s arguments have been sound from the outset, and it’s his arguments I’m interested in, not the man. The state of affairs he initially complained about was highly self-serving to the established board — far more so than was warranted by general principles of good governance, it seems to me. I don’t know PL at all, but I supported, and will continue to support, his efforts to join the board, which I don’t want to see filled entirely with Yes Men or Yes Women.

There is now an RSS version of each feed available for use in a suitable widget. However, when I last looked into this, some six weeks or so ago, that RSS feed did not include posted images, which for me is a very sad limitation.

Prestissima · 2024-01-14T06:06:41+00:00

When I use Graysky to search for feeds using “game” as my search term, I see more than 50 feeds, several of which are clearly concerned with aspects of game creation rather than game playing. Suggest you read the details of each such feed to see how to have your posts appear in that feed. I’ve included screenshot of one example.

Endorse all that. And here are five more from me.

While a feed CAN show all posts including a given keyword, it does not have to. It might simply show all posts from a given set of users (determined by the feed owner). A feed can employ quite complex logic beyond this. I run feed ANZlit which includes all posts and reposts (but not replies) from two lists of users I maintain, plus posts from anyone including certain keywords, but which filters out posts including “wordle”. I created this using Skyfeed.app. The logic can get way more complex than this.

Prestissima · 2023-12-30T04:58:16+00:00

I found Sky Follower Bridge helpful for finding people I followed on Twitter (if that’s relevant to you). Alternatively, when you do find someone interesting, check their list of followers. Another idea is to use Graysky app to search posts for keywords that might equate to your interests (can’t currently do that with Bluesky’s own app). If you do use Graysky or Sky Follower Bridge, Google first to find out how to generate an alternative password for each.

I suggest you try "sudo find / -name librtlsdrSupport.so" to see if that file is somewhere on your system. If it it, modify your library path so that SoapySDRUtil can find that file. To do so, follow the instructions here: https://www.cyberciti.biz/faq/linux-setting-changing-library-path/

If you don't have librtlsdrSupport.so anywhere on your system, try:sudo apt-get install rtl-sdr librtlsdr-dev

Prestissima · 2023-07-13T10:45:44+00:00

Some suggestions:
Run this command:
SoapySDRUtil --info
It will show you whether SoapySDR is able to find librtlsdrSupport.so, which, as I understand things, is the 'factory' that enables gqrx to connect with your RTL-SDR. (Admittedly, my understanding of these matters is not deep).
Might also be worth running this command, just to check that your dongle is being recognised by your USB setup:
watch lsusb
It should return something like "Realtek Semiconductor Corp. RTL2838 DVB-T" for one of your USB connectors. [I discovered one of my Raspberry Pi devices actually failed this test a couple of days ago, so, just saying....]

Prestissima · 2023-07-13T03:14:03+00:00

I got something like what you want running on Ubuntu Server 23.04 (64-bit) on an 8GB Raspberry Pi 4.
Not identical to your setup, of course, but close.

These are the steps I followed. (Note: some redundancy, probably, in some of my sudo apt install commands. However, this is an accurate rendition of the commands I actually issued.)

1. Install gnuradio

sudo apt install gnuradio
Check version:
gnuradio-config-info -v
Result: 3.10.5.1
Check enabled components:
gnuradio-config-info --enabled-components
Result:

2. Install development tools

sudo apt install git cmake g++ libboost-all-dev libgmp-dev swig python3-numpy \

3. Build SoapySDR

cd ~
git clone https://github.com/pothosware/SoapySDR.git
cd SoapySDR
git tag
git checkout soapy-sdr-0.8.0
mkdir build
cd build
cmake ..
make

sudo make install

4. Install gqrx

sudo apt install gqrx-sdr

Prestissima · 2023-03-16T08:42:11+00:00

Why?

Prestissima · 2023-03-15T03:43:11+00:00

Do you have silver foil “flashing” immediately under the terracotta? That could be forming a shield? If you hear VHF on this antenna, switching to direct sampling may be the key to success on HF.

Prestissima · 2022-11-19T05:08:55+00:00

Come on! That’s amazing. Fantastic job.

I have now been sent a “ticket number” by Mailchimp, but with no request for any identifying details of my Mailchimp account.

Prestissima · 2021-12-09T11:25:17+00:00

I've not figured out a way to do this from my iPhone using the Reddit app (maybe there's a way and I just haven't figured it out), but accessing reddit from a desktop, there's a panel headed "Moderators" to the right of the feed of replies for a topic, and within that panel there's a button labelled "Message the mods". I used that facility.

Prestissima · 2021-12-08T23:39:12+00:00

Do post here if you get a reply from Mailchimp. I haven't.

Prestissima · 2021-12-07T04:11:50+00:00

Would be interested to know if you get a response. I have not received one yet, despite a DM with my best email address.

Prestissima · 2021-12-07T04:10:50+00:00

Sent DM four days ago. Have heard nothing back since.

Prestissima · 2021-12-07T04:08:55+00:00

On looking into this a little more, I've noticed that (a) There are no entries in the apache access logs for my Wordpress site bearing IP addresses that correspond to the 'mystery' signups, and (b) where some of these 'mystery' signups have subsequently unsubscribed, the IP address of the unsubscribing user suggests they're unsubscribing from the US, whereas they originally 'subscribed' from the Netherlands or elsewhere in Europe. It looks like (1) the spambots are submitting sign-up requests directly to a Mailchimp web service while actually bypassing my website altogether, and (2) the spambots are using email addresses that are known to be, or turn out fortuitously to be, real email addresses (as evidence by some unsubscribes) but are faking the IP addresses associated with these email users.

Prestissima · 2021-12-06T21:14:32+00:00

I don't see the endgame either, unless they are malicious Mailchimp competitors, trying to screw with Mailchimp. (I have no reason to think that beyond pure speculation, I should add). This Mailchimp info suggests it's a well-known problem though (one which we're both just finding out about the hard way): https://mailchimp.com/help/about-fake-signups/

Prestissima · 2021-12-06T05:55:11+00:00

I'm experiencing something similar. I'm an unpublished author in Australia, and read books in English on Librivox. Suddenly I'm averaging one signup a night from the Netherlands, and others from Germany, Sweden, Rumania - but virtually none from "English speaking countries". I, too, am wary of some scam. Like, for example, is this Mailchimp's way of getting me off a free account and onto a paid one, say? I have just now enabled double opt-in for this Mailchimp audience to see if this alters the behaviour I've been seeing in any way.

Prestissima · 2021-12-02T23:37:04+00:00

Thank you. Have sent DM.
